Ecosystem-based Climate Adaptation

Ecosystem-based adaptation (EbA) is a relatively new concept, which capitalizes on the ability of healthy ecosystems to assist in human adaptation to climate change. EbA has been defined as "the use of biodiversity and ecosystem services as part of an overall adaptation strategy to help people to adapt to the adverse effects of climate change."

In many cases, because healthy ecosystems provide multiple co-benefits (such as carbon storage and pollination services), in addition to the specific adaptation enhancement, they are potentially more cost-effective than other adaptation options, including hard-engineered solutions. Yet, they are often overlooked.

CI is implementing ecosystem-based adaptation in marine, terrestrial and coastal regions as a means of improving livelihoods and conserving biodiversity in the face of climate change. The aim is to use EbA to buffer impacts of climate change in three countries where we have strong track records, partners and relationships with government — Philippines, South Africa and Brazil.

Browse by Outcome

Vulnerability Assessments
These assessments determine and prioritize Eba actions to implement.

Pilot Projects
Projects test the feasibility of implementing EbA actions.

Monitoring and Cost Effectiveness
Tracking the implementation and results of activities.

National Policy
Results of pilot projects inform national policy, which amplifies their impact.

International Policy
Through engagement with international policy fora, lessons from the project can inform the global dialogue.

Browse by Country

Brazil
Nearly 500,000 people are supported by ecosystems vulnerable to climate change.

Philippines
With a rising population, pressures will result in erosion and degradation of the natural coast.

South Africa
In the face of climate change, this region could move from semi-desert to a desert in the next 50 years.
