The object of study was the decline of global water resources in the context of global climate change. This study examines the quantitative and qualitative degradation of water systems and the growing challenges of accessibility for populations worldwide. The analysis highlights the distructive consequences of global warming on ecosystem contamination and all the related issues such as altered precipitation patterns, glacier retreat, disruption of hydrological cycles, intensification of water scarcity, and water quality deterioration. The paper emphasizes the urgent need for effecive management, nature-based solutions, government policies on adaptation, equitable policies to ensure sustainable access to freshwater and to strengthen resilience to ongoing climate pressures. To anchor these global paradigms in empirical reality, the study deploys an advanced ecological monitoring framework within the Lviv region of Ukraine, critically assessing the hydrochemical status of the Dniester and Western Bug river basins. The regional observations reveal significant systemic vulnerabilities stemming from antiquated wastewater infrastructure, unchecked nutrient loading, and recent military-induced environmental disruptions.
