Broadening climate migration research across impacts, adaptation and mitigation

Abstract

Current climate migration literature focuses on establishing links between climate drivers and migration. However, it often overlooks the broader role that migration plays within the context of climate impacts, adaptation and the connection with mitigation. This Perspective highlights four key research gaps: (1) the effectiveness of migration as an adaptation strategy, (2) how migration interacts with in situ adaptation efforts, (3) migration's impacts on origin and destination communities and (4) feedback between climate mitigation policies and migration. To address these gaps, we propose solutions grounded in strengthening conceptual frameworks, expanded and harmonized data, and advancing methodological innovation. Together, these efforts can inform policy-making to better protect vulnerable populations, allocate resources more effectively and strengthen resilience and justice.
