The Sri Lankan based International Water Management Institute (IWMI) has produced this report assessing the need and effectiveness of agricultural water storage (AWS) in Africa, in the context of climate change risks.

This Working Paper summarizes research conducted as part of the AgWater Solutions Project in Burkina Faso between 2009 and 2012. Researchers from the AgWater Solutions Project examined the potential for small reservoirs, inland valley cultivation and the use of motorized pumps. The main findings indicate that (1) Small reservoirs need better management at all stages to reduce costs and improve equity.Costs could be comparable with other AWM options. The total investment to reach 50% of the potential demand in Burkina Faso could be as much as USD 1,136 million.
This paper reports on a form of multi-criteria analysis that provides a formal approach for evaluating the suitability of a wetland for specific agricultural uses, and ensures that explicit consideration is given to the possible consequences of such utilization. The method is based on a hybrid of ideas taken from concepts and methodologies related to: environmental flow assessments, land suitability classification and the hazard evaluation procedures used in the design of dams.
