Review Article // Climate Change Adaptation through the Water-Energy-Food Nexus in Southern Africa

By Sylvester Mpandeli, Dhesigen Naidoo, Tafadzwanashe Mabhaudhi, Charles Nhemachena, Luxon Nhamo, Stanley Liphadzi, Sithabile Hlahla and Albert T. Modi. Climate change is a complex and cross-cutting problem that needs an integrated and transformative systems approach to respond to the challenge. This review highlights climate change impacts on water, energy, and food resources in southern Africa, while exploring mitigation and adaptation opportunities. The review further recommends strategies to develop cross-sectoral sustainable measures aimed at building resilient communities. Regional WEF nexus related institutions and legal frameworks were also reviewed to relate the WEF nexus to policy.

What is clear is that climate change impacts are cross-sectoral and multidimensional, and therefore require cross-sectoral mitigation and adaptation approaches. In this regard, a well-coordinated and integrated WEF nexus approach offers opportunities to build resilient systems, harmonise interventions, and mitigate trade-offs and hence improve sustainability. This would be achieved through greater resource mobilisation and coordination, policy convergence across sectors, and targeting nexus points in the landscape. The WEF nexus approach has potential to increase the resilience of marginalised communities in southern Africa by contributing towards attaining the Sustainable Development Goals (SDGs 1, 2, 3, 6, 7, and 13).

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...
