Walking the nexus talk: assessing the water-energy-food nexus in the context of the sustainable energy for all initiative

Due to global transformational trends, such as population growth, economic development and climate change, energy, water, land and human resources are increasingly under pressure to support societal development and to maintain necessary services. Decisionmakers need improved tools in order to be better informed about trade-offs and synergies between different development and management choices, and to help them identify options on how to sustainably manage resources.This report proposes a way to carry out a water-energy-food nexus assessment approach in order to: a) understand the interactions between water, energy and food systems in a given context, and b) evaluate the performance of a technicalor policy intervention in this given context.The ultimate goal of the nexus assessment is to inform nexusrelated responses in terms of strategies, policy measures, planning and institutional set-up or interventions.
