Abstract
Adaptation is rapidly becoming a mainstream policy response for addressing biophysical and social vulnerabilities to climate change. Significant capital resources are currently and will continue to be invested in autonomous and anticipatory adaptation processes across a range of geopolitical scales. However, the institutional arrangements for the evaluation of adaptation processes, policies and measures are still in their developmental infancy. Therefore, though adaptation is undoubtedly proceeding, mechanisms for the development of an evidence base for evaluating its success are lacking.
