Bangladesh gaining land, not losing: scientists

New data shows that Bangladesh’s landmass is increasing, contradicting forecasts that the South Asian nation will be under the waves by the end of the century, experts say.

Scientists from the Dhaka-based Center for Environment and Geographic Information Services (CEGIS) have studied 32 years of satellite images and say Bangladesh’s landmass has increased by 20 square kilometres (eight square miles) annually.
Maminul Haque Sarker, head of the department at the government-owned centre that looks at boundary changes, told AFP sediment which travelled down the big Himalayan rivers — the Ganges and the Brahmaputra — had caused the landmass to increase.


The rivers, which meet in the centre of Bangladesh, carry more than a billion tonnes of sediment every year and most of it comes to rest on the southern coastline of the country in the Bay of Bengal where new territory is forming, he said in an interview on Tuesday.


The United Nations Intergovernmental Panel on Climate Change (IPCC) has predicted that impoverished Bangladesh, criss-crossed by a network of more than 200 rivers, will lose 17 percent of its land by 2050 because of rising sea levels due to global warming.

“Satellite images dating back to 1973 and old maps earlier than that show some 1,000 square kilometres of land have risen from the sea,” Sarker said.


“A rise in sea level will offset this and slow the gains made by new territories, but there will still be an increase in land. We think that in the next 50 years we may get another 1,000 square kilometres of land.”
