THE HAGUE, Netherlands (AP) — Farmers driving tractors blocked highways in the Netherlands on Monday in the latest protest sparked by a government pledge to rein in pollution emissions, a move that will hit the country's agriculture sector.

Authorities urged motorists to check traffic updates before setting off, amid the protests that follow a gathering last week of tens of thousands of farmers in the central Netherlands that also caused traffic chaos around the country.

“We advise road users to be extra alert,” the government's road and water department said in a statement. At least three highways were affected by the protests.

Local broadcaster Omroep Brabant showed a truck dumping large, plastic-covered bales of hay on a highway near the town of Liessel, some 150 kilometers (93 miles) southeast of the capital, Amsterdam. On at least two more highways, farmers drove or parked their tractors, snarling traffic.

The Dutch governing coalition has mandated reductions in emissions of nitrogen oxides and ammonia of up to 70% in many areas of the country close to protected nature areas — even reaching as high as 95% in some places. The government has been forced to act after courts in recent years began blocking permits for infrastructure and housing projects because the country was missing its emissions targets.

The government has earmarked an extra 24.3 billion euros ($25.6 billion) to finance agricultural reforms that will likely make many farmers drastically reduce their number of livestock or to get rid of them altogether.

The pollution reduction targets, which have to be achieved by provincial governments, have been opposed even by members of Prime Minister Mark Rutte’s own party and other members of his coalition. Provincial governments have been given a year to formulate plans to meet the targets.
