Adoption of sustainable forestry practices by Non-Industrial Private Forest owners in Virginia
Rasamoelina, Maminiaina Solonirina (Virginia Tech, 2008-05-09)
The concept of Sustainable Forest Management (SFM) has been promoted in the past few decades all over the world. Non-industrial private forest (NIPF) owners play an important role in that aspect in the U.S. because of their number (about 16 millions), the size of forest land under their control (about half of all forest land in the continental US), and the dynamism of their population (increasing number of new owners). This study sought to better understand how NIPF owners come to a decision for adoption (or non-adoption) of SFM practices. We developed a theoretical model combining four theories (the Value-Belief-Norm theory, the Theory of Planned Behavior, the Elaboration Likelihood Model, and the Innovation-Diffusion Process) to explain NIPF's decision making. Using multivariate analyses, we determined which elements of the developed theoretical model were significant in explaining adoption of eight groups of practices. Overall, some of the most significant predictors of adoption we identified were technical assistance, motivations for owning land and the use of a written management plan. Particular attention was also directed toward the eventual relationship between education and adoption of SFM practices and it was found that NIPF owners who attended educational programs tended to be likely adopters compared to those who did not attend any educational program. Since SFM was not limited to the US, we also analyzed the concept of SFM with the same goals as in the US, but under a completely different context (socio-cultural, economic and ecologic) in Africa, through the community-based natural resource management (CBNRM) system. We used four case studies and focused on criteria such as participation, equity (both procedural and distributive, power devolution, trust, etc) to analyze how CBNRM works on the field, what lessons to take from the cases to better ensure the goal of sustainability of the resources.
Antimicrobial Resistance Mitigation [ARM] Concept Paper
Vikesland, Peter J.; Alexander, Kathleen A.; Badgley, Brian D.; Krometis, Leigh-Anne H.; Knowlton, Katharine F.; Gohlke, Julia M.; Hall, Ralph P.; Hawley, Dana M.; Heath, Lenwood S.; Hession, W. Cully; Hull, Robert Bruce IV; Moeltner, Klaus; Ponder, Monica A.; Pruden, Amy; Schoenholtz, Stephen H.; Wu, Xiaowei; Xia, Kang; Zhang, Liqing (Virginia Tech, 2017-05-15)
The development of viable solutions to the global threat of antimicrobial resistance requires a transdisciplinary approach that simultaneously considers the clinical, biological, social, economic, and environmental drivers responsible for this emerging threat. The vision of the Antimicrobial Resistance Mitigation (ARM) group is to build upon and leverage the present strengths of Virginia Tech in ARM research and education using a multifaceted systems approach. Such a framework will empower our group to recognize the interconnectedness and interdependent nature of this threat and enable the delineation, development, and testing of resilient approaches for its mitigation. We seek to develop innovative and sustainable approaches that radically advance detection, characterization, and prevention of antimicrobial resistance emergence and dissemination in human-dominated and natural settings...
