Wildland fires are among the largest sources of atmospheric emissions in the U.S. and their relative contribution to air pollution is expected to grow as emissions from other sectors decrease. In the Southeastern U.S., prescribed fire is used extensively to reduce fuel loads and mitigate the risk of hazardous wildfire. However, the Southeast also includes one of the largest wildland-urban interfaces in the country with millions of residents living near fire‐prone areas. Here, the unaligned goals of air quality managers and prescribed fire practitioners present an important challenge. Our research group uses computational modeling and data analysis to simulate the interactions between air quality and socio-environmental systems with the aim of informing decision-making. In this presentation, I will share findings from ongoing efforts to study the links between the public health objectives of air quality engineering and the natural resources objectives of land management in the Southeastern U.S. The research finds a substantial influence of prescribed fire on pollutant concentrations in the region, with significant potential consequences on public health. These smoke impacts can affect areas with higher social vulnerability and larger fractions of African American residents. We further develop modeling approaches to compare air pollution from wild and prescribed fire, and show that the benefits of reducing wildfire severity through prescribed fire treatment can outweigh the air pollution impacts associated with burning. However, we also find important limitations in the tools most often used by fire practitioners to control smoke impacts. Finally, I will discuss assessments of public and land manager perceptions of fire and smoke in the Southeast and model-based projections of how climate change may influence prescribed fire and air pollution in the region.
Fernando Garcia Menendez is an Associate Professor in the Department of Civil, Construction, and Environmental Engineering at North Carolina State University. He uses computational modeling to explore interdisciplinary questions related to air pollution, climate change, and environmental policy. His research group’s work focuses on developing tools based on high-performance computing, uncertainty analysis, and integrated assessment modeling to simulate interactions between environmental and human systems. The primary goal of his research is to inform environmental decision-making and policy. Prior to joining NC State, he was a Postdoctoral Associate at the Massachusetts Institute of Technology. He received a Ph.D. in Environmental Engineering from Georgia Tech and completed his M.S. and B.S. degrees from Stanford and Tecnologico de Monterrey (Mexico). He is currently serving as the 2024-25 Fulbright Canada Distinguished Chair in Environmental Science at Carleton University.
