'They have left us all to die'
2007-03-26 10:02
Moushuni Island - Sheikh Alauddin, like hundreds of other residents living on West Bengal's Moushuni island, has never heard the term "global warming". But he is living with its consequences.
"At night we just pray to God, and hope the sea does not
drown us," the 60-year-old told Reuters in Poilagheri village on the sparsely-populated island, part of the Sunderbans
national park and the world's largest mangrove forest.
When the tide comes in, sea water laps at the top of a mud
embankment that towers six metres above Alauddin's
adjacent house and is all that keeps it from being washed away.
After a 10-year study in and around the Bay of Bengal,
oceanographers say the sea is rising at 3.14 millimetres a year
in the Sunderbans against a global average of 2 mm, threatening
low-lying areas of India and Bangladesh.
"At least 15 islands have been affected but erosion is
widespread in other islands as well," said Sugato Hazra, an
oceanographer at Jadavpur University in Kolkata, the capital of
West Bengal.
A United Nations climate panel, which grouped 2 500
scientists from 130 countries, concluded last month that human
activity was causing global warming and predicted more
droughts, heatwaves and rising seas.
'Where do we go?'
But for the Sunderbans, made up of hundreds of islands and
criss-crossed by narrow water channels and home to many of
India's dwindling tiger population, the threat is more
immediate.
"The crops have failed due to scanty rainfall but where do
we go?" says Alauddin as his family of twelve stares at their parched farmland.
A combination of drought and then heavy rainfall this year
and increasing soil salinity have made it impossible to grow
enough food to survive on traditional agriculture alone.
"We now depend on fishing in the high seas and sometimes
even eat leaves from different plants to survive," a
frail-looking Jameel Mullick said.
At least four million people live in the islands spread across
9.630 square kilometres of mangrove swamps.
Tigers threatened
Top climate experts on the UN panel predicted that
temperatures would increase by between 1.8 and 4 Celsius and sea levels would rise by between 18 and 59 centimetres to submerge islands in the 21st century.
The impact could be even greater if ice sheets in
Antarctica and Greenland thaw.
The 400 or so families living on tiny Moushuni know what is
coming.
Two nearby islands disappeared beneath the sea after
residents were forced to leave, and the sea has swallowed about
100 square kilometre of mangrove forest in three decades in the
Sunderbans.
"Global warming and rising sea levels are already having a
telling effect on the tiger's habitat," said Pronobes Sanyal of the National Coastal Zone Management Authority.
Rapid erosion over the last five years has destroyed
mangrove cover up to 15m inland on several islands,
environment experts say.
Salt and sorrow
For centuries, the mangroves fed on both saline and fresh
water - tides brought sea water upstream and mixed it with
water from the Ganga and Brahmaputra rivers.
But now rising sea levels are pushing salt water inland.
Sixty year old Ayesha Khatoon stood on top of a mud
embankment in Moushuni that has been breached at least seven
times in the past 10 years.
"There was a lovely mud road surrounded by trees beyond
this embankment and we had 1.2 hectares of farmland
which the sea swallowed in the last few years," recalled
Ayesha.
"No one visits us now and they have left us all to die," she said, tears welling in her eyes as she hugs her young grandson.
Rapid felling of trees on the islands - in part to fuel
two small power plants - is adding to erosion woes.
Dilip Maity, a farmer, lamented how he had erred in hacking
down several rows of trees, an act which weakened and led to
sea water flooding his small farm.
Alarmed, West Bengal's minister for the Sunderbans, Kanti
Ganguly, said the islands had to be protected.
"We have realised it now and have taken a decision to raise
heights of the mud embankments and increase mangrove cover in
Sunderbans," he said.
Oceanographer Hazra says it might be too late.
