This work falls under the ERC funded project- A Global Assessment of the Limits of Groundwater Use (GEOWAT). During this project, we aim to determine the physical limits of groundwater withdrawal by providing the first global estimates of fresh groundwater availability - subject to past and future human water use. A high resolution version of PCR-GLOBWB will be used to yield the locations of, and the times when, physical limits of fresh groundwater use will be reached. In addition, we will evaluate how technological strategies may increase the volume of extractable fresh groundwater and promote water table recovery.
