MORPHING FAUNA BARIER IN COASTAL AND URBAN LANDSCAPE

Nur Azilla Nazli

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 Built Structures Identifying buildings suitable for green roofs and vertical greenery that acts like a stepping stones

Maintain some open space with low groundcover

Mimicking Forest Structure Core areas to have multiple layers of forest to accomodate the different needs of different fauna

Retrofitting Industrial Landscape Into Everyday Lives

Yong Keng - Whye, Raymond

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.
