Studio Work Water Urbism: River & Road as Warp & Woof
Introduction Asian kind can be canalized in sink with natural processes of the dynamic landscape and in relation to the legacy of the city/region. (…) A productive interplay between water structures and urban structures can once again become a fundamental identity for the city and its environs.’
Banjarmasin and Banjarbaru, South Kalimantan, feature prominently in the medium-term plan Indonesia 2014-2019 of the Indonesian government: as large cities, as priority location for a new town, as future growth center, and mainly as (the only) metropolitan area in Indonesian Borneo. It explains the prospects of a doubled population by 2030 (from 652.000 inhabitants in 2010 to 1.27 million in 2030). Simultaneously Banjarmasin is undergoing a dramatic transformation, shifting its waterbased origins towards road-based transport. Today both mentioned partners renew their focus towards ‘Advocating Urban Planning for City Leaders’, revising their guidelines towards a more integrated comprehensive planning across sectors. The focus of UN-Habitat on urban planning is framed against the very rapid and often uncontrolled urbanization, looking for more sustainable, empowering and inclusive ways to guide this expected massive urban growth or urban sprawl.The studio starts from ‘the assumption that even growth of the 14
Methodology: A strip of 25 x 80 km along the territory of Banjarbakula was chosen to frame the fieldwork. The strip spans from the Barito River, over Banjarmasin (-0,16 m), Martapura and Banjarbaru, to the Rian Kanan Dam in the mountains ( 200 m above sea level). In fist place it was collected the field work in Indonesia as part of the Water Group: Danny Osorio, Amaranta Vargas, Valentine Van den Eynde, Marion Mukolwe, Yantri Dewi, Ermawan Rekshi and Teguh Iman. In the secoun phase it was collected the studio work in Leuven as part of the Banjarbaru Group: Danny Osorio, Elena Kasselouri, Sheeba Amir and Tarek Morad. Finally the reasearch paper, was wrote based in all the field work and the studio work accomplished as part of the Water Urbanism Studio 2015. The studio starts from ‘the assumption that even growth of the Asian kind can be canalized in sink with natural processes of the dynamic landscape and in relation to the legacy of the city/region. (…) A productive interplay between water structures and urban structures can once again become a fundamental identity for the city and its environs.’

Chapter 1 Water Dynamics: Water as Structure of the Territory

Water Dynamics
Water as Structure of the Territory Banjarmasin and the greater region of Banjarbakula are part of a territory structured by water in the watershed of the Barito River system. The strip area sits on Barito River’s downstream and experiences the challenges of the delta joining the Java Sea. These are tidal fluctuations, saline intrusion and rise in water levels during the rainy season. The water hierarchy is from the Barito River starting from the central ridges of South Kalimantan, the Martapura River formed by the meeting of Riam Kanan and Riam Kiwa, the structured irrigation canals, numerous smaller secondary and tertiary rivers and storm water drainage system. The natural system has been superimposed by an artificial system which has evolved historically from traditionally built irrigation systems to Dutch canal systems and later government sanctioned canals all connected to the Martapura River. However, it cannot be considered as a purely natural or artificial system but an in between hybrid structure because there are artificial manipulation of the natural system for water intakes, normalization and canalization. Simultaneously, the artificial system has influences of the natural forces, arising from its connection to the natural water system. The irrigation canals have fish breeding naturally and colonialization by plant life in certain sections. This hybrid system can be a means of examining our modification of the water for appropriation in a city that is expected to double and the hinterland that supports it. How can we achieve an optimal relationship with the water in a conversational manner rather than defensive control strategies? How can hard engineering be integrated in a natural water system to work with the water instead of combating it? 22
Water has been discussed following three different approaches : the relation between water and land, the relationship between water and people and the relationship between water, land and time. These three dynamics that allow the appreciation the the entire water system, its challenges and capabilities. They provide a means to the identify opportunities and form a basis for strategies for development of the region of Banjarbakula.
