To support this larger population, we need to (a) reclaim additional land; (b) develop some of our reserve land; (c) intensify new developments; and (d) recycle land with lower intensity uses such as old industrial areas and some golf courses to achieve higher land productivity.
Land use and allocation in Singapore is governed by our Master Plan. The Master Plan 2008 is being revised and updated to support the Population White Paper. By 2030, more than half of our land (58%) will be allocated to uses which enable us to live, work and play in a high quality environment. These uses include housing, services and manufacturing jobs, facilities and amenities, as well as green spaces such as parks and nature reserves, essential services and utilities like water and electricity. 19% of our land will support mobility within Singapore and connectivity to the rest of the world. Another 19% of our land will be for our defence needs.
