Our work in this area is led by the Freshwater Ecosystems Unit, which is based in Nairobi, in collaboration with UN Environment’s regional offices and collaborative centres worldwide, and guided by our Freshwater Strategy 2017-2021. We also engage a number of partners to execute the work at country and regional level, both within and outside the UN system. We work as part of UN-Water, which coordinates the UN’s work on water and sanitation. Our external partners include businesses, academic institutions, and non-governmental organizations.
