The environment has always been an important factor in migration, however, the expected impacts of climate change transform the complex relationship that exists between environmental degradation and migration flows, whether forced or voluntary. Although we don’t know much about the way populations react to environmental degradation, 'climate migration' is generally presented as one of the most dramatic consequences of global warming. This conception reflects a deterministic vision of the phenomenon, in which migrants are solely presented as resourceless victims. However, empirical research shows that migration may also be a strategy that migrants adopt, if they are given the means to do so, in order to adapt to the degradation of their immediate environment.
