A new JRC study explores the intricate relationship between environmental conditions, displacement and migration. 

It draws on nationally representative survey data on individual perceptions and aspirations from more than 160 countries worldwide. 

An empirical analysis links these survey data on people’s individual perceptions about their need to move because of environmental problems, and international migration aspirations, to new data on environmental disasters. 

This addresses the challenge of disentangling the relationships between environmental conditions and people’s aspirations to migrate internationally. 

In particular, the report suggests that, in less developed regions, higher risks of environmental disasters are linked with a diminished desire to migrate internationally.

In least developed regions, individuals who already aspire to migrate internationally step-up their plans in response to the anticipated risks of environmental disasters.

These key findings add additional nuances to the debate on whether and how climate change and environmental conditions might increase international migration. 

The report provides further insights on climate change exposure, vulnerability, ‘environmental immobility’ and different geographical scales of climate-induced migration. 

The findings of the report highlight the importance of targeted policies that address the phenomenon of displacement and environmental mobility, specifically in less developed countries.
