DIARY OF A STUDIO

1_FEBRUARY FIELDWORK

Last February 15-26, 20 KULeuven Mahs-Mausp international students and 4 KULeuven staff members went on a fieldtrip to Indonesia, South Kalimantan, Banjarbakula, Banjarmasin. The invitation was by UN-Habitat, implementing the initiative â&#x20AC;&#x153;Making Urban Investment Planning Workâ&#x20AC;? in partnership with the Directorate General of Human Settlements (DGHS) of the Ministry of Public Works. In Banjarmasin 17 Indonesian participants joined our students (City of Banjarmasin Government, South Kalimantan Province Government, University of Lambung Mangkurat, IAP South Kalimantan, University of Diponegoro, Ministry of Public Works and Housing, and Indonesian KUL Alumni). Partners for the event were UN-Habitat, YKKS/P5 UNDIP, Pemda Banjarmasin, Arcadis and KULeuven. The first results of this fieldwork-masterclass were presented during the CDS closing event in Java, Semarang 27-28 February. Allow us to once more sincerely thank everybody who made this fieldwork-masterclass possible, and also to apologize again for adjusting the carefully prepared fieldtrip schedule and agenda last minute, for the sake of building a more thorough understanding of the region. The warm welcome, sound support, inspiring enthusiasm, fruitful collaboration and wonderful company have been amazing. We would especially like to thank UN-Habitat Regional Office for Asia and the Pacific and Bappeda Banjarmasin. And underline the very essential full preparation work and guidance of Nini Purwajati, Cynthia Susilo and Stefanie Dens. Back in Leuven on Sunday 1st March sound and safe, no time to recuperate (except for unfortunate Tarek) from the hard labour. The day after, on Monday 2nd March, we summoned our students in the Water Urbanism Design Studio Banjarmasin, as we would do for the next consecutive 9 Mondays in a row (Easter holidays excluded). The Water Urbanism Design Studio would have the fieldwork as a start for Design Explorations by the 20 KULeuven Mahs-Mausp students. It is the summary of these Design Explorations we present in this booklet.

2_MARCH CONCEPTS

Fieldwork groups (tissue, water, production and infrastructure) were reshuffled in 5 design groups of 4 students each, at the very beginning of the design studio: an iterative process since we desired one member of every field group in the design groups, and mixing nationalities. The first weeks were to be divided in finalising the fieldwork in the booklet Explorations [1], and simultaneously setting up design issues derived from this fieldwork. Animated discussions started up as design group members brought along fieldwork issues they wanted to further investigate. And at the same time a large amount of more and less official plans and documents were analysed to build an understanding of all the challenges the Banjarmasin region would be facing in the near future. This information very often seemed uncertain, unclear or even conflictuous.

Therefore the studio would switch constantly between design group discussions and discussions with the full studio group, in an attempt to define specific design issues that are complementary to each other, and could support each other in a joint effort for envisioning a future for the region. At times the studio was thus considered as a semi-professional research group questioning the challenges for the region and how to deal with them. Trying to mitigate between the understanding of the territory from a meticulous fieldwork and the governments policies and projections. Trying to mitigate also between a genuine appreciation of local traditions and habits, and the projected pressure of a globalizing economy.

Soon it became obvious that it would be necessary to work not only in individual design groups, but also to work as one big group investigating a potential flexible spatial (landscape-) structure, derived from an understanding of the territory and preparing for a very uncertain future to come. From the very beginning of the design studio indeed, we received additional aspirations and expectations, and uncertain additional information, and this would go on during the full course of the studio. Some of the most upsetting information being a (serious) study for moving the Indonesian capital to Kalimantan (Palangkaraya or Pangkalan Bun) during the next 20 yrs, the announcement of Russian and Japanese studies for train infrastructures in Kalimantan, or upgraded national food efficiency programmes. Thanks Cynthia Susilo and Aryani Sari Rahmanti for keeping us updated and for your translations!

This booklet holds the studio topic, issues, and methodology, and the findings of the fielwork groups tissue, water, production and infrastructure. It holds the full list of participants and partners on the fieldwork-masterclass.

In a very short notice, 5 design concepts were tested in a mid review jury. Students prepared a design group analysis or statement, and formulated a draft design strategy. The statement maps are included in this booklet, while design strategies were further elaborated and refined during the second half of the design studio, and have replaced the first drafts.

We were very honoured with the interest of prof. Hari Wibisono who finally was not able to join the jury, and to receive prof. Sudaryono Sastrosasmito, Aryani Sari Rahmanti, Annelies Denijs, Yuri Gerrits, Matteo Motti, Julie Marin and of course prof. Bruno De Meulder as (guest) critics. The jury took note of the presented fieldwork and commented the first concepts. We remember prof. Sudaryonoâ&#x20AC;&#x2122;s involved comments on typologies (scales, history, community patterns) and the questioning of the uncontrolled development that comes along with the new infrastructure within the very sensitive settlement patterns. A vivid discussion took place related to the supposedly dramatically shifting conditions that would occur during the coming years. What is the time frame considered? If change must come, what kind of change, for whom? Same people in other spatial conditions or other people that may need other spaces and will do other activities? What kind of space or infrastructure will be needed? And what can this landscape bear? Isnâ&#x20AC;&#x2122;t the direct relation with the landscape alarmingly disappearing? This studio must take position!

Full group discussions multiplied, with or without the studio staff. A solid awareness of other design group’s aspirations grew, and design strategies started to leave room for each other and at the same time complement each other. The (attentive) reader will find elements of other design groups within the different projects. We consider this a true quality and an achievement of the studio as a whole.

3. Design

topography - the liquid territory of Banjarmasin

One vision explicitly triggered the interaction and reciprocity of design strategies: the ‘water’ design group came up with a very clear and sensitive strategy. It was as much innovative as it was pre-existing and thus conservative. A threefold strategy for runoff water (natural flow, activated drainage system, and enhanced storage capacity) combined with dealing with flood and saline intrusion pressures from SLR. It is based on a precision topography, and a solid understanding of existing water systems. At the time it felt like a breakthrough: a vision with excessive consequences! Therefore the water group did an extra effort to present this vision in an intermediate draft report, that we would try to double-check with water management experts. This did not really work out within the compelling time-schedule of the studio. The studio then decided to accept this vision as a structuring frame.

The occurance of floods and relation to ground water highlights an interesting situation around the site of explorations within the region. for instances of floding some of the internal areas suffer flooding during peak rainy season, scuh as areas between banjarbaru and martapura. Similarly regions near the mouth of the river face the worst underground water conditions.

2 RECEPTIVE LANDSCAPES successional transformation and recovery/open-ended absorption scenarios

Afforestation strategies (mangrove forests and foothill forests) strongly support this vision, while simultaneously inviting new economies (harbour related or manufacturing and food processing) as partners to help and apply these afforestation strategies. A Barito mangrove-harbour or harbour-mangrove? A foothill forest-city or city-forest? Time will tell. A thorough understanding of production processes and soil conditions supports these strategies. 3 ADJUSTING THE REGIONAL NETWORK IN BANJARBAKULA activating the latent urban system

The ‘infrastructure’ group exactly needed these clarifications to adjust the infrastructural network to the expected and projected change. A clear hierarchy of the mobility network is implemented, reusing as much as possible of the existing or planned infrastructure and restricting the necessary new investments. It distinguishes the need (and probability) of public transport on a Kalimantan, regional and local scale. It recognizes the need of a long-term vision that can be gradually implemented. It understands the important role of raised infrastructural lines within the very low lying territory, as a strong tool to implement the envisioned water strategy. But basically this vision tries to build resilience against the purely speculative habit of developing every new road along its borders. (Development thickens to the extent that the road gets saturated and must be replaced by the following, spreading sprawl all over the territory without a proper mobility flow.) The result is a clever positioning of infrastructural lines in line with the water vision and with the ‘receptive landscapes’. Finally, this consolidated territorial landscape- and network-frame initiated an explicit vision on the relation of Banjarmasin and Banjarbaru(/ Martapura). The development pressure along this 30 km strip can be considered as the catalyst for the sprawl condition. Banjarmasin and Banjarbaru together tend to form a linear city. But this is happening in a flood prone territory with bad soil conditions: Gambut low lying area, swamp, space for water storage! The thickening of this development along

5_JUNE FINAL REVIEW

Jeneral Ahmed Yani (Transkalimantan road?) is furthermore congesting the major infrastructural spine, whereas extra room should be made for intercity (public) transport passing the Syamsudin Noor Airport. Banjarmasin and Banjarbaru must be understood as clearly separate cities, with very different characteristics and very different future potential. At the same time they are closely related and dependant one another, in a delicate balance. They share the airport and drink water facilities, as they may share the future train station, water park, natural water purification systems and power supplies? Twin cities?

This studio was a fine journey! Thank you students for your enthusiasm and pro-activity! The combined plans and captions seem to make a coherent story! Overall gevernment policies are confronted with territorial realities. It would be great if some of the proposed strategies - either based on incomplete (traffic) counts during fieldwork, or developed more intuitively due to lack of correct numbers (waterflows) - could be evaluated with more precision? We are pleased to present this work to policymakers and stakeholders, hoping it helps to envision a possibly sustainable future for a region we have come to appreciate in very many ways!

4 BANJARMASIN_COLOURING THE POLARIZED CITY Banjarmasin - traditional river city - located at Barito River is the harbour city as ‘gateway to Kalimantan’. It sits delicately on the slightly raised riverbanks, surrounded by floodable (swamp) territory. It urgently needs to clarify protective strategies against flood risk and saline intrusion. But some of the expected new development may be crucial to the region’s economy and should probably be absorbed here? The harbour is shifting towards the Java Sea, whereas universities and public amenities shift towards the Transkalimantan road and Barito Bridge in the north. The traditional city quarters and Kampongs experience pressure from infrastructure and development. The typical harbour city at one side of the mighty river is everything but radio concentric, so it should not need a ring road. But the main city road is blocked by through-going traffic. And how can Banjarmasin cherish its water-based origin? The Banjarmasin group investigates potential new identities for the polarized city that are in line with its landscape (and waterscape) and with its territory. 5 BANJARBARU_FRAMING THE ADHESIVE GREEN ARMATURE Banjarbaru on the other hand sits (with Martapura) safely on the dry edge of the swamp at the foothills of the mountain range, as a slope city, and has good soil conditions. It has a history of distinct natural settlements and consecutive planned urbanism. Lately the provincial headquarters were founded here. But (the periphery of) Banjarbaru is sprawl-like and still holds a lot of potential for densification. Banjarbaru holds many identities. Today it lacks cohesion and consistency and a clear urban structure. Water run-offs from the higher grounds pierce through the tissue. The Banjarbaru group investigates the characteristic open (green) spaces around these water bodies as a potential adhesive structure, and as a necessary complement of the road network. A potential for Banjarbaru to receive new programmes and more housing, and to simultaneously gain urban qualities?

STRATEGY - The idea is to manage water and landscape in such a way that it allows to provide space to extend for the city but also for the economic activities and most certainly for water itself. To reach those goals, the strategy is to connect people, green and water to form one common language. The idea is to boost a compact development north-south of the cities in order to reinforce their own and distinct identities and to preserve a natural protected area between the two urbanized zones. This way we can direct water through this corridor instead of to the cities and re-organise productive landscape and waterscape. Taking time into account, the strategy is to reinforce drainage and storage of excessive water during the wet season while increasing flows and irrigations during the dry season to ensure production, life and security.

Strategic project for Banjarbakulas water management

The approach is to create a blue corridor between the cities to give a path to the excessive water from the foothills down to the sea and to reduce pressure on Martapura river and Banjarmasin. The city becomes an island using infrastructure like dikes and doors letting the water cross or blocking it following the needs. Coming from the foothills water has different itineraries to join the sea without flooding Banjarmasin: an almost completely man-made and controlled system in the north with the polders and canals network, a mostly controlled system through Martapura river and Banjarmasin city, an almost not controlled and natural system in the south through the creek landscape. 20

Taking time into account, the strategy is to reinforce drainage and storage of excessive water during the wet season while increasing flows and irrigations during the dry season to ensure production, life and security. Looking at the territory, its landscape and its landuse, we can develop alternative ways of interpreting it. It is crucial to consider the existing situations and recognise its potentials. Water is more than streams. It becomes a resource, part of the public realm, supporting activities according to each landscape types and to seasonal landscapes. But the quantity and quality of water can easily become a massive issue if not handled properly. Looking

at the landscape with the intermediate scale allows to answer both large issues and specifi c needs and conditions. This way the landscape is shaped based on a multiscale approach both from a stakeholderâ&#x20AC;&#x2122;s point of view and from a landscape and development one.

PHASE 1

PHASE 2

The development plan of Banjarbakula is mainly in line with the presented strategies. Whereas industries and unified urbanized area are not part of the strategies, several actions are similar (forest, peat, mangroves, fisheries, ...)

The crucial points are developed in order to manage the main water issues while protecting the cities and redirecting the flows.

PHASE 3

PHASE 4

Lines are reinforced while offering more specified opportunities to middle scale stakeholders in order to intensify the potential of the region.

Small scale appropriations of the new landscape and waterscape are implemented, collecting the benefits and multiplying stakeholders in a more individual scale.

WATER RESERVOIR

The wetland is associated with cleansing systems, storage areas and intensive productive landscapes that defines the transition between the city and the wetland. The waters of Banjarbaru are collected to be cleaned in a park mixed with orchards before joining the wetland.

After the wetland, the water passes through a cleansing waterpark forest before joining a storage area. Forest and storage are located in productive peat forest in order to take advantage of the high retention capacity of peat soil while protecting the region of ground fires in dry season.

mid review map: a reading of threatened landscapes

READING - The map diagnoses the conflicts in the landscapes under threat especially if the current trend of land use was to continue. Troubled landscapes are an expression of the evolution of time in ever increasing development and the search for better livelihoods. The threat increases with the passage of time spent in the same trends. Excavations and mines will expand, ecosystems will continue to shrink 26

and plantations will fight forests for space. The contradiction is landscapes that have been heavily invested in but have not met their full potential. The level of irreversible damage is fast approaching requiring a strategic that takes into account the communities living in the region, the resources and the time factor.

STRATEGY - Diverse landscapes are under threat by the current use of land and the demand for absorbing the new. The level of irreversible damage is fast approaching; requiring a strategy that frames a balanced, systematic transformation and recovery. By

taking advantage of the existing conditions of each landscape a feasible groundwork for the future is shaped. This project focuses on the mangrove and mining landscapes because of their strategic location within diverse conflicting edges in the area and their capacity to receive

the new along with enhancing the ecology. We consider three scales of transformation within a timeframe of fifteen years that shows a scenario, an open ended story for an uncertain future.

Two territories; mangroves and mines, in transformation are holding the capacity to absorb and receive the new. A strategic plan gives way to different possible scenarioâ&#x20AC;&#x2122;s: Ecologically driven, development driven and a balanced scenario of the two previous. The strategies for transformation are to rebuild mangroves on the river edge and to do reforestation in the foot hills. These strategies are projected in different phases with small steps of interventions. The mines are exceptional landscapes that gives space for production, flood protection, facilities and services for future growth, ... while the mangroves provide room for new economies and reestablished ecologies.

ADJUSTING THE REGIONAL NETWORK Activating the latent Urban System Baidya Emerald Upoma, Bosmans Claire, Matton Isabelle, Tran Trung Vinh

The ‘infrastructure’ group exactly needed these clarifications to adjust the infrastructural network to the expected and projected change. A clear hierarchy of the mobility network is implemented, reusing as much as possible of the existing or planned infrastructure and restricting the necessary new investments. It distinguishes the need (and probability) of public transport on a Kalimantan, regional and local scale. It recognizes the need of a long-term vision that can be gradually implemented. It understands the important role of raised infrastructural lines within the very low lying territory, as a strong tool to implement the envisioned water strategy. But basically this vision tries to build resilience against the purely speculative habit of developing every new road along its borders. (Development thickens to the extent that the road gets saturated and must be replaced by the following, spreading sprawl all over the territory without a proper mobility flow.) The result is a clever positioning of infrastructural lines in line with the water vision and with the ‘receptive landscapes’. Banjarmasin and Banjarbaru must be understood as clearly separate cities, with very different characteristics and very different future potential. At the same time they are closely related and dependant one another, in a delicate balance. They share the airport and drink water facilities, as they may share the future train station, water park, natural water purification systems and power supplies? Twin cities?

ONGOING - The way infrastructure is currently produced in the Banjar Bakula region and in Kalimantan has oversimplified the role of ecology and underplays the social aspect of urban infrastructure by an extreme reliance on efficiency. Being at a turning point in the region development, it is the occasion and the necessity to think about territories in another way, more in terms of quality and character.

COLORING THE POLARIZED CITY Kathleen De Beukelaer, Saima Musharrat, Hanne Van Gils, Amaranta Vargas Mendoza

Banjarmasin - traditional river city - located at Barito River is the harbour city as ‘gateway to Kalimantan’. It sits delicately on the slightly raised riverbanks, surrounded by floodable (swamp) territory. It urgently needs to clarify protective strategies against flood risk and saline intrusion. But some of the expected new development may be crucial to the region’s economy and should probably be absorbed here? The harbour is shifting towards the Java Sea, whereas universities and public amenities shift towards the Transkalimantan road and Barito Bridge in the north. The traditional city quarters and Kampongs experience pressure from infrastructure and development. The typical harbour city at one side of the mighty river is everything but radio concentric, so it should not need a ring road. But the main city road is blocked by through-going traffic. And how can Banjarmasin cherish its water-based origin? The Banjarmasin group investigates potential new identities for the polarized city that are in line with its landscape (and waterscape) and with its territory.

Reading of Banjarmasin

Banjarmasin is a key city that will grow rapidly. In order for the predicted doubling of population to take place, the growth model of the city needs to be closer looked at. Following the current trend, the edge of the city forms the first layer of possible urbanisation. As this 46

already causes some difficulties for the waterbased landscape, the question arised how this growth can take place differently. On top, it can be even stated how the new development can improve the old. Shifting from a concentric model towards a polycentric constellation, the

city will regain present identities including both present conditions as well as additional inputs. By shaping a clear urban figure and proffer a toolbox of actions, a transformation of the city will occur.

NEW DEVELOPMENT

FROM CONCENTRIC TO POLYCENTRIC GROWTH Banjarmasin is a key city in the Banjarbakula region, framed all around by water. It is founded on the highest spot in which multiple rivers collide, resulting in a traditionally highly-water based growth. Nowadays, the city expanded between the rivers and is moving more and more within its edge. De-attached new developments and generic implementations as ring roads, reinforce this landscape-ignoring evolution. At first glance, the edge of the city forms an important area of tension as it will be the first new layer to be urbanised

REINFORCING THE INTERMEDIATE SCALE Each district will base itself on its specificity in order to induce change, created by a strong urban figure that symbolises the system of transformation. On the highest scale, it starts to question the collaboration of city, the 48

developers and the (future) inhabitants. In order to invest in the poly centre, all of them will have to place themselves in a set of rules. Zooming in, the specificity of each district, will come into place. Today, various spatial conditions are present and have the possibility

to recalibrate the new urban system resulting in a new spatial figure with more pronounced hierarchy of these conditions. All together, this results in various spatial scenarioâ&#x20AC;&#x2122;s on site, which also include the social dimension of each poly centre.

As the waterbody in between Banjarmasin and Banjarbaru will clearly divide the two cities, Banjarmasin will have to opportunity to be more explicit framed. The multiple centres allow to pursue the lingering identities present in the current condition. By directing the growth of the city towards these nodes, it allows the city to preserve its productive and water-regulating landscape in between or even be strenghtened waterscapes as wetlands. The specificity of each polycentre will be brought to the surface, resulting in various strategies. Covering the different designs, each searches for connections within the spatial as well as the programatic and social relations. A new urban system colours this transformation towards a polorized city.

The Trans-Kalimantan road forms the catalyst for the Northern part of the city. It holds the potential for having new typologies and being charged with urban elements. Bordered by an orchard system, the starting point is the green. The design strategy is to bring balance between the upcoming settlements and existing green. Taking the design toolbox as checkbox, the new developments are to add the improved living qualities that the city is missing. By connecting the voids with a green corridor and transforming them into platforms for large-scale functions, i.e research centre, university, commerce, park etc; the strategy tries to break the current mono-functionality of the area and giving it an identity which is more than only living.

Being the oldest road since the birth of Banjarmasin, the Martapura Lama holds great historical significance, including the commercial character. The challenge is thus to create conditions that would strengthen the traditional attributes of river settlements as well as creating new points of opportunities. In regional scale, this area lies in an important crossroad that can purify and retain the upstream water in a natural way before entering the city. Specific design strategies like connecting the water lines, upscaling small-scale industries and creating eco-tourism and recreational facilities provide for the future. All these, naturally, can be connected by introducing public water transport and reprofiling the existing road. By sharing common platforms of facilities, the new can meet the old while building an image of traditional, cultural and artisanal identity.

As one of the main links between Banjarmasin and Banjarbaru, A.Yani road has gone through great transformation in recent years, which is mostly turning the buildingsâ&#x20AC;&#x2122; front facade towards the road into linear and dense commercial corridor. This has often been done by razing the first layers of dwelling and blocking the water. As a challenge, this road asks for creating beneficial choices for living and working by taking advantage of the existing landfill and references from landscape. Our design strategy gives orientation to the spaces by equipping the road with public transport, generating secondary connections by strategically replacing bridges and making space for public facilities. Using the existing cross roads and water lines, micro worlds are created, while the landscape keeps flowing through. Layers of zoning redefine the spatial hierarchy providing options for a healthy urban mix.

Banjarbaru on the other hand sits (with Martapura) safely on the dry edge of the swamp at the foothills of the mountain range, as a slope city, and has good soil conditions. It has a history of distinct natural settlements and consecutive planned urbanism. Lately the provincial headquarters were founded here. But (the periphery of) Banjarbaru is sprawl-like and still holds a lot of potential for densification. Banjarbaru holds many identities. Today it lacks cohesion and consistency and a clear urban structure. Water run-offs from the higher grounds pierce through the tissue. The Banjarbaru group investigates the characteristic open (green) spaces around these water bodies as a potential adhesive structure, and as a necessary complement of the road network. A potential for Banjarbaru to receive new programmes and more housing, and to simultaneously gain urban qualities?

The existing green flows inside the city of Banjarbaru are currently part of a fragmented and dispersed urbanity, or being suppressed from the expanding urban tissue. The hidden potential of these flows is crucial for the new city, as they can constitute the new public spaces for the dense structure. Reversing polarity from negative to positive, they create ecological corridors that work together with the drainage system, while at the same time, connecting to the waterscape. In the framework of a compact but porous city, the green flows have a crucial role.

1_INTRODUCTION Historical evolution Banjarmasin is typical example of development of Asian cities, growing out of an initial traditional nucleus and expanding due to impact of colonial and contemporary events. The city grew as a strong maritime trading settlement, trading mostly in pepper along with fruits, forest products and precious gemstones with China, India and Europe3. The earlier production fields were present along the slanted dry landscapes as most of the marsh and swamps were unexploited and uninhabitable. Martapura river became the safe,efficient and the only connection between the port of Banjarmasin and the hinterland. This led to the early settlements and agriculture along the Martapura river. The end of 18th Century saw the decline of the pepper trade due to exploitation and the trading importance of Banjarmasin was lost. The 19th century discovery of Coal and trading of natural resources has once again revived and established Banjarmasinâ&#x20AC;&#x2122;s economical role within Kalimantan.

1927 - River and Road as complimentary system. Rice feilds only present in upstream communities.

Multifunction role of water Banjarmasin is the largest, significantly water oriented city in Kalimantan Island. The regions economical position has further strengthened its multi-functional role as space for settlements, daily use by inhabitants, sustaining agriculture and aquaculture, production of hydroelectric power. It also supports numerous small and large scale industries, mining and coal extraction, used for discharging of waste water and as a mode of transportation for finished and unfinished materials and imported goods the port. Production, Processing and trading diagram4 shows a complex relationship between production, processing & trading activities in relation with water & road network in the region. New conflicts are emerging due to increasing shifts towards road based infrastructure, which is considered 3 SAIDY, A., R.; AZIS, Y.,

a faster compared to waterways. Large scale activities such as coal manning and palm oil plantation are considered to be the new threats, though very small areas are within Banjarbakula, but large scale mining and palm oil estates are threatening the rivers upstream, bringing pollution, increase downstream sedimentation, increase flood risk and have reduced productivity by increasing pH value5 in water.

Current Situation - Abundance or Scarcity? The series of images represent a dichotomy of water and its impact on the growth of the city and region. The increase in seasonal variation is altering the landscape, settlements and might also play a negetive role in the economic aspiration set out by the regonal authorities.

Regional growth â&#x20AC;&#x2DC;Banjarmasin and Banjarbakula, South Kalimantan, feature prominently in the medium-term plan Indonesia 2014-2019 of the Indonesian government: Simultaneously Banjarmasin is undergoing a dramatic transformation, shifting its waterbased origins towards road-based transportâ&#x20AC;&#x2122; â&#x20AC;&#x201C; Context for Urban planning and design studio 2015. The feildtrip revealed that the increased purchasing capacity of the inhabitants has allowed them to invest in private automobiles and also better quality housing outside the city. The peripheries of both Banjarmasin and Banjarbakula are dotted with private housing development due to more value in real estate. The road infratructre is being given priority and has led to similar fate of strip urbanization along the major urban coridors such as Ahmed Yani and the upcoming port road. The future metropolitan area without the lack of a visionary policy might lead to Banjarmasin and Banjarbaru become a continous urbanized strip, lacking identity, and less connected to its landscape.

