Fig. 7. Equilibrium states of water-table depth for different combinations of vegetation cover, including current levels of groundwater pumping. Avoiding water tables reaching the surface equilibrium condition will require a trajectory of revegetation something like that depicted, in combination with continued pumping. A reduction in average rainfall (over a prolonged period) would alter this picture. (After Anderies et al. 2006). Erratum (added 31 March 2009)
