Later, in his role as the Director of UN-Habitat in New York, he played a strategic role within the UN Development Group (UNDG) which led to increased coordination of initiatives on water, sanitation and slum upgrading at country level. More recently, in Washington DC, he worked to promote enhanced understanding of and access to clean drinking water and sanitation, and advance these policy issues within the context of sustainable urban development focused on low-income populations in developing countries.
