Chiang mai: Hotspots have dropped sharply, but air pollution remains in the North. Warnings issued not to be complacent until the end of April.

According to Thai News Agency, Mr. Atthapol Charoenchansa, Director-General of the Department of National Parks, Wildlife and Plant Conservation, discussed the evolving wildfire situation in northern Thailand during an interview on the "Share the News" program on MCOT News FM 100.5. The region is witnessing a reduction in wildfire hotspots, particularly in Chiang Mai province, where the number of hotspots has decreased from over 500 on April 3rd to approximately 60. This marks the first time the number has fallen below 100. Despite this positive trend, areas bordering Chiang Mai and Tak, north of the Bhumibol Dam, continue to exhibit a high concentration of hotspots. Meanwhile, the PM2.5 dust problem remains a significant concern, as the accumulated dust will require time to dissipate.

The Director-General attributed the reduction in hotspots to stringent area control measures, including law enforcement, arrests, and rigorous prosecutions, which have heightened public deterrence. Additionally, the windy weather has facilitated the dispersion of dust. It is anticipated that these favorable wind conditions will persist, aiding in dust dispersion leading up to the Songkran festival on April 11-12.

However, authorities caution against complacency until after April, as the rainy season is expected to commence in May. In response to elevated air pollution levels, Chiang Mai province has designated high-risk areas and mobilized resources from multiple agencies to manage the situation.

The trend of wildfires this year mirrors that of the previous year, characterized by "fast, intense, and simultaneous outbreaks," particularly towards the end of March. The primary factor is the increased accumulation of forest fuel following successful fire control over the past 3-4 years, allowing fires to spread rapidly and produce substantial smoke when ignited.

Human activity remains the main cause of these fires, with groups exploiting forests for hunting, gathering forest products, and livestock farming across numerous communities surrounding forested areas. Allegations that officials intentionally ignited fires to secure funding have been refuted, as budget limitations and workload burdens make such claims unfounded.

To manage forest fuel, officials are employing controlled burning methods based on scientific principles during periods without dust to prevent severe forest fires from recurring. The additional budget of 556 million baht allocated for 2026 must adhere to bureaucratic procedures. This year, central government funds were unavailable due to election restrictions, necessitating adjustments to plans and reliance on departmental revenue to augment resources.

Finally, Mr. Atthapol urged the public to cooperate by refraining from all burning activities and avoiding outdoor activities in areas with high dust levels. He also encouraged immediate reporting of any illegal arson to officials, as their work is fraught with risks from wildfires, animal traps, and heatstroke. Although no officials have died thus far, some local volunteers have been affected, prompting a shift in focus towards ensuring their safety.
