As this economic development continues, the landscape becomes more fragmented and communities then enact legislation to control fires. But as many of these communities have shifted to cultivating permanent fields and building more houses, roads, and villages, the use of fire has declined.
In traditional savanna cultures, people often set fires to keep grazing lands productive and free of shrubs and trees. They then compared these data sets with regional and global trends in agriculture and socio-economic development.Īcross Africa, fires collectively burned an area about half the size of the continental United States every year. The research team, led by Niels Andela of NASA’s Goddard Space Flight Center, analyzed fire data derived from the Moderate Resolution Imaging Spectroradiometer (MODIS) instruments on NASA’s Terra and Aqua satellites. The line plot shows the annual fluctuations in global burned area and the overall downward trend. Blues represent areas where the trend was toward less burning, whether natural or human-caused, while red areas had more burning.
The map above, based on data from the international research team, shows annual trends in burned area over the study period.
Scientists determined that the decline in burned area was greatest in savannas and grasslands, where fires are essential for maintaining healthy ecosystems and habitat conservation. Globally, the total acreage burned by fires declined 24 percent between 19, according to a new paper published in Science. Using NASA satellites to detect fires and burn scars from space, researchers have found that an ongoing transition from nomadic cultures to settled lifestyles and intensifying agriculture has led to a steep drop in the use of fire for land clearing and an overall drop in natural and human-caused fires worldwide.
