Agenda 21 recommends facilitating the organizational review of government ministries and agencies responsible for land questions, in order to devise more efficient mechanisms of land-resource management, and carrying out periodic in-service refresher courses for their managers and staff in order to familiarize them with up-to-date land-resource management technologies. Agenda 21 also recommends training communities, relevant extension services, community based groups and NGOs on land management techniques and approaches that have been successfully applied elsewhere.
