Urban fire risk rises 30% in higher-income neighborhoods, analysis finds
Frequently located on hillsides and in canyons surrounded by wildlands, wealthy neighborhoods are more likely to catch fire. However, a UC Riverside study shows they are also likely to recover faster than lower-income areas.
A University of California, Riverside study reveals a 30% rise in fire risk for higher-income neighborhoods, as urban fires increasingly affect affluent areas. Unlike wildland fires, which have grown larger and more frequent, urban fires do not follow the same trend. The research, published in npj Urban Sustainability, analyzed 141 U.S. fires since 1984 and found that higher-income areas, characterized by suburban, owner-occupied developments, faced a 30% higher likelihood of fire exposure compared to lower-income neighborhoods.
The researchers discovered that a short, intense drying period in the six months prior to a fire, rather than long-term drought, was a critical factor. Post-fire recovery was slow and uneven, with only 27% of severely burned areas returning to their pre-fire temperature range within five years, and 73% failing to regain their previous vegetation levels.
Recovery was faster in higher-income areas, which experienced smaller vegetation losses. Income emerged as an important factor in both fire risk and recovery, with higher-income neighborhoods recovering more quickly and sustaining smaller vegetation losses. The study highlights the need to consider social characteristics in urban fire preparedness and response strategies.
