After excluding self-citations, the remaining citations (33.6 percent) filtered out into other geography education journals and were classified into three groups: splash, wave, and ripple. Although the Journal of Geography in Higher Education generated the largest in-degree count, it shared the lead with the International Research in Geographical …


The King And The Land: A Geography Of Royal Power In The Biblical World, Stephen C. Russell Jan 2017

The King And The Land: A Geography Of Royal Power In The Biblical World, Stephen C. Russell

Publications and Research

The King and the Land offers an innovative history of space and power in the biblical world. Stephen C. Russell shows how the monarchies in ancient Israel and Judah asserted their power over strategically important spaces such as privately-held lands, religious buildings, collectively-governed towns, and urban water systems. Among the case studies examined are Solomon's use of foreign architecture, David's dedication of land to Yahweh, Jehu's decommissioning of Baal's temple, Absalom's navigation of the collective politics of Levantine towns, and Hezekiah's reshaping of the tunnels that supplied Jerusalem with water.

By treating the full range of archaeological and textual evidence …


Climate Change (Mal)Adaptation As Governmentality: The Case Of The Ada Sea Defense System In The Volta River Delta Of Ghana, Kwame Ntiri Owusu-Daaku Jan 2017

Climate Change (Mal)Adaptation As Governmentality: The Case Of The Ada Sea Defense System In The Volta River Delta Of Ghana, Kwame Ntiri Owusu-Daaku

Theses and Dissertations

River deltas are complex natural environments that represent a confluence of many physical, biological and human processes vulnerable to the impacts of climate change. The likely biophysical impacts of climate change on deltas have received substantial attention. However, relatively little attention has been paid to the ways in which the different stakeholders of deltaic environments frame the vulnerability of residents of deltas to climate change. The Volta River Delta (VRD) of Ghana is a compelling site in which to conduct such an examination because of the clear climaterelated changes taking place in the Delta, and the fact that like many …


The Economic Impacts Of Forest Timber Methods In Washington State: A Hedonic Approach, Kaleb Javier Jan 2017

The Economic Impacts Of Forest Timber Methods In Washington State: A Hedonic Approach, Kaleb Javier

All Master's Theses

Washington State is one of the nation’s leaders in timber production. This paper establishes literature gap regarding the economic impacts of forest timber management methods. In this research, I employ a data set of 170,141 home sales across eleven counties of western Washington to estimate the impact that even-age and uneven-age forest cutting methods have on the local real-estate market. I estimate two sets of hedonic fixed effect regression models to control for omitted variable bias and spatial autocorrelation. The results show statistically significant impacts on property values for both cutting methods, adding important information for forest managers.

Ideas And Perspectives: How Coupled Is The Vegetation To The Boundary Layer?, Martin G. De Kauwe, Belinda E. Medlyn, Jürgen Knauer, Christopher A. Williams

Geography

Understanding the sensitivity of transpiration to stomatal conductance is critical to simulating the water cycle. This sensitivity is a function of the degree of coupling between the vegetation and the atmosphere and is commonly expressed by the decoupling factor. The degree of coupling assumed by models varies considerably and has previously been shown to be a major cause of model disagreement when simulating changes in transpiration in response to elevated CO2. The degree of coupling also offers us insight into how different vegetation types control transpiration fluxes, which is fundamental to our understanding of land-atmosphere interactions. To explore this issue, …

Urban Non-Timber Forest Products Stewardship Practices Among Foragers In Seattle, Washington (Usa), Rebecca J. Mclain, Melissa R. Poe, Lauren S. Urgenson, Dale Blahna, Lita P. Buttolph

Geography Faculty Publications and Presentations

Our research seeks to expand the concept of urban environmental stewardship to include the everyday stewardship practices of urban nontimber forest products foragers. Ethnographic data from 58 urban foragers and 18 land stewards in the city of Seattle (USA) revealed that foragers reported using a variety of practices to enhance and minimize negative desirable species and their habitats. Many of these practices were identical to those practiced by restoration volunteers in formal programs and align with Seattle Parks Department management objectives. Foragers actively sought to learn more about what practices are sustainable; many mentored others in sustainable harvesting practices. Most …

Accurate simulation of extreme precipitation events remains a challenge in climate models. This study utilizes hourly precipitation data from ground stations and satellite instruments to evaluate rainfall characteristics simulated by the NASA-Unified Weather Research and Forecasting (NU-WRF) regional climate model at horizontal resolutions of 4, 12, and 24 km over the Great Plains of the United States. We also examined the sensitivity of the simulated precipitation to different spectral nudging approaches and the cumulus parameterizations. The rainfall characteristics in the observations and simulations were defined as an hourly diurnal cycle of precipitation and a joint probability distribution function (JPDF) between …


