Global Map of Irrigation Areas

Burundi

Area equipped for irrigation in Burundi is 21 430 ha [BI01]. The figures refer to the year 2000. No recent sub-national statistics on irrigated area have been available.

Irrigated area was assigned to specific grid cells by combining a database of irrigation projects in Africa [BI02], information on irrigated area per district representing the situation in year 1985 [BI03], indicative information on the location of irrigated areas as published in the AQUASTAT country profile [BI01], land cover information provided by the AFRICOVER project [BI04] and a map of micro-dams used in irrigation projects [BI05]. AFRICOVER lists two polygones of irrigated land cover type in the eastern part of the country. One was classified as irrigated sugar cane and the other one as irrigated herbaceous. 160 ha irrigated rice and 1450 ha irrigated sugar cane have been reported for the eastern part of the country [BI01]. Therefore these areas were assigned to the polygones derived from AFRICOVER. 2800 ha of irrigated land were assigned to 28 locations indicated on the map of micro-dams used for irrigation [BI05]. Information in the AQUASTAT country profile and the 1985-district data indicate that there exists much irrigation in l’Imbo plain (districts of Gihanga, Mpanda and Mutimbuzi). Irrigated area was thus distributed to areas in that region covered by herbaceous crops [BI04]. Additionally the FAO-irrigation project database lists some very large projects in upland areas adjacent to the l’Imbo plain. These projects are assumed to represent rice cultivation and irrigated areas was distributed to herbaceous crop areas [BI04] surrounding these projects
