EVENT: Dialogue Forum 4 I Year 4: The Lessons Learned from PM2.5 and Right to Clean Air

A policy forum on development and environmental challenges and policies to “bridge the gap” and “connect the dots” to create one big picture for better understanding and decision-making in the society

In times when society has become widened with gaps and differences of views and opinions, one issue could be escalated into a crisis if there are no platforms available for appropriate discussion among all concerned.

The media, while informing and inspiring their audience, could also take a role in educating and facilitating the public by providing such platforms to help “bridge the gap” and “connect the dots” to create the big picture for better understanding in the society.

Realising such critical roles, Bangkok Tribune in collaboration with its partners and with the support of Konrad-Adenauer-Stiftung, Thailand Office, every month comes up with a policy forum on critical development and environmental issues under the project, Dialogue Forum.

This is to facilitate and provide a space for discussions and exchanges of dialogues and views on development and environmental issues up to the policy level both in Thailand and the Mekong region. It therefore not only bridges the gap but also connects the dots, helping forge better understanding among the parties concerned and the public at large and encourage them to make a better decision about the issues or even find common ground or seek solutions together.

PM 2.5 has increasingly become a new challenge to the country especially in the North where forest fires which usually start in mid-January pose serious impacts to people’s health. The World Health Organisation (WHO) notes that PM2.5 is a fine particulate matter with a diameter of 2.5 microns or less that is classified as carcinogenic since 2013, and along with other fine dust, they are capable of penetrating deep into the lungs, causing cardiovascular and respiratory impacts and also affecting other organs.

According to the Pollution Control Department (PCD), during the beginning of the season, between Jan 1 to Feb 15, nearly 19,000 (18,988) hotspots had occurred in the region, or a 118% increase compared to last year’s record of 8,698 already. The PM2.5 air pollution reached its peak in March, when its 24-hour concentration level rose over 500 µg/m³. The country’s safety limit stands at 50 µg/m³ and the WHO’s is recommended at 15 µg/m³.

By the end of March, over two million people since Jan 1 had had their health affected by the haze, with symptoms ranging from mild to severe effects, according to the ministry. The most notable symptoms were involved with respiratory systems, but long-term exposure could also cause chronic health problems including lung cancer, the ministry said.

At the end of the fire season, the PCD noted that the average 24-hour concentration level of PM2.5 in the North was at 63 µg/m³ or a 110% increase from last year’s 30 µg/m³. The number of days with PM2.5 beyond the safe limit stood at 112 days, or a 60% increase from last year’s 70 days, and the hotspots recorded for the whole season stood at 108,984, or a 356% increase from last year’s 23,877. 

While causes or motivations of these forest fires are varied, officials concerned have pointed out that almost all of them are human-driven, relating closely to the conventional utilisation of forests and hilly farmland by the locals to sustain their farm-based livelihoods; ranging from farmland expansion, clearing of farm residues in the fields, grazing, wildlife hunting, and collecting of forest products_all are typical to seasonal fire burning elsewhere in Southeast Asia.

The PCD chief, Dr. Pinsak Suraswadi noted that the problem was not just about PM2.5 or forest fires here. It’s actually about the unsustainable use of natural resources here and elsewhere. It’s a social and economic problem that occurs almost everywhere now and will continue on and on if we cannot address its causes or drivers clearly.

The challenge now is whether Thailand has learned this hard lesson and managed to address the true causes as well as coming up with new measures and policies to address them proportionately.
