A career diplomat, Mr. Sha Zukang became the United Nations Under-Secretary-General for Economic and Social Affairs on 1 July 2007. As such, he heads the Department of Economic and Social Affairs, which is responsible for the follow-up to the major United Nations Summits and Conferences, and services the Second and Third Committees of the General Assembly, the Economic and Social Council as well as the vast majority of its functional commissions and expert bodies. He also convenes the Executive Committee on Economic and Social Affairs, the UN Secretariat’s network for joint planning and initiatives on development.

Mr. Jose Antonio Ocampo

Mr. Ocampo came to the post after almost six years as Executive Secretary of the United Nations Economic Commission for Latin America and the Caribbean.

On arriving at DESA, Mr. Ocampo took it upon himself to advance the quality of DESA’s analytical work. His main achievement in this area was restructuring two of the Department’s flagship documents, the World Economic and Social Survey (WESS) and the World Economic Situation and Prospects (WESP). WESS was transformed into a high quality report on major global issues such as migration, financing for development, diverging development patterns and development in an aging world. WESP was consolidated as the major UN report on short-term world economic conditions, as a joint project of DESA, UNCTAD and the United Nations regional commissions- the core members of the Executive Committee on Economic and Social Affairs (EC-ESA).

The former Under Secretary-General also invested significant time and effort into facilitating the UN Development Agenda which emerged from the various UN summits and Conferences of the 1990s onwards. This task involved supporting the UN intergovernmental process, including joint support from members of EC-ESA. It also involved improving follow-up to the Millennium Development Goals (MDGs) through the work of the interagency statistical team led by DESA’s Statistics Division, the issuance of special annual reports on the MDGs and incorporating the agreements of the 2005 World Summit into the MDG agenda.

Mr. Ocampo also did much to improve the machinery of UN Economic and Social Council (ECOSOC). A major accomplishment here was transforming and broadening the agenda of the old “ad hoc” working group of international co-operation on tax matters, which became a regular technical organ of ECOSOC. Major reforms were proposed for ECOSOC itself as part of the process leading-up to and following the 2005 World Summit. Some of these were implemented under Mr. Ocampo including the creation of the development co-operation forum and the high-level follow-up to the UN Conferences and Summits.

Mr. Nitin Desai

In March 1997, Nitin Desai was asked to co-ordinate the consolidation of the three economic and social departments in the United Nations Secretariat in New York into the Department of Economic and Social Affairs (DESA).

DESA was charged with providing substantive support to the normative, analytic, statistical and relevant technical co-operation work of the UN in the economic and social sphere. Mr. Desai was subsequently asked to head this department.

He was also designated as the Convenor of the Executive Committee on Economic and Social Affairs, which brings together the heads of all UN Secretariat entities directly concerned with economic, environmental and social issues.

In his capacity as Under Secretary-General for Economic and Social Affairs, Mr. Desai provided vital leadership to the special sessions of the General Assembly which reviewed progress made five years after the global conferences on sustainable development (1997), and on population and development, small island development states, advancement of women, and social development (2000).

Under his guidance, DESA organized three other major conferences; the International Conference on Financing for Development in Monterrey, Mexico, the Second World Assembly on Ageing in Madrid, Spain and the World Summit on Sustainable Development in Johannesburg, South Africa, for which he served as Secretary-General.
