RE-IMAGING SUNGEI PANDAN LANDSCAPE

Landscape architectural approaches to revitalize coastal habitats in a high-dense tropical city

LOSS OF COASTAL HABITAT OF SINGAPORE

Situated in the tropics, one-and-a-half degrees north of the equator, Singapore is an island nation located in one of the most species-rich regions in the world. The land was originally covered by primary rainforests, mangroves and freshwater forests, harbouring thousands of floral and faunal species in a complex tropical ecosystem (H. T. Tan, Chou, Yeo, & Ng, 2007). In the mangrove forest alone, 56 of 70 of the world’s mangrove species could be found in Singapore, the most numerous in Southeast Asia (Yang, Lim, Sheue, & Yong, 2011). However, the clearing of land for settlements, starting from the late 1800s and continuing into post-war urbanization in the 1960s, have resulted in widespread deforestation, leaving less than 5% of the original habitats intact (Ng, Corlett, & Tan, 2011). Over the years, these local habitats are projected to further decreased and deteriorated as they become increasingly fragmented due to urban growth (Brook, Sodhi, & Ng, 2003; Corlett, 1992). Almost all of Singapore’s shorelines have been drastically modified to meet industrial, residential, water resource and recreational demands. Most of the natural sandy shores and river mouths on intertidal shores have been reclaimed, losing 65% of original coral reefs and decreasing mangrove forests coverage from 13% of the total land area in the 1820’s to 0.5% in 2011 (Yee, Ang, Teo, Liew, & Tan, 2010). These massive changes and fragmentation of the coastal ecosystem disrupts aquatic ecosystem processes, and decreases water quality (Friess, 2016a). According to the 2008 Master Plan and 2011 Concept Plan, however land development in Singapore continues unabated and planned land reclamation will result in additional losses of 33% of the existing mangrove area. It is apparent that many of eth natural coastal habitat face to shrinking area, increasing fragmentation, and encroaching by urban expansions (Lai, Loke, Hilton, Bouma, & Todd, 2015). This occurs in the context of climate change, which brings about mounting environmental pressures such as sea level rise, altered hydrological regimes and sediment supply (Burkett, 2012).

However, this does not mean that all coastal habitats are dead or we should stop the land development. As calls for conservation are often seen as impractical in the economically-driven state, alternative landscape architectural approaches are needed to address the social and ecological consequences of rapid development. It is unhelpful to see economic development and environmental conservation in a zero-sum game, where a clear winner or loser emerges in any contestation over a land lot slated for development. Instead, we look to find means of reconciling these objectives that are currently framed in opposition to each other and develop design strategies that could address both economic and environmental concerns.

SUNGEI PANDAN

While existing mangrove forests are mainly located along the northern coast, originally the southwest shore had the largest mangrove forested areas in the main land of Singapore. Sungei Pandan is a remnant mangrove forest located along the stretch of Pandan river. It lies between the Pandan Tidal Gates and the Sungei Pandan Bridge. Of the original 219 hectare mangrove forest, only 9ha remain, in the form of an isolated strip within the industrial business zone in the Jurong district. The river has been dammed to form the Pandan reservoir with conventional engineering treatments that disrupts flow and separates the stream into two parts with distinct characteristics. The upper reaches of the river has been canalised with cemented banks and beds – it runs to the PIE and branches out to Sungei Ulu pandan at AYE. Across the PIE, with a continuation of Ulu Pandan Park Connector to Bukit Batok Nature Park, Sungei Pandan provides opportunities for nature walks and birdwatching. The lower part of the river still opens out to the sea, remains relatively natural ecosystem with stands of various mangroves including rare Apiapi Jambu, and became a home of avian residents of the watery forest and other mangrove fauna species. Besides a rich diversity of flora and fauna, the Sungei Pandan provided livelihood opportunities for a village of 135 human inhabitants many of whom was fishermen or prawn farmers before the area has been cleared in 1960’s. Sporadic informal fishing and bird watchers can still be spotted along the riverside, offering a vestige of the old kampong life that once thrived in the area.

Although this remnant of mangrove forest has been designated as a ‘protected’ park space by URA plan 2014, the coastal habitats in Sungei Pandan has a high risk of extinction due to the relatively small size of the mangrove forest and development pressures by highly urbanized neighboring contexts. The forest lined much of the canalized banks of the Pandan and Jurong rivers being surrounded by factories (Jurong industrial zone), heavily used ports (Jurong port), and managed park land styled urban greenery (West Coast park). Like recent port development cases of Singapore, it has also a strong possibility to transform the port land into mixed urban development in the nearer future as similar as other cases of coastal redevelopment (Wong, 2006).