Overlapping Regional Conditions with flow networks

Economic Role of water in Production Water plays a significant role in the economy of Banjarmasin, with provision of water supply to the trading ports, hydroelectric production, and water for irrigating and water transportation routes for transporting coal, timber and other forest products. Water also supports the two important household industry of food production for local markets and Sasirangan cloth. The port, regional markets, transportation and warehousing, services and finance supported by water related activities constitute 50% of economic activity in Banjarmasin6. The Comparison of the of decadal reduction in rainfall, reduction in agriculture production and increase in estate plantations and construction activities reflect change of economic priorities are changing due to un predictable water availability7. The economic profiling during the fieldwork period revealed that water plays a crucial role in the large scale (Port, Processing, inter-island transportation) and small scale (Household agriculture, orchards, fishing, shrimp farming) economic activities of the region. The medium scale activities compose primarily of the trading and transaction and mid scale processing activates giving rise to increased dependency on road infrastructure leading to speculative warehousing corridors along the two key roads in the region. Many small and medium scale activities show a co-productive relation due to use and reuse of water creating a complex network of economic flows8 spread along the Banjarbakula region, yet tied to the framework established by the water landscape

Role of large scale projects in transforming the landscape? The process of initial occupation of the swamplands began with the 19C Dutch canals connecting the Kapuas and Barito River and opening up swamps for occupation and polderization9. The post-independence period saw a number of development projects, aimed at increasing food production. Tidal swampland development 1960, Transmigration 1960 to 1980, and Mega Rice projects 1996 having immense impact on the wetlands of South Kalimantan. These projects aimed at reducing poverty by rural development, promoting agricultural production to boost economy and natural resource conser-vation by intensive and diversified agricultural practices10 . The migrating population due to different agricultural practices significantly altered the landscape replacing traditional agricultural practices. The peat swamp acted as water holding reservoir during floods were affected by reclamation projects. Peat swamps become dry leading led to frequent fires, acidic pollution of water.

Land conversion to Oil Palm plantation - The mediocre yeilds and increased acidity of the soil led to failure in rice production. many such territories around banjarmasin are being converted to Oil Palm Plantaions. 11 Palm plantation require forest clearing, leading to removal of essential biodiversity and old vegetation leading to washing of nutrient rich top soil. Palm oil has provided much needed financial gains to land holders, yet in longer run they led to total degradation of land, water resources and have drop in productivity.

3_A WORKING LANDSCAPE Watershed Impact over Banjarbakula region Watershed study at the scale of Kalimantan is very crucial as Banjarmasin itself is located at the southernmost point of the basin. Banjarbakula region is part of the landscape shaped largely by the Barito River watershed,. It also includes the watershed regions of Martapura, Alalak, Riam Kanan and Riam Kiwa Rivers. Riam kanan watershed covers an area of 1000 SqKm It is more important for the banjarbakul region as it provides water for the Dam (power, flood control and irrigation). It is identified as one of the critical watershed within Indonesia 14. Significant part of the Barito watershed and Martapura sub watershed has been affected by the agriculture, grazing, gem stone mining, leading to heavy silting of the rivers. Further reclamation of swamps for housing and warehousing projects further reduces the water holding capacity and increase risk of flooding in future. The increase in mining, crop estates upstream amplifies the downstream impacts such as reduced productivity, flooding etc15 . A major part of the lower watershed lies within the Banjarbakula masterplan region,. Due to the low lying marsh/ swampy character and location it is continuously affected by the tidal and fresh water fluctuations. Further urbanization, increase of industrial activities, expansion of port and development of regional infrastructure, (roads and railways) need to be carefully planned for both use and risk prevention in relation to water.

Revealing the landscape qualities. The Banjarbakula region require a deep analysis of its topography and geology, to reveal the hidden landscape potentials and also presenting distinguishing characteristics enabling us to divide the landscape into distinct parts. The Foothills - Are the primary forests for the water catchment. They received the early migration settlers primarily cattle herders from from Madura islands, who initiated the conversion of primary forests into productive forests and grasslands. Today the landscape includes production of rattan, minor forest products, gemstones and mining, house hold scale rubber due to its nutrient rich soil.The hills also have soil which allow water penetration.

Foothills - Potential for developing forests. Source: Studio Group work.

Riverbed Peat Swamps - the low lands present a different hydro-geological composition with seasonal or permanent water logged conditions. A significant (129.3 SqKm) area of the marsh is also occupied by peat swamp. Peat swamp has various benefits such as capacity to absorb water up to 850% of its volume. Acting as a huge water reservoir it provides resilience to saline intrusion, seasonal floods provide downstream water for irrigation during dry season and act as an ecological carbon sink. Peat swamp in itself required huge amounts of water above it surface, during dry season many fires are reported in the peat swamps in Banjarmasin.The existing peat swamp along Ahmed Yani Road area is reclaimed for development, which poses a threat in future. Riverbed Marshes - The wetlands are an important source of freshwater fishes, duck farming to supplement rice production in rural areas.The traditional practices of burning the water hyacinth allowed the nutrients to return to the ecosystem, benefitting the aquaculture and produce paddy, galam wood, fishing, water chestnut cultivation and house hold water.

Lowlands swamps and Marshes dominate the landscape of Banjarbakula regiona. Source: Studio Group work.

Climate change challenges and impact Banjarmasin and its surrounding areas are below or equal to sea level. This condition leaves the region vulnerable to climate change such as Sea level rise (SLR), increase in upstream floods and saline intrusion of agricultural land. Reclaimed tidal swamplands which are crucial to the economy of the region will be significantly impacted by the sea level rise, risking the livelihoods of farming and agricultural communities. Provinces of Banjarmasin, Banjar and Barito Kuala are already impacted by the SLR. SLR of 0.45 M can lead to 50% loss in 40 years and 100% loss of production in 66 years production of rice fields, fruits and fish/shrimp farming.16 Saline Intrusion Level - The zone around Banjarmasin is already effected by saline instruction. The tidal rise, dry irrigation channels during summers has aggravated the intrusion further. The peat along the eastern periphery of the intrusion shows resistance due to its freshwater holding capacity. Source: Author

The design approach was to create three distinct zones i.e. absorption zone in foot hills, retention zone as the transition between dry to marsh and finally the discharge zone being the City and the agricultural areas south of the city. This approach helps on creating improved utilization of water resources in conjunction with supporting landscape. Water management based upon the existing and future possibilities helped to draw a water frame, capable of promoting upscaling, co-production amongst the stake holders and absorbing future economic activities.

The following text looks at how these three zones benefit water management and presents cases of traditional, hybrid and future land management techniques based on water first approach. The case studies are real examples based on upscaling and co-productive strategies which are dynamic, accommodate changes and benefit the population supporting both the Economic and Ecosystem relationships. The UNEP Millennium Ecosystem Assessment (2009) states that water management based planning provides direct benefits such as natural resource preservation and production enhancements with improved water quality, flood regulations, habitat conservation.

The retention zone consists of the vast foothill swamps and low land marshes wetlands. These wetlands have immense potential for holding water and impove the regional landscape quality. These wetlands along with the occurance of peat can become the regional water reservoirs, provide an expanding landscape for water during rainy reason. They also trap sediments, promote flora and fauna and can support public programs, ecological parks and support medium to large scale production/Processing zones for fisheries. or orchards.

Zone 3 - Discharge Zone The third and the most urbanized zone is the discharge zone. It proximity to river and to the river/sea estuary creates two different conditions and requires different strategies for development. The city-river sections should be removed of encroachments and develop flood proof infrastructure and urban floodable terraces within the city. Our project foccused more on the River/sea estaury zone as its the part which will accomodate the future urban expansion. Looking back at the qualities of landscape the most appropriate strategies would be integrate develop a sequence of water pools supporting village development, agriculture and aquaculture to counter the salinty risk. Many farmers are shifting from paddy to shrimp farming, whihc over a period of time will gradually increase salinty in soil. The strategy is use land profiling and multiple use for growing fish/shrimp and ricea and water vegetables.

Case Study - G2 Productive, profitable, resilient agriculture & aquaculture systems project India and Bangladesh is aimed at Improving year-round aquaculture & rice-aquaculture productivity in salinity and water logged conditions. This practice can withstand the increase of 30 to 50 cm of water rise, and support more than two rice crops along with growing fish and vegetables. These practices have promoted cost and labour effective co-productive water management by involving indvidual farmers.

5_CONCLUSION Water is essential for all human settlements, and more so for Banjarmasin. The studio studies shows that current urban expansion will continuously reduce the space for water and also impact production. The challenges for such an expanding region can be summarized primarily as flood risk, space for urbanization, ample economic opportunities, food and water security and identity. The watershed/water management based approach requires attention and planning right from its source to the confluence. Carefull assement of landscape and land use practices and thier relationship to water. In our case the Riam Kanan basin should be considered a priority zone and included as part of the Banjarbakulaâ&#x20AC;&#x2122;s Vision plan. A successful vision can be become the success story for adaptation along the Barito basin. The project conceived for Banjarmasin is result of overlapping natural systems, landscape qualities, existing production practices and spatial possibilities for future, which are based on the existing conditions of Banjarmasin. A strong water management approach will create multiple use of the existing space, creating new productive opportunities and providing natural ecosystem services. The shift from the generic land use to a more sensitive location specific water centric approach has to be thought as a long term process which requires a long-term planning process. It will require detailed data collection and mapping of the region. Finding the right stakeholders and educating them for developing partnerships, appropriating clever investment from both public and private sectors and the combination of environmental and technological advancements. The approach, process and implementation of a water vision itself will create a nature like evolving network, generating small, medium and even large scale activities providing immense economic opportunities and support the expanding population in a holistic way. 41

Hidden story of wetlands’ synergy Potentials and threats of wetlands to Banjarmasin ‘desa’ and ‘kota’

WATER SHIFT, the manmade system destroyed the wetlands’ ecology and caused serious flooding

THE SHIFT The dramatical shift in plantation causes the loss of wetlands area. In the past Banjar districts were developing along the linear structure of water bodies. New canals and Irrigation were set up in 1919 during the Dutch came but not yet destroyed the patch work of existing water patterns. When the new Dam was constructed in the late 1930s and A. Yani road came in 1942, these provides system for water and transport serving for intensive farming and paddy cultivation. The shift from natural swamps to tidal rice swamps, more or less still enhancing the wetlands ecology. However, we all know, agriculture industry may cause pollution water resources, Also the shift from waterbased urbanism to road-based urbanism turned wetlands and rivers into backyard for gabbage dumping. Now the problems started seriously. One of the threats nowadays causes disappearing of Banjar wetlands is Plam plantation, This is a cash crop but consequencely a disaster if not being wellmanaged by the government. Intensive plam puts wetland in danger because they dried out the land by dense irrigation system, and damage the soil, especially on peat soil. However, there are many sustainable adaptation for plam oil plantation if they were planted in mix crops or multi crops together with forest ecogoly.

PLANTATION SHIFT, the dramatically changes from swamps to dried palm plantation within recent years 6

DESA: In Banjar districts’ “desa” environment, the counties Martapura has an extensive freshwater wetlands becoming suitable for raising fish. Vegetable production is also a household activities for income. Variety species can be found here as: water spinach, nut, paddy, Rambai trees, lotus, reeds, etc. Apart from those who raising fish and growing vegetables. Matapura kampungs are very lively with traders, retailers, porters, auctioneers, people making nets, handicrafts, etc. A great many people... and poor people depending on the Wetlands for thei livelihoods.Wetlands often refer to economic value because they help inhabitants in this rural area. Wetlands themselves provide commodities, but they are also a processing place for those goods. For environmental benefits, wetlands play variety of roles as water infiltration, flooding management and natural proccess maintenance. However, the government is less monitor these areas. As we know, the less control will lead to more spontaneous private development covering up the swamps. Acknowledging about wetlands can teach farmers to be self-improved in skills and technic. For example, developed wetlands towards the biological resources (fish agriculture - forest) and energy (biomass, hydropower, solar energy). In coastal swamp community, they can learn the mix agroculture (fish-shrimp, paddy, mangrove) natural disaster prevention (extreme floods, winds, storms), and maintaining water quality for further crops. Farmers can be teached to be protector.

KOTA: In the urban conditions, besides of constributing to bio-diversity, wetlands can play a role as parklands which contributes to a very important aspect of visual quality. This usually reflects the real estate increase. The relation between economic value of real estate and parkland is the distance between home and park, the nearer, the higher. Moreover, â&#x20AC;&#x153;the natural sustainable features of neighborhoods are always evaluated by residents as a desirable places for social interactionâ&#x20AC;? (Noiseux and Hostetler, 2010). Therefore the value of real estate increase due to proximity to the park. For Banjarmasin context, instead of being a backyard, gabbage collector, and sewage ponds, wetlands can be transformed into a new public park, which is just only 10km away from the city center. The desire of wetland park not only serves for Banjarmasin citizens but also for next coming of Banjarbaru citizens due to its inbetween location.

WETLANDS ECOLOGY in South Kalimantan

According to this new program, wetlands have additional culture benefits for children, where designer can provide enough open space with vaious out-door activities to encourage active play (Ozdemir, Yilmaz, 2008) and opportunities for children to learn about ecological functions and food production (McAleese and Rankin, 2007). In summary, there are growing evidences which showed that human contact with natural features in the urban environment can help to reduce stress and promote well-being, leading to greater community pride, and increased social interaction and ties (Alberti, 1999 and Chiesura, 2004).

Science of Tropical wetlands Wetlandsâ&#x20AC;&#x2122; definition in tropics â&#x20AC;&#x153;Wetlands are areas where water covers the soil, or is present either at or near the surface of the soil all year or for varying periods of time during the year, including during the growing season. Water saturation largely determines how the soil develops and the types of plant and animal communities living in and on the soil. Wetlands may support both aquatic and terrestrial species. The prolonged presence of water creates conditions that favor the growth of specially adapted plants and promote the development of characteristic wetlands soils.â&#x20AC;? (USA, EPA, 2012). Wetlands vary widely due to both local and regional differences in topography, soils, climate, water condition, vegetation, and also human factors. There are different needs for distinguishing among hundreds types of wetlands, so far, no single wetlands classification system is being used. Indeed, in tropics, particularly in Banjarmasin case study, two general types of wetlands are recognized: tidal wetlands (as coastal area) and non-tidal wetlands (as inland area). Defining by vegetation typologies, Banjarmasin periphery has three types of wetlands. The first one is Marshlands, which have soft-stemmed vegetation and plentiful nutrient soil conditions. According to the studio site visit, there two sub types of marshes: tidal marhses (i.e, riparian marshes) and non-tidal marshes (i.e, wet meadows, productive fields, sinkholes...). Secondly, Swamps where wetland is dominated by wood plants have two sub types as forested swamps (with hardwoods) and mangrove swamps living in fresh, brackish and saline tidal water. The last one is Peatlands characterized by spongy peat deposits. Surrounding Banjarmasin, we also found a complex peatland condition where the forested bogs live side by side with the shrub fens.

Multi use of wetlands in tropics • Filter: They filter pollutants and excess nutrients out of water, as it soaks into the ground. Sponge: They absorb stormwater, reducing the risk of • flood. This slow absorbtion also allows for much of the water to soak through the soil, recharging our ground water supply. • Nursery: Many species of amphibians, mammals, reptiles and birds rely on the safe wetland environment to raise their young. Wetlands often lack the large fish species and other predators that may feed on their young. • Hotel: Many migrating waterfowl, shorebirds, and songbirds rely on stopping at wetlands during their migrations in the spring and fall. Wetlands offer a wide variety of high protein organisms for them to feed on, allowing them to refuel.

SEWAGE SYSTEM, comparison between hard engineering and natural system. Another benifit is open system saves much money than the underground one.

• Home: In addition to the other wildlife mentioned, countless small organisms (insects, worms, snails, leeches, crustaceans) and plants make wetlands their home. Wetlands offer a very unique habitat. Recreation destination: They provide beautiful views and • plenty of opportunities for recreation (birdwatching, canoeing, hunting, exploring). Different from the hard engineering system, which just only transfers the pollutant from one place to another place, wetlands can be considered as a soft engineering to purify and manage both surface and underground water. Moreover, “not just only use for pollutant treatment, wetlands is also recognized as an riparian buffers functioned in many different ways depending on the size itself” (Hellmund and Smith, 2006). Managing urban wetlands can be challenging due to the competition between demands of wetland habitat conservation and the need for recreational, educational and scientific opportunities for people. Nevertheless, multiple uses must coexist in an urban environment (Zedler and Leach 1998). So that the only thing left is deciding how best to coexist with increasing interesting of people. Designers should make decision of which area is limited to the public and which is allowed low-impact recreation as well as the place for intensive public activities.

Recovering device The mechanism and cycles of exchange to recover the urban - nature ecology 10

EXCHANGE DEVICE Basing on the character of tropic condition: high temperature, a year round strong sun light, extrem rainfall in one season and dry in the other period... Banjar districtsâ&#x20AC;&#x2122; area can be divided into three possible major practices of water purification: Lagoons occupied on the low-lying downhill of Banjarbaru city are collecting wastewater from the city and serving for the new coming population. Gambut forest working as a natural proccess which can absorb and recycle wastewater from productive activities. With the abundant peatsoil, preserved peat forest can serve as a multi defense of saline instrusion. Wastewater treatment can also used in Productive wetlands as the indigenuos way farmers using in rural area by fisheries and growing paddy together with vegetables on gabbage or sewage compost.

This kind of system can give more opportunities to Banjarbaru city where the lagoons is situated on downhill side with advantages of micro-topography slope and in between many flows of blue and green system. This gives possiblity for lagoons to be catchment area and revives the ancient water flows to be once again an important part of the city 11

Intermediating scale Water management in time - space (scale) framing productivity and public domain GAMBUT: In South Kalimantan, peat subdistrict can be found 17 kilometer away from Banjarmasin city with 12 930 hectares which is 2.77% of Banjar district. Peatlands have high porosity as waterlogged areas, which can absorb water up to 85% of its weight. Therefore it has ability to prevent flooding during rainy season; moreover, it reserves water in peak event and can release water during dry season, in which case it has much potentials in prevention of saline instrusion. At the coastal area of South Kalimantan, there are multi layers of peatlands which give great potentials as a multi defense of saline instrusion together with the mangrove ecobelt. The peat itself as a back-up resources not only stores water but also provides vegetables and food resources, wildlife, and energy sources. However, intensive plantation is rapidly expanded reclaming peatlands for agriculture. This would damage the ecosystems, and in the end, the shift of peatlands’ function leads to serious flooding. Actually, the peat bogs in South Kalimantan protect people and bring a lot of benefits, however, whereas with no reclamation will the authorities reconsider these things? PRODUCTIVE WETLANDS: “Chiken waste from domestic industries and kitchen waste from cooking are composted to enrich the land fertilizer for growing vegetable and fruits. Sewage water feeds the orchards, vegetables and fish. After removing contaminants, this water used for growing rice and irrigation before coming back to rivers.” (interview, Studio fieldwork, 2015). This zero-waste cycle in rural Banjarmasin areas is experienced with sewage and waste composted farming system. This system currently is a very good experiment for our design being used by indigenous farmers, however, lack of technical support. This simple and ecological technique began simultaneously and has remained since then. The term of aquaculture makes use of wastewater from human and farming as a source for nutrients and warmer temperature to grow plants and fish. This is also used in the case of East Kolkata Wetlands (India) with the total areas of 3500 hectares which can produce 13000 tons fish and 150 tons vegetables per day. (source: www.dfid.stir.ac.uk/ dfid/nrsp/kolkata.htm.) DEVELOPING DESIGN STRATEGIES: According to the Provincial Plan 2008, Bajarmasin will double the population and fill up may parts with conrete surface. We want to adjust some details for the new development in the next 50 years. First of all is taking into account the wetlands’ ecology system as an extra rooms for water together with reducing urban footprint on swampy land. The constructed lagoons and wetlands should be placed in the first phase too, by which the authorities can manage the waste water for further develpment. Secondly, the saline defense is being raised as the second important step to protect the ecosystem inland and intensive productive activities. Decentralized the productive and industrial processing area is a part of the second phase to provide dynamic agri-aquaculture and enhance and preserve the peat bogs for wildlife culture and second saline defense. When all the big strategies of the machine are established, then the next are small interventions within various community can be implemented to strengthen the system where new coming urbanization can be protected on dryer land and decentralized within the landscape.

WET LANDSCAPE Although the integration between wetlands and public domain is neccessary and bring a huge and various benefits, how to apply them in the design is also a question for urban designer? For example, by reviewing the thoeries of landscape ecology principles, buffer zone is required between urban and nature, wet and dry, high land and low land to reduce the impact of one on each other. Wetlands is the one that has ‘in-between’ chracteristic to enhance the two identities. In addition to the edge theory, while the straight one encourages more pieces of movements long it, the convoluted one tends to have more movements crossing through. In this case we provide infiltration of movements in or just along the environment. Comparing to the straight edge which separates two areas aside, a curvilinear edge with tiny patches may provide a number of ecological benefits, including less soil erosion and greater wildlife usage.

WATER DISTRIBUTION

water source

Extra storage in peak events for emergency

The mechanism of cycle and exchange of waste , water and production between Cities and Wetlands can be showed in this scheme. This also shows the relation among different local stakeholders in water management. Normally, the system starts from the compact agencies (Riam Kanan DAM) provide clean water for downstreams. Plus, in the case of Banjar districts, we can have several small check dams benefiting for productive forest and chicken farming communities. These work as forested swamps storing more water in extreme wet season and reducing pressure on downstream. Then, clean water will be provided by feeder system (canals) to irrigation. On the city scale, there are different services working as drinking water supply, recycling service, purification service and compost service for better output water quality.

PRODUCTION CYCLE Rainwater run-off and water discarded after being used for a wide range of human activities; every city of the world must find a way of dealing with its wastewater, but it can be ca useful resources for municipal authorities, development agencies, farmers, fishers by wetlandsâ&#x20AC;&#x2122; treatment. As an exchange, productivity can increase by wetland management. According to the local production cycle through out a year, farmers can manage and mix crops due to wet and cry conditions, especially paddy and fish farming in which young paddy needs great amount of water in transplanting period and mid-growing period, in these period, fish can be growed together with rice and be more productive. In the same logic multi and mix crops can be cultivated on dryer land such as dyke system, which created a dynamic productive landscape in Banjar desa area. On regional scale, the exchange of production and water is much stronger as each area plays a role in the system. Wetland management leads to economic and ecological sustainability.

BUILDING RESILIENCE The urban water management challenges in South Asia are immense and will increase due to the predictd effects of climate change, disturbed terrain due to urbanization process and continuously rise in population. Todayâ&#x20AC;&#x2122;s world, many science and advanced technological implementation are applied to conquer natural forces. Yet, perhaps, ancient and indigenuous territories offers resources and efficiency to tackle the contemporay water management problems. In the case study of Banjarmasin, Wetlands and Gambut can, probably, be an efficient model to this. However, in fact, these ecologies are disappearing while large investment are being made to build new urbanization, contain water in pipe, embankment riverfronts and relaimation of intivesive plantation, especially plam plantation. But urbanization, agriculture and flood control are developed in different sectors giving contrdictory problems. There is the possibility for regional planning to take the soft engineering approach to work with nature. Vision for Banjar districtsâ&#x20AC;&#x2122; territories can build a resilient landscape which reconstructing the settlements 16

CONTEXT OF THE STUDY Many cities in the world, and especially in South-East Asia, are dealing with strong water conditions. Often heavily depending on river networks, they are currently facing issues such as flood, pollution, salination or drought. Attitudes toward water are changing with urban development and “live on, or next to, water” might become a renewed concept. South Kalimantan is one of the four provinces of Borneo island. The province is crossed by the mountain chains of Meratus, dividing the area into two distinct regions with different conditions. The western part of the province is mainly made of fertile lowlands such as marshlands, swamps and mangroves forests while the eastern part is mostly higher lands with agriculture and productive forests. People and traditions are a real mix of Javanese, Maduranese, Banjau, Bugenese, Chinese and Arabs cultures as Dayak, Malay and Javanese populations met with Arab and Persian traders 1. Most of the people live from agriculture, mining and trade. South Kalimantan is commonly named the Province of a Thousand Rivers due to its intense territorial water, both rivers and swamps. The main river of the province is the Barito, which is also the longest river of Indonesia (6,000 km) 2. In a context of islands, sea rhythms, such as tides, have crucial influences on the environment. Rivers like the Barito bring the tides into the land, creating variations of water levels and tidal swamplands with saline conditions. Various water types as well as different kinds of soil and profiles offer great and various economic opportunities for the region to develop. The water context of the province could be described as a superposition of surfaces, such as swamps, lakes or valleys, of lines, as the combination of natural rivers and man-made canals, and of crucial points, such as dams, junctions of systems and cities. This organisation interplays more or less efficiently and is the main element of landscape. Banjarmasin, capital of South Kalimantan, is located next to the region of Banjar, in the middle of the lowlands, on the Barito banks and is crossed by the Martapura river and a dozen canals. Subject to tidal influence, the proportions of water and land constantly evolve, punctuating inhabitants lives and changing territorial limits 3. The city has long been part of a culture of living with water either it is for economy, transport or daily lives. Located below sea level and due, among others, to environmental changes, the city needs to define a new relation with water and challenges the way to live with it. 1 http://www.borneo.com.au/bo00010.htm 2 SAIDY A., AZIS Y. “Sea Level Rise in South Kalimantan, Indonesia: An Economic Analysis of Adaptation Strategies in Agriculture” 3 KUSLJANSJAH K., SURIANSYAH Y. “The Innovation Of The Manufactured Floating House Model “

WATER CYCLES, WATER TYPES, ISSUES & OPPORTUNITIES 1_hydrological cycle

3_water issues and opportunities

Water is continuously circulating on the planet. Access and use of this water rely on the hydrological cycle and its management or preservation. The hydrologic cycle is the continuous transfer of water from one of the four storage site to another one. These four storage sites are: in the oceans, in the atmosphere as clouds and water vapour, on the land surface in lakes, ponds, streams and rivers, and underground as groundwater. To move from a storage area to another one, six solar-driven processes are recognised: evaporation, transpiration, precipitations, infiltration, runoff and base flow (through seepage) 1. In order to use the water, human interrupt the cycle in three ways: pumping from rivers, storage and pumping groundwater. Those actions can have negative effects such as water mining leading to withdrawal of groundwater and contamination of aquifer when waste water is released, affecting water sources both in the short and the long terms (quality and quantity). While a huge amount of water reaches the Earth surface, only a few percentage is suitable for human use. Among it, around 70% is used for agriculture purposes, 20% for industry and power generation and only 10% used for direct human consumption 2.

