Global Map of Irrigation Areas

Chad

Area equipped for irrigation was reported to be 30 273 ha [TD01]. The figures refer to year 2002. Irrigated area per region is documented in the table below.

Irrigated area was distributed first to 6 large-scale schemes. The position and command area (in total 10 050 ha) of the schemes was taken from the FAO irrigation project database for Africa [TD02]. The remaining part of the irrigated area was assigned to zones of traditional or private irrigation and to palm groves as digitized from an irrigation map [TD03]. The outlines of the large scale schemes and of the digitized irrigation zones were adjusted using satellite imagery [TD04].
