We often hear complaints about how Bangladeshi farmers are increasingly affected by flooding. This should be of little surprise when the land has been subsiding for a long time. There is also a very good reason why people in the past chose to live on higher land!

The problem of subsidence has been well known for a long time, and it is widespread across the Bengal Basin, and not just the local district described above:

Absolute sea levels are rising by about 2mm a year, yet the land is subsiding by 2.2cm a year. A small part of this is due to isostasy, but most is evidently the result of “dewatering”, what we would call water extraction. (see here)

Whatever problems farmers in Bangladesh are having, it has nothing to do with climate change.
