Following up the two questions on (1) whether we can scientifically assess the amount of haze produced in a piece of land considering intervening variables such as wind, climate and atmospheric conditions and (2) whether there is currently any methods of controlling slash-and-burn techniques, here are the sources which I had used in finding out the answers. (1) While I mentioned earlier that it is scientifically possible to measure the haze trajectory, volume and composition, it amazes me that the current studies on this is quite extensive. Here are some interesting articles... A basic guide to measure biomass burning who.int/indoorair/interventions/antiguamod21.pdf A chemical tracing model to find out composition of types of burning process. This can even go as deep as finding out peat composition. atmos-chem-phys-discuss.net/14/2773/2014/acpd-14-2773-2014.pdf Effects of wind patterns on air pollution jieas/fvolumes/vol081-5/3-5-5.pdf In-depth analysis on effects of sea-breeze meteora.ucsd.edu/~jnorris/sio209.fa09/i1520-0469-51-15-2285.pdf Interesting guide on tracking haze footprints through chemical and haze intensity proceedings.esri/library/userconf/proc04/docs/pap1485.pdf An in-depth study on effects of the distance between haze and its source areas ncbi.nlm.nih.gov/pmc/articles/PMC1890281/ A model to study smoke/haze concentration in a lab! All you need to do is model an aggregate of an hectare of peatland composition and throw it into the burner literally. fire.nist.gov/bfrlpubs/fire60/PDF/f60002.pdf (2) Here are the ways in which controlled burning is applied in Indonesia This is one of the methods used to ensure fire does not spread into conservation peatlands. The focus is on increasing the water table or water quantity in these peatlands. It helps to keep the flammable stuffs locked when surrounding areas are being burned. geog.le.ac.uk/carbopeat/media/pdf/yogyapapers/p12.pdf The ASEAN taskforce previously released a report that focuses on looking at controlled burning solutions in Indonesia. Some farmers are educated on how to use controlled burning. Given the amount of resources and knowledge, controlled burning can sometimes turn ugly and farmers cannot stop the fire by themselves. haze.asean.org/?wpfb_dl=17 Hope that helps!