Assessing and Evaluating Recreation Resource Impacts: Spatial Analytical Approaches
Leung, Yu-Fai (Virginia Tech, 1998-02-09)
It is generally recognized that the magnitude of recreation resource impacts should be judged by their severity and spatial qualities, including extent, distribution, and association. Previous investigations, however, have primarily focused on assessing the severity of impacts, with limited examination of spatial qualities. The goal of this dissertation was to expand our understanding of the spatial dimension of recreation resource impacts and their assessment and evaluation. Two empirical data sets collected from a comprehensive recreation impact assessment and monitoring project in Great Smoky Mountains National Park provided the basis for the analyses. Three spatial issues were examined and presented as three papers, designed for journal submission. The purpose of the first paper was to improve our understanding of the dimensional structure and spatial patterns of camping impacts by means of multivariate analyses and mapping. Factor analysis of 195 established campsites on eight impact indicator variables revealed three dimensions of campsite impact: land disturbance, soil and groundcover damage, and tree-related damage. Cluster analysis yielded three distinctive campsite types that characterize both the intensity and areal extent of camping impacts. Spatial patterns and site attributes of these three campsite types and an additional group of primitive campsites were illustrated and discussed. The purpose of the second paper was to examine the influence of sampling interval on the accuracy of selected trail impact indicator estimates for the widely applied systematic point sampling method. A resampling-simulation method was developed and applied. Simulation results indicated that using systematic point sampling for estimating lineal extent of trail impact problems can achieve an excellent level of accuracy at sampling intervals of less than 100 m, and a reasonably good level of accuracy at intervals between 100 and 500 m. The magnitude of accuracy loss could be higher when the directions of loss are not considered. The responses of accuracy loss on frequency of occurrence estimates to increasing sampling intervals were consistent across impact types, approximating an inverse asymptotic curve. These findings suggest that systematic point sampling using an interval of less than 500 m can be an appropriate method for estimating the lineal extent, but not for estimating occurrence of trail impacts. Further investigations are called for to examine the generalizability of these results to other areas. The purpose of the third paper was to expand the scope of indices used for evaluating recreation resource impacts. Two specific objectives were to synthesize the recreation ecology and recreation resource management literature on the use of spatial indicators and indices, and to propose and apply selected spatial indices that are mostly lacking in the literature. Three spatial indices primarily adapted from the geography and ecology literature were proposed for application in recreation impact evaluation. Application results demonstrated that the Lorenz curve and associated Gini coefficient, and the linear nearest-neighbor analysis and associated LR ratio were effective in quantifying the spatial distribution patterns of trail impacts at landscape and trail scales, respectively. Application results of the third index, the impact association index, were less promising and require further refinements. Management implications and future directions of research were discussed in light of the findings of this dissertation. As the field of recreation ecology is emerging, this dissertation has demonstrated: (1) the value of recreation impact assessment and monitoring programs in providing data for examining the spatial dimension of impacts, and (2) the utility of spatial analytical approaches in understanding recreation impact assessment and evaluation.
Authenticity and Experience among Visitors at a Historic Village
Harvey, William Robert (Virginia Tech, 1998-08-18)
This study examines the concept of authenticity as applied at Appomattox Court House National Historical Park (ACHNHP). Based on past theoretical research, a functional definition of authenticity is used in an effort to test whether or not visitors to the park come for reasons relating to authenticity. Further analyses are used to determine the relative importance of authenticity to other motivational reasons for visiting the park, and how the level of authenticity experienced at ACHNHP affects how respondents rate the importance and performance of many park setting attributes. Using motivation for authenticity and importance/performance variables as predictors, visitor knowledge, perceptions of crowding and conflict, and overall satisfaction are assessed. The results suggest that while authenticity is important for park visitors, experience outputs are difficult to forecast because of correlation among independent variables and homogeneity of park visitors. Recommendations are made for future researchers when examining the concept of authenticity.
Behavioral scripts of urban park offenders: a rational choice perspective on influences of the park setting
Michael, Sean Edward (Virginia Tech, 1997)
This study examined the influence of Iocational factors on offender behavior in four serious and common park offenses: auto burglary, drug sales, indecent exposure by homosexual males, and robbery. Specifically, the study sought 1) to develop prototypical script(s) for each of the four study crimes, and 2) to support or contradict the influence of effort, risk and reward on offender behavior. Using the theoretical bases of opportunity, rational choice, and scripts, behavior of study offenders in 6 U.S. Park Service reservations in Washington, DC was interpreted. A case study strategy was chosen, utilizing participant observation, direct observation, archival records, physical artifacts, and interviews. Data collection occurred between January and March, 1996, with law enforcement personnel serving as the primary information source. Following qualitative analysis that relied upon pattern-matching and explanation-building, results suggested that 1) offenders follow logical sequences of behavior consistent with concept of a script, 2) offenders were found to act rationally, appearing to consider effort, risk and reward, 3) that offenders weight the importance of effort, risk and reward differently across offense types and across the different Acts of the same offense script, 4) that Iocational factors do influence the behavior of offenders, and 5) that offenders utilize Iocational factors that serve to decrease effort and risk, and increase reward.
