French Authorities Grant Temporary Fire Use Permits to Protect Crops from March Frost

In response to forecasts of severe frost from March 26 to March 30, 2026, French prefects have issued exceptional authorizations permitting the controlled use of fire to protect vulnerable crops. In Savoie, the Prefect authorized temporary and regulated vegetation burning during specific night hours—from 9 PM to 8:30 AM—to shield sensitive early-sprouting vineyards and fruit trees from frost damage. Agricultural operators must comply with strict safety and notification requirements, including alerting the Departmental Fire and Rescue Service and local mayors, maintaining fire monitoring and readiness for intervention, and managing smoke to avoid traffic hazards. Meanwhile, in the Vaucluse region, authorities have granted a derogation to the 2013 fire ban allowing farmers to utilize anti-frost fire devices, recognizing the urgency to safeguard crops amid predicted meteorological risks. While burning can temporarily degrade air quality near treatment areas, officials emphasize prioritizing alternative frost protection methods and following regulations carefully. Savoie Prefect Vanina Nicoli stressed the importance of balancing agricultural protection, public safety, and environmental health during this sensitive period.
