THE Belgian city of Ghent yesterday embarked on a radical experiment that seeks to make every Thursday a day free of meat and of the fish and shellfish for which the city is renowned.

"Donderdag - Veggie Dag" has turned the burghers of Ghent into pioneers in the fight against obesity, global warming, cruelty to animals and against the myth that meat-free eating amounts to a diet of soggy lettuce, a slice of tomato and a foul-tasting bean burger.

The city council says it is the first town in Europe and probably the Western world to try to make the entire place vegetarian for a day every week. The Labour Party councillor pushing the scheme, Tom Balthazar, said: "There's nothing compulsory. We just want to be a city that promotes sustainable and healthy living."

Every restaurant in the city is to guarantee a vegetarian dish on the menu, with some going fully vegetarian every Thursday. From September, the city's schools are to make a meat-free meal the "default" option every Thursday, although parents can insist on meat for their children. At least one hospital wants to join in.

A small, dreamy city of spires, bicycles and canals, prospering since the Middle Ages, Ghent may be on to something. It seems to be tapping into an awareness of the cost to human health and the environment of intensive meat and dairy farming. Other towns in Belgium and the Netherlands are making inquiries; there has even been one from Canada.

"We hope that the university, other institutions, enterprises and other towns will jump on the train," the director of the local branch of Flanders Ethical Vegetarian Association, Tobias Leenaert, said.

The organisers cite UN data arguing that meat production and consumption are to blame for 18 per cent of greenhouse gases — more than cars.

"If everyone in Flanders does not eat meat one day a week, we will save as much CO2 in a year as taking half a million cars off the road," the association says.

"I never touch meat, unless I'm at my grandmother's and I need to be polite," Karien De Temmermann, a young member, said.

"This is not a plan for everyone to be forced into vegetarianism," said Wim Coenen, a vegan who works as an importer of vegetarian pet food from Italy. "But it will reduce our carbon footprint. The basic premise is to introduce a way of lessening our meat consumption."

The revolution began last Thursday with a foodie festival at the vegetable market. Ninety thousand town maps listing the best eateries for the meat-shy were handed out. Recipe booklets and food samples were distributed, with fair trade wine to wash down the nibbles.
