How the world’s fires changed while humanity hit pause

The recent study from the Chinese Academy of Sciences, published in Cell Reports Sustainability, sheds new light on the relationship between human activity and wildfire occurrences. Led by Professor Jianghao Wang, the research team analyzed data from the COVID-19 era and compared it with other years, revealing that the global lockdowns of 2020 led to a net reduction in average fire activity.

This finding is significant as it underscores the impact of human behavior, specifically reduced activity levels, on fire dynamics. While the study acknowledges the complexity of attributing fire incidents to human influence due to the interplay of natural and human factors, it provides a valuable insight into how mitigating human activity can potentially mitigate fire risks.
