This policy brief offers recommendations for researchers, policymakers, and practitioners to improve stakeholder engagement in the process of implementing the Water-Food-Energy-Ecosystems (WEFE) Nexus in river basins. It reflects on so-called Nexus Dialogues carried out across eight case studies within the four-year Horizon 2020 project GoNEXUS. Evidence on how to effectively conduct Nexus Dialogues in river basins, especially in large projects with multiple case studies, is limited and has motivated this policy brief.
