Environmental Migration
Definition
Environmental migration
Environmental migration refers to the movement of people caused by changes in the environment, which can be either sudden or gradual.
It typically occurs when environmental conditions become unfavorable or uninhabitable due to natural disasters, climate change, or other environmental factors.
This migration can be internal (moving within the country) or international (cross-border migration).
Reasons for Environmental Migration
Environmental migration happens for a variety of reasons, including:
Sudden-Onset Events:
Natural disasters like hurricanes, cyclones, floods, and earthquakes cause immediate displacement when homes and infrastructure are destroyed.
Slow-Onset Events:
Climate change impacts, such as sea-level rise, desertification, soil erosion, droughts, and saltwater intrusion, reduce the land's ability to support human populations.
