 Bangladeshi migrants leaving the coast due to rising sea levels could trigger waves of migration across the country. According to a new study, at least 1.3 million people could be displaced by 2050, according to The Daily Star.  Some mig-rants could displace existing residents, triggering further movement of people. said the study published by the American Geophysical Union, an international scientific group. 600 million people are at risk of being displaced by sea level rise in coastal regions worldwide this century.  “The paper seeks to understand not only the immediate displacement due to sea level rise, but the cascading effects that their migration will trigger throughout the country,” co-author Maurizio Porfiri told the Thomson Reuters Foundation on Wednesday.
 “The model will initially tell you that Dhaka is the place to go, but ultimately, as the place gets overpopulated, people will have to distribute it everywhere. So every place will get a fraction of the migrants. ”
 Bangladesh is often included on lists of countries most at risk from the impacts of rising global temperatures. The study’s authors say their model can be used to assess migration trends caused by any kind of environmental disaster.
 “Mathematicical modelling is the only way we have to ground our future decisions,” the study’s lead author says. The model takes into account human behavior, such as whether people are willing or able to leave their homes and whether they are likely to return later.
