1.2. Sustainable development indicators
In less than two decades, since the idea of sustainable development became established in policy and academic circles, the number of indicators produced has become daunting.
International, national, local, public and private organizations have all embarked on efforts to
provide measures of nature’s and society’s long-term ability to survive and prosper together, as well as to guide planning and policy making. Indicators have been identified as desirable instruments and/or measuring rods to assess and monitor progress towards sustainable development (Selman, 1999).
