La solution est communautaire

The document examines the impact of the 2021 heat wave on five First Nations in British Columbia, highlighting how colonial housing policies increased vulnerability while community solidarity and traditional knowledge provided critical protection. It details specific regional impacts—from urban challenges in the Tsleil-Waututh Nation to the infrastructure dependencies of the Haíɫzaqv (Heiltsuk Nation)—and argues for resilience planning rooted in Indigenous rights and localized data.

• Colonial policies, specifically the Indian Act of 1876 and subsequent government control over housing in the 1940s, created systemic poverty and housing vulnerabilities, such as overcrowding and poor insulation, which increase susceptibility to extreme heat.
• The 2021 heat wave caused unprecedented temperatures in British Columbia, reaching a Canadian record of 49.6 °C on June 29, 2021, in Lytton, which contributed to the community being destroyed by fire in 21 minutes.
• Extreme heat severely disrupted Indigenous food security and sovereignty by drying up berries and fruits, killing salmon populations, and making traditional food preservation (canning and smoking) impossible due to heat and fire bans.
• Community solidarity and the cultural valuation of Elders acted as a protective buffer against heat-related mortality, enabling the deployment of informal resources and the temporary relocation of vulnerable members to cooler environments.
• The Haíɫzaqv (Heiltsuk Nation) implemented a transition from diesel and wood to electricity via heat pumps for 150 to 200 homes, reducing annual greenhouse gas emissions by five tonnes and diesel consumption by 2,000 litres per house, though this has strained the local electrical grid.
• Extreme heat impacted critical infrastructure in remote areas; for the Haíɫzaqv, high temperatures reduced air density, which limited the payload (fuel and passengers) of aircraft and hindered the delivery of vital medicines to neighboring communities.
• Traditional natural cooling methods, such as using streams and lakes, became ineffective during the 2021 event because water temperatures rose to 20-23 °C and some streams dried up completely.
