Study: Siberian Wildfires Could Kill 20,000 a Year in Japan; Team Analyzed Past Blazes to Model Effects of Air Pollution

A team of researchers has said that at least 20,000 more people will die in Japan a year due to air pollution if large-scale forest fires occur in Siberia.
The results of the research by a team from Hokkaido University, the University of Tokyo and others, published in scientific journal Earth’s Future, indicate the need for multinational efforts to prevent wildfires.
In 2003, about 20 million hectares of forests, equivalent to more than half the land area of Japan, are reported to have burned in Siberia. The research team used the results of these wildfires to estimate the amount of health problems and other issues caused by air pollution.
The research results showed that the hypothetical outbreak of large-scale forest fires that produced twice the amount of air pollutants such as fine particulate matter (known as PM2.5) as in 2003 could result in at least 20,000 more deaths per year in Japan than in a year with few forest fires.
“It shows that Japan is not immune to ‘transboundary air pollution’ caused by forest fires,” said Teppei Yasunari, associate professor of atmospheric and environmental science at Hokkaido University.
The increasing frequency and scale of forest fires due to global warming and other factors have become a global trend. Last year, wildfires in Canada caused air pollution in New York.
“It is a novel study that takes a new approach to its research,” said Keiji Kushida, professor of global environmental studies at Nihon University. “If this type of analysis is applied to other forest fires and different conditions, it will lead to more meaningful results.”
