Reducing future bushfire risk : optimal strategies for fuel load reduction
Bushfires are among the most destructive natural hazards, threatening ecosystems, public health, and infrastructure. As risks intensify due to climate change, urban expansion, and land-use change, there is an urgent need for integrated and sustainable management approaches. In this study, we …

Application of multiple unmanned aircraft systems (UAS) for bushfire mitigation
… decision making phases. Currently in the case of bushfires disaster response services rely on watchtowers, manned aircraft and satellite data for information. Advances in technology such as the development of sense-and-avoid systems will soon allow Unmanned Aircraft Systems (UAS) to be flown …

Quantitative Geographic Analysis: A Cultural History of Australian Bushfire Narratives
… serialised fiction and journalistic accounts of bushfires side by side. Across the 19th century, fictional depictions of settler endurance and survival were increasingly tempered by journalistic portrayals of destruction. By the century's end, these narratives framed fire as a force that overcame …

Designing for communities in bushfire-prone situations: Redesigning the FireWatch website interface
… from satellites to provide near real-time bushfire information. FireWatch was originally built for emergency services personnel, but recent Australian state government inquiries have called for individuals, households and communities to have independent access to bushfire information. …

Spatial and temporal patterns (1973-2012) of bushfire in an arid to semi-arid region of Western Australia
… between the Murchison and Minilya Rivers, of all bushfires greater than 1 ha that were visible from Landsat satellite imagery ranging from 30 – 60m ground resolution. The data was analysed to characterise a general bushfire regime for the region which included: mean and median size of fire scars; …

Frequent or freakish? Framing bushfires in the context of climate change
… thesis explores media coverage of catastrophic bushfires in Australia across three large-circulation newspapers. It compares the ‘Black Saturday’ bushfires of February 2009 and the ‘Black Summer’ bushfire disaster of 2019-20 to discover how fire is framed within Australian newspaper outlets, and …

Radio propagation in fire environments.
… modelling and simulation methods to bushfire scenarios. Various scenarios that are problematic to radio communication are examined. Discussion and recommendations are made concerning radio communication frequency selection and considerations for propagation in fire environments.

Chemical composition and toxicity of emissions from burning five vegetation types of Western Australia under experimental combustion conditions
… impact on human health of particulate from bushfires and emphasise the importance of vegetation type on toxicological outcomes of bushfire-derived PM2.5. The EFs obtained in this study can be used in models to estimate the emissions from bushfires in Australia, particularly Western …

Visualising convective heat transfer in a propagating wildland fire
Bushfires are a large destructive natural hazard, intensified by climate change and increasing human activity into wildland areas. Accurate prediction of fire behaviour is essential for mitigation strategies and emergency response. While radiative heat transfer has traditionally been emphasized in …

The Impact of Extreme Weather Events on Mental Health in Africa: A Mixed-Methods Systematic Review
… flood (n=4), drought (n=4), extreme heat (n=1), bushfire (n=1), and multiple events (n=2). Findings included pathological outcomes with predictable symptomatology including mood disorders; trauma- and stressor-related disorders; and suicide. Additionally, conditions indicating psychological …

The effect of random and spatially explicit lightning and human-caused ignitions on simulated burn probabilities at small scales
<p>Our overall goal was to assess the difference between annual wildfire burn probability (BP) generated from simulation models using random ignitions versus spatially explicit ignitions for wildland urban interface (WUI) areas and designated wilderness in the Rocky Mountain West, and infer whether …