In the context of South Kalimantan, several issues related to water can be noticed. Among them, some are more related to natural phenomena while others are due to human activities. Salination affects water and soils located close to the sea and can lead to difficulties in terms of agriculture, farming and fisheries (even though specific plants and fishes can be raised in salt water) but mostly it decreases soil quality and makes it complicated to provide fresh and clean water. As consequences of current environmental concerns, sea levels are rising and seasons are disturbed and reinforced. Those conditions lead to threatened delta cities, coasts and ecosystems, to reinforce salination and to increase rains and droughts 4. Human activities for agriculture and urban development led to huge deforestation in South Kalimantan, increasing land erosion and sedimentation while decreasing water ground quantity and quality and protection of ecosystems 5. Another issue caused by human interventions is stuck water because of re-profiling land or of infrastructure. Those constructions might interrupt the way water has to flow to join the sea and lead to stagnant wetlands. Water withdrawal may cause the watershed to lose its ability to function as a purification system. However, even human activities might be affected as dried-out soil encourages salinity, erosion and water retention while pollution increases 6. Industries, agriculture, domestic life, fisheries and mining contaminate water creating polluted water and destroying natural balances. However, the nature and level of fresh water pollution strongly depends on socio-economic development 7. Human settlements on the banks of rivers also have effects on streams, reducing width of the river and polluting with waste. In addition to that, when banks are reinforced, water cannot find space to extend anymore, leading to stronger floods. Urban development also reduces infiltration by increasing impermeable areas and runoff water (as well as pollution). All those issues must be taken into account while managing water to develop opportunities and improve both quality life and economical aspects but also to preserve ecological dynamics. In fact, without doubt water and its abundance or its scarcity as well as its quality will define human well-being, environmental sustainability and economic activities 8.

2_multiple types of water Back in time, water was mainly used for daily needs and transportation. Overtime, sedentary populations developed and increased their needs of water, developing technologies to divert water for irrigation, domestic purposes or transport 3. Water can be available under various forms such as salt water, fresh water, surface water, groundwater, black and grey waters or drinkable water. Following water quality and uses, water can be more or less treated to reach clean water standards, fresh water levels or less polluted conditions. 1 WAPAC “The Economic, Social, and Environmental Impacts of Water Use in Rhode Island” 2 UNEP “Towards a Green Economy: Pathways to Sustainable Development and Poverty Eradication” 3 FAO Agriculture Series “The state of food and agriculture” 8

The notion of sustainability, which must be taken into account in today’s reflexions, can be approached from a three-ways relationship between nature, people and economy. In fact, current landscapes are made of both natural systems, such as hydrology, airflow, climate, vegetation or topography, and human settlement, such as urban development, infrastructures, productive areas, etc. In addition to those two elements, a third one can be added: human organisations. In fact, culture, social relations, politics or even economic environments shape landscape and influence territorial design 1. Those three approaches to sustainable development were brought to light by Munasinghe. “The economic view is geared towards improving human welfare, primarily through increases in the consumption of goods and services. The environmental domain focuses on protection of the integrity and resilience of ecological systems. The social domain emphasizes the enrichment of human relationships and achievement of individual and group aspirations. The interactions among domains (represented by the sides) are also important to ensure balanced assessment of trade-offs and synergies that might exist among the three dimensions. Issues like poverty may be placed in the centre of the triangle to re-emphasize that they are linked to all three dimensions” 2. Each one of those aspects has its own forces and objectives but a balance between them must be found in order to integrate sustainability into the reflexion 3. In every context, we can find those three aspects but in various proportions. While talking about water management, economy is often the most developed axe, sometimes to the detriment of ecological values and social aspects of water, probably because it is the value that brings the most advantages of development in people’s perspective. However, water is vital in three ways: “it is an asset essential for life and a common good for human well-being, it is a production factor and economic asset essential for economic prosperity, and, integrating these two, it is a vital environmental asset essential for the maintenance and regulation of the ecosystem services that ensure the long-term sustainable provision of the economic and social goods and services on which prosperity depends” 4. Water is one of the most crucial natural elements that create the landscape. And, as we saw, it is way more than landscape. This is even more true in the context of South East Asia and South Kalimantan where water imposes its rythms.

2_ecological aspect The ecological aspect of sustainable development should maintain resilience and robustness of biological and physical systems. Fresh water is a vital resource to humans, animals and plants health both in aquatic and land based systems. Unfortunately, this aspect of water is rarely taken into account while organising economical assets for further development. Water provides habitat for fauna and flora but it also transports nutriment that can feed other ecosystems while it can influence climate and generate insitu benefits 5. Natural environment is a clever balance between various ecosystems that need to be protected. Some of them strongly depend on water while others use it as an irreplaceable contribution supply. Protecting the natural ecosystems of river basins and restoring degraded catchment areas is crucial to secure the world’s water supplies, maintain their quality, regulate floods and mitigate climate change 6 . Considering water as an ecological asset brings the fact that water is made of flows that keep running. Everything is about movement and at the same time water does not stop flowing. The question of water as a renewable resource or not is brought on the table. The notion of water cannot go without the aspect of evolution. Due to tides, seasons and uses, water levels, withdrawals and floods constantly modify the shape of the region, giving rhythms to the landscape and to people lives. 5 GLEICK P., WOLFF G. “The New Economy of Water : The Risks and Benefits of Globalization and Privatization of Fresh Water” 6 UNEP “Towards a Green Economy: Pathways to Sustainable Development and Poverty Eradication” 9

3_social aspect The social aspect of the triangle of sustainability must maintain stability of cultural and social systems. Individual well-being as well as the overall social welfare are both refering to the notion of social development and bring a higher level of civilization for all members of the society 7. Widespread availability of clean and accessible water is a social good in the sense that everyone should have access to it within affordable conditions. However, value of water may significantly change to people according to their cultures, social conditions and needs. However, social aspect also refers to the respect of traditions and cultures that represent people identities, water playing an important symbolic role. Strategies should be designed based on an analysis of the social aspect such as history of the civilization, society organisation, traditions, religions, moral and behaviours in combination with the spirit of the place (notion of genius loci) 8. Water is a support for, among others species, humans. Fresh water and clean water have often been controlled and canalised to offer supply to urban development. As well, grey and black waters are (or should be) collected in order to be cleaned before being reintroduced in the hydrological cycle. Those man-made networks support human life within their environment and should be implemented while keeping in mind economical but mostly ecological challenges. This form of water privatization, from a free public good to a private water service that you need to pay for (even with low rates), brings the questions of stakeholders and investments that connect social aspects and economical issues of development. Talking about the social aspect of water brings new ways of considering water as well. In fact, water, as rivers, wetlands and lakes, can be considered as a place in itself, especially in the context of South East Asia. It can become a place to use as a network for transportation for example. Transportation that becomes useful for economic reasons and daily opportunities as well. But it can also be used a space to live and to share while considering how people use riverbanks as settlement areas. Types of floating houses, public spaces on and next to water and water villages, such as Kampungs for example, were developed since ancient times and are adapted to evolution of uses and habits.

Protect, flows, evolve, live, share, move, grow, produce, trade

4_economical aspect From an economical point of view, it is crucial to maximise incomes while maintaining a constant, or increasing, stock of capital. Most of water uses have an economic value, either it is clean water for daily purposes or fresh water to irrigate agriculture fields or space for markets and trade or a tool for industries 9. Water is an economic good but the question of governing it by rules of market may lead to issues of equal and affordable access to a social good and human right 10. In addition to the character of economic good, water has a strong spatial economic aspect since it can also be used as a space. A space to grow fishes, agriculture and aquaculture goods, a space to produce products like wood for stilts or energy and a space to trade, at various scales such as from the small village floating market to the international port and harbour. Water and its uses connect stakeholders from the individual user to the big industries and companies together with politicians and municipalities. Various scales and sectors, public and private, need to work with each other, in order to balance power for the common interest of further welfare and growth 11.

5_in the context of Banjar region Water connects. It connects economic interests together, it connects regions, cultures and even opinions 12. In South Kalimantan context, landscapes are mainly made of the outstanding character of the structure of the water body, artificial and natural, and human uses of it. Each city and context has its own view of development and proportions of nature, people and profit. For example, some historical cities might have development plan based on the cultural and traditional assets of their region even if it is not always the most effective way economically speaking. Some other regions can be developed by paying particular attention on the green and blue structures or by looking for the most cost efficient approach while decreasing quality of life for users and inhabitants. In Banjarmasin and Banjar region, they seem to try to develop further and further the economy, at every scales but without really considering people and their well-being and most certainly, without regarding water issues. People are daily subject to flood, do not always have supply of clean water and often aren’t connected to sewage systems, spreading diseases and pollution. Within this context, water can become a crucial tool or a devastating element. As a matter of fact and as a result, relationship with water seems more and more complicated and leads to stronger problems of flood, drought and water quality while for centuries people have chosen to live on this context where they have to deal with water, either it is a threat or a blessing. Ideally, the three elements should be balanced within every project. Unfortunately, it is not always possible. Some projects conditions and actors may lead to develop one of the aspect more than the others, which is not an issue as long as within each scale and all the interventions, a balance is kept and ensures sustainable development for the nature, the economy and the society.

2_ways to live in South Kalimantan

Culture is a vague concept. Anthropologically speaking, we could quickly define it as all practices, uses and habits of a civilization. Culture concerns many various fields and spatial organisation of the space and the society is one of them. Architecture and the relation with the physical environment reflects the way of thinking and people’s personality as well as their relation with nature. Following Rapoport classification (2005), culture can be seen as an arrangement of room, time, meaning and communication, a background system, a cultural landscape or a configuration of permanent elements (infrastructures, wall, roof, foundations,etc) and semi permanent elements (building, interiors finishing) together with nonpermanent elements (human, behaviours, clothing, animals and plants). According to Altman and Cherner in 1984, they classified five important factors that link culture and environment and show their association: natural environment, environment orientation and way of life, environment cognition, environment behaviour and environment as final product. In addition to this culture-environment relation, the expression and shapes of built environment is influenced by three aspects that are its function, its structure and its culture. “To understand culture in built environment more easily, Rapoport dismantled culture vertically and horizontally. Vertically, culture can be elaborated into tangible social expression with potential for observations; this includes kinship, family structure, social role, social network, status, identity, institutional, etc. Horizontally, culture can be explained into life philosophy such as values. These values are divided into two, first is about ideals, images, scheme, meaning, etc; second is about way of life and activity system” 1.

The people living in South Kalimantan are called the Banjarese. They are a the descendants of mixed cultures such as the Dayaks, the Javanese and the Malay. Most of people rely on farming and fishing for their daily needs and incomes. Farming concerns more specifically plantations and crops that are grown both for local use and exportation. Fishing produces different kinds of fishes following environment and supply in water (saltwater, freshwater, runoff water, etc). In farming and fishing, water conditions, both in dry and wet seasons, is a crucial element that defines more than what people can produce. It defines people life conditions and economic development. Social life can be represented by the term “jam karet” that can be translated as “time that stretches like rubber”. Banjarese prefer to take moments as they come instead of planning everything. Meeting each other and taking the time to share is really important in the social life of Banjarese, in addition to praying times related to their Islamic believes. Family is a strong organisation in Indonesia. The concept of extended family is extremely frequent. Often, family members live really close to each other, if not in the same big house. By member of a family, we mean more than two parents and their children but grand parents, aunts, uncles, cousins and so on. Most of children will go to school while some of them will have to help with farming and fishing. Elders are highly respected for their advices and experience of life 2. Houses and villages are often organised along a main axe with small shops, schools and mosque, either a river or now a road. Houses are located by families, children building their house next to the one of their parents. There are eleven different kinds of houses in South Kalimantan. The most common ones are the long houses, that are more than 100m long where several families live together, and the lanting houses as semi (or completely) floating houses, adapting to water levels or traditional houses on stilts. Factors like local natural condition, disposable natural resources, human organization and local culture, influence housing that is adapted to the environment 3. Banjarese have always been close to the river. Daily community activities take advantage of the presence of rivers, including economic purposes such as trading, social interaction and as the main transport route before the land transportation such as we can recognise a water based culture 4.

TO CURRENT ORGANIZATION 3_shifts in waterscape, urbanscape and socialscape

4_evolution of living on the water

Back in time, water was the decisive condition for settlements. It allowed to connect points of interest while serving to produce food and goods and support daily needs. The system of rivers shaped the entire region, from the foothills to the wetlands and the forests 5. During the Dutch colonization and looking for improvement in water management for irrigation, water supply, transport and productivity, men-made canals systems were built, leading to a network made of a combination of a natural and an artificial grids. Around the 1970’s, a system of roads was put in place by landfill (covering existing canals and marshlands), reducing width of water network and slowly replacing the role of river as structuring axe. Transport became faster, new kinds of business were born and activities and urban development shifted from water based to road based landscape 6. Socially speaking there are also some changes. Education is consequently improving, leading to higher jobs and new ways of thinking, challenging current and traditional lifestyles 7. More and more people are moving to cities which are already pretty crowded, questioning quality of life. Traditional lifestyle are being threatened by big corporate companies like mining or palm oil productions. In addition to this, tourism is more and more developed, offering new opportunities of development. The city and its region are shifting from a water culture to a land culture 8. Anyway, water is still there and those human interventions changed its natural flow creating advantages and problems at the same time. Municipalities still have opportunities to develop new ways of living with water through further developments. Besides, recently, the way we think about water has begun to change. Around the world, water scarcity and shortages will increase in the future, failing at meeting human needs and leading to more and more tensions around water supply. Therefore, large water infrastructure built and operated by governments was considered vital for national security, economic prosperity, and agricultural survival 9.

Houses reflect human needs and organization. It is expected to evolve as society and environment, to illustrate the evolution through life requirements and transformation of the context and its surroundings. A few decades ago, most of the settlements on the delta of the Barito river used to be built next and on the water as stilts and floating houses, as a response to water fluctuations. “Floating houses are the architecture capable of floating in the water and maintaining a functional floor height above the water surface when exposed to high tide or flood. Kalimantan floating houses models are known as lanting houses, that is a traditional raft house the Banjarese in South Kalimantan with a floating rafts foundation built on a structured arrangement of large trees trunks, and always locked by waves from ships going up and down the river” 10. Three reasons seem to explain the development of lanting houses, called Rumal Lanting. Banjarese community needed a moveable housing to accommodate their occupation. By its construction, lanting house is portable and can be moved following job needs. River is the main transport mode and people sell their products by the river, using lanting as a store to get near their customers. And people from Hulu Sungai who are traders using rivers came with their lanting houses to settle in preferable place to live and trade 11. Lanting houses were based on a simple rectangular plan, positioned lengthwise to the river. Houses were fronting the rivers and canals since it was the space for economic, social and transport activities. Front doors were facing the water through a series of platforms joining the water 12. Those platforms were used as a space to park the boats, to produce goods but also as an area for sales and trade since houses were often associated with shop. A small wooden bridge used to connect houses with the land and was used as a washing area, testifying that back then, the land side of the house was considered as the backside.

Since the roads were built and then modernized, houses started to face them instead of the river. Domestic activities, kitchen and toilets are on the river side of the house while the social and economic aspects are connected with the new axes of roads, minimizing spatially the role of water. Rivers are now used mainly as drainage and accommodate waste disposal, even if some transportation still remains while the decks are not even always built anymore. Today people still living on the river are either the one that could not find a landed house or could not afford it either the ones who’s job is still strongly connected to water. Strong family links can also influence people implantation. Nowadays, traditional lanting houses need to be protected and could be developed as a tourist asset for the region 13. Those houses are the transition between water and land, playing the difficult role of waterfront. This transition adaptations were meaningful of a true consideration of the local culture and environment, expressing the physical form of Banjarese river culture, architecturally, socially and historically 14. Floating houses have this incredible advantage that they are adapted to the water environment and could be adapted to current issues to live with water.

Relation between water and lanting houses

Water management as a tool to improve The relation between water and people is as old as human society. Human have been trying to change nature by controlling water running through landscape. Those “implementations” lead to crucial changes in the way water was joining the sea while trying to deal with flood, dams, canals for irrigations or river for transportation. “Dams have stored, regulated and raised water. Watersheds have been reworked and linked. Rivers have been forced between levees and dykes, canalized, straightened and cemented. Water has been diverted from areas of water surplus to areas of water deficit. Lakes have been lowered and wetlands drained and the artificial river is definitely not a modern invention” 15. Water availability and opportunities to manage it are affected by the fact that water flows in complex ways. However, understanding those streams is crucial in order to provide a sustainable development 16. The different kinds of water should be managed together as a fragile resource to enhance public spaces, revitalize neighbourhoods, strengthen habitats and provide opportunities for economic growth 17. Slowing down water and store it are two main actions while talking about sustainable water management. In fact, by slowing it down and storing it, infiltration, evaporation, habitat and uses are increased while erosion of the land and sedimentation decrease. Circulate and recharge water systems both in surface and in the ground allow to improve quality of water and quantity as well as it reinforce the region’s ecological health. In any event, Nature already applies those principles. Artificial processes can help and enhance those actions to facilitate relationship between Nature and humans. However it is crucial to keep in mind that landscape, waterscape and urbanscape are dynamics patterns. In fact, changes should be designed to support diverse uses while keeping in mind that water knows no political boundaries 18. In order to fit to the triangle of sustainable development, water management should also support economic growth. It is time to strengthen regional identities and consider water at every scales, not only the city scale anymore. Water is part of a watershed that needs to be considered in its entirety in order to adapt the most efficient tools. Sometimes, smaller scales intervention will adapt easier to the environment and allow people to appropriate them on a local scale while often reducing costs 19.

“It is important to study both the unnatural and natural history of water disasters, since not only will floods vary and have different causes and consequences but fundamental concepts like flood, drought, water shortage and water conflicts have different meanings and connotations in different physical and social settings” 20. Indeed, two challenging issues need to be studied to adapt future development: implementation of local policies to guide spatial and urban growth on a macro scale and on a micro scale, architectural and spatial innovations to live with water 21. There are probably no one-shot strategies to solve water issues. According to the context (environmental, social, political, historical), specifics set of mixed tools and solutions can be elaborated. Water is clearly fundamental to food production and vital for industrial production and energy generation and in addition, accesses to clean water and sanitation is crucial for every household 22. Water is a natural element needed for life. But water is also a central element in the organisation and appropriation of space, collectively but individually as well by being of functional use. Social relations and economic development are heavily influenced by the presence of water, as History of cities implantations can tell. However, relationship between people, cities and water are simultaneously moving and uncertain. Water is a positive and negative element at the same time. To deal with the negative effects of water and improve its uses water has been more and more controlled using canals, dikes, dams or reinforced banks. While improving quality life near those interventions, natural flows are modified, increasing risks of more issues in other regions. Modern way of life is challenging the identity of Banjarmasin and its surroundings. Transformation of urbanscape and environment is influenced by both natural and artificial conditions and actors. We need design strategies capable of intervening into the contemporary city, dealing at the same time with socio-cultural, environmental and ecological issues 23. Water is a fact of life on the delta. We can allow it to become an asset for the region by making space for it while making it visible across the urban landscape. This way, we create a possibility of cohabitation between people and water in a sustainable development.

Introduction The Mining sector has become an integral part of Banajr Bakula,Indonesia, as it is a significant source of foreign exchage, economic activity and regional development. The booming of the mining industry has contributed to the increase of over a hundred working mines in the country in the recent years and created opportunity for new employment. But mining industry has negative impacts on environment such as soil, air, water pollution; habitats fragmentation which play a cumbersome role in the process of forming new ecologies in post-mining landscapes. The level of irreversible damage is fast approaching requiring a strategy that takes into account the need for future growth since the population is expected to be doubled and the threat increases with the passage of time. Instead of rejecting the obvious future urban sprawl the idea is to ensure a systematic growth and balanced coexistence of urban growth, ecology, public facilities and services and production in both food and economy. These understanding

mining scars...active-inactive mines, excavation

come up with the case study of mining area of Banjarbakula, Indonesia and in the thesis I try to outline the vision for a better role for the acceptance of new after mine closure preserving the essence of the unique landscape. This thesis attempts firstly to examine mining industry near Banjarbaru area in Banjarbakula regionthe and acknowledging the problems of post mining condition try to explore the opportunities in the post-mining landscape. Post mining landscape with larger volumes of soil, large quantity of contaminated-water, mounds of dust, the open-pitsand-dumps-undulated-surface are the problems which are usually seen as problems or scars in landscape have possibilities to be transformed to be potentials. Some proposal emphasizes the eminent build ability of mining lands whereas other preference is to consider its dynamic open space potential serving the purpose of preserving the vast open space which otherwise would most probably have been consumed

Methodology The study was done in inductive approach.This study has been started with visiting site to see the mine-closure and post-mining landscape and understand the reality, to collect information and taking interview of the community people and related actors in Banjarbakula, Indonesia. The process is followed by Developing interpretive map, designing and discussing in studio about the vision and the strategy in regenerating the postmining landscape. literature-study has been done in all stages of analyzing, designing and finally writing process of the thesis.

Historical development of mining in Banjar Bakula, Indonesia

exploration sprawls beyond the cempaka village and spread over along the areas of Sungai Tiung, Bangkal village, Palam village and Pumpung village. The pasar Martapura itself then becomes the biggest centre of diamond and gems transactions; covering not only the local transactions but also worldwide including the export its diamond production to Antwerp’s diamond network. Exploitation by a big foreign mining company has created huge environmental pollution and destruction on these villages and the local traditional miners are also banned by the company to do mining activities in their own villages that are occupied by these companies. The immediate neighborhoods and local environmental NGOs protested against this mining company after a huge pollution emerged along the rivers next to the excavation site in 2008 (kompas, 10 April 2008). As a reaction the province government of Kalsel declared temporary closure of the mining activities of this company until they are agree to provide production system that are safe for environment and also willing incorporate the local miners.

In Indonesia Small Scale Mining essentially consists of four major sectors: gold mining,diamond mining, coal mining,tin mining.But in the thesis as a part of design studio I investigated the mining site within the study area in Bnajarbaru which consists of mainly gems and some excavation mining. Diamond and gems’ mining exploitation in Martapura-Banjar - Banjarbaru area have begun since 9 A.D. Cempaka village, located at the area of Martapura and Banjarbaru. was the central area of excavation. The Martapura area has became well-known for diamond production since the Dutch colonisation and in nowadays it is one the biggest site of diamond mining in southeast Asian region. During the Japanese colonisation in 1942-1945 the mining site of the Dutch in Cempaka was taken over and local people were forced to excavate diamond and gems in their traditional way and collected them in their warehouses. By the end of this Japanese era pasar Martapura emerged as the site where the diamond and gems’ transactions and collections between the Japanese authority and the traditional miners took place.

