The environment has always been a driver of migration, as people flee to survive natural disasters or, faced with harsh and deteriorating environmental conditions, move to seek opportunities elsewhere. Climate change is expected to exacerbate sudden- and slow-onset disasters and gradual environmental degradation. |
Background: Despite an increase in scholarly and policy interest regarding the impacts of environmental change on migration, empirical knowledge in the field remains varied, patchy, and limited. Generalised discourse on environmental migration frequently oversimplifies the complex channels through which environmental change influences the migration process
Land remains the most fundamental asset for the majority of vulnerable populations living in developing countries, as their livelihoods are directly linked to agriculture. Land degradation is a pervasive systemic phenomenon that can take many problematic forms, including chemical contamination and pollution, salinity, soil erosion, nutrient depletion, overgrazing, deforestation, and desertification.
The IOM Glossary on Migration is an accessible and extensive collection of definitions of migration-related terminology. It is designed for a broad range of actors engaging with migration at the international level. It also provides some insights on regional and national practices.
