Air pollution in Bangkok falls to lowest level in 2020

18 provinces in Thailand’s north and northeast are being hit by a wave of smoke and air pollution as the burning season kicks in for the country’s agricultural sector. The next 2 months are the peak of the burning off season for agricultural waste as farmers prepare their land for the next crops of corn, rice and sugar and use the fires to aid the harvest of some of their crops.

With sugar cane plantations, for example, farmers choose to burn the leaves off the plant, exposing the stalks, before harvesting the profit-making stalks, saving time and money. There are mechanical ways to achieve the same result but the farmers, pushed to slender profit margins by the multinational food companies, are unable to invest and amortise the additional costs.

The levels of PM 25 micron particulate, a measure of the smoke and haze, has been at “unhealthy” levels in Chiang Rai, Phrae, Sukhothai, Phitsanulok, Tak, Phetchabun, Phayao, Nan, Chiang Mai, Lampang, Khon Kaen, Roi Et, Chaiyaphum, Ubon Ratchathani, Saraburi, Nong Khai, Nakhon Phanom and Nakhon Ratchasima.

The Pollution Control Department are now openly admitting that the major cause of the seasonal smoke is “open burning by farmers who are preparing their land”, according to the Bangkok Post. On Monday the Deputy PM Prawit Wongsuwan issued orders to prevent farmers from starting the plantation fires. You can check the result of his orders in the fire map below.

iqair.com measures the average level of PM2.5 dust in the North at between 35-85 micrograms per cubic metre (μg/m³) yesterday, considered “unhealthy”. In the Northeast, the levels ranged between 40-99μg/m³.

The Thai Pollution Control Department considers PM2.5 readings below 50μg/m³ as “safe” but the Thai standard is twice as high as what is considered safe by the World Health Organisation.

firms.modaps, the NASA satellite fire tracking service, shows the number of fires currently alight around Thailand and the concentrations in the north and north east. The fires in northern Cambodia and north east Myanmar are also contributing to the Thailand’s smog and haze, depending on which way the winds are blowing. During this time of the year, the winds are predominantly north east and light across much of Thailand. The firms.modaps feed is live, registering the fires alight at the time the screen capture was taken.

Bangkok starts off Wednesday with relatively better air quality than the past few weeks.

Owners of cars and trucks emitting an excessive amount of black smoke face a fine up to 5,000 baht. The heavy fine is an attempt to reduce air pollution in Bangkok. Along with the fine, the Department of Land Transport will also order the vehicle be suspended from use until its emission system is fixed.

According to the department, from October last year until January, 689,333 vehicles in Bangkok areas have been inspected for black smoke emissions, while 8,762 of them have been suspended from usage. Those vehicles emitting a high volume of smoke, but are under the safety standard, will receive warnings and owners are urged to check vehicle conditions and keep proper maintenance.

Vehicles with exceeding black smoke are urged to check their vehicles at the department’s certified vehicle inspection centres located around Bangkok’s outskirts, including Phutthamonthon, Romklao, and Khlong Luang areas. Motorists are also encouraged to help reduce air pollution caused by black smoke and PM2.5 particles by having their vehicles regularly serviced or alternately switching to electric or NGV-powered vehicles.

People who witness vehicles emitting black smoke can also report the authorities by calling 1584, or contact Line: @1584DLT, or via DLT GPS mobile application.

Provincial governors in Thailand’s farming areas are being told to mitigate the burning off of agri-business waste by farmers in their provinces. The annual burn-offs are the biggest cause of the December to April air pollution in Bangkok and Central Thailand which lie in the wake of the light north-easterly breezes this time of the year. The burn-offs partly co-incide with the lighter annual north-easterly monsoons.

Lt-Gen Kongcheep Tantravanich, a spokesman for Deputy PM Prawit Wongsuwan, has been one of the first to openly admit that the agri-fires are the common denominator in the capital’s annual smog woes. Over recent decades Bangkok’s Pollution Control department has trotted out any number of PR stunts, including water-spraying drones and asking temples to stop lighting josh sticks.

Now that spokesperson says that the accumulation of PM2.5 micron dust in the atmosphere… “mainly caused by outdoor burning of waste, especially on farms, combined with poor air circulation, has been posing a health risk for the past several days”.

Deputy PM Prawit has now ordered all provincial governors to send teams to warn farmers to stop the burning or face prosecution. It’s not the first order from the top directed at farmers trying to find cheap ways to get rid of agri-waste and prepare their plantations for the next crop. But, despite the ‘warnings’ in the past the practice has continued largely unenforced.

Thai farmers conduct the burn-off activities to reduce the amount of leftover materials – biowaste – like stalk tops, leaves and refuse left after the harvesting. Rice farmers also routinely burn rice stubble – the residual plant waste to prepare fields for the next season of crops.

Around 70-75% of Thailand’s sugar production is sent overseas and the country ranks second in exports just behind Brazil. It’s a big industry. The government also introduced a quota, distribution and price support system between growers and millers which has helped to artificially keep a ceiling on the export prices. Most of Thailand’s sugarcane plantations are in the Central and Northeast regions, some of them, evidenced by the fire maps, are less than 100 kilometres north of the capital.

But the Natural Resources and Environment Minister Woravut Silpaarcha is resorting to the old government narrative, repeating that officials at the Pollution Control Department will have to coordinate with the Interior Ministry and the Bangkok Metropolitan Administration to “intensify efforts to reduce emissions of PM2.5 dust from vehicles and factories”.

He’s also suggested that companies should allow employees to work from home to reduce the amount of vehicles on the city’s roads.

The Pollution Control Department is now estimating that the biomass burn-off contribution to the PM2.5 levels could vary between 24 – 38%, with the majority of it coming from sugarcane and rice burning. Most of the concentrations of agri-burning is around Northern Thailand and in the farmlands north of Bangkok. These areas also suffer considerably from the direct effects of the smoke. Fire maps also indicate that an even worse problem exists in northern Cambodia and north-west Myanmar where the burning carries on un-abated.

The Thaiger has waged a long campaign to provide fire maps and air-pollution readings over the past 3 years as evidence of the contribution of the agri-burning to Bangkok’s annual smog problem. But officials have kept beating the same drum, blaming factories, vehicle traffic and old diesel buses (which certainly need to be regulated as well but are not the main cause of the December to April haze and smog).
