正文(英文) | People are starting almost all the wildfires that threaten U.S. homes, according to an innovative new analysis combining housing and wildfire data. Through activities like debris burning, equipment use and arson, humans were responsible for igniting 97% of home-threatening wildfires, a University of Colorado Boulder-led team reported this week in the journal Fire. Moreover, one million homes sat within the boundaries of wildfires in the last 24 years, the team found. That's five times previous estimates, which did not consider the damage done and threatened by small fires. Nearly 59 million more homes in the wildland-urban interface lay within a kilometer of fires. "We have vastly underestimated the wildfire risk to our homes," said lead author Nathan Mietkiewicz, who led the research as a postdoc in Earth Lab, part of CIRES at the University of Colorado Boulder. "We've been living with wildfire risk that we haven't fully understood." To better understand wildfire trends in the United States, Mietkiewicz, now an analyst at the National Ecological Observatory Network, and his colleagues dug into 1.6 million government spatial records of wildfire ignition between 1992 and 2015; Earth Lab's own compilation of 120,000 incident reports; and 200 million housing records from a real estate database from Zillow. Among their findings:
"Our fire problem is not going away anytime soon," said co-author Jennifer Balch, director of Earth Lab, a CIRES Fellow, and associate professor of geography. It's not just that we're building more homes in the line of fire, she said, but climate change is creating warmer, drier conditions that make communities more vulnerable to wildfire. The new study, she said, does provide guidance for policy makers. "This provides greater justification that prescribed burns, where safe, can mitigate the risk and threat of future wildfires," Balch said. And we need to construct more fireproof homes in these beautiful, but flammable landscapes, she added. "We essentially need to build better and burn better." "Smokey Bear needs to move to the suburbs," Mietkiewicz concluded. "If we can reduce the number of human-caused ignitions, we will also reduce the amount of homes threatened by wildfires."
