Abstract
The article analyzes the impact of water scarcity on agricultural production, food supply, price stability, and the economic accessibility of food for the population. The study applies economic analysis, functional modeling, statistical description and comparative analysis methods. Proposals are substantiated for improving water use efficiency, economically stimulating water-saving technologies, introducing results-based subsidies, using indicators of water productivity (WP) and the economic return of 1 m³ of water (EW), as well as a digital early warning system for water-food risks. A territorial food risk index Rₑₒ is proposed, along with an approach to classifying territories into green, yellow, and red risk zones. The calculation example shows that applying a water-saving technology increases water productivity from 0.67 to 0.93 kg/m³, i.e. by 38.8%. The results justify the need to integrate the economic assessment of water resources with food security policy.