No-Place, New Places: Death And Its Rituals In Urban Asia, Lily Kong Jan 2017

No-Place, New Places: Death And Its Rituals In Urban Asia, Lily Kong

Research Collection School of Social Sciences

In many Asian cities, particularly those that confront increasing land scarcity, the conversion from burial to cremation has been encouraged by state agencies in the last several decades. From Hong Kong to Seoul to Singapore, planning agencies have sought to reduce the use of space for the dead, in order to release land for the use of the living. More secular guiding principles regarding efficient land use in these cities had originally come up against the symbolic values invested in burial spaces, resulting in conflicts between different value systems. In more recent years, however, the shift to cremation and columbaria …


Monitoring Pollen Counts And Pollen Allergy Index Using Satellite Observations In East Coast Of The United States, Murat Cagatay Kececi Jan 2017

Monitoring Pollen Counts And Pollen Allergy Index Using Satellite Observations In East Coast Of The United States, Murat Cagatay Kececi

Electronic Theses and Dissertations

Allergic diseases have become increasingly common over the world during the last four decades, and they are affecting millions of people. Pollination is an important process in the life cycle of plants. However, pollen exposure is associated with allergic diseases such as asthma and seasonal allergic rhinitis (hay fever). As a result, the total annual expenditure for asthma-associated morbidity is about $56 billion in the United States, and the overall cost of allergic diseases is over $18 billion annually. For allergic rhinitis, the annual medical cost is approximately $3.4 billion. The intensity and frequency of the pollen exposures can be …


A Comparison Of Land Use And Land Cover In Public Lands Of The Northwestern Great Plains And High Plains Ecoregions And The Implications For Grassland Birds, Dawn L. Siemonsma Jan 2017

A Comparison Of Land Use And Land Cover In Public Lands Of The Northwestern Great Plains And High Plains Ecoregions And The Implications For Grassland Birds, Dawn L. Siemonsma

Electronic Theses and Dissertations

Loss and degradation of grassland habitat are driving forces that contribute to widespread declines of grassland birds in the United States. Many studies have evaluated habitat needs for the conservation of grassland birds, but the relative contribution of public lands in representing and maintaining avian biodiversity remains poorly understood. Having a better understanding of the role that publicly managed grasslands play in the conservation of grassland bird habitat is important for assessing the value of the investment the American public makes in these lands. Therefore, I investigated spatial relations among variations in amounts and distributions of publicly owned and managed …

The Economic Impacts Of Cougars In Western Washington, Todd Stoothoff Jan 2017

The Economic Impacts Of Cougars In Western Washington, Todd Stoothoff

All Master's Theses

The combination of increasing cougar populations and the rising human population in Wildland-Urban Interface (WUI) areas suggests that the number of human-cougar encounters will rise as well. The increase in human-cougar encounters creates potential issues in regard to public safety, public policy, and management of predators. For the purposes of this research, I employ a housing dataset for eleven counties in western Washington in order to quantify the impacts of a confirmed cougar sighting on the sale value of a home. Specifically, I employ the hedonic real estate price model. Results show statistically significant impacts on housing values in the …


Critical Agrarian Studies In Theory And Practice, Marc Edelman, Wendy Wolford Jan 2017

Critical Agrarian Studies In Theory And Practice, Marc Edelman, Wendy Wolford

Publications and Research

Abstract: In this introductory article we argue for renewed attention to life and labor on and of the land—or what we call the field of Critical Agrarian Studies. Empirically rich and theoretically rigorous studies of humanity’s relationship to “soil” remain essential not just for historical analysis but for understanding urgent contemporary crises, including widespread food insecurity, climate change, the proliferation of environmental refugees, growing corporate power and threats to biodiversity. The article introduces an innovative and varied collection of works in Critical Agrarian Studies and also examines the intellectual and political history of this broader field.

Climate Change Adaptation For Southern California Groundwater Managers: A Case Study Of The Six Basins Aquifer, Frank Lyles Jan 2017

Climate Change Adaptation For Southern California Groundwater Managers: A Case Study Of The Six Basins Aquifer, Frank Lyles

Pomona Senior Theses

Groundwater has been very important to the economic development of Southern California, and will continue to be a crucial resource in the 21st century. However, Climate Change threatens to disrupt many of the physical and economic processes that control the flow of water in and out of aquifers. One groundwater manager, the Six Basins Watermaster in eastern Los Angeles and western San Bernardino Counties, has developed a long-term planning document called the Strategic Plan that mostly fails to address the implications of Climate Change, especially for local water supplies. This thesis presents an in-depth analysis of the Six Basin Watermaster’s …

