Developing environmental education material

This strategy features in the framework of Agenda 21 as formulated at UNCED (Rio de Janeiro, 1992), now coordinated by the United Nations Commission on Sustainable Development and implemented through national and local authorities. Agenda 21 recommends that educational materials of all kinds and for all audiences should be based on the best available scientific information, including the natural, behavioural and social sciences, and take into account aesthetic and ethical dimensions.
