abstract = "{The Upper Ganga Basin (UGB) in Uttar Pradesh, one of the most populous
regions in India, has experienced a continuous decline in
groundwater levels over recent decades. On the basis of in situ
observations, simulations show that the western part of Uttar
Pradesh and several districts of southern Uttarakhand (covering
an area of \raisebox{-0.5ex}\textasciitilde 150,229 km$^{2}$)
has lost an estimated 62 km$^{3}$ of groundwater during
2005-2023, which is five times the storage capacity of India's
largest reservoir. GRACE satellite-derived estimates of
groundwater storage change also corroborate with the estimated
rate of groundwater decline featuring a correlation coefficient
of 0.8 with in situ data. The present study reveals that
frequent droughts in the area have reduced natural recharge from
rainfall and increased groundwater abstraction. Groundwater
abstraction from confined aquifers contributes towards
\raisebox{-0.5ex}\textasciitilde 42\% of the total groundwater
abstraction, which has increased over time as the number of deep
tube wells has surged exponentially. To mitigate such a
predicament, urgent action is required for sustainable
management of groundwater, which can be achieved by changing
agricultural practices (such as crop rotation), rejuvenating
surface water bodies, developing managed aquifer recharge sites
and adopting appropriate water use and management policies
across local to state levels.}",
