The module focuses on the functions of the biophysical environment of the city-state of Singapore. The topics include geology, soils, river systems, water supply, nature reserves, green areas, land reclamation and coastal environments. The environmental problems that arise from the rapid urbanization and development of a large tropical city within a limited area and the possible solutions for such problems will be examined. This module emphasizes current events in Singapore and discusses what Singapore’s environment may look like in the future. The module does not require an extensive science or mathematics background, but it does require a willingness to stretch yourself and learn outside your comfort zone.
