A Complex Nexus
There has always been a fundamental interdependency between migration and the environment, but the reality of climate change adds new complexity to this nexus, while making the need to address it all the more urgent. Both gradual environmental change and slow- or sudden onset natural disasters influence population migration patterns but in different ways. Natural disasters may include geological hazards such as earthquakes or volcanic eruptions. They may also be of an atmospheric or hydrological nature, such as tropical storms or floods, with secondary impacts such as landslides. Some of the latter may be exacerbated by climate change. Any natural disasters may cause affected populations to leave their homes at least temporarily, although return is often feasible in the long run.
