What is Ecosystem-based Adaptation (EbA)?
Ecosystem-based Adaptation (EbA) is defined in the Convention on Biological Diversity (CBD) as: “the use of biodiversity and ecosystem services as part of an overall strategy to help people adapt to the adverse effects of climate change.” EbA protects, restores, and manages ecosystems such as mangroves, forests, wetlands, and coral reefs to reduce climate risks and support human well-being.
Healthy ecosystems help to:
- Reduce flooding and erosion
- Regulate water
- Protect coastlines
- Support livelihoods and biodiversity
Types of EbA Measures
In practice, EbA is not limited to on-the-ground restoration. It often combines different types of actions:
Key Elements of a Good Ecosystem-based Adaptation Design
An effective ecosystem-based adaptation integrates ecological, social, and governance dimensions to strengthen climate resilience and long-term benefits. According to the CBD, IUCN, and UNEP, the following elements are key to designing and implementing effective ecosystem-based adaptation:
Key Elements of a Good Ecosystem-based Adaptation Design
The following resources offer practical guidance, tools, and international standards to support the design and implementation of EbA approaches:
- CBD Voluntary Guidelines (2018): Practical guidance for the design and implementation of ecosystem-based adaptation (EbA) and ecosystem-based disaster risk reduction (Eco-DRR).
- UNEP Guidelines for Integrating EbA into NAPs (2021): Comprehensive supplement to the UNFCCC Technical Guidelines for National Adaptation Plans (NAPs).
- FEBA EbA Qualification Criteria and Quality Standards (2017/2022): Practical assessment tool that defines what constitutes high-quality EbA.
- IUCN EbA Resources: Guidance and case studies on nature-based solutions for climate adaptation and resilience.
How does EbA look in practice?
EbA is applied in different ways depending on the ecosystem and local context, aligning natural processes with climate adaptation needs.
Why consider ecosystem-based approaches (EbA) in projects and policies?
EbA is a cost-effective and sustainable approach that generates environmental, social, and economic benefits. A single intervention can generate multiple benefits. For example, watershed restoration can reduce flooding, improve water quality, support biodiversity, and strengthen livelihoods.
Evidence Base and Key Resources
The effectiveness of Ecosystem-based Adaptation (EbA) in reducing climate risk, improving resilience, and supporting sustainable development is supported by a growing body of global assessments and technical guidance:

- UNEP (2021), “Guidelines for Integrating Ecosystem-Based Adaptation into National Adaptation Plans (NAPs).” https://www.unep.org/resources/toolkits-manuals-and-guides/guidelines-integrating-ecosystem-based-adaptation-eba

Why is Environmental Behavioral Analysis (EbA) important in the Caribbean?
The Caribbean is one of the regions most vulnerable to climate change. Small island states face more intense hurricanes, rising sea levels, coastal erosion, reef loss, and changes in rainfall patterns.
Furthermore, the region’s economies rely heavily on tourism, fishing, and coastal infrastructure, increasing their vulnerability to climate impacts.
Main climate and ecosystem challenges in the Caribbean:
Given this combination of high exposure and ecological dependence, ecosystem-based adaptation (EbA) is particularly relevant in the Caribbean. It offers a way to strengthen resilience by working with natural systems that already provide protection, livelihoods, and ecosystem services.
Although the region contributes minimally to global greenhouse gas emissions, it is disproportionately affected by the impacts of climate change, with economic damages that could increase from 5% of regional GDP in 2025 to more than 20% by 2100 if urgent action is not taken.
Ecosystem-Based Agriculture (EbA) in Action in the Real World
- Caribbean Biological Corridor: An IKI-funded initiative supporting ecosystem restoration and the implementation of Ecosystem-Based Agriculture in vulnerable rural landscapes. The project has restored and conserved over 2,600 hectares of land, distributed more than 1.7 million fruit and forest tree seedlings, provided support to 1,140 rural households, and improved access to drinking water for 695 households. More than 10,800 people have benefited from training and awareness campaigns.
- Caribbean Biodiversity Fund (CBF): Has mobilized and disbursed US$27.6 million to support 26 projects in 9 Caribbean countries, including multiple mangrove and coastal ecosystem restoration initiatives, demonstrating growing regional investment in large-scale EbA.
- Mesoamerican Biological Corridor (GEF): A major regional initiative encompassing the Caribbean coastal areas of Central America. It supports forest conservation, ecosystem connectivity, and climate resilience through large-scale landscape restoration and the strengthening of protected areas.
