A partnership between UN Environment, UNDP and IUCN, the Mountain Ecosystem-based Adaptation (EbA) Programme works with national, sub-national and local government authorities, centers of expertise, and local communities in order to reduce the vulnerability of the project countries, its ecosystems and communities to climate change impacts by promoting EbA options, with a particular emphasis on mountain ecosystems. The project’s four components are 1) developing decision-making tools for EbA, including for monitoring and evaluation and assessing resilience, 2) field testing those tools, 3) making investments in and building capacity for EbA at project sites, and 4) making the case for EbA to guide national policies and investments.
