Guest post by Owen Price (Senior Research Fellow, Centre for Environmental Risk Management of Bushfires, UOW)
Fire management agencies in southern Australia have increased the amount of prescribed burning in southern Australia in recent years as a strategy to reduce the risk from bushfire. One of the potential downsides of this strategy is an increase in smoke exposure to communities on the urban interface because a larger area is treated than would burn from bushfire. Planners of prescribed fires try to avoid smoke impact by modelling the likely dispersion of smoke and avoiding days when smoke will affect local communities. We know very little about the actual smoke impact from prescribed fires, especially near the fire, and the accuracy of smoke dispersal models.
