An international comparison of factors behind evacuees' refusal of repatriation to their country of origin, and measures to address the issue

Research grant

Project Description

Among evacuees of large-scale natural disasters such as earthquakes and tsunamis, some individuals desire to forego repatriation to their country of origin despite the option to return. In these cases, problems can arise ranging from population decline in originating countries to overcrowding in schools, a lack of medical facilities, and conflict with local citizens in the destination country. This joint international study investigates the root causes of evacuees denying repatriation in connection with any of the three major recent natural disasters in Asia, and seeks to propose measures to address the issue.
