Ecosystem-based adaptation: Series synthesis
Ecosystem-based adaptation (EbA) is a nature-based approach that uses biodiversity and ecosystem services to help people adapt to the adverse impacts of climate change. In addition to improving climate resilience, EbA interventions can provide biodiversity conservation and other human well-being co-benefits, including habitat for food species, non-timber forest products for household use, carbon sequestration for climate mitigation and pollination for agricultural productivity. The integration of EbA approaches into community-based adaptation strategies can address many of the priorities identified by vulnerable countries and people, such as reducing disaster risk and improving natural resource conditions.
This document provides an introduction to EbA and common EbA approaches; summarizes evidence related to EbA and food security, water security, coastal populations and extreme events; and discusses cost-effectiveness, elements of a successful EbA approach and enabling conditions. It draws from a series of evidence summaries and case studies generated by USAID highlighting the potential role of EbA in addressing climate vulnerabilities and contributing to development results.
