Abstract

Air pollution is one of the leading contributors to global mortality and disease. In the US, ambient fine particulate matter is the sixth highest mortality risk factor and the environmental risk factor with the largest attributable burden of disease by a wide margin. Wildland fires, including wildfires and prescribed fires, are the largest source of particulate matter emissions in the US. As emissions from other major sources continue to drop, fuels loads return to natural levels after decades of fire suppression, the popularity of prescribed burning grows, and wildfire intensity and frequency increase under a warmer climate, understanding the impacts of wildland fire on air quality and health will remain a critical environmental research priority. Wildland fires are a natural feature of many landscapes, where ecosystem health may depend on its occurrence. As populations and policies adapt to coexistence with fire, new air quality management strategies are needed to mitigate the impacts of smoke. Managing air pollution from wildland fires entails controlling fire activity through land management treatments, including prescribed fire, mechanical thinning, and resource objective wildfires, in a way that accounts for the externalities associated with emitted smoke. It also requires valuing the ecological benefits of fire and land management, principally hazardous wildfire risk reduction, but also ecosystem restoration, wildlife habitat enhancement, aesthetic improvement, and others. Effective air quality management also necessitates changing public perception of wildland fire and educating air quality engineers and land managers about the roles of fire and smoke in these coupled human and natural systems. The aim of my CAREER proposal is to develop a modeling and educational framework that will allow air quality management to merge public health objectives with the ecological objectives of land management. To achieve this aim I will pursue the following goals: (1) Enable wildland fire management based on potential health impacts; (2) Integrate air pollution externalities into prescribed fire management; (3) Develop integrated scenarios of fire risk, land management, and smoke impacts; (4) Change public perception of fire and smoke. These goals of this proposal will impact environmental engineering education, advance scientific understanding, and benefit society. Mitigating the impacts of wildland smoke while encouraging a sustainable fire regime is a unique environmental challenge that must be approached with new modeling methodologies. The framework developed during my early career aims to guide future wildland and air quality management by building understanding of these coupled human-natural systems and providing tools that align ecological and public health goals. We will produce new modeling algorithms, dispersion modeling ensembles of unprecedented scales, and integrated scenarios that link wildland and air quality management for the first time. This research will lay a foundation for the development of true integrated assessment models for wildland management. As the research objectives are pursed, a promising team of graduate students will be trained as independent researchers and gain specialization in modeling the interactions between coupled human and natural systems. Undergraduate and high school students will be exposed to environmental engineering research. Research findings will be shared through conference presentations, journal publications, and multiple venues in the North Carolina Triangle region. Beyond traditional science dissemination, I will lead an effort to effectively communicate our research to a broader audience, including the fire and land management community and the general public. To this end, science communication will be reinforced in undergraduate and graduate engineering preparation. An educational partnership between NC State University and the North Carolina Division of Parks and Recreation will be established. Importantly, our work will spark a necessary change in public perception

Abstract

Air pollution associated with smoke emissions from wildfires has been linked to increased mortality and morbidity. In the U.S. wildland fires have become an important source of air pollution across several regions, including the Southeast. Wildfires can elevate pollutant concentrations at affected communities well beyond safe levels. However, the episodic and unpredictable nature of wildfires makes estimates of health outcomes associated with individual fires or fire complexes difficult to attain with air quality and health effects models. The historic 2016 Southeastern U.S. wildfires offer an exceptional opportunity to quantify the impacts of wildfire smoke. This pilot study aims to produce an estimate of health effects in North Carolina associated with exposure to fine particulate matter pollution (PM2.5) from specific fire events that led to a deterioration of air quality in the state during the fall of 2016. We will calculate fire emissions based on data from an interagency incident information system and constrained by remote sensing. Regional-scale air quality modeling will be used to generate fire-impacted spatiotemporal PM2.5 concentrations fields for North Carolina. The air quality data will be related to health impacts by using a model based on epidemiological concentration-response functions for different health endpoints. The study will determine if regulatory modeling tools predict a significant impact from wildfire events on different health outcomes, including hospital admissions, asthma attacks, acute respiratory symptoms, and work loss days. An estimate of discernable effects of wildfires will strongly support larger grant applications focused on smoke exposure mitigation and larger-scale health impacts.

Southern Integrated Prescribed Fire Information System for Air Quality and Health Impacts

Sponsor: Joint Fire Science Program

Start Date: 10/01/16

End Date: 6/30/19

Abstract

This project proposal is in response to Joint Fire Science Project FON 16-1-08: Prescribed fire smoke emissions for the Southern Fire Exchange. To address the lack of a common record of prescribed fire occurrence and characteristics for the Southern U.S., we propose developing an integrated database for the Southeastern States’ prescribed burns. The system will be based on electronic burn permit records and consolidate information from alternative burn tracking systems and, when necessary, satellite products. Data will be gathered for recent years (2010-2016) in this research but the system will be designed to dynamically update the data going forward. This database will be at the heart of a unified platform that merges prescribed fire, air quality, and smoke exposure data into a single framework. The platform will offer real-time data and tools to fire and air quality managers through a web-based application, and will be available to support the development of new state-level digital management systems. Information compiled will be used to provide a consortium-level analysis of the impact of fires on air pollution, based on fire emissions and dispersion models, as well as state-of-the-science comprehensive atmospheric chemistry and transport modeling systems. Ultimately, we will assess the public health burden associated with prescribed burning in the Southern U.S. and effectiveness of smoke management programs. Involved in the proposal are Dr. Fernando Garcia Menendez of North Carolina State University, Dr. Talat Odman of the Georgia Institute of Technology, and Dr. Cassandra Johnson Gaither of the U.S. Forest Service Southern Research Station.
