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for more than two thirds of irrigated area in the world, much of it still gravity-fed; about 85 percent of all water withdrawn in the region is used for irrigated agriculture.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

Learning // The Nexus Game

The Nexus Game gives participants a unique opportunity to get an insight into the challenges of water management for producing energy and food, fulfilling the needs of the population, and sustaining environmental flows. The aim of the game is to provide an opportunity to practice how different water management policies can lead to the sustainable development of society in harmony with Nature.

Blog // What can Transdisciplinarity give back to Communities?

This article presents a research project conducted by the STEPS Centre, using the WEFE Nexus as a conceptual tool for transdisciplinary engagement through urban gardening in the peripheral area Novo Recreio in north Guarulhos, part of the Metropolitan Region of São Paulo, Brazil. It shows the notion of the WEFE Nexus has the potential to bring people together across different siloes, organisations, identities, institutions, levels and sectors. But could it contribute to wider struggles against...
