Indigenous Fire Management Recognized as Climate Solution in Landmark Global Study

For tens of thousands of years, Indigenous peoples across Australia, North America, and the Amazon basin have used controlled burning as a land management practice — deliberately setting small, cool fires to reduce fuel loads, promote biodiversity, and prevent catastrophic wildfires. A landmark global study published in 2025 has now confirmed what these communities have always known: Indigenous fire management is among the most effective climate solutions available.

What the Study Found

The study, published in Nature Sustainability and involving researchers from 14 countries, analyzed satellite data spanning 40 years across 27 regions where Indigenous fire management is practiced. The results showed that areas managed with traditional burning experienced 72 percent fewer catastrophic wildfires than neighboring regions where Indigenous practices had been suppressed.

'The data is unequivocal,' said Dr. Rebecca Bliege Bird, the study's lead author from Penn State University. 'Indigenous fire management is not a primitive technique. It is a sophisticated, precisely timed, ecologically informed land management system that we are only now beginning to understand scientifically.'

Cultural Knowledge as Climate Science

The study documented that Indigenous fire practitioners use a complex decision-making framework that incorporates factors such as season, humidity, wind direction, fuel moisture, animal behavior, and plant phenology — elements that Western fire ecologists are only now incorporating into their models. The result is a mosaic of burned and unburned areas that supports greater biodiversity than either unmanaged landscapes or areas subject to large, uncontrolled wildfires.

Policy Implications

The study's authors called for urgent policy changes to support Indigenous fire management, including land tenure reform, funding for Indigenous-led fire programs, and the integration of traditional knowledge into national wildfire strategies. In Australia, the Northern Territory's Indigenous fire management program has already reduced greenhouse gas emissions by an estimated 500,000 tonnes of CO2 equivalent annually.
