Evaluating effectiveness of land resource conservation programmes
Implementation:
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 establishing and strengthening national land-resource data banks, including identification of the location, extent and severity of existing land degradation and of areas at risk, and evaluating the progress of conservation and rehabilitation programmes launched in this regard.