Character and context of mining site

The big scale of diamond and gems mining company was stopped after the independence of Indonesia in 1945. But it started to boom again from 1960 after one 166,7 carat of diamond; wellknown as Trisakti Diamond was found in the northeastern area of Banjarbaru. Since then until today; the traditional mining

Two types of mines are found in Banjarbakula: excavation and gem stone mines. Some landscape are active with continuing mining and some inactive mine are now in the post mining phase of landscape.Excavation mines are usually connected to road infrastructure and gem stone mines are linked with the water

Recently the gems excavation has begun to boom again in Banjarbakula after a 200 carat of diamond; well-known as Putri Malu diamond; in Antaraku village at Banjar area is found by a traditional miner (Kompas, 8 February 2015). As a result, the local traditional gems’ mining is now growing again in a more alarming scale in Banjarbakula area since this is been known as one of the main production sites of gems.

system. Excavation and gems mines can be categorized into compact porous of nature respectively. For purpose of detail analysis six mining zone have been selected as representative of different mine within the study area. Near the town of Cempaka the mines have been slowly moved as old workings have been worn-out. Mining has become more difficult now than in the past because the upper gem-bearing gravels have been worked out extensively. The gem-bearing gravels can be found 10 m below the surface of the swamp, with the water table lying just underground. In South Kalimantan small-scale artisanal mining are still continuing but Borneo is no longer considered a significant source for diamonds. The primary diamond-producing areas in this region are to the west of Riam Kanan Lake in the south, and the Upper Barito, Sungai Lahung, and Gula areas in Central Kalimantan. Martapura is known as the “City of Diamonds” and the villages of Lukaas and Sungai Tiung in Cempaka are a primary source for diamonds in South Kalimantan. Indigenous miners in this region still depended on this mining activity in gravels and muddy sediments. “Black diamonds,” “colorless” which are rare collection are found in South Kalimantan. Lower-quality yellow diamonds known as “petrous”, and “pink diamonds” with a high brilliance are also found in this area. (Gemstone Industry in South Kalimantan, 2015)

Nine big companies control the stone quarry and they also employ the local people for working in the quarry sites. The locals can buy the excavated stones to break them into small pieces and sell them to construction industries through some agencies. The households around these mining sites are mostly depended on the mining activities for their living. The miners now usually work together in a communal mining association. The women are part of this industry with involvment in every element of the work except the strenuous lifting of equipment. The post mining sites are threatened by different forces like QUARRY influencing water buffer capacityand and higher erosion, growth, monofunctional urban sprawl, unplanned commercial industrial vastcommunity big companies in harmony with the community cash crop plantation i.e. rubber and palm oil plantation. 10

Post mining desolated landscape and challenges

Abandoned industrial sites have always been responsible for environmental problems. Mining activities can be considered a special type of industrial site and these are well known by their harmful effects on the environment. Environmental impacts range from water pollution, noise pollution, air pollution in the form of airborne dust and the sterilization of productive land and so on. Environmental issues related to gem industry are mainly soil erosion and sedimentation, destruction of river banks, ground water depletion and pollution of surface water bodies, causing damage to the public and the private property etc. Due to poor management and neglect tailings dams have been subjected to varying degrees of water and wind erosion. Acid mine drainage generated from underground mining operations are the primary reason for the contamination of water. The stone quarrying activities initiate deforestation, and thus influence the water balance, the erosion of soil and sedimentation in the river system.

For the mineral close to the surface where the mineral itself is part of the surface soil or rock, surface mining methods are often considered as more economical. Disruption of the surface has significantly affected the soil, fauna, flora and surface water leaving the area as barren land. The ecological habitat has been destroyed by the extensive dredging operations. Large amounts of waste are produced in the process. Post-mining landscape has created many other challenges in Banjarbakula region such as abandoned mines-voids, series of formatted open-pits and dumps creating undulating landscape, large quantity of stored water, mounds dust, contaminated soil. Together with the general environmental problem Banjarbakula is struggling with socio-econimical issues as post mining effect such as unemployment, abandoned mining camp/ hostels and industry Platform and other infrastructure, survival and health related problem of humans, plants and animals due to the toxic landscape, huge cost for remediation of the disturbed landscape and searching for new urban identity.

UNSOLVED SCENARIO 13

Sculpting the mining landscape

From scars to identity

The area around the mining sites in Banjarbaru has good soil condition and Banjarbaru would be centre for new government provincial the investigated area is most promising to welcome the projected future growth of Banjarmasin. The main strategy is to keep the mines as structuring void for new so that it is not lost in time under pressure of development or negligence and preserve the dramatic post mining landscape safely for future generation as â&#x20AC;&#x2DC;history landscapeâ&#x20AC;&#x2122;. Since no one can predict the exact future growth, this is an open ended story, instead of detail planning/solution for each side a system has been proposed that can accommodate uncertain future. Ecological driven scenario, Development driven scenario, Optimum growth scenario can be visualized. In the Ecological driven scenario ecology serves as framework for guiding the future development whereas in development driven scenario transportation and social infrastructure like school, mosques are the initiator/ guidance. The optimum scenario would be where urban growth develop/co-exist with ecology in a balanced way Regardless the scenario in every cases mining scars/site should remain as a unique landscape. These should not be seen as barren land from where valuable things/minerals are taken out leaving the desolated landscape but also appreciated as new terrain which open a door for new experience, new opportunity.

mines as the structuring void for the new

In the starting of the planning strategy of the post-mining landscape some things should be kept in mind, like what elements should be retained? What should be transformed? What should be added? and what should be reprocessed? Introduction of human related systems, consideration of long term economic generators and long term system development has been included in different phases.

ecological driven scenario 16

There are several options to transform the apparently unusable post-mining landscape to the potential trajectory. The opportunities varies according to specific post-mining landscape condition, is highly dependent on the site and context, level of damage etc. Some mining sites are more appropriate for ecological facilities like retention pond for flood protection, agriculture, food production, diverse aquaculture, reforestation and some are best suited to absorb future growth, services and facilities for future growth, public space, mixed use development depending their character and location in Bnajarbaru These desolated landscapes can be transformed into potential sites that can act as attractor, void, absorber while keeping the unique landscape of old mine system. To implement this strategy post mining operation for all the mines focuses on three general steps. The first step is the remediation and purification, the next step is to guide the future through grey, green infrastructures. The final step is to obtain diversification and matured landscapes depending on the context and types of mines. Environmental protection The main concern for post mining trajectory is the reintroduction of local flora and fauna while retaining as much of the mining landscape as possible. Remediation and purification can be done using water purifying plants. For stabilizing the mine dumps from water and wind erosion different methods have been experimented and vegetation cover is proved to be the most documented and mostly widely used method. The proper selection of plant species that will grow, spread and thrive under the hostile conditions provided by the nature of dump material is very crucial for the successful establishment of vegetative cover. Local plant species like Rubber, rambutan, Ficus, Ulin can be planted in Banjarbaru area as remediation and reclamation.

character of mines 18

The tailings dams are quartzitic (siliceous) and generate acid on the surface and lack organic nutrients for plants to grow and are thus totally unsuitable for vegetation growth. So the revegetation of tailings dams requires some preparatory measures prior to vegetating which include altering these conditions by using methods such as liming and leaching. (Mphephu) Reforestation and selective cutting is proposed in forest area near Query and to support this building community training center ,wood processing industry can be a wise strategy

This will also serve as a breathing park, social nodes Mines as structuring voidsthat fordrive the people to gather, meet in the future dense urbanized scenario which are lacked in present Banjarmasin area. This will allow people to access by walking, cycling to the mine legacy showing the remediation process.

new

Starting with the preservation of the landscape created by the mining different functional activities and services will be added to the site as time progresses, benefiting the surrounding communities and increasing economic generation of the site. These can include industry, commercial, mixed used development, educational facilities, recreational facilities, horticulture and varied research center for exploration and investigation of Reclaimed landscape and tailing ponds. The mine near the Banjarbaru is a potential location for constructing future educational facilities like university campus, infrastructure for sports facilities considering the soil map and their proximity to the center of the city.

Post-mining infrastructure can be reused with another functions being a part of landscape components that has the strong relationship with natural elements like pedestrian trail, bicycle path. It is envisioned that recreational uses unique to the sites conditions will be very useful and successful public space. The haul road in Query mine has the scope to be develop as a topographically diverse biking trail for various modes of recreation (hikers, bikers, and vehicles).The unique reclamation design of the haul road can transform the mine site into a major mountain-biking destination enabling visitors to experience a part of history.

High density + student housing typologies as border/threshhold

Economical prosperity The pumped and treated water can be used as resources that can generates some economic activities , i.e. water irrigation system for watering the urban agriculture, community garden, fish production for the people and the city. After remediation food production on and around the mining sites will help to meet the increasing demand for food as well as earn money by exporting this product.Operational Wastes can be used as Resource for New Businesses, in some instances these can substitute the river sand as an input to cementatious building aggregate. Involving the local people in the reclamation process will address the problem of unemployment.

High density social housing, student block can be built near the periphery to protect/ stop/control the urban sprawl over/ on the mining site. Waterways/ canal, topography can also be used as elements as barrier/border.Because of the good soil condition it is possible to build higher than the existing building on the land near Banjarbaru which will accommodate more people occupying less area.

Conclusion Strategies for post mining landscape should respond the changing social expectation, economic fluctuations, and political instability..The miners of today have a responsibility to produce minerals and metals following the law and restrictions so that they meet the needs of he present without compromising the ability of future generations to meet their own needs. Recreation, reclamation, and the generation of new ecological habitats are possible and capable of coexisting with a mined landscape.This project positions as a possible set of opportunites for achieving an ecologically and economically sufficient landscape which is also a part of history. Not only cleaning up the contaminated lands, but also incorporating reuse planning in the cleanup process should be considered in the strategy Participatory approaches to post mining revitalization have shifted from focusing on the mere cleanup of contaminated lands to ensuring their cleanup with beneficial and productive reuse plan. Screening on the future vision of Banajarmasin and surrounding areas that will try to put the focus of the urban expansion and the conservation requirements, considering the expectations from local community, mining associated people developing agriculture as the economic In the future of 50 years, after mining closure, most of the post-mining area can be proved to be a successful receptive landscape to absorb new growth and scenarios.

ROOTED IN THE LANDSCAPE

Regenerating Mangroves as a Framework for Future Urbanity - A case study of Banjarmasin WATER URBANISM STUDIO 2015 _ Thesis paper by Joyce Stijnen

1_A landscape under pressure The city of Banjarmasin will undergo dramatic transformations in the following years: the city is planning a new additional port southwards, the former river-based city will be changed into a road-based one, a regional railway line will be introduced and Banjarmasin is expected to double its population by 2030. (1) A handful of factors that put an enormous pressure on the area which will be craving for housing, work opportunity, food supply ... The city is rapidly encroaching upon the territory, taking over rivers, paddy fields, forest, swamp, mangrove, ... There is no specific plan to guide this development and important ecosystems lose ground. One of these ecosystems are the mangroves: salt-tolerant, intertidal forests that grow along riverbanks and coastal areas. (1) Not very long ago, the city of Banjarmasin was surrounded by mangrove forest as we can see on a map of 1945. (image 1) In less than a century almost all the mangroves have been replaced by rice paddy, development, port area, fishponds, infrastructure, ... If this trend of land use will continue there will be no mangrove left and the consequences will possibly be catastrophic. Therefore things need to be turned around. Can there be a coexistence of mangrove forest and future growth? And how can we return to Banjarmasinâ&#x20AC;&#x2122;s natural landscape where mangroves play a leading role mediating between water and land? Can mangroves be introduced as frameworks, guidelines where the new port area, railway line and the increasing population can find their way through? To be able to measure the consequences of mangrove loss it is important to understand the importance of the forest on diverse scales: the local importance to traditional settlements, on the scale of the country for its economy and on a worldwide scale addressing climate change. < Image 1: Historical map from 1946 showing intertidal mud flats and mangrove areas in blue. (Source: Landsarchief Batavia.)

2_Productiveness and protectiveness Natural breakwaters

Indonesia gives home to 1/4 of the world’s remaining mangrove forest which is still declining by 1-2% every year. Studies in 2009 reported that 30,7% of Indonesia’s mangroves were in good condition, 27,4% moderately destroyed and 41,9% heavily destroyed.(2) All these numbers may not visualize the problem but catastrophes like the tsunamis of December 26th 2004 around the province of Aceh certainly do. Although the tsunami was a natural disaster that could not have been foreseen, the high death toll could have been much lower. According to Quarto1 the greed and short-sightedness of man resulted in the clearing of the natural buffer zones which have historically been barriers against wind and waves and are widely considered as the backbone of tropical coastlines. (3) In India mangroves have proven their protective capacity in 1999 when a super cyclone struck the coast of Orissa. This super cyclone caused death to 10.000 people and 7 million people were left homeless. The most affected areas were located where shrimp ponds, port facilities, ... had replaced the mangroves. In areas where mangroves were left undisturbed (Bhitarakanika in Orissa), villages were secured by the natural buffer. (7)

Growing land

Next to the ability of providing a protective dike against forces of nature, the mangroves stabilize the ground with its extensive root network and thus prevent abrasion (coastal erosion). The mangroves are also able to adapt to sea level rise by colonizing landward zones and growing into seaward areas. Mangroves can survive in between the mean sea level and the high tide level. When the sea level rises; more land will become sea thus the lateral accommodation space2 increases. Therefore mangrove forests are referred to as land creators. (image 3) 1

In a report of The Nature Conservancy, Wetlands International and the Cambridge Coastal Research Unit in 2013, a broad range of existing evidence (historical and current) were reviewed by scientists and they found out that mangroves are able to build up soil at a rate of 1-10 mm a year. For many areas this is well within the current 3 mm sea level rise per year. The rate of 1-10mm is very dependent on various factors: sediment deposition, erosion, root growth, mangrove species, decomposition and more. How all these factors are intertwined is a very complex manner that needs more data over the next years. “We are just beginning to develop this picture. It seems that mangroves won’t keep up with seal level rise in all locations but there’s also tantalizing evidences that we might be able to manage mangroves to help the process.” says Mark Spalding, senior marine scientist and co-author of the report. (6)

Flood control and hydrological regulator

The sturdy trunks of mangroves (image 4) are able to reduce the velocity of water flow when heavy rain arises. An additional instrument that mangroves use to mitigate in flood hazards is by absorbing water in its substrate. Mangrove can also play an important role in reducing the intrusion of seawater into the land: by preserving terrestrial fresh groundwater levels on one hand and preventing tidal waves from reaching rivers, on the other. Mangrove is capable to survive in high saline areas where other flora fail to do so. The trees can adapt by absorbing salt into its roots and leaves, this way they also again contribute to the reduction of water salinity in the environment. (5)

Livelihoods and economic potential

Mangroves are characterized by their shallow inter-tidal reaches that offer a comfortable place for various fauna to take refuge in and provide the perfect nursery grounds for young shrimp, oysters, fish and crabs.

Co-Founder and Executive Director of the Mangrove Action Project (MAP) which began in 1992. MAP is an international network involving over 450 NGOs and 250 scientists worldwide,

who are dedicated to coastal resource issues, including mangrove protection and sustainable coastal development.

The forest is further a perfect breeding place for hundreds of bird species. Also monkeys, manatees, lizards and turtles make use of the wetland. (3) Traditionally mangroves have been sustainably managed by local settlements. They utilize the mangroves for its fruit, vegetables, fish capture, medicinal plants, resin, fire wood and constructing materials. The forests offer a dependable source for livelihood, direct food supply for own use and make it possible to preserve their traditions. (5) Mangrove is known as the ecosystem that has the highest productive capacity. Most of its productivity is derived from leaf-fall which can be 3 ton of dry weight every year for Indonesia alone. The fallen leaves produce very fertile waters which make fishery productivity in and along mangroves very high. (5) This blend of the two is very beneficiary: the fish ponds become very fertile and the mangrove controls and absorbs waste nutrients that are created by the ponds while protecting the ponds from forces of nature. Timber is also a direct benefit derived from the mangrove forests. Although its high timber potential, it is not as lucrative as other types of forest due to its smaller coverage in area and the number of commercial species that is considerably lower. The timber products for which the mangrove forest are used are: wooden planks and plywood, scaffold, charcoal, building material, poles and firewood. (5)

Carbon sink and biodiversity

Mangrove originate from the Indo-Malayan3 region. This is why we can find the highest amount of mangrove species here. There are 45 species of the worldâ&#x20AC;&#x2122;s 75 species of true mangrove to be found in Indonesia. (5) Therefore Indonesia is the country possessing the most mangroves both in area size and in the number of species. This wide variety provides a rich environment and canopy for numerous wildlife of which crabs are keystone species: the presence of this animal makes it possible for many others to survive here. 2 3

Accommodation space refers to the space between the level of the substrate and the highest level that sediment could remain without being eroded away. (Jervey 1988) Also known as Oriental region, a zoogeo-graphic area occupying the southern part of Asia and most of the islands between Asia and Australia of which Borneo also is a part of.

They go through their larval stages in the water near the roots of the trees. When they are mature they climb up and feed on the leaves. This way they are crucial for the leaf litter production that make the mangroves such a rich ecosystem. (8) Mangrove forests are one of the most carbon-rich forests. The mangroves convert carbon dioxide (CO2, a greenhouse gas) to organic carbon (C) through photosynthesis and then store it into its biomass. There is an estimated capacity amount of 100-200 ton C per hectare which is why they call mangroves the carbon sink of the world. In the ideal scenario where mangrove forest would be increased on a large scale, even more carbon dioxide could be converted. Today however, mangroves are more logged than anything which even releases CO2 and increase the concentration in the atmosphere. (5) It is clear that the mangrove forests play a key role in climate change, coastal protection and carries a significant economic potential for Indonesia (around Rp 820 trillion).This last one has led to the current over-exploitation of land. (5) What seems to be overlooked by ignorance and greed are the once healthy ecosystems that could protect the introduced aquacultures and industries from natural hazards.

3_For greed all nature is too little The key-drivers of mangrove loss

Before the 1970â&#x20AC;&#x2122;s mangroves were considered wastelands, useless, mosquito-infested swamps. This preconception made it easier to exploit the mangrove forests as cheap and meaningless land that could be used for all sorts of useful and economic purposes:

Shrimp farming

Mangroves have been widely cut all over Indonesia for extensive shrimp farming, supported by millions of dollars of World Bank loans and succession rights provided by the government. This led to fast and unconstrained distribution of shrimp aquaculture in the country. In total shrimp pond expansion has lead to 50% loss of the mangrove forest in Indonesia. (5) The highest peak was due to the â&#x20AC;&#x2DC;Shrimp Feverâ&#x20AC;&#x2122; of the 1980s. Where the development of the world shrimp market was introduced and massive amounts of mangroves were cut in the whole of Southeast Asia. (9) When shrimp diseases hit the pond production, many investors went bankrupt while others moved to other coastal areas. It is reported that 250 000 hectare of shrimp farms are left abandoned. (3) Current aqua-cultural operations in Asia show a better prospect on the future by having mixed cultivation methods. For example in Vietnam, where shrimp farming is being combined with mangrove rehabilitation. In the Philippines mangrove is integrated in the pond system for fish and crabs. Also Indonesia developped a variation on their traditional system (tambak (pond) system): tambak empang parit, also called mixed-farming crop ponds system. Although, heading in the right direction, these systems need to evolve more and more research is needed.

Agriculture

In South Kalimantan and thus Banjarmasin, the mangroves were almost completely cut down and replaced for rice paddies and horticulture. (5)

Lax spatial planning

The pressure on the land gives governments the urge to make hasty decisions and to make short-cuts by sacrificing mangrove systems. These human exploitations made the mangrove forests thinner. Today the areas are more vulnerable to heavy storms and tsunamis than with the dense, mature forests of the past. But the thinned out forest doesnâ&#x20AC;&#x2122;t only affect the threat to the physical environment but also on human health. A study conducted by Flores NTT from 1970 to1990 concluded that malaria outbreak was closely related to mangrove loss. Also the shrimp ponds that replaced the mangroves are now left abandoned and polluted which affect the communityâ&#x20AC;&#x2122;s sources of drinking water. (5)

Existing regulations

Management of mangrove ecosystems in Indonesia is under supervision of five ministries: the Ministry of Marine and Fishery, the Ministry of Home Affairs, the Ministry of Life Environment, the National Land Bureau and the Ministry of Forestry. They all have their own focus concerning mangrove management. For example the Ministry of Marine and Fishery is dealing with the mangrove resources and the importance of these to mangroves in coastal fisheryâ&#x20AC;&#x2122;s. The Ministry of Forestry however, has the leading authority in managing mangroves in the country. Mangrove resource management in Indonesia consists of mangrove forest exploitation, protection and rehabilitation. Due to the many authorities overseeing the mangrove regulations, there is no one clear policy. This leads to confusion and carelessness towards the regulations. Mangrove forest exploitation is managed by 2 main regulations. The first handles about the silvicultural practices in mangrove harvesting and the second controls the leasing arrangements to allot the mangrove forest concessions. (2) 2

Accommodation space refers to the space between the level of the substrate and the highest level that sediment could remain without being eroded away. (Jervey 1988)

Silviculture

In 1933 mangrove harvesting was regulated for the first time. It was allowed to cut mangrove within 3 km from a settlement, to control mosquito plagues. By 1938 a clear cutting system was introduced where seed trees (mother trees) of 20 cm diameter were to be left uncut to procure the regeneration of the cut areas. World War II interrupted the application of this regulation, thus uncontrolled cutting went on for years until 1978 when the rule was finally put into the official law. In addition to this law they introduced a Decree that stated the silvicultural system: Seed-Tree-Method where cutting is only allowed in areas where 40 trees with a minimum diameter of 20 cm and spaced 17 m from each other per hectare can be left to produce seed for regeneration of the forest. This Decree includes a green belt of mangrove to stay untouched: 50 m along the coast line and 10 m along the rivers and main roads. In 1990 a Presidential Decree was composed that stated that the width of the mangrove green belt in any coastal area should be set up to 130 x the annual average of the difference between the highest and lowest tides. (2)

Concessions4

Before 1970, the provincial government had the power to issue all permits, disregarding the size of the mangrove area to be leased. In 1970 the Indonesian government modified the leasing process. From then on the Minister of Agriculture was entitled to issue concessions of mangrove forests of more than 100 hectare for 30 years. From 1983 to 2002 the Ministry of Forestry added a permission for provincial governments to grant 2-year concessions for mangrove forests smaller than 100 hectare to attract foreign investments. From 2003 on, only the central government was entitled to arrange leases. In 2009, just three concession holder companies were still operative in Indonesia.(2)

Even though regulations on mangrove management has been introduced since more than half a century ago, Indonesia still has lost 5 million hectare of mangrove forest (mostly in the 1980’s and 1990’s) as a result of uncontrolled development, a scattered and weak law enforcement and an absence of supervision from the government. Looking back, the ‘regulated’ forest exploitation has not been a good evolution for Indonesia. There were many cases where trees cut by the companies were more than allowed and trees where the diameter was smaller than the allowed minimum. It is also reported that some government field officers were involved in a ‘collaboration’ with companies and high officials were bribed to close their eyes. (5) Next to the regulated, legal mangrove exploitation, there is also the illegal. This is defined by the central government as a national problem: it happens in all the Indonesian provinces, cost the nation a lot of money (2010, Rp. 14,13 trillion, source: Jakarta Post) and it is almost impossible to control. (5) Human greed and uncontrolled development have been taking over mangrove land for decades now. Today the ecosystem exist in an alarming minority. Therefore, there has never been a time like now to turn things around and carefully plan the future of the mangrove in Indonesia. This has to go together with a consensus between all stakeholders towards a one clear strategy.

Concession holders are given the right to exploit the forest within the regulations fixed by the Indonesian government.

4_Strategies for Banjarmasin 1 Community involvement

Local community involvement from the start is very important. The mangroves traditionally were sustainably managed by local settlements, they were really valued by the people. Involvement of NGOs and local governments is also needed to really insure sustainable development where the NGOs can support the local villages and the local governments can make appropriate guidelines and supervise the whole. (3) In Da Loc, Vietnam a project called CARE worked closely together with the community to restore mangroves. The project aimed for an improvement of awareness and empowerment of the local community by ensuring their security by restoring the protective green belt and at the same time generating new sources of livelihood. The inhabitants were trained in collective management on how to create nurseries, plant mangroves and take care of them. A core group of local enthusiasts was created to really support the project as leaders of subgroups: nursery group, planting group, protection group, ... As a result the mangrove greatly improved in quality and quantity and although still young the mangrove already changed the environment by stabilizing the soils and an increase of marine life. The 50 hectare of mangrove planted along the coast (700 meter wide strip from the sea to the village) will form a protective dike when mature. (10) Developing a platform for over all participation, eduction and by doing this really including the community; is crucual as a start and as a consistent factor in every step of the strategy for the future of the mangroves in and around the region of the city of Banjarmasin.

2 Conservation of existing forest

Before talking about reforestation it is important to conserve the mangroves that still exist and prevent further loss of mature, indigenous species. The remaining species can then get a chance to recolonize the territory. As mentioned, co-management between local communities, scientists, NGOs and local governments must be clearly fixed to conserve the existing mangrove. Along with this, land tenure rights must be granted to the communities to ensure real interest and enthusiasm that go together with a sense of ownership. (3) Along the Barito river near Banjarmasin we can see that almost all mangrove forest is gone. The ecosystem has been replaced by port area and settlements. When we have a look outside the city, more southwards there is hardly any difference. But in this case most of the mangrove has been replaced by agriculture, only a tiny strip along the river is left. (image 7) Entirely to the south (along the Java sea) we can see that there is still some mangrove left but also massively replaced by fisheries and shrimp ponds. The importance of the mangrove forests seems to have been forgotten by blind development. Development has not been guided, regulated well in the last decades which lead to this robbed landscape of its natural ecosystem. It is important to learn from the past and learn from cities in other countries that dealt with similar issues. Ca Mau (Vietnam), for example, a city that used to be surrounded by massive mangrove forests as well; went through wars, heavy industrialization, agricultural development, ... which lead to its dramatically reduction of mangrove forest. For this city UFO3 (Explorations of Urbanism) did a research design: Mangroving Ca Mau. In this design, mangroves were given a new ĂŠlan, a new role for the future. A framework was created where both nature (mangrove, future sea level rise) as man (rice production and shrimp farming) could coexist while the mangroves act as the mediator between land and water. (1)

2. Development driven scenario

3. Balanced scenario

> Strategy map: Interplay of mangrove and port.

