The Water-Energy-Land Use-Ecosystems Nexus Methodology for Transboundary Basins has been developed specifically for shared water bodies, to assess intersectoral linkages, trade-offs and benefits. It has been developed under the United Nations Economic Commission for Europe (UNECE) Convention on the Protection and Use of Transboundary Watercourses and International Lakes (Water Convention) to assess a representative set of transboundary basins in the pan-European region and beyond as part of the Water Convention's Work Programme 2013-2015. A methodology for assessing the water-food-energy-ecosystems nexus in transboundary settings has been developed, including a governance component. These will develop and get refined upon application to different basins. The process has initiated an intersectoral dialogue in some basins to also look at the institutional framework and functioning of intersectoral governance. A broader understanding of benefits of transboundary coordination and cooperation and functioning of governance is expected to emerge.
