The badly affected villages are Ganggapur, Uzan Gongapur, Goasi, Velkona, Sultanpur and Manikkona.
According to local sources, thousands of people living on the bank of the river have lost their home due to unabated erosion. Arable land, bamboo bushes, academic and religious institutions were also devoured by the river.
Locals said over 1000 acre arable lands would go under the water if necessary steps were not taken immediately.
They also said a large portion of Fenchugonj-Manikgonj-Golapgonj Road had already damaged due to the erosion. Manikkona Sunnia Dhakil Madrasa and Atimkhana (orphange centre), mosques, health complex are at risk.
Meanwhile, homeless Zia Uddin, Ratan Mia, Nurul Islam, Jewel, Bakkar Mia, Bahar Uddin, Nazim Uddin, Al-amin, Muksud Mia and Habibur Rahman who had taken shelter at nearby relative houses and other safer places of the upazila were passing days with hardship.
Communication between Lamagongapur to those villages may be disrupted any time.
Many villagers alleged that illegal lifting of sands from the river was one of the main reasons behind the erosion.
“An influential group of people have been lifting sands from the river for a long time. But the authorities concerned are not taking any measure to stop the activity for unknown reason,” said Kazi Nur Uddin, a resident of Ganggapur village.
Upazila Nirbahi Officer Hure Jannat said they had informed the matter to the deputy commissioner.
Executive Engineer Md Sirajul Islam of Sylhet Water Development Board said they had formed a committee in this regard.
The members of the committee visited the erosion prone area and submitted a report. After getting report, they would submit a DPP (Development Project Proposal) to maintain 350 km embankment of the river, he added.
