Flooding in Bangladesh forces one family to leave.

Bangladesh is projected to have about a third of South Asias internal climate refugees by 2050 . Millions of people are at risk of being dedisplaced and becoming climate refugees as a result of sea level rise, river erosion, cyclonic storms, and salty water moving inland .

BHO LA: Just over a year ago, when the Mehgna River swallowed Mohammad Jewel and Arzu Begums tin-roofed family home in southern Bangladesh, they had no choice but to leave their ancestral village.The couple fled the next morning with their four young boys to Dhaka, more than a hundred kilometers (62 miles) from their home in Ramdaspur village in the Bhola district, one of the hardest-affected coastal areas in the Bay of Bengal, where many villagers are largely losing their houses and land to rivers flowing into the city.We've grew up seeing the water, we live on the river feeding on fish.Jewel said, however, that it has taken everything from us now.

I had no other choice but to abandon my hometown.The Mehgna, two mighty rivers that pass through Bangladesh, originate in the Himalayas or Tibet and pass through the northern and northeastern regions of the country before flowing down to the sea in the south.The low-lying region is dotted with more than 130 rivers, some of which are prone to major flooding.According to experts, climate change is causing erratic weather conditions in the region, which has resulted in the collapse of riverbanks and the destruction of village after village.

According to scientists, millions of people are at risk of being dedisplaced and becoming climate refugees as a result of sea level rise, river erosion, cyclonic storms, and salty water moving inland.According to a World Bank survey released last year, Bangladesh is projected to have about a third of South Asia's internal climate refugees by 2050.A year after Jewel and Begum visited their family's old home in Ramdaspur, even more homes were washed away, the river flowing through new territory.As an infant, Jewel said the river never came so close, but it came closer every year.

The place where we are now will be eroded in a few days by the river, he said, just feet from their old family home.The village was once brimming with tiny shops and tea shops, markets, and green spaces, according to him.The area was fertile.However, people were compelled to abandon their homes over the years.

Even though the family's lack of water has made life difficult in recent years, his wife Arzu Begum also feels pain as she passes through the remnants of their former community.Because of the danger of drowning, I raised my youngest son by tying his legs with a rope attached to the door of my house.Begum remembers that the house was full of water when the tide came and that my youngest child would always turn toward water.All of them were destroyed by river erosion, and people were scattered, she said, referring to the homes of friends and neighbors.

I immigrated to Dhaka in 2012.We lived in a small neighborhood.Now you can only see the river and no one else there.We have become homeless, she said.

Officials are also constructing shelters for climate migrants and upgrading the water supply in Bangladesh's northern region, but the Jewel and Begums families are one of many people who are unable to benefit from these initiatives.Officials are also working with smaller cities to be designated climate havens for migrants.Experts claim that limiting global-warming greenhouse gas emissions, especially in high-emitting countries such as the United States, China, and India, will reduce more severe weather events around the world.Begum and Jewel may be away from the swelling Mehgna in Dhakas poor Mirpur neighborhood, where they live in a one-room hut lowered over a swamp, but they say they are unable to adapt to the fast-paced city life.

Begum said, Our monthly income was sufficient to support our family, referring to their life back in Ramdaspur.We are now obligated to pay house rent and spend such a lot of money on food that what we earn isnt enough for the family, she said.Begum earns an additional 4,000 takas ($45) per month by cleaning two separate houses.Her husband earns 12,000 takas ($136) per month by going door to door and sorting household waste.

Jewel, a fisherman who used to fish in his village, says they lived there joyfully and that they wanted to provide a better life to their children.I wanted to raise my children properly and send them to school.However, I have no idea how we will survive now that everything is so uncertain.My children are growing up, but I can't take care of them, he said.

I hate my job.When I think about whether or not I will survive without a job, I remain content.Life isn't an easy job.
