A bushfire is one of the most terrifying natural phenomena that anyone is likely to experience in Australia. To be caught in a bushfire is to witness a true hell on earth — conditions hot enough to melt metal, heat fluxes that literally vaporise vegetation, and smoke plumes so dense they turn day into night.
The ‘fire behaviour triangle’ – topography, weather and fuel – represents the three key factors that influence how a bushfire behaves. Weaken any one of these and a bushfire becomes more manageable.
Building bushfire resilience to preserve life and property requires consideration of buildings, individuals, communities and the environment.
New molecular techniques have shown that the population dynamics of yellowfin tuna in the Pacific Ocean are not as we thought. Further application of these techniques may herald a more scientific approach to management of ocean fisheries, and help curb illegal fishing.
