Economic Analysis of Benefits and Costs: Multiple Uses Water Services Project supported by the Challenge Programme on Water and Food por Jumbe, C.B.L., Chinangwa, S.M.J.

“…The analysis of benefits and costs in this report was meant to build on the Winrock study whose analysis centered on the incremental benefits, poverty impacts and costs of multiple use approaches relative to single use approaches. While the Winrock study provided useful and important information and guided the identification of benefits and costs of the MUS Project, the analysis in this report also uses the technical approach for evaluating research and advocay projects. …”
