Synthesis report on efforts undertaken to access the costs and benefits of adaptation options, and views on lessons learned, good practices, gaps and needs

Abstract

Building upon the technical paper containing a review of the existing literature on the potential costs and benefits of adaptation options (FCCC/TP/2009/2), this report synthesizes information contained in submissions from Parties and relevant organizations, and other relevant sources, on efforts undertaken to assess the costs and benefits of adaptation options. A summary of lessons learned and good practices is provided. The report also identifies remaining gaps and needs relating both to a need for more comprehensive assessments of costs and benefits and to methodological gaps and needs encountered by adaptation researchers and planners when undertaking such assessments.
