Case Study Mexico // How Guanajuato’s Water and Wastewater Utilities are tackling Climate Change through Efficiency Optimization and Renewable Energy Production

This case is part of a case study series, where the Water-Energy-Climate Nexus supports the transition towards a more sustainable and low-carbon urban management. In San Francisco del Rincón, two utility companies, SITRATA (Servicio de Tratamiento y Deposición de Aguas Residuales) and SAPAF (Sistema de Agua Potable y Alcantarillado de San Francisco), are collaborating on projects to improve their services and lower their greenhouse gas (GHG) emissions. SITRATA manages wastewater, while SAPAF is responsible for drinking water and sewage. With guidance from the WaCCliM project, both utilities have undertaken a strategizing and implementation process similar to that proposed in the “WaCCliM Roadmap to a Low- Carbon Urban Water Utility”.

As a result, SAPAF have increased wastewater treatment coverage from 48% to 81% and improved the energy efficiency of their pumping stations. The magnitude of the increase in treatment coverage was by far the biggest achievement in GHG reduction.

Publication // The Development of the Water-Energy-Food Nexus as a Framework for Achieving Resource Security: A Review

By Gareth B. Simpson and Graham P. W. Jewitt. This paper presents a study of the evolution of the water-energy-food (WEF) nexus since its rise to prominence in policy and development discourses in 2011. Drawing from an extensive review of published literature, the paper presents various interpretations of the concept while also considering the novelty of the WEF nexus.

Publication // A 40-year review of food–energy–water nexus literature and its application to the urban scale

By Newell, J. P., Goldstein, B., & Foster, A. (2019). What research exists to date on the FEW nexus? How have scholars conceptualized these interactions at the urban scale? What are some promising approaches? Where are the research gaps? To answer these questions, this paper conducts a quantitative review of the academic literature on the FEW nexus (1399 publications) over more than four decades (1973–2017), followed by in-depth analysis of the most influential papers using an evaluation matrix...
