Seas 'threaten 20m in Bangladesh'
Tuesday, 8 September 2009
Up to 20 million people in low-lying Bangladesh are at risk from rising sea levels in the coming decades, according to new research, reports BBC News.
Scientists predict that salty water could reach far inland, making it hard to cultivate staple foods like rice.
The research comes as the government appeals for $5bn (£3bn) over five years to combat climate change.
In May, Cyclone Aila left thousands homeless, killed many and caused widespread flooding and damage.
The predictions come from the Centre for Environmental and Geographic Information Services (Cegis) in Bangladesh.
It suggests a surprisingly small area of land will be permanently lost to the waters, but notes that vast tracts in the south-west could be inundated every monsoon season.
Ahmadul Hassan, a senior scientist at Cegis, told the BBC that the intrusion of salt water would disrupt rice production in one of Bangladesh's poorest regions.
"These are very poor people, and vulnerable. For four months they'll have nowhere to work," he said.
"So people will migrate to the cities for jobs, because of the uncomfortable situation with sea level rise.
"We are talking about 20 million people," he adds.
According to the researchers, data from 11 Bangladeshi monitoring stations shows an average sea-level rise of 5mm per year over the last 30 years, with climate models forecasting further rises.
Of Bangladesh's total rice production, nearly half is so-called "monsoon" rice and much of that is grown in the areas most vulnerable to flooding.
In an interview with BBC News, Bangladesh's Minister of Disaster Management, Dr Muhammed Abdur Razzaque, said he wanted sea defences similar to those in Holland.
"We have to have new designs for embankments and we have to raise their height," he said.
"We are expecting $5bn over the next five years in support from the international community.
"This must be a grant, not a loan with interest," he stipulated.
The chairman of the Gabura Island "union" or council, Shofiul Ajam Lenin, is calling for the embankments to be far higher.
"If the current design is not changed then not only my union, but the other unions as well will not exist."
The flooding has ruined the island's freshwater supplies and hygiene in the camp is poor.
Among those living in tents on a narrow strip of high ground is Asma Khatun, a 25-year-old widow, who is now eager to leave.
"I think it is not possible to live in this country any longer. We have to move to other countries.
"We can't live here just by drinking this water. It is not possible to live here."
