Through this approach a framework is provided under which communities can protect environmental resources by using resources efficiently, create efficient infrastructures, protect and enhance quality of life, and create new businesses to strengthen their economies (US Dept. of Energy, 2001). Ecosystems management attempts to deal with complex environmental issues by fostering sustainable development that recognizes the complex web of natural, economic, social and political factors that affect environmental systems. Effective management of these systems requires an understanding of their properties and in particular knowledge of the dynamics of these systems, and the cultures that rely upon them (Mäler, 2000).

A report emanating from this study states alarmingly that ‘The current rate of decline in the long-term productive capacity of ecosystems could have devastating implications for human development and the welfare of all species’ (United Nations et al., 2000, p. 6).
