A report indicates that fire pollution in Indonesia led to 3,560 deaths in September, with drought and El Niño playing significant roles.

In a stark reminder of the devastating impact of environmental factors on human health, a recent report has highlighted that fire pollution in Indonesia claimed 3,560 lives in September alone 23. This grim statistic underscores the severe consequences of prolonged wildfires, which have been exacerbated by drought conditions brought on by El Niño 23.
The report also notes that nonfire pollution from urban power generation, industry, and transportation added another 1,750 deaths to the toll in September 23. This highlights the dual threat posed by both natural and man-made pollutants to public health in Indonesia.
Government efforts to combat the crisis included deploying over 72,000 people for cloud-seeding and firefighting operations, alongside the activation of over 2,100 medical personnel and the distribution of 5.3 million masks 23. These measures reflect the comprehensive approach taken by authorities to address both immediate safety concerns and long-term health impacts.
Amidst the struggle against the fires, there was a moment of celebration when rain fell, providing much-needed relief to firefighters who had been battling the blazes 1. However, the overall situation remained dire, with air pollution levels exceeding World Health Organization (WHO) annual PM2.5 thresholds by over seven times nationally, ten times in Sumatra, and an astounding twenty-four times in Kalimantan 2.
The impact of these high pollution levels was evident in the health statistics, with over 330,000 cases of acute respiratory infections recorded nationwide 2. Furthermore, the area covered by wildfires from January to September reached more than 1.9 million hectares, indicating the extensive scale of the environmental challenge faced by Indonesia 2.
Java, the most populous island in Indonesia, saw between 73% and 80% of its air pollution deaths attributed to nonfire sources, highlighting the significant contribution of urban and industrial activities to the region’s air quality issues 2.
