Adapting to climate change through ‘managed retreat’
In our new study, just published in Nature Climate Change, my coauthors and I analysed 27 cases of #managed_retreat from 22 countries around the world. We estimate that, over the past three decades, around 1.3 million people have been relocated through managed retreat in response to natural hazards such as tropical storms, flooding, erosion, earthquakes and tsunamis.
[...] Sea level rise threatens to inundate 70-190 million people by 2100. For some, a coordinated, strategic #relocation might be the preferred option, while for others, sea walls and elevated infrastructure might be the solution.
But so far, the obstacles to managed retreat have largely prevented residents and decision-makers from even contemplating it in most cases. #Climate change might make us reconsider.
