Sudan

NOTE: This study was conducted prior to the Sudan and South Sudan split, therefore there is only one sub-national irrigation areas report, referring to pre-2011 Sudan.

Area equipped for irrigation is 1 863 000 ha [SD01]. The figures refer to year 2000. The irrigated area is visible in the table below and also can be downloaded as Sudan irrigation areas in PDF or Sudan irrigation areas in Excel.No sub-national statistics on areas equipped for irrigation were available.

Irrigated areas were derived from the AFRICOVER land cover data base [SD02]. However, it was found that several large irrigation schemes were not detected as irrigated by the land cover classification (e.g. Gash Delta, Tokar Delta, Aweil). Others were found to be incomplete. Therefore the missing schemes were derived from the FAO irrigation map for Africa [SD03] or digitized from another irrigation map [SD04]. The shapes of the boundaries of the digitized irrigation areas were improved by using satellite imagery [SD05].

Area actually irrigated was 800 000 ha in year 2000. 4 percent of the equipped area in full/partial control schemes (69 239 ha) was irrigated with groundwater in year 1995 while surface water sources were used in the remaining part [SD01].
