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.

Holistic Water-Energy-Food Nexus for Guiding Water Resources Planning // Matagorda County, Texas Case

By Muhammed I. Kulat, Rabi H. Mohtar and Francisco Olivera. The authors developed a holistic framework to provide sustainable scenarios that include feasible infrastructure interventions. The framework focuses on water and associated links with other resources, includes a unique analytic tool for quantifying scenarios, and ultimately produces a sustainability analysis of each scenario. Optimal scenarios are offered that consider site-specific dynamic resource interlinkages. The WEF nexus model...

Pompage Solaire // Investigation de l’impact des installations de pompage solaire sur la consommation d’eau et la situation socio-économique d’un agriculteur dans 3 zones pilotes au Maroc

Cette étude vise à mieux comprendre comment la conversion au pompage solaire peut influencer la consommation d'eau et les conditions socio-économiques d'un agriculteur marocain par rapport aux autres systèmes de pompage d'eau. L'étude s'est appuyée sur une enquête menée auprès de 150 agriculteurs répartis sur les territoires suivants 3 zones distinctes : la zone de Marrakech, la zone de Midelt et la zone de Tata. L'étude a été réalisée par le projet GIZ Sustainable Energy for Food - Powering...

WEF Nexus Research // Engaging Stakeholders in Research to address Water–Energy–Food (WEF) Nexus Challenges

By A. Larkin, C. McLachlan, R. Falconer, I. Soutar, J. Suckling, L. Varga, I. Haltas, A. Druckman, D. Lumbroso, M. Scott, D. Gilmour, R. Ledbetter, S. McGrane, C. Mitchell, D. Yu. This paper reflects on recent progress in stakeholder engagement in nexus-related research. The authors outline four emerging themes within nexus research and consider the value of, and potential challenges for, transdisciplinary research in each. Specifically, the authors examine how transdisciplinary approaches are...
