Study Reveals How Global Wildfires Shifted During COVID-19 Lockdowns

A comprehensive study published in Cell Reports Sustainability, led by Chinese Academy of Sciences professor Jianghao Wang, has shed light on how human behavior directly influences global wildfire patterns. By comparing data from the 2020 COVID-19 lockdowns with historical records, researchers examined periods when human activity paused worldwide.

The findings indicate that lower human mobility and reduced intervention during lockdowns had the net effect of lowering average fire activity. The research provides a critical framework for untangling anthropogenic factors from meteorological conditions in wildfire risk assessment.
