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for more than two thirds of irrigated area in the world, much of it still gravity-fed; about 85 percent of all water withdrawn in the region is used for irrigated agriculture.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.

The Global Food-Energy-Water Nexus

By Paolo D'Odorico, Kyle Frankel Davis, Lorenzo Rosa, Joel A. Carr, Davide Chiarelli, Jampel Dell'Angelo, Jessica Gephart, Graham K. MacDonald, David A. Seekell, Samir Suweis, Maria Cristina Rulli. Water availability is a major factor constraining humanity's ability to meet the future food and energy needs of a growing and increasingly affluent human population. Water plays an important role in the production of energy, including renewable energy sources and the extraction of unconventional...

Nexus Project Bolivia // Working together to develop the water, energy and food security sectors

The contradictory development objectives for water, energy and food security in Bolivia generate conflicts of interest between ministries, and also between authorities and institutions in the provinces and municipalities: each institution wants to support especially its sector, be it water, energy or rural. For this reason, planning is needed that transcends different sectors, such as that sought by governments at the national and local levels.

Le Barrage de Fomi // Potentiel pour Un Projet d’Intérêt Commun

Par Luca Ferrini & Lucia Benavides. Cet article explique comment le projet de barrage de Fomi, qui a récemment regagné le monumentum, marque une grande opportunité d'intégrer l'approche Nexus dans le processus de planification comme un outil d'aide à la décision. Situé en Haute Guinée, à la tête du bassin du Niger et dans une zone aride affectée par le changement climatique et l'insécurité, la construction du barrage de Fomi poserait à la fois de nombreux risques et défis ainsi que des...
