Social and Community Impacts of Fire

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.

Smoke from extreme wildfires in Canada adversely affected air quality in many regions in 2023^1,2.

Increasing wildfires are causing global concerns about ecosystem functioning and services. Although some wildfires are caused by natural ignitions, it is also important to understand how human ignitions and human-related factors can contribute to wildfires.

Although half of Earth’s population resides in the wildland-urban interface, human exposure to wildland fires remains unquantified. We show that the population directly exposed to wildland fires increased 40% globally from 2002 to 2021 despite a 26% decline in burned area.

The social diversity of human populations living in or near wildfire-prone lands are an important influence on the scale at which wildfire mitigation action can occur among residential populations at increasing risk from wildfire.

Communities can face significant risk from wildfire, often compounded by climate change and legacies of industrial forest management.

Dangerous fire weather is increasing under climate change, but there is limited knowledge of how this will affect fire intensity, a critical determinant of the socioecological effects of wildfire.

The frequency, severity, and scale of extreme wildfire events is increasing globally, with certain regions such as the western United States disproportionately impacted. As attention shifts toward understanding how to adapt to and recover from extreme wildfire, there is a need to prioritize where additional research and evidence are needed to inform decision-making.

Existing research indicates that NGOs can serve important roles during recovery from wildfires and other hazard events. Yet less work explores the specific, place-based conditions that influence NGO participation in the recovery process, or the specific tactics they might use when facilitating the transfer of knowledge and resources that meet emergent recovery needs.

Background: In collaborative governance, many of the factors that give rise to the need for collaboration are also identified by scholars as undermining its effectiveness. Complex task environments mean that multiple and varied interests are necessary to address problems, but this inherent pluralism may also increase conflict. This suggests a pluralism paradox.
