Sustainable development in amenity-based communities of the Greater Yellowstone EcosystemBergstrom, Ryan Dennis January 1900 (has links)
Doctor of Philosophy / Department of Geography / Lisa M.B. Harrington / The Greater Yellowstone Ecosystem (GYE) is a large, nearly intact ecosystem with significant protection that has often been considered an ideal location to examine coupled human-environment interactions due to the region’s complex mosaic of private and public lands, competing natural resource uses, and rapid population growth. A transition toward sustainability suggests that current societal and economic needs can be met while simultaneously maintaining the planet’s life support systems for future generations.
To facilitate sustainability transitions it is imperative that the perceptions and experiences of local communities be documented. The objective of this study was to determine how residents of amenity-driven gateway communities (West Yellowstone and Red Lodge, Montana, and Jackson, Wyoming) surrounding Yellowstone and Grand Teton national parks perceive and experience their transition toward sustainability and the challenges inherent in that transition, how those perceptions inform locally produced and extra-local policies, and how institutions influence sustainability goals. Further, this study determined which factors contribute to these perceptions, and whether they differed spatially and temporally. To meet study objectives, a mixed methods approach was implemented, including the content analysis of local newspapers and key informant interviews.
Content analysis of local newspapers was used to investigate decision maker and stakeholder priorities for the local and regional environment, economy, and communities, and to determine what actions had been taken to promote sustainability. A total of 193 articles from West Yellowstone News, 287 articles from Carbon County News, and 333 articles from Jackson Hole News & Guide for the ten year period 2000-2009, were analyzed. Specific focal topics varied among the newspapers/communities, but in general terms the most discussed topics in West Yellowstone during this time were focused on natural resources, economic development, community development, sustainability and conservation, and growth and development. The most discussed topics for Red Lodge were community development, government services, tourism and
recreation, and growth and development. The most commonly discussed topics in Jackson were natural resources, growth and development, community development, and government services.
A total of 35 semi-structured interviews were conducted with key informants in the three study communities during the summer of 2010 to allow for specific questioning and to gain additional information. Definitions of sustainability differed based on the key informant’s community, role in the community, and length of residence in the community. Overall, definitions of sustainability focused on the environment, the economy, and multi-generational or long-term thinking. The prioritization of the economy, environment, and society also differed based on community; however, there was overall recognition that each community was dependent upon the natural environment for economic vitality.
In all three study communities, dependence on tourism and recreation-based industries, the lack of a diversified economy, and continued growth and development have resulted in a disconnect between perceptions, priorities, and goals as they relate to sustainability. In addition, each community was focused on multiple goals that further complicated the fulfillment of sustainability objectives. The multi-goal orientation of study communities is reflected in the multiple visions that various decision makers and stakeholders have for the community and their futures. What is needed most is a hierarchical approach to a sustainability transition, with each community setting its own, as well as ecosystem-wide, goals, objectives, and visions.
Findings suggest that a transition toward sustainability is perceived and experienced differently based on local context. In the GYE, that context includes a tourism-based economy that is dependent upon the natural environment, a myriad of local, regional, national, and global stakeholders, and the presence of federal land agencies that are responsible for the sustainability of natural systems, freeing local communities to focus on the societal and economic dimensions of sustainability. A transition toward sustainability will be manifested differently in the Greater Yellowstone Ecosystem, and potentially other communities adjacent to protected lands, than it is other areas because of its unique milieu. While the close proximity of federal lands, including Yellowstone National Park, may complicate the sustainability discourse at times and
may, in certain instances, add additional challenges through extra-local control of change, these same federal lands may also favor a transition toward sustainability in amenity-driven gateway communities. In addition, the disparate socio-economic conditions present in study communities, as well as extra-local institutions and agencies, directly influence, and may at times further complicate, a transition toward sustainability.
This study is based on the theory that in order to successfully transition toward sustainability, a better understanding of coupled human and natural systems is critical, and because of the close couplings between human and natural systems in the Greater Yellowstone Ecosystem, and because of the unique challenges and conflicts present in the region, the GYE is an ideal location to study human-environment interactions. The use-inspired orientation of sustainability science aims to provide tangible, real-world, and place-based understanding of a transition toward sustainability. The contribution of this study to the field of sustainability science is the understanding that, while sustainability visions, goals, and objectives may be similar across a region, consideration of local contexts affecting goals and perceptions provides valuable insights that may inform sustainability pathways at local scales and, as a result, provide deeper understanding of global sustainability. One of these insights is that communities that seemingly have much in common due to their shared region, physical environmental surroundings, and history, the specific concerns to ensure place-based sustainability can show variability. Another important point from this research is that, while most depictions of sustainability are focused on three elements—the economy, society, and the environment—individuals also key in on multigenerational concerns.

Land Use Policy and Practices in Karst TerrainsFleury, Spencer 15 November 2007 (has links)
Karst topography is the result of a specific combination of geological conditions, precipitation, biota, and temperature, and is characterized by the gradual solution of the underlying bedrock and the development of underground drainage routes for surficial runoff. Many of these karst landscapes are found in urbanized areas, where the potential for anthropogenic impact is quite high. In many instances, municipalities on karst terrains choose to mitigate these impacts by implementing ordinances that place restrictions on permissible land uses near karst landforms. This dissertation asks the question: are the impacts of karst-related land use regulation on human / social systems significant enough to merit consideration during the regulation writing and implementation process? In the process of answering this question, it is hoped that a broader understanding will be developed of how land use regulations are used to control and regulate human activity on karst lands, particularly (but not exclusively) in the United States; and that the conclusions drawn from that overview might serve as the beginnings of a generally applicable framework for the development of karst regulation.

