Human Dimensions of Fire

On a dry winter morning between Christmas and New Year’s Eve 2021, the communities in Boulder County braced for the wind. The area lies at the base of the Front Range, made up of flat-topped mesas and open grasslands where creek bottoms are lined with cottonwood trees. On the outskirts of the communities are scattered homes and ranchettes. Farther east are established neighborhoods with mature landscaping and newer subdivisions sparsely planted with shrubs and ornamental hardwoods. Green corridors and trails run through the area.

Across all cases, actors spanned boundaries to perform functions including: (1) convening meetings and agreements; (2) implementing projects; (3) community outreach; (4) funding support; (5) project planning; (6) scientific expertise. These functions fostered conducive boundary settings, concepts and objects to communicate and work across boundaries, navigating challenges to implementing work on the ground. This work highlights context-specific ways to advance cross-boundary wildfire risk reduction efforts and uses a boundary spanning lens to illustrate how collective action in wildfire management evolves in different settings. This research highlights prescribed fire as a gateway for future collective action on wildfire risk, including managing naturally ignited wildfires for resource benefits and improving coordination during wildfire suppression efforts.

We synthesize insights needed to better address the long-standing challenges of innovation across disciplines to (i) promote coordinated research efforts; (ii) embrace different ways of knowing and knowledge generation; (iii) promote exploration of fundamental science; (iv) capitalize on the “firehose” of data for societal benefit; and (v) integrate human and natural systems into models across multiple scales. Fire science is thus at a critical transitional moment. We need to shift from observation and modeled representations of varying components of climate, people, vegetation, and fire to more integrative and predictive approaches that support pathways toward mitigating and adapting to our increasingly flammable world, including the utilization of fire for human safety and benefit. Only through overcoming institutional silos and accessing knowledge across diverse communities can we effectively undertake research that improves outcomes in our more fiery future.

We carried out a systematic literature review involving both a global and a case study approach (Portugal) to investigate the configuration of the social dimensions of wildfires in academic literature. We advance two interlocking claims: (i) human dimensions of wildfires are often simplified into shallow indicators of anthropogenic activities lacking social and historical grounding, and (ii) fire knowledge of Indigenous peoples and/or other forest and fire users and professionals remains overlooked. These arguments were manifest from the global-scale review and were confirmed by the case study of Portugal. The individual perceptions, memories and cultural practices of forest and fire users and professionals and the historical co-developments of fires, people and forests have been missing from wildfire research. Including and highlighting those perspectives will both add to existing knowledge and inform policies related to fire management by making them socially meaningful.

We investigate priorities and effectiveness of wildfire suppression using a novel empirical strategy that compares 1,500 historical fire perimeters with the spatial distribution of assets at risk to identify determinants of wildfire suppression efforts. We find that fires are more likely to stop spreading as they approach homes, particularly when those homes are of higher value. This effect of threatened assets persists after controlling for physical factors (fuels, landscape, and weather) using outputs from a state-of-the-art wildfire simulation tool, and the probability that fire spread will be halted is affected by characteristics of homes 1–2 km from a fire’s edge. Our results provide evidence that wildfire suppression can substantively affect outcomes from wildfires but that some groups may benefit more from wildfire management than others.

We evaluated the prominence and function of feedback loops embedded in cognitive maps—beliefs about patterns of causal relationships that drive system dynamics—elicited from a diverse cross-section of stakeholders in a fire-prone region in the U.S. West. We demonstrate that cognition of feedback loops is rare among individuals, but increasingly prominent within aggregations of cognitive maps, which underscores the importance of collaborative decision-making. Our analysis further reveals a bias toward perception of amplifying feedback loops and of loops in which management actions result in desirable outcomes, which points to areas where progress may be made in reforming wildfire risk governance.

Increasing wildfire size and severity across the western United States has created an environmental and social crisis that must be approached from a transdisciplinary perspective. Climate change and more than a century of fire exclusion and wildfire suppression have led to contemporary wildfires with more severe environmental impacts and human smoke exposure. Wildfires increase smoke exposure for broad swaths of the US population, though outdoor workers and socially disadvantaged groups with limited adaptive capacity can be disproportionally exposed. Exposure to wildfire smoke is associated with a range of health impacts in children and adults, including exacerbation of existing respiratory diseases such as asthma and chronic obstructive pulmonary disease, worse birth outcomes, and cardiovascular events. Seasonally dry forests in Washington, Oregon, and California can benefit from ecological restoration as a way to adapt forests to climate change and reduce smoke impacts on affected communities.

By mobilizing a timely and safe initial response, early detection technologies, strategic networks of fuel breaks, and Rangeland Fire Protection Associations help “minimize the bad days” on the fireline and improve suppression success on a vast and remote landscape.

Research organizations like Rocky Mountain Research Station may be able to institutionalize co-production by adjusting the way they incentivize and evaluate researchers, increasing investment in science delivery and scientific personnel overall, and supplying long-term funding to support time-intensive collaborations. These sorts of structural changes could help transform the culture of fire science so that coproduction is valued alongside more conventional scientific activities and products.

In this paper, researchers seek to address this question based on interviews with leaders engaged in the management of jurisdictionally complex wildfire incidents. They propose a multi-level framework for conceiving co-management as strategic efforts of individual actors to cooperatively manage perceived interdependencies with others through one or more formal or informal institutional arrangements. They then demonstrate the value of the proposed framework in its ability to organize a series of questions for diagnosing co-management situations within the context of jurisdictionally complex wildfires.
