Annotatsiya

Global climate change has increased the frequency and severity of drought events, reducing water availability in arid regions. In Uzbekistan, more than 80% of agricultural production depends on irrigation; accurate estimation of crop water demand is therefore critical for food security and sustainable resource management [1, 5]. Crop water consumption was estimated using the Kostyakov empirical formula (E = K·Y) and the bioclimatic Alpatyev equation (E = Kb·Σd) [5, 9]. Seasonal irrigation norms were determined from the Kostyakov water balance equation [5]. Regional bioclimatic coefficients (Kb) were compiled for all provinces of Uzbekistan based on Xamidov et al. [2, 3]. A web-based GIS calculator was built with Leaflet.js and Turf.js. Validation on a 13.75 ha polygon in Khorezm region (cotton + wheat, K = 1.20) yielded an estimated annual demand of 189.8 thousand m³, consistent with normative values [2, 5]. The developed GIS model enables rapid, spatially explicit estimation of irrigation water demand and provides an effective tool for drought monitoring and irrigation planning.
