Smoke on the horizon: leveling up citizen and social science to motivate health protective responses during wildfires.

Climate change factors and expanded population growth in the Wildland Urban Interface (transition zone between human structures and undeveloped wildland) contribute to a projected increase in wildfire frequency and smoke exposure. As an unregulated source of air pollution, reducing smoke exposure represents a difficult challenge for health risk communicators. The target audience is broad with unpredictable health impacts due to spatial and temporal variability in exposure. Beyond providing information, agencies face challenges reaching affected populations, motivating behavior change, and overcoming barriers between intentions and actions (recommended health protection). The Smoke Sense citizen science project developed a smartphone app to provide an engagement, learning, and information-sharing platform. Here we draw upon previous trends in behavioral patterns and propose a synergistic approach of citizen and behavioral science that can be applied to increase understanding of health risk and motivate new habits to reduce exposure among impacted individuals. Presentation of the approach proceeds as follows: (1) we identify several core factors that contribute to an intention-action gap, (2) identify applicable social and behavioral science principles that can bridge the gap, (3) propose explicit examples focused on theoretical principles, (4) describe small-scale user preliminary feedback and examples for monitoring and evaluating impact, and (5) provide a look to the future for collaborative citizen engagement. Current health risk communication strategies often lack consideration of behavioral factors that may enhance motivation and encourage behavior change. The proposed approach aims to leverage the strengths of citizen and social science and seeks to encourage a focused 'digital community' to implement new habits in the face of unpredictable and dynamic environmental threats.
