Methodological Advances For Understanding Social Connectivity And Environmental Implications In Multi-Use Landscapes, Matthew Clark 2019 Boise State University

Methodological Advances For Understanding Social Connectivity And Environmental Implications In Multi-Use Landscapes, Matthew Clark

Boise State University Theses and Dissertations

Integrated social-ecological systems research is challenging; complicated feedback and interactions across scales in multi-use landscapes are difficult to decouple. Novel methods and innovative data sources are needed to advance social-ecological systems research. In this thesis, we use network science as a means of explicitly assessing feedback between social and ecological systems, and internet search data to better predict visitation in protected areas. This thesis seeks to provide empirical examples of emerging social-ecological systems science methods as a precedent for resource managers on-the-ground, as well as extending the line of scientific inquiry on the subject

In the first chapter of this ...


Testing Multivariate Alteration Detection For Tropical Deforestation Using Synthetic Aperture Radar (Sar) And Drone Imagery In Mamomi Valley, Panama, Abigail Bohman 2019 University of Redlands

Testing Multivariate Alteration Detection For Tropical Deforestation Using Synthetic Aperture Radar (Sar) And Drone Imagery In Mamomi Valley, Panama, Abigail Bohman

MS GIS Program Major Individual Projects

Monitoring tropical deforestation poses a juxtaposition of urgency and difficulty. Because of nearly constant cloud cover in the tropics, heavily studied and widely implemented methods using multispectral satellite imagery to do large-scale land monitoring are not possible. Being an active sensing system that can penetrate through clouds, Synthetic Aperture Radar (SAR) solves this issue, making it one of the best opportunities for tropical forest change in the tropics. In Mamoní Valley, Panama, Multivariate Alteration Detection (MAD) analysis was used with SAR Ground Range Detected imagery from the European Space Agency’s (ESA) Sentinel 1 satellite to test its viability for ...


Evaluating The Presence Of The Endocrine Disruptor 4-Nonylphenol In California Glaciers, Jonah Lay 2019 University of Redlands

Evaluating The Presence Of The Endocrine Disruptor 4-Nonylphenol In California Glaciers, Jonah Lay

MS GIS Program Major Individual Projects

The use of GIS in addressing environmental problems is evident in its application to the Sierra Nevada mountain range glaciers in California. The presence of 4-nonylphenol (4NP) in pesticides used in agriculture has led to its accumulation in California glaciers through onshore wind deposition. As an endocrine disruptor, 4NP poses a threat to human health because it can interrupt and alter physiological processes such as human development and metabolism, and lead to ovarian and prostate cancer at higher concentrations. To evaluate the mass of 4NP in the glacier, GIS analysis is conducted with considerations of wind direction, topographic features, and ...

Urban (Un)Planning And Social Vulnerability In The Context Of Rapid Urbanization And Data Constraints: A Quantitative Study Of Dar Es Salaam, Tanzania., Sheliza Bhanjee

Electronic Theses and Dissertations

This dissertation explores intersections between vulnerability and urban planning in Sub-Saharan Africa, where distinct forms of urbanization are occurring and where there are significant data constraints limiting local studies and urban assessments in the region. The three studies which make up this dissertation offer methodological and theoretical pathways toward examining and measuring the influence of urbanization and planning factors on vulnerability of urban populations in the region. The first study is a literature review and examines existing literature for vulnerability conceptualization in urban environments, the notion of ‘urban vulnerability’, and roles of urban planning and related factors in relation to ...


Identifying Oak Tree Mortality Using Image Analysis, Zemenu Teshome Ambelu 2019 University of Redlands

Identifying Oak Tree Mortality Using Image Analysis, Zemenu Teshome Ambelu

MS GIS Program Major Individual Projects

Oak trees cover more than 8 million hectares of land in California. They have a significant role in providing an anchor for many wildlife habitats, settling soil for a watershed, and preserving the beauty of nature and the environment. Drought stress, wildfires, sudden outbreak of native pest occurrence, and improper interaction with humans, threaten California oaks. The Wildlands Conservancy’s Wind Wolves Preserve has a great concern for oak tree mortality. But has had difficulty finding and mapping oak tree health. To assess and monitor oaks field data collection has been expensive and timeconsuming, and field data collection may not ...