Bringing in the Garbage: Opening a Critical Space for Vehicle Disposal Practices
Surak, Sarah Marie (Virginia Tech, 2012-04-19)
This dissertation examines the relationship among practices and policies of waste/ing and economic structures to make visible the implications of vehicle disposal policies for environmental policy and theory. Consequently, I attempt to build upon the small body of literature that is now critically engaging with waste production and resulting actions/inaction in the form of policies of management. In doing this I use waste as a lens to examine the interrelationships among environmental degradation and economic and political structures. Further, I examine these phenomena in relation to a physical object, the automobile, to add materiality to abstract notions of waste as it relates to both the political and the economic. Through vehicle recycling policies, I analyze how underlying economic structures in contemporary capitalism result in specific responses to the "problems" of waste as well as how the related responses, or "solutions" perpetuate an un-ecological industrial system which severely restricts the possibilities of making substantial change in the production of environmental harms.
Collaborative Interface Modeling of Fuel Wood Harvesting Practices: Residential NIPF Landowners of the Jefferson National Forest Wildland/Urban Interface, Montgomery County, Virginia
Fogel, Jonah Malachai (Virginia Tech, 2003-04-25)
Residential non-industrial private forest (NIPF) owners within the Wildland/Urban interface are an increasingly important forest owner demographic. An increase in rural residential land use is fragmenting historically large contiguous forestlands. Consequently resource management has become decentralized. NIPF-landowners, as the new land managers, must now be capable of creating resilient forest ecosystems at the landscape scale. To overcome this issue landowners and resource managers at all levels of decision-making (including landowners) must come to understand how social structures such as psychology, organizations, institutions, and culture are linked to behavior and the physical world. Collaborative Interface Modeling (CIM) has been created in response to an information gap that exists between the social and natural sciences at the site scale. CIM reveals the causal linkages between land use decisions and their effects allowing landowners to more closely trace and investigate their management policies, behaviors, and feelings as well as the consequences of those behaviors. A demonstration of the CIM process with residential forest landowners is conducted to evaluate the process and detect possible implications of encroaching development on the Jefferson National Forest in Montgomery County, Virginia. A focus on fuel wood collection was established because it has been noted as a potential source of negative impact. Possible implications and improvements to the CIM process are also noted.
Conceptual Development and Empirical Testing of an Outdoor Recreation Experience Model: The Recreation Experience Matrix (REM)
Walker, Gordon James (Virginia Tech, 1997-03-31)
This dissertation examines four issues, including: (a) whether outdoor recreation experiences not included in the Recreation Experience Preference (REP) scales exist; (b) whether these experiences can be categorized using a framework called the Recreation Experience Matrix (REM); (c) how well the Recreation Opportunity Spectrum (ROS) variables of activity, setting, and expertise explain the types of experiences outdoor recreationists receive; and (d) how well two new variables--primary mode and mode dependence--explain the types of experiences outdoor recreationists receive. In order to address these issues, an on-site questionnaire was distributed at Mount Rogers National Recreation Area in Virginia during October and November, 1995 A total of 410 people completed this questionnaire. Of these, 336 provided useable addresses for a follow-up mail-out questionnaire, with 169 (50.3%) actually returning it. After performing a variety of statistical analyses, it was found that: (a) some outdoor recreationists did report having non-REP experiences involving identity, cognition, absorption, and self-concept; (b) indirect support does exist for classifying outdoor recreation experiences using the REM framework; and (c) the ROS variables of activity, setting, and expertise, do explain some outdoor recreation experiences, as do the new variables of primary mode and mode dependence.
