    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.

    The Water-Energy-Food Nexus: A new approach in support of food security and sustainable agriculture 2014

    If a decision is made at the national level to increase the share of bioenergy, what implications does this have for water, land and energy? How do electricity subsidies contribute to groundwater depletion and what can be done about it? How can we ensure that sectoral policies and strategies consider the potential trade-offs for other sectors? Finding answers to these questions is the main challenge of the Water-Energy-Food Nexus. By describing the complex and interrelated nature of our global r esource systems, the Nexus approach helps us to better understand and systematically analyze how we can use and manage our resources in light of different, often competing interests and goals.

    Water-Energy-Food-Ecosystem (WEFE) Nexus to increase food systems' resilience to climate change and conflict's cascading effects in the Mediterranean region
    Webinar outcomes
    2022
    Also available in:

    During this webinar, organized by the SFS-MED Platform and held on 6 July 2022, stakeholders from across the Mediterranean shared practical experiences of their engagement in adopting WEFE Nexus solutions and demonstrate the more comprehensive socio-economic benefits of their proposed practices on the food system at large, going beyond a fragmented system of sectors and players. Tackling the WEFE Nexus approaches from diverse angles of the Mediterranean food systems, they shared case studies and tangible examples of WEFE Nexus technical solutions applied in the Mediterranean region, reflecting on success factors and challenges, and discussing ways to facilitate replication and upscaling solutions across the Mediterranean, and influence policy change. The discussion was instrumental in demonstrating how the WEFE Nexus could represent a paradigm shift in the international development agenda, moving from disjointed sectoral development interventions to a more integrated resource management and sustainable use. There is a need for transformation towards sustainable food systems that embrace a WEFE nexus approach to promote peace, recovery and resilience, characterized by interdisciplinary research and knowledge sharing, to be applied in practice through multi-stakeholder collaboration. Moreover, bridging the nexus knowledge gap requires capacity building and combined action by the scientific community, policymakers and practitioners on the ground, paired with high-level political will supported by a sound governance system. Last, but not least, technological innovation and nature-based solutions spearheaded by the private sector have the potential to democratize data generation and use and to minimize costs for the sustainable management and restoration of natural resources. For this to happen, there is a need for financial innovation in de-risking and investment mechanisms that target innovative agri-food businesses and incentivize WEFE nexus solutions.