Pomona Senior Theses

Given my experiences as a young conservation advocate, I saw a need to teach students the importance of interconnectedness, cultural awareness and systems-thinking skills through a spatial lens. I believe these skills are required for holistic, equitable and sustainable conservation decision-making in local and international contexts. This thesis uses geospatial tools to teach conservation ecology vocabulary and concepts from high school environmental science curriculum in two online resources. The purpose of my lesson plan is to show students how conservationists address complex conservation and land-use challenges using the Jane Goodall Institute’s community-centered conservation approach as a case-study. My hope is …


Remote Sensing Of World War Ii Era Unexploded Bombs Using Object-Based Image Analysis And Multi-Temporal Datasets: A Case Study Of The Fort Myers Bombing And Gunnery Range, Bryan Byholm Jan 2017

Remote Sensing Of World War Ii Era Unexploded Bombs Using Object-Based Image Analysis And Multi-Temporal Datasets: A Case Study Of The Fort Myers Bombing And Gunnery Range, Bryan Byholm

All Graduate Theses, Dissertations, and Other Capstone Projects

During World War II, United States Army and Navy pilots trained on several hundred bombing ranges encompassing more than 12 million acres of land, leaving behind crater-scarred landscapes across the country. Post-war estimates suggest that 10-15% of aerial bombs used failed to detonate as intended, so these areas today are contaminated by a large number of dangerous unexploded bombs (UXB) which remain under the surface. Until recently, detecting UXB has been a tedious and expensive process done in three stages: (1) identifying and mapping general areas of concentrated bomb craters using historical air photos and records; (2) intensely searching these …


Evaluating The Potential Of A Geospatial/Geostatistical Methodology For Locating Rain-Derived Infiltration And Inflow Into Wastewater Treatment Systems In The Minneapolis/St. Paul Metropolitan Area, Minnesota, Usa, Vinson Aaron Williams Jan 2017

Evaluating The Potential Of A Geospatial/Geostatistical Methodology For Locating Rain-Derived Infiltration And Inflow Into Wastewater Treatment Systems In The Minneapolis/St. Paul Metropolitan Area, Minnesota, Usa, Vinson Aaron Williams

All Graduate Theses, Dissertations, and Other Capstone Projects

A significant issue facing municipal wastewater treatment infrastructure (WWTI) is how to manage infiltration and inflow (I/I). I/I of rain and ground water permeate into WWTI after precipitation events, periods of groundwater table rise, and percolation from surrounding surface waters. This can create discharges above the infrastructure's flow capacity, increase costs for processing the wastewater and add undesired stress to aging wastewater networks. In an attempt to assess this problem cost and time inefficient approaches have commonly been applied. This study utilizes a new and more radical methodology to try and make WWTI management more efficient. This study applies ArcGIS …


Information Technology Approaches To Forest Management, Mary Snow, Richard Snow Jan 2017

Information Technology Approaches To Forest Management, Mary Snow, Richard Snow

Publications

The majority of the world’s forests occur where there is a dry season long enough to affect a seasonal change in the forest community. The seasonal forest may include evergreen, semi-deciduous, deciduous trees, or some combination of these. Local differences in soil or other site characteristics often determine which community persists. Since the seasonal forests exist where there is seasonal precipitation, the character of the forest is closely associated with the length of the rainy season. As the length of the rainy season decreases, the density of the canopy decreases. If the global climate system warms and prolonged drought gives …


Cocoa And Carbon: Remedying Forest Governance Through Community Participation In A Redd+Pilot In Ghana, Manali Baruah Jan 2017

Cocoa And Carbon: Remedying Forest Governance Through Community Participation In A Redd+Pilot In Ghana, Manali Baruah

Theses and Dissertations

Global loss and degradation of forests are well documented, and the potential role of forests in climate change mitigation is widely recognized. While forests are key to human well-being, forest resource management in the developing world is fraught with governance challenges. Despite policy discourses that emphasize the importance of local participation in the management of forest resources, it is rarely practiced. Many national governments and non-governmental organizations have set up efforts around the collaborative management of forest resources with local communities to tackle forest loss. However, the operationalization of participatory principles and the effectiveness of these collaborative initiatives are not …


Contesting The Generic Refugee: Siv Identity, Community, And Agency During Resettlement, Benjamin J. Sylvester Jan 2017

Contesting The Generic Refugee: Siv Identity, Community, And Agency During Resettlement, Benjamin J. Sylvester

Theses and Dissertations

This thesis examines the complexity of identity and community formation by Special Immigrant Visa (SIV) holders during resettlement in Columbia, South Carolina. It explores the ways in which identities coalesce around various themes, such as religion, gender, and military service, how these identities serve to create, expand, and claim membership in communities, and how SIVs exercise agency throughout these processes. Through semi-structured interviews with 9 SIVs in Columbia, SC, this qualitative study highlights the unique, highly individualized ways in which a select group of refugees experience resettlement, how they negotiate their placement within socio-economic hierarchies, and exercise agency to obtain …


