In the webpage "Sustainability Effort" (n.d.) taken from Gardens by the Bay website reported about the key function of the Gardens as an ecosystem that able to self-sustain in a environment. The ecosystem works by themselves without much maintenance issues to achieve environmental sustainability. These systems comprises the Lake system, the Conservatories and Supertrees. The Lake systems acts as a biotope that accommodates the aquatic animals and plants which later on helps to cleanse the surface run-off as well as the lake itself. Subsequently, the cleansed water is then discharge in Marina Reservoir and also used for irrigation purposes. Besides the Lake systems, the webpage also mentioned about the Conservatories. The two biomes are equipped with advanced technology allowing it to simulate the climate temperature suitable to certain region to accommodate rare plants in Singapore. It also mentioned in webpage further about Supertrees which are equipped with solar planes. These allows the trees to harvest electricity in the day hence reducing the amount of electricity used at night. These environmental efforts can make huge improvements such as reducing the carbon emissions in the atmosphere. Therefore, I agree that this initiative effort should be supported in Singapore.
In 2006, Public Utilities Board (PUB) has launched Active, Beautiful and Clean water programe (ABC water programe) to promote the improtance of water quality and appreciate water resources. As most of the water supply in Singapore are from the local catchment, water quality flowing into the reservoir need to be control to prevent unwanted pollutants. Therefore the water agency in Singapore need to find ways to make the water quality better in the drain, canals and riverbanks before entering the reservoirs. Sustainability is the main idea of PUB as it require less maintenance thus it create a whole new ecosystem in a community. This is mention in PUB webpage (2016) that ABC water programme is introduce to enhance water and life quality by combining the drain, canal and reservoir with the surrounding environment. Hence it transform the garden into an ecosystem that able to self sustain. According to Susdrain (n.d.), UK drainage systems are transformed into a sustainable drainage that allows rain and surface water run-off to cleanse naturally by allowing water to soak in the ground thus filtering unwanted pollutants.
Secondly, this initiative is not only cleansing the water runoff quality but also Bishan-Ang Mo Kio Park( (2014, Section 10)) is a great example of PUB ABC water project which uses a similar concept to Gardens by the bay. This idea was echoed in PUB’s webpage (2006), this programme is to transform all the drains, canals and reservoirs in Singapore into beautiful and clean streams hence bring the community closer to the nature. This environmental sustainability effort can be made into smaller scales such as parks near HDB houses as well as condomium, hospital and also schools. These way sustainability efforts can spread widely across Singapore hence improving the ecosystem as well as the aesthetic of the environment. In the ABC water guideline book (2014, Section 10) suggests that parks such Bishan-Ang Mo Kio park and public hospital like Khoo Teck Puat hospital have benefited from environmental sustainability concept.
Moreover, communities get to enjoy the recreational spaces and conscious about the nature. In additional, these efforts would make Singapore a greener city. Because of this reason, Ministry of Environment and Water Resource has initiated the 1st edition of Active, Beautiful and Clean water guideline (ABC water guidelines) in 2009 which basically to encourage developers in Singapore to adopt ABC Waters design features in their developments. Bishan-Ang Mo Kio Park is a great example of PUB ABC water project which uses a similar concept to Gardens by the bay however in smaller scale. According to Ramboll, it stated that Bishan-Ang Mo Kio Park was reconstructed from the conventional concrete drainage to bioengineered riverbank by incorporating the living plants to act as river walls. These plants are there to function as a filtration system as well as aesthetic of the drainage. Hence, transforming the space to be closer to water and nature.
Apart from Singapore, other countries such as United Kingdom are also implementing a similar concept of sustainable development in their country. According to Susdrain (n.d.), UK drainage systems are transformed into a sustainable drainage that allows rain and surface water run-off to cleanse naturally by allowing water to soak in the ground thus filtering unwanted pollutants. This is similar to the concept that PUB adopted. However, UK project are much larger in scale than Singapore. Thus, the impacts in the ecosystem are obviously noticeable. Examples of problems solved are the reducing the amount of energy and cost to treat rainwater.