3 Preparing room for the future

For Banjarmasin the Ca Mau project can mean a source of inspiration. Reconfiguring the role of the mangrove in the current context will be of great importance in Banjarmasin as well. The clearing of the mangroves in the past can be seen as a blank canvas to start from today.

City vision

Between 2011 and 2012 Banjarmasin was chosen as on of the pilot projects for the ‘City Development Strategies’5 (CDS) approach. With this a ‘City Visioning Profile’ was drawn for Banjarmasin and named: “Gateway to Kalimantan”. Three main visions for the city were projected: Banjarmasin as economic hub, as traditional river city and as livable city. It is clear that Banjarmasin will play a dominant role in the development of Kalimantan. For this gateway a sea port and regional railway line will be introduced in the area. But first on the agenda is the area south from Banjarmasin, which is the regency of Banjar, where they plan an additional harbour to Trisakti where the regional Kalimantan railway line will plug in to in time.

Mangrove framework

The mangrove here, will serve as a framework for the landscape in transition. In the first place the Barito riverbank and the existing waterways landward will be tackled. (image 10) In time the mangrove forest will grow mature and form a protective dike for the region in and around Banjarmasin. This way the mangrove’s leading role in the landscape is re-established: acting as the mediator between water and land where future expansions has to take the mangrove forest into account and not the other way around. The mangrove forest will grow and decline according to the time frame of the development: f.e. The railway line is not yet built but while pending, the line for the railway line is shaped by a linear orchard or coconut trees. The point is that whether the plans will go through or not, the main framework of mangrove is set out. Thus if the railway would not come through, this is not a problem: the established trees can stay. If the railway would be built, this is OK as well, because the right place for it was planned in the framework and no mangrove forest has to be cut down to do so. Therefore, the framework of mangrove is strong enough to adapt to either an ecological driven scenario, development driven, a balanced one (image 10) or anything in between. Adapting to the territory in transformation leaving and creating suitable room for the future plans of the city.

To develop an economic hub with all its massive infrastructures (port and railway) and at the same time maintain a traditional and livable city, it is important to plan with caution not to encroach upon the land as before with an unsustainable, scattered landscape as a result.

4 Restoration of mangrove

In this stage community participation has started and measures are being made to conserve existing mangrove forest. Now room can be prepared for future developments through strategic afforestation and restoration of the forest.

Distribute knowledge

“Restoration follows where conservation has failed, or where disaster has struck. Of course, failed con-servation can be looked at as a disaster itself.” said Quarto in his report of mangrove reforestation. (3) Restoration in the past has not always been successful. The intension is there but the right strategy to do so is absent in many cases. Either the mangroves are planted in the wrong places interfering with other important ecosystems such as the swamp or the mangroves are planted using only one or two commercial mangrove species.

Pilot project implemented by UN-Habitat and the Directorate General of Human Settlements (DGHS) of the Ministry of Public Works as a tool that help local governments to develop comprehensive strategies for urban development in order to link public funding with local investors.

This then leads to a lack of biodiversity, an unhealthy ecosystem and a inefficient restoration process. Millions of dollars are being pumped into the projects but because of monotonous management the actual goal is missed. (3) To create a sustainable mangrove forest it is again important to work together: scientists, NGOâ&#x20AC;&#x2122;s, locals and local governments putting their knowledge and resources together. These resources encompass the existing site conditions together with the desired and needed mangrove species to be restored for that specific location. A correct restoration approach can reduce the cost of restoration enormously. Introducing an educational program to distribute this knowledge and involve community members is important to insure a sustainable restoration and empower local communities. (3)

Ecological Restoration Approach

According to R. Lewis6, there are three approaches which are used in mangrove restoration programs: 1: Hydrologic restoration with no planting 2: Hydrologic restoration with planting 3: Planting without consideration for hydrology The first method is natural and proofed to be the most successful and ecological because it leaves the seed trees or mother trees as they are and this way a natural colonization can take place. But this method is also the most time consuming. The second method is artificial but also effective and provides a quick recovery by planting young indigenous mangrove that were cultivated in the nursery. But the cost of planting may double the overall cost of the project and may limit biodiversity. Method 3 is applied most commonly and always leads to problems. Mangroves species are very fixed on their specific hydrological requirements, not all species grow according to 6

the same conditions. Planting species where they should not be is often more damaging than helpful. Most mangrove restoration of the 3rd method utilize one variety of mangrove: the Rhizophora or Red Mangrove. This mangrove is fast growing, tall and grows straight, perfect for building construction. But this leads to a monotonous, unhealthy mangrove forest. (3) The mix of mangrove species is vital in creating a robust and more natural self-regenerating mangrove forest for the future.

5_Mangroves as a framework for future urbanity Mangroves carry a undeniably high potential to deal with future growth in Banjarmasin through a coexistence of ecosystem and development. The territory goes back to its roots and the mangroves obtain a renewed responsibility. It establishes its position within current communities, the city, the country and the world. Working with the mangrove as a framework, for urban growth in the territory around Banjarmasin is a win-win-win situation. Local communities are protected, empowered, receive new sources of livelihood and can preserve and pass on their traditions related to the mangrove. The city of Banjarmasin is able to grow in a sustainable way guided by the framework of mangrove and supported by local settlements. Indonesia can invest in mangrove restoration that is truly worth the effort and the money through ecological restoration approaches enhancing the quality and the quantity of the mangrove ecosystem. Finally on the world scale, mangrove restoration in Indonesia and the other carbon sinks of the world, can help with the battle against green house gasses and reduce the effects of global warming. > Image 11+12: Port as clearance in the mangrove forest, structured by waterways and vegetation.

Territories of Absorption The Successional Transformation of Expanding Regions in Banjarbakula, Indonesia

Banjarbakula Metropolitan Region Banjarbakula is a territory structured by a deltaic water system joining the Java Sea. Metropolitan Banjarbakula is composed of five regencies of Banjarmasin, Banjarbaru, Banjar, Tanah Laut and Barito Kuala6, 11. Its total population of over 1.3 million is expected to double to over 2.5 million by 2030. Its creation drew from the spread of uncontrolled sprawl development and the aim to assimilate further growth with the strong polarity of the greater Banjarmasin area, composed of the three cities Banjarmasin, Martapura and Banjarbaru5 (Noor, 2015). Banjarmasin, the oldest city, developed from a centre on the Martapura River and consolidation of linear river based settlements. After the end of Dutch colonization, Banjarmasin grew exponentially12 along the Martapura and Barito Rivers on lowlands under the sea level. The landscape changed dramatically with the introduction of rice, shifting from swamp to productive landscape. Water was and still is the basis of food production and livelihoods (Water Urbanism Studio, 2015). Martapura developed from the profitable gemstone mining activities to the south while Banjarbaru is a planned city, designated as the new provincial administration centre of South Kalimantan. The National Medium-term Plan of Indonesia places importance on Banjarmasin, Banjarbaru and South Kalimantan as a whole in their role as primary service centres2, 8 attracting new growth[RPJMN, 2010]. Historically, what is now Banjarbakula area was composed of swamp lowlands stretching into the forested hills3, 4. In recent decades, the remaining ecological landscape of swamp, mangrove forests along the Barito River and the tropical forests in the hills became a source of big business for companies with private concessions for extractive resources. These concessions promoted oil palm and rubber plantations, shrimp farming, logging, gemstone mining, quarrying and excavation at the expense of ecology, water systems and water quality [Halim et al, 2013]. With the development of road infrastructure urbanization has shifted from water-based to a roadbased orientation.

Necessity for Absorbing New Growth As the economies have evolved so has the territory, with transposed systems that continue to alter its realities. These changes continue to revise the undercurrents of the urbanizing poles, Banjarmasin, Banjarbaru and Martapura, which are currently expanding. These dynamics demonstrate the rampant urbanization pitted against natural resources. It is essential to examine the character and potential of these poles to receive projected growth.

Banjarmasin Banjarmasin, originally a water-based merchant city along the Martapura River, has grown to become a port city.The population of Banjarmasin rose from 66,000 in 1930, to 444,000 people in 1990, to 652,000 people twenty years later in 2010 and has been projected to double to 1.27million people in fifteen years in 203010. The city’s edge on the Barito is dominated by the Trisakti Harbour and related industrial/economic activities that partly depend on harvesting the territory of its forests and plantations.

The city is downstream of the Martapura River, obstructing the water’s natural floodplain. It is located below sea level where the effects of tidal fluctuation, saline intrusion and rising river levels in the wet season are experienced dramatically (Water Urbanism Studio, 2015). The Martapura River’s network of tributaries, which are increasingly getting canalized, are subject to excessive sedimentation from deforested zones and water pollution from settlements.

POPULATION DENSITY

Banjarmasin’s fringe is a dynamic section growing into the paddy fields and forming linear growths along regional infrastructure. Swamps are filled with material from excavated hills transferring the land condition to the sprawling edges of the city and along the infrastructure corridors emanating from it13. Banjarmasin is envisioned as the ‘Gateway to Kalimantan’ building on its tenets as a traditional river city, as a regional economic hub and a liveable city [UNHABITAT, 2012]. This vision directs regional growth to Banjarmasin with the expectation of capacity to absorb and expand for growing populations. Expansion means the paradoxical reduction of the food production landscape when there is a projected need for higher production. Therefore, the exponential growth will have to look to the surrounding territory as Banjarmasin, with a density projected at 17,755 people per km2 in 202811, will inevitably spill outward unable to cope with this upsurge. 15

of an orthogonal garden city. Its designation as the headquarters for provincial administration elevate it from a local city to regional city, expected to absorb the regional paraphernalia that accompanies the task such as new infrastructure, bigger economies and new settlement [Water Urbanism Studio, 2015]. It is a porous, distributed city14, with a density of 409 people per km2 in 2006 and a projected density of 1,203 people per km2 in 202810. Banjarbaru is capable of receiving measured spillover growth from Banjarmasin and Martapura at this juncture. Banjarbaru is already housing populations that work in Banjarmasin, part of the production cycle of goods/ foods destined for Banjarmasin and large scale infrastructure such as the Syamsudin Noor Airport. Banjarbaru’s capacity to absorb make it an integral part of the economy of Banjarmasin. Simultaneously, the city limits are fast inching outwards and densification will occur within these limits.

Banjarbaru and Martapura Martapura and Banjarbaru have in recent decades coalesced to one urban zone bearing different identities12. Martapura started on the banks of the Martapura River and continued to grow on the adjacent land higher than swamps. It is the meeting point of the tidal wave effect and the pressure from the two tributaries, Riam Kanan and Riam Kiwa, flowing down the hills. As such Martapura’s edge on the river experiences flooding events in the rainy season and low level inundation in dryer months. Martapura city is bound by the river northwards and swamps on either side. Thus the only edge capable of sound expansion has grown southwards into Banjarbaru merging the two cities15. The expansion possible in Martapura is inward through infill and densification which is not sufficient for doubled growth. Banjarbaru is the city on the highest topography. It was planned based on the Ahmad Yani Road with the principles Fig 16: Adapted from Fig 7 Fig 17: UNHABITAT, 2012

The future plans for Metropolitan Banjarbakula7 feature a consideration for where the new and the extensions will go. They propose commercial zones, a new port with related industries, public spaces and even conservation areas. However, the plans do not reflect how the new work with the old only superimposing on an existing system. How does the existing system react to this imposition and vice versa? The possible interactions that could arise will impact expansion of settlement on ecological or productive areas and dysfunctional growth. The redeeming aspect of this plan is that it designates green protected areas which are presently under threat of exploitation. A resolution of the relationship of these proposed elements to each other, to the context and to future growth necessitates further strategy. The capacity for expansion creates the possibility to reshuffle certain activities. The difficulty is that every part of the territory has its purpose linked to economy or urbanization. It is unfeasible for the two urban zones to absorb the expected doubling of the population of the region. Banjarmasin’s city vision takes into account goals for growth in the future. This has led to city extension proposals to Alalak and Gambut17 [Noor, 2015, UNHABITAT, 2012]. These plans mean land conversions from rice paddy to city and from swamp to city. There is need to find suitable locations in the territory that can take new populations, economies and the infrastructure to support them. Currently, the projected areas of growth extend on swamps and rice paddy zones effectively reducing their ecological function and yield capacity respectively16,17. There is need to find absorptive areas in the Banjarbakula Metropolitan Region that are already ‘connected’ to the current tissue, social systems, infrastructure and economic logics. Areas that provide room for future landscapes while safeguarding the essential existing urban, productive and ecological landscapes. Finding these areas can allow the re-prioritization of the landscapes, depending on new necessities or pressures arising from growth. 17

Fig 18: VERTICAL LANDSCAPES, investigation of the territory

Investigating the Growing Territory The search for absorptive areas requires an investigation of the territory. This landscape-based approach of design investigation is to first identify the character of the territory, how this character has shaped growth, absorption and if visible adaptation to evolving uses.

Landscapes in Conflict Banjarbakula is made up of five vertical landscapes18 based on the type of soils. These are mangroves, paddy fields, swamp, mines, plantations and tropical forest. They are places in transition experiencing scalable landscape conflicts that are representative of the problems facing South Kalimantan.The expansion of settlements with increasing populations has prompted the encroachment of ecologies of mangroves, forests and swamps19. There has been a devastating loss of mangroves in the conversion of land to rice paddies. Swamp areas have been fragmented, filled and drained 18

reducing the water storage capacity of the floodplain thus a higher risk of extreme flooding.The forests have been victims of concession and illegal logging activities impacting in large-scale deforestation with increase in river sedimentation. Another large scale land conversion has been the adoption of rubber and oil palm plantations which have required and felled vast amounts of forested land resulting in devastating deforestation and soil erosion20. Oil palm produces higher revenues for the region and has become the preferred cash crop. The danger is that the oil palm plantations surveys have identified over 60% of the Banjarbakula land as potential zones for oil palm plantations. While forests have given way to oil palm plantations, the food production zones could be next. At the same time small scale economies are affected by preference for oil palm which is established by big companies while rubber is operated by small scale holders. This premise questions the focus on economic development at a regional level but

overlooking the small scale. New developments, both settlements and industrial, along infrastructure corridors are cropping up on filled swamp land and are increasing rapidly21. Settlements along canal systems comprising productive housing are also expanding. This increase in development arises from water and infrastructural configurations within rice paddy fields. Paddy fields are starting to become the absorptive landscape for infrastructure and industry. The consequence as mentioned previously, will be a fragmented productive landscape of reduced capacity and yields. The industrial growth appears dispersed but road based stretching across different landscapes. New industries have been proposed in swamp areas which will further lead to land conversion. The gemstone mining, quarrying and excavation activities have created scars in the landscape by altering the topography22. Excavation mines have migrated entire sections of the hills to the swamp fringes of Banjarmasin flattening large chunks of land along with the tropical forests that stood on them. Gemstone mines have dug into swamps and forests along water drainage paths to leave contaminated pits that have eventually filled with water. The quarry is in the heart of the forest next to Riam Kanan, one of the tributaries of the Martapura River causing deforestation and sedimentation. This inversion of topography is driving land conversion, giving the swamp the ability to absorb development. The flattened lands are also converting to residential developments. D’Auria and Vescina [2008] on La Plata, Argentina, write about such results caused by the indefiniteness of a landscape. It allows all manner of appropriation of resources as they are open to interpretation which varies for individuals. The ecologies of Banjarbakula face such indefiniteness. Economically motivated appropriations which are largely uncoordinated generate conflicts of use resulting in degradation of resources with domino effects on water storage capacity, sedimentation and water quality issues. Despite these conflicts it is possible to envision possible productive appropriations that may not imitate the original but protect its existence. It is inevitable that these activities will continue as most are sanctioned by the government implemented by private companies while others are by individuals or small groups in response to economic tensions. Andrusz provides another characterization of this discord of economy versus ecology. He outlines that regions in metropolitan zones such as Banjarbakula can be divided into two types, ‘ruined and peak zones’. Ruined zones have been degraded by capitalist activities while the peak zones have been ignored by the same capitalist motivations [Isikkayaa, 2012 citing Andrusz 1996]. The succession of these socio-spatial dichotomies have resulted in extensive land conversion, from a natural state, to a modified state, and to a replacement state. If these trends were to continue in a similar manner in the context of exponential growth a catastrophic future is to be expected

characterized by intense flooding, contaminated water, destroyed water catchment zones and lack of food security. The effects of climate change requiring adaptation also emphasize this competition of values between rapid growth and degradation of resources. Flooding, tributaries drying up from disturbed sources, reduced rainfall and projected sea level rise are problems that future growing populations in Indonesia will contend with [IPCC, 2014].

Effect on the economy Water-based economies generate more than half of Banjarmasin’s economy through related transportation, finance, and services activities [UNHABITAT, 2012]. However, monetary conversion and consequent degradation of resources has had negative economic returns. Banjarmasin’s primary extractive industries are facing decline, particularly rubber and timber extraction. While they are products that depend on cyclic growth patterns, they have been harvested uncontrolled without any regard for regeneration time. The decline of both industries has resulted in exhausted, degraded and converted landscapes and reduction in job availability. To remedy these problems, part of the plan by the city is to grow its service and tourism sectors. These plans, in addition to the low growth rate of manufacturing industries heralds a new kind of economic growth that requires the relevant infrastructure and programs to achieve. They require modification of existing land uses to absorb new capacity. Banjarmasin intends to strengthen the city’s role as a port city by upgrading and extending the port in the future thus encouraging new industrial and related economic activities along the banks of Barito River [UNHABITAT, 2012]. It is clear that Banjarbakula’s landscape is changing at a fast pace and will continue to change due to resource economies and adaptation to the outcomes of this dynamic.

Capacity-driven conflict mitigation in absorptive territory Banjarbakula requires a landscape conflict mitigation process with capacity-driven focus. The approach proposed in this case is to use the points of conflict as an entry point to both needs of conflict mitigation and finding room to grow. Finding room for the new in the landscape can mean re-evaluating certain sites. Wall proposes ‘peripheral sites’ that are at the moment deemed to lack influence. These sites can hold potential to become important locations to receive new growth [Wall, 1999]. Through design investigations an in-between zone is identified between the vertical landscapes, a zone in transition into a new use23..These ‘peripheral sites’ have the characteristics of their flanking landscapes expressing ecological value and urbanizing tissue in various degrees. Desvigne, in his interviews with Bordeaux, proposes such a system that focuses on such traces that are almost invisible23, transforming them into new landscapes so effectively that “everything remains in 21

place but its nature changes”. These zones can form points where the new can be accommodated while simultaneously correcting the deficiencies and conflicts of the existing landscapes that flank them on either side. This absorptive capacity for new growth can be channelled to upgrade the existing landscapes based on ecological systems which accordingly can remain in their place. Desvigne does point out that this system is not intended to be a restoration but a transformation of the landscape [Bordeaux, 2009]. These landscape transition zones form the starting point for absorbing future growth24. Transition zone 1 is between conflict of the natural forces of the Barito River, degraded mangroves and rice production paddies. This transition zone is crucial to create a protection system for the river banks by reforestation of mangrove forests. This zone is also capable of absorbing the planned harbour with related industries and new settlements such as desakota*. Transition zone 2 is between the conflict of the city of Banjarbaru and the swamp. It has the capacity to absorb new urban ecology protecting the swamp edge, new public space for the city, desakota and productive swamp to benefit economically from ecology without land filling. Transition zone 3 is between the conflict of mines, swamp, plantations and Banjarbaru city. It has a promising possibility of transforming into a new mixed city, new ecology, and new economies/industries due to its strategic position on high topography, adjacency to the new provincial administration, strong infrastructural connection and its industrial farms. The mines provide a possible structure of open spaces for new growth. Transition zone 4 forms the conflict of forest and plantations where there is deforestation. It is capable of absorbing reforested community forests ran under social forestry programs and controlled sustainable logging. These zones are capable of receiving the new to correct the problems of the territory by responding to growth pressures with the landscape as priority. Eventually they expand into the rest of the vertical landscape, adapting and growing into it as the sustainable future expansion necessitates into a transformed landscape. Desvigne warns that predicting the specific type of city that will be built decades from now is impossible. Therefore, an ‘intermediate nature’ must be planned for requiring and designing for flexibility. He states that “the idea of transformation overtime thus leads one to imagine urban forms that are not superposed on the site but that draw their substance from these changes”. Such a process means that only certain future programs are proposed adapting to future changes. In this way coherence may not be immediate as the territory is in ‘perpetual transformation’ with a deferred completion [Bordeaux, 2009]. Perpetual transformation necessitates consideration of the growth at every stage of transformation affecting the capacity of absorption of new programs at a later stage. Wall’s [1999] writings supports this with the statement that “the goal of designing the urban surface is to increase its capacity to support and diversify activities in *desakota: Settlements having both village and city characteristics

time-even activities that cannot be determined in advance, then a primary design strategy is to extend its continuity while diversifying its range of services”. Capacity-driven planning and design works towards resilience of the region by incorporating the new elements either missing or inadequate. At the same time the consideration of the quality of landscapes generated at various carrying capacities entails the choreography of new conditions for a tentative time. Wall also suggests that focus should shift from forms of urban space to processes of urbanization in capacity-driven design utilizing the regional scale networks. Visualization of these processes considers larger dynamics which may include; shifts in economies, how industry types will evolve, how settlements might consolidate or shrink, how entire plantation blocks are being replaced, how infrastructure will morph or how water appropriation systems might change. In totality how these processes influence the imprint of growth on the territory in time. He combines capacity-driven design processes with their transformation over time, as a system of successional transformation.

Successional Transformation of Absorptive Territories Following these perspectives, the design strategy focuses didactically on the successional transformation of absorptive landscapes. The strategy is the process and the process is the strategy. It takes advantage of the immense potential of the transition zones by planning for processes that will change over a period of time. Such an approach evokes a sense of uncertainty. Prominski [2005], however, highlights the unpredictability of evolutionary processes where he argues that “uncertainty is not seen as something that has to be resolved, but as an integral part of the design”. He is quick to point out that success of this system is only possible with ‘specific instructions’. In his case these specific instructions consisted of a water management framework with a formal system that encourages evolution which manages to be coherent in the future. He proposes the term ‘limited self-organization’ implying a sense of freedom in change over time but its purpose directed from the inception. This starts to question the kind of ‘specific instructions’ that can be enforced to encourage successional transformation of the landscape. These instructions can start with the categorization of these absorptive landscapes. As ecological in character, comprising forests, swamps, mangroves and river edges; or as emergent rural-urban zones that are starting to urbanize. In both instances the programs and character of absorption must be different as it is entirely based on the composition and deficiency of the zone. The project strategy focuses on Transition zone 124 (Barito River and mangroves) as an ecological absorptive landscape and zone 3 (Mines and emerging industry) as emergent urbanizing absorptive landscape for their strategic position in the regional networks and potential to absorb future growth. 23

Instructions and Catalysts Corner speaks of allowing flexible change and adaptation of growth over time in such landscapes that are considered in terms of scale. He proposes designing the process using ‘catalysts of transformation’ as opposed to designing a static proposition [Bordeaux, 2009]. Field Operations’ [2006] proposal for the remediation and development of Fresh Kills Park, New York adopts such a successive process.Where each stage is driven by catalysts from the previous stage25. In the case of Banjarbakula, three stages have been considered where specific instructions and catalysts of transformation have been applied26. The first stage, before growth spreads into these absorption territories is to set up a protection system by re-establishing ecology and building a landscape structure where ecology is a frame within which growth will take place. The second stage is to steer growth in favourable direction by reinforcing the appropriate and catalyst infrastructure reinforced with social centres. The third stage, and the stages after, are adaptive stages where initial absorption has taken root and there is increasing pressure for food, water, more space to grow. Expansion can be envisaged further into the landscape in a sustainable and cyclic method. Middle phases develop and sustain relationships between re-establishment of natural resources and intense use later. Ecological Absorptive area strategies face the challenge of how to prioritize ecological value while supporting economies of scale such as extensive paddy fields and plantations. They face growth pressure from settlement, food production and industry. Therefore, every addition to the system has a role in safeguarding ecologies and natural protection systems while increasing capacity. The water structure of creeks and rivers defines the location of the new programs26. The strategy envisions the harbor and new industries from a mangrove point of view which forms a protective mass at the banks. The new port is absorbed in the mangrove forest, structured by waterways and vegetation. A hybrid protection system from erosion and saline intrusion is created, artificially by the built port edge and naturally by the mangrove forest. The paddy landscape that extended to the banks of the Barito River is pushed back, first entirely then framed by productive mangrove dykes with aquaculture. Urbanizing absorptive territories derive their character and potential for growth from the dynamics of existing land uses and programs. They require a system of absorption that build on these existing dynamics. Transition zone 3 is defined by intersecting regional roads that stimulate growth of industrial farms, mining and plantation warehouses. Its higher topography create its limits terminating at a swamp on the west and south east and extensive plantation blocks. Connectivity, topography and good soil conditions make it the best location in Banjarbakula to grow on. Its northern edge meets the sprawl of Banjarbaru and the new provincial headquarters. These dynamics of sprawl, growing plantations, evolving economies, growing industrial farms, inactive gemstone mines, and hyper active land excavation sites have spurred related transitioning satellite villages along the roads. The goal is to mediate the growth of settlement and industry steering it towards a mixed use transition by reinforcing

the ecological structure as a frame. Commercial, light industries and service components can be absorbed evolving with time to with settlements.

