Spending more money on firefighting won't save us, writes Robert Gray.
Canada is in the midst of a tragic fire season: five firefighters have lost their lives, there have been countless other close calls, more than 200,000 people have been evacuated from their homes and communities, and over 17 million hectares have burned with massive quantities of greenhouse gases emitted into Earth’s atmosphere. Climate scientists warn that this situation will be repeated in the future with even worse outcomes possible.
Landscape-scale fire behaviour and fire effects research conducted by fire scientists reveals the solution: landscapes that are maintained by frequent fire and contain patchworks of different ages, structure, and vegetation types are much less predisposed to large, high severity fires than landscapes that are highly continuous and stocked with dense forests and understory fuels.
To illustrate the value of mitigation at scale, we can look to a recent example from southeast B.C. In April, the ?aq’am community and City of Cranbrook teamed up with the BC Wildfire Service and local contractors to conduct a prescribed burn on 1,300 hectares of reserve and city land. The burn objectives were infrastructure protection and ecosystem health.
The belief that climate change will render all landscape interventions fruitless means that disadvantaged communities will continue to be disproportionately affected by smoke, direct fire damage, the trauma of repeated evacuations and for Indigenous communities — the ability to carry out their cultural activities on their territories.
