HOW CAN IT ENHANCE THE RESILIENCE OF ISLAND COMMUNITIES? © Endangered Ecosystem Alliance Presented as Part of Islands Trust Climate Action Series PRESENTATION OUTLINE ¡ How can we respond to climate change? § Mitigation vs. Adaptation ¡ What is Ecosystem-based Adaptation (EbA)? ¡ How can EbA enhance the resilience of island communities? § “Unpacking” the 4 components of what constitute EbA © Endangered Ecosystem Alliance Mitigation An intervention to reduce the emissions sources or enhance the sinks of greenhouse gasses. = Addresses the causes of climate change (i.e. accumulation of greenhouse gases in the atmosphere) Adaptation Adaptation means responding to and preparing for change. = Deals with the impacts (consequences) of climate change HOW CAN WE RESPOND TO CLIMATE CHANGE? § Both approaches are needed ! – simultaneously. WHY DO WE NEED A STRONGER EMPHASIS ON ADAPTATION? Closing the barn door after the horse is gone....!!! WHAT IS ECOSYSTEM-BASED ADAPTATION?

BUT when healthy, ecosystem services can contribute to reducing people’s vulnerability to climate change. © Jason Wilde THE CONCEPT AND IMPORTANCE OF ECOSYSTEM SERVICES Source: Millennium Ecosystem Services (2005) EBA HELPS PEOPLE BECOME MORE RESILIENT Ecosystem-based Adaptation (EbA) is 1. ...the use of biodiversity and ecosystem services 2. ...as part of an overall adaptation strategy 3. ...to help people 4. adapt to the adverse effects of climate change” (official definition by the Global Convention of Biodiversity (CBD) 2009). © Jessica Hutchinson ECOSYSTEM SERVICES AND THEIR LINKS TO HUMAN WELL-BEING By examining the environment through the framework of ecosystem services, it becomes much easier: § To identify how changes in ecosystems influence and can potentially
