Community Health and Resilience Under Rising Wildfire Smoke Exposure: A Review of Social Vulnerability and Adaptive Capacity

Exposure to wildfire smoke has been a growing public health issue with the increasing effects of climate change. The increasing frequency and severity of wildfires fueled by higher global temperatures and shifting climate change patterns have left more people exposed to smoke for longer periods. This exposure is primarily driven by fine particulate matter (PM 2.5 ) and carbon monoxide (CO) and other toxic gases, causing harmful health impacts, particularly to the respiratory system and cardiovascular system. The potential to reduce health effects is dependent on the adaptive capacity of individuals, households, and communities in anticipating, responding to, and recovering from smoke events. Social vulnerability factors, including socioeconomic status, race/ethnicity, housing quality, and healthcare access, greatly influence how well individuals or communities can prepare for and respond to the effects of wildfire smoke exposure. Although simple protective steps are often possible, more expensive solutions are usually out of reach for the most marginalized groups, showing that the ability to adapt depends on the resources people have. This review aims to analyze the convergence of wildfire smoke exposure, social vulnerability, and adaptive capacity in vulnerable communities with specific reference to approaches to building community resilience. This study adopts a narrative integrative review approach to synthesize current interdisciplinary evidence on the health impacts of wildfire smoke, associated social inequities, and adaptive capacity strategies, while introducing an integrated conceptual framework linking social vulnerability, adaptive capacity, and community resilience. The findings of this review substantiate the necessity of integrated, equity-oriented adaptation responses, such as enhanced risk communication, sustainable climate change mitigation strategies, and improved access to healthcare and infrastructure. In conclusion, strengthening community resilience to wildfire smoke requires confronting structural social inequities while simultaneously enhancing the adaptive capacity of resource-constrained communities.