Equalizer of Rhythms Water Uses and Appropriation
Migration of Landscape Changing Topographies
Temporal Landscape Time as Element of Landscape
In Kalimantan context, landscapes are mainly made of the outstanding character of the water body and of human uses. The main goal of this approach is to give a way to water by interweaving the rhythms of nature and humans. The point is to crate a charte putting in dialogue the different uses of water following five different environments along the strip we are studying, using photomontages. Those montages are made of several pictures showing how the uses express themselves. Those five images play with opacities to show the intensity of appropriation following the five contexts. The chart is made of two axis. The vertical one shows how intense do human uses of the water interface with natural rules and affect landscape. The horizontale axis indicates how the uses work with nature, from completely in symbiose with it to against it. The uses and appropriations are organised in nine stripes of five pictures. Those nine stripes are classified in three categories : - Social appropriations : considering water as a place to live, share and move - Economical appropriations : considering water as a space to grow, produce and trade - Technical appropriations : considering water as a space that flows, evolves and supports
The strip area and beyond demonstrate the codependent connection between the land and the water. The production, infrastructure and physical urban growth are dependent on the same system creating friction. As Banjarmasin expands, new growth is happening at its peripheries, where the land is mostly swamp. The new developments prompt excavation from hilly sites in Banjabaru and surrounding areas. The cut of the hill changes the topography to relatively flat. The fill area in Banjarmasin’s periphery shifts topographically from swamp with water storage capacity to level landfill for construction. This is the creation of new land. The mining areas, most of which have abandoned sections have resulted in gaping holes in the ground up to 20m deep. They fill up with water from natural small rivers or rainfall to form new contaminated water landscapes. This migration of landscape shifts the relationship between land and water and imposes a new kind of artificial landscape. It bears serious implications for the region. The increase of filled area reduces swamp area which affects food production area and water storage points within the watershed. It also increases impervious surface which can lead to a lower ground water table. The creation of new water areas and leveling of the hilly areas causes deforestation leading to sedimentation and creates drainage problems that pose a flood risk in the lower areas. This evolving migration of landscape will be amplified with increased growth. What kind of system can be introduced to maneuver these extreme inversions of topography arising from urban growth and livelihoods without severely breaking the water-land balance? How can the scars created on the landscape be transformed into opportunities for the expanding region?
The delta setting of the Martapura River means that the region is subjected to timebased forces that change the landscape formation hourly and by season. Time creates in-between zones where the water and land gradients are altered. The quantity of land and quantity of water are dynamic when based on time. The tidal fluctuations cause the water levels to change with high and low tide. This tidal effect creates a reverse flow that is experienced up to 39km on Martapura River from Barito River. The tidal effect meets the downward flowing river at Martapura city. The two forces create a flood zone during the rainy season. The water quantity and levels increase significantly by 1 to 3m during the rainy season. The dry season creates a contradictory landscape due to significant decrease in water levels when some smaller rivers almost dry up. The dam operates at half capacity which means reduced energy and shortage of piped clean water. Since the water pressure is lower in the dry season, saline water backflows into the river consequently causing clean water intakes to be closed. For a region immersed is water the dry season is increasingly creating a situation where there is not enough water. The water acts as a protection system during the dry season on the Gambut layer. The Gambut layer ignites during the dry season when the water level reduces and it is exposed to the sun. The rising smoke spreads into the cities and has forced the Banjabaru Airport to suspend flights due to visibility. It is a demonstration of the conflict of urban functions and water levels changing through time. How can cities plan and expand within the context of unpredictable time-based natural movement of water?
These approach allows to estimate the priorities in term of improvement. The ideal location of all the buttons is up the chart. So for example we can assume that the water used as a place to live or produce affect deeper the way water flows than using it to grow. This equalizer allows to work on dynamics that optimize the interweaving between water and people.

