Disaster and climate related displacement and migration

More extreme weather and other adverse effects linked to climate change are increasingly affecting displacement and migration and undermining human security. Upward of 20 million people each year on average are displaced by floods, hurricanes, cyclones, droughts, and other weather-related disasters. Meanwhile, environmental degradation and slow-onset changes such as coastal erosion and sea-level rise are increasingly forcing significant numbers of people from their homes. Disproportionately affected are disadvantaged and vulnerable populations, indigenous peoples, and local communities dependent on agriculture or coastal livelihoods to survive. Least-developed, fragile, and conflict-ridden countries face the greatest challenges in adapting and responding to disasters and other climate-related shocks.
