Science Forum 2018 Case Study // Energy Checklist for Asia’s Irrigation Projects

By Hua Xie, Van Manh Nguyen, Claudia Ringler, Yasmin Siddiqi. This case study "Energy checklist for Asia’s irrigation projects: increasing crop water productivity without increasing energy use in agriculture" discusses the energy checklist developed for irrigation managers and tested on high-value crops in the Central Highlands of Vietnam.

Asia accounts for more than two thirds of irrigated area in the world, much of it still gravity-fed; about 85 percent of all water withdrawn in the region is used for irrigated agriculture. Given growing pressures from industries and cities, and incipient demands for enhanced environmental flows, there is increasing pressure to modernize Asia’s irrigation systems to increase efficiency and to move water toward additional irrigation, but also increasingly urban-industrial uses. However, irrigation managers in charge of modernizing systems are seldom aware of the full range of energy linkages of existing and planned irrigation systems, and heavily energy-dependent modernization projects might fail to meet expectations if the many demands on energy sources, such as for pumping water and applying it to the field, for agricultural chemicals and machinery services, and for ensuring that outputs can be profitably brought to market cannot be fulfilled.

Modelling and Assessment

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...
