Prescribed burning is a useful tool for reducing risks for communities but is not the solution particularly as the climate warms and dries, the bushfire royal commission has heard.  The Royal Commission into National Natural Hazard Arrangements heard on Tuesday from three top fire analysts who said reducing fuel loads needed careful planning to ensure hazards did not actually increase if landscapes became more fire prone.  “One of the primary motivations for changing fire behaviour by manipulating fuel is to increase the potential for active suppression of the fire,” Ross Bradstock, head of the University of Wollongong’s Centre for Environmental Risk Management of Bushfires, said.  “So by reducing fire intensity, for example, and reducing the rate of spread [and] reducing ember propagation, you are increasing the chance that people can get in there and work safely and suppress the fire.”
