Barriers and guidelines for public policies on climate change adaptation: A missed opportunity of scientific knowledge brokerage

Progress in formulating and implementing effective adaptation policies is often hampered by a wide variety of barriers that are well documented in the literature. Among the barriers are lack of awareness, certainty, resources and political commitment. Since these and other barriers can be overcome (e.g., by raising awareness, closing knowledge gaps, and increasing resources), numerous decision-support frameworks (mainly written guidelines) have been developed for this purpose. The present paper takes stock of both the barriers in adaptation policymaking, as documented in the literature, and the guidelines that aim to facilitate public policies on climate change adaptation. It then compares to what degree selected adaptation guidelines serve as knowledge-brokerage tools that provide guidance on how to overcome the barriers addressed in the scientific literature. The comparison shows that adaptation guidelines address barriers of adaptation policymaking neither comprehensively nor systematically. Since most adaptation guidelines focus on (subjective) experiences with good practices than on empirical research findings, we conclude that they represent a missed opportunity of scientific knowledge-brokerage in climate change adaptation.
