Application of advanced computer technologies in determination of irrigation regimes for cotton in water scarcity areas

Agriculture is one of climate change's most sensitive economic sectors. In Uzbekistan, 95% agricultural products come from irrigated lands. Because the sector Uzbekistan meets population's demand for food and industrial raw materials, ensuring national security. Different climatic soil-hydrogeological variations are countrywide significant to assess possible increase in crop water determine consumption irrigation regime Therefore, this research aimed create hydrological module-zoning (HMZ) map lands using geoinformation systems (GIS) technologies by employing spatial data determining regimes cotton according FAO methodology. The area investigation was northern regions Republic Karakalpakstan, located which has undergone change over last 30 years due Aral Sea tragedy faced with scarcity. HMZ study been figured out ArcGIS 10.8 program based on Bespalov's Determining developed HMZs CropWat 8.0 meteorological parameters. showed that identified areas Bespolov 80s century have significantly changed because change.
