Prescribed burning taking place in NSW.
Australia has a long and continuing history of burning in its forests to reduce fuels and maintain biodiversity. However, the debate over prescribed burning targets has been an ongoing one for almost as long as the practice has been conducted, with parties on all sides of the debate quoting evidence both for more burning or less burning.
Chair of the AFAC15 conference committee Chris Beattie (SA SES) launches the 2015 program
New venues in Adelaide will hold the annual Bushfire and Natural Hazards CRC & AFAC conference in the first week of September.
Large bushfires have the potential to alter the atmosphere and local weather. This project aims to further develop the understanding of how this occurs.
Excessive amounts of heat and moisture generated by large bushfires can affect the surrounding atmosphere, changing wind speed and creating pyroconvective (thunderstorm) clouds. These in turn can profoundly change the way a bushfire behaves. Researchers are starting to incorporate these vital elements into operational fire behaviour models.
Many buildings built before the mid-1980s are vulnerable to severe wind, with Cyclone Larry wreaking havoc on Innisfail in Queensland in 2006.
How can we ensure our houses can withstand the rigours of severe winds? New research by the Bushfire and Natural Hazards CRC is investigating the most practical ways of retrofitting older homes to withstand severe wind, and has its origins in Cyclone Tracy’s aftermath.
