The decline in freshwater resources poses severe risks to ecosystems, agriculture, and human livelihoods. For instance, the Parana River's reduced water levels have disrupted grain shipping and hydroelectric power generation. In Bolivia, the near disappearance of Lake Poope has devastated fisheries and Indigenous communities. Similarly, Lake Mead's shrinking levels threaten water supplies for millions in the U.S. Southwest. These changes also exacerbate desertification, reduce biodiversity, and increase the vulnerability of affected regions to climate-related disasters.
