Erosion by the Padma river devoured at least 300 homestead and vast tracts of croplands at five villages in Harirampur upazila in a week.
The villages are Boro Bahadurpur, Chhota-Bahadurpur, Ujankandi, Kadamtali and Ramkrishnapur.
Many erosion-hit people have already taken shelter on roads, said locals.
A number of villagers were seen leaving their homesteads to shift to safer places in fear of further erosion.
Several school buildings, orphanages and mosques in the areas are under threat of erosion, said the erosion-hit people.
Day labourer Harez Ali Pramanik of Chhoto-Bahadurpur village said his 30 decimals of land went into the river in five hours on Tuesday.
Another day labourer of the area Yunus Ali Pramanik said his house was devoured by the river the same day. He and his family members are passing their days in utter despair. They have taken shelter on a road in the area.
Chairman of Gopinathpur Union Parishad Abdul Kuddus said over 200 houses in his area have gone into the riverbed this year.
More homesteads will go into the river in the next one week if the authorities concerned do not take any initiative to check the erosion.
Harirampur Upazila Nirbahi Officer Md Ilias Mehedi said he informed the higher authorities about the matter. There is a proposal to construct a embankment there.
