Smallholder farmers in sub-Saharan Africa and South Asia are increasingly using small-scale irrigation to cultivate their land. Individually owned and operated irrigation technologies improve yields, reduce risks associated with climate variability and increase incomes, allowing farmers to purchase food, health care and education. There is great potential for many more farmers to benefit from small-scale irrigation. This report presents governments, donors, lending institutions, the private sector and farmers with the opportunity to make well-informed decisions about investments in agricultural water management (AWM) that could change the lives of millions of rural people.
