Sudden and slow-onset events as triggers of migration
In current research we have considered sudden-onset and slow-onset events as triggers of displacement and migration in the affected regions. Lack of data on environment-induced migration, the poor capacity to support internally displaced persons, low preparedness level for natural hazards, lack of measures to decrease disaster risk, lack of budgeting, poor early-warning information system are the main contributors to insufficiency of the measures addressing environment-induced migration. However, the most affected regions can be outlined. The Pacific and South Asia appeared to be the most affected regions in terms of both sudden and slow-onset events. Sudden-onset events may reflect only short-term vulnerabilities of the regions and in case of setting proper priorities in policy development, their harmful effect can be mitigated to some extent. Slow-onset events, in turn, may include both short and long-term vulnerabilities and pose much greater displacement risks in affected regions. Furthermore, slow-onset events along with regional specific drivers of migration and displacement can initiate great harm. In current paper, we emphasize the importance of focusing on slow-onset events in affected regions and outline some interactions between slow-onset events, regional drivers of displacement and loss of adaptive capacity and highlight economic and social tense which arises as a result of mentioned interactions. We also present migration framework in the conditions of exposure to slow-onset events demonstrating causal effects of slow-onset events on economic and social factors affecting migration decisions.
