France wildfires: Blaze threatens strategic defense sites, deals heavy blow to regional economy
Wildfires raging across France’s Gironde department have forced evacuations and triggered emergency protective measures at strategically important aerospace and defense sites near Bordeaux, crippling one of the country’s most vital industrial clusters.
The blaze, which broke out on July 22, has already scorched roughly 42,000 hectares, forced about 220,000 people to flee their homes and destroyed an estimated 240 residences, according to the latest official figures. While the fire was described as “stabilized” early Tuesday after a relatively calm night, local authorities warned that rising temperatures and falling humidity could quickly reignite conditions.
Among the industrial facilities affected are plants run by ArianeGroup, Dassault Aviation, Airbus Atlantic and missile-propulsion specialist Roxel. The French Defense Ministry said 1,500 military personnel have been deployed since Saturday to support firefighting efforts and to help secure sensitive sites in coordination with other government departments.
ArianeGroup, whose local facilities manufacture propulsion systems for Europe’s Ariane rockets and France’s M51 ballistic missiles, told AFP on Monday it remains in “constant contact” with local and national authorities. “The issues related to the protection of ArianeGroup sites are being addressed,” the company said.
French broadcaster TF1 reported that Roxel, a subsidiary of European missile manufacturer MBDA, operates a high-risk industrial complex in Saint-Médard-en-Jalles, where it produces solid-propellant systems for tactical missiles. Nearby complexes belonging to Dassault, Safran and Thales also appeared vulnerable. Roxel told Le Monde that it had taken “the necessary measures” to protect operations and employees, with support from authorities.
According to Defense News, Dassault Aviation has been working with France’s Directorate General of Armaments and prefectural authorities. The company said it had transferred sensitive equipment from its Martignas plant and Cestas logistics centre to its Mérignac site and nearby Air Base 106. Most employees at its Mérignac and Martignas facilities have been told to stay at home. The Mérignac facility handles final assembly and flight testing of Rafale fighter jets and Falcon business jets; the Martignas plant specializes in aerostructures.
Airbus Atlantic also evacuated employees from its Salaunes facility at the authorities’ request. That site produces fuselage components for Airbus A220 and A350 aircraft.
The disruption to strategic industry is part of a much broader economic shock across Gironde. More than 13,000 businesses lie in evacuation zones — including roughly 7,000 craft businesses and 6,300 retailers, according to France’s Economy Ministry. Many have been unable to operate normally because of evacuation orders. The Bordeaux-Gironde Chamber of Commerce and Industry estimates that around 130,000 employees have been prevented from working.
Economy Minister Roland Lescure described the wildfires as an “economic thunderbolt” hitting a region that “did not need it.” Carsten Brzeski, ING’s global head of macroeconomics, said the overall impact “should become measurable” through lost working hours, lower productivity and disrupted logistics.
The French government announced emergency support on Monday for affected businesses in Gironde, the Landes and the Var. Companies in evacuation zones can use the state-supported partial-unemployment scheme. France Assureurs extended the deadline for submitting claims until August 31. A meeting at the Economy Ministry on Thursday is expected to provide “more precise answers” to affected companies, according to Industry Minister Sébastien Martin.
Tourism businesses, meanwhile, face cancellations and closures during what should have been one of their busiest periods. Companies across the affected area also report spoiled stock, interrupted supply chains and employee absences.
The fire is also disrupting activity in the Landes de Gascogne forest, one of the main centres of France’s commercial timber industry. The timber sector is the third-largest industrial sector in Nouvelle-Aquitaine, supporting some 56,000 jobs — about 34,000 of them linked to the Landes de Gascogne forest — and generating an estimated €10 billion in annual revenue.
Bordeaux’s vineyards had escaped direct fire damage as of July 27, according to Le Monde, but winemakers warned that smoke could taint grapes and affect future vintages.
The eventual economic cost is likely to extend far beyond visible destruction and insured losses. According to Allianz Research, only around 10% of European economic losses from heatwaves, droughts, wildfires and other climatological events were insured between 1980 and 2022. By comparison, more than one-third of losses from storms, hail and wind were covered. These calculations exclude deaths, healthcare costs and lost productivity — often a substantial share of the true cost.
A study published in Nature Sustainability estimated that California’s 2018 wildfires caused $148.5 billion in total damage. Direct capital destruction represented just 19% of that figure, while health costs accounted for 22% and indirect economic disruption for 59%. The study found that supply-chain effects spread far beyond the burned areas, with more than half of indirect losses occurring outside California.
The European Central Bank separately estimates that only about one-quarter of climate-related catastrophe losses in the EU were insured between 1980 and 2023. Insurance Europe puts the average protection gap — the share of losses left uninsured — at 53% in France and 60% in Spain between 2015 and 2024, based on Munich Re data.
“With the wildfires, the bittersweet consequence, as with other natural disasters, is that it will actually lead to positive economic activity once the rebuilding starts,” Brzeski said. Still, he noted that households, insurers and the government will ultimately bear the cost of reconstruction.
With temperatures forecast to rise again this week, businesses and industrial operators face the prospect that evacuations and production interruptions could be extended.
