Migration, belonging, and the sustainability of atoll islands through a changing climate

Abstract

Climate change might catalyze and exacerbate the trend of outmigration from low-lying atoll islands. There is speculation that migration away from atolls may not stop until such islands are abandoned. Yet migration creates both opportunities and risks for the sustainability of atoll communities. There is a trade-off between reduced demographic pressure on increasingly fragile atoll island environments and the financial and human resources necessary to adapt to climate change that can result from migration. Here we propose and analyze belonging as the centripetal force that makes migration a process that enhances the sustainability of atoll populations. We examine the relationship between mig..
