The Black Summer fires that ravaged Australia last year have been a brutal wake-up call to the nation to rethink the management of extreme weather events like bushfires, and develop a greater understanding of what it means to coexist with the Australian bush.
Brodie Mastrangelo is a grad who specialises in bushfire planning and design for Strategen-JBS&G, a bespoke 鈥渘o-nonsense鈥� environmental consultancy firm. When Mastrangelo saw the scale of last summer鈥檚 bushfires, he could only feel frustration.
鈥淚 felt annoyed that all of the knowledge we have on bushfire behaviour, the research and technology at our disposal haven鈥檛 been exploited. At least they鈥檝e prompted a serious look at bushfires and have provided critical data.
鈥淏ushfires will finally start getting the respect they deserve as Australia鈥檚 most devastating natural disaster.鈥�
Bushfires do play important roles in Australia鈥檚 ecosystems, but they are occurring with more frequency and intensity as the planet continues to warm. The recent 鈥樷�� stated that current disaster management strategies will be ineffective in the face of increasingly devastating fire weather, such as record high temperatures, dryness and reduced rainfall. Moreover, the royal commission revealed that 90 per cent of homes in bushfire prone areas were not built to withstand fires.
Build BAL-wise
This is where Mastrangelo comes in 鈥� he prepares bushfire management plans for subdivision and land development applications, which include a Bushfire Attack Level (BAL) assessment. BAL measures a building鈥檚 potential exposure to ember attack, radiant heat and direct flame contact.
鈥淏AL takes into account how far you are from a certain class of vegetation and what building materials and methods you therefore need when constructing a property,鈥� he explains.
鈥淭he aim is to be constructing your development within BAL-29 or lower. With a lot of these new developments in Perth and along the Swan coastal plain, your aim is to reduce the risk of your house igniting through separation from the bush and upping the specs of your house so you don鈥檛 have combustible materials facing the vegetation.鈥�
While BAL assessments form part of the Australian Standards for building construction, Mastrangelo says buildings aren鈥檛 always up to code, and there is a knowledge gap when it comes to homeowners/occupiers grasping the real threat that bushfires pose.
鈥淧eople are becoming more aware of the bushfire risk, but there are still 鈥榯ree-changers鈥� 鈥� especially people coming from the city environment 鈥� who forget or don鈥檛 understand the importance of a well maintained and prepared property in the bush.
鈥淭his problem is being exacerbated in some areas such as Busselton and Dunsborough where a large portion of properties are unoccupied or used for short-stay accommodation. When it comes to new builds, people need to take bushfire risk into consideration.鈥�
He says some of the simplest ways we can do this include following council firebreak practices, designing fire-wise gardens, attending bushfire resilience workshops and researching the wealth of information available on the internet.
鈥淭here鈥檚 really no excuse for not being prepared. If people want to live in the bush, they need to accept that there is a risk they could lose everything they have to a bushfire.鈥�
鈥淎ttitudes need to change and are changing, but perhaps not quickly enough given that climate change is likely to amplify the risk.鈥�
Fire management is everybody鈥檚 responsibility
The Australian Federal Government intends to implement most recommendations in the royal commission鈥檚 report, including the establishment of a natural disaster management agency, and the power to declare a national state of emergency.
Mastrangelo supports other findings of the report, such as the need for local government and industry to better communicate the risk of fire to prospective property buyers and more carefully consider disaster risk in future land use planning. He suggests insurance companies will likely lead the way in this step-change.
鈥淚 think the insurance industry will undergo the most growth in the near future. Premiums will increase for people living in bushfire prone areas and insurers will prepare policies with more bushfire-specific details.鈥�
When asked about the report鈥檚 recommendation to acknowledge the role of (the way Indigenous Australians manage landscapes) in mitigating large-scale bushfires, Mastrangelo says we need to be clear about its capabilities.
鈥淐ultural burning strategies won鈥檛 prevent bushfires, and that shouldn鈥檛 be the aim. The role of cultural burning is threefold: to provide a vehicle to get fire back into the landscape to improve the health of the bush; to get Indigenous people on Country and connect them to their roots; and to reduce fuels to make bushfires more manageable when they do occur.鈥�
Go bush
The Australian environment is a mercurial force: both welcoming and unforgiving, and though we may use it and benefit from it, we should never assume we can fully control it.
鈥淏e in it, understand it and appreciate it,鈥� Mastrangelo advises.
鈥淭his means not being complacent or ignorant when living in a bushfire prone area. A stint in the local bushfire brigade, volunteering with conservation groups and attending educational workshops are all fulfilling and rewarding ways to improve respect for the Australian environment.鈥�
