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 emphasizes the importance of continued active and effective participation of non-governmental organizations, of the scientific community and the private sector and of local groups and communities in the implementation of Agenda 21. It recommends that relevant non-governmental organizations, including the scientific community, the private sector, women's groups, etc., should be given the opportunity to make their contribution and establish appropriate relationships with the UN system. Support should be provided for developing countries' non-governmental organizations and their self-organized networks. Agenda 21 also recommends that UNDP should promote and strengthen the role and involvement of women, youth and other major groups in recipient countries in the implementation of Agenda 21.
