Quantifying the Water-Energy-Food Nexus: Current status and trends

Water-energy-food (WEF) interconnection quantifications encounter methodological hurdles. In addition, existing calculation results are scattered across a wide collection of studies in multiple disciplines, which increases data collection and interpretation difficulties. To advance robust water-energy-food (WEF) nexus quantifications and further contribute to integrated WEF systems modeling and management, this study: (i) summarizes the estimate results to date on WEF interconnections; (ii) analyzes methodological and practical challenges associated with WEF interconnection calculations; and (iii) points out opportunities for enabling robust WEF nexus quantifications in the future.
