What can we do about climate migration?

Bangladesh is a country that is exceptionally vulnerable to climate change. With a low elevation and high population density, as well as poor infrastructure and an economic reliance on farming, it is naturally susceptible to extreme weather. The intensification of conditions due to climate change means more people are being driven from their homes and land by sea level rises, storms, cyclones, drought, erosion, landslides, flooding and salinisation of the land. It's estimated that by 2050, one in every seven people in Bangladesh will become a climate migrant. But Bangladesh is far from being alone. Across South Asia, it’s estimated that more than 40m people will be displaced; worldwide, the figure runs into the hundreds of millions. Climate migration is coming. The question is, what are we going to do about it?
