The territory of the Republic of Kalmykia belongs to the driest regions of Russia. Systematically recurring droughts cause the death of vegetation of natural pastures and agricultural crops, the conditions for watering the territory are worsening, which contributes to an acute shortage of water supply for the rural population and livestock. To withstand negative weather and climatic phenomena and intense anthropogenic pressure in conditions of increasing aridization, the sustainable operation and development of the reclamation and water management complex and improved management of land and water resources are necessary. The purpose of the research is to develop a digital database of the Chernozemelskaya watering and irrigation system of the Republic of Kalmykia for information and technological support for decision-making on the selection of the necessary set of measures for the rational use of water and land resources. The research methodology consisted of several stages: the development of the structure of the GIS project of the Chernozemelskaya watering and irrigation system, including coordination of system objects and localization, mineralization and chemical composition of water, technical condition of hydraulic structures, soil and reclamation condition of irrigated lands, pasture and estuarine agroecosystems. The source of the digital databases was long-term indicators of comprehensive environmental monitoring, inventory data of reclamation on-farm irrigation networks, information from the portal of the Federal State Budgetary Scientific Research Institute “Raduga”, topographic maps, a public cadastral map and satellite images. The developed GIS project of the Chernozemelskaya watering and irrigation system will make it possible to quickly make decisions on the selection of the necessary set of measures and rational use of water resources.
