(Re)Localizing Finland’S Foodshed: Grassroots Movements In Food Distribution And Urban Agriculture, Sophia E. Albov

Graduate Student Theses, Dissertations, & Professional Papers

Finland’s agricultural landscape and food production systems have deep societal roots and intimate connections to the Finnish cultural identity. The thesis explores this cultural heritage through an examination of grassroots food distribution networks rapidly diffusing across Finland and an examination of urban agricultural practices in the capital city of Helsinki. This thesis aims to address the following questions: (1) What is the role of grassroots food distribution networks in Finland, and to what extent are they creating alternative farmer-consumer linkages that support eating local? (2) How is urban agriculture structured and organized in Helsinki and within the broader context of …

Geography and Environmental Studies Faculty Publications

This report details the results of an empirical study that examined perceived health and well-being motives and benefits among visitors to a sample of Alberta’s parks and protected areas. The study revealed several major findings with important policy and management implications. First, the human health and well-being benefits that the visitors expected to receive from visits were perceived to be a major personal motivation in the choice to visit Alberta protected areas. The most important motivation factors identified by respondents were psychological and emotional well-being (89.1% of visitors ranked this important), social well-being (88.3%), physical well-being (80.3%), and environmental well-being …

Impacts Of Urban Areas On Vegetation Development Along Rural-Urban Gradients In The Upper Midwest: 2003-2012, Cole Krehbiel

Electronic Theses and Dissertations

Between one-third and one-half of Earth’s land surface has been directly altered by humans, with the remainder comprised of “human-dominated ecosystems” (Vitousek et al. 2008). Earth’s population has surpassed seven billion, projected to increase by 2.5 billion by 2050 in urban areas alone (United Nations 2014). The rapid urbanization of our planet drives global environmental changes in hydrosystems, biodiversity, biogeochemical cycles, land use and land cover, and climate (Grimm et al. 2008). Urban areas alter local atmospheric conditions by modifying surface albedo and consequently evapotranspiration, releasing energy through anthropogenic heat sources, and increasing atmospheric aerosols, leading to increased temperatures in …

The Biogeography And Diversity Of Termites In Southern Africa, Brianna Lind

Electronic Theses and Dissertations

Termites (Blattodea: Termitoidae) are socially complex insects that are morphologically diverse and live in colonies. They represent a highly specialized form of cockroach that organizes into castes (distinct social groups including workers, soldiers, queen, etc.) that have specific roles within the colony (Eggleton 2010). Globally more than 2,600 species of termites have been described in over 280 genera and, while termites can occur in most climatic zones warmer than tundra, their greatest abundance and ecological significance is in the tropics (Kambhampti and Eggleton 2000). Termites impact many processes, including nutrient cycling, water dynamics, and soil porosity; in African savannas it …

Snow Cover Variability In A Forest Ecotone Of The Oregon Cascades Via Modis Terra Products, Tihomir Sabinov Kostadinov, Todd R. Lookingbill

Geography and the Environment Faculty Publications

Snowcover pattern and persistence have important implications for planetary energy balance, climate sensitivity to forcings, and vegetation structure, function, and composition. Variability in snow cover within mountainous regions of the Pacific Northwest, USA is attributable to a combination of anthropogenic climate change and climate oscillations. However, snowcovered areas can be heterogeneous and patchy, requiring more detailed mapping of snow trends to understand their potential influences on montane forests. We used standard dailyMODIS snow products (MOD10A1.5) to investigate the 15-year record (2000–2014) of snow cover in the predominant forest ecotone of the Oregon Western Cascades. We modeled the ecotone using field …

Whose Urban Forest? The Political Ecology Of Foraging Urban Nontimber Forest Products, Patrick T. Hurley, Marla R. Emery, Rebecca J. Mclain, Melissa R. Poe, Brain Grabbatin, Cari L. Goetcheus

Institute for Sustainable Solutions Publications and Presentations

Drawing on case studies of foraging in Philadelphia, Pennsylvania and Mt. Pleasant, South Carolina, we point to foraging landscapes and practices within diverse urban forest spaces. We examine these spaces in relation to U.S. conservation and development processes and the effects of management and governance on species valued by foragers. These case studies reveal the everyday landscapes of urban foraging and suggest that ideas about what constitutes the suite of appropriate human-environment interactions in the sustainable city are contested and accommodated in diverse ways.

