Oil spill threatens environment in Bangladesh's Sundarbans region

Found in: News

Thousands of litres of oil spilled into the protected Sundarbans mangrove area, home to rare Irrawaddy and Ganges dolphins, after a tanker collided with another vessel on Tuesday. The government has sent a ship carrying oil dispersants to the area, which is inside one of three sanctuaries set up for the dolphins. But environmentalists said the chemicals could harm the delicate ecology of the Sundarbans, a UNESCO World Heritage site.

The head of the local port authority told reporters that fishermen would use "sponges and sacks" to collect the spilled oil, which has spread over an 80-kilometre area. But Amir Hosain, chief forest official of the Sundarbans, admitted authorities were in the dark about what to do. "This catastrophe is unprecedented in the Sundarbans and we don't know how to tackle this," he said. "We're worried about its long-term impact because it happened in a fragile and sensitive mangrove ecosystem."

Rescue vessels have salvaged the tanker, which was carrying an estimated 357,000 litres of oil when it sank. But officials said the damage had been done as the slick spread to a second river and a network of canals in the Sundarbans, which straddles India and Bangladesh. Rubayat Mansur, Bangladesh head of the New York-based Wildlife Conservation Society, said most of the oil appeared to have leaked out of the vessel. "I visited the sunken trawler this morning. Only few hundred litres of oil remain inside, so almost all the oil has spilled into the Sundarbans," he said. Mr Mansur said oil dispersants were "not appropriate for the mangrove ecosystem" and urged local villagers to help collect the oil from nets that have been placed in the river to contain its spread.

Spread over 10,000 square kilometres, the Sundarbans is home to hundreds of Bengal tigers. The delta comprises a network of rivers and canals.
