Agenda 21 (UNCED 1992) provides the blueprint for implementing sustainable development agreed at the 1992 Earth Summit (and approved by over 170 nations). This substantial document covers an enormous number of environment and development issues, with forty chapters ranging from 'Changing Consumption Patterns' and 'Combating Deforestation' to 'Children and Youth in Sustainable Development' and 'Strengthening the Role of Farmers'. Indeed, a key feature of Agenda 21 is that it does not confine itself to the traditional agenda of environmental degradation and conservation, but devotes considerable attention to the political, economic and financial aspects of sustainable development. Thus twenty-five of the forty chapters focus on non-ecological issues.
