Regarding global terrestrial area as a whole, wildfire trends vary depending on the time period of analysis. From 1900 to 2000, global average fire frequency, based on field data, increased 0.4% but the change was not statistically significant . Fire frequency increased on one-third of global land, mainly from burning for agricultural clearing in Africa, Asia and South America, slightly less than the area of fire frequency decrease, mainly from fire suppression across Australia, North America and Russia . Analyses of the Global Fire Emissions Database document shows that, from 1996 to 2015, global burned area decreased at a rate of -0.7% yr1  but the change was not statistically significant . From 1998 to 2015, global burned area decreased at a rate of -1.4 + 0.5% yr1 . The area of fire increases was one-third of the area of decreases, due to reduced vegetation cover from agricultural expansion and intensification  and from increased precipitation (Forkel et al.,