The Sungei Pandan was selected as a ‘landing’ site and serves as a point of reference for all design activities – sites selected were inspired by findings from the coastal landscape and its surrounding context. Students chose his/her own design boundary along Sungei Pandan or in its immediate periphery, based on problem statements and topics arising during the research period, aided by the various design exercises and input sessions.

RE-IMAGING SUNGEI PANDAN LANDSCAPE

How can we effectively conserve the existing coastal habitats while meeting the increasing human development demands? Given the future development requirement and sea level rise, how could initial infrastructure planning be guided towards a sustainable coastal ecosystem and the diversity of wildlife? Beyond simply preserving the site, can landscape

landscape architects propose design prototypes that can infuse greater ecological functions and diversity into the urban coastal context? How can design promote a healthier lifestyle that closer to nature for city dwellers? The studio aimed to answer these questions by devising new strategies and design applications of ecological principles, predicated on deep awareness of the multi-faceted nature of our city landscape and the intricate feedbacks between social and ecological factors in the city.

The studio highlighted the value of natural resources and ecological services, and propose ways to integrate them into our urban environments. We capitalized on the academic nature of the studio to develop ideas and schemes free of restrictions commonly faced in the practice, and beyond any constraints of political correctness. Multiple issues such as identity, multi-functionality, and livability have been examined.

THIS BOOK is a compilation of works from the studio. The first half of the book documents the sequential studio process from the beginning of preliminary research, site analysis and prototyping. The fourteen-week logbook is a useful demonstration of how initial activities and resources can be transformed into viable design proposals. The studio started off with site analysis as group work, giving rise to backgrounds of and motivation for subsequent design topics. Four approaches are emphasized from the studio: 1) developing a strong awareness of site specificity; 2) deepening our understanding of urban ecology; 3) producing a wide ranging spectrum across scales; and 4) encompassing various functional layers. Lastly, the reflections address all that we have come away with from every single experience we had during the entire studio process.

HISTORY OF JURONG DISTRICT

The Sungei Pandan mangroves, found along the stretch of river that lies between the Pandan Tidal Gates and the Sungei Pandan Bridge, is perhaps the last remnants of the lush mangrove forest that had once lined much of the banks of the Pandan and Jurong Rivers that had been offered protection as the Pandan Forest Reserve.

Before 1961, Jurong was a tangle of mangrove swamps, jungle, farms and small kampongs. Like many other parts of Singapore at that time, it was still a vast wilderness of jungle and wasteland with no metalled roads.

THE SYMBIOSIS OF COASTAL LANDSCAPE SUCCESSION IN A HIGH DENSE NEIGHBOURHOOD

Sungei Pandan, a 2.8km river with fragments of mangrove fringes – one of the highest mangrove richness in Singapore – is surrounded by industrial factories that pose high environmental disturbance, limiting ecological linkage between Sungei Pandan Mangroves and West Coast Park. Demarcated as a future private high-dense residential waterfront development placing the current industrial site, the phases of construction, new land-use implementation and proposed programs are three significant factors that will greatly affect the conditions of the major green cores. Unconventional development with highly manicured urban greenery often swiftly constructed results in fragmentation of habitats and biodiversity loss due to poor development strategy to integrate existing habitats and drastic timescale difference which disallowing nature to “grow” with human intervention.

Ecociety Living, located at the waterfront and West Coast Park’s Marsh Garden serves as an alternative prototype for coastal ecological development to achieve a symbiotic relationship of coastal succession within a high-dense residential neighbourhood.

The design construction for both human intervention and provided ecological zones with planting strategies that multiplies social and ecological values are developed in phases to allow adaptation of existing ecology and accelerates ecological succession within the urban environment. Learning from the existing natural habitat in Sungei Pandan, constructing of new waterways and naturalising existing canals are strategies to tackle flooding concerns while introducing riparian conditions inland which integrates aquatic stratification to existing landscape densifying its ecological functionality. The project incorporates necessary environmental parameters which blend untamed vegetation with the naturalised urban landscape to strengthen biodiversity connectivity and provide ecological patches within every precinct. To create a biophilic experience for residents, communal programs, facilities and building design are oriented to maximise human and nature interaction, increasing residents to knowledge and appreciation in living within proximity with wildlife.

Ecociety Living aims to redefine future approaches in coastal development to rehabilitate coastal habitats within the urban environment and eradicate bio-phobic misconceptions while ensuring continual development growth.

GROWING TOGETHER: SEEDING COASTAL HABITAT INTO HIGH DENSE DEVELOPMENT AREA

Mangroves, the forgotten fortune, are disappearing rapidly as the urban jungle encroaches on its existence and threatens its survival. The narrow slice of Pandan mangroves lies at the edge of Jalan Buroh Bridge, which has insufficient space to develop strong biodiversity and resilience due to the coexisting pressure from urban sprawl. Growing together tries to find a new relationship between coastal habitat and urban area under the new development. This project selects the highly critical area, which is near the bridge and located in the Southern bank of Panda River, as the first area for intervention.

