Abstract
The article analyzes the problems and prospects of introducing the ecosystem approach to water resources management in Kazakhstan. The significance of water resources for sustainable economic, social and ecological development is substantiated, as well as the necessity of applying the ecosystem approach under conditions of water resources scarcity. The research methods used, including the analysis of official reports, statistical data and scientific literature, are described. The results of the study identify key problems of the existing water resources management system, such as the lack of standardized methodologies and insufficient integration of local knowledge and experience. Recommendations for adapting successful international experience and developing effective legal and institutional mechanisms in Kazakhstan are presented. It is concluded that it is necessary to apply the ecosystem approach to ensure water security and improve the condition of aquatic ecosystems, which contributes to achieving sustainable development in the region.
