Indigenous fire management promotes global biodiversity

A new study by a research team at the University of Waterloo found that the use of indigenous-controlled fire was interrupted at the beginning of the colonization, resulting in severe fire activity.


Researchers have shown how indigenous fire management, especially cultural burning, reduces the risk of boundary fires that can involve buildings and vegetation at the same time, and that fires are ecosystems. Human community..

Indigenous fire management is a global practice used for resource management, community protection and cultural purposes. Importantly, it has increased biodiversity and ecosystem heterogeneity across all major terrestrial biomes on Earth.

“The decline in biodiversity was associated with severe fire activity that began with the disruption of indigenous-controlled fire use at the beginning of colonization,” said research co-leader Kira Hoffman, Environmental. A recent postdoctoral fellow in the department said. The University of Waterloo is currently a postdoc co-appointed by the University of British Columbia’s Faculty of Forestry and the Barkley Valley Research Center.

“With an agency Public support For indigenous-led fire management, especially cultural burning, can restore important cultural practices while helping protect ecosystems and human communities from increasingly devastating wildfires. “

This study is about extinguishing fires for over a century. Climate changeIs causing increasingly serious wildfires and threatening biodiversity on a global scale.

A team of undergraduate and graduate students from the Trant Ecological Legacies Lab of the Faculty of Environment, Resources and Sustainability (SERS), and postdocs, conducts a review of the primary ecology literature published from 1900 to the present. did. Increased biodiversity has been reported as a result of indigenous fire management.

“As seen in Western Canada, Manitoba, and Ontario, it is becoming increasingly urgent to identify and implement human-fire interactions that support a variety of valuable social and ecological outcomes. “Changes to existing strategies,” said Andrew Trant, associate professor at SERS and co-author of a recent publication.

Although there is widespread and modern evidence of indigenous fire management, thousands of years ago practices are still being discussed in many parts of the world. Hoffman said misunderstandings about what cultural burning is could directly oppose colonialism, fear of fire out of control, and scientific evidence of fire and indigenous ecosystem knowledge. It is a necessary and healthy element of a functioning ecosystem that states that it was partly caused by a real perception of a mountain fire risk and a perceived public perception.

“Importantly, indigenous fire management continues to show the value of applying regularly controlled fires to adapt to changing environments while supporting self-sufficient practices, communities and livelihoods. I am.

Indigenous peoples make up only 5% of the world’s population, but protect about 85% of the world’s biodiversity. Stewardship Of land managed by indigenous people. This is due to the long-term and widespread relationship and dependence on fire that has been applied as a tool for landscape management for thousands of years.

The results of an open access study co-authored by Hoffman, Trent, Emma Davis and Sara Wickham were published in the journal today. Minutes of the National Academy of Sciences..
