The Economic and Social Council, under the overall authority of the General Assembly, coordinates the economic and social work of the United Nations and the UN family of organizations. As the central forum for discussing international economic and social issues and for formulating policy recommendations, the Council plays a key role in fostering international cooperation for development. It also consults with non-governmental organizations (NGOs), thereby maintaining a vital link between the United Nations and civil society.
The Council has 54 members, elected by the General Assembly for three-year terms. It meets throughout the year and holds a major session in July, during which a special meeting of Ministers discusses major economic, social and humanitarian issues.
The Council's subsidiary bodies meet regularly and report back to it. The Commission on Human Rights, for example, monitors the observance of human rights throughout the world. Other bodies focus on such issues as social development, the status of women, crime prevention, narcotic drugs and environmental protection. Five regional commissions promote economic development and cooperation in their respective regions.
