France's protests follow similar action in other European countries, including Germany and Poland, ahead of European Parliament elections in June in which the far right, for whom farmers represent a growing constituency, is seen making gains.

The blockading of major thoroughfares around Paris — host of the Summer Olympics in six months — and protests elsewhere in France promised another difficult week for new Prime Minister Gabriel Attal, less than a month into the job.

Protesters said Attal’s attempts last week at pro-agriculture measures fell short of their demands that producing food should be more lucrative, easier and fairer.

Farmers responded with the deployment Monday of convoys of tractors, trailers and even rumbling harvesters in what they described as a "siege" of Paris to gain more concessions. Some protesters came with reserves of food and water and tents to stay at barricades if the government doesn’t cede ground.

"We've come to defend French agriculture," said Christophe Rossignol, a 52-year-old farmer of organic orchards and other crops. The tractors and hay bales at the barricade east of Paris were parked so they formed what looked like an ear of wheat when seen from the air.

"We go from crisis to crisis,” Rossignol said. Some vehicles carried placards declaring "No food without farmers” and "The end of us would mean famine for you.”

Farmers, he said, want President Emmanuel Macron to step in — including to loosen regulations. "We're calling on Macron to put in place more realistic norms," he added.

The government, wary of seeing the protests escalate and with an eye on European elections, has already dropped plans to gradually reduce subsidies on agricultural diesel and promised to ease environmental regulations.

France also said it would push its European Union peers to agree to ease regulations on fallow farmland.

But farmers' organisations said that was not enough.

"Our objective is to put pressure on the government, so that we can quickly find a solution for a way out of the crisis," Arnaud Rousseau, head of the powerful farmers' union FNSEA, said on RTL radio.

The FNSEA said farmers had set up eight roadblocks in the wider Paris region.

In Longvilliers, southwest of Paris, Reuters footage showed tractors, some with trailers, blocking the A10 highway in both directions, with traffic diverted to smaller roads.

Many farmers had attached flags and banners to their tractors. One tractor was carrying a sign that read "Angry farmer," another read: "Farmer: when I was young I dreamed of it and today I'm dying of it."

EU TALKS

Speaking at a blockade near Beauvais north of Paris, Regis Desrumaux, head of the FDSEA union in the Oise region, said the farmers' concerns are broad and include cheap imports, fallow land and red tape.

Macron will make a push for more pro-farming policies at a summit of EU leaders on Thursday, Farming Minister Marc Fesneau said.

Farmers must meet certain conditions to receive EU subsidies - including a requirement to devote 4% of farmland to "non-productive" areas where nature can recover. That can be done by leaving land lying fallow.

Two EU officials told Reuters the EU's executive Commission was looking into changing the fallow land rule, as requested by France, among other options to respond to the farmers' concerns.

The Commission had already temporarily exempted farmers from the rule in response to the Ukraine war and food security concerns.

Unhappy Belgian farmers also blocked highways in southern Belgium and parked tractors near to the EU Parliament in Brussels. Some 30-40 tractors were parked up on the E19 road just south of the Belgian capital on Monday morning, many farmers having spent the night sleeping in their cabs.
