The need to define sustainability broadly and the general overuse of the word ‘sustainability’, has made the most acceptable definition the one espoused in the Brundland Report, that is, ‘management and conservation of the natural resource base and … attainment and continued satisfaction of human needs for the present and future generations’ (WCED, 1987).This definition continues to be valuable for decision makers because it identifies the overarching goals that need to be included in a sustainability assessment.This is why the same definition still needs to be espoused. The 2002 World Summit on Sustainable Development held in Johannesburg, South Africa, used similar terms when asking participating countries to ‘ensure a balance between economic development, social development and environmental protections as interdependent and mutually reinforcing pillars of sustainable development’ (UN, 2002).
