Implementation and Case Studies

Case Study Thailand // How Chiang Mai’s Wastewater Utility is Building Capacity on Sustainable and Innovative Solutions to reduce its Carbon Footprint.

This case is part of a case study series, where the Water-Energy-Climate Nexus approach supports the transition towards a more sustainable and low-carbon urban management. In the city of Chiang Mai, the WaCCliM project supports the Wastewater Management Authority (WMA) in assessing opportunities to reduce its carbon footprint. A baseline study identified the leaks of untreated wastewater, caused by fractured pipes in the wastewater collection system, as the main source of greenhouse gas (GHG) emissions in Chiang Mai. A large amount of untreated wastewater is flowing directly into the public canal. Because of this, the city is producing significant amounts of methane (CH4) and nitrous oxide (N2O), both gases with a larger global warming potential than carbon dioxide (CO2). The emissions from direct discharge of untreated wastewater account for 579,900 kg CO2 per year in the city. The cooperation between WaCCliM and the WMA in Thailand has raised the local awareness for the challenges in the wastewater sector and the need for improvements in the urban water management in order to achieve resilient water utilities. Therefore, knowledge transfer and capacity building are necessary for long-term success and continuous progress.

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...
