Planning For Inevitable Sea Level Rise

If greenhouse gas emissions were stablised today, it’s a virtual certainty that sea levels would continue to rise past 2100.

This was the sobering assessment of the Senior World Bank environmental consultant Susmita Dasgupta when she presented recently on the impact of climate change on coastal vulnerability.

She has undertaken a detailed study of the risks facing Bangladesh so as to develop a model that can be applied to numerous other countries.

The above chart shows the impact different level rises are estimated to have by 2050. A 3 metre inundation is in blue.

The study is a very comprehensive look at all of the economic and social factors that will be affected.

But rather than just being a theoretical model, the specific adaptation measures needed to survive the sea level rise are actually also being implemented in Bangladesh with World Bank support.
