An attempt is made to assess in general terms the potential for utilizing the region's wind resources for pumping water. While very few areas receive winds that are both strong and reliable enough to be called high potential areas, it is nevertheless possible to identify a considerable number of areas as having medium potential. A further positive factor is that in many areas the wind tends to be strongest in the dry season when most water is required. Minimum requirements for the utilization of wind power are suggested in relation to water supply and irrigation needs. The costs of systems using locally made wind pumps are compared with those using imported diesel pump units. It is argued that for small water schemes, the windmill is generally to be preferred on the basis of lower maintenance cost and potentially greater reliability. An important feature of the windmill is its comparative simplicity, which enables maintenance and repairs to be performed by local personnel. In social terms, it is claimed that this is an advantage since it encourages greater local involvement and responsibility.
