Management and development

The water in the Niger River basin is partially regulated through dams. In Mali the Sélingué Dam on the Sankarani River is mainly used for hydropower but also permits irrigation. Two diversion dams, one at Sotuba just downstream of Bamako, and one at Markala, just downstream of Ségou, are used to irrigate about 54,000 hectares. In Nigeria the Kainji Dam, Shiroro Dam, Zungeru Dam, and Jebba Dam are used to generate hydropower.

The water resources of the Niger River are under pressure because of increased water abstraction for irrigation. The construction of dams for hydropower generation is underway or envisaged in order to alleviate chronic power shortages in the countries of the Niger basin. The FAO estimates the irrigation potential of all countries in the Niger river basin at 2.8 million hectares. Only 0.93m hectares (ha) were under irrigation in the late 1980s. The irrigation potential was estimated at 1.68m ha in Nigeria 0.56m ha in Mali, and the actual irrigated area was 0.67m ha and 0.19m ha.
