Is Ecosystem-Based Adaptation Effective? Perceptions and Lessons Learned from 13 Project Sites

But EbA is neither widely nor consistently implemented. It is not sufficiently mainstreamed into national and international policy processes and receives a small proportion of adaptation finance. This is in part due to a weak or poorly consolidated evidence base on EbA effectiveness. This report address this gap, through research conducted on EbA effectiveness at 13 case study sites in 12 countries. The research described in the report was conducted under the project Ecosystem-Based Approaches to Adaptation: Strengthening the Evidence and Informing Policy’, led by the International Institute for Environment and Development (IIED), UN Environment World Conservation Monitoring Centre (UNEP-WCMC) and the International Union for Conservation of Nature (IUCN) in collaboration with 13 in-country partner organizations.
