Adaptation to climate change is increasingly part of urban policy agendas around the world. Most research has focused on municipal-level adaptation, while less is known about processes carried out at the metropolitan scale. This systematic review aims to identify the main themes emerging from the literature on climate adaptation governance in metropolitan areas, discussing their relevance in the context of the wider scholarly debate. Based on a thematic analysis performed on academic publications addressing metropolitan-scale adaptation governance, the review identifies a number of emerging narratives in the literature. These concern issues such as the presence of divergences and inequalities within metropolitan regions, seen in the sampled literature as factors that can hinder effective adaptation planning at the metropolitan scale, and the need for greater metropolitan coordination to work across administrative boundaries. The review concludes by suggesting that future research address some identified gaps and outstanding issues, including a certain degree of conceptual ambiguity and the need for greater engagement with the wider literature on metropolitan governance.

大都市地区气候适应治理：对新出现的主题和问题的系统回顾

适应气候变化日益成为世界各地城市政策议程的一部分。大多数研究都集中在城市层面的适应上，而对大都市规模上进行的过程知之甚少。本系统综述旨在确定大都市地区气候适应治理文献中出现的主要主题，并在更广泛的学术辩论背景下讨论它们的相关性。基于对大都市规模适应治理的学术出版物进行的主题分析，该评论确定了文献中的一些新兴叙述。这些问题涉及大都市地区内存在的分歧和不平等等问题，在抽样文献中，这些问题被视为阻碍大都市规模有效适应规划的因素，以及需要加强大都市跨行政边界的协调。审查最后建议未来的研究解决一些已发现的差距和突出问题，包括一定程度的概念模糊性以及需要更多地参与有关大都市治理的更广泛文献。
