Global Map of Irrigation Areas

Guinea

The area equipped for irrigation is 94 914 ha [GN01]. The figures refer to year 2001. Irrigated area per basin is documented in the table below.

The location and command area for 13 irrigation schemes was derived from the FAO-map of irrigated areas in Africa [GN02]. The total irrigated area in these schemes is summing up to 6870 ha. The remaining irrigated area was distributed according to the GLC2000 land cover map for Africa [GN03] to areas classified as "Mangrove", "Irrigated cropland", "Mosaic of cropland and woody vegetation" or "Mosaic of forest and cropland". First it was made sure that 50 850 ha irrigated area was assigned to areas classified as "Mangrove" (see [GN01]). After area equipped for irrigation was assigned also to the other land cover types beginning with "Irrigated cropland", then " Mosaic of cropland and woody vegetation" and finally if necessary also to areas classified as "Mosaic of forest and cropland" with the lowest priority.