On one hand, this project attempts to expand Sungei Pandan mangrove to strengthen it, enabling it to become a key refuge for the ecosystem. The first step is to create a suitable environment for new coastal habitat by preparing the soil, topology, and hydrology. Through creating unique landform, topology and flexible growing space, the new habitat will get a safe and stable environment to flourish. At the same time, with the strategic planting scheme, the site provides a unique habitat for back mangrove conservation while utilising urban infrastructure as a new habitat to connect current mangrove habitat and the seeding habitat.

On the other hand, this project tries to integrate ‘seed habitats’ - ecological succession patches - with high dense residential to ease the adaptation with urban intervention. Unique terrain is created as a transition zone to reduce the impact of urban for coastal habitat by using the 2.5 meters height difference from inland to tidal zone. Meanwhile, physical and intangible connections are created between seeding habitat and residential area by integrating human activities and coastal habitat with mixed land use, connecting inland drainage system, sea and designing plants for fauna flow.

In 25-30 years, the first ‘seed’ will grow up with a stable system where following coastal habitat successions will grow similarly like the first succession along with the urban developing. Finally, the strong ecosystem of Sungei Pandan will be established.

COASTAL LANDSCAPE AS STORMWATER MANAGEMENT INFRASTRUCTURE

Over flooding of stormwater runoff is a common issue in highly developed urban areas where impervious surface treatment and hard engineering infrastructure for stormwater management often conflict with natural water flow. The project serves as a green-blue plan for the future residential area along the Pandan River to reorganize the problems regarding the water flow in high-dense urban context and mimicking the natural capacity of flood conveyance and storage of the land with three proposed strategies.

First, the design attempts to decentralizing stormwater management by diversifying water catchment areas based on natural water flows. Traditionally, as rainwater is unable to be absorbed by previous mediums, it will then become surface runoff which will be received by conventional drainage system on site, canalized to the main canal and finally get discharged into the sea. However, by discharging the surface runoff directly limits its potential for ecosystem services. A more ecological way is to retain the water on site and follow the natural water process which reduces the volume of surface runoff and its discharge rate, facilitating its infiltration. In this case, the design fully respects the natural landform and decentralized the catchments by following the nature catchment boundary.

Additionally, optimizing in the capacity of stormwater management by using strategic designs of the green-blue network directs water to water-centric zones. Different from conventional treatments which hide water channels, this project inserts green spaces combined with ABC water features to receive the surface run-off from buildings and pathways to form a greenblue network which is visible where people can appreciate.

Lastly, the project provides more habitat areas for coastal biodiversity through thoughtful plant selection. For a unique coastal land, the existing pump station of Pandan river separates the merged water conditions into freshwater and seawater which generates both constraints and opportunities for my design. With the unique mangroves growing on the tidal mudflat, these factors can potentially provide various species habitat which the project identifies to create additional buffer zones to mitigate the extreme flooding and provide more coastal habitat.

The project envisions Sungei Pandan to be an ecological and multifunctional urban community where the water feature could be integrated into the coastal infrastructure to effectively manage stormwater runoff.

THOUGHTFUL PLACEMENT OF GREEN SPACE FOR RESILIENT LANDSCAPE

Under the influence of global warming, sea level rise and abnormal climate threaten the coastal areas all over the world. Sea level rise causes a series of impacts on coastal habitats, species, and ecosystems. Heavy rainfall caused by abnormal climate has triggered intensive floods storm that affects the life of coastal residents.

Our site is located on the southern coast, and the previous industrial zone has 68.5% impervious surface the existing green space which covers only 18.3% of the site. According to the planning scenarios, our site will become a new residential area in the future. The rapid-growing population brings opportunities and challenges of the site development. My design starts from the green space, through reserving significant space for natural habitat and transforming the grey spaces to create additional functional green spaces. The design establishes a variety of ecological resilient, water resilient and social resilient landscape to cope with the changing climate and hydrology conditions with the rapidly growing population.

According to different site conditions and users’ needs, I use different design control to thoughtful place five kinds of green spaces. Firstly, biotic research, conservation areas, wildlife preservation and observation area are integrated to provide eco-resilient green space to supply sufficient riparian zones for existing species and potential species which increases the mangrove habitats from 9ha to 12ha.

Secondly, roadside green areas and buffer zone areas are mainly used for creating water-resilient green space to defence against the effects of sea level rise and intensive flood storm. Thirdly, recreation areas & urban development areas are used to establish activity spaces for people.