Modéliser le concept de confort dans un habitat intelligent : du multisensoriel au comportement / Modelling the concept of comfort within a smart building : from senses to behaviourGallissot, Mathieu 26 April 2012 (has links)
La notion de confort dans les habitats est une problématique majeure pour résoudre des problèmes écologiques (consommation et émissions des bâtiments), économiques (réduction de coûts d'exploitation) et sociaux (maintien et assistance à domicile) qui définissent le développement durable. Cependant, cette notion de confort est complexe, par le nombre de paramètres qu'elle intègre, paramètres à la fois humains (perception) et physiques (mesure). Notre étude vise à modéliser cette notion de confort dans un contexte d'habitat intelligent. L'habitat intelligent émerge depuis le début des années 2000, et se positionne en héritier de la domotique, bénéficiant des progrès technologiques illustrés par l'informatique ubiquitaire et l'intelligence artificielle, concepts formants l'intelligence ambiante. La première partie de notre étude consiste à définir l'habitat intelligent, en formalisant les acquis (domotique) et les problématiques de recherche, sous l'angle de la représentation de connaissances par les modèles. Notre approche du bâtiment intelligent nous à permis de définir un cadre d'interopérabilité : un intergiciel capable de concentrer les paramètres et commandes d'un environnement. Cette interopérabilité est nécessaire de par l'hétérogénéité des objets communicants qui composent un habitat : hétérogénéité des applications, des protocoles de communication, de savoir-faire et d'usages. Les travaux réalisés dans cette première partie de l'étude nous ont permis d'instrumenter une plate-forme d'expérimentation : la plateforme Domus. Ainsi, en reconstituant un appartement, et en le dotant d'objets communicants, nous avons pu mettre en œuvre, par le biais de l'interopérabilité, un environnement intelligent, environnement qui se caractérise par une forte densité d'information et une capacité de réaction. La réalisation de cette plate-forme est nécessaire pour aborder des thématiques diverses liées à l'habitat, comme le confort. En effet, l'intelligence ambiante apporte une nouvelle dimension dans ce cadre de recherche : l'ubiquité. La densité croissante de capteurs nous permet de collecter plus d'informations, non seulement sur l'environnement mais également sur l'utilisateur et son comportement, définissant ainsi une nouvelle approche du confort : le confort adaptatif. Les travaux sur l'étude du confort dans les bâtiments se focalisent sur le confort thermique. Dans nos travaux, nous avons voulu nous intéresser au confort multi-sensoriel. Celui-ci permet d'une part de prendre en compte l'ensemble des paramètres qui agrémentent un environnement (l'air, le son, la vue) mais permet également de nous intéresser aux effets sensoriels croisés que peuvent induire ces modalités sur l'occupant. Par exemple, on soupçonne la température d'éclairage (éclairage rouge/chaud, éclairage bleu/froid) d'avoir une incidence sur la perception thermique. Des expérimentations ont en effet démontré l'approche pratique et l'approche théorique de ces effets multi-sensoriels. La mise en place de notre cadre d'interopérabilité, en première partie, dans la plateforme Domus et les résultats de nos évaluations expérimentales, en seconde partie, sur le confort réalisés dans cette même plateforme, nous permettent de participer à la définition d'un « confort-mètre », qui s'appuie à la fois sur les capteurs, les objets de l'habitat et la perception des habitants. / The notion of comfort in homes is a major problem to solve environmental problems (consumption and emissions of buildings), economic (reduction of operating costs) and social (maintenance and home care) that define sustainable development. However, this notion of comfort is complicated by the number of parameters that integrates both human (perception) and physical (measurement) parameters. Our study aims to model the concept of comfort in a smart home. Smart homes emerged in the early 2000s, and are positioned as heir to home automation, benefiting from technological advances illustrated by ubiquitous computing and artificial intelligence, ambient intelligence concepts formants. The first part of this study was to define habitat intelligent, formalizing the gains (home automation) and research issues, in terms of knowledge representation by the models. Our approach to intelligent building allowed us to define a framework for interoperability: a middleware able to focus and control the parameters of an environment. This interoperability is required by the heterogeneity of communicating objects that make up a habitat: heterogeneity of applications, communication protocols, know-how and practices. This first part of the study allowed us to instrument an experimental platform: the platform Domus. Thus, by restoring an apartment, and by providing it with smart objects, we could implement, through interoperability, an intelligent environment, environment characterized by high information density and capacity reaction. The realization of this platform is needed to address various topics related to housing, such as comfort. Indeed, ambient intelligence brings a new dimension in this research framework: ubiquity. The increasing density of sensors allows us to collect more information, not only the environment but also on the user and its behavior, thus defining a new approach to comfort: Adaptive comfort. Most of the work focusing on thermal comfort, we are interested in multi-sensory comfort. This allows one hand to take into account all the parameters that enhances an environment (air, sound, sight) but also allows our attention to cross-sensory effects that can induce these terms on the occupier. For example, it is suspected the temperature light (red light / heat, light blue / cold) to affect the perception of heat. Experiments have shown the practical approach and the theoretical approach of multi-sensory effects. The results of this study will be led to participate in the definition of "comfortmeter", a tool to sense comfort for both habitat and the inhabitant.
