Human mobility

Pakistan faces a mounting climate displacement crisis driven by floods and sea level rise. Millions are affected, with migration straining urban centers.

The details of a new visa enabling Tuvaluan citizens to permanently migrate to Australia were released this week. The visa was created as part of a bilateral treaty Australia and Tuvalu signed in late 2023.

Population displacement may become an obvious adaptation margin to climate change in vulnerable regions like sub-Saharan Africa. Market integration, through trade and migration liberalisation, could play an important role in mitigating welfare losses.

New UC research has highlighted the underestimated relevance of water velocity in flood evacuation planning, a danger highlighted by the flooding in Valencia in 2024.

This study analyzes changes in tsunami evacuation risk in Banda Aceh post-2004. While TEBs improved safety, population shifts and infrastructure limits leave 29% at risk.

Accelerated climate change is reshaping migration and displacement patterns worldwide. Extreme weather events, rising sea levels and coastal erosion are making many areas uninhabitable, forcing millions to relocate.

Having an accurate overview of the number of people who have been displaced, their characteristics, the reasons and patterns behind their movement and the duration and impacts of their displacements are instrumental in three main ways.

People in informal settlements, urban deprived areas, refugee camps, prisons, and war zones can be particularly vulnerable to climate threats and natural hazards. A new study, led by IIASA researchers, explores how policymakers can ease their burden.
