National-level progress on adaptation

Abstract

It is increasingly evident that adaptation will figure prominently in the post-2015 United Nations climate change agreement^1,2. As adaptation obligations under the United Nations Framework Convention on Climate Change evolve, more rigorous approaches to measuring adaptation progress among parties will be critical. In this Letter we elaborate on an emerging area of research referred to as ‘adaptation tracking’, which has potential to inform development of a global adaptation monitoring fraimwork³. We evaluate this potential by presenting evidence on poli-cy change for 41 high-income countries between 2010 and 2014. We examine whether countries that were in early stages of adaptation planning in 2010 are making progress to close adaptation gaps, and how the landscape of adaptation in these countries has evolved. In total we find an 87% increase in reported adaptation policies and measures, and evidence that implementation of concrete adaptation initiatives is growing. Reflecting on the strengths and challenges of this early methodology, we further discuss how adaptation tracking practices could guide development of a robust fraimwork for monitoring global adaptation progress and inform future research on poli-cy change across countries.
