Thailand is burning. The burning off of harvested crop plantations is lighting up the agricultural areas. The truth is starkly revealed in the live NASA satellite feeds which track the fires around the world.

CHART: Fires in the past 10 days around parts of Thailand – Firms.Modaps

Concentrations of the current fires can be seen in Central Thailand, north of Bangkok, parts of Isaan, north east of Bangkok, and around Chiang Mai in Northern Thailand. Notably the concentration of fires in northern Cambodia and across the north-western border in Myanmar, is also causing plenty of problems as the foreign smoke drifts across the borders. No matter what Thai officials do to enforce the rice, sugar and corn plantation burn-offs, there is little they can do about the haze drifting across the borders.

Bangkok, so close to clusters of fires, is in for a bad air pollution day anytime the light winds of the start of the year blow from the north or the east. The lack of rain adds to the problem, the annual problem, that engulfs Thailand’s capital during days between December and April, with the worst month, statistically, being March.

The alternative method of preparing for the next harvest, mechanical removal of the refuse and waste after harvesting, is both unpopular in Thailand and economically unviable for the small farmers whose margins remain thin with the multi-national buyers of their produce pushing for lower and lower prices every year.

In Chiang Mai, from January to the end of March, the locals even call it the ‘burning season’. Coupled with the hot season, the farmers in northern Thailand burn their fields to prepare land for the next harvest and also to get rid of biowastes like corn that can’t be sold in the market. It’s officially illegal to do the burn offs but the lack of enforcement leaves the problem unresolved and the smog and haze remain as predictable as the annual wet season.

Chiang Mai also has a local geographic problem which exacerbates the bad smoke pollution. The city is in a valley, surrounded by hills, trapping in the smoke and helping block any breezes that could otherwise blow it away.

For today, Bangkok’s air pollution is better than the past two days but still registering as ‘unhealthy for sensitive groups’ with city readings mostly between 140 – 170. Parts of the city, mostly south-east and south west, were registering readings above 300 in the past few days.

Air quality around Bangkok this morning is awful. Partly due to the lack of wind to blow the smog out of the area. To the south of Bangkok, Samut Prakan and Samut Sakhon, the air quality is even worse with visibility on the ground cut to less than a kilometre. You would be well advised to reduce you activities outside on a day of high air pollution in the capital. The rating by airvisual.com is ‘unhealthy’.

Readings around the inner city vary between 190 – 220. Areas to the east, including around Suvarnabhumi Airport, are higher.

A lot of the smog and smoke is flowing down from the north and north east where plantation fires rage, mostly unenforced, this time of the year, from December to May. Farmers have been told, repeatedly, to avoid buying off the waste after harvests of corn, rice and sugar cane but officials have been disinclined to enforce the laws. Many of the farmers have long-term contracts with some of Thailand’s leading agri-business conglomerates.

Bangkok and the central region can expect many more months, especially as the temperatures rise throughout February, March and April and the winds remain low as the north-easterly monsoon weakens.
