The Global Wildfire Paradox: Rising Threats, Decreasing Burned Areas
Despite a 26% global decline in burned areas over two decades, wildfire exposure has increased, especially in regions like Africa, the Americas, and Asia. Agricultural fragmentation and climate factors are key drivers. Effective wildfire management and mitigation strategies are crucial as climate change intensifies fire risks worldwide.

New research reveals a paradox in global wildfire trends: while the total area burned worldwide has declined by 26% over the past two decades, the number of people exposed to wildfires has increased by 40%, particularly in regions like Africa, the Americas, and Asia.
Despite the decline in burned areas, intense wildfires have risen, with climate change playing a significant role. The study highlights that agricultural expansion in Africa has fragmented wildland areas, reducing the spread of fires but increasing human exposure. Meanwhile, North and South America have seen a rise in uncontrollable wildfires, driven by intensifying fire weather and other human activities.
As climate change continues to intensify conditions conducive to wildfires, researchers emphasize the need for proactive wildfire management strategies. These include vegetation management, public education, and infrastructure solutions to prevent human-caused ignitions and reduce wildfire threats to human settlements.
