Small-scale private irrigation (SPRI) schemes make up most of the irrigated area in Nigeria, although they constitute only about three percent of the cultivated area in the country. Farmers’ demand for SPRI is potentially affected by diverse sets of agroecological, socioeconomic and risk factors. While the constraints on SPRI expansion have been well investigated by many studies in Nigeria, key knowledge gaps in at least four areas, still need to be resolved. These gaps are: (1) lack of knowledge of water sources; (2) perceptions of risks associated with rainfall and access to good quality water; (3) transaction costs associated with investments in irrigation; and (4) effectiveness of public institutions activities in SPRI.
