Climate change and increases in extreme events such as droughts and floods, coupled with natural resource degradation, is putting water for drinking, agriculture, and other uses at risk across the globe. Ensuring access to reliable water is an essential component of UNDP’s climate change adaptation service offer. The main areas of work include watershed management and catchment rehabilitation, sustainable land management, improving access to drinking water and water for domestic use, and promoting integrated water resource management systems. Water systems are under threat from pollution, inefficient water use, habitat loss, and climate change and can become the source of local and regional conflicts. UNDP assists local, national, and regional initiatives to identify priorities and agree on governance reforms to promote integrated, ecosystem-based, climate-resilient approaches for water resources management. UNDP supports National Adaptation Plans, climate information, and early warning systems, with ecosystem-based adaptation offering cross-cutting solutions for sustainable water management.
