Rocket fire, artillery shelling, and explosive devices, such as land mines, from both militaries have ravaged Ukraine’s landscapes and ecosystems. Over a third of all carbon emissions in Ukraine stem from warfare — the largest share of any sector in the country. Fighting has triggered destructive wildfires in heavily forested and agricultural grassland regions of eastern Ukraine. From February 2022 through September 2024, almost 5 million acres burned, nearly three-quarters of which are in or adjacent to the conflict zone.

This is why a collective of forestry scientists in Ukraine and abroad are working together to study war-driven wildfires and other forest destruction, as well as map unexploded ordnance that could spur degradation down the road. The efforts aim to improve deployment of firefighting and other resources to save the forests. It is welcome work, but far from easy during a war, when their efforts come with life-threatening consequences.

“The shelling, it’s an explosive wave, the fire makes everything unrecognizable,” a medic with the National Guard 13th Khartiya Brigade told the Institute for War & Peace Reporting in March. “When they get up, the forest is different, it has all changed.”

When you introduce war, you create fires that can’t be effectively extinguished. “You cannot fly aircraft to suppress fire with water because that aircraft will be shot down,” Maksym Matsala, a postdoctoral researcher at the Swedish University of Agricultural Sciences, explained.

Forests and agricultural land are woven together across Ukraine, meaning wildfires also endanger the country’s food supply. Battle-sparked blazes destroy harvests and eliminate the trees that shelter cropland from drying winds and erosion that can lead to drought — leaving those on the military front lines and Ukrainian citizens at risk of food insecurity.
