NO This policy brief outlines approaches to assess the effectiveness of climate adaptation policies and actions in reducing climate risks. It explains that effectiveness depends on the extent to which interventions lower vulnerability, hazards, and exposure, while avoiding unintended consequences. The document emphasises adaptation as a dynamic, iterative process requiring continuous monitoring and evaluation. It reviews methodological challenges such as baseline definition and attribution, and presents frameworks using ex-ante, implementation, and ex-post assessments. It also highlights the role of ambition, feasibility, and equity, supported by improved data and learning systems.
