Local experts and officials from participating countries also met for the third meeting of the Task Force on the Water-Food-Energy-Ecosystems Nexus (April 2015), and consultations were held in countries linked to the NPD on IWRM. Findings were also presented and discussed in meetings of the energy sector, most notably at the Forum on Energy for Sustainable Development (Baku, 2016 /Astana, 2017), and in the Thematic Working Group on Wa-ter-Energy-Environment of the United Nations Special Programme for the Economies of Central Asia (SPECA).
