The environment has always been a driver of migration, as people flee to survive natural disasters or, faced with harsh and deteriorating environmental conditions, move to seek opportunities elsewhere. Climate change is expected to exacerbate sudden- and slow-onset disasters and gradual environmental degradation. |
Internal displacement associated with slow-onset environmental change and disasters is a complex and dynamic phenomenon. Often hard to distinguish from internal migration, displacement driven by gradually evolving environmental change is primarily a development issue.
