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for more than two thirds of irrigated area in the world, much of it still gravity-fed; about 85 percent of all water withdrawn in the region is used for irrigated agriculture.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

Nexus Modelling // Towards Ranking the Water–Energy–Food–Land Use–Climate Nexus Interlinkages for Building a Nexus Conceptual Model with a Heuristic Algorithm

By Chrysi S. Laspidou, Nikolaos Mellios and Dimitris Kofinas. In this article, a practical heuristic approach for gaining a systemic and contextual perspective on nexus component interlinkages is presented, by building on a simple three-point typology of interactions. The approach is simple and can be applied in any case study a nexus analysis is pursued, regardless of data availability.

A Nexus for Basin Organisations in the Sahel // Multisectoral comparison: OMVS - LCBC - NBA

By Luca Ferrini (Project Manager, Nexus Regional Dialogue Programme Niger Basin) and Lucia Benavides. This article provides a comparative analysis about the level of integration of different sectors within the mission statements of three River Basin Organisations in the Sahel: the Senegal River Basin Development Authority (OMVS by its French acronym), the Lake Chad Basin Commission (LCBC) and the Niger Basin Authority (NBA). It further stresses different focus areas of the mission statements,...
