GREEN SPACES IN THE URBAN ENVIRONMENT
Hence, it is imperative that sufficient green spaces are allocated by local authorities. According to the World Health Organisation (WHO), between 10 and 15 square metres of green space per inhabitant are needed to ensure a healthy urban ecosystem.
The value of greenery in a particular development can be broadly divided into three categories, ie. environmental (ecosystem services), ecological (enhance urban biodiversity) and social (aesthetic and psychological benefits). Examples of green spaces include green walls, rooftop gardens, urban farms, vertical farming, wildlife corridors, tree façade, city gardens, etc.
GREEN PLOT RATIO (GNPR)
The Green Plot Ratio (GnPR) was developed by Dr Ong Boon Lay at the National University of Singapore back in 2002 to provide a metric to quantify the amount of greenery in an area. Theoretically using this metric the amount of carbon sequestration, water retention and other environmental benefits of plants can be estimated. This in turn could be used to communicate the value of greenery and to set greenery requirements for projects.