By thoughtfully placing the green spaces, the site will become more resilient to cope with issues regarding rising of sea level and abnormality of climate conditions. Also, under the impact of high population density, the site can provide more open spaces for people to have an intimate connection with nature.

RECONNECTING THE INTERACTION BETWEEN THE WILDLIFE AND HUMAN ALONG THE COASTAL LANDSCAPE

In a high-dense development, the strive for a balance between the living space for human and wildlife is always a challenge. Sungei Pandan has lost a large area of vegetation throughout the years due to industrialisation. The development of industrialisation has progressively destroyed the vegetation at a rate where the natural habitats could no longer replenish itself and be self-sufficient.

As there are already a substantial number of species had already been recorded to have shifted from their usual breeding grounds along the coastal landscape as well as migratory birds who have the potential to perch in Singapore in their migratory route. The design adopts two main strategies to create habitats ideal for the avifauna which encourages migratory birds to perch in Singapore and prospers the local birds’ population. Furthermore, by increasing mangrove swamps as the primary habitat, it also attracts aquafauna to inhabit and serve as the main food source for the migratory birds.

The first strategy is to restore nature element in the urban condition, such as naturalising of river canal to create riparian buffer zones which improve biodiversity and encourage avifauna to reside. The planting edge provides a green buffer for the aquatic habitat and aids in the removal of contaminants from canal water and stormwater runoff which also serves as a living filter for urban space. Furthermore, the project redirects migratory birds that pass Singapore when traveling to neighbouring countries to stopover at our coastal landscape. An opportunity of increasing species richness to the mangrove region by imprinting ideal living conditions which they can strive such as mimicking vegetation of their homeland.

The secondary strategy is to redefine boundary between human and nature. This method includes promoting nature appreciation by bringing people to be involved and interact with the avifauna through ecological activities. This creates ecologically friendly habitats in the managed built environment such as rooftop garden on residential building for avifauna to stay.

In conclusion, the project constructs ideal living conditions for the migratory birds at Sungei Pandan which creates new sightings for the locals and tourists that increases its economic value and improves the ecosystem of both wildlife and human to established in an urban environment.

IMROVING AQUATIC HABITAT

As a result of urban development, the coastal habitat is fragmented and isolated which disrupts aquatic ecosystem process and decrease water quality. This project aims to create a new aquatic habitat to improve existing conditions. I choose the certain species – seabass as the project’s starting point -

As there is an abundance of them living here in marsh lagoon behind mangrove areas, serving as a protection for mangrove roots. But now the number of seabass is decreasing drastically. This project is located in a part of the industrial zone in Sungei Pandan area next to drains where fishes inhabit. This area has potential to be connected to the remaining mangrove zone that allows fauna to move through.

The first strategy of this project is to imitate aquatic habitat working process by providing different habitats for different growth stages of seabass that serves as food and shelter for aquatic animals. By creating a spawning area which satisfies the condition for seabass to grow with shallow water with low flowing speed and fine-grained substrate, this will allow related plant species to flourish.

The second strategy is to create fish nursery area, by planting new mangrove as shelter and food source for the juvenile fish. The design slows down the water speed by changing the water topography, planting of new mangroves and removing a part of the industrial area to let water in.

The last strategy of this project is to improve the connection between nature and urban environment by adding educational area and building a long path that extends into the mangrove for people to see the whole aquatic ecosystem process.

With the creation of new aquatic habitat, not only strengthen the ecological function, but also enhance the connection of the existing habitat, this provides a new habitat for seabass to regenerate that positively improves the conditions of all related coastal species.

MORPHING FAUNA BARIER IN COASTAL AND URBAN LANDSCAPE

With the rapid growth of urban environment, spaces pose a challenge in this dense metropolis. Urbanization had undeniably caused landscape fragmentation, which in turn causes habitat isolation. This impedes movement of local fauna, as the harsh dense environment provides no room for them to live in. Further habitat isolation will cause great negative impact for our urban wildlife over time such as decreasing species population. So how does the City in a Garden resonate in an industrial landscape? This project focuses on morphing the barrier in the urban and coastal landscape, using the existing local habitat, as well as infrastructures, as part of its formula.

Landscape connectivity is the key factor for maintaining species diversity in a fragmented landscape.

The limited variety of habitats for animals isolated from one another due to developments and insufficient existing landscape where these animals rely on for movements are identified key issues this project strives to tackle.

The first strategy is to provide habitats in the dense urban areas. To achieve this, firstly, a continuous tree canopy will be maintained throughout the site to serve as stepping- stones for these fauna. Secondly, by mimicking the forest structure in suitable spaces to provide a more diversified habitat. Thirdly, strategic planting designs to accommodate the needs of different species. The second strategy is to integrate habitats in the built environment. This includes retrofitting of building structure and enhancing streetscapes to connect with nearby habitat.