Overcoming Uncertainty And Barriers To Adoption Of Blue-Green Infrastructure For Urban Flood Risk Management, Colin R. Thorne, E. C. Lawson, Connie P. Ozawa, Samantha Hamlin, Leonard A. Smith

Urban Studies and Planning Faculty Publications and Presentations

Blue-Green Infrastructure (BGI) and Sustainable Drainage Systems (SuDS) are increasingly recognised as vital components of urban flood risk management. However, uncertainty regarding their hydrologic performance and lack of confidence concerning their public acceptability create concerns and challenges that limit their widespread adoption. This paper investigates barriers to implementation of BGI in Portland, Oregon, using the Relevant Dominant Uncertainty (RDU) approach. Two types of RDU are identified: scientific RDUs related to physical processes that affect infrastructure performance and service provision, and socio-political RDUs that reflect a lack of confidence in socio-political structures and public preferences for BGI. We find that socio-political …

Monitoring Soil Response To Decreasing Acidic Deposition In A Western Adirondack Tributary Over A 16 Year Period, Michael Robert Antidormi

Legacy Theses & Dissertations (2009 - 2024)

Abstract

Using Storm-Watersheds And A Multi-Criteria Decision Model For Biodiversity Conservation In An Urban Environment, Christina M. Chiappetta

Legacy Theses & Dissertations (2009 - 2024)

Many planning and land use decisions in New York State are controlled at the local (town or municipal) level, not an optimal scale for planning and implementing resource conservation management. Watershed boundaries provide a more ecologically meaningful scale for conservation, because they capture a full range of natural ecosystem processes that span political boundaries. However, defining an urban watershed is complicated by stormwater infrastructure, so standard topographic watershed boundaries may be inadequate for urban resource conservation even when applied at the watershed scale. Storm-watersheds distort both municipal and watershed boundaries, because the flows are redirected in ways that are often …

What We Can Learn From Small Units Of Analysis, Andrew Palmer Wheeler

Legacy Theses & Dissertations (2009 - 2024)

The dissertation is aimed at advancing knowledge of the correlates of crime at small geographic units of analysis. I begin by detailing what motivates examining crime at small places, and show how aggregation creates confounds that limit causal inference. Local and spatial effects are confounded when using aggregate units, so when the researcher wishes to distinguish between these two types of effects it should guide what unit of analysis is chosen. To illustrate these differences, I generate simulations of what happens to effect estimates when you aggregate a micro level spatial effects model or presume a neighborhood effects model.

Discourses Of Disaster, Recovery, And Recovery Actors In Post-Earthquake Haiti : A Critical Discourse Analysis, Juliana Svistova

Abstract

Carnival, Protest, And Community Identity: West Louisville And The Kentucky Derby Festival, Benjamin L. Blandford

Theses and Dissertations--Geography

This dissertation uses “Derby Cruising” in order to open up the tension between African Americans in Louisville and the Kentucky Derby Festival, especially as that tension was manifest in the spaces of West Louisville. The Kentucky Derby Festival has long served as a site of mediation between people of color and official Louisville. Derby Cruising (1998-2005) and protests around the open housing movement (1967) and anti-police violence (2000) are presented as three critical sites where African American expressions of identity, representation, and belonging have been negotiated through the Kentucky Derby Festival at particular historical moments and in particular places in …

Environmental Governance In The Carbon Economy: Regulating Greenhouse Gas Emissions In California's Cap-And-Trade Program, Patrick M. Bigger

Theses and Dissertations--Geography

Since 2006 California has been pursuing the most ambitious climate change policy in the United States, implementing a suite of greenhouse gas reduction measures ranging from automobile refrigerant disposal rules to clean energy standards for electric power utilities. The most significant of these measures is the creation of a cap‐and‐trade program. Through this program, regulators seek to create a knowable price‐signal to incentivize emissions reductions among polluters. Using a suite of ethnographic methods, this dissertation looks at the people, ideas, and institutions that have been mobilized in the creation of California’s cap‐and‐ trade program.

