Treadle pump (TP) technology has been promoted by Enterprise Works Worldwide (EWW) as an alternative to the traditional rope and bucket irrigation that is necessary to overcome the challenge of uncertain and inadequate rainfall for agricultural production. The aim is to improve output, increase incomes and reduce poverty among farm households. This study examines the strategies used for dissemination of the TP and the dynamics of its adoption and impacts, with a special focus on poverty reduction. The results of the study reveal that time and labor savings for irrigation, increased size of irrigated areas and lack of fuel requirements are the attractive features of the TP for those who adopt it. Adoption of TP increases land and labor productivities; and also net farm incomes. The study also demonstrates that adoption of the TP reduces poverty.
