Study Shows Wildland-Urban Interface Areas Have Grown by Over 35% in the Last 20 Years

“Rising Wildfire Risk in Urban Areas: How Human-Nature Interactions Impact Our Safety”

A coyote howling along The Tracks at Brea Trail in Brea, California on Sept. 21, 2024, may seem like a picturesque scene of wildlife in its natural habitat. However, this sighting is just one example of the increasing human-wildlife interactions occurring in wildland-urban interface (WUI) areas around the world.

According to new research led by environmental scientists from the Institute of Geographic Sciences and Natural Resources Research at the Chinese Academy of Sciences, the WUI areas have grown by 35.6 percent from 2000 to 2020. This surge in WUI areas has led to more contact between people and wildlife, such as coyotes and bears, as reported by Phys.org.

The expansion of WUI areas has also resulted in an increasing number of homes being destroyed by smaller, local wildfires. The authors of the research paper highlighted the risks associated with this trend, stating that the WUI represents the nexus of human-nature interactions where the risk of exposure to natural hazards like wildfires is most pronounced.

Using satellite analysis, the research team observed the increase in WUI areas globally over the course of 20 years. They found that there was an 85 percent increase from 2010 to 2020, indicating a growing pace of WUI expansion. The highest growth rates were observed in Nigeria, eastern China, and several regions of the United States.

While the low-intensity fire rate had risen inside WUI areas, high-intensity fires were more likely to occur outside these areas. This increase in vulnerability to large fires in WUI areas has raised concerns among wildfire officials and researchers.

Adrián Regos Sanz, a postdoctoral researcher with the Biological Mission of Galicia, emphasized the need for tailored fire management strategies in WUI areas to reduce vulnerability to wildfires. The study, titled “Global expansion of wildland-urban interface intensifies human exposure to wildfire risk in the 21st century,” was published in the journal Science Advances.

Overall, the research findings underscore the urgent need for implementing measures to reduce the wildland-urban interface and secure perimeters of rural and urban areas with buffer zones or open habitats to mitigate the risk of wildfires. This study serves as a wake-up call for spatial planning and highlights the importance of addressing the increasing vulnerability to future wildfires in urban areas.
