Sitting on the cusp of the tidally active portion of the Ganges Delta, Bagerhat offers an exceptional observatory to mark the march of climate change.
3D interior in BagerhatCyArk
The Old Mosque City is located 60 kilometres (37 mi) from the coast of the Bay of Bengal. For example, 2009 modelling indicated that 32 cm of sea level rise would bring the ingress of salinity to just west of Bagerhat while 88 cm of SLR would leave the area squarely within the salinity zone.

Professor Khandokar Mahfuz-ud-Darain, of nearby Khulna University has observed that the “archaeological sites situated in southern Bangladesh, where the salinity is significantly higher, have been experiencing efflorescence, which is ruining the structures.”

What is efflorescence?
Efflorescence is the migration of salt to the surface of a porous material, where it forms a coating. There is a general perception that there is increased efflorescence, but the dynamic (i.e. method of introduction) is not well documented.
