Groundwater Irrigation: Actual and Potential
(a) Actual area irrigated with groundwater in 2005 expressed in ha. per cell adapted from Siebert et al. (2010) and (b) groundwater irrigation potential for the year 2000 expressed as
the percentage of the area irrigated with groundwater in 2005Source: Altchenko, Y.; Villholth, K.G. 2015. Mapping irrigation potential from renewable groundwater in Africa – a quantitative hydrologicalapproach. Hydrology and Earth System Sciences 19(2): 1055-1067.
