Umweltmigration

Umweltmigration, or environmental migration, denotes the movement of people driven by environmental factors. These include rapid-onset events such as floods, storms, and wildfires, and slow-onset changes like drought, sea-level rise, and land degradation. Movements can be internal or cross-border and may be voluntary or forced, temporary or permanent, depending on local conditions and available adaptation options.

Drivers are often climate-related but interact with economic, social, and political factors. Damage to housing, livelihoods, water resources, and ecosystems can push people to migrate. Distinguishing Umweltmigration from other migration is challenging, since many migrants have mixed motives and environmental factors may amplify existing vulnerabilities.

Impacts vary by context. Displacement can affect housing, employment, health care, and social protection; host communities may experience service strains or gains from new labor. Women, youths, and marginalized groups face specific risks and needs, including protection from exploitation and access to social protection.

Policy responses include disaster risk reduction, climate adaptation, and mobility-aware planning. The legal status of environmental migrants is not standardized; international frameworks and national relocation policies are used to protect rights, while agencies such as IOM advocate for voluntary, safe mobility and informed relocation where necessary.

Scholarly and policy debates address definitions, data reliability, and whether mobility constitutes adaptation or abandonment. Critics highlight protection gaps and securitization risks. Notable patterns appear in small island developing states, drought-prone regions of Africa and Asia, and rapidly urbanizing coastal areas.
