Reliable estimates of carbon emissions from planned and unplanned fires are required to assess the impact of smoke on the atmosphere.
This research by Dr Tina Bell and Dr Malcolm Possell, both from the University of Sydney, aimed to further develop knowledge of greenhouse gas emissions from fuel reduction fires and their potential impacts on the carbon balance of forested ecosystems.
This research, undertaken by the University of Melbourne’s Dr Gary Sheridan and Dr Petter Nyman, studied how the reduction of vegetation caused by bushfires can lead to major soil erosion. Erosion is increased with increased fire severity, increased rainfall intensity and steeper slopes. It is also likely to be greater in areas of the landscape that are normally drier.
Householders living in fire-prone bushland areas recognised the high fire danger on their doorsteps, but many may treat fuel hazard reduction as a low priority. This study explored how householders perceived the value and risks of living in or near bushland and analysed the complex mix of hazards, risk, benefit and value perceptions that influenced the way they approached fire hazard.
