When the Mehgna River swallowed Mohammad Jewel and Arzu Begum's tin-roofed family home overnight in southern Bangladesh just over a year ago they had no choice but to leave their ancestral village.
The couple fled the next morning with their four young boys to the capital, Dhaka, over a hundred kilometers (62 miles) away from their home in Ramdaspur village in the Bhola district, one of the hardest-hit coastal areas where many villagers regularly lose their houses and land to rivers flowing into the Bay of Bengal.
