It aimed to foster transboundary cooperation by identifying intersectoral synergies and determining measures to alleviate tensions related to the multiple needs of basin countries for common resources. The process drew upon the experience and expertise of key actors to strengthen the knowledge-base for decision-making. It identifies actions to help respond to the challenges of managing the interlinked water, food and land, energy resources and ecosystem services in the basin.