Chapter 111 [Eco]Logical Balance as Interface of Hybrid Urbanity in Banjarbaru, Indonesia
Abstract Banjarbaru and Banjarmasin are two cities located in South Kalimantan, Indonesia. These two cities have been developed in different ways but are closely related and the Indonesian government conceives them as the future main metropolitan area in Indonesian Borneo. The challenge of Banjarbaru and Banjarmasin as a future metropolitan area in the region is facing eventual changes linked to this process, for example, the doubling in population expected by 2030. As consequence of this increase in population these cities have to deal with the need for more productive land, the need for higher density urban development, the protection of the agricultural areas from the urban growing and the spontaneous dispersion of the urban centers. In the specific case of Banjarbaru, the city has to face the urban growth without density, a process in this moment affecting the identity and the urbanity of the city. As part of the South Asian countries urbanization process there are particular elements to take into account as the relationship between highland and low-land conditions, pros and cons of the Desakota typology, agricultural activities related to urban areas, the lack of identity and urbanity, residual spaces inside the city, the water system neglected for the urban growth and the lack of collective spaces. 42
Banjarmasin is a city where the urban growth was related to water; on the other hand Banjarbaru was developed as a plan city in the high-land areas close to the hills, where the urban growth was linked to the infrastructure. Although the juxtaposition of local and global elements is already apparent, as an intense urban expansion is in process, a shift in polarity between the two urban cores is taking place. Instead of one urban agglomeration, Banjarmasin and Banjarbaru are developing as two collaborating cities. In this sense, under the growing population and the higher ambitions of the region, the city of Banjarbaru is going through a transition, presenting an opportunity to introduce new urbanities as well as to strengthen present urbanities. An issue of up-scaling the existing urban qualities and projecting the new ones is prominent. Under this framework, several questions are raised: Which is the potential for the city to contain higher density? How to accommodate the needs of the growing population while protecting the most fertile land from an invasive urban expansion? How landscape, agriculture, urban development, water management can be articulated preserving the ecological balance of built and open space? Keywords: Urbanity, Public Space, Density, Urbanism, Dispersion, Ecology, Water.
Neglected Waterways in Banjarbaru, Indonesia 43
Introduction Banjarbaru is a city in the province of South Kalimantan, Indonesia and is located in the southeast side of Banjarmasin. The city had a population of 199,627 inhabitants in 2010 and the latest official estimate is 215,440 inhabitants. Martapura city was the last capital of the former Sultanate of Banjar and lies in the north side of Banjarbaru in a continuous urban system. The city is bisected by the major road crossing South Kalimantan; Jalan Jendral Achmad Yani road splits Banjarbaru in two sides and is connected to Banjarmasin. Water and infrastructure are the structural elements of the territory, which are forming the two main spines that guide urbanization, connecting the core of Banjarmasin to the core of Banjarbaru and Martapura City. Martapura River, as a natural spine, is shaping the productive landscape where the settlement is a linear development along the riverfront that strongly relates to the productive land. While Achmad Yani road, as the civic, spine is the carrier of an intense urbanization, concentrating in length various functions. Urban fabric as the interplay of water and road has different forms along Banjarbakula. This relation is producing a wide variety of identities; a collection of diverse urbanities is creating a mosaic of characters and interrelations. Different growth rhythms 44
and structures characterize the urbanization process. Banjarmasin has a continuous urban development that started primarily along the rivers, canals and roads filling gradually the gaps. However Banjarbaru was planned and established, as an urban center, followed afterwards by new clustered developments, forming a dispersed city. Martapura city forms a linear compact city with a strong central big mosque and market developed in parallel roads. The lack of a strong urban identity is giving space to a composition of rural and urban elements. This coexistence produces a gradient of diffuse urbanity in a changing balance. The existing and emerging centers and urbanities are consequence of the urban tensions in the area stimulated for urban catalysts as the developing port, the university, the airport and the new regional administrative center.

