abstract = "{Groundwater resources in Debre Markos, Ethiopia, are under increasing
pressure from urbanization, agricultural expansion, and climate
change. This study integrates GRACE satellite data (2002─2017)
and GIS-based land use/land cover (LULC) analysis to assess
groundwater storage variations, identify contamination risks,
and propose sustainable water supply strategies. Results show a
persistent decline in groundwater storage and yield, especially
in wells surrounded by high-risk land uses. Buffer zone analysis
revealed substantial encroachment by agriculture and built-up
areas within 300 m protection zones. A spatial buffer analyses
around wells in the Wutren and Sentera fields reveal,
significant overlap in drawdown zones and inadequate well
spacing some as close as 16 m leading to increased mutual
interference and aquifer stress. Moreover, risk zones,
delineated based on land use encroachment and proximity-based
interference, highlight critical areas where agriculture and
built-up zones compromise source protection. The study
recommends enforcing groundwater protection buffers, optimizing
well spacing, regulating land use within critical zones, and
expanding remote sensing tools for continuous groundwater
monitoring and sustainable water supply planning.}",
