A new study has predicted that the Sundarban's iconic 'Royal Bengal Tigers' could become an extinct species within the 50 years, especially from the Bangladesh part due to climate change.
The study titled 'Combined effects of climate change and sea-level rise project dramatic habitat loss of the globally endangered Bengal tiger in the Bangladesh Sundarban', carried out by a team of Bangladeshi and Australian scientists, revealed that constant rise in sea levels and climate change could bring a catastrophic situation to the mangroves of Sundarban - the iconic Bengal tiger's last coastal stronghold - and the world's biggest mangrove forest.
It has been published in the journal Science of The Total Environment. "Fewer than 4,000 Bengal tigers are alive today," said James Cook University's Professor Bill Laurance, a co-author of the study. "That's a really low number for the world's biggest cat, which used to be far more abundant but today is mainly confined to small areas of India and Bangladesh," he said.
"Spanning more than 10,000 square kilometres, the Sundarban region of Bangladesh and India is the biggest mangrove forest on Earth, and also the most critical area for Bengal tiger survival," said lead-author Dr Sharif Mukul, an assistant professor at Independent University Bangladesh.
"What is most terrifying is that our analyses suggest tiger habitats in the Sundarban will vanish entirely by 2070," said Dr Mukul.
The researchers used computer simulations to assess the future suitability of the low-lying Sundarban region for tigers and their prey species, using mainstream estimates of climatic trends from the Intergovernmental Panel on Climate Change. Their analyses included factors such as extreme weather events and sea-level rise.