Drug Trafficking, State Capacity, And The Post-Soviet Condition In The Kyrgyz Republic, Christopher George Cowan 2019 University of Arkansas, Fayetteville

Drug Trafficking, State Capacity, And The Post-Soviet Condition In The Kyrgyz Republic, Christopher George Cowan

Theses and Dissertations

Following the collapse of the Soviet Union, the newly independent states of Central Asia faced numerous challenges. These included cultivating new national identities and state capacity, managing new borders, and addressing issues of conflict and political violence. Converging with these challenges – a booming trade in opium and heroin originating in neighboring Afghanistan. Central Asia quickly became a key route for opiates originating in Afghanistan and transiting to Russia and Europe. The Kyrgyz Republic lies at the southeastern corner of this region, along one of the world’s busiest drug trafficking routes.

This thesis examines state and societal responses to narcotics ...

Lidar-Based Sinkhole Detection And Mapping In Knox County, Tennessee, J Clint Shannon, David Moore, Yingkui Li, Cathy Olsen 2019 University of Tennessee, Knoxville

Lidar-Based Sinkhole Detection And Mapping In Knox County, Tennessee, J Clint Shannon, David Moore, Yingkui Li, Cathy Olsen

Pursuit - The Journal of Undergraduate Research at the University of Tennessee

Sinkholes are one of the major causes of damage to roads, buildings, and other infrastructure throughout the US. Sinkholes near or on roads are especially costly and occasionally deadly. Knox County and much of East Tennessee are located within karst areas (comprised of porous and soluble limestone and dolomite), deeming it at risk for sinkholes. Currently, Knox County uses contour maps to manually identify sinkholes. Supported by a geographic information system (GIS), we developed a streamlined model to identify the locations and extents of potential sinkholes using 1.3-ft resolution LiDAR (Light Detection and Ranging) data and applied it to ...


Visualization Of Uncertain Boundaries Of Undersea Features, Hyowon Ban, Hyo Hyun Sung 2019 California State University, Long Beach

Visualization Of Uncertain Boundaries Of Undersea Features, Hyowon Ban, Hyo Hyun Sung

International Journal of Geospatial and Environmental Research

There have been several studies that detect, measure, analyze, and visualize the undersea features by using technologies in multiple disciplines including geography and oceanography. However, definitions of the undersea features often vary among the existing leading literature. Due to this reason the geographical boundary for a certain undersea feature is sometimes not identical among the definitions. In this study, we explore semantic uncertainty in the definitions of some undersea features and apply approaches from fuzzy-set theory and geographic information science on empirical bathymetric data to visualize the uncertain boundaries of the undersea features. Results from this study demonstrate that the ...


Hemispheric And Continental Scale Patterns Of Similarity In Mountain Tundra, George P Malanson, Risto Virtanen, Andrea J Britton, Borja Jiménez-Alfaro, Hong Qian, Alessandro Petraglia, Marcello Tomaselli, David Cooper, Christian Damm, Richard H Pemble, Robert B Brett 2019 University of Iowa

Hemispheric And Continental Scale Patterns Of Similarity In Mountain Tundra, George P Malanson, Risto Virtanen, Andrea J Britton, Borja Jiménez-Alfaro, Hong Qian, Alessandro Petraglia, Marcello Tomaselli, David Cooper, Christian Damm, Richard H Pemble, Robert B Brett

Department of Geographical and Sustainability Sciences Publications

Understanding the full range of biodiversity patterns from local to global scales, through the study of the drivers of multiscale plant community composition and diversity, is a current goal of biogeography. A synthetic understanding of to what extent vegetation compositional patterns are produced by biotic factors, geography or climate and how these patterns vary across scales is needed. This lack hinders prediction of the effects of climate change in global vegetation. Variation in community composition is examined in relation to climatic difference and geographic distance at hemispheric and continental scales. Vascular plants and bryophytes in 13 mountain regions were analyzed ...