Substantively, the dissertation engages with three …

Trends And Spatial Variability In Dry Spells Across The South-Central United States, Jill C. Trepanier, Michael J. Roberts, Barry D. Keim

Faculty Publications

Annual average and maximum spells with no precipitation in the southern United States are analyzed. In this study, dry spells are defined as consecutive days with no measurable rainfall. The study area includes 70 weather stations in Texas, Oklahoma, Louisiana, Arkansas, Mississippi, and Tennessee. Interarrival times between daily precipitation records for each station provide the data for this analysis. All 70 stations were analyzed from 1950 to 2013. Six stations that each have data for more than 100 years were analyzed for the period from 1908 to 2013. Approximately 25% of stations in the region show significant negative trends through …

Tree-Sway Frequency And The Turbulent Co-Spectral Gap In A Dense Canopy Environment, Katherine L. Ertell

Theses and Dissertations

Today, knowledge of canopy turbulence comes solely from field observations. However, measurements or field observations that are taken at a specific location within the canopy cannot accurately capture the interaction of the wind and the canopy it crosses. Without this complete picture of the atmosphere, the temporal fluctuations that exist in turbulent flows cannot be understood. From an atmospheric perspective, the complex structure of forests significantly influences turbulence in the atmospheric boundary layers (ABL) by consistently imposing both mechanical and thermal forces. This study explores the temporal and spatial characteristics of tree-sway motions and their aerodynamic interactions with coherent turbulence …

Mobile Home Resident Perspectives On Preparedness, Protective Action, And Evacuation For Tornado Hazards, Kevin D. Ash

Theses and Dissertations

More than 1,000 tornadoes strike the United States each year, and no population segment has been impacted to a greater degree than those who live in mobile homes. Despite being only about 7% of the total population, mobile home residents have comprised 40% to 50% of all tornado deaths over the past fifty years. Inhabitants of mobile homes must therefore act quickly to protect themselves when they are threatened by tornadoes. Warning messages instruct mobile home occupants to move to a sturdier building until the storm passes, but what are the residents’ perspectives on this recommended behavior? It is unknown …

Economic Losses And Extreme Tornado Events, Rachel Reeves

Theses and Dissertations

Research on tornado impacts has previously focused mainly on analyzing the deaths and injuries associated with tornadoes. While economic loss from multiple hazards is a well-researched field, little has been done to assess the economic losses sustained during tornado events. Additionally, the literature regarding the Enhanced Fujita scale’s comparability to the Fujita scale is limited. This research aims to add to the literature by statistically analyzing the two tornado scales, determining the movement of tornadoes over time using a cluster analysis, comparing the location of extreme tornadoes to those which produce extreme loss, and looking at the statistical relationship between …

The Meaning Of Place Recovery On The Mississippi Gulf Coast, Ronald L. Schumann, Iii

Theses and Dissertations

Recovery is a post-disaster period of adjustment when individuals, households, neighborhoods, and communities work to overcome the effects of a disaster and regain functionality. Recovery is a multi-scalar process whose outcomes are manifested in the physical landscape; however, assessments of the meaning, progress, and outcomes of recovery are specific to individuals who view the landscape from an embodied perspective within the local social hierarchy. Common recovery measurement techniques used by emergency managers, planners, local leaders, and hazards scholars approximate recovery with reconstruction of physical infrastructure or repopulation of residences. These longitudinal quantitative proxies may claim to represent the status of …

Institutional Resilience Along The Mississippi Gulf Coast In The Context Of Pre- And Post-Hurricane Katrina, Khai Hoan Nguyen

