Abstract
Ecological safety has become one of the most critical factors in regional development. This article examines how environmental methodologies can be integrated and effectively applied at the regional level in Russia and Kazakhstan—two countries whose unique natural resource potentials contribute significantly to global sustainable development. The study systematizes and compares data from both countries across national, regional, and local frameworks, identifying key priorities, directions, and specific mechanisms for applying ecological policies in their regions. Additionally, it shows how national priorities align with those identified in regional environmental policies. This article brings together environmental methods for assessing, monitoring, and managing regional ecosystems in Russia and Kazakhstan. The main focus is made on understanding ecosystem connections, predicting changes, and developing strategies for sustainable regional development. By comparing the application of these methods and policy priorities at national and regional levels, the study highlights practical challenges in implementing current frameworks. Key elements include environmental impact assessment, ecological monitoring, and resource management. The proposed approach offers a comprehensive yet flexible way to address regional environmental issues, balancing economic growth with nature conservation. The methodologies and criteria presented can help establish a rigorous framework for systematic assessment and management of environmental impacts, supporting evidence-based decisions that balance environmental concerns with sustainable development. In conclusion, the article summarizes best practices and suggests improvements to ecological policies in Russia and Kazakhstan, pointing out opportunities to enhance ecological resilience amid global environmental change.