Banjarbaru: A City without Density “Cities of Dispersal can be recognized as an emerging type of low density environments; de-centralized, heterogeneous, radically different from traditional definitions of the city in their spatial organization and patterns of growth.� [Segal & Verbakel, 2008]. Banjarbaru city is expanding, growing and sprawling leaving its plan city center shrinking. The city is waiting for a reorganization process of the built environment where a redistribution of the densities of buildings, population and activities needs to take place. Probably one of the effects of the westernization process is the emulation of dispersed and diffused urban process from American or European contexts; in this regard it is being taken of a global tendency in the urban development of emerging countries, especially in Asia. In this kind of process the public space is a determined element in the understanding of the new urban context of the city and how is its role in this new dispersed environment. In the case of Banjarbaru there is not a hierarchical organization of densities, therefore it is impossible to read the distinction between urban and non-urban context. The city started to grow from the plan center to less dense areas without order and structure creating a lack of identity in the country side and a lack of urbanity which can 46
The Process
47
be considered as possible dense areas close to the city center. The problem of blurred distinction between city and countryside is originated in the loss of the traditional city boundaries, for this reason is imperative the redistribution of urban activities and intensities where it can be recognized a clear pattern of high density in the city. On the other hand, the sprawled low density environments in Banjarbaru, probably more than half of the city, it is not recognized as urban nor as city due the lack of density, the absence of a coherent urban fabric and, a non-existent relationship between pedestrians and urban space related to the lack of forms and uses of urban public spaces. In this regard, the attempts to qualify the dispersed city of Banjarbaru refer to the
48
loss of coherence, definition and limits in the different urbanities; however the strategies for these issues emerge from these losses where the dispersal can be an opportunity to reinvent urbanity. Public space plays a crucial role in the [re] definition of the alternative urbanities in the sprawled conditions where it can act as a place of exchange, inter-connectivity, overlapping of networks and as an attractor of diverse programs creating an intensity of identities which generate urban coherence and the active use at different scales. The new interventions in the public space should protect the existing urban configuration of the city as a catalyst of the collective dimensions of the dispersed urban condition of Banjarbaru. As a city in the South Asia context, it is the place
for new forms of collective space integrated to the rapid process of urban expansion where the fragmentation of the city can be used as a base for a new urban structure that allows the landscape to interplay with the urban fabric, using the residual spaces as means of transformation of the city based in new possible attractors. The envisioned future urbanization in Banjarbaru proposes public space as a strategy for the new urbanized areas and for the former active city center. In general, the [re]densification process combined with agriculture, ecological tourism and other forms of landscaping, as a method guides the urban growth and the renewal of the dispersed urban conditions. Green, blue and collective spaces can revitalize and intensify
the urban experience in the city, reinterpreting the “urban emptiness�, knitting together the complex urban programs attached to the infrastructure systems, generating multiuse spaces and changing the way of use, appropriate and inhabit the collective spaces as part of the public realm. Residual spaces, voids and fragments can become an ecological system where landscape, water and collective spaces take the prominent role as emergent types of public space stimulating the densification process around them and acting as an interface between the existing conditions and the [re]interpretation of the nature as public and collective space in Banjarbaru.

Desakota “First, desakota regions are so vast and difficult to navigate that they produce administrative “blind spots” in which planning regulations are not enforceable in any uniform way. Second, desakota regions feature a high mobility of goods and services and a transient pattern of settlement. Third, and closely related, desakota regions resist being takenup into a more formal system of interconnected functionally specialized zones.” [Cairns, 2002].
