Across continents and ecosystems, water moves in a rhythm that keeps our world alive. From vapour rising in the sky to rainfall feeding rivers, wetlands, forests and soils, the water cycle supports communities, climate stability and biodiversity. Yet this natural system is increasingly disrupted as land use changes, ecosystems become degraded and climate change alters when and where rain falls. These shifts threaten water security for millions. Protecting and restoring landscapes, reducing pollution, and adapting to a changing climate are essential to maintaining the availability and quality of freshwater. UNEP is working to advance water security and resilience through holistic approaches to safeguard the water cycle for people and planet.
