Abstract
The paper outlines the main directions and features of bilateral cooperation between the UN and Kazakhstan in the field of environmental security, focusing on the signed legal acts. Based on the analysis of official sources, as well as domestic and foreign literature, joint projects and initiatives in the field of environmental cooperation have been considered. Problems and challenges faced by bilateral relations between the UN and Kazakhstan at the present stage, such as financing, low institutional capacity, the problem of introducing new technologies, and others, are considered. This allows for giving recommendations for solving problems in these aspects. The analysis of cooperation between the United Nations and the Republic of Kazakhstan in the field of environmental security allowed us to get a full picture of its impact on environmental security and the sustainable development of the Republic. The practical significance of this study lies in the possibility of its results being utilized by state authorities in the development of new environmental programs. The conclusions formulated in the paper contribute to a deeper scientific understanding of the role of international organizations in addressing regional environmental problems.
