Since the 1980s, he has also worked with many international organisations. While at the United Nations' Department of Economic and Social Affairs, Jomo led the response to the 2005 Summit call to help Member States develop national development strategies to achieve the internationally agreed development goals, while promoting their greater coherence as the United Nations Development Agenda. Jomo has tried to ensure greater UN system-wide collaboration in report preparation including the annual World Economic and Social Survey and biennial Report on the World Social Situation. Jomo was also a Research Coordinator for the G24 Intergovernmental Group on International Monetary Affairs and Development during 2006–2012. During 2008–2009, he served as adviser to Father Miguel d'Escoto Brockmann, president of the 63rd United Nations General Assembly. Together with the Bank of International Settlements, the UN and the G24 – under his leadership – have been acknowledged as the only international organizations who warned of the impending 2007–2009 crisis. In response to the crisis, he initiated the UN system-wide supplementary Macroeconomic Advisory Capacity to offer 'second opinions' on appropriate policy responses emphasizing economic recovery and employment generation, served as a member of the Stiglitz Commission of Experts of the president of the UN General Assembly on Reforms of the International Monetary and Financial System during 2008–2009, and led a parallel effort for the G24 to articulate international financial system reform proposals. Jomo served as the United Nations assistant secretary-general for economic development in the United Nations Department of Economic and Social Affairs (DESA) during 2005–2012, and then as assistant director-general and coordinator for economic and social development at the Food and Agriculture Organization of the United Nations in Rome during 2012–2015. From 2010 until he departed UN DESA, he served as the G20 'sherpa' to UN Secretary-General Ban Ki-Moon besides serving as G20 finance deputy for the UN since 2011. In these different capacities, he has worked to build an international consensus to ensure UN system-wide coherence, complementary economic and social policies for balanced and sustainable development, appropriate investment incentives, employment generation and, more recently, a strong and sustained economic recovery. Jomo has addressed ministerial meetings of UNCTAD, most UN regional commissions, Funds and Programmes, several UN agencies as well as ECOSOC
