Adaptation to climate change has become an integral part of climate change policies across the world. Based on the limited literature on the governance of climate change adaptation, the paper first highlights four key challenges governments face in this context, i.e. (i) how to better integrate adaptation policies horizontally across policy sectors and (ii) vertically across levels of government, (iii) how to integrate knowledge in adaptation policy decisions, and (iv) how to involve stakeholders in adaptation decisions. The paper then shows how selected OECD countries address these challenges when developing and implementing adaptation policies and instruments. We identify the most important governance mechanisms on the national level which constitute a distinct governance structure in each surveyed country, and highlight their objectives and specific foci on one or more governance challenges. The paper analyses dominant modes of emerging interaction patterns in the respective governance arrangements.
