A growing body of evidence supports EbA as a cost-effective and successful approach to climate change adaptation, either alone or as part of a broader strategy. Economic tools, such as CBA, can help make the case for investing in EbA; however, many EbA projects don’t adequately document the economic value of their results, leading to a lack of data for conducting detailed analyses that compare different adaptation approaches. Current and new EbA projects should invest in more rigorous valuation of both adaptation results and other development benefits.
