Thailand's Fight Against Air Pollution: Strategies And Challenges

Thailand's air pollution is a complex issue, with sources ranging from vehicular emissions in cities to industrial discharges in concentrated zones. It is a transboundary issue, impacting neighbouring countries like Myanmar and Laos, which are primarily agricultural-based. Bangkok, the capital, often makes headlines for its harmful levels of air pollution, but the problem is more severe in northern cities like Chiang Mai and Chiang Rai. Air pollution in Thailand has severe health consequences, with millions of hospitalizations and tens of thousands of deaths annually. The Thai government has implemented temporary measures such as seeding or creating artificial rainclouds to cleanse the air, but more urgent actions are needed to address the root causes of the issue, including shutting down polluting factories and transitioning to less polluting transportation options.

The Thai government is implementing measures such as cloud seeding to combat air pollution

Thailand is facing a severe air pollution problem, with the country ranking 28th among the world's most polluted countries. Bangkok, in particular, has made headlines for its hazardous levels of air pollution, although the issue is prevalent across the nation. The Thai government is implementing various measures to tackle this pressing issue, including cloud seeding to induce rainfall and clear the air of harmful pollutants.

Cloud seeding is a process where chemicals are released into the atmosphere, causing water vapour to condense and form clouds, eventually leading to rainfall. The Thai government has deployed cloud-seeding planes to address the air pollution crisis in Bangkok and other affected areas. While this method can provide temporary relief from larger particulates, it does not effectively reduce PM2.5, which are fine particles that pose significant health risks.

In addition to cloud seeding, the Thai government has taken other steps to mitigate air pollution. They have tightened restrictions on heavily polluting vehicles, deploying police and military personnel to inspect factories and incinerators, and enforcing stricter emission controls. The government has also focused on reducing traffic density in certain areas and during specific times. Additionally, they have initiated road cleaning programs, using hoses to wash away the accumulated pollution on roads and in underpasses and highways.

The government's efforts also extend to addressing the root causes of air pollution. They have increased the number of monitoring stations to detect hazardous pollution levels, although there have been concerns about the accuracy and transparency of the reported data. The Air Quality Control Program has pledged to implement emission standards for vehicles and inspection and maintenance programs to reduce emissions further.

The measures implemented by the Thai government, including cloud seeding, are crucial steps towards combating air pollution. However, as noted by experts, more urgent and long-term solutions are needed to address the complex and multifaceted nature of air pollution in Thailand. Protecting public health and the environment must be the utmost priority, even if it comes at some economic cost.

People in Thailand are raising awareness about the country's air pollution

People in Thailand are taking action to raise awareness about the country's air pollution crisis. In recent years, Thailand has faced severe air pollution, with Bangkok and the north of the country being particularly affected.

One notable individual is Ms Amata Chittasenee, a makeup artist-turned-environmentalist, who initiated a project to 'swatch' the colours of the air in Bangkok. She stuck transparent tape on various surfaces, revealing a spectrum of grey to pitch black, indicating high levels of dust in the air. Ms Amata's creative approach has helped to visually convey the severity of Bangkok's air pollution and has gained attention on social media platforms such as Instagram.

Another individual making an impact is Dr Wirun Limsawart, Director of the Society and Health Institute at the Ministry of Public Health. Dr Wirun highlights the disparity in awareness and access to protective measures between people from different socioeconomic backgrounds. He emphasises the inequity in health outcomes, where individuals from lower socioeconomic backgrounds are more vulnerable to the harmful effects of air pollution due to a lack of access to information and resources.

Additionally, Associate Professor Witsanu Attavanich, an environmental economist at Kasetsart University, has conducted research estimating the social cost of PM2.5 pollution in Thailand. His findings reveal a significant economic impact, underscoring the urgency of addressing air pollution to protect the health and well-being of the Thai population.

The people of Thailand are also taking to social media and online forums to share their experiences and concerns about air pollution. Many have expressed their worries about the visible smog, respiratory ailments, and the lack of effective government action. Some have reported instant effects such as sore throats, respiratory issues, and headaches, particularly during heavy traffic and rush hour.

While Thailand continues to develop and industrialise, it is crucial that the voices of its people are heard and that effective measures are implemented to address the country's air pollution crisis.

Air pollution in Thailand is caused by a mix of factors, including traffic, construction, and factory emissions

Thailand is the 28th most polluted country globally, according to IQ Air. The country's air pollution is caused by a mix of factors, including traffic, construction, and factory emissions.

