This 3-foot-long tuber, in a design tweeted progressing this month, is a threatened succulent furious yam from Madagascar called bako.

It didn’t accurately mangle a Internet, though there is no denying that it’s an eye-catching photo: a smiling male holding a yam that is about 3 feet long.
“That’s a biggest one I’ve seen from that sold species,” says Paul Wilkin, a conduct of healthy collateral and plant health during a United Kingdom’s Royal Botanic Gardens, Kew.
Mamy Tiana Rajaonah, who lives in Antananarivo, Madagascar, took a imitation and tweeted it out to a universe on Nov. 10. Rajaonah has been study yams for some-more than 15 years and is a yam plan manager for a Kew Madagascar Conservation Centre.
Why so many seductiveness in yams? They’re a vital food source on Madagascar, that has some 40 species, of that some-more than 30 are found usually on a island. And a Malagasy people really advantage by eating a tubers.
“You puncture adult one of those tubers, you’ve got food for a family,” says Wilkin, who has been study yams for decades.
They’re healthy, too — a good source of fiber and potassium, for example.
That is a bonus in a nation where some-more than half a children underneath age 5 are chronically malnourished, according to a World Bank.
And yams really fill we up. People in Madagascar generally eat rice to feel full, Rajaonah says. But if there isn’t adequate rice around, a roasted or boiled yam helps. “When we eat yams, we don’t need rice after,” says Rajaonah.
But a island’s yams are in a jam. Their medium is disappearing, partly given of a arise in peanut farming, Wilkin says. And yams, that are a succulent base of climbing vines, are being overharvested.
“I’ve seen 15 or so adult plants surrounded by 100 holes where yams have been extracted,” Wilkin says. “That’s not tolerable for really long.”
Bako — a superlong yam from a twitter — is one of a influenced species.
“People contend it used to be many easier to find them. Now they have to travel a lot serve to find them,” Wilkin says.
“The rate of exploitation is scary. That’s because a prices have left by a roof,” he says.
The cost of bako in internal markets has some-more than quintupled given they initial identified it in a 2008 paper. It went from about $1.25 for a vast square of a berry to some-more than $6 for a smaller piece, Wilkin says.
To make certain locals can get copiousness of yams, a yam plan distributes “seed yams” — cut-up pieces of a bigger berry or yams that aren’t really large and can be used for replanting. The idea is to inspire people to grow their possess furious yams.
Although, it isn’t indispensably easy. “Wild plants don’t always take to being cultivated,” says Wilkin. “We’re only starting to learn how to work with them.”
An additional problem is yam swiping. People will hide into these yam gardens and “try to take a yams cultivated by a other [people],” says Rajaonah.
Meanwhile, on this Thanksgiving holiday, we should note that yams are not a same as honeyed potatoes. While both are tubers that grow underground, honeyed potatoes are partial of a morning excellence family while yams are associated to grasses and lilies.
The yams are starchier and drier than honeyed potatoes, and a Madagascan varieties have white or purple flesh.
If you’re extraordinary to ambience a yam, we might have to do a small berry shopping. In a U.S., according to a Library of Congress, many tubers that are labeled “yams” are indeed honeyed potatoes — so check a excellent imitation on a sticker.
But if we see something that looks like a honeyed potato and is 3 feet prolonged — that could be a Madagascan yam.
