Singapore has planted two million trees in the last 45 years and cleaned up its waterways – part of a campaign that has resulted in it becoming richer in species than any city in the world. Gardens by the Bay is part of the strategy by the Singapore government to transform Singapore from a “Garden City” to a “City in a Garden”. The stated aim is to raise the quality of life by enhancing greenery and flora in the city.
Gardens by the Bay is a nature park spanning 101 hectares (250 acres) in central Singapore, adjacent to the Marina Reservoir. The park consists of three waterfront gardens: Bay South Garden, Bay East Garden and Bay Central Garden. The largest of the gardens is Bay South Garden at 54 hectares (130 acres).
The man-made mechanical forest consists of 18 supertrees that act as vertical gardens, generating solar power, acting as air venting ducts for nearby conservatories, and collecting rainwater. To generate electricity, 11 of the supertrees are fitted with solar photovoltaic systems that convert sunlight into energy, which provides lighting and aids water technology within the conservatories below.
Varying in height between 25 and 50 meters, each supertree features tropical flowers and various ferns climbing across its steel framework. The large canopies also operate as temperature moderators, absorbing and dispersing heat, as well as providing shelter from the hot temperatures of Singapore’s climate to visitors walking beneath.
Each Supertree consists of a trunk core made of reinforced concrete wrapped with a steel frame. Planting panels are installed on the trunks for the planting of the living skin.
Type of Partnership: Win-Neutral for Public and Planet
While this example provides ample Public benefit, and may provide habitats for flora and fauna; the original eco-system habitats pre-dated cities and built environments. Therefore, this example is considered to be neutral for the Planet as opposed to a win-win.
