The web site of the UNDESA Division for Sustainable Development includes information on the Commission on Sustainable Development, Agenda 21 and the nine Major Groups recognized for their specific roles and responsibilities: Women, Children and Youth, Indigenous People, Non-governmental Organizations, Local Authorities, Workers and Trade Unions, Business and Industry, Scientific and Technological Communities, and Farmers. Agenda 21 also stipulates the need for new forms of participation at all levels to enable a broad-based engagement of all economic and social sectors in making sustainable development happen.