Derelict to Dynamic: Examining Socioecological Productivity of Underutilized/Abandoned Industrial Infrastructure, and Application in Baltimore, Maryland
Niland, Joseph Michael (Virginia Tech, 2018-06-25)
With over 16,500 documented vacant commercial and residential units, roughly 20 miles of abandoned rail lines, a historic loss of approximately 330,000 residents, millions of gallons of annual surface water sewage discharges, and a decade-long failed water quality consent decree - Baltimore, Maryland lies at a crux of chronic challenges plaguing America’s formerly most economically and industrially powerful cities (Open Baltimore GIS [Vacancies Shapefile], 2017; “Harbor Water Alert” Blue Water Baltimore, 2017). Impending environmental threats in the “Anthropocene” (Crutzen, 2004) and increased attention to societal injustices warrant heightened inclusivity of social and natural urban functions. Socioecological inequities are often highly conspicuous in declining post-industrial American cities such as Baltimore. Chronic social, economic, and environmental perturbations have rendered some of once critical American infrastructure outdated, underutilized, and/or abandoned. Rivers, forests, rail corridors, as well as residential and industrial building stock are in significantly less demand than when America’s industrial age shaped urban landscapes in the late nineteenth/early twentieth centuries. Compounded by insensitive traditional urban development, these phenomena jeopardize urban social and ecological function. This thesis is an examination of contemporary urban ecology concepts as a systemic approach for revitalizing socially and ecologically marginalized urban areas, with an application in West Baltimore, Maryland neighborhoods. Through an examination of socioecological dilemmas and root causes, a conceptual procedure for urban blight mitigation along the Gwynns Falls corridor is proposed. Adopting an urban green infrastructure plan offers comprehensive alternative solutions for West Baltimore’s contemporary challenges. Master plans are proposed for the Shipley Hill, Carrollton Scott, and Mill Hill neighborhoods in West Baltimore. Site scale socioecological connections are suggested for the Shipley Hill neighborhood with contextual linkages in the surrounding neighborhoods. Additionally, policy considerations are explored for revitalizing Baltimore’s most vulnerable landscapes. By transforming derelict industrial infrastructure to dynamic socioecological patches and corridors, this work aims to enhance socioecological equity and connectivity. Negative aspects of Baltimore’s contemporary urban condition such as blight, high vacancy rates, ecological damage, population decline, and other symptoms of shrinking cities are deeply rooted in a complex evolution of social, environmental, and economic management. Current challenges facing Baltimore can be directly linked to a long history, specifically including industrialization and systematic segregation of neighborhoods. As the United States entered a period of stability following the industrial revolution, domestic manufacturing dwindled, causing a once strong workforce population to leave industrial mega-cities such as Baltimore. This population exodus left behind prior workforce housing and industrial infrastructure, much of which now nonessential to Baltimore’s contemporary urban functions. Housing vacancies and abandoned infrastructure are most noticeable in Baltimore’s predominately minority neighborhoods. Historically marginalized by systematic segregation tactics, “redlined” neighborhoods largely continue to lack sufficient social and economic capital for adaptation to a transformative new era in Baltimore’s history. Disparities in these minority neighborhoods have shown lasting consequences and continue to suffer from financial, social, and ecological neglect. However, progressive urban planning processes pose significant opportunity for equitable inclusion of historically marginalized urban communities through the introduction of green infrastructure. Because socioecological disparities in Baltimore are incredibly complex, an equally complex solution is necessary to adequately alleviate symptoms of declining cities. Although much research and literature has been cited in systemic solutions aiming to address the totality of these issues, practical implication of these strategies remains limited. This thesis aims to identify primary drivers of socioecological inequity as well as recommend policy and spatial solutions to alleviate symptoms of shrinking cites specific to Baltimore.
