Fresh data from NASA and the Thai Space Agency GISTDA confirms that air pollution in northern Thailand is largely caused by forest and agricultural burning. This was revealed during the recent ASIA-AQ The Science Team meeting, where preliminary analyses were presented from measurements in Chiang Mai and other parts of the region.
Scientific evidence from NASA
During the ASIA-AQ project, which began in March 2024, NASA and GISTDA conducted extensive air measurements using both airborne and ground-based instruments. Their data indicate that forest and agricultural burning, including slash-and-burn agriculture and wildfires, is one of the primary causes of the high levels of PM2.5 particles affecting air quality in the region.
Long-term problems with air pollution
Air pollution has been a recurring problem in northern Thailand, especially during the dry season when fires are used to clear farmland. Chiang Mai and other cities in the region have been suffering from dangerously high levels of PM2.5 for several years, affecting both local residents and tourism.
Upcoming report in February 2025
The preliminary results from the ASIA-AQ project will be compiled in a joint report from NASA and GISTDA, scheduled for publication in late February 2025. The report is expected to provide further insights into how forest and agricultural burning contribute to air pollution and suggest possible measures to address the problem.
What does this mean for Thailand?
NASA's confirmation of the link between forest and agricultural burning and PM2.5 pollution could provide scientific support for new policies and measures to reduce air pollution. Governments and environmental organizations can use this research to strengthen legislation and impose stricter restrictions on fires that cause harmful emissions.
Thailand Info continues to monitor developments and will report more when NASA and GISTDA's final report is released.
Medical effects of long-term PM2.5 exposure
- Respiratory problems: Increased risk of asthma, bronchitis and other respiratory diseases.
- Cardiovascular diseases: Can lead to high blood pressure, heart attack and stroke.
- Impaired immune system: Prolonged exposure can weaken the immune system and increase the risk of infections.
- Impact on children and the elderly: Children and the elderly are particularly vulnerable to negative health effects.
- Long-term risks: Studies have linked PM2.5 to increased risk of lung cancer and other chronic diseases.
