Exploratory analysis of trends in fire risk and simultaneous changes in population
Description:
Long-term trends in fire behavior and changes in population at risk Rappold AG, Peterson GC, US EPA Matt Jolly, USFS Air pollution regulations and technological advances have successfully reduced emissions of air pollutants from many anthropogenic sources in recent decades. During the same period, emissions from wildfires have increased, becoming the largest sources of air pollution in some geographic regions. In this work, we contrast long-term trends in fire risk with changes in population and emissions from all other sources of air pollution. Specifically, we examine spatial and temporal variability in the distribution of fire-weather parameters and characterize long-term trends in fire risk within wildland urban interface and by region to identify communities that have experienced rapid changes in population health vulnerability as well as the physical risk of wildland fire.
