Promoting integrated, ecosystem-based, climate-resilient management of the world’s rivers, lakes and oceans 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, coastline protection, and promoting integrated water resource management systems. Coastal cities, small island developing states, coastal habitats, and marine environments are particularly vulnerable to the impacts of rising seas, coastal degradation, salination, and other climate impacts. To address these interlinked challenges, UNDP’s urban resilience and ecosystem-based adaptation programming is also preparing coastal communities and coastal habitats to become more resilient to climate shocks.
