This paper (PDF) by the International Water Management Institute (IWMI) reviews the evidence available on the provision of financing for African smallholder farmers to purchase irrigation equipment such as pumps, pipes and drip irrigation systems. It sets the scene by first reviewing the literature on experiences with providing microcredit and other microfinance services as a poverty reduction strategy. Based on both case studies and several systematic reviews of the literature, it finds that the outcomes and impacts on poverty, gender equity and broader economic development are mixed at best. Microcredit is not a silver bullet solution to poverty, but it can often help poor households improve their lives. The paper then reviews the demand for and supply of financing for smallholders to purchase irrigation equipment. In surveys, farmers express a strong demand for equipment such as pumps, but often point to the lack of affordable and appropriately designed credit as a critical impediment to gaining access to such equipment.
