ECONOMIC AND ENVIRONMENTAL APPROACHES TO THE DEVELOPMENT OF INTEGRATED WATER RESOURCES MANAGEMENT SYSTEMS IN A ZONE OF INSUFFICIENT MOISTURE

This study is devoted to the study of economic and environmental approaches to the development of an integrated water resources management system using the example of one reservoir located in the zone of insufficient moisture in the Northern Black Sea region of Ukraine. To create an integrated and sustainable management system for the basin's water resources and assess individual components of the water balance, methodological, statistical, economic, and environmental approaches were used. The study area, like the entire south of Ukraine in general, belongs to the zone of insufficient moisture. The region is characterized by an increase in turbulent heat exchange between the underlying surface and the atmosphere up to 5,80 kcal/cm2 , which in turn causes a sharp increase in unproductive resource losses. Taking into account the characteristics of the study area, the specifics of the development of its economic system and the recreational importance of the water body, the work presents the basic requirements for the development of an integrated water resources management system, which are based on the “basin principle” of constructing a management system, the horizontal and vertical hierarchy of the economic system of the basin, and the use of methodology “climate and reserve” models when assessing the resource capabilities of a territory, public participation in the management, financing, planning and development of water infrastructure, as well as the priority use of an ecosystem approach in the implementation of a scheme for integrated management of water resources in the region. The results show that the development of an integrated water resources management system should be based on an overall calculation of all components of natural and artificial recuperators, which allows water resources to be balanced and a rational management system to be developed. It should also be noted that integrated water resource management systems in the risky farming zone, together with the development of an integrated system for the sustainable use of an extremely scarce resource, should, first of all, prevent precedents of unproductive water losses.
