Quantifying Water Consumption through the Satellite Estimation of Land Use/Land Cover and Groundwater Storage Changes in a Hyper-Arid Region of Egypt

One of the areas that show most visible effects human-induced land alterations is also world’s essential resource: water. Decision-makers in arid regions face considerable difficulties providing and maintaining sustainable water resource management. However, developing appropriate straightforward approaches for quantifying use arid/hyper-arid still a formidable challenge. Meanwhile, better knowledge cover (LULC) changes on natural resources environmental systems required. The purpose this study was to quantify consumption hyper-arid region (New Valley, Egypt) using two different approaches—LULC based optical remote sensing data groundwater storage Gravity Recovery Climate Experiment (GRACE) satellite data—and compare contrast quantitative results approaches. LULC area constructed from 1986 2021 identify investigate primary patterns. analysis utilized GRACE mascon solutions 2002 New Valley. showed an increase agricultural Valley’s oases. They increased irrigation usage continuous decrease overall Valley domestic calculated as 18.62 km3 (0.93 km3/yr) estimates. Moreover, were extracted be 19.36 ± 7.96 (0.97 0.39 km3/yr). indicated consistent with depletion by applying GRACE. This provides reference regional sustainability management regions.
