Wildfires devastating richer areas but fewer hectares burned globally – study

‘Megafires’ in California, Canada, South Korea and Europe in 2025, but changes to farming slowed spread in parts of Africa

“Devastating” wildfires ripped across the wealthier parts of the world in 2025, a study has found, even as globally, the area ravaged by flames fell.

Catastrophic blazes claimed lives, homes and jobs last year in California, Canada, Europe and South Korea. But the 335m hectares burned was the second-lowest since 2002, the review found, largely owing to the expansion of African farms that have fragmented landscapes and hampered the spread of large savannah fires.
