- A rare river turtle, hunted for its meat, has been brought back from the edge of extinction.
- The Northern River Terrapin is thriving again, thanks to a partnership between Vienna Zoo and conservationists in Bangladesh.
- The fishermen who once caught the terrapins are now part of the team protecting them.
Some of the rarest turtles in the world have been brought back from the brink of extinction.
The Northern River Terrapin (Batagur baska) is a freshwater turtle once common in the waterways of southwest India, Bangladesh and Myanmar. It has been considered a local delicacy, which is what led to them being hunted until only a few individuals remained in captivity.

But 10 years ago, a team from Vienna’s Schönbrunn Zoo, working with conservation groups and Bangladesh’s Forest Department, launched a project which has seen the terrapins successfully reintroduced into the mangrove forests of the Sundarbans on the country’s south coast.
Black market traders
The project started when local conservationist Rupali Ghosh bought a terrapin dealer’s entire stock to save them from slaughter.
Females are traditionally the most prized for their meat. “Fishermen can get up to $365 for a female – that’s twice the average monthly wage in Bangladesh,” says the Zoo’s turtle project leader Doris Preininger. “They are often kept as talisman’s in village ponds. Traders can get three times that amount by selling the meat and the shells on the black market,” she adds.
They are believed to live for up to 100 years, grow up to 60 centimetres long, weigh up to 20 kilogrammes and, as one of the most endangered species of turtle in the world, are protected by the Convention on International Trade in Endangered Species of Wild Fauna and Flora.
Today, the project is producing 250 hatchlings at its nursery in Bhawal National Park. When the terrapins are old enough, they are taken to the coast and released.
Hunters turned helpers
Once in the wild, the terrapins face predation by another endangered species – the Sundarbans National Park is home to one of the world’s largest populations of Bengal tigers.
But the terrapins now have some unlikely human allies in their fight for survival. Local fishermen, who once hunted the freshwater turtles, are now employed to help protect them. They are part of a team who have helped make this a successful species conservation project.
Not that it’s all been plain sailing. The terrapins are still caught as by-catch in fishermen’s nets and are still being hunted for international trade. Even in their nursery, they are under threat.
“We have only eight females because they are very expensive,” says centre manager AGJ Morsched. “People have broken into the station and one of the keepers was beaten up trying to stop people getting in.”
What’s the World Economic Forum doing about climate change?
Climate change poses an urgent threat demanding decisive action. Communities around the world are already experiencing increased climate impacts, from droughts to floods to rising seas. The World Economic Forum's Global Risks Report continues to rank these environmental threats at the top of the list.
To limit global temperature rise to well below 2°C and as close as possible to 1.5°C above pre-industrial levels, it is essential that businesses, policy-makers, and civil society advance comprehensive near- and long-term climate actions in line with the goals of the Paris Agreement on climate change.
The World Economic Forum's Climate Initiative supports the scaling and acceleration of global climate action through public and private-sector collaboration. The Initiative works across several workstreams to develop and implement inclusive and ambitious solutions.
This includes the Alliance of CEO Climate Leaders, a global network of business leaders from various industries developing cost-effective solutions to transitioning to a low-carbon, climate-resilient economy. CEOs use their position and influence with policy-makers and corporate partners to accelerate the transition and realize the economic benefits of delivering a safer climate.

The good news is the released terrapins are putting on weight – which proves they are feeding successfully – and extending their range. Juveniles have also been found, suggesting they are breeding again in the wild.
The World Economic Forum’s Future of Nature and Business report said the economic recovery from COVID-19 must focus on protecting nature, arguing that commercial interests were not immune from the threats to the natural world.
“There is no future for business as usual – we are reaching irreversible tipping points for nature and climate, and over half of the global GDP, $44 trillion, is potentially threatened by nature loss,” it said.
