Relationships Between Population Density and Burned Areas Around the GlobePLoS ONE A complex spatial relationship between population density and fire exists across the globe. This study looked at this relationship by comparing population density data from SEDAC’s Gridded Population of the World to burned area maps based largely on NASA MODIS satellite observations. In general it finds that in regions where climate or vegetation create conditions where fire is likely, people tend to suppress the fire, whereas in less fire-prone regions people tend to let the fire spread. In most regions of the world, increased population density initially leads to an increase in burned area but that relationship reverses at higher levels of population density. |
