Social and Community Impacts of Fire

Background

Exposure to PM_2·5 from wildfire smoke during pregnancy has been implicated as a risk factor for preterm birth. We investigated this association in the prospective nationwide US Environmental Influences on Child Health Outcomes (ECHO) Cohort, focusing on prenatal wildfire PM_2·5 exposure intensity, duration, and timing.

Background

Wildfire poses an increasing threat to communities in the Western US, driven by climate change and rising human settlement in the wildland-urban interface (WUI). It is imperative that communities in fire-prone areas become “fire-adapted” to safely manage their risk.

Wildland firefighters (WLFFs) face significant brain health risks due to prolonged exposure to smoke, extreme heat, dehydration, physical exertion and irregular sleep patterns. Here, the literature is presented as a narrative review on studies that inform our knowledge on WLFF brain health.

The James M. Inhofe National Defence Authorization Act for Fiscal Year 2023 established that certain illnesses and diseases are to be deemed as proximately caused by employment in federal fire protection activities. However, cancers affecting female wildland firefighters were not included on this list and are recommended for further evaluation.

Background

Wildland firefighting requires exposure to long shifts and poor sleep, which may pose a risk to worker safety due to impaired cognitive function.

Aims

We investigated the associations between sleep, shift characteristics, and cognitive function in wildland firefighters.

Methods

Climate change and decades of fire suppression are increasing the risk of wildfire in many rural and remote communities across Canada. Yet limited research has been done to better understand how these communities experience wildfire risk.

Forests are vital life-preserving assets, essential for biodiversity, human health, climate change mitigation, and economic stability. Yet, they are increasingly threatened by forest fires, which undermine these benefits.

Highlights

• Introduced an integrated housing-economic recovery framework that links post-wildfire housing stability to local employment conditions and economic diversity.
• Demonstrated how traditional vulnerability tools like SoVI overlook hidden and dynamic vulnerabilities, especially among renters, seasonal workers, and undocumented residents.