In the South Asian cities desakota is a not conventional mode of urbanization which mixes the identity of a town and a village in a spatially fragmented densely peripheral settlement pattern as a suburban development close to a major urban center but always linked to the agricultural areas. In the South Kalimantan context we can find, according a McGee´s desakota categories, the desakota type 3, characterized by a high population growth and a slow economic growth in human settlements close to the urban centers, in this case Barjarbaru and Banjarmasin. In some cases the desakota areas were absorbed for the urban growth of these two main urban centers, creating “desakota islands” in the middle of urban areas but totally disconnected of the surrounding city, without infrastructure, services or public space. Desakota as an urbanization process has deep economic issues and poverty problems, however, this typology is a good case study of synergy between urban and rural, the consumptive and the productive landscapes as a possible new hybrid urbanity capable to improve and articulate as part of the city and as a possible device of interchange between urban or rural areas. 50

Agriculture, Urban Agriculture, Productive and Protective L andscapes “The continual interaction of human settlements with productive landscapes for necessity and survival has evolved over the millennia into complex systems of balance. The interrelation of networks of infrastructure, landscape and settlement supports different habitats and social landscapes across the territories.” [Shannon, 2004]. Agriculture, Urban Agriculture, Productive and Protective Landscapes “The continual interaction of human settlements with productive landscapes for necessity and survival has evolved over the millennia into complex systems of balance. The interrelation of networks of infrastructure, landscape and settlement supports different habitats and social landscapes across the territories.” [Shannon, 2004]. In South Kalimantan region the agriculture is one of the most important activities, a large percentage of the land is dedicated to agriculture. The cultivated land is part of the domestication of the nature by the human being but it is still part of the ecosystem. In this regard, in the Banjarbaru north-west side there is an important concentration of “dry agricultural activities” in the high-lands close to the airport of the city. The productive landscape in Banjarbaru is part of the large ecosystem especially related to water. The drainage system of the city is an important hybrid structure that serves as a functional infrastructure element inside the urban fabric and outside of the city it becomes part of the irrigation system 58

in an ecological balance between natural and artificial, and urban and rural. In this case, the rapid urban growth is consuming the productive land threatening the cultural identity of the agricultural areas. An important point in the strategy related to these issues is the effort for protecting the agricultural landscapes. However, agriculture can be part of the city considering it as an urban model and as an emerging hybrid identity between agricultural and urban, where there is a juxtaposition of agriculture and urbanity. In spite of the fact that the urban agricultural activities are an important part of the ecological balance of the natural spaces inside the city, it becomes a relevant alternative to social and economic issues for the low income population. The protection of the productive landscape is a valuable alternative for food security, additional income for lower income households and a source in the supply of urban food, which is an important issue in the sustainability of the cities. As a climate change strategy, it contributes in the creation of microclimates and it is an important opportunity to re-use urban organic waste and the possibility to integrate them in the process of waste-water purification. The agricultural urbanity in Banjarbaru is an emerging structure with potential to be part of the urban system of the city.

Reclaiming Waterways: Renewed interpretation of the Collective Space in Banjarbaru “In several projects that Turnescape has been involved with in the past years, a central concept has been to bring the city and citizens back to the water, whether it is for new town development or urban regeneration.� [De Meulder & Shannon, 2013]. The hydrological system in the region is composed by the Kanan Dam in the Meratus Mountains in the east side of Banjarbaru, Riam Kanan and Riam Kiwa Rivers originate Martapura River which is tributary of the main river in the region, Barito River. Banjarbaru is located in a soft-slope hill at the foot of the mountains and for this reason it is part of a network of small rivers flowing naturally from the top of the hill through the city to the lowlands, becoming part of the artificial irrigation system and even disappearing in the lowest parts of the wet-lands. These small rivers inside the city have been neglected in the backside of the urban tissue as part of private backyards or residual useless spaces. In fact, these waterways play an important role as a part of the drainage system of the city. A strategy to recover these potential spaces is reclaiming the green-blue lines as public space for structuring the urban fabric restoring the rivers, protecting the river sources inside the city and revalorizing
Green Bouleverds uograding the Airport _ City 61
