Groundwater, a renewable and finite natural resource, is a vital source of sustenance for humans and different ecosystems in the semi-arid regions. Rapid population growth in the last three decades has caused a rise in water demand which has inadvertently posed a stress on its availability. The paper ‘Hydrogeological delineation of groundwater vulnerability to droughts in semi arid areas of western Ahmednagar district’ (https://bit.ly/2wzX1EZ) attempts to provide a robust methodology to prioritize areas vulnerable to groundwater availability. It is based on the study involving a field hydrogeological mapping that was integrated with remote sensing and GIS to delineate areas. The research brief ‘How much water is in the ground, and what does this mean for vulnerability?’ summarises the key findings of the paper.
