Abstract
The article discusses the problems of water resources, as well as various ways to solve these problems. The ecological, economic, social and political aspects are considered of the growing global water crisis and the possibilities of the Republic of Kazakhstan when solving the problems of water scarcity. International and national water management were analysed. The methodology is developed and the procedures for coordinating water use strategies are proposed in conditions of uncertainty and the corresponding complexes of mathematical models, in which, along with the volumes of water resources actually received by water users, there are approximate values of virtual resources (“guaranteed” volumes). Coordination is presented of water use strategies in hierarchical structures and systems using transboundary water bodies. The substantiation is given of long-term strategies of water use and planning of water protection measures, as well as strategies for managing the joint use of surface and underground water. Approaches were developed to form water use and sanitation markets. The methodological foundations of the formation of natural rent and the stability of the functioning of water management systems are studied.