“Morphing fauna barriers” is meant to provide a vision for initiating a solution to the imperative tension between biodiversity and urbanization. Through the implemented strategies and tactics, the overall site will have optimum ecologically viable spaces whilst achieving heterogeneity of species in the Southern part of Singapore. With an increase in habitat, heterogeneity leads to increase in species diversity, expanding Singapore’s biodiversity in our shared landscape.

RETROFITTING INDUSTRIAL LANDSCAPE INTO EVERYDAY LIVES

The perception of mangroves disservices was dominant in research reports. The way people perceive mangroves were mainly negative, treating them as a reservoir of disease, areas of danger and harbour of pests. The public only sees the alluring conditions of the coastal landscape but have not understood the important aspects of mangroves ecosystem services which are beneficial to our biodiversity and environment. Migrant workers being dominant in the industrial district allows the project to focus on their culture, stories, lifestyle to reform spaces which serves to educate and raise awareness of the importance of what coastal landscape while allowing them to enjoy implemented recreational activities.

No.7 Pandan Road, currently an abandoned site is specifically selected for a variety of reasons, in terms of Nature & Human considerations through precise studies, observations & research of biodiversity, habitats especially mudflats and proximity of green spaces.

By adopting the Biophilia methodology, bridging social groups with green spaces and injecting activities helps to cultivate stronger and closer affiliations between humans and nature. Thus, elevating migrant workers working attitude, efficiency and efficacy which could be beneficial in their working prospect and the economy of the country

Redefining the coastal landscape where it allows a larger volume of sediments to be deposited, creating a larger area of mudflat, boosting feeding grounds and habitat for fauna and infauna species. Introducing patches of green spaces in the site and enhancing the existing slipway with recycled materials on site draw users closer to the coast physically and visually.

Retrofitting the longitudinal streetscape of Pandan Road, by mimicking the structure of the coastal forest, creates a green canopy framework that elevates fauna and flora habitats and their movement which will be beneficial for the biodiversity and ecology. With this implementation it helps to increase vegetation volume and create larger shaded area for workers commuting along Pandan Road.

These strategy aims to foster a greater appreciation of nature within a particular target audience and cultivate a stronger sense of ownership to the created landscape and at the same time boosting ecological and biodiversity value of the area which could leave a positive impact in the industrial environment and hopefully to the future generations.

MITIGATING MICROCLIMATE IN THE INDUSTRIAL AREA

With the increasing world population and urbanization, the need for reducing urban temperature and their related health consequences is becoming more critical. The design of pandan road aims to investigate the magnitude and the potential of street space cooling to mitigate the heat caused by urban heat island effect. It is an attempt to reduce the impact of industrialisation on the surrounding environment for the future climate change.

The temperature in the site is relatively higher than its surroundings and the cause of the phenomenon is due to high hardscape percentage and reliance in drainage conventions to allow efficient discharge of surface runoff. The wall between the street and factory area creates a barrier that makes the streetscape fragmentized where there is inadequate space for tree planting to provide more shade to cool the area. In addition to the heat and barrier, the design of connecting public space is also required to be addressed.

Three strategies are used in creating a design solution and a plan for the site, the project aims to mitigate specific development impacts and compensate lost ecological functions.

Firstly, by integrating the fragmentized green space and removing of existing barrier between the street and factory. The design will implement movable landscapes, private planting spaces and private car parking spaces to create a more continuous green space within the urban environment. Secondly, based on the topography and the precipitation, the design of bioswale is applied to slow down the rainwater while providing evaporation from plants to cool the area.

Lastly, the simplex structure of trees in the site is redesigned to provide more shade for the thermal comfort of people while enriching the biodiversity of the site, cooling the place for workers to commute and rest outdoors.

With these interventions, the design fully utilises the potential space in the street and change the existing impermeable area into a more resilient green space.

Based on the existing topography and soil condition, the design strategy is to utilize stormwater management to cool the area and increase the habitat condition of the area. Through the design of bioretention swale, rain garden for infiltration, lawn for purification and activities through these areas. The design of storm water system based on the process of rain water stream can effectively cool the area because the evaporation of the water and vegetaion can cool down the temperature. Meanwhile, the areas are designed combined with urban trees planted in consideration of the breeze wind.

NEW INDUSTRIAL LANDSCAPE AS A LIVING MACHINE

In Singapore, the 42% of coastline, which is occupied by the industrial area, is covered with man-made vertical seawall. In Sungei Pandan’s industrial area, there are lots of factories, including many seriously polluted shipyards. The contaminants flows into the sea with rainwater, causing a negative impact on the natural environment. The pollution analysis indicates that the factories along the Pandan River, which are shipyards and manufacturing industry, have the most serious pollution level. The project aims to propose a new prototype of industrial landscape that is beneficial for improving the ecological and environmental quality through biological purification system while serving recreational activities for the public.

