Ecosystem-based adaptation (EBA) is quickly becoming a buzz-word in climate change and nature conservation policy arenas. Effective EBA programs and projects require a careful analysis of this complex concept, which attempts to link social systems and ecosystems in creating resilience to climate change impacts. For instance, an effective EBA program may require inter-sectorial coordination in traditionally antagonistic realms, such as agricultural extension and nature conservation. At the same time, planning for EBA should include participatory decision-making to ensure all voices have a say and promote equitable access to vital livelihood resources, such as water, land or forests. As a starting point it is necessary to assess the root causes of vulnerability of social and ecological systems to identify the most appropriate policy and management options. This workshop will generate a reflection and draw lessons for effective EBA implementation by looking at examples from various EBA-related projects around the world. Workshop organizers will use GIZ’s vast array of participatory tools and techniques to promote a discussion and answer the following questions: Which variables should we look into when performing vulnerability analyses that will aid us in creating more effective EBA measures? How can we achieve a proper coordination of traditionally disparate sectors in launching effective EBA policies? What makes EBA a distinct option to augment resilience while at the same time pave the way to sustainability in an uncertain climate regime?
