Sea-level Rise

Left unattended, 5.3 million of Bangladesh’s poor will be vulnerable to the effects of climate change in 2050

Currently around 43.2 million people or 30% of the population of Bangladesh live in poverty. Alarmingly, this figure includes 24.4 million extremely poor who are not even able to meet the basic needs of food expenditure. These numbers will be even higher if we do not address climate change. Preparation for climate change is essential for poverty alleviation to be sustainable.

Concentration of poor in climate-vulnerable coastal region

In densely populated and land scarce Bangladesh, poor households are disadvantaged with regards to land access, and many end up settling in low-lying regions close to the coast. The poverty map developed by the Bangladesh Bureau of Statistics, World Food Program and the World Bank identifies a high incidence of poverty near the coast, where 11.8 million poor are located in 19 coastal districts in 2010. 

Coastal Wetlands Highly Vulnerable to Sea-Level Rise

Recently, Brian Blankespoor, Benoit Laplante and I investigated potential impacts of sea-level rise on coastal wetlands. Our study indicates a rise in sea levels due to climate change of just one meter could destroy more than 60 percent of the developing world’s coastal wetlands currently found at one meter or less elevation. We estimate that such a rise would lead to economic losses of around $630 million per year.
