Recent wildfires in Los Angeles have brought attention to the pressing need for integrated risk reduction strategies – combining land-use planning, insurance frameworks, and community preparedness.
During a webinar hosted by the Bushfire and Natural Hazards Research Australia, researchers and policymakers from Australia and the US examined the dynamics of the 2021 Palisade Fire and discussed risk management strategies applicable to the Australian context.
Dr Faraz Hedayati, lead research engineer at the US-based Insurance Institute for Business and Home Safety, provided an analysis of the event, describing how weather patterns and infrastructure contributed to the fire’s progression.
He noted that prolonged drought, dry vegetation, and wind speeds reaching 120 km/h made containment efforts difficult. These conditions accelerated the fire’s growth significantly, with 70% of the Palisade Fire’s total area burning in just 14 hours.
Hedayati identified three contributing factors in fire escalation:
One of his key findings involved the role of structure spacing, with increasing the separation between buildings to at least 12 metres reducing the likelihood of fire transmission significantly.
Australian contributors to the panel included CSIRO bushfire researcher Dr Raphaele Blanchi, National Emergency Management Agency Director Joe Buffone, and Natural Hazards Research Australia CEO Andrew Gissing.
The discussion focused on enhancing local policy through a combination of engineering standards, education programs, and spatial planning.
Blanchi, who leads a CSIRO initiative on bushfire-resilient housing, emphasised that building design alone is insufficient.
Key points raised for the Australian market included:
In a related development, the Insurance Council of Australia (ICA) responded to the Los Angeles fires in a public statement, framing them as a broader signal of increasing hazard risk.
The ICA described the LA wildfires as a reflection of growing global exposure to climate-influenced disasters. It said rising asset values and population growth in vulnerable locations compound the challenge for the insurance and reinsurance sectors.
The council reiterated the importance of proactive mitigation to help contain insurance affordability concerns.
“There is no simple solution to this problem, but as an industry that prices [risk], the most sustainable way to reduce rising pressure on insurance [premiums] is to reduce the underlying risk,” it said.
