| Abstract | This research aims to study the relationship between air quality and open burning behavior of local peoplein Chiang Rai Province. In the analyzing process, concentrations of Particle Matter or PM10 levels datadocumented by Pollution Control Department and the results from a field survey in 2012 were used askey parts. In addition, hotspot data obtained from MODIS Satellite System was used to represent fireoccurrence. Satellite images from Landsat 5 TM 2007 was also brought in to be compared with thesatellite images of the year 2010, the most critical year, in order to discover burned areas. Statistics ofmonthly average of PM10 and average number of hotspot occurrences from January - April in 2008 2012 were employed to compare the relationship between them. As a consequence, their patternrelationship was found to have a relatively similar trend. Moreover, by using supervised classification, thesatellite images showed that in 2007 and 2010 the burned areas in Chiang Rai were 4,340 km2 or 37.46%and 4,386 km2 or 37.86% of the total provincial area respectively. From the field survey, it was found thatmost of these areas were repeated burning sites, mainly located in the forest where agricultural burningwas normally conducted. Therefore, changing land use to minimize open burning is most likely anotherpossible option to solve the smoke haze problem in Chiang Rai. |
