For generations, Paban Baroi’s family have guarded a temple to Shiva, the Hindu god of destruction, until Bangladesh’s mighty Padma River wreaked havoc of its own, wiping out the shrine, their home, and 200 other houses in their village.
The 70-year-old and his neighbours are among thousands in the country who will be rendered destitute this year as surging waters and eroding lands reshape the landscape – a phenomenon made worse by climate change.
One day in September, the waterway abruptly changed course and a swath of the tight-knit community in Baroi’s village vanished as the land it stood on was washed away.
“The river current was so powerful,” he said. “Many of us have been living under the open sky for the last few days.”
“It has been a thriving community of carpenters, fishermen, farmers and traders,” said Sohrab Hossain Pir, a councillor for the village. “But now everything is going into the river.”
Bangladesh is a delta country crisscrossed by more than 200 waterways, each connected to the Ganges and Brahmaputra rivers that course from the Himalayas through the South Asian subcontinent.
Periodic flooding that inundates homes, markets and schools has always been a fact of life for the tens of millions of farmers and fishermen who crowd the rivers’ banks, some of the most densely populated areas of the Bangladeshi countryside.
Scientists say climate change has increased the severity and frequency of the phenomenon, with more erratic rainfall causing more cyclones and flash floods.
This year, Bangladesh saw record flooding that killed more than 100 people and cut off seven million others, with relief efforts continuing for months.
The impact is expected to worsen significantly in the coming decades, just as rising sea levels threaten to displace tens of millions of people along the low-lying Bangladeshi coastline and inundate its most fertile farmlands with salt water.
Bangladesh is already rated by the United Nations and civil society groups as one of the countries most affected by extreme weather events since the turn of the century, with entire inland villages wiped from the map.
About 1,800 hectares (4,500 acres) of land will be eroded by rivers in Bangladesh this year and the homes of at least 10,000 people will disappear, according to the state-funded Centre for Environmental and Geographic Information Services (CEGIS).
Residents of disappeared villages often seek a new life in the slums of Dhaka, a sprawling city of 22 million that has doubled in size since the turn of the century on the back of urban migration.
“Many of these people have been displaced by climate change-related reasons,” Ian Fry, UN special rapporteur on climate change, said in a statement that highlighted endemic child malnutrition, a lack of safe drinking water and high rates of human trafficking.
Bangladesh will present a national plan to help manage increasing natural disasters and extreme weather calamities triggered by climate change at November’s COP27 climate summit in Egypt.
That includes keeping river erosion to approximately 1,000 hectares per year – still the size of a large international airport.
At the summit, Dhaka will appeal to leaders of developed nations for urgent funding – it estimates a staggering $230bn is needed by 2050 to mitigate the impact of climate change on the country.
“It is clear to me the burden of the climate change should not be carried by Bangladesh alone,” said Fry, adding that richer nations with higher levels of historical emissions should help foot the bill.
“For too long, countries have denied their responsibility for the sufferings they have caused,” he said. “They should be paying for this.”
In Bangla Bazar, Baroi and his family were yet to find shelter a week after losing their home, while some of his neighbours took refuge in cowsheds.
Those that still have a roof over their heads fretted over where they will turn when the Padma swallows more land.
“I don’t want to go anywhere,” Baroi said. “But if the river devours the entire village, what will happen? Where will we go?”
