Water, Energy, Food (WEF) Nexus Project

Water, energy and food security is an urgent global concern, and there is a critical need for a nexus approach that recognizes the inter-relationship between these resources. Researchers at UC Davis and the Arab region have been exploring potential opportunities to leverage their separate work on the intersections of water, energy and food.  The Arab region shares similar challenges with California: water access as a limiting factor in food production; food waste in the harvesting, processing, and increasing waste in the consumption phases; and high agriculture and food processing energy costs.  The UCDAR (UC Davis and Arab Region) Consortium established a Water-Energy-Food Nexus Committee comprised of researchers from the partnering universities in the region and from UC Davis to collaborate on a new project to apply a Water-Energy-Food (WEF) Nexus framework to identify innovative solutions to minimize loss and waste in agriculture and food production in order to ensure water, energy and food security for future generations.  The project: “Minimizing the Losses of Water, Energy and Food throughout the Agriculture and Supply Chain Processes,” will examine WEF Nexus case studies in Egypt, Lebanon, Palestine, UAE, and the U.S. (California) to identify country/region-specific challenges and opportunities, and share strategies and practices that can be applied in areas with similar conditions.

The working group met for two days at UC Davis in January 2018 to address critical issues and research opportunities in water and energy efficiencies and food loss reduction in agricultural and food processing.  The aim was to form a strategic partnership for short and long term knowledge production and dissemination.  At this meeting, Andre Daccache, Assistant Professor in the UC Davis Department of Biological and Agricultural Engineering agreed to assume leadership for planning collaborative opportunities.  The workshop was funded through a Global Affairs Seed Grant with matching funds from the College of Agricultural and Environmental Engineering, the College of Engineering, and the Sustainability Research and Training Program.