the rivers as a potential element of the ecological system. As well, this can be considered as a functional structure of the city that reduces the cost of underground drainage pipes while preserving the ecological balance in the urban context. “Ecological infrastructure, a structuring landscape network, is a means of safeguarding the integrity and identity of the natural and cultural landscape and in securing sustainable ecosystem services. Ecological infrastructure focuses on three landscape categories: abiotic processes (mainly water management), biotic processes (native species/biodiversity conservation) and cultural (heritage protection and re-creation) and has works in tandem with landscape “security patterns” as a powerful tool for open public space conservation […]” [De Meulder & Shannon, 2013]. Regarding the future double population of Banjarbaru and the rapid urban growth, the critical spatial strategy is an alternative solution based on landscape, natural processes and the existing hydrological conditions of the site. The new structure of the city is based on blue (water) and green (landscape) as a new form of collective space with natural water retaining capacity, an interconnected network of waterways and wetlands, protected at the same time for the public space and ecologically recovered. The protection of the low-land as a permeable land is an essential element of the new green-blue public space system across the city. The landscape is used as an articulator of natural and collective processes to frame the city and provide diverse ecosystem services. These will be used for residents to integrate and connect the natural, biological and cultural processes to the ecological, cultural and recreational services as the structure of the urban form and to stimulate new developments of real state around itself. 62

New Urbanity _ New Identity: Banjarbaru 65
Conclusion The rise of the new metropolitan region in Indonesian Borneo must be developed on the foothills, where the city of Banjarbaru is located in high-lands on good soil conditions, on a hilly island surrounded by wetlands, which is an important part of the Indonesian identity. The city has the capacity and the potential to accommodate the coming double population and is capable to face a rapid shift in scale and density of the new urban developments. Nowadays, the lack of structure of the dispersed development is resulting in a lack of identity and a fragmented urban development process is expanding, lacking of connectivity, order and structure. The emerging patchwork is producing a fragmented and dispersed urbanity that shows no concern for the ecological elements present inside the city. The existing green-blue lines inside the city of Banjarbaru are currently part of this fragmented dispersion, suppressed from the expanding urban development. The potential of this natural structure is crucial for the existing and the emerging city, because it is capable to constitute the new public spaces system and stimulates a more dense structure. The ecological network of landscape and water is at the 66
same time part of the drainage system of the city, connected with the waterscape. The main guideline for these water courses is the topography of the area that creates a complex interplay of ridges and valleys which is imprinted in the contemporary city. At the present time, the urban expansion of Banjarbaru city is related to the highland and low-land, the new urbanization areas in the region are primarily occupying the high-land as the suitable space for urban development. In the frame of a more dense and compact city, associated to public space and infrastructure, the [re] interpretation of the inner and outer edge between city and green areas is essential as a strategy. This strategy is meant to guide the spontaneous infill and the colonization process of the landscape, protecting the hydrological system, the green structure and leading the future urbanization process in congruence with the natural processes. The collective space as a [re]interpretation of the public space is the new structure for the emerging city; a network of public parks acts as an inner urban-rural interface and as a part of an ecological system that contributes to the natural water purification
process and low-land reservoirs for water. Upgrading the existing urban tissue with new mixed typologies, integrating housing and agriculture, integrating high density with open spaces and natural dynamics, the strategy to connect the landscape through the city addresses the issue of the fragmented dispersion while protecting the agricultural landscapes.
structure of the fragmented and dispersed city, preparing Banjarbaru for be the new metropolitan region in Indonesia.
This ecological system of collective spaces in the city is the urban structure that strengthens the three different urbanities in the city, providing at the same time guidelines to lead the urban growth in different ways: the agro-city, the airportcity and the administrative-city. The green-blue ecological system integrates urban agro-pockets with a series of green boulevards and a network of linear transversal parks. The green-blue lines are interconnecting elements of multiple urban scales while stimulating high density around. The densification process through the new ecological system of collective space is a strategy to strengthen the sense of urbanity in the context of each identity. The public space that concentrates collective services is a device for directing the future urbanization process in the city in an [eco]logical balance and as the 67