Open-Ended Absorption and Adaptation Wall [1999] proposes that the modern metropolis functions more like ‘a spreading rhizome’, proliferating the new and facilitative of change. This capacity driven system needs to be open-ended and adaptive. Banjarbakula can embrace the inevitable development but steer it appropriately to ensure the territory can absorb exponential growth and economies while natural systems are protected. However, clear directions have to be put in place to accommodate the tentative growth pressures subject to socio-political influences. According to Catoor and Gosseye [2008], consideration of the weight of economic and political regimes at a multi-scalar level dictates a level of flexibility as these settings can upset the precarious balance of urbanization with the natural systems. These are cyclical systems, each stage taking advantage of the substance of the previous stage thus increasing the resilience of the region. This espouses the idea of intermediate natures as put forward by Desvigne [Bordeaux, 2009] that utilizes successive phases that build on each other’s dynamics, at times coexisting, condensing, converging, progressing or employing historical rhythms. The benefit of this system is that it views development as a positive addition, albeit cautiously. Reflection of the regional scale of transformation considers that industries can diversify and evolve to new forms such as service-based, processing or research; plantation coverage or types can change effectively altering economies; informal economies become legitimate as part of an ordering principle; typologies can evolve to higher or mixed densities; provincial administration can organize new development; and that polycentric rural villages can consolidate into strong satellite towns. This uncertainty of planning and adapting systems of land use for future growth dictates the identification of how and where to expand the region; It considers what this system needs to be viable such as dyke, infrastructure and water, essentially the lines that matter presently and in the future; and establishes the guidelines that will ensure freedom of evolution.

A preface to the flow of mobility Contextual Study and Analysis The scope of design inspired us to see Banjarmasin and Banjarbaru as integrated entity in term of capacity and facilities but at the same time having their own identities and function to serve. Historical city Banjarmasin and itâ&#x20AC;&#x2122;s burgeoning new administrative capital Banjarbaru have to be connected in a way with a public mobility option which could prove to be more efficient and affordable for the inhabitants than their current mode of transports and help to improve and preserve the urban identity and form of the cities. In a quest of answers to how to design a correspondent public transport for Banjarmasin and Banjarbaru, it is crucial to understand some issues: what is the core mobility principle that is in function, how can this principle be advantagous or disadvantagous to a future possible public transport design strategy and whether or not existing infrastructure can be used to envision these strategies and how.

Existing hierarchy of major road infrastructure by Author

Comprehending the scales We firstly tried to capture Banjarmasin and Banjarbaru within the regional frame of referrence to understand the mobility flows. We We take into account two major types of existing infrastructures: arteries and collectors; It is apparent that the arteries carry both good carrying heavy vehicle (the regional flow) and a major flow of pessenger flow who need to move back and forth the major destinations of markets, universities, administration centres, offices, residentail areas in banjarmasin and Banjarbaru, while the collectors carry a light flow and they did not yet evolve to be bigger infrastructures but it is apparent that with the new planned agglomeration in the next few years those infrastructures will also evolve in a same way. The overall tendency, hence, is not resource efficient and overlook the future outcomes. In the existing situation, the Ahmed Yani road carries a heavy flow and often faces congestion, heavy vehicles can pass through the dense city to serve the riverside industries and the ring roads are planned to make thrice their current size. These tendencies are the reason why we can see â&#x20AC;&#x153;everyone moving on every roadâ&#x20AC;?, rather than an organized flow which serve different flows their purposes better.

A draft sketch of how the hierarchy can be changed to re-streucture flows by Author

The major flow lines have a potential to express themselves in two different scales, regional and urban. This is the first instance where urban public transport can be prioritized on the urban infrastructure, and thus making its flow uninterrupted and attractive for users. 5

A preface to the flow of mobility Contectual Study and Analysis Defining the latent interplay of flow The hypothesis of re-structuring the flows are instantly revised with a set of intuitive flow map. With the flow maps showing mobility of produced good on road and mobility of people on road, we further agree on the point these flows can be suggested to work as seperate layers, rather than being over-used and consequently bring in more new infrastructure in the network. This would support protecting the urban identity of the Ahmed Yani road and defining the productive green and protecting it from unplanned urbanization by placing the planned regional spine on the line that is passing across the proposed urban line. Car cities or river cities? It is obvious that, as a present and future potential important port city the importance of water in terms of trade and business is very significant here. This is also suggested by the flow maps. It is quite apparent that inhabitants are habituated to use water for necessary purposes; itâ&#x20AC;&#x2122;s the lack of suffiecient water infrastructure that puts all the pessenger transport flow on the roads.

Projects to learn from The design discourse came to a point where implementing a Bus based public transport was decided relevant. The main goal was to test a system which can be integrated with the existing urban environment, would be rather cost efficient and could easily use the existing infrastructure.

The BRT project in Ahmedabad, namely Janmarg, however, built in 2009, was proved to be quite successful. The design was a result of a comprehensive analysis of urban forms and settlements; and the project successfully avoid the mistakes done by prior BRT projects in India.

This chapter of the paper discusses about the research on relevant projects that seemed important to learn from. The Curitiba BRT project in Brazil is a famous project with its influence on sustainable city building process all over the world. It is an ideal case to learn from but an important question to answer was to that, how is this being followed in cities that are contextually relevant to Banjarmasin and Banjarbaru. Hence, the BRT projects in Jakarta, Indonesia and Ahmedabad, India are also investigated. TransJakarta started in 2004 as Asiaâ&#x20AC;&#x2122;s first BRT project. Even though, it created positive difference in public infrastructure usage in a city where motorized two wheelers and cars are largely popular; it faced major problems, such as bus congestion on dedicated lanes, accidents while using the Bus etc. and for most of it, the lacking of future vision in deisgn and the poor management can be held responsible.

Projects to learn from BRT of Curitiba, Brazil The Bus Rapid Transit (BRT) of Curitiba is globally famous for its sustainable design and implementation. This has played a big role in making Curitiba a livable city and one of the model cities in the world to introduce sustainable urban design principles. How the world leading urban design strategy came into place A population boom in Brazil followed the agricultural mechanization during the years 1950-1980, mainly due to migration of people from rural to urban areas. Regarding the increasing number of inhabitants Curitiba´s former Mayor Ivo Arzua initiated a public invitation to tender to face Curitiba´s growth and the linked issues in 1965. To find solutions for a third world city, limited in resources, large-scale and expensive projects were replaced by a number of simple and modest solutions. A group of young architects and planners, foremost Jaime Lerner, from the Federal University of Paraná replied and they laid out plans. Marked as a start of shift from top-down to bottom-up approach in city planning, this was quite a different approach of city during that time when sustainable urban development still was not in fashion. “Metro-nizing the Bus” The mass transit system of Curitiba started developing in the early 70s The main idea of developing the transportation system was to deploy buses which were used before, instead of building a new subway; due to the shortage of time and money. According to architect Lerner, compared with the Curitiba bus network, a light rail system would have required 20 times the cost and a subway would have cost 100 times as much. (Lubow, 2007) From this need was created a simple but sophisticated and integrated system of buses; the BRT of Curitiba, roads and a whole functional urban environment. A BRT is defined as a “bus-based mass transit system. A true BRT system generally has specialized design, services and infrastructure to improve system quality and remove the typical causes of delay.” Reorganization of the city’s road system introduced a unique road type, the Trinary roads (Sistema Trinário). These roads consists of two one way streets for local vehicles and pedestrian walkways on two sides and one devoted lane composed of two lanes for the express buses with

synchronized traffic lights providing smooth thoroughfare. (Gunderson, 2014). The express bus service was being developed to work in replacement of a subway- uninterrupted by traffic signals and congestion, fare collection before boarding, swift passenger loading and unloading and all these above the ground and visible. This idea is called by the principle designer, Jaime Lerner, the “metro-nizing of buses”. To increase the efficiency of the, tubular bus stops were introduced with same loading-unloading level, ticket purchase and boarding facilities separated before getting on the bus. The passenger don’t have to get on the buses with steps, instead by the ramp that extends out to these stops from the bus. The cylindrical, clear-walled tube stations with turnstiles, steps, and wheelchair lifts are attractive, comfortable and user-friendly; obviously they caters for specially-able users also. This tubular bus stops results in a typical halt time of around 15 to 19 seconds at a stop. (Goodman, Laube, & Schwenk, 2006) Creating an Urban Environment The success of the transport system does not only depend on the BRT system or the roads. There were other design decisions too which complemented this to make a functioning urban transport system. Following the principles of the new Master plan, the city center was partly closed to vehicular traffic, and a number of streets which had higher pedestrian traffic, were made accessible only to pedestrians. The designed treatment at intersection involved controlled and unhallowed turning of other vehicles and longer “green period” and shorter “red period” for buses at the traffic signals. Land use planning was integrated with transport design by encouraging commercial growth along the arteries radiating out from the city center and discouraging central area growth. And importantly, the land along the main arteries were for highdensity development while lands farther from these roads are zoned for low density development; this policy generates more transit ridership per square foot and pulls traffic away from the main roads. The five transit corridors work as physical references for the city development. This shaped the city to grow further not radially but along the designated corridors in a linear form. This is how the principle designer wanted to promote the idea of working and living together. 9

â&#x20AC;&#x153;While Indonesians currently refer to these systems as BRT, it is perhaps a question of semanticsâ&#x20AC;?- Sutomo, Heru and John P. Ernst.

Projects to learn from TranJakarta, Indonesia TransJakarta was launched 2004 by the city administration of Jakarta. This was the first full BRT system in Asia with separated bus lanes, same level boarding and pre-paid ticketing. Covering more than 172 km with its 11 routes, TransJakarta is now the longest and the most extensive BRT system in the world. BRT to save the city TransJakarta was a way for the city to improve the traffic condition of the city. Commuters used to suffer largely because of congestion and pollution caused by the increasing number of cars and motorcycles. This project initiated with the objective of building a positive image of public transport and use it as a catalyst for urban transport reform in other major cities of Indonesia. This would mean also to improve pedestrian facilities, non-motorized transport facilities, manage travel demands and reform land-use options. In 2011, the usability of public transport increased to a large number of 32% with the presence of BRT. This translated in a result of saving of more than 54,000 tonnes of CO2 emissions or equivalent of taking 10,000 cars off the road. A venture towards efficient transport Preliminary planning for the BRT System started in 2001, but it not until 2003 when the program was accelerated as a result of the mayor being inspired by the BRT system in Bogota, Equador. In February 2004, after only 9 months the first corridor of 12.9 km corridor was made operational and it cost around 2million USD. This would pass through the city center and along the two most congested road of the city. Following this, the rest of the 10 routes were built one by one is the next few years, the last one being built in 2013. The BRT stops connect residential areas, major Municipal infrastructures as stations and offices. Except the first corridor built in 2004, all routes have busses with CNG run on them, the more environmentally preferred option over diesel run buses. Articulated buses carrying 170 persons and single buses carrying 85 persons run on the busways. The elevated bus stop platforms connected to walkways, by pedestrian bridges and ramps ensure quick and easy access and efficient boarding for commuters and they can use the service for an affordable price of 40 US cents per

ticket. The BRT System is managed by BLU TransJakarta, a public authority under the transportation Agency of the Jakarta Municipal Government. Nine different bus companies operate the buses, and all operate under BLU TransJakarta. Some of these operators were formed from existing bus companies whose routes overlapped with TransJakarta bus companies, while the rest were selected from a competitive tender process. These operators are paid per bus kilometer travelled throughout their seven yearsâ&#x20AC;&#x2122; operating contract period. This makes it possible for the municipality to have the financial and revenue risks on itself. What could make Transjakarta Better? The reason the BRT System is considered as the metro on the road is largely because of the fast operational quality of the buses, this includes smooth boarding system and the physical designs of buses and station. The buses which run for TransJakarta could use better bus designs with doors on borth sides, separate doors for entering and exiting to meet the standard of efficiency compared to other BRT Systems worldwide. Also introducing bus lanes without regulatory measures increased congestion in the mixed traffic road in the case of TransJakarta. Being an unit under Jakarta Municipal Government, the management of BLU TransJakarta sometimes makes the operation process slow due to the proceduresâ&#x20AC;&#x2122; excessive bureaucracy. The TransJakarta was planned to be an example for the other citiesâ&#x20AC;&#x2122; BRT systems, however the most important issue to remember in this matter was to provide dedicated bus lanes for the buses and that was missing in the other BRT system, thus the realts were even less effective than those of Transjakarta.

“An increasing number of transport planners have started believing that a transport system that prioritizes walking, cycling, shared and public transport is equitable as well as low-carbon”- (Datey, Joshi and Mahadevia, 2012)

Projects to learn from Ahmedabad BRT Sysytem, India The Ahmedabad BRT, known as ‘Janmarg’, opened in 2009 is until today the largest BRT network in India. The global and national award winning project, since opening of the first corridor, carries .15-.18 million passengers per day. The mobility modes and transport tendencies on the roads According to 2011 census, at least 35% households in Ahmedabad had a motorized two-wheeler and 9.7% had a car. The number of cars per 1000 population was a still low: 117 in comparison to US (828), UK (544), Brazil (275) etc. However, with the vehicular growth with an inclining tendency and the high economic growth rate, the car growth rate will surely increase if not decrease. Although the walking and bicycling share is 42% on the roads, they are certainly not the preferred choices for the people. The public transport share is 16% but the Public transport systems in Indian cities nor have kept pace with the increase in demand, neither the service have been maintained or modernized properly, thus having people to turn to either personalized modes or IPT creating congestion and air pollution. The public transport share is 16% and although the fare is kept low but the Public transport systems in Indian cities nor have kept pace with the increase in demand, neither the service have been maintained or modernized properly, thus having people to turn to either personalized modes or IPT creating congestion and air pollution. In this context, a sustainable transport development strategy would be to keep the non-motorized mobility share constant, while developing the public transport, increasing its capacity, make it attractive for most people and make it more accessible.

city inhabitants. This was considered viable even when compared to the cost that would incur even a rail project was built instead; Delhi’s recently constructed metro rail of 190 kilometers (Phases I and II) cost $29.5 million per km while it would take the same amount of money to build a 2,900 km corridor of BRT. This would also be a motivation to keep the modal share of walking and bicycling constant as with the re-structuring of the road would also be a viable opportunity to include safe cycle ways and walkways. This would also be suitable over metro because of the urban forms of the city which has mixed land use and trips distributed in multiple directions that makes trip lengths low, thus a reason for low ridership corridors for efficient metro services. Development of Janmurg The project was approved in 2006 and work began in 2007. The proposed length of the corridor is 88.8 km which was divided into two phase; the first phase being 58.3km and second 30.5km. According to the preliminary expectations from detailed reports that were called by NUTP in 2006 and 2008, the roads would be well-laid with ample spaces for vendors, walkway, cycle ways and on-street parking space. The core idea of the project was to “complete a project, not a corridor”; so as to create a city-wide network, not just isolated corridors. The project learned from similar cases in Delhi and Pune, who built their BRT corridors in the busiest spines resulting complains from private car users, so with the idea of “connecting busy places but avoiding busy roads”, the first corridor was designed. The project did not cause problem of congestion because while constructing it provided a similar amount of road space as it occupied.

A paradigm shift in public transport The Janmarg project were conceived in 2006 when The Jawaharlal Nehru National Urban Renewal Mission (JNNURM) and the National Urban Transport Policy (NUTP) of 2006 took initiatives to bring a change in the scenario of public transport system and especially developing bus rapid transit (BRT) projects in particular in various cities of India. This initiative emphasized safe, comfortable, reliable, affordable and sustainable accessibility to jobs, education,and recreation for India’s growing number of 13

Design Strategies to Connect Public Mobility The public transit system is conceptualized as a component of the matrix of public places along the main road and river corridors. This is an attempt to reform the road from a transport corridor to a public realm and the river from a backyard to a place to celebrate. The strategy developed with the idea of integrating a BRT route with the existing and new planned pieces of infrastructure. Firstly, a “fast line” system is envisioned to run on the main spine connecting the two cities, the Ahmed Yani street. This flow is further supported by the peripheral roads of Banjarmasin city and the one connecting to Martapura road upto the market. In Banjarbaru this flow is supported by the parallel secondary roads to A. Yani. These “fast lines” are then made accessible with “slow lines” which would stop frequently and serve densely the new neiw future neighborhoods. The dense settlements of Banjarmasin would be also covered with the Water taxi connections, which would extend to the other side of the Barrito river and are connected with “fast bus line” by the “slow bus line”.

Design Strategies to Connect Public Mobility Public Transport as a catalyst of re-strcutured urbanity The conceived public transport system should translate in the context as an adaptive and integrated design entity. The infrastructure design strategy is to re-use as much existing infrastructure as possible, thus making an cost efficient project. In major spines, the design suggests to take up some space from the ROW of private motorized traffic and heavy traffic for the dedicated bus lane and at the same time suggest ample amount of user-friendly cycle and walkways; and thus attempting to retain the urban character of the major spines.

Along the A. Yani road, a secondary road system is envisioned along the main spine, this allows slow motorized mobility along with non-motorized mobility and is seen as an public-private realm conecting the street and the properties, e.g. shops, schools etc. As Infrastructure projects are usually not easy to build in one go, it phasing has been an important issue in the desgin discourse; for example, the new proposed regional road that goes along Banjarbaru also is designed with a flexbible middle spine to add the dedicated bus lane later when with growth of BanjarBaru city, the nearby settlements demands so. In this way it is considered that with the evolution of the city the infrastructure will be able to adapt and make way for improvment or change.

RESHAPING INFRASTRUCTURE IN A GLOBALISED ECONOMY From connectivity to resilience : A study on Banjarmasin

Isabelle Matton / Bruno de MEULDER - Guido GEENE Master Thesis: Studio Urban Design and Planning

KULeuven - Faculty of Science, engineering and technology Department of Architecture - 2014/2015

FOREWORD By moving away from the former autonomous figures of urbanity to a hyper-connected territory, mobility becomes more than ever an essential component for a region’s running, and conditions its degree of modernity. The intensification of cross-border trade, coming as a direct consequence of the industrial revolution, shaped a world based on infrastructural system from which is resulting a flow-orientated territory (Berlingieri – 2014). Already in 1766, Adam Smith recognised in his book, Wealth of Nations, the power that infrastructure has to overtake local economies and develop trade on an unprecedented scale.The fact is that roads and railways are linking completely different regions and nations, which allows the distribution of wealth on a broader territory and, as a consequence, scales are changed. Nowadays, as it has been called by economists, a path dependency situation is established where the urbanity doesn’t seem to have any more limit and is expanding to the whole continent. With that in mind urban footprint isn’t limited to cities but constitutes a much broader concept that goes beyond the strict border of the metropolis. Large portions of territory are now urbanised as a carpet metropolis (Neutelings)with patches of distinguished programs in which infrastructure really constitutes the glue of urbanization (Bélanger, 2012). They are as an invisible background that supports both urban and industrial activities until the precise moment when it breaks down. And this is particularly the case in Banjarmasin and developing countries in general, where infrastructure often fails on a daily basis and governments are now aware of their infrastructural needs to push their economy to the next level of modernity and global inclusion. As such we are on a turning point as designer to give more complexity to infrastructures since they are now embedded in a territorial system in which they necessarily meet multiple functions. The question is then raised of how infrastructures should interact with the context they have been inserted in, indicating therefore that they are as crucial as before, but in a new way. In fact, infrastructure has to be re-conceptualized in order to construct new forms of urbanity and the site itself. Therefore it cannot be excluded from its socio-ecological and aesthetical role.The potential of infrastructure as a tool to develop urban strategy is essential as it prepares the ground for new development and conditions future perspectives.

“In the last century, capital and power became more important than land” John Kennet Galbraith, 1967

ORIGIN OF A STANDARDISED SYSTEM Roads were originally built to conquer and reclaim new spaces and were often coming out of military necessity. Since they weren’t always maintained afterwards, roads construction had a really slow development until the outcome of the Industrial Revolution and the definitive shift from a rural-agrarian society to an urban-industrial one. In other words, Modern time means a definitive transformation from a pedestrian city to a networked city (Joel Tarr, 1988) embedded in an economic regionalization. In that context, infrastructure was seen as the ultimate political propaganda (Jo Guldi, 2012) for capitalism and democracy where the intention is to prove that technology is the solution to permanently frame the national’s trade and reduce long-term poverty. Often emerging from crisis situation, infrastructure quickly became the private hunting ground for engineers (Marc Smet, 2001), implemented as “an artefact that exist for the sake of a technical programme”1. Consequently infrastructure ended up being a technical element; strictly codify by certain typologies of uses. As for designers, they marginalized themselves, maybe unconsciously, by focusing more and more on the technology of representation (Stan Allen, 1999). “Through roughly 150 years of industrialisation we have come to believe that the politics of efficiency are beyond question and that standardisation is the ultimate expression of democracy” (K. Pool)

Quickly, with the advent of imperialist economy, industrialised countries required new sources of prosperity overseas. Indeed, with the process of globalization, production and outsourcing is mainly relocated abroad, in colonies for instance, where labour forces are the cheapest. A globalised system that seems to be an irreversible phenomenon and that Merrian-Webster defines as “the development of an increasingly integrated global economy marked by free trade, free flow of capital, and trapping of cheaper foreign labour markets.” In that process, Indonesia, as many other south-east Asian countries, became part of the worldwide capitalist system under the governance of the Dutch colony. After the creation of the private company VOC2 in 1602, the productive capacity of the country was pushed towards an exportation economy which obliged peasants to convert rice paddies into more lucrative crops or so-called cash-crop plantation. Indonesia and East Indies in general, became then the main source of raw product for the Dutch Empire, a situation that was still true after Indonesia’s independence in 1945. This major shift had a relentless impact on its economy, its demography and its landscape. Indeed, in order to support the Cultivation System3, infrastructure (roads, dams, irrigation channels…) started to be erected throughout the country to allow fluent crop transportation. Batavia, known today as Jakarta, was the capital of the Dutch colony which encouraged the development of the Java Island before any others like Sumatra, Bali or Borneo. It is only during the post-war period, after the Great Depression of 1929, that things started to change when sugar4 ceased to be the key product to be exported. Other goods took over the global market like rubber or petroleum, and during the sixties the core of foreign importation passed from Java to Sumatra, as a first step, soon followed by Kalimantan.

BORNEO’S AGRARIAN TRANSITION The post-World War II economic expansion marked the beginning of an accelerated growth of both demography and agriculture in Borneo Island. With the industrial intensification, the rural landscape and the livelihood of its inhabitant lastingly changed In general terms, the Kalimantan region is endowed with a large tropical forest cover and a dense hydrographical network. Countless rivers create a really particular ecosystem along the lowland of the coast where most of the island’s population is settled. Watershed constitutes the most important and irreducible element of the landscape, and rivers used to be the key corridors of communication between the different agglomerations. However, since the integration of Kalimantan within the national and especially the international economy, territories came to radically evolve towards being considered as an ultimate resource frontier territory (De Koninck, 2011). “The island of Borneo alone has provided at least half of the world’s total exports of non-coniferous tropical hardwoods since the early seventies and sixty percent in 1987” (Potter et al. 1995 referring to Brookfield and Bryon 1990) Productive forest Logged forest and agriculture Protected/untouched forest

Projects of wide extent have earmarked Kalimantan whose soaring economy was demanding even more cleared lands for production. Consequently the attractiveness of the region’s growth induced an important labour in-migration coming mainly from neighbouring islands and particularly from Java. In only forty years the population tripled, going from 5.4 million inhabitants in 1960 to 16.1 in 2000. For now, the current issue is the lack of internal linkage within the different provinces of Kalimantan, whether aerial, fluvial or road connection; the fact is that Borneo is more integrated into national and international trade. As a consequence, an interesting momentum is now created where the local authorities are willing to liberate themselves from the Java’s supremacy and in order to do so, one of the biggest point of investment is, and there is no much surprise about it, infrastructure. Highlight this territorial transformation is crucial to be able to project any kind of future for the region and its cities. In fact Banjarmasin cannot be envisaged only by itself but rather as an active part of a bigger geographical and socio-economic system. As Linda Pollack wrote, the site exists at an unlimited numbers of scales and therefore a road or a railway needs to include a multiplicity of uses and identities. From this horizon, we can start to see the importance of infrastructure as one of the last remaining tools for public authorities to influence and structure Borneo in a more sustainable manner, even more since private corporations are taking over the land to initiate palm oil plantations and other mining industries. All in all, infrastructure is an intricate system of politics, economies and ecology as the space where the human is linked to its broader relationships. Although economy is too often coming at the front page, it is time now to assess landscape as an active actor of urban growth structuring. Infrastructure has to go beyond its technical aspect to embody a higher level of functional complexity. In order to be truly sustainable, strategies have to include and design the social and ecological aspect of infrastructure. Figure 3 : Borneo Map where are represented its complex internal connections and economy. It clear, through that map, that extent of productive forest (rubber, palm oil...) are taking over protected area.

