The Challenge Program on Water and Food (CPWF) in the Volta Basin
The Volta basin lies predominantly in Ghana and Burkina Faso, with small areas in Benin, Côte d’Ivoire, Mali and Togo. These countries rank amongst the poorest in the world. The basin is inhabited by 19 million people, 70 per cent of whom are rural. Economies are reliant on agriculture, mostly rainfed crossing four agro-ecological zones, with rainfall varying between 500-1100 mm/year. Highly variable rainfall during the growing season presents problems of short season droughts, even where total rainfall appears adequate. Less than 10 per cent of the average total rainfall ends up in the river, making river discharge, and those who depend on it, highly sensitive to variations in annual rainfall.Yields—and hence water productivity—are low; often 10 per cent or less of potential.
Improving rainwater management has the potential to reduce the vulnerability of the poor. A large number of small reservoirs have been developed dotting the northern Ghanaian and Burkinabe landscapes. These reservoirs serve multiple purposes including domestic water supply (mainly for washing), livestock, small scale irrigation, and limited aquaculture. The reservoirs are common property resources which help communities to buffer themselves against intense dry seasons but often fail due to poor institutional and technical mechanisms required to build, maintain and sustain them for optimal socially equitable benefits.The CPWF research in the basin (2010 -2013) will explore the institutional and technical aspects of small reservoir development and maintenance, embedded within a wider rainwater management system for the Volta River Basin.