Four strategies are used during the design process. Firstly, ensuring the space for water treatment plant by replacing the current factories in the site; secondly, establishing of water treatment process based on the principles of wetland ecology to purify the water sequentially from sedimentation pond to heavy metal treatment then pathogen treatment and nutrient treatment. The treated water will be used for plant nursery before flowing into the sea. Thirdly, increasing of public engagement by combining the water treatment process with education, enriching people’s space experience; fourthly, creating aquatic habitats by modifying the coastline and creating an inter-tidal zone for mangroves and other plants and animals.

The project envisions this new kind of prototype of the industrial landscape will be duplicated along the entire coastal industrial zone in a long-term plan to create an ecological coastline for purification, restoration and education.

NATURING URBAN: RESOLVE THE TENSION BETWEEN URBAN AND NATURE HABITATS, LEVERAGING ON NATIVE HABITAT STRUCTURES IN SUNGEI PANDAN

In the highly industrialized area of Sungei Pandan, there are two narrow patches of mangrove/ coastal forest habitat remnants, one at the upper stream of Sungei Pandan river is preserved from the original Pandan Forest Reserve, the other is the rejuvenated mangrove at West Coast Park. However, their conditions are compromised by the urbanized context, with constrained space for establishment and disconnected from external ecological connections. To tackle the increasingly intensive relationships between urban and nature, the existing ecosystem of Marsh Garden and the neighbouring concretized canal - Sungei Pandan Kechil - and adjoined urban park space of West Coast Park are chosen for intervention. The design intention is to dissolve and transform the edges between urban and nature, modify barriers and thresholds hindering human-nature interactions, ultimately creating new urban-nature relationships and reforming the interconnection between nature ecosystem and human social system.

Existing urban attributes (landform, drain line, edges) would be utilized through feasible treatments to create conditions for nature to thrive. Leveraging on the established habitat structure of Marsh Garden, more diversified habitats are planned to be developed in phases. Toning between these different habitats is strategized for amplifying nature process and improving the resilience of the ecosystem, meanwhile enabling nature to be woven into urban fabrics.

The thriving ecosystem also function as sustainable landscape infrastructure. Multi-layered and multi-functional spaces serving as transitions between urban and nature improve people’s access and spontaneous interaction with nature. Dynamic programmes are integrated to cater to the needs of surrounding community (particularly urban workers, residents, schools, research institutes, etc.) and further create opportunities for social practice of ecosystem service value articulation. The narratives of new human-nature relationship are conveyed through design, for reshaping regional human ecosystem and morphing new sense of place and sense of nature. Retrofitted into vibrant space for coastal habitat research, learning and recreation where a new identity for West Coast Park is to be derived.

This project is envisioned to realize wider regional impacts through reviving of nature, both ecologically and socially. The co-existence and mutual benefit between urban and nature is to be addressed in a broader sense.

AN INTEGRATED WATERFRONT BASED ON BROWN EARTHWORK

Singapore is facing the impacts of high-density urban development. One of these impacts is the contamination of residues in urban brownfields. Being an important node of Sungei Pandan, Pandan river mouth’s waterfront is a nexus of river-based industry, transportation, commerce and maritime activity at the current stage. The site is located in Pandan waterfront industrial area, which is working as a shipyard with a high level of soil contamination, a mixture of organic and inorganic contaminants. Thus, this project seeks a comprehensive way to restore the waterfront area by pollution treatment process and reshape the relationship between ecology and urban system.

The surface runoff in current situation brings contaminants from factories, urban traffic and residential areas to the waterfront area where there is no hardscape to prevent the bare ground from being polluted by these contaminants. The contaminants in the soil are hard to be filtered or degraded with a very low level of vegetation density in the site. While treating the polluted soil, we need to dig out the hot spot and cap the polluted soil. It is a chance to generate a new landform by fully utilizing the brown earthwork.

There are three main strategies in this project, namely, mitigating soil pollution, utilizing nature succession, providing potential for habitats and social programs. The strategy of mitigating soil pollution happens on the whole site with the application of two tactics for this strategy: cutting and filling brown earthwork and using phyto-techniques. On the cut shoreline, the strategy utilizing nature succession is aiming to generate a new shoreline by sediment baffles, which will be set in the water edge and cutting out area for the tide to work for it. Additionaly, the project provides potential habitats and social programs that locate in different types of elevation, slopes of the new topography that is generated by the new brown earthwork.

By introducing these strategies, the proposal integrate Pandan waterfront to a vibrant and active place by dealing with the brown earthwork, so that it can provide the potential for both habitats establishment and people’s need for safe and stable waterfront space, and additionally adapt to the extreme weather.

