Adapting to Coastal Climate Change: A Guidebook for Development Planners (the Guidebook) provides a detailed treatment of climate concerns in coastal areas. The Guidebook proposes an approach for assessing vulnerability to climate change and climate variability, developing and implementing adaptation options, and integrating options into programs, development plans, and projects at the national and local levels. This is known as a vulnerability and adaptation or V&A approach. The Guidebook includes practitioner briefs on 17 coastal adaptation measures and strategies. Each brief describes the measure’s relevance, purpose and application to climate change, information and data requirements, design considerations, suggestions for improving likelihood of success, and list of resources.