A Discourse Analysis of Stakeholders? Understandings of Science in Salmon Recovery Policy
White, Dave D. (Virginia Tech, 2002-05-30)
The purposes of this study were to examine 1) understandings of science expressed in formal salmon recovery policy discourse; 2) rhetorical practices employed to justify or undermine claims about salmon policy 3); and patterns of understandings of science and associated rhetorical practices between social categories of actors. This research contributes to scholarship in public understanding of science, discourse studies, and natural resource policy. A constructivist discourse analysis was conducted using qualitative methods to analyze transcripts from over one hundred congressional hearing witnesses representing a wide diversity of stakeholder groups. Multiple coders organized discourses into analytic categories, achieving a final proportional agreement of 80% or greater for each category, at the finest scale of analysis. Stakeholders employed a collection of prototypical understandings of the nature of science, boundaries of science, and roles of science in decision-making. The process of science was described as impartial and ideal, a way to reduce uncertainty through consensus and peer-review, and subject to changing paradigms. Scientific knowledge was sometimes represented as "truth" and other times as tentative, and scientists were portrayed as independent and objective as well as captured and interest-driven. Witnesses described science as separate from and superior to politics and management. Testimony included descriptions of science?s role in developing decision alternatives, selecting among alternatives, and evaluating and legitimating alternatives. Stakeholders used these understandings of science to construct justifications to support their claims about salmon policy and undermine opposing claims. Science-based justifications included externalizing devices, construction of consensus, category entitlement, and extreme case formulations. Other justifications invoked local control, treaty rights, and local knowledge, or relied on interest management. This study has extended the theory and method of empirical discourse analysis, and produced a taxonomy of understandings that should be transferable to studies of similar policy settings. Additionally, conclusions from this study about differences between social groups in the presence, distribution, and frequency of expression of the discourses might be developed into propositions for further testing. Finally, the study has implications for communication about the role of science in collaborative natural resource decision-making processes.
Ecosystem Management in the USDA Forest Service: A Discourse Analysis
Predmore, Stephen Andrew (Virginia Tech, 2009-03-30)
This dissertation examines the environmental discourse of the USDA Forest Service, focusing on the language of ecosystem management (EM). A two pronged approach was employed: eleven interviews were conducted with agency executives (chapter two); thirty-three interviews were conducted with agency staff specialists and decision-makers, working at the agency's operational levels (chapter three and four). Differences between how agency executives view EM and how agency operators view EM were identified. Chapter two shows that agency executives generally believed that the process of EM is ingrained in the agency. Chapter three explores this assertion at the forest and district levels, and reveals conflicting stories concerning the current practice of EM. Agency operators explained EM as a process driven by ecological science, but also revealed an alternate planning process. The alternate planning process is driven by the agency's budget and strict employee roles. Through qualitative analysis of interviews with agency operators, a model of how agency operators construct agency planning was created. It illustrates the potential mismatch between planning focused on ecological science and an agency focused on budgets, cost-benefit calculations, and strict employee roles. The model also shows that agency operators described active and passive publics in their constructions of agency planning. Chapter four focuses on these constructs of the public, and shows how they are partly created by agency interpretations of the public involvement processes required by the National Environmental Policy Act (NEPA). In some cases, the agency applies a standard for public participation (substantive sieve) that requires publics to couch their concerns in scientific or legal terms. Publics that are able to navigate the substantive sieve are typically viewed as active publics, while those that cannot meet this standard are viewed as passive publics. A feedback mechanism was identified between constructs of the public and agency process; constructs of the public shape agency process and agency process shapes agency constructions of the public. The dissertation concludes by showing that agency focus on budgetary targets and the use of the substantive sieve can be understood as attempts to instill accountability into a decentralized agency with an ambiguous mission.
The Effectiveness of Two Interventions on Reducing Deer Feeding Behavior by Park Visitors
Hockett, Karen Sue (Virginia Tech, 2000-02-21)
Seeing wildlife in our Nation's parks is often a highlight of many visitors' trips, but close range human - wildlife interactions can have negative consequences for both wildlife and people. The purpose of this study was to evaluate the effectiveness of two interventions (fear and moral appeals) designed to reduce the feeding of deer by visitors in Shenandoah National Park by measuring changes in visitor attitudes and behavior. The study was conducted from July - September 1999 in a campground and picnic area, by placing the interventions (a small sign) on all picnic tables. Visitor attitudes and beliefs about the different components of the fear and moral appeal interventions were assessed by conducting surveys of campers under each experimental condition (control, moral appeal, and fear appeal). The impact of the interventions on behavior was tested in the picnic area by observing the responses of visitors to deer that frequently begged for food. Under current Park intervention conditions, visitors generally believe that feeding deer is not healthy for the deer. They have considerably less knowledge about potential threats to themselves from feeding deer. The fear appeal significantly changed attitudes about the risks to people (ANOVA, p=0.001). Under control conditions the majority (63%) of groups picnicking fed deer. Although the fear appeal produced an attitude change, it did not reduce feeding behavior by visitors (39% fed) as much as the moral appeal did (25% fed). The conflicting results between attitude and behavior change strongly suggest that researchers need to measure behavior and not just attitudes.
