From Torrents to Trickles: Irrigation's Future in Africa and Asia

Claudia Ringler

Annual Review of Resource Economics, 2021, vol. 13, issue 1, 157-176

Abstract: Irrigation has been a key component of agricultural intensification and transformation in Asia and has the potential to take on the same role in Sub-Saharan Africa. Irrigation has contributed to increased food production, lower food prices, higher rural employment, and overall agricultural and economic growth. At the same time, irrigation--through its large consumptive water use--has accelerated water depletion, degradation, and pollution; moreover, it has benefitted richer farmers more than poorer farmers. This article reviews the contributions and challenges of irrigation and identifies a series of measures to increase the sustainability and equity of irrigation going forward.
