The Economics of Adaptation to Climate Change

[MORE INFORMATION]

To address these objectives, the study was conducted on two parallel tracks: (1) a global track top-down approach, in which national databases were used to generate aggregate estimates at a global scale, drawing on a wide variety of sector studies; and (2) a country level track: a bottom-up approach, in which sub-national data were aggregated to generate estimates at economy wide, sectoral, and local levels. This Synthesis Report integrates and summarizes the key findings of a global study report and seven country case study reports covering Bangladesh, Bolivia, Ethiopia, Ghana, Mozambique, Samoa, and Vietnam (Figure ES-1). By providing information on lessons learned and insights gained on adaptation to climate change from global, country, and sector-level analyses, the hope is to help policymakers worldwide prioritize actions, along with developing a robust, integrated approach for greater resilience to climate risks. The Report begins with the concepts and methodology used for analyses in both the global and the country case studies, including a discussion of study limitations. This is followed by a synthesis of key results from the global and country tracks and a conclusion with lessons learned.
