The publication characterizes the current water security of irrigated agriculture in the Republic of Crimea and the prospects for its development for the period up to 2030. The object of research is the water supply of the Crimean peninsula, the subject is the shortage of water resources for irrigated agriculture in the Republic. A low level of provision of the Crimean peninsula with its own fresh water for supplying the population, industry and agriculture, due to the natural and climatic features of the region, has been established. Approaches to solving the problem of water supply in the region in retrospect, based on water supply by the North Crimean Canal, are presented. A significant, up to 95%, reduction in the irrigated lands used for their intended purpose, associated with the termination of the water supply of the Dnieper water, limits the possibilities of the republic's agricultural production in solving the problems of food security and import substitution. Based on the materials of the draft Scheme for the Integrated Use and Provision of Water Resources of the Republic of Crimea, a modern solution for providing irrigation water to the agrarians of the Republic of Crimea at the expense of their own resources without involving external water sources until 2030 is shown. years for which the probability of normative precipitation does not exceed 5%. It is proposed to start the solution of the problem of water security of the agricultural production of the republic with the formation of a rational system of water use and water conservation, regardless of the possible elimination of the shortage of irrigation water by the renewed water supply of the North Crimean Canal. The successful formation and development of rational water use and water conservation in irrigated agriculture will be facilitated by scientific substantiation and support of comprehensive measures to eliminate the shortage of water resources in Crimea.