Estimation of Important Scenic Beauty Covariates from Remotely Sensed Data
Blinn, Christine Elizabeth (Virginia Tech, 2000-06-13)
The overall objective of this study was to determine if remotely sensed data could be used to model scenic beauty. Terrestrial digital images from within forest stands located in Prince Edward Gallion State Forest near Farmville, Virginia were rated for their scenic beauty by a group of students to obtain scenic beauty estimates (SBEs). Since the inter-rater reliability was low for the SBEs, they were not used in the modeling efforts. Instead, stand parameters (collected on tenth acre plots) that have been used in scenic beauty prediction models, like mean diameter at breast height (dbh), were the dependent variables in regression analyses. A color-infrared aerial photograph from the National Aerial Photography Program (NAPP) was scanned to achieve a pixel ground resolution of one meter. The digital aerial photograph was rectified and used as the remotely sensed data. Since the aerial photograph was taken in April, only conifer stands were used in the analyses. Summary statistics were obtained from a 23 by 23 window around plot locations in three images: the original image, a texture image created with the variance algorithm and a 7x7 window, and the first principal component image. The summary statistics were used as the independent variables in regression analyses. The mean texture digital number for the green band predicted the mean dbh of a plot with an R2 of 0.623. A maximum of 44.3 and 27.4 percent of the variability in trees per acre and basal area per acre, respectively, was explained by the models developed in this study. It seems unlikely that the remotely sensed forest stand variables would perform well as surrogates for field measurements used in scenic quality models.
Evaluating sustainability of community designs
Henden, Linda I. (Virginia Tech, 1996-07-05)
This thesis explores the meaning of sustainability, in both philosophical and practical terms, as it applies to community design. It clarifies the meaning of "sustainable development" and discusses the philosophies of certain landscape design paradigms associated with postmodern environmental ethics and the concept of eco-development. Information from the literature is synthesized into design goals and objectives grounded in postmodern environmental ethics and eco-development These objectives are used as criteria with which to determine the relative sustainability of selected urban fringe communities: Cerro Gordo, Oregon; The Fields of Long Grove, Illinois; Golden, Colorado; Kentlands, Maryland; Laguna West, California; Village Homes, California; and The Woodlands, Texas. In addition, the philosophies, goals, and characteristics of the community design strategies associated with each of these projects are reviewed. A rating system is developed and employed in the community design evaluation process.
An evaluation of the effectiveness of an urban environmental education program for inner city children
Dombroski, Jane Elizaabeth (Virginia Tech, 1995-04-15)
This study measured gain in environmental knowledge, attitudes, and behavioral intentions during an environmental education program for inner city children. The ten-day day camp consisted of environmental education activities implemented at local community natural areas and more distant field trip locations. Three "pencil-and-paper" tests were administered in a pretest/posttest fashion; one measuring environmental knowledge, one measuring attitudes, and another measuring behavioral intentions. Raw test scores revealed children gained in knowledge, but already possessed very positive environmentally sensitive attitudes and behavioral intentions before the program. Children exhibited little gain in knowledge, attitudes, and behavioral intentions in a statistical sense. Parents responded very favorably to the program, indicating their reasons for enrolling their children were well satisfied. A small amount of support was found suggesting that the more parents indicated they were involved with their children about the program content, the less their children learned. Moderate support was found suggesting that children learned more when their parents enrolled them to learn about nature. A small amount of support was found suggesting test scores increased as the number of previous family nature visits increased. Finally, little support was found for a positive relationship between the level of children's interest in nature and the amount they learned. It is suggested that future environmental education programs for inner city children should be long-term, helping guide children through the entire environmental education process. Future program evaluation should include a pilot test of the program and evaluation instruments and also employ a variety of assessment instruments and procedures.