Spatial Optimization Methods And System For Redistricting Problems, Hai Jin Jan 2017

Spatial Optimization Methods And System For Redistricting Problems, Hai Jin

Theses and Dissertations

Redistricting is the process of dividing space into districts or zones while optimizing a set of spatial criteria under certain constraints. Example applications of redistricting include political redistricting, school redistricting, business service planning, and city management, among many others. Redistricting is a mission-critical component in operating governments and businesses alike. In research fields, redistricting (or region building) are also widely used, such as climate zoning, traffic zone analysis, and complex network analysis. However, as a combinatorial optimization problem, redistricting optimization remains one of the most difficult research challenges. There are currently few automated redistricting methods that have the optimization capability …


An 'Answer To Hopes And Dreams': Utopianism, Progressivism, And The American Spatial Tradition In The New Deal Resettlement Community Of Greenhills, Ohio, Jared M. Berg Jan 2017

An 'Answer To Hopes And Dreams': Utopianism, Progressivism, And The American Spatial Tradition In The New Deal Resettlement Community Of Greenhills, Ohio, Jared M. Berg

Senior Independent Study Theses

The purpose of this project is to explain what historical forces led to the construction of Greenhills, Ohio. The goal is to show that Greenhills is one example in a very long line of planned residential communities in American history which have been designed in order to solve contemporary societal issues. This has been done by examining how Americans have constructed space in preceding planned communities. Upon examining these examples, it is clear that Greenhills is very much part of what I identify as an American spatial tradition, a community which especially borrows from the utopian and progressive elements of …

Open / Close: Assimilating Immersive Spaces In Visual Communication, Anika Sarin Jan 2017

Open / Close: Assimilating Immersive Spaces In Visual Communication, Anika Sarin

Theses and Dissertations

I am interested in two spaces obverse to each other: open and closed. An open space develops organically based on how people inhabit it. Interacting with an open space is a dynamic, sporadic, multisensory, immersive, and subjective experience. In such spaces, we are confronted with an alternative aesthetic, one that is in conflict with the seamlessness of a closed space. A closed space is anchored on definite variables like structure, use and boundaries. While interaction between people and space is important, the space is tightly controlled and interaction is designed. Through this thesis project, I present a method that metaphorically …


Listening To The Mattole: Lessons In Bioregionalism, Cannabis, And Capitalism From A Northern California Community, Nicola R. Walters Jan 2017

Listening To The Mattole: Lessons In Bioregionalism, Cannabis, And Capitalism From A Northern California Community, Nicola R. Walters

Cal Poly Humboldt theses and projects

In the United States, from the 1960s through the 1970s, nearly a million Americans left urban areas to establish themselves in rural environments; this exodus is now known as the back-to-the-land movement. Nestled in the mountains of Northern California, along a capricious river, and surrounded by natural beauty, the Mattole Valley became home to many of these back-to-the-land immigrants. Seasoned in the social and cultural movements of Berkeley and San Francisco during the 1960s, the “new settlers” transformed the social and environmental landscape of southern Humboldt County as they integrated into rural communities. The Mattole Valley offers a unique look …

Around the world, municipalities are facing new challenges, not the least of which is climate change. This is especially true for rural communities that, for a variety of reasons, will be disproportionately affected by the climatic changes and accompanying policies or programs.

This dissertation, written in manuscript-style, integrates climate change and social-ecological scholarship to address the unique character of rural communities, to communicate the complexity of rural identity through the term "rural character"; and to empower rural communities to incorporate adaptation strategies into their daily municipal operations and planning.

Specifically, this dissertation seeks to answer the following questions: What is …


Utilization Of Landsat Imagery To Assess The Impacts Of Oil And Gas Extraction On The Tazovsky Peninsula, Siberia, Nicholas B. Kline Jan 2017

Utilization Of Landsat Imagery To Assess The Impacts Of Oil And Gas Extraction On The Tazovsky Peninsula, Siberia, Nicholas B. Kline

Graduate Student Theses, Dissertations, & Professional Papers

Climatic warming of the Arctic is leading to landscape change through cascading biophysical feedbacks; development, such as oil and gas exploration and extraction, can accelerate or worsen these impacts. Due to restricted access to oil and natural gas fields, in situ environmental impact studies are only allowed in some regions. Satellite imagery analysis provides a mean for assessing impacts in areas with limited access. The Yamburg oil and gas field in western Siberia serves as a case study to assess the effects of infrastructure on an Arctic landscape.

This project quantifies the land-cover disturbance that occurred during the development and …
