Fig. 1: Changes in rates of GW withdrawals between No GWC and GWC across regions, projected to 2050.
From: Ending groundwater overdraft without affecting food security
No GWC is the baseline without GW conservation, while GWC ensures that GW withdrawals are equal to net recharge rates. Both are simulated under climate change, averaging results from three climate change scenarios: GFDL, HadGEM and IPSL with RCP 8.5. Calculated using the IMPACT-IWSM.
