Greek farmers are set to take their tractors onto the roads on Sunday, Nov. 30, protesting delayed payments of overdue subsidies from, OPEKEPE the national body responsible for managing and paying out agricultural subsidies in Greece, soaring production costs and persistently low market prices for their goods.

The main protest front will form at the Nikaia junction in Larissa, where tractors from Larissa, Elassona, Tyrnavos, Agia and Farsala are expected to converge. According to the president of the Platikampos Agricultural Cooperative, farmers intend to move onto the national highway and block traffic. A second major roadblock is planned in Karditsa, along the E65 motorway.

The escalation comes as frustration mounts over financial uncertainties in the sector. The government’s vice president has signaled that Dec. will be the key month for settling payments to farmers, an effort aimed at easing tensions.

The Ministry of Rural Development notes that this year’s subsidy advance is 25% lower than last year’s because it was calculated strictly on the basis of verified data.

More than 44,000 producers were excluded from the payment altogether—either because their declared plots were deemed ineligible, discrepancies appeared in property identification, or available grazing land did not sufficiently match the livestock declared by herders.

Starting Monday, Dec. 1, farmers will have the opportunity to file formal objections, hoping to reclaim payments they believe they are entitled to.
