Since 2000, IOM has been producing its flagship world migration reports every two years. The World Migration Report 2022, the eleventh in the world migration report series, has been produced to contribute to increased understanding of migration and mobility throughout the world. This new edition presents key data and information on migration as well as thematic chapters on highly topical migration issues. 

Chapter 9 on migration and slow-onset impacts of climate change: taking stock and taking action, focuses on migration in the context of the slow-onset impacts of climate change, an area where policy and knowledge gaps remain. It presents some of the key challenges associated with understanding and taking action on slow-onset climate impacts and migration issues, and explores how migration policy and practice can play a role in responding to some of the most pressing challenges.

At the global level, policy discussions have identified some entry points where migration policymakers could be instrumental in promoting positive changes, notably in terms of facilitating migration in the context of slow-onset climate events, and there has been growing interest among both developed and developing States in discussing migration linked to climate impacts in policy terms. Recent examples of migration policy initiatives that address climate impacts on migration, including slow-onset dimensions, are outlined in the chapter.
