Landscape fires reason for 90% pollution related deaths globally: Study

Over 90 per cent of the global deaths per year linked to air pollution from landscape fires were in low and middle-income countries, including India, according to a study published in The Lancet journal. Other countries with the highest burdens of disease due to landscape fires, including wildfires, were China, Indonesia and those in the sub-Saharan Africa. The findings highlighted geographic and socioeconomic inequalities in how landscape fires affect public health, an international team of researchers, including those from Monash University, Australia, found. Landscape fires occur in natural and built-up settings and can include both forest fires and those caused due to human activities. Most of the resulting deaths are related to the air pollution caused due to such fires, contributing to long-term cardiovascular and respiratory illnesses.
