Sign inCOLORADO STATE UNIVERSITY. DEPT. OF ECONOMICS
Existing ex-post cost-benefit analyses of irrigation projects in the Sahel are reviewed.
Sparling, Edward W. · 1970

Abstract
The main lesson taught by the analyses is that decentralized and participatory small-scale irrigation of rice is a sound investment in the Sahel, whereas highly centralized, large-scale irrigation of rice is not. Policy recommendations reflecting these conclusions are provided. The need for additional cost-benefit data on large-scale, indivisible water diversion or impoundment facilities is noted.