RESHAPING COASTAL EDGE LANDSCAPE IN A HIGH-DENSE TROPICAL CITY

Due to urbanization and land reclamation, Sungei Pandan, once the largest mangrove habitat in Singapore, has witnessed a dramatic change of shoreline condition, which caused intertidal habitat loss and fragmentation. With current land use function and edge condition, the lifestyle around Sungei Pandan is detached from the original coastal characteristics, which leads to lack of public awareness for coastal habitats conservation. The project aims to revive coastal habitats under high-density urban context, by shaping a more diverse coastal edge along the Pandan River at the most representative and critical site of the whole area, the middle part between two canals, as a coastal park to benefit the whole community.

The project applies three strategies to reshaping the coastal edge landscape. Firstly, to diversify landform and shoreline, a shallow branch of water is introduced into the site where both shoreline and waterfront are redefined into natural forms. This creates a heterogeneous hydro condition such as brackish pond and riverine estuaries which expands the intertidal zones.

Secondly, by accommodating various habitats, the whole site is divided into active/passive recreation and restoration zone. Coastal, freshwater and urban habitats are then placed to accommodate the hydrological conditions which engage urban with natural area.

Lastly, the project integrates development into coastal habitats with both education and recreation activities that are arranged closely with nature based on habitats distribution. Community activities happen mostly in the northern part of the site, while housing and passive recreations are placed in the southern part. Mangrove restoration project is mainly placed on the new island. Jogging and biking tracks connect the whole site and implementation of boardwalks, treetop walk and aerie tower allow people to go through these coastal habitats.

The project provides a showcase of coastal habitat for public, in which human activities and coastal landscape are integrated together. A biophilic lifestyle would become widespread while people are unconsciously influenced here.

REFLECTIONS

This semester’s studio gave me a new perspective when approaching design. We were taught about the importance of site research and how it helps and informs the progress of our design. Detailing the issues about the site helps to make the project more personal, in my opinion. That is why tackling the problems I saw on site encouraged me to make a change in the urban fabric. I had enjoyed being on site and studying the faunas and their behaviours. It was an eye-opener for me, as previously birds and other animals were never taken into consideration as part of the landscape. Although it was a struggle at first, I loved how the studio encouraged each other and pull it through until the end. It was a bittersweet victory, and I can’t wait to see what’s in store for us in the future.

The studio has been a fruitful and memorable experience as my first learning exposure through the design process of landscape architecture. Thanks to all the teamwork, guidance, and sharing from studio colleagues, experts and practitioners, I was enabled to derive more comprehensive and consolidated perspectives concerning coastal habitats and their compromised condition incurred by high-dense urban development, simultaneously, exploring into ecological potentials that we could leverage on for resolutions of such tensions. Through this studio, I start to be inspired by dealing with diversified opportunities and challenges, as our role of being landscape architects, in creating social and ecological impacts in progressive ways, and to really think critically for achieving the optimisation of both sides (urban and nature) of values, through design interventions.

Though it is not an easy journey understanding the phenomenon of our depleting coastal landscape of Singapore, it was fulfilling to discover, investigate and imply on our gained knowledge to create different solutions that tackle critical issues of the site which other parts of the tropics are potentially facing. The importance of landscape architecture is apparent particularly on how we strive in balancing the ecology, economics and social aspects of Sungei Pandan, in both the existing and new development conditions to create various design proposal that serves as alternatives which our highly-advanced country can adopt when responding to such valuable sites with great ecological attributes. Overall, this experience has taught me to be courageous in exploring new landscape design ideas, pushing my creativity and analytical skills which is an essential attitude that I will carry throughout my design education and career.

This module aims to restore the coastal landscape in a future high-dense residential area by following the natural process which is an important concept for landscape architects to learn. Since uprising spread of hard surface in the modern urban area, the natural resource like the lake, soil, grassland, mudflat, marshland are all replaced by the concrete and steel, where natural succession is no longer familiar to urban dwellers and the species habitats are disappearing dramatically. It’s the call of duty for landscape architects to remind people what’s the natural environment looks like by mimicking the natural process. And meanwhile, dealing with environment issue and mitigate the conflict between human and nature is exactly what we are doing. I hope I can find more innovative way to build more ecological, vibrant and safety urban environment in the future.

This module gives me a vital experience in engaging issues related to landscape architecture in super urban cities. It pushed me to learn the land, people and vegetation in this dense environment. It helps me to know how intensive site research is and how it forms our design. Also, I have gained a new perspective on landscape design by learning to design ecologically.

