The project Migration and Global Environmental Change examines how profound changes in environmental conditions such as flooding, drought and rising sea levels will influence and interact with patterns of global human migration over the next 50 years.

Whilst recognising the opportunities this human movement will present, 75% of which is internal, the project has found that the challenges associated with this interaction have been underestimated.

Sir John Beddington, Professor Richard Black and Neil Adger explain what the final report concludes and what it means for the future of global migration.
