ADAPTATION MEASURE 027
Wildfires occur as a natural phenomenon, but many were limited to burning the understory vegetation on a small scale. As the burning of fields and wildfires that were once practiced have been suppressed, forests have become contiguous over large areas, resulting in more large-scale wildfires.
The implementation of Noyaki (burning wildland) and cold fires is expected to reduce the number of large fires in forests and grasslands.
The effects of recent climate change are creating a need to reduce vulnerability and minimize damage from wildfires, which are becoming more frequent and potentially more severe.
Wildfire prevention measures are being implemented to " control fire with fire," such as Noyaki (burning wildland) and surface fires, with the intention of making forest ecosystems more adapted to future conditions.
In past years, Noyaki (wildland fire burning) has been conducted in the grasslands around Hiraodai for the purposes of landscape maintenance, pest control, and forest fire prevention. It is believed that burning near the firebreak on the ridge trail and then setting fires from the lower side will prevent grassland transition (forestation) and reduce the risk of large fires.
Firing of Koshimizu Gensei Kaen
The native flower gardens on the sandbar declined due to a decrease in non-intentional wildfires caused by the elimination of steam locomotives and the end of livestock grazing. Researchers and local residents then began to artificially set fires, which restored the colorful flower gardens. The scale and frequency of fire burning is adjusted annually according to weather conditions and other factors.

Cold fire by the indigenous peoples of Australia
Unlike forest fires, which burn the trunks of trees, cold fires, which burn the grass on the forest floor, have been known to indigenous Australians as a means of preventing large fires.
COOINDA successfully halved the number of large fires by reviving this method in 2010. GHG emissions from wildfires in northern Australia were reduced by 40%, and the organization conducting the fires was able to earn $80 million through an emissions trading scheme.