An Exploration of Developed Forest Camping Experiences and Meanings in the Mount Rogers National Recreation Area
Garst, Barry Austin (Virginia Tech, 2005-05-03)
Developed forest camping has received little attention in the recreation research since the late 1960s and early 1970s. Changes in socio-demographics, technology, and the public's expectations for amenities over the past forty years suggested that the nature of the developed camping experience may have changed. Thus, the purpose of this study was to understand the modern developed forest camping experience and associated meanings and the influence of technology on developed forest camping. In-depth interviews were conducted in the Mount Rogers National Recreation Area with thirty-eight camping groups in three campgrounds which varied in their level of development. Developed forest camping experiences were described by participants as a combination of what they were doing (i.e., activities), who they were interacting with (i.e., social interaction), where they were camping (i.e., setting), and what they were feeling while they were there (i.e., psychological states/feelings). The camping experience occurred in stages and it emerged over the course of participants' trips, with emotional highs and lows. Camping was a social experience, with participants defining much of their experience in terms of who they were with. The developed camping experience was influenced by the natural environment, particularly scenic beauty and other aesthetic setting qualities. The majority of participants in this study suggested that they were able to get a nature-based experience even in highly developed camp settings in which large motor homes, televisions, and satellite dishes were common. Participants used a range of camping gear and electronics, and this technology was important to promote comfort and conveniences and for a distraction during inclement weather. The associated meanings of developed forest camping were restoration (i.e., rest, escape, and recovery), family functioning, special places, self-identity, social interaction, experiencing nature, association of God and nature, novelty, and the opportunity for children to learn. Restoration was the most commonly expressed meaning across all three campground types. The most commonly expressed life-context meanings were restoration and sharing positive family memories and stories. These family memories and stories often developed into important camping traditions. Recommendations for recreation managers, study limitations, and opportunities for future research are identified and discussed.
An Exploration of Emerging Collaborative Conservation Strategies to Support Sustainable Development in the United States
Kimmel, Courtney E. (Virginia Tech, 2011-03-22)
Completed as a series of manuscripts, this dissertation reflects four aspects of my research into the intersections of conservation and sustainable development as practiced by conservation land trusts and community landcare groups, as well as by faculty and staff at land grant universities. The first paper included in this dissertation explores "Conservation 2.0" strategies being developed and employed by land trust across the US to integrate social and economic development goals into their conservation missions. The second paper explores one of these Conservation 2.0 strategies in greater detail, in particular the support of ecological entrepreneurship by land trusts and partners they involve in "ecological entrepreneurship support networks". The third piece emerged out of five years of engaged research with Catawba Landcare as one community landcare group in the region. As a means to capture the development path and history of the organization as well as to facilitate its path forward, I developed a dynamic content management system (CMS) based website for the group, which is explained in Chapter 4. The fourth and final piece of this dissertation is a collaboratively written piece that examines the relationship between Catawba Landcare and Virginia Tech using four theoretical lenses for community capacity building, ultimately proposing one engagement strategy for land grant universities to build and strengthen social infrastructure in their neighboring communities. In total, this collection of works chronicles a larger endeavor to explore place-based sustainability and the role of institutions and civil society in constructing a more sustainable future.
