ECOLOGICAL ASSESSMENT OF MILITARY ACTIONS IMPACT ON THE KYIV REGION HYDRONETWORK AND STRATEGIES FOR AQUATIC ECOSYSTEM RESTORATION

The article examines the complex ecological impact of military actions on the aquatic ecosystems of the Kyiv region during the Russian-Ukrainian war.Based on comprehensive analysis of scientific literature and satellite imagery, the research identifies patterns of destructive influence on regional hydronetworks.A bibliometric analysis of research trends revealed four main clusters of scientific focus: physico-chemical aspects of water pollution, environmental monitoring methodologies, biological responses to military stressors, and specific chemical contaminants.The spatial analysis of satellite data enabled mapping various types of damage to water ecosystems in the Kyiv region, including destruction of hydraulic structures, pollution of watercourses from intensive fighting and fires, damage to water supply infrastructure, and mass mortality of aquatic organisms.The northern areas of the region experienced the most severe impacts due to the highest intensity of combat operations.The research identifies systemic patterns of ecosystem degradation, including chemical pollution from military equipment and ammunition, physical destruction of habitats, alteration of hydrological regimes due to damaged infrastructure, and disruption of ecological connectivity.The article proposes a classification of destructive impacts (chemical, physical, mechanical, biological) and corresponding strategies for ecological rehabilitation, considering the specifics of damage type, effectiveness of remediation methods, and implementation timeframes.This systematic approach provides a methodological foundation for developing regional programs of post-war ecological restoration of damaged hydroecosystems in the Kyiv region.Purpose.To conduct a comprehensive ecological assessment of the impact of military actions on the state and functioning of the Kyiv region hydronetwork and develop a classification of destructive impacts to form a methodological basis for the restoration of damaged aquatic ecosystems.Method.The research employed spatial analysis of satellite data, bibliometric analysis of scientific publications, cartographic modeling of military impacts, and systematic analysis of destructive influences on regional water ecosystems of the Kyiv region.Results.A detailed mapping of war consequences in the Kyiv region revealed significant disruptions to the hydronetwork, including the destruction of hydraulic structures, pollution of watercourses, damage to water supply infrastructure, and mass mortality of aquatic organisms, with northern areas experiencing the most severe impacts due to intensive combat operations.Scientific novelty.For the first time, a comprehensive ecological assessment of military impacts on the Kyiv region hydronetwork has been conducted, resulting in a systematic classification of destructive influences on aquatic ecosystems and corresponding rehabilitation strategies.Practical importance.The proposed classification of destructive impacts and rehabilitation strategies provides a methodological foundation for developing regional programs for ecological restoration of war-damaged hydroecosystems in the Kyiv region and can guide environmental authorities in post-war recovery planning.
