Dr. Noeleen Heyzer, a social scientist, was former Under-Secretary-General of the United Nations and the highest ranking Singaporean in the UN system (2007-2014).

She was the United Nations Secretary-General’s Special Adviser for Timor-Leste, working to support peace-building, state-building, and sustainable development.

She was the first woman to serve as the Executive Secretary of the United Nations Economic and Social Commission for Asia and the Pacific (ESCAP) since its founding in 1947. Under her leadership (August 2007-January 2014), ESCAP has grown in profile and stature, focusing on regional co-operation for a more resilient Asia-Pacific, founded on shared prosperity, social equity, and sustainable development. She was at the forefront of many innovations including for regional disaster preparedness, inclusive socio-economic policies, sustainable agriculture and urbanization, energy security, regional connectivity and integration as new drivers of growth.

As the Executive Secretary, she strengthened ESCAP’s capacity and effectiveness to support the countries of the region, using its convening powers and standard-setting authority, rigorous analysis, technical and policy assistance to build the economic and social foundations for inclusive and sustainable development. She worked with key political leaders and decision-makers in 54 Member States to shape regional policy agendas for Asia Pacific’s transition towards sustainable and shared prosperity, and established regional cooperation mechanisms to address the “new normal” of volatility, such as the food-fuel-finance crises and climate change. She focused on harnessing development opportunities through multi-stakeholder alliances and partnerships to sustain development gains, reduce poverty and inequalities, transforming the quality of people’s lives.

Among the many significant achievements of the region, under her tenure with ESCAP, have been groundbreaking intergovernmental agreements on a regional intermodal transport and logistical system, especially for landlocked developing countries; and initiatives such as Regional Connectivity including assistance in the formulation of ASEAN’s Connectivity Master Plan, exploration of an Asia-Pacific Energy Highway, an ICT super-highway, and the negotiation supporting the new Silk Route of economic development in Central Asia. Other major milestones are the regional action plans on inclusive socioeconomic policies and social protection; the strengthening of vital statistics and civil registration; financing and technology for an inclusive and green future; the building of productive capacities of Least Developed Countries, secure employment in vulnerable communities, and the empowerment of women and youth. She was also responsible for the establishment of ESCAP’s works on resilience to man-made and natural disasters, and the stewardship of water, energy and natural resources especially for small islands states, least developed and landlocked countries.

In 2009, Dr. Heyzer led an unprecedented dialogue with Myanmar’s leaders on development and poverty reduction, resulting in the Government of Myanmar requesting the formation of a development partnership that has allowed practitioners and eminent international scholars, such as the Nobel Prize economist Professor Joseph Stiglitz, and local researchers to exchange experiences and ideas with government agencies and civil society. This has been regarded by many as helping to catalyze the opening-up of the country from its former isolation. In 2008, she also worked closely with ASEAN, the Government of Myanmar, and the UN in the recovery efforts assisting cyclone-affected people in the Ayeyarwady Delta.

Prior to her appointment to ESCAP, Dr. Heyzer was the first woman from the South to head the United Nations Development Fund for Women (UNIFEM).

Dr. Heyzer has also advised private sector partners such as Macy’s, CISCO, and the Calvert Investment Fund to provide high value employment and market access to women and youth in conflict and disaster-affected areas as well as in the Arab States, setting new standards for ethical investment.

As the highest ranking UN official, Dr. Heyzer was also responsible for the security and safety of the UN system, staff and their families in Thailand during the intense political violence that regularly erupted over her six year tenure, and during the country’s worst floods in 2011-2012.
