8 dic 2020 · Studies have shown human ignition is to blame for 84% of all wildfires in the United States, and 97% of all those that threaten homes. Human-sparked fires always seemed more extreme, says Stijn Hantson, a fire ecologist at the University of California, Irvine, who led the new research.
17 mag 2022 · We observe significant differences in daily fire size between human-caused and lightning-caused fires during the first several days after ignition. Human fires are on average 6.5 times larger...

4 ago 2023 · Understanding regional ignition causes and socioeconomic factors associated with human ignitions is of growing policy and management interest, especially in regions where human–fire interactions may increase in frequency or severity with global climate shifts.
19 mar 2024 · Globally, nearly all wildfires start with a human ignition source – not lightning strikes or wildlife encountering power equipment. Knowing humans can be a primary cause is an example of the sort of knowledge that helps predict and prevent wildfires, a challenge that NASA and the firefighting industry are undertaking together.
To understand if and where human ignition pressure has driven large fires, we ran Pearson correlations on the number of large human-caused fires by day of year vs. the number of human-caused fires of all sizes by day of year for all ecoregions.

28 mar 2022 · Total ignition of I includes human-caused ignition (\(I_{H}\)) and natural ignition due to lightening (\(I_{N}\)), with the latter, assumed as constant in our model.
15 feb 2022 · CB fire risk transmission is strongly mediated by human development patterns as a function of human-caused ignitions, road and boundary networks, and the distribution of high-value assets...