Theses and Dissertations

Building resilience to disasters helps reduce loss of life and property, allowing communities to recover more quickly from shocks and disruptions. Governing institutions are tasked with tremendous responsibility in terms of mitigating risks and enhancing resilience of local communities through proactive planning and policies. It is important to examine how institutional policies have changed pre- and post-disaster to determine their contribution to community resilience. Metrics and indicators can be used to quantitatively assess, establish baseline, track, and monitor resilience at the community level. Few studies have attempted to measure institutional resilience using a set of indicators and metrics, and even …

Ammonium Concentrations Above A Louisiana Sugarcane Field, Wesley Robert Skeeter

Theses and Dissertations

High concentrations of ammonium (NH4+) aerosols can lead to acidification of soils, forest decline, and eutrophication of water ways (Aneja et al. 2003). NH4+ along with its precursor ammonia (NH3) forms a complicated gas aerosol system that is poorly understood and requires further research. Rotating annular denuder systems actively sampled NH4+ from the northern corner of a sugarcane field at 2.89 m and 5.18 m above the northern corner of a sugarcane field in St. Gabriel, Louisiana over 31 days and 31 nights between May 25th and July 27th of 2011. These data were used to calculate the average NH4+ …

A Tale Of Two Landscapes: Examining Alienation And Non-Visitation Among Local African American Fishers At Congaree National Park, Janae Davis

Theses and Dissertations

The Wilderness Act of 1964 limits acceptable activities in federally designated wilderness areas to those associated with leisure, scenic viewing, education and scientific inquiry. These stipulations, which privileged the interests of the early environmental movement’s elite white leaders and disregarded uses valued by racial/ethnic minorities and working class groups, continue to inform wilderness management in national parks. This legacy of exclusion is evidenced by national park visitation statistics showing overrepresentation1 of whites and underrepresentation of African Americans (Meeker, Woods, & Lucas, 1973; P. A. Taylor, Grandjean, & Gramann, 2011). The purpose of this study is to understand how wilderness management …

Institutional Adaptation And Drought Management In The Carolinas, Kirsten Lackstrom

Theses and Dissertations

Drought is one of the costliest hazards faced by the United States, having caused billions of dollars in damage and affected all regions of the country over the past two decades. There have been many efforts to strengthen society’s technical and managerial capacity to respond to drought, mitigate risks, and adopt proactive planning and management strategies. Advances entail the adoption of drought plans, improvements to data collection and monitoring systems, and development of networks to disseminate information and foster communications. Despite recent progress, response remains reactive and crisis-oriented. Management is often uncoordinated across the multiple sectors and fragmented jurisdictions affected …

Remaking Nature In Montana: Topophilic Considerations Of Wolves And Wolf Trapping, Andrew Myers

Graduate Student Theses, Dissertations, & Professional Papers

In 2011, after nearly forty years of federal protection, the gray wolf was removed from the Endangered Species List in Montana and its management entrusted to the Montana Fish, Wildlife & Parks. The implementation of public trapping seasons in 2012 as a method to control wolf populations has further inflamed an already embroiled debate. The purpose of this research was to investigate how the presence of wolves and wolf trapping impacts human attachments to landscapes of “nature” in Montana by focusing on the following questions: What are the public’s social constructions of wolves? What are the public’s social constructions of …

Analyses Of Potential Ravine And Bluff Stabilization Sites Within The Blue Earth And Le Sueur River Basins, Anna My-Tien T. Tran

All Graduate Theses, Dissertations, and Other Capstone Projects

The United States Environmental Protection Agency (USEPA) has listed much of the Upper Mississippi River (UMR) basin as impaired waters due to excessive turbidity, sedimentation, and nutrient loading. Of particular importance are the associated environmental problems (e.g. eutrophication, habitat and wetland loss, loss of biodiversity, and changes in water quality) that have developed within Lake Pepin, a popular recreational riverine lake of the UMR. Three major drainages contribute to these issues and empty in to the UMR near Lake Pepin - the Minnesota River Basin (MRB), St. Croix River, and UMR. The MRB makes up approximately one-third of the drainage …