LANDSCAPE AS PRIMARY INFRASTRUCTURE 1_ Contextualisation of infrastructure

2_ Strategy of scale

Sprawl is inevitable as well as land speculation and the growing number of productive lands throughout South Kalimantan. For these reasons, the challenges are to supply dwellers with numerous new services to sustain the on-going urbanization. Infrastructure is one of these.

At the contrary, infrastructure is constructed and used by such a plethora of different actors that any project should support their interactions to produce dynamic relationships between them and therefore allow the unexpected to happen. To recognize the complexity of the urban condition, infrastructure becomes layered, nonâ&#x20AC;&#x201C;hierarchical, flexible, time-based and, most importantly, strategic (Waldheim, 2006). A strategy of scale definitively includes landscape as a design material where the new forms of urbanities are interacting with its surrounding, a framework that truly construct the ground by making it more visible.

Until just recently there was a tendency, in modern design, to think mobility and flows in decontextualized terms, almost as a layer un-fixed to the ground. Even more there was a general consensus about landscape that was often seen as an unproblematic background, as a void around build-up areas (Linda Pollack, 2006). This conventional dichotomy between city and countryside, architecture and landscape has relegated nature as an invisible feature of the urban daily basis experience. By not seeing landscape, you can hardly pretend to build it and, instead, you foster an architectural culture where everything is at a human and tangible scale. Furthermore, taylorist principles made infrastructure a monofunctional element embedded in a planning where everything is allocated into specific zones. In such traditional master-plan a highway often constitutes a buffer zone between so-decreed incompatible land-uses and, as such, conflicts are pretended to be resolved by simply avoiding confrontation. The outcome of such an inflexible planning is a sterile environment, limited by an obsolete antagonism in which nature is excluded. At this point we realise that the monopoly of engineers over infrastructure is inherently contrary with its essence. In fact, this hyper-professional segregation has compartmentalized landscape and urbanism in two different domains while infrastructure includes a myriad of layers that it cannot express by being restraint to one discipline.

Scale is a key to the development of urban representations that celebrates differences of size rather than suppressing them in an effort to maintain human scale, a cultural construction identified exclusively with the measurable and the known (Linda Pollack, 2006). In Banjarmasin, the water infrastructure that once structured the city is increasingly being hidden under informal lanting houses and a countless amount of bridges. In many cases, within or around the city, rivers are at the backside of settlements and almost constitute the private backyards of its inhabitants in which daily activities are realized such as bathing, clothes washingâ&#x20AC;Ś Water spaces are often relegated to individual activities and in that case nothing provides people to colonize and urbanize the river as their private territory. Although the mains water arteries are still dynamic places where a myriad of activities are happening the threat is that, because dwellers are in a need of broader connectivity, the roads system takes the lead to the detriment of soft infrastructure. Figure 4 : The growing city, along A.Yani road, sprawl is taking over swamps, considered as spaces for land speculation.

The task of planning, in that sense, is to acknowledge the water element has an instrument to redefine the urban condition as well as the regional forms. Natural processes are highly imbricated with human activities and as such, infrastructure should be designed in order to facilitate, rather than interrupts, those ecological dynamics, without however professing to be managing nature. By bringing contingency to infrastructure they will become more significant than just a line in an overcrowded urban system. Landscape-based strategies help us to integrate urban fabrics in another condition than just their selves and allow a bigger variety of identities to be enhanced. Infrastructures, by being the space of multiple scales, have the means to include cities into their broader ecological and geographical context by shape relationships between them. Hence each scale is being nested in each other (Waldheim, 2006).

3_ The imagibility of a system By being recontextualize, infrastructures show us what is behind the road and reveal the different gradients of urbanity throughout the region. For instance just by following the A. Yani road that links Banjarmasin to its foothills, we could easily think it is a dense-constructed line and that there is no transition or difference between the two cities. The reality is elsewhere; indeed the fact is that we only perceive an opaque faĂ§ade of buildings without knowing their thickness and such homogeneity enables us to truly understand the logic of the territory, its quality and character. In the same way we should act for Banjarbaru which tells us another story. Situated on higher lands the topography varies more and water is less present than in the lower lands. Again nature is changing and the interaction that people will have with it equally varies.

Therefore Banjarmasin becomes merely part of a deltaic territory with again the waterscape being the central element of its system. Urban economies are even more turned towards water with the intensification of harbour activities and canals are being re-opened as a public space that everyone can appropriate for its own use. In that frame, road and water need to find a new balance and work as complementary system without one dominating the other as it is happening now.

Consequently, the paradigm of efficiency and space rationalization needs to be substituted by design and openness. By oversimplifying a system, the collective imagination of its users is thus impoverished and the environment, by not giving the tools of orientation, is lacking character and ends up being chaotic. For these reasons, the perception of our surrounding has a great importance in how we understand cities and regions, hence any strategy should consider as a leitmotiv the stimulation of the siteâ&#x20AC;&#x2122;s experience. Regarding infrastructures, now considered as a

primary public space, they convey collective memory and makes a dynamic impression (Lynch, 1959) on its users although they also constitute a static element in the landscape. Through the different elements of infrastructure that irrigates Banjarmasin’s region, its inhabitants should be able to identify the constitutive elements of the urban scene whether it is landscape features or build-up character. To do so the notion of rhythm and sequence within the space of a road or a river is key.This linear element go across a variety of spaces and if they are comprehended by the user’s eye then decisions are easily taken and people could better orientate themselves by recognizing the specificity of their location in relation to the bigger whole. The purpose of it is multiple; it allows a sense of transition between distinctive elements as well as it enhances the image of the environment which, therefore, acquires a meaning. In Banjarmasin, integrating complexity and frequency in the infrastructural network could make people aware of the various functions and identities of the territory which is now almost vanished under an uncontrollable sprawl happening mainly along the roads. Signalling the use of what is produced in which kind of land and who is living where, informs us what the space is standing for and will eventually create more opportunities along the infrastructure than only concrete walls.

4_ The latent infrastructure If infrastructures condition people’s migration then they should be thought in terms of ecological impact rather than exclusively in terms of economy, and the strategic approach has to be integrative. Indicating the visible landscape is a first step to achieve resilience but constructing the ground is also about the subsurface conditions of a site which takes into account soil conditions, the water table, the geomorphology… All those elements, even though invisible, are part of an active system that influences directly the urban environment and that is incompatible with a centralised and dominant system of infrastructures. As such, expliciting the landscape and its latent dynamism is a way to make it a powerful and structuring element for the framing of the urban complexity. Therefore when ecosystems are becoming that essential to the urban condition, nature becomes truly infrastructural (Allen, 1999). In South Kalimantan soil typologies, as fluvio-alluival or gambut (peak) soils, are the reflection of what is found on its surface. Having tenure knowledge of those conditions and their movement shapes the way infrastructure has to be built in relation to it. In the lower lands, for instance, flooding is a main issue and any road has to be elevated on an artificial topography to ensure the good functioning of the mobility flows. However in some strategic case a road could be exaggeratedly elevated from the ground surface in order to protect urbanism from water movement. All in all, landscape starts being an integral part of the urban system whereas ecological processes are constantly put in tension with the soaring of hard infrastructures. This step is a necessary operation in order to achieve a semblance of self-generating ecosystem. The landscape is not just a two dimensional element but consist of a thick section of characteristics and systems that aggregate in the mat surface of the contemporary metropolis (Prince, 2013). Figure 7 : Throughout the city, intersection and crossroads are the space of intense activites of any kind whether it is a market or a meeting place. In suh chaotic system, the urban corners are very often place of reference for its inhabitants where they can grasp the complexity of their environement. A place of opportunity. source: personal picture from the fieldtrip in Banjarmasin city center.

PHASING INFRASTRUCTURE If nature is an integral part of the project, acting as a structuring frame, then the notion of temporality becomes essential in any strategy. By being inevitably provisional, staged and cumulative (J. Corner, 2009), landscape cannot be understand as a simple form but more as a process that evolves through space and time as it is also the case for urbanization processes. The future of a city and its landscape is unpredictable for sure and a unitary and stable project becomes therefore irrelevant. But by foreseeing a flexible and evolving network of infrastructures, we establish an element that forges permanent relationships between a growing population and its dynamic surrounding. Consequently, infrastructures should be conceived as a living matrix, which prepares the ground for evolving scenarios where new relationships are made possible meaning new kinds of activities and new patterns of occupancy (Rahul, 2011). Such contingency provides infrastructures with a sense of time

that enables the accommodation of potential unknown developments without entailing the collapse of the entire system. Very often infrastructural enterprises are of such a sheer size that their construction goes along various political mandates and through evolving visions of the territory. Indeed urbanities are the result of successive decisions that are not necessarily compatible with each other; by the vagueness of political processes, infrastructures seldom are as it was drafted or promised. Hence, in order to be sustainable, they have to integrate in their design the fact that urbanization, as ecological systems are, is an unstable and on-going process. Regarding the lifespan of an infrastructure, whether a road or a railway, as designers we have to establish what is fixed and what is open for changes so the whole infrastructural network becomes both precise and indeterminate (BĂŠlanger, 2011).

CONCLUSION Globalisation is a growing phenomenon that conquers progressively more and more regions throughout the world and integrates them into a global economy. As such, globalization is not the product of any societyâ&#x20AC;&#x2122;s tradition but rather the intensification of flows associated with the technological revolution. As it is now, we are engaged in an irreversible process and for that reason we shouldnâ&#x20AC;&#x2122;t denied it for some nostalgic reminiscences of the past and frankly engage the strategy within the global system as an echo to our contemporary system. Indeed, the urban landscape is the reflection of our time, and as it stands now, a multiplicity of actors are engaged in the expanding space of the metropolis which also suggests a myriad of different perceptions. The era of the dogmatised master plan should be substituted by an integrative approach of the landscape where the different reading of the territory reveal some inherited qualities of the past but may also be capable of repairing and clarifying the opacities of the present (Girot, 2006).

In Borneo, the projects of the Indonesian government are ambitious. A new capital city might l eventually be developed in Central Kalimantan as well as an entire network of railway lines which would foster more than ever the industrial production of the Island and its demographic growth. Changes are coming but maybe not at the extent that the public authorities are expecting to be, or at the contrary it will maybe go beyond expectation. However, in any cases, changes are imminent and the challenge is to use infrastructure to frame the territory in terms of processes of becoming (Rahul, 2011) which allows whatever future scenario to take place in a better interaction with its surroundings. Infrastructure, far away from being a neutral and monofunctional element, is a space of tension that explicit both natural and urban processes.

In that frame, the strategy of infrastructure has the potential to recalibrate an entire network at different levels of operations and avoid the current tendency towards a global homogeneity. The goal is to enhance the various identities of the landscape throughout Banjarmasinâ&#x20AC;&#x2122;s region rather that only support what is consuming it. Therefore we need to reconstruct, through infrastructure, a logical system where a maximum of possibilities are allowed and in which ecology is the primary and structuring actor. Landscape is then invested with significance and helps us to rethink the urban condition in a sustainable way where nature is not relegated to a simple void around cities. Often through history, infrastructure went to successive phases of visibility and invisibility. Progressively, in Banjarmasin, we are forgetting how things are made and thus we lose the access to our natural environment. A city or a region is never a finished product and constitutes an on-going process incompatible with a fixed master-plan; hence new strategies have to heighten means rather than ends, potentials and landscape rather than programs.

This research aim to study the complexity process of transit and land used integration in order to duel with the rapid urbanization in developing countries which specific case in Banjarmasin, Indonesia. Base on the thinking that identifying problems as important as solving those, the first part will contextualize the territory with challenges and opportunities that it contain. While in the second part, i will briefly review theory about transit and land use and relevant cases in the similar context.

1.Contextualize territory: Context

Source: STUDIO

In the rapid development context of Banjarmasin in specific and Kalimantan Island in general, the governmentâ&#x20AC;&#x2122;s ambition is to gain more economic independence from Central Island in Java. Numbers of projects are planned or under construction for better internal connection such as: extension of existing regional road Trans Kalimantan, setting up new rail way system for both industry and civic purposesâ&#x20AC;Ś There is a possible scenario of having a new capital in Central Kalimantan.XXXXXXX These economic driven forces put a pressure on the existing urban system and raise a question of a sustainable development in the future Nevertheless, in general, it is seemed like that every road similarly attract the same urbanization along them. Policy exposes its exceptions and loopholes and implies to accept these growths like simply adjusting the deep of limitation through time. Little regulation gives priority to the private user (car and truck). But basically, this means that every road will rapidly get congested and indeed starts obstructing the traffic flow. At the moment, the only way to solve this problem is adding new roads which again lead to a similar future. As such the territory is filling with every new line that is drawn and urban sprawl happens everywhere cause the losing of agricultural land natural environment In the scale of Banjarmasin city particularly, the impact of mentioned tendency is economic growth, population, urban quality and traffic congestion. Ring road and satellite city are not a compromising solution which not only cannot solve the problems rather than upscale them. Indeed, mono functional approach and standardize design without taking into account the role of ecology as well as social aspect is raising a question of resilience of the plan to duel with uncertainty and unpredictable events in the future.

Cities for Cars, Not for People Automobile dependent development is one of the biggest challenges for cities worldwide. Duel to economic growth, as many cities in the developing countries, Banjarmasin have a trend to repeat the trajectory of developed countries with a much quicker speed. Economic growth, rising incomes are encouraging car ownership. There is not only a shift from water to road but also from less or no motorized transportation to private car or motorbike. Using their car, people can both reach labor, education and facilities in the city as well as having a larger lot in suburban. I think it is true to say that if we plan the city for cars, we get the cars. Many problems such as uncontrolled urban sprawl, adjacent land use, unfriendly pedestrian and low urban quality, pollutions… is an avoidable in an automobile oriented plan. Barcelona and Atlanta case: One of the key elements of sustainable development is guiding development and restrict low-density urbanization. The diagram show big different in footprint of two cities Barcelona and Atlanta which have the similar population condition of 2.5 million in 1990. However, Atlanta have a built-up area which is 26 times bigger than Barcelona’s one. Preserving green spaces is an opportunity provided by less built-up area. Moreover cost of extending urban infrastructure, roads maintenance, transportation operation, waste water and sanitation, energy distribution are reduced by less sprawling development

How land speculation contributes to sprawl

Facilities development created by transit infrastructure server for a given number population and commerce. Urban sprawl happen is not the fault of infrastructure itself, but by the way landlord can explode the extra value create by public investment. For example, normally land value in the area around metro or BRT will increase after the project implementation, the land owner try to keep the sites and against integrate with land use. The worst thing of this land holding action is creating motivation to develop cheaper neighborhood which lead to urban sprawl. Because once this kind of cheap land is filled with inhabitants, they usually create political pressure to have infrastructure extension for serving their area. Once the extension of infrastructure happen, hand in hand the land price of those remote and cheap areas will increase. Then the similar trajectory happens with endless urban sprawling. This type of sprawling development is characterized by non-contiguous land use and low density which confine the slow movements and transit while increase the need of private automobile and lead to many other problems.

1.2. A latent urban system

Source: By Author

Banjarmasin and Banjarbaru, the two cities which have different character, vocation, pattern and activities inherently work as complementary structure. The urban system was there but wasnâ&#x20AC;&#x2122;t exploded it potential and nowadays there is a threat of saturations that they are growing toward each other. With the growing of population, unclear identify system is high risk to become a chaotic mess like what happen in many developing country. Therefore, infrastructure should seek the chance and be a strong statement to keep two different identities and enhance them for a stronger complementary system

In order to reducing the trend of urban expansion duel to automobile dependency and placing cities in developing countries in a sustainable development, transit and land use integration is one of the most compromising instrument. BRT systems particularly, is consider as the majority of urban development in the future are expected to take place in medium cities (cities with less than 500,000 people) (UN Habitat, 2011) with limited financial capacity. BRT systems, which can play a role as metro on the ground are much more less expensive than it and other forms of public transport, can meet the needs of the city traffic. During the last decade, over 130 BRT system began operating, promoting TOD will be especially important to duel with contemporary challenges such as: unpredicted growing population, concentrates the population of a city and reducing the demand for private vehicles, protecting natural environmentâ&#x20AC;ŚAlong with it, politicy, regulatory and support mechanisms for rebuilding built up areas, particularly brownfields or abandon area which is neglected urban design in the neighborhood and street level as well as financial constraints Using case study method, this paper try to draws on lessons learned from global case the best example of the large urban navigation related directly to cities in the developing world and other place that is currently invested in bus rapid transit (BRT) or other high-capacity transport. There are two interesting case of rapid development and motorizing cities that introduce BRT system expansion: Curitiba, Brazil, and Bogota, Colombia and contribute to understanding of the important factors for â&#x20AC;&#x153;city transfer with transportation.â&#x20AC;?

Generally, cities, especially cities in developing country, take on a polycentric form when they grow. So that the task of connecting these high density centers which could be business district, residential or mix-used area… by a good quality transit is very important. Interconnection between mix-used urban centers with high capacity transit not only create two or multiple flow but also harmonize the flow and travel demand be more evenly spread out whole day. In the case of Curitiba, Construction of transit oriented was stemmed from a good urban planning. Early in the planning process, the leaders of Curitiba provided a master plan that search out the way to channel the growth along designed corridors with mixed land use, densify land development around BRT stations, and introduce a high quality system to encourage pedestrian access to BRT corridor. Bi-articulated buses operate alongside sidewalks and slow-speed frontage roads. Ground-floor retail on the lower floor of buildings and upper-level office and residential space—set back several meters to allow sunlight to reach the street level—creates a rich mix of land uses along trinary corridors. The inclusion of mixed land uses and affordable housing allows developers to increase building heights, adding density to the corridor. Streetscaping enhancements have created a pleasant pedestrian milieu. Frequent-stop, biarticulated buses operate on the mainline of the trinary corridor; limited-stop “speedy” buses flank parallel one-way roads. People traveling longer distances often opt for the limited-stop buses, whereas people traveling shorter distances or going to destinations bypassed by the speedy buses usually patronize the mainline frequent-stop services. The market has responded to this rich, differentiated mix of bus-based services along the corridor with high-rise development, supported by zoning and public improvements like sidewalks and landscaping.

Bogota could experience another stage of transformation by addressing the strategic development of space with transit improvement. For areas that are less developed, nodes of planned public transitâ&#x20AC;&#x201D;metro lines, regional rails, or the TransMilenio extensionâ&#x20AC;&#x201D;should focus on shaping space to accommodate increased density with varied building heights and mixed-use zoning, as well as creating pedestrian-oriented areas with sidewalks, carefully articulated streetscapes, and parks. The redevelopment of areas along the TransMilenio system should be promoted through modified land-use and building regulations to obtain increased building volume and strategic land use.

Lessons and principles:

Nevertheless, most of the above cases were reviewed by people from developed country. Without some adjustment or adaptation to local realities, it’s very difficult to apply their experience in developing country context such as Indonesia. The goal is more to define the key principles and core lessons can guide the planning and implementation of the city which aim to plan or invest in generation massive transport systems Looking at the case of the city has been actively investing in public transport systems highlight the context and challenges of transit and land use integration. Generally, the experience gained from these cases of policy recommendations and implementation measures should be carefully considered in different levels and scale of strategic decisions and planning exercises. For example is creating a supportive institutional and government environment, removing the restrictive regulations and set appropriate land prices, exploiting the implementation process, focussing on social development in TOD (make cities inclusive), creating a sustainable finance through value capture... and other the institutional framework and regulations. But in this paper, i will mainly focus on what lessons and principle of design that should be taken into account of integration between transit and landuse One of the most importance principles is develop a strategic plan. A strategic vision is prerequisite for success of integrated transit and urban development. Transit helps to create the expected pattern of urban development. It links people to place literally and figuratively, so it is a mean to form the type of city and the area around it. Their vision of the future on land use as well as other infrastructure elements should be made clear by law which have to be market sensitive, socially inclusive and base on financial reality. In order to duel with uncertainty and unpredictable context. short-term mobility objectives parallely go hand-in-hand with long-term sustainable urban form goals. Experience from global cases is that investing in creating more roads and transportation infrastructure to improve mobility in the short term eventually leads to more problematic in the future. This is what is called “induced traffic.” Transport decision should be carefully consider in both term of supply and demand perspective. By itself, supply-side expansion often provides precarious solution and again follow the previous trajectory. Successful integrated spatial development can have to provide both near-term congestion decling and benefit the longer-term urban transformation. Effective integration is not something planned once and automatically happen, however; it requires strong leadership as well as testing and adjusting through time.

Create articulated densities. In simply speak, mass transit needs mass. To be successfully applied transit integrate land use, it is neccessary to promote higher densities along transit-served corridors to ensure a critical flow and destinations, thus increase cost effectiveness. How densities should be oganized based on the relationship with high-capacity transit services, not average densities as usual Mass transit system need to be combined with high densities with diverse land uses and pedestrian friendly design. By itself, high density is not sufficient for sustainable urban development. Many experience shows that in order to promote sustainable travel and city form, highy density must work with diverse land uses, public spaces, and pedestrian and other slow movements. Particularly important are “green connectors,” which provide perpendicular bikeway and pedestrian way which link to transit stations and surrounding areas. These interventions can shorten trip, increase transit use, reduce automoible need and encourage people to use non or less motorized vehicles. Creating TOD typologies is also significant. , based on realistic need and market assessments, Cities in developing countries need to build a typology of transit systems which is different in scale, profile, type of traffic, rythm and speed, integration or separation of traffic modes. A diverse portfolio of plans and layouts is more effectively respond to market realities and regulatory factors

In order to be sustainable, infrastructure much enhance the quality of landscape. Therefore, infrastructure engages creating architecture, making landscape, and setting up living environment. Located in an tropical deltaic environment, ecological systems and it related issues such as weathers, flood, droughtâ&#x20AC;Ś is one of the iindispensable aspect and play an foundational role to build our strategy as well as the back ground of every actions. By the other hand, dueling with existing issues and preparing room for future urbanization go hand in hand with water management. Since the moment, the infrastructure plays a role to not only guiding the urbanization but also act as a tool solve the above issue at the same time. It includes new urbanities shaped and formed by local ecosystems (Pierre BĂŠlanger, 2011). Moreover, it can also give conditions to the city and open up new possibilities and potential

Resilience and flexibility

Firstly, project aims to steer urban development, both of urban or regional scale, and opening up an alternative function to a busy and overcrowded road system of the city today. Then making a clearer hierarchy structure, identify different road typologies in scale, profile, type of traffic, rythm and speed, integration or separation of traffic modes…will provide various ways and opportunities to interact with the city and landscape. In a large scale level, the goal is to go beyond the strict footprint of a road and see how the infrastructure could be de-designed and therefore obviously ecological, landscape tangible and intangible of water, spices, terrain.... in terms of flexibility and resilience. That way, “the landscape is the most flexible strategy of infrastructure” and the connection system is embedded in its environment.

In order to transform the existing system, few actions of cut, add and profile in some strategic point which will have the impact to the system as a whole. Thus, by those means we deny the double system, with its mono-task, qualities and rhythm but keep in mind the operation of ecology system, especially the water. 3 systems with its own character and functions have defined a clear framework for the future development: 1.Transkalimantan â&#x20AC;&#x201C; the regional system: This passing system that was already merged with the current urban structure. It ensures the continuity between the different parts of the region and is characterized by a landscape in which it is embedded. Essentially the line is something more than just linking program, it also play a role a structure, a bridge or a dynamic filter for the ecology and urban activities. Specifically, the line adapts itself to the terrain in higher ground and create an protection for Banjarmasin urbanism from flooding, defining different type of landscapes and enhance boundaries between them. There is an approach to multi-route direct to the water line or build a bridge across a landscape that needs to function as if the road was not there. (All in all regional lines are usually located between two different conditions of soil and land use and disclose a basic condition of the territory.) 2. The train system - a possible hypothesis : There is a big investment in transportation especially the railway system used for both people and goods transportation. It shows the governmentâ&#x20AC;&#x2122;s effort to have a more independence economy. As many other economic driven thing, the cost of such huge infrastructure and its impact in the context can be horrible. By contrast, putting it in the right location is very important for the implementation and support - as well as in case of regional lines - Waterscapes and urban development. For now, this is an extra step in the far future but the system should work with or without it.

3.The urban system: It includes network of public spaces and different centralities of the three cities: Banjarmasin, Banjarbaru and Martapura. The network provides space and social life of the community and therefore is designed for people in which they can live, work, play, learn, and interact. It give the priority to the people, not for the efficiency of the flow. In contrast, the profile of the street as well as the river is characterized by a denser rhythms that enhanced through urban activities, either officially or unofficially. The main idea is to promote the local identity of the city is developed with specific characteristics The system have another important task as a superior system of feeder services, enabling a smooth transition and connection and seamlessly between different modes of transport. For instance, trunk-line services provides economies of scale; feeder service with smaller vehicles, such as minibuses, waterbus, boat and small ship provide economies of scope. The two modes can be highly complementary and be integrated with extensive urban railways that provide interisland connections. In major cities, BRT systems and local buses is essential that decrease use of cars usage. Physical link non-motorized transportation with dedicated bus lanes on the main road and a system of slow movement as bike and pedestrian that link to public transport nodes, for example, is an essential part of a transport network of interrelated and possibilities contest that offers mobile options for private vehicles.

