With its comprehensive coverage of political and security matters, human rights issues, economic and social questions, legal issues, and institutional, administrative and budgetary matters, the Yearbook of the United Nations is the most authoritative reference work available on the activities and concerns of the Organization. Fully indexed, the Yearbook includes the texts of all major General Assembly, Security Council and Economic and Social Council resolutions and decisions.




During 1990, the United Nations continued to play a central role in assisting the Central American countries to achieve peace. UN peacekeeping operations in the region required adjusted mandates to cope with their expanding roles. The United Nations Observer Group in Central America (ONUCA), set up originally to promote compliance with agreements reached by the five Central American Presidents, was instrumental in the voluntary demobilization of the Nicaraguan resistance. On five occasions during the year, the Security Council enlarged and extended ONUCA’s mandate: on 27 March, 20 April, 4 May, 8 June and 5 November. The United Nations Observer Mission for the Verification of the Electoral Process in Nicaragua (ONUVEN) monitored preparations for and the holding of free and fair elections in February, the first such operation authorized and conducted by the Organization internally in a Member State. ONUVEN’s success led to a central role for the Organization in the peaceful transfer of power in a region where, in the past, such transfers had been the exception rather than the rule.