Empirical Analysis Of Urban Sprawl In Canadian Census Metropolitan Areas Using Satellite Imagery, 1986-2016, Xiaoxuan Sun 2019 The University of Western Ontario

Empirical Analysis Of Urban Sprawl In Canadian Census Metropolitan Areas Using Satellite Imagery, 1986-2016, Xiaoxuan Sun

Electronic Thesis and Dissertation Repository

Major Canadian cities have experienced rapid sprawl in the last 30 years. This dissertation presents two studies that empirically examine the causes of urban sprawl, merging census socioeconomics data and satellite imageries of 11 major Census Metropolitan Areas (CMAs). The monocentric city model and the Tiebout model are the main traditional theories explaining urban boundary changes and mobility residential. The first study focuses on the cross-sectional comparison among the 11 CMAs in 2016. In the second study, we zoom into the Toronto CMA and examine the longitudinal changes in its urban coverage at the fringe. We detect land cover/use ...


How Pennsylvanians Define Environmental Justice, Kayla Hofmann 2019 Ursinus College

How Pennsylvanians Define Environmental Justice, Kayla Hofmann

Sociology Summer Fellows

The Pennsylvania Department of Environmental Protection (DEP) defines an environmental justice area as any census tract that partially or wholly includes a 30 percent or greater minority population or 20 percent or more of a population living in poverty. However, little is known about how the average Pennsylvanian defines environmental justice, hindering our ability to determine whether the current definition is adequate. Using transcripts from nine listening sessions on the DEP’s tour of affected counties, I address 3 questions: (1) How do people define environmental justice? (2) What do people think are the most pressing issues in each county ...


Urban Tree Survival And Stewardship In A State-Managed Planting Initiative: A Case Study In Holyoke, Massachusetts, Benjamin S. Breger, Theodore S. Eisenman, Madison E. Kremer, Lara A. Roman, Deborah G. Martin, John Rogan 2019 University of Massachusetts Amherst

Urban Tree Survival And Stewardship In A State-Managed Planting Initiative: A Case Study In Holyoke, Massachusetts, Benjamin S. Breger, Theodore S. Eisenman, Madison E. Kremer, Lara A. Roman, Deborah G. Martin, John Rogan

Theodore S. Eisenman

Stewardship is essential for the survival of trees planted in challenging urban conditions and for reaching canopy
cover goals and anticipated benefits. The governance structure of the stewardship network can dictate stewardship
efficacy and ultimately, tree survival. While many planting initiatives are managed locally, the stewardship
network and survival rates of a state-managed initiative are not commonly addressed in scholarly literature.
The Greening the Gateway Cities Program (GGCP) in Massachusetts is planting thousands of trees in
post-industrial cities around the state. We carried out a mixed-methods case study of 2014 to 2016 tree planting
in Holyoke, a GGCP pilot city ...

Enhancing Ontario’S Rural Infrastructure Preparedness: Inter-Community Service Sharing In A Changing Climate — Interim Report 2: Provincial Survey Results, Brenda Murphy, Bryce Gunson 2019 Wilfrid Laurier University

Enhancing Ontario’S Rural Infrastructure Preparedness: Inter-Community Service Sharing In A Changing Climate — Interim Report 2: Provincial Survey Results, Brenda Murphy, Bryce Gunson

Social and Environmental Justice Faculty Publications

Rural communities draw from their history of doing more with less, strong social networks and an intimate relationship with the natural environment to achieve economic innovation, positive social capacity development and environmental sustainability. These spaces also experience challenges including preparing for the impacts of climate change (CC). Ontario has already felt some of these effects leading to millions of dollars of damage to the province’s infrastructure. Exacerbated by an aging infrastructure built by now outdated assumptions, the vulnerability to CC will likely increase and the built-in coping range may not be adequate to handle future climate extremes.

The purpose ...
