A quick call to tourist police suggests they haven't yet received the memo regards a 5000THB reward

Agree with above I was here in C Rai in 2007 and while my valley near Mekhong as some breeze te situation towards Mae Sai is dire and as noted major road works make the local "dust'issue even worse.

It seeems carrot "education" wont work

Well i guess folks understand fines or removal of proerty,subsidy etc

One tambol one fire inspector .

With satelite imagery not hard to see that while cross bordr co-operation is helpful much of the problem is here.

Health campaigns re drink driving and smoking have been introduced,I trust the authorities may start this process.

However I am sure this will not be the last time it happens.

This is to be feared. But it might become less severe if there is more publicity. - With satellite imagery it is indeed not too difficult to find any fire. Here are some screenshots from FIRE MAPPER, Chiang Rai area past 24h to the last 7 days.

And to 'canopy ... Just two years ago Chiang Rai had a PM10 of 260 (20% higher than now) and Mae Hong Son had a PM10 over 500 which is off the scale of the danger level. It's bad every year, some worse than others.'

OK. The air pollution depends on place, time of the day, wind ... But, should we remain silent?

I wasn't here in February-March 2007. But winter 2012 is really bad.
