providing support for implementation of programmes as requested by Member States;

promoting and supporting research in priority areas to facilitate programme implementation and evaluation, in close collaboration with organizations of the United Nations system and other intergovernmental bodies (FAO, UNESCO, UNICEF, United Nations University and others), research institutes and other partners;

working with FAO and other organizations of the United Nations system, the World Bank, and research institutes on their evaluation of implications of the Strategy for other sectors;
