Farmers in Greece used tractors to block roads during the 90th anniversary celebrations of the DETh (Development and Economic Transformation) project. The protest, organized by local farmers, took place at the inauguration ceremony of the project's 90th year. Participants drove tractors onto the road to highlight concerns over land use and environmental impact. The event, held in a rural area, drew attention to the long-term effects of the infrastructure on agricultural land. Officials confirmed that the protest was peaceful and did not disrupt the official proceedings. The DETh project, launched in the 1950s, has been a key part of Greece's economic development. Farmers expressed hope for future negotiations on land rights and sustainability.
