Essays On The Interactions Between Land Use Natural Amenity And Wildfire Risk

It is essential to study the relationship between environmental features and human land-use activities that can provide a better understanding of human-environment interactions. In a response, this dissertation addresses the human-environment issues from different perspectives in three essays. The first essay conducts an integrated analysis to investigate the impacts of human activities and environmental features on wildfire occurrence at the Wildland-Urban Interface in a changing climate. We focus on the impacts of land use changes as measured by their density, connectivity, and mix. The conceptual model builds on a theoretical framework developed by Woodward (1987) and Neilson (1995) that characterizes the functioning mechanism of ecosystems. The empirical models identify the key factors that influence wildfires. Hypotheses are tested to demonstrate the spatial heterogeneity of human land-use impacts on wildfires. Results can inform the design of policies that aim to identify community vulnerabilities, reduce wildfire uncertainties, strengthen firewise community development, and inform future land-use decision making in response to wildfire threats. The second essay analyzes the impacts of wildfire risk on urban development. It builds on and expands the monocentric-city framework developed by Wu (2006) and Wu (2010) by introducing wildfire risk into this model. We calibrate the model and examine the urban spatial profiles changes under different assumptions of wildfire risks and natural amenities. We find that wildfire risk can take on various aspects of urban spatial profiles at a much broad scale that go beyond the fire-prone areas and affects both households and public decision sectors. Even without inconsistency in fire-zone designation policy, over-development can occur in fire-hazardous area. The third essay models the role of amenity in interregional migration and spatial distribution of economic activities. Extending the new economic geography model of Helpman (1998) by including locational amenities, we present a multi-market equilibrium framework that includes consumption, production, and trade. Results suggest that the effects of amenities are significantly affected by household preferences, trade barriers, and other regional economic characteristics. This study contributes to the amenity-driven migration literatures and informs the debate about the effect of amenities on interregional migrations and regional economic development.

The continuing encroachment of human settlements into fire-prone areas and extreme fire seasons in recent years make it urgent that we better understand both the physical and human dimensions of managing the risk from wildfire. Wildfire Risk follows from our awareness that increasing public knowledge about wildfire hazard does not necessarily lead to appropriate risk reduction behavior. Drawing heavily upon health and risk communication, and risk modeling, the authors advance our understanding of how individuals and communities respond to wildfire hazard. They present results of original research on the social, economic, and psychological factors in responses to risk, discuss how outreach and education can influence behavior, and consider differences among ethnic/racial groups and between genders with regard to values, views, and attitudes about wildfire risk. They explore the role of public participation in risk assessment and mitigation, as well as in planning for evacuation and recovery after fire. Wildfire Risk concludes with a dedicated section on risk-modeling, with perspectives from decision sciences, geography, operations research, psychology, experimental economics, and other social sciences.

During the five decades since its origin, law and economics has provided an influential framework for addressing a wide array of areas of law ranging from judicial behaviour to contracts. This book will reflects the first-ever forum for law and economics scholars to apply the analysis and methodologies of their field to the subject of wildfire. The only modern legal work on wildfire, the book brings together leading scholars to consider questions such as: How can public policy address the effects of climate change on wildfire, and wildfire on climate change? Are the environmental and fiscal costs of ex ante prevention measures justified? What are the appropriate levels of prevention and suppression responsibility borne by private, state, and federal actors? Can tort liability provide a solution for realigning the grossly distorted incentives that currently exist for private landowners and government firefighters? Do the existing incentives in wildfire institutions provide incentives for efficient private and collective action and how might they be improved?

Exploding growth along the Colorado Front Range has expanded the wildland-urban interface-the area where homes and vegetation mix. This area, known as the WUI, is at high risk of wildfires. Wildfire risk is based on both natural conditions, such as invasive species and climate change, and human development decisions that allow continued growth in fire-prone areas. This thesis examines the approaches to wildfire risk mitigation taken by six counties along the Front Range. I argue that these mitigation approaches are effective but do not tackle important aspects of the wildfire problem, including who pays and how risks continue to increase. Counties should minimize development in the WUI by adopting strong policies that incorporate the full costs of fire protection into local jurisdictional budgets and address growth management in the WUI. This requires a greater incorporation of the land-use planning process into decisions that put people and property at risk to wildfire.

The interaction between smoke and air pollution creates a public health challenge. Fuels treatments proposed for National Forests are intended to reduce fuel accumulations and wildfire frequency and severity, as well as to protect property located in the wild land-urban interface. However, prescribed fires produce gases and aerosols that have instantaneous and long-term effects on air quality. If fuels treatment are not conducted, however, then wild land fires become more severe and frequent causing worse public health and wellfare effects. A better understanding of air pollution and smoke interactions is needed in order to protect the public health and allow for socially and ecologically acceptable use of fire as a management tool. Wildland Fires and Air Pollution offers such an understanding and examines innovative wide-scale monitoring efforts (field and remotely sensed), and development of models predicting spatial and temporal distribution of air pollution and smoke resulting from forests fires and other sources.

“This comprehensive book offers a fascinating overview of how those fires are fought, and some conversation-starters for how we might reimagine our relationship with the woods.” —Bill McKibben, author of Eaarth: Making a Life on a Tough New Planet Wildfire season is burning longer and hotter, affecting more and more people, especially in the west. Land on Fire explores the fascinating science behind this phenomenon and the ongoing research to find a solution. This gripping narrative details how years of fire suppression and chronic drought have combined to make the situation so dire. Award-winning nature writer Gary Ferguson brings to life the extraordinary efforts of those responsible for fighting wildfires, and deftly explains how nature reacts in the aftermath of flames. Dramatic photographs reveal the terror and beauty of fire, as well as the staggering effect it has on the landscape.

Years of drought and decades of aggressive fire exclusion have left North American forests at high risk for future catastrophic fires. Forest settings are a magnet for recreational opportunities and for rapidly growing residential developmentputting an increasing number of citizens and their property into the path of wildfires. Recordsetting wildfires initiated the twentyfirst century and motivated the rise to prominence of wildfire on the political agenda, prompting important and farreaching new public policy initiatives. To be effective, these policies must be informed by sciencebut that requires more than just improved knowledge about the physical and biological dynamics of fire and forest ecosystems. Social values, socioeconomic factors, demographic trends, institutional arrangements, and human behavior must also be taken into consideration by the agencies and individuals responsible for wildland fire decision making. The first book to integrate the social science literature on the human dimensions of wildfire, People, Fire, and Forests reviews current studies from this broad, interdisciplinary field and synthesizes them into a rich body of knowledge with practical management implications. Chapters in the book highlight principal findings and common threads in the existing research and identify strengths and gaps. They cover such topics as public perception of wildfire risk, acceptability of fire management policies, and community impacts of wildfire. Designed to make relevant social science information more available and useful to wildfire risk managers and policy makers, People, Fire, and Forests is also intended to encourage and guide further research into wildfire. By exploringthe theoretical and methodological issues surrounding human interactions with wildfire and describing the practical implications of this research, this volume provides an essential resource for students, scholars, and professionals.

Although ecosystems, humans, and fire have coexisted for millennia, changes in geology, ecology, hydrology, and climate as well as sociocultural, regulatory, and economic factors have converged to make wildland fire management exceptionally challenging for U.S. federal, state, and local authorities. Given the mounting, unsustainable costs and difficulty translating existing wildland fire science into policy, the National Academies of Sciences, Engineering, and Medicine organized a 1-day workshop to focus on how a century of wildland fire research can contribute to improving wildland fire management. This publication summarizes the presentations and discussions from the workshop.
