The session will discuss how to measure progress of adaptation of vulnerable communities, groups and ecosystems to the impacts of climate change. More specifically, such aspects of measuring progress of adaptation could help answer whether and how adaptation interventions helped: vulnerable groups, communities maintain or improve their adaptive capacity or resilience, and reduce their vulnerability in the face of climate change; vulnerable ecosystems restore, maintain or enhance the capacity of to continue to provide ecosystem goods and services for local communities, and allow ecosystems to withstand both current and future (anticipated) climate change impacts and other stressors.
