Climate change significantly impacts freshwater resources, altering availability, quality, and ecosystem health. Changes in precipitation patterns lead to variable water supply, causing droughts in some regions and flooding in others. Additionally, warming temperatures can exacerbate evaporation rates, diminishing water supply in already arid areas. Altered ecosystems may affect water quality by increasing nutrient runoff and introducing pollutants. Consequently, these changes can threaten drinking water availability, agriculture, and aquatic habitats, underscoring the need for adaptive management strategies to ensure the sustainability of freshwater systems in a changing climate.
