Forest Management for Public Health: Emphasizing the Role of Prescribed Burning

Advertisment

Introduction

Advertisment

Recent policy shifts are expected to increase attention and resources towards fuel treatments in the western United States. These shifts necessitate the integration of public health considerations into forest management planning. An interdisciplinary modeling framework was utilized to assess the exposure and health impacts of proposed forest management strategies in the Sierra Nevada ecoregion. The study simulated forest change, emissions tracking, and dispersion patterns, considering the impact on population-weighted PM concentrations and smoke-wave metrics.

Prescribed Burning and Public Health

Prescribed burning is a method used to mitigate extreme wildfire risk and reduce total smoke emissions. However, it may also contribute to smoke exposures in nearby communities. This study presents a methodological framework to quantify the air quality and health impacts of specific forest management strategies. According to the findings, moderate amounts of prescribed burning can decrease wildfire-specific PM2.5 exposures and reduce asthma-related health impacts. Nevertheless, the magnitude of this benefit levels off under scenarios with additional prescribed burning due to the added treatment-related smoke burdens. The paper calls for an integrated framework to conceptually link disparate but related analyses from forest ecology and public health to evaluate the ecological and human exposure and health implications of forest management scenarios.

Case Study: Central Sierra California

A case study was conducted to evaluate the smoke exposure and health impacts of six forest management scenarios under consideration for a 970,000 ha landscape in the Central Sierra California. The findings suggest that moderate amounts of prescribed burning result in the greatest smoke exposure reduction and health co-benefits, with a tapering effect as more prescribed burning is applied.

Policy Shifts and Governance

The recent policy shifts in forest management and public health integration were analyzed by conducting a policy document analysis. This investigation sought to understand how policies refer to both the anthropogenic assets involved in NCP co-production and the modes of governance affecting these. The findings identified six archetypes of governance of NCP and the anthropogenic assets underpinning their co-production.

The Multifunctionality of Forests

Forests are multi-functional entities that support human well-being by providing multiple material, non-material, and regulating nature's contributions to people (NCP). The sources of anthropogenic assets and their governance at various levels ranging from local to supra-national levels are also discussed. This multi-functionality of forests and how it is recognized by the Intergovernmental Science Policy Platform on Biodiversity and Ecosystem Service (IPBES) framework is important to the discourse of forest management and public health.

Climate Change, Forest Growth, and Adaptive Strategies

The impact of climate change on forest growth necessitates adaptive forest management strategies. Predictive modeling and machine learning techniques like random forests are instrumental in understanding and mitigating the effects of climate change on forests. The call for submissions of research articles on various subtopics related to forest ecosystems and climate change is a testament to the urgent need to understand the achievement of ecological and public health objectives through active forest management for resilient and sustainable fire-prone landscapes.

Conclusion

The study underscores the importance of understanding and implementing effective forest management strategies that both achieve ecological objectives and consider public health impacts. Moderate prescribed burning emerged as a significant strategy for reducing smoke exposure and delivering health co-benefits. However, the integration of these strategies into policy and practice necessitates further investigation and a comprehensive understanding of the multi-functionality of forests, their anthropogenic assets, and their governance. As our climate continues to change, proactive and adaptive forest management will be crucial in ensuring resilient and sustainable fire-prone landscapes.
