This study investigates the process of building a stable methodological basis for assessing environmental risks in regions. The possibilities of using integrated indicators of environmental risks have been considered, which are a useful tool for summarizing complex information. However, their interpretation should be especially cautious during periods of social upheaval. The combination of a quantitative index with a qualitative analysis is necessary for a complete and adequate assessment of environmental safety for such periods.
This work analyzes the methodological robustness of composite indices of environmental safety of regions under war-time conditions using Ukraine as an example. The influence of the choice of normalization methods, weighting schemes, and processing of missing data on the results of integrated ranking was studied. It is shown that under crisis conditions the semantics of key social-ecological indicators undergoes qualitative changes, as a result of which conventional interpretations of their dynamics become incorrect.
A comparative analysis of combinations of normalization and weighting of indicators for calculating the integrated index of environmental safety of regions in Ukraine over 2021–2022 was conducted. It was found that the rank approach in combination with equilibrium weighting is methodologically unstable under crisis conditions and leads to inversions in regional ranking. An algorithm for calculating the index has been proposed, which involves checking the stability of regional indicators for the completeness and reliability of statistical data, which increases the adequacy of environmental risk assessment during the conflict period. This is particularly important for Ukraine but is also relevant for other countries experiencing or recovering from conflict.
The findings make it possible to increase the readiness of an environmental monitoring system for emergencies, as well as contribute to the construction of a robust methodological base for assessing environmental risks.
