abstract = "{Haryana, situated in northern India, experiences a semi-arid to arid
climate and faces significant challenges related to groundwater
depletion (GWD). The state's agricultural sector, heavily
reliant on groundwater for irrigation, contributes significantly
to its over-exploitation, further exacerbating the issue of
groundwater. Geospatial techniques have emerged as powerful
tools for monitoring and analysing groundwater storage (GWS)
variations in spatial and temporal domains. Satellite data,
particularly from the gravity recovery and climate experiment
(GRACE), provides valuable insights into terrestrial water
storage (TWS) and its components, including groundwater. In this
study, GRACE RL06 data and global land data assimilation system
(GLDAS) and Noah land surface model were utilized to evaluate
the spatial and temporal variations in GWS across Haryana from
2003 to 2023. The results were validated using ground-based data
from the central ground water board (CGWB) to ensure accuracy.
The study reveals that, there has been a consistent decline in
GWS across Haryana, with some areas experiencing drops of over
200 mm in GWS. In particular, the southern parts of Haryana,
where agricultural water use is particularly high, showed the
most significant declines in GWS. The analysis of TWS reveals a
significant decline in GWS, with an average annual depletion of
12 mm per year. Seasonal variations were found to be prominent,
with the most substantial declines occurring during the winter
and spring months. The average GWD was found to be approximately
11.3 mm per year in Haryana. The spatial distribution maps of
GWS further emphasize the depletion in key agricultural
districts such as Mahendragarh and Kurukshetra, where the rate
of groundwater extraction exceeds the rate of recharge.}",
