By United Nations World Commission on Environment and Development, 1987

The strategy for sustainable development aims to promote harmony among human brings and between humanity and nature. In the specific context of the development and environment crises of the 1980s, which current national and international political and economic institutions have not and perhaps cannot overcome, the pursuit of sustainable development requires: a political system that secures effective citizen participation in decision making. An economic system that is able to generate surpluses and technical knowledge on a self-reliant and sustained basis a social system that provides for solutions for the tensions arising from disharmonious development. a production system that respects the obligation to preserve the ecological base for development, a technological system that can search continuously for new solutions, an international system that fosters sustainable patterns of trade and finance, and an administrative system that is flexible and has the capacity for self-correction.
