When a cyclone destroyed her home two years ago, Shahana Begum joined the swelling ranks of Bangladeshi "climate refugees" who, experts say, could one day overwhelm the capital Dhaka.
Shahana's family, like more than half a million people in the impoverished nation, lost her shanty home and all her belongings when cyclone Sidr slammed into southern Bangladesh in November 2007, claiming more than 3,500 lives.
"I moved to Dhaka because there was nowhere else to go," said Shahana, for whom home is now a slum on the dry banks of the capital's biggest river.
"My husband now works a little as a fisherman up here but we want to take our two daughters back to the south. There's no home for us there and no real work," the 25-year-old said.
Almost two years after the cyclone, the United Nations and aid groups say thousands of families like Shahana's have yet to receive assistance to rebuild their lives.
In May this year, another cyclone, which killed 300 people and left 375,000 people homeless, also destroyed 4,000 kilometres (2,500 miles) of roads and embankments.
The country's leading climate change scientist says it is a sign of things to come.
"It used to be that we would have a big cyclone every 15 to 20 years. We are getting a big one now every two or three years," said Atiq Rahman, who was on the UN's Inter-government Panel on Climate Change (IPCC).
