The environment has always been a driving factor for migrators; these include natural disasters like floods, droughts, earthquakes, climate changes, etc.
The International Organization for Migration defines environmental migrants as the ones who are obliged to leave their origins or home as a result of sudden or progressive environmental changes or conditions, as it has caused a major affect to their living conditions and lives. This movement could be temporarily or permanently, to internal (within the country) or international (abroad) migration.