In cities like Bangkok, air pollution is primarily caused by vehicular emissions. Data from the Pollution Control Department (PCD) shows that Bangkok's levels of PM10—particulate matter less than 10 μm in diameter—have consistently exceeded national standards over the past decade. PM10 is associated with premature mortality and various health issues, and Bangkok's hot climate and outdoor lifestyle may exacerbate its impacts.

The north of Thailand, including cities such as Chiang Mai and Chiang Rai, tends to experience worse air pollution than the capital. This is partly due to fires and agricultural burning in these regions, as well as transboundary haze from neighbouring countries like Myanmar and Laos, which primarily use slash-and-burn farming methods.

Seasonality also plays a role in Thailand's air pollution. From December to April, air quality tends to be at its worst, with people in Bangkok often resorting to wearing masks and using air purifiers. During these months, air pollution in Bangkok has reached hazardous levels, leading to the closure of schools and advisories to work from home.

While Bangkok and northern cities bear the brunt of air pollution, the issue impacts the entire country. Thailand's rapid industrialization and urbanization have led to increased vehicular emissions, construction, and factory discharges, all contributing to poor air quality. Additionally, as an agricultural country, Thailand also faces biomass burning and transboundary haze, further exacerbating the problem.

The Thai government is enforcing pollution regulations and developing long-term solutions with the UN Environment

Thailand is facing significant environmental challenges, particularly air pollution, as a result of its transition from an agricultural economy to a more industrialised one. Bangkok, the capital city, has frequently made headlines worldwide for its hazardous levels of air pollution, which have severe health consequences for residents and visitors.

The Thai government is taking action to address this issue by enforcing pollution regulations and collaborating with the UN Environment to develop long-term solutions. For instance, they have sent police and military personnel to inspect factories and incinerators, and they have also shut down schools to protect children from the harmful effects of air pollution. The government has also deployed cloud-seeding planes to induce rainfall and clear the air of pollutants, although this method has been criticised for only providing temporary relief and not reducing PM2.5 levels.

In addition to these short-term measures, the Thai government is working on more urgent initiatives, such as implementing emission standards for vehicles, inspection and maintenance programs for cars, and roadside inspections to enforce emission controls. These efforts are in line with the recommendations of Kakuko Nagatani-Yoshida, the UN Environment's Regional Coordinator for Chemicals, Waste, and Air Quality, who has acknowledged the government's progress in addressing air pollution.

Furthermore, the government has taken steps to reduce traffic density in certain areas and has implemented road cleaning with water hoses to remove thick accumulations of pollution on roads and highways. While these measures have had limited impact, they demonstrate the government's commitment to exploring various approaches to mitigate air pollution.

The Thai government's collaboration with the UN Environment is a positive step towards developing comprehensive and effective long-term solutions to the country's air pollution crisis.

Income disparities in Thailand result in unequal access to protection from air pollution

Thailand's economic growth has come at a great cost to its people and the environment. The country faces several environmental issues, with air pollution being one of the most pressing concerns. This problem is particularly acute in northern cities such as Chiang Mai, Chiang Rai, and Bangkok, where air pollution levels often exceed the World Health Organization's (WHO) recommended limits.

The Thai government's response to air pollution has been inadequate, with insufficient funds allocated to address this issue effectively. The government's budget for managing air pollution is minimal, leading to ineffective solutions. As a result, the burden of protecting oneself from air pollution falls on individuals, and the cost of protection is high. On average, individuals in Thailand spend over 18 USD (600 baht) a month on masks and protective products, amounting to 59.6 billion baht in 2018.

In contrast, high-income individuals and their families are better equipped to protect themselves from ambient air pollution. They can afford private transportation, live in healthier environments, and have the financial resources to purchase air purification devices. Their higher tax contributions may also influence their willingness to pay additional costs for improved air quality.

Community-led initiatives in certain sub-districts, such as Ping Khong, Mae Na, and Sop Pong, have become exemplars of how local initiatives can drive environmental and public health improvements. These communities have adopted sustainable practices, such as the Huai Luek Royal Project, which encourages diversified crops and discourages crop burning, thereby reducing air pollution from agricultural practices. Additionally, community-led waste management and water conservation workshops in Sop Pong have fostered a culture of conservation and addressed immediate air pollution concerns. These collective actions demonstrate the power of community involvement and innovation in creating a sustainable future.
