Is it possible to move to a regime of sustainable groundwater extraction while still meeting food demand growth? Rosegrant et al. (2002) assess the impact of phasing out unsustainable groundwater overdraft by 2025 in a low groundwater pumping scenario (LGW). 0. 55 at the basin or country level (Rosegrant et al. 2002). 1. Globally, under the LGW scenario, irrigated cereal production would decline by 3%. This decline would be partially compensated by an increase in rainfed cereal production. Groundwater extraction under the LGW scenario would fall to 753 km3 by 2025 compared to 922 km3 under the baseline scenario, and 817 km3 in 1995 (Rosegrant et al.