Banjarmasin is transforming care from an emerging car-city to a reactivated water city. The use of water resources is enhanced not only as a means of public transport, but also a public space and back in front of the city as a generator of new urbanities. For excess of the infrastructure is planned with such ring road, the space is recycled to be integrated in the public sector. oIt still keep itâ&#x20AC;&#x2122;s on character of traditional city, markets city while avoid the urban sprawl surrounding and maintain connection with new room for urbanization in Banjarbaru by high quality transit system of dedicated bus line. On the other side, Banjarbaru - the â&#x20AC;&#x153;planedâ&#x20AC;? city is now expanding toward the south where have highr and more stable land condition.With that in mind, a new line in the area had been done to help frame its growth and support the development of activities in the mining sector on the conversion sites. In order to duel with the uncertainty in long future, the character of the area is flexible and can be developed into an urban boulevard, a spine for the city if necessary in the future. Banjarbaru serve as a counterweight to reduce the pressure for Banjarmasin and taking benefit from it thanks to the strategic location In between the two complementary entities, A.Yani line is getting a new meaning to the link between different identities as such it need to be transformed, re-profiled to serve this purpose. In A.Yani, but also in the overall urban system, little space is provided for private motorized transport and heavy traffic. Therefore, the scale is adjusted and the shaft is intended more for intercity and local movements.

It seem that infrastructure projects are always on over scale and decisions to set the order of actions is extremely importance, other while good strategy with inappropriate step can lead to another scenario. By contrasts, once strategic parts be done can affect the whole system and the rest will come as consequence. By doing so, we consider the development of both the landscape and allow urbanities and infrastructure in its self-adaptation to changing conditions. Therefore, thanks to the clear strategy that guides the whole system, decisions in strategic nodes May be lass decisive but it would be a very interesting ways to testing the potential and practical reflection of how infrastructure decision can transform the landscape and cityscape,

3. Conclusion Conclusion During the project, the goal is to have an adaptive and integrative strategy in which the complexity of the territory and stakeholders are taken into account. By this way, it is possible to introduce a new kind of urbanities with its diversity In that sense, the strength of the system lies in its multi-function which produces a matrix of life where nature is unrestrained in a network infrastructure but involve in a system that several of different development may occur. Thus, the role of infrastructure is not only to support the national economy, but also structure the social and ecology. This strategy is not just about the hierarchy of road system but also about different in scale, typologies, Profile, rhythm ... Therefore the infrastructure go beyond simply of a line, but adapted itself to the different identities of urban system as well as various of natural condition. It enhances the difference intensity of the territory and the emptiness is as important as building environment.

Towards a generic city? Banjarmasin portrays itself as a city of thousand rivers. Nevertheless, nowadays the identity of the city is weakened by its deprived environment and it is threatened by the implementation of generic solutions properly fitting a good city. Also the upcoming position of Banjarbaru adds a dual relationship. Looking deeper, the city has a rather homogenous tissue which isnt able to serve the inhabitants and lacks an embedment in its natural landscape. The rapidly spreading new developments are an instance of this. They lack on providing all the needed services in order to function within the current community system. Banjarmasin has to potential to stay a capital city for the region thanks to its strategic location and trading position. In order to guarantee a stronger position for the city, the border with its hinterland opens opportunities. Although at first sight it seems again very homogeneous, it is a void offering a variety of characteristics. Decomposing the landscape according to its main layers, different (edge) conditions and principles can be picked up as guiders for future development.

TOPOGRAPHY & WATER - Higher ground define the possible urbanisation areas. Nowadays, there are already multiple zones brushing aside the landscape condition, resulting in trapped water bodies between the land fills. During possible flood situations, multiple areas in the city centre are affected.

GREEN & PRODUCTION - Forest structures are mostly found on higher grounds. The lower areas are productive rice fields, leaving the lowest areas to emerge as swamps which potentially can be productive in terms of Gallam wood production.

TISSUE, FUNCTIONS & CONNECTIONS - Most of the functions, especially commercial are positioned along the major connections routes. Small scale services are spread out according to the dispersion of communities.

City of Banjarmasin, Linear settlements along the river. 26

[Re] Defining the Indonesian Urbanity, the Linear City as Urban Structure: a study on Banjarmasin Author: Amaranta Vargas Mendoza Key Words: Linear Structure; Urbanism; Corridor; Indonesia Abstract Banjarmasin and Banjarbaru are two of the key cities in the Banjarbakula region, Banjarmasin will be the studied city for this project and this research paper taking in account the final design as a conclusion for the studio work. This paper will review multiple linear cities in different contexts around the world, from concepts to real proposals, like Soria y Mata, Le Corbusier, Garnier and others, to support the final design project. In Banjarmasin, Indonesia, urban settlements start developing along the rivers and the canals, taking the water as the main transport system since the beginning of the city. The ordinary settlements along the river can easily symbolized the birth of the linear urban structure in Banjarmasin. Now days the road appropriates this new concept, becoming the main axis for settlements, commercial activity, industries, storage, etc. this recent outcome for developments along the road make us reconsider the linear concept as a working urbanity in the Indonesian context. Our proposal for the new urbanity in Banjarmasin takes the main advantages of the linear structure. The shifting of the existing infrastructure to work as an urban corridor, a control of the growing population that allows it to expand, and efficient public transport for movement of people, a secondary mobility line for the movement of goods. A good transportation and connection to the different emerging urbanities in Banjarmasin and Banjarbaru becomes in the main purpose to tackle in this project. The Morphology of Indonesian Cities The history of the Indonesian cities is very complex, the Indonesian context presents diversity in all its forms, beginning by the cultural groups and follow by its territory, and the different cities are a reflection of this diversity. The tradition and the religion are strongly related to the urban morphology and this is the character that defines some of the settlements, the cities were found due to diverse reasons, as a production center, storage or trading. It has become in different urban forms that have been changing though time. One of the strongest traditions could be the coastal trading, making the cities that are on the coast mostly a provincial city. The European colonization, mostly Dutch had a big impact in the form of the Indonesian morphology, with the imposed landscapes in a very different habitat physically and culturally. This change in the existing environment brought various problems as the city start growing, bringing diseases for the lack of open spaces compared to the Dutch amenities. The colonizers were in control of the cities but not many of them were living in the cities. Many Chinese immigrants were attract for the industrial and commercial activities that represent a big support for the different cities. Chinese introduce their own scenery with small shop houses unlikely adequate for the Indonesian context. In 1700, a normal city in the Java region was compose with a nucleus similar but not quite to the European model, a Chinese town and other Asians societies involved with the trading activity. After the outskirt of the cities, the Java homegrown community produced goods and labour to the cities. Close to 1800, Europeans were abandoned the city centres by the difficulties of the swamp areas and the original settlements to urbanized, looking higher lands far from the original centres, a city model that appeared in Jakarta. In the city of Jakarta, another node was developing next to a bigger one. This area was a military ground a few kilometers away from the initial settlement. This new node had the advantages of drinkable clean water, far away from the zone of saline intrusion and from the fetid canals inside the city. With one road that traced the path for houses and government buildings while connecting the new community with the old district. This new community became in the elite newest residence for Europeans and for important people in the government of the old city. The Chinese appropriated the townhouses in the former city; this became the new shop houses. Meanwhile the urban ideas were changing; the government elite community was building enormous town houses like the European latest trends, farther more the needs for pleasure and health were more important than the defence. 27

Jakarta was establish as a linear structure by 1800, with 8 kilometers strip with 1-kilometer wideness. Therefore, in mid-1800 Jakarta had a dumbbell shape, with the old district with the port towards the north and the new district for European urban areas in the south. The axis that connected these two districts grow into a wider area, with the kampungs (Javanese settlements) filling this urban axis, this new axis filling became a model for the future Indonesian urbanity, by the mid-1900 Surabaya and Semarang adopted the same structure and started developing like Jakarta patterns, but some changes were made. For example, Medan one of the newest from these cities, start growing down river with the agricultural landscape that had a connection with the port. Until 20 century most of the cities in Indonesia continue with a small and compact growth. The idea of the Linear City The linear city structure has been appearing in the history for quite some time, even before the linear city theories in planning started in the modernist urbanism. Unplanned linear settlements in the past has follow the planned linear city in the present. Arturo Soria y Mata One of the most important pioneers for this concept was Arturo Soria y Mata; he was an urban planner from Spain. His concept first appearance was in an article in Madrid famous journal of the time, where Soria tackles the municipal policies of planning, advising a radical measure for the future planning of Madrid. The Linear City concept had as principal idea one strip of 500 meters wide, the long of the strip would be the necessary, by necessary we mean it could be as long as the city would require. In the center of this strip, the main actor would be the train line and tranvia. Main pipes for water, gas, sewage, electricity etc. Every certain distance would be building exclusively for municipal services, like fire prevention, cleaning, sanitation, security, etc. In this concept, all the problems that an urban life carries would be solve all at once. The linear city project brought together all the hygienic conditions of rural life to the urban life, with a free transportation system serving all the inhabitants. Soria talks about the ideal form that the cities should adopt, supporting his theory in naturalistic and geometric reasoning that points out the spontaneous grouping of building in linear series along the road of the suburban cities. He recalls “ ruralized the urban life, urbanized the rural life, this is the problem and the solution is the Linear City” . In his argument, he compares the garden city and the linear city, implying the lack of attention that the garden city has for the transport lines, curve streets that are more expensive and inefficient and that this perpetuate the concentric arrangement of land values. Meanwhile the linear city make the transportation the main objective into its consideration and the advantages of metropolitan life are couple with the contact with the rural zone. “ A system of urbanization is not due to chance, but the product of an invention and results of a study” . It discusses the justification of his idea from the simplification and rationalization of the traffic situation, which, in turn, determines the pipes of urban services reinforcing the aspect that the linear form is the most favourable to the needs of locomotion, and how to achieve it, quickly and with least fatigue as possible. Soria’ s idea was to trace the railway line looking for the softer pendants and spacious curves and along the railway or tranvia line to situate the main strip. The importance of each capital city would be noticeable by the ample length of the main strip and for the most active locomotion, this means by the number of trains or tranvias in the centre of it. This last idea seems to show several important things, it points out the importance it has had in ushering in the idea of linear planning, a certain magnification of the railway and Soria’ s past experience and dedication to urban transport problems. It shows the sharp focus to the problem of public transport, anticipating the importance which public transport has acquire in the present. Another important point from Soria is the justification on the clean air mater. His critique on the modern city leads him to propose, anticipating the hygienist trends from the later urbanism and planning, a first garden city figure regularized in rectangular blocks of 300 x 200 meters, with isolated buildings surrounded by orchards or gardens. He addresses the problem of soil, taking in consideration the essential difference between the new city and the today city, the price of the land will varies in a different way. In the big metropolis, the highest price is on the centric location, and the price continues decreasing until the labour lands without any sing of urbanization. In the Linear city the highest price is not in just in one point, if not in a whole line of indefinite extension. Therefore, with balance prices that will decrease easily depending on the distance from the railway along the transversal streets so instead of concentric circles that determine the price, it will be the parallel lines from the railway, acting as a spine for the new structure. By this abrupt transition of land prices, rich and poor will live together, in comfort, but not bound in a single ladder and superimposed, all will enjoy their share of land, but without infringing the dignity of the citizen, which is affirm and strengthen when their home is free and independent. Regulating the price of land by a line of hundreds of kilometers, rather than by a central point, he solves many difficult and complex problems or society. 28

Every certain distance on the main strip, close to the railway line, a kiosk with multiple services would be build, emergency telephones, waiting rooms for travellers, security agents, first aid equipment in case of accidents, storage for luggage, almost every public service with an urgent character. As mention before along the two lanes, open ditches with half a meter deep would be position, which contain the pipes, tubes and cables required for distribution of water, electricity, heat, power, gas, etc. The central pipes will start to surround other blocks, and these pipes would supply services for each house. One main strip with double railway in the middle. Secondary streets transversal and perpendicular to the railway that circumscribed the blocks of 40 to 50000 square meters, inner the blocks the new housing would be isolated and separated one from another. The housing with the facade to the main strip would be for the high-class inhabitants, middle class would be in the housing with a facade towards the secondary streets, leaving the low class inhabitants more separated to the main strip. Leaving the big central spaces to all the collective character buildings, industries, storage, markets, religious buildings, theatres, museums, schools, etc. All this general theories entangled with real the Linear City itself. During its construction some variations were introduce according to some details, one example is the size of the blocks, with dimensions of 100 meters towards the mains strip and 200 meter towards the secondary streets, with some regularization that obligate to the developers to not exceed the fifth part of the area with the construction. In summary this are the fundamental principles for Soria's Linear City. The first problem to be solve and where all the urbanization problems emerge, is the locomotion and the communication, in every agglomeration of housing, without minding about the number and the importance of this. The perfect structure of a city would be where the amount of time invested in each house to go to all the other houses be the minimum, as happens in the linear city. This is the reason why the structure of the cities continues transforming unconsciously and instinctively; adapting with great difficulties and expenses to the means of locomotion, because the structure of one city is based on the locomotion means. According to Soria, the structure of the city would have to be just as the railway structure, linear and long. Another important issue to be tackle would be that the planning and drawings of the city would precede the construction of it. Just as a plan for the construction of a house is first, the trace on the terrain of the city should precede its construction. The geometric form of the streets and blocks would be preferably a regular form; this was in the means of visual attraction, for being more comfortable and cheaper than the irregular forms. It follows logically from the previous two fundamental principles that form in the city should be to a main road axis or backbone of the urban organism, the greater width possible in the central part of two or more railways previously constructed, if possible electric. Regular geometric shapes ,squares, rectangles and trapezoids , are more perfect and with a shorter perimeter that other irregular surface, therefore, it is evident that the parts or city blocks must be determined by lines perpendicular to the railway line main Strip. Separated by 20 meters, at least, where cross streets, making water pipes, gas and electricity and other municipal services would be built through parts or straight parts crossing at right angles with more economy, ease and perfection rather than today's cities. The subdivision of the blocks in parcels would be perfect and economic adopting the same squares, rectangles and trapezoids when there is not a precise block for universities, industries, markets, parks, or any other urban facilities. The division of the area would be 1/5 for housing and 4/5 for urban agriculture. The public or private facilities, under any circumstances would occupied more than the 1/5 of the plot area or the block for construction. The rest of the plot would be specifically designate for agricultural means, gardens and forest. The minimum surface for inhabitants cannot be less than 400 square meters, 80 square meters for small shops and 320 square meters for animal husbandry, orchards, fruit trees and garden. The independence and interaction between the houses and inhabitants. The Linear city has a formula of urbanization applicable in every single part for example for every family there would be a house, a garden and orchards. The double alignment was a principal too, meaning that the alignment between the streets, the sidewalks and the alignment of the housing most be a minimum distance of 5 meters that could be used as a garden or art display, not just for visual maters but for preventing the future widening of the streets. The triangulation, the rational architecture of the hygienic cities cannot pass by from the plane to the real life, crystallizing in visual and tangible facts, without adapting to the environment and landscape, created by the geography and the history. The best intermediate point where old cities; where the price of the land decrease according to the distance from the centre of the city with concentric form, can interact with the lineal cities; where the value of the terrain decrease according to the parallel lines from the railway on the main street, is between making connections between the current cities or centre cities with the linear cities. The linear cities will configured a network in each country of triangulations where the area or surface of each urban triangle would form the vertex of the centric cities, and the sides along the linear cities would be dedicated to industries and agricultural activities. The difficult intersections like where rivers and mountains emerge, existing urbanisation settlements, check points, or any other circumstances, the wide of the linear city would be reduce to the precise measure for the railway lane in the difficult

intersections. The Linear City would have a big comeback to the rural face, with all the benefits and conveniences of the urban life. Tony Garnier Soria y Mata motivated to other famous authors to reexamine the concept of the linear city, one of them was Tony Garnier and his proposal of the Industrial City. This new concept would be occupy by 35000 inhabitans, this new community would be settle in a plain are cross by a river. The main industry would be located in the plain area, by the ends of the river dedicated to textile and metallurgy an easy connection with raw materials and means of transportation. The main railway line would be between the town and the industrial area. The city would be in higher level than the industry area, on a plateau, and even higher, the sanitation facilities protected from the environmental changes. Every single element from the new city, the industrial zone, the city, and the sanitations facilities would be isolated. The different sectors area energy (hydroelectric plants), health (hospitals), industry (textile and metallurgical), housing, transport (railway station, bus station), that were isolated to be possible to expand in the future. The primary materials to the construction of the city would be concrete and iron. The industry would be separate in high-risk zones and green areas that controlled the harmful gases from the different industries. At the same time, some important regulations were created for each sector of this Industrial City, sanitation, edification etc. The most important points for the edification in the housing zone would be that the bedrooms should have at least one window facing south, the housing areas would be projected in rectangular blocks that would count with green public areas. All the primary schools would be located in the sector while the high schools or higher education institutions would be established in the industrial sector. There would be no courtyards in any housing project. From the total plot, the construction should occupied half of it, in housing and public facilities projects, the rest of the non-occupied area in the plot would be assignated to green open public space and pedestrian areas. Le Corbusier Other proposal for the same kind of utopian city was the Contemporary City by Le Corbusier, able to shelter 3 million inhabitants, this proposal for the center of Paris, promised to increase the capacity of the urban areas, but at the same time to improve the urban environment and the efficient of the city. The main aims for this new project was to improve the communication systems, to improve and increase the green open areas, a better ventilation and sunlight and reduce traffic jams. Introducing the high-rise buildings as the ultimate structure to conceive this aims and attend the increasing urban population. The design of this new city was symmetric in the center, which was the hub for the public transportation systems. The central terminal is a point of access to the subway at the bottom of the deck of the underground system. The surface plant is open to cars and taxis. The central part is reserve for 24 skyscrapers. The skyscrapers would have the dimensions of 190 meter for 190 meters and they would be higher than 200 meters. This new area would become a centrality important for all major companies. Around the skyscrapers, there is apartment blocks that offer accommodation for people working in the skyscrapers, in this apartments each one has its own garden. The area would represent the 15 percent of the total surface of the Contemporary city; the inhabitants would have a large amount of garden and green areas. There would be a business district, residential district, and the basic transport and street shops are arranged where all the elements work together. The skyscrapers represented the way of construction in the business district; meanwhile residential district is formed for 3 blocks of houses. There were 3 versions of the skyscrapers, the most impressive change was the one design with widely sawn forms, that benefit by forming traps lights. Although the contemporary city fulfil the dream of skyscrapers and building blocks of le Corbusier, with open green areas, it lacks of the urban order that the other proposals had. Conclusions After the different theories and projects of the linear cities in the 19 century, we can find why this morphology has been the source of endless discussions. Starting with Soria y Mata proposal and finding good answers to the different issues that he raises, and we can recognized that the linear city could be adapted in different context, providing a fast connection and ways of efficient transport. This concept makes a strong argument in urban structures presenting the promise of being applicable in the future. In the city of Banjarmasin, we adopt this concept for one of the main connections between Banjarmasin and Banjarbaru following some of these theories and applying new ideas according to the landscape and different built context in Indonesia.

DESIGN THESIS

WATER URBANISM

RIVER & ROAD AS WARP & WOOF CHOREOGRAPHING RURALITY INTO A NEW CENTRALITY In search of supplementary systems in a growing city: a study on Banjarmasin 2015 K.U.Leuven, Master of Human Settlements, Master of Urbanism and Strategic Planning

Case study: Martapura Lama With the vision of serving the city as well as serving the traditional way of living, Martapura Lama Road and its intermediate space starting from the Martapura river has the capacity of being transformed into a new centrality. As stated before, being the oldest settlement along the river and having the lackadaisical lifestyle adapted with the ebb and tide of the river, most of the people depend on its surrounding productive landscape for their livelihood. The Martapura Lama road cutting straight through the landscape as a connector of two nodes, one in the city and another along the irrigation channels houses small-scale business like brick industries, food shops, chicken farms and other commercial activities. However, big patches of landfill have started to appear along the road as an indicator of urban sprawl. This puts the intermediate productive landscape in the risk of being consumed by the housing, just as many other spots have been in other parts of the city. Under these circumstances, to turn this place into a valuable asset the vision must seek to create a framework that reinstates the traditionalism along with creating new spatial qualities and opportunities of employment, introducing water-based recreational activities. All these steps can therefore breed diversity without destroying the innate merits of this area. Based on the notion of water urbanism, the aim of the design exercise is to examine how the micro-stories can be changed in a sequential way by taking up relevant design strategies. In order to do that, a water-based approach of development has been considered to advocate a resilient system to work with the nature and the economy. By sharing common platforms of facilities, the new can meet the old while building an image of traditional, cultural and artisanal identity. Strategy 1/ River as the guiding system The Martapura river has always been the guiding line along which the settlements have gathered themselves. People residing in these settlements hardly bother if the water level of the river rises with the rain or tide. Accepting it as a part of the natural lifestyle, the inhabitants have adapted themselves according to the harmony of water. Profiting from the flow of water, the households orient themselves in a linear way facing towards the river. This typology is an important aspect to underline along with making them more resilient against the growing tide by increasing the height of the stilts. The mosques being placed as dots along the river, the linearity of the system becomes more obvious, which is one of the strengths of this system. As the investigation of urban tissue has suggested before, these households often appeared following 21

a clan system where the families of a main house came into place one by one. By keeping the villages in their forms and upgrading them, a generic development along the riverside can be resisted. Thus protecting the river as the main source of desakota life and meeting point of communities is a vital strategy to keep in mind. Strategy 2/ Cleaning, harvesting and linking the water Being the most important element in this system, water has manifold dimensions in this area. In regional scale, this area lies in an important crossroad that can purify and retain the upstream water in a natural way before entering the city. By cultivating a forest that cleans water also engenders a micro-climate which is suitable to protect the ecological balance in the area. The area also offers a strategic location to retain and reserve water for the summer which is usually â&#x20AC;&#x2DC;too muchâ&#x20AC;&#x2122; during the monsoon. These water reservoirs can be of different scales to feed the agriculture, the city and the communities. Several missing links among the waterways can be connected to assist the capillary web-like spreading of water in the area. The traditional agronomy converts into more effective landscape while water systems turn into filtration machines. Strategy 3/ Intensifying the production and trade Having the aim to balance the consumptive and productive landscape, this area can be the ground to boost up the production as well as reemphasize the small trades and artisanal qualities it possesses. An additional layer of eco-tourism can be introduced by locating the trades in clustered villages where the manufacturers can not only fabricate their products but also have the chance to showcase and sell them to the visiting tourists. By hosting an environment that fosters living and working condition, the ecological footprint of every inhabitant is also decreased this way, which is a prerequisite of sustainable living. Along with the existing brick industries, fruit plantation and paddy fields, the sasirangan production, sago rumba, ketupat making, sagunwood and other start-up businesses in local scale can be housed along the Martapura Lama road. Additionally, intensifying the production in the existing agrolands that makes use of multifunctional production in one land and take advantage of the timeline of the productive seasons can feed the supplementary density in the area. For example, people who work on fields for a certain period of the year depending on the weather can interchange their vocations by cultivating more than one crop or taking up small-scale trade for the rest of the year.

Vision of the Martapura Lama Road grown as a new urbanity

Strategy 4/ Water as a mode of transport To facilitate the growing industries along the Martapura Lama Road, a route of water transport can work as the economic corridor. Benefitted from both the water and road system, the businesses can take place between the two infrastructural systems. Water as the heart of life and economy, a public transport system based on water can only reiterate the significance of the aquatic existence of this region. By digging and dredging the new channels, a better water transport can be established by cut and fill process, ensuring a better connectivity. Strategy 5/ Providing platforms of interaction Nestled on a small footprint, diverse living-working and blue-green structure, the elements of functions can be connected with platforms that are integrated with stops for the water transport accommodating mosque, school, local market and public space for the communities. These platforms are the urban connectors of an enlarged public realm winding through the territory and linking the communities with one another. Raised on higher grounds, they become the small islets that lodge the urban functions and create hierarchical points in the system. CONCLUSION Since the city of Banjarmasin is confronting difficulties generated from different origins and magnitudes, solutions to this also have to deal with the diversifies factors. One thing is for sure that Banjarmasin cannot escape the tsunami of urbanization that is going to take place in the coming years. Instead of trying to stop it, the urgent stride is to be prepared for it. The city as the center for is in need of reaching outwards, not being introvert within itself. The polycentric growth caters for the possible answers to this problem of shrinking and dispersion of the inner city. Deciding on that, the next step is to agree on identifying the polycenters, find their strengths and lay out the strategies to activate them. In order to achieve this, a sound collaboration among the local and regional government, the real-estate agents and local organizations is truly desirable. With a view to reaching the common goal together, the discrepancies among different stakeholders can be overcome and worked out for.

RIVER & ROAD AS WARP & WOOF Interweaving Ecologies and Economies in the deltaic Territory, Banjarmasin, Indonesia volume 2 : design investigations. Banjarmasin had a population of 625 000 in 2010 and is moving fastly towards the one million inhabitants. The city is laced with floodprone waterways, influenced by the ebb tide of the Java Sea. At a certain moment it counted more then hundred canals, creeks and riverways. Following this contemporary pace of development, the existing city and its lowlying flood prone periphery are being overlaid with a new scale of urban fabric and programs. New infrastructures and allotments adequately canalize development but, in general, and in so the Studio aims to explore ( and simultaneously test) in strategic projects development visions for Banjarmasin that could guide its sustainable development in spatial and socioeconomic and cultural terms.
