Seasonal changes in groundwater levels and salinity were investigated in the irrigated lands of Angor district, Uzbekistan from 2018 to 2023. Using field data from 129 wells and GIS-based interpolation, the study found a generally stable water table (mean depths of 2.28 m in April, 2.29 m in July, 2.23 m in October), but a significant increase in groundwater mineralization from 1.65 g/L in April to 2.04 g/L in October. This rise in salinity after the growing season indicates growing soil salinization risk. Spatial analysis revealed higher salinity near desert margins and in areas of intensive irrigation, highlighting key drivers of degradation. The results suggest current irrigation practices in Angor are unsustainable. To ensure long-term agricultural viability, improved land and water management strategies are urgently needed.
