Bushfire Resilient Land and Climate Care

February 19, 2020

In this thoughtfully written document, David Holmgren, co-originator of the permaculture concept outlines that while devastating, the recent Australian bushfires provide an opportunity to come to terms with both the legacies of colonisation and the unfolding climate emergency in ways that empower bottom up householder and community level resilience.

Here is the Executive Summary to give you a taster:

Fire is an intrinsic part of the Australian landscape. It has become more destructive since European colonisation, and over recent decades, we have experienced even greater destruction due to accelerating climate change and changes in land use. Australia could, and should, be leading the world in transitioning to a renewable energy base to reduce the root cause of the crisis.

Australian landscapes were once subject to the oldest continual land management practices through indigenous cultural burning practices; stopping these practices has left us with denser, fire-vulnerable forests. Traditional landuses of grazing and forestry that contributed to prevention and control of bushfires have declined across large areas of the country and been replaced by residential, recreational and conservation uses in recent decades that increase our vulnerability to bushfire.

Australia arguably has the best fire-fighting capacity in the world. However fuel reduction burning is currently the default land management tool in reducing fire danger. This is effective in some cases, but not in catastrophic bushfires. The season for safe fuel reduction burning is contracting. Further, burning can lead to lower-nutrient, drier soils with more fire-prone vegetation.

A strategic focus on the urban/bushland interface and rural residential areas where bushfires create the greatest economic and social havoc demands a much broader suit of land management practices than increasing already problematic fuel reduction burning:

  • A return to indigenous cultural burning practices where canopy and soil organic matter are left intact
  • Greater use of grazing animals combined with farming systems that use native pasture species, fire-retardant shelterbelts and silvopasture systems to build soil water- and nutrient-holding capacity
  • Managing fuels with chippers, slashers and groomers as well as livestock trampling.
  • A greater focus on fuel reduction through decomposition; research is needed on the role of microbes in speeding decomposition, and the effects of lost soil calcium.
  • Rehydration of landscapes, using Natural Sequence Farming and Keyline techniques, especially along water courses receiving urban storm water.
  • Protecting and managing dense areas of fire-retardant ‘novel ecosystems’ near towns and urban fringes, including non-native species such as willow.
  • The ecologically sensitive thinning of forests utilising the resultant biomass can also reduce our fossil fuel dependence through:
    – Carbon neutral Combined Heat and Power systems to generate dispatchable power at multiple scales, especially local scale.
    – As biochar – a soil amendment providing longterm carbon sequestration and improving soil water- and nutrient-holding capacity and microbial activity.

Most of these strategies are more labour-intensive than industrial-scale clearing or fuel-reduction burning so are less appealing to government decision makers but have potential to reform and reenergise community-based activity with government support.

While all these strategies have their proponents and opponents, thinning our forests to reduce fire risk and provide carbon neutral, dispatchable, renewable energy to accelerate the shift to a 100% renewable power grid is by far the most controversial. This idea is seen by most conservationists as inviting another massive degradation of our forests in the pursuit of business as usual. Building confidence that we can manage forests for our own safety and immediate needs while we protect our biodiversity drawdown carbon and kick the fossil fuel habit is a cultural challenge that requires leadership by environmentalists who understand how the legal fiction of “terra nullius” has distorted the conservation paradigm.

Whatever the hope for adaptive top down responses, households and communities need to become more self- and collectively-reliant as the capacity of centralised systems to manage escalating crises through command and control strategies declines. Community involvement is critical in managing local landscapes for reduced fire threat, especially in the urban/bushland interface. Flow-on benefits include community engagement, empowerment and resilience, and reduced costs to taxpayers. We need a reform of local laws to allow for small-scale community actions to be undertaken with minimal red tape.

At a household level, a well thought-out and practiced fire plan, and retrofits to buildings and outdoor spaces, allows for staying and defending a property as part of a resilient lifestyle that reduces the load on authorities managing mass evacuations.

This vision could bridge an increasingly polarised debate: empowering those on the libertarian right to manage land for the better; offering the green left a viable alternative for local power generation, bypassing international corporations and providing the ‘sensible centre’ a common sense way forwardto allow us to finally be at home in this land.

RetroSuburbia Bushfire Resilience Extract

This is an extract from my book RetroSuburbia: the downshifter’s guide to a resilient future, a 550 page richly illustrated manual that has become a best seller since its publication in February 2018. The production and availability of this extract as a free and sharable download is part of our response the Australian bushfire crisis of summer 2019/20.

RetroSuburbia includes 34 chapters across three fields of retrofitting action: the built, biological and behavioural. ‘Bushfire resilient design’ and ‘Household disaster planning’ are two distinct chapters in RetroSuburbia which exemplify strategies of permaculture-inspired adaption to challenging futures that simultaneously address climate change by reducing carbon emissions.

Those who are considering relocation in the light of this bushfire season will find the RetroSuburbian Real Estate Checklist a useful tool to help balance current concerns about bushfire with the myriad other factors to consider in those difficult decisions.

Bushfire resilient home, landscape and community design has been a part of permaculture from its origins in the 1970s on the urban fringe property that Bill Mollison saved from the great Hobart fires of 1967. My own focus on bushfire intensified following the Ash Wednesday fires of 1983 including the documentation of a bushfire resistant building in The Flywire House (1991/2009) and design and development of Melliodora, our 1 hectare property on the edge of Hepburn Springs where we have had a ‘stay and actively defend’ bushfire plan since 1988. Following Black Saturday (2009), my teaching and advocacy lead to writing Bushfire resilient landscapes and communities, a 52-page report to our own bushfire vulnerable community and Hepburn Shire council.

In February 2019 we had the first direct bushfire threat to Melliodora in thirty years leading to Reflections on fire. That experience had us tweaking our plans for this summer, which has been so devastating in other fire-vulnerable regions where climate change drought has been more intense.

A new essay Bushfire Resilient Land and Climate Care draws on the truths of the polarised debate between those identifying climate change as the root cause and those recognising weak or absent land management as the direct cause. It paints a vision of a resilient and re-energised Australia that could grow from small beginnings in fire-impacted and vulnerable communities at the urban/bushland interface.

As always, crisis is an opportunity for personal, household, community and national reflection to Creatively use and respond to change
