Tree-like structures called Supertrees dominate the 'Gardens by the Bay' landscape with heights of up to 50 metres. These vertical gardens perform a multitude of functions, which include planting, shading and working as environmental engines for the gardens. Fitted with environmental technologies that mimic the ecological function of trees – photovoltaic cells that harness solar energy which can be used for some of the functions of the Supertrees, such as lighting (mimicking photosynthesis in nature); and collection of rainwater for use in irrigation and fountain displays, (mimicking rainwater absorption for growth in nature). The Supertrees also serve air intake and exhaust functions as part of the conservatories' cooling systems.
Gardens by the Bay is an integral part of a 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. Photo by Suzanne Lee/Panos Pictures