This first MLA studio gave me a quite different learning experience, and I have learned a lot. Firstly, this studio taught me the importance of the way of thinking. Critical thinking was needed during the whole design process and keep asking myself why made my design more logical. Secondly, this studio focused on ecology, which I did not pay much attention before. It was meaningful to learn how to coordinate the relationship between nature and human, and it is also a new angle for me to see problems. Thirdly, I tried to use geodesign method during the design process and learned lots of knowledge about the constructed wetland with the push of the tutors. Also, I think my presentation skill still need to be improved, and I believe that everything I learned will be useful for me to explore in the future study.

The first studio in MLA is quite different from what I learned during my undergraduate period, and it really gives me a new way of thinking and designing.Moreover, this studio mainly focuses on ecological landscape design, which is a new field for me, and I found it is quite tricky in the beginning. Facing the conflicts of habitat loss and high-density urban development, I learned to find out the most suitable strategies based on site researchers. What I focused on in this studio is brownfield restoration. As I attempted to utilise the remediated brown earthwork to manage storm runoff while to provide potentials for habitats and recreation programs, I began to know that landscape does not just mean beautiful things, we should add more values and functions to it. Lastly, I believe these gains will help me explore more knowledge in the landscape field in the future.

This is the first design studio in MLA program, which mostly focuses on ecology. After we found our issue, we tried our best to find a new harmonious relationship between human and nature, with a hope of contributing to Sungei Pandan. In this studio, I learned how to fully utilise the existing resource in our hands, how to make full use of the data we have and how to think critically, then we can turn the constraints into opportunities and do a more innovative design. Not only in Singapore, we need to do like this, but also in the world with an increased acute contradiction between human and nature, we still need to do this, this is the responsibility of a landscape architect.

Undergoing the very first MLA Ecological studio which is very relevant in today’s’ Singapore context, gave me a wider scope of lens on how I could view, think, process and design landscape critically in a holistic manner. was intrigued by how important our coastal landscape is in Singapore, on how it has morphed and depleted. Most importantly how we as landscape designers could do our part to preserve, enhance and enrich our evolving coastal landscape which is in the phase of depletion. The site visits were beneficial and refreshing as it allowed myself to experience the coast, get immersed in the atmosphere and environment and stay connected with the people in the district. The process of this studio was the most important to me as it showcases the consistency, progression and development through the various mediums such as specific research, site study and essay reading. I would apply what I’ve learned to the upcoming studios in the next few semesters.

This semester’s experience was to me a definite ‘culture shock’. It has broadened my horizon by letting me peek into the world of landscape. It is mind-blowing to me regarding how much intricate details and data go into the whole planning process. Previously thought that landscape was all about design and that having the artistic sense would be fundamental to its success. Having gone through one semester, however, realised that the logical and practical aspects of it matter so much more. Its multi-faceted thinking required for a thorough planning stretched me beyond what would have imagined. I have come to appreciate and respect the fact that humans do not lord over nature. In fact, the wildlife is very much an essential part of the ecosystem, and hence we should take special care to share the same space in harmony, and this is precisely where landscape design can play such a vital role in finding that delicate balance in dividing the area between wildlife and human.an.

This studio gave me a new understanding of ecological design. The completion of the design does not mean that the project is completed, whether it achieves the desired goal and the ecological evolution in the process is also something that we need to focus on. The ecological design should be a process of science, and science is to find the characteristics of a general rule, so regarding design results, a reasonable design should include a complete set of ecological design evaluation standards. Also, our design should adapt to the site over time. Therefore, the ecological design should be based on the site, not just stay on the papers.

I’m glad that survived since there were so many challenges throughout the studio. It’s the first time that nature becomes the main priority where green spaces are no longer simply labelled as green visual like my previous learning experience of urban planning. By understanding the site condition in numerous dimensions, we learned how the natural process works in the high-density urban context. Based on these analyses, we formed individual narratives in imagining a new Pandan Coast. It’s quite tricky to implement measures to coastal landscape due to its dynamic tidal conditions and changes. As I try to prove with my design that it’s possible for us to accommodate with the natural process and blurred boundary rather than separating the coastal nature and our daily life by putting a solid seawall everywhere. In all, this studio expanded my understanding towards nature and design, I’m expecting to explore more detailed environmental issues in the following semesters.

The first MLA studio is a challenge for me, and it gave me an entirely different view towards landscape architecture. We started with the research of the site by kayaking in the pandan river, and I never feel such close to the nature like this before. think it is a good experience from which we can learn the natural process, the animals, the vegetation and feel the relationship between them in ourselves. What I also learned from the studio is that ecosystem must be emphasised and considered when we start our design because even a small area can affect the system and people are also as a part of the system. Moreover, the critical and logical thinking has always been emphasised during the studio process, I try to express myself in every presentation, and through this, I become a little confident to express myself. All in all, although the study process may be a hard challenge for me, will keep on going.
