Global Hotspots: Key Case Studies

Below are selected examples of climate-driven migration, with images and stories. Citations and data sources can be added below each case.

Isle de Jean Charles, Louisiana, USA

Due to severe coastal erosion and land subsidence, this Indigenous community has launched a “managed retreat” relocation project.

Watch: What can Climate Migration be done?

This video reminds us that climate change is forcing millions of people to migrate, and we must take urgent action to protect their rights and future.

Key Terms

  • Climate Migration: Movement triggered by climate impacts, whether voluntary or forced.
  • Managed Retreat: A planned, strategic relocation of communities away from high-risk areas.
  • Compound Risk: The interaction of climate, social, and economic factors that increase vulnerability.
Legal Gap: “Climate refugees” are not officially recognized under current international law, leaving millions without legal protection.
