This report describes efforts made during 1990 by UNICEF and other organizations on behalf of the world's children. Nations attending the World Summit for Children in September committed themselves to achieving objectives to enhance the development of children by the year 2000. Efforts to benefit children in 1990 included programs dealing with immunization, diarrhea, AIDS, guinea worm disease, primary health care, and nutrition. Other programs to help children concerned basic education, sanitation, urban services, childhood disability, women's development, emergency relief, and interagency cooperation. In 1990, advocacy on behalf of children was enhanced by: (1) the mobilization of UNICEF's resources in conferences, publications, and education; (2) participation by the public, nongovernmental agencies, and national committees in children's programs; (3) the support of world celebrities; and (4) the increased success of UNICEF's greeting cards and similar operations. Efforts profiled in this report include projects to help AIDS orphans in Uganda; expand the New School program in Colombia; construct latrines in Lesotho; provide loan credits to women in Nepal; establish day camps for children in Lebanon; and poll children in Ecuador and Costa Rica on the Convention on the Rights of the Child. A series of maps, tables, and charts describing UNICEF's programs, income, and other aspects of UNICEF, is provided. (BC)
