Air Pollution

Smoke from plantation fires continues to choke central and northern Thailand

Smoke from fires, mostly deliberately lit, continue to choke sections of central and northern Thailand today. Light winds are not blowing away the smog and haze produced by the smoke, particularly in the north where Chiang Mai and Chiang Rai have readings today from ‘unhealthy’ too ‘very unhealthy’ – in a range from 170 up to 240 (particles of PM2.5 microns per cubic metre of air).

Chiang Mai’s air quality is the 2nd worst in the world today, as measured by, beaten only by the perennially bad air quality choking Dhaka in Bangladesh.

The satellite heat maps clearly indicates hundreds of deliberately lit fires in neighbouring Myanmar, and areas of central Thailand and Cambodia which are the source of the smoke haze impacting the northern cities and towns.

Whilst Bangkok’s air quality has improved in and directly around the capital – from ‘unhealthy’ on Wednesday to ‘unhealthy for some individuals’ today – there is still plenty of smoke descending on the provinces directly north of the capital today.

Most of Bangkok’s public schools, under the administration of the Bangkok Metropolitan Authority, were closed on Wednesday until today. Students will be returning on Monday after their two day enforced ‘holiday’.

The government maintains that it is cracking down on the deliberately lit plantation and farm fires where farmers burn-off the remnants of the crops (as in the case of sugar, corn and some fruits), or prepare the areas (in the case of rice). But, in reality, there appears to be little or no reductions in the number of fires being lit in farming areas around Thailand.

The agricultural machinery to make these soil preparations and clearances is expensive and not readily available for the farmers. Driven by concerns over price, the farmers opt for the cheapest means possible – incinerating areas and producing enormous fires and smoke that can last for days.

Meanwhile, even if the Thai authorities are able to reduce the number of fires lit within its own borders, the satellite fire maps clearly indicates the hundreds of similar fires lit in neighbouring Myanmar and Cambodia, where Thai authorities have no control.

    Its not the sugar cane garvest residue that is burnt, the sugar cane field is burnt before harvest to facilitate easier thus cheaper cane harvesting costs, compared to harvesting unburnt cane, to increase profits. Its the cane harvesting machines that are very expensive, not ground preparation machines. There is no valid reason to burn rice paddy debris prior to ploughing the ground for rice planting, burning is done to make minimum increase in profits. Mono cropping rice and corn can lead to deseased fields and farmers try to protect against this by burning to increase profits. This burning is not justified. Rice stubble can interfere a little with efficient land ploughin, add to ploughing costs thus reduce profit. Burning is not justified. Tractor drawn ploughs and cultivators are used for ground preparation for rice, corn and can, these machines are not that expensive. Cane harvesting machine are relatively expensive but also hugely labour saving so they are a profitable.
