Angry Dutch farmers converged on The Hague on Wednesday in the latest protest against the government's plans to rein in emissions of nitrogen oxide.

As tractors poured into the city, the Dutch military parked large trucks across strategic roads to prevent farmers from driving into the business and shopping center. Organizers said they expect thousands to attend a rally in the city.

“Take the time to give the sector a chance to use far more effective ways to reduce emissions of nitrogen oxide, which we’ve already been doing for years,” said Ype Reinsma, a farmer from the northern province of Friesland.

In October last year, thousands of farmers, many driving tractors, descended on The Hague, causing traffic chaos across the country. Far fewer tractors appeared to take part in Wednesday's protest and traffic authorities said that it did not create major problems on the country's roads.

Farmers argue that the government’s plans are based on inaccurate readings and calculations by the government-funded National Institute for Public Health and the Environment. New measurements are set to be released on Thursday.

The demonstration comes a day before a debate in parliament on how to rein in emissions of the pollutant nitrogen oxide. Farmers believe they are being disproportionately targeted by lawmakers, saying that aviation, construction and other industries also are major polluters.

“Take the time to give the sector a chance to use far more effective ways to reduce emissions of nitrogen oxide, which we’ve already been doing for years,” said Ype Reinsma, a farmer from the northern province of Friesland.

“Why is everything aimed at the farmers?” he added.

Police issued tickets to a small number of farmers across the Netherlands for driving their tractors on highways and police in The Hague arrested a 33-year-old protester for ignoring their instructions and creating “a dangerous situation on the road.”

Among measures being considered by the government are a multi-million euro fund to buy out farmers who voluntarily want to close their farms and moves to encourage modernization of farms.

“I hope that some ministers wake up and take action and not promise all sorts of things and then do nothing as happened last time. It can’t continue this way,” said another protester, Wim Westerneng.

The Dutch farming lobby is powerful because of the economic significance of agriculture to the economy. The Dutch farmers’ organization, LTO, says exports from the country’s nearly 54,000 farms and agriculture businesses were worth 90.3 billion euros ($98.3 billion) in 2018.
