Abstract
Small-scale irrigation can significantly increase household agriculturalrevenues. We explore the extent towhich these earnings vary based on the share of farmersirrigating nearby. Using primary data collected from 985 smallholderfarmersin rural Ethiopia,we demonstrate that irrigating in villageswith high irrigation prevalence is associatedwith greater agriculturalrevenues and more commercialization opportunities, particularly in the dry season. The revenue gains associatedwith high-prevalence irrigatorslargely accrue to thosewho use mechanized irrigation technologies. Supporting low-prevalence irrigatorswith policiesthat improve market access can greatly amplify their ability to generate financialreturns.
