To the question of agricultural water supply

Abstract

Regions in the south of the European territory of Russia and Western Siberia are experiencing water scarcity. The lack of water resources takes place against the background of a decrease in total water use in the country’s economy and in irrigation. It is necessary to reduce unproductive water losses, improve irrigation and drainage systems and irrigation technologies. This will positively affect diffuse pollution and the ecological state of water bodies draining agricultural land. It is possible to expand the use of groundwater in conjunction with surface water for drinking water supply and irrigation. Requires consideration of the problem of territorial redistribution of river flow. It is necessary to review the main provisions of the organization of water management and create a unified water management structure for efficient water use in agriculture.