Exploring Immigrant Farming Programs and Social Capital: A Mixed Method Approach to Program Evaluation
Hightower, Lisa S. (Virginia Tech, 2012-12-06)
African immigrants in the United States (U.S.) experience immense challenges in the form of poverty, unemployment, and underemployment. One strategy used by community development organizations to address these challenges is the development of farm entry programs that assist immigrants in beginning and sustaining farm operations in the United States. Organizations such as Cooperative Extension, resettlement agencies, and African mutual aid associations have developed beginning farmer programs that provide a supportive foundation for immigrant farmers to gain access to farmland, technical training, and markets. Returning to farming provides African immigrants with a series of benefits including supplemental income, food security, and social integration. Drawing upon social capital theory, this study offers a novel approach to measure the community and economic development outcomes of immigrant farming programs. In this mixed-method program evaluation, immigrant farming programs are analyzed as social networks that connect immigrants to technical training, farming resources, and community members who can provide access to markets. Data were collected through a survey of 112 agricultural educators working with immigrant farming programs across the United States. Data were also collected through case studies of a Midwestern program and a Southern program. The case studies include two focus groups and 20 interviews with individuals associated with the programs as participants, agricultural educators, and community partners. Regression tests were conducted to determine the social capital factors associated with well-being outcomes occurring through the programs. The models show that interaction outside of the program, and access to information are positively associated with well-being outcomes. Analysis of variance tests show differences between programs with African immigrant participants and programs with participants from other world regions. Programs with African immigrants tend to have more requirements to use farming resources compared to programs with immigrants from other world regions. Qualitative analysis found that female African immigrant participants have a lower levels of agency compared to male African immigrant participants. The study concludes with a discussion of recommendations for implementing and evaluating immigrant farming programs, as well as applying social capital theory to the field of agricultural education.
Governing Nature, Sustaining Degradation: An Eco-Governmental Critique of the Deepwater Horizon Disaster
Lawrence, Jennifer (Virginia Tech, 2015-10-15)
This dissertation explores the discursive production of, and response to, environmental disaster. The project is contextualized through the case of the 2010 Deepwater Horizon disaster in the Gulf of Mexico. By interrupting traditional perceptions of environmental disaster, this project frames socio-environmental disasters as a normal and increasingly experienced part of global hydrocarbon capitalism. The project purports that disaster is embedded within the current global economy and the high-]modernist ideologies that underlie it. As such, the strategies and techniques employed to respond to environmental disaster are intimately bound up within the same systemic processes that have created them in the first place. Moreover, because instrumentalist responses are quickly employed to mitigate disaster, the systemic factors productive of disaster remain concealed. Environmental disaster is thus a process of hydrocarbon capitalism rather than a product of it; as such it can, among other categories, be understood as manageable, profitable, and litigable. This research also highlights the normalization of chronic socio-environmental disaster though sensationalistic perspectives on acute disaster. This project explores the potential for resistance through artistic endeavors, highlighting how the discursive processes that construct traditional power/knowledge formations of environmental disaster might be subverted through non-traditional means. While the framework of eco-governmentality is especially useful in highlighting the problematic social relationships to nature, the project nonetheless acknowledges that counter-discourses for are likely to be appropriated by industry for the purpose of new enterprise and profit.
Identity, Intergroup Relationships, and Environmental Conflict
Hurst, Kristin Frances (Virginia Tech, 2019-05-01)
This dissertation explores strategies for addressing identity-related barriers to environmental problem-solving through the lens of two social-psychological theories: self-affirmation theory and moral foundations theory. Through one theoretical review, two online experiments and one in-lab experiment I explore, integrate and test theoretically grounded strategies for reducing the defensive information processing that can exacerbate intergroup divisions in multi-stakeholder settings. The specific objectives of this dissertation are to 1) integrate self-affirmation theory and moral foundations theory into the current knowledge about collaborative conservation (Chapter 2), 2) evaluate ways of tailoring environmental communication to better reach socially and politically diverse audiences (Chapter 3), and 3) experimentally test the effectiveness of an approach, based on self-affirmation theory, to facilitate productive discussion of complex, value-laden issues in group settings. Before presenting the results of this work, I provide a broad overview of the problem of group-based divisions in environmental conflict and the theoretical underpinnings of the dissertation (Chapter 1). Finally, I summarize the results and discuss the broader implications of the research (Chapter 5). The results of this research offer initial insights into how tools grounded in these theories can most effectively be applied to help alleviate identity-based barriers to environmental problem-solving.
