小农灌溉正在成为撒哈拉以南非洲的一个发展优先事项。本文根据对9个国家1554个小农户的调查，将传统农业与自流灌溉、人工扬水灌溉和机动抽水灌溉进行了比较。机动泵灌溉农民报告的每英亩土地和每个家庭工人的净增加值最高，重力流和人工灌溉农民的收入略高于只靠雨水灌溉的农民。除了使负担得起的水泵更容易获得外，改善流动资本的供应、加强土地保有权的保障和确保负担得起的燃料的供应，都有可能加快撒哈拉以南非洲小农灌溉的发展。
Smallholder irrigation is emerging as a development priority in Sub-Saharan Africa. Based on a survey of 1554 smallholders from nine countries, this paper compares rainfed farming with gravity-flow, manual-lift and motor-pump irrigation. Motor-pump-irrigation farmers reported the highest net value added per acre and per family worker, with gravity-flow and manual-irrigation farmers earning marginally more than rainfed-only farmers. In addition to making affordable pumps more readily available, improving the availability of working capital, enhancing security of tenure and ensuring the availability of affordable fuel are all likely to accelerate smallholder irrigation development in Sub-Saharan Africa.
