Risk Analysis For Asset Protection In Hoyt Arboretum, Portland, Or, Nathan Kossnar

Masters in GIS Practicum Reports

In order to fulfill Tree Risk Assessment Qualification (TRAQ) certification obligations to the International Society of Arboriculture (ISA), this project delineated areas within Hoyt Arboretum where tree hazards have the potential to fall on important infrastructure and areas of frequent use. The project utilized Metro’s RLIS lidar data to generate a canopy height model which was then applied to a variable window filter (vwf) algorithm to determine individual tree heights and locations throughout the park. Previously defined protection areas were used to determine which surrounding trees have the potential to damage structures or injure park visitors in the chance of …

Community Gis Workshop Design & Delivery: Columbia County Geographic Workshop At Scappoose Public Library, Marty Marquis

Masters in GIS Practicum Reports

Geographic information systems (GIS) provide tools for industry, government, and the public to describe, visualize and organize space both conceptually and materially. Because the technology is complicated and potentially expensive, it is often out of the reach of those communities that might most benefit from its use, even as it’s routinely wielded by business interests, bureaucrats, and representative bodies to identify and legitimize administrative boundaries, potential areas for growth and profit, spatially oriented legislation (restricted areas, zoning), and so forth. Communities whose members know how to use a GIS gain potential advantages in deploying narratives that contest official plans for …

Evaluating Behavioral Intention To Increase Classroom Geotechnology Usage Following Geoinquiry Implementation, Erika S. Klose

Theses, Dissertations and Capstones

As educational practices include foundational and cutting-edge preparation, the value of problem-based instruction employing industry-standard technologies increases. Geospatial technologies (GST), are a group of professional technologies, including GIS (Geographic Information Systems), used by industries to make informed decisions with spatial data. This study investigated educator behavioral intention to use GIS/GST in classroom practice, and the moderating effect, if any, of the GeoInquiry, a curricular resource. The UTAUT framework was employed to evaluate and quantify the factors impacting behavioral intention (performance expectancy, effort expectancy, social influence, and facilitating conditions). These data were examined to identify moderation by GeoInquiry usage. One hundred …

Maintaining Connections During The Pandemic: Rural Arts Festivals And Digital Practices, Enya Moore, Bernadette Quinn

Articles

During the COVID lockdowns of 2020/21, the transmission of live or recorded concerts grew exponentially as festival makers embraced digital technologies to a greater degree. Investigating how this digital pivot interrupted festival-making practices is now important given that online and hybrid modes will potentially be used in conjunction with in-person events in the future. This task has relevance for rural areas where digital infrastructures can be under-developed. Yet, place-based, community-organised festivals can play a significant role in sustaining local communities. In this context, we explore the recent digital programming practices of music festivals in West Cork, Ireland. Methodologically, the study …

Legacy Industry And Redlining In American Cities, Mark D. Bjelland, Jacob Foll

Summer Research

Throughout the 1930s, the HOLC created residential security maps which graded residential areas from best to hazardous. This study investigated the connection between the proximity of industry to HOLC-graded zones on residential security maps in the top 50 most populous metropolitan regions in the United States in 1930, utilizing both geospatial and textual analysis. In ArcGIS Pro, ModelBuilder was used to automate the process of identifying and separating HOLC graded zones, creating buffers around industrial land use polygons, clipping the buffers to the HOLC graded zones, and calculating the area of the HOLC graded zones in proximity to industrial area. …

What About Tornadoes Makes Cars Fly?, Fred Haan, Minji Lee

Summer Research

Tornadoes move and evolve throughout their lifetime, causing several types of forces against objects. Although vehicles are observed to fly in real tornadoes, simulating this experimentally and numerically has been very difficult – the vehicles do not seem to want to fly. We studied the effect of pressure gradient forces. These have typically been ignored in past simulations, so we estimated them to see if they add the missing force to get things to fly. Some researchers have made mathematical models of tornado wind fields, so we used those models to estimate pressure gradient forces. We also used some full-scale …

Considering The Shrinking Physical, Social, And Psychological Spaces Of Rohingya Refugees In Southeast Asia, Kendra L. Duran, Robin Al-Haddad, Saleh Ahmed

Global Studies Faculty Publications and Presentations

Refugees experience shrinking social, economic, political, and physical spaces at astonishing rates. However, these shrinking spaces are challenging to trace simultaneously and are rarely considered in policymaking or analysis. Using the Rohingya case study, this paper implores policy analysis to include these spaces, conceptually categorizing them into physical, social, and psychological spaces. Here we chronologize the plight of Rohingya refugees and identify how their spaces have changed over time. Our findings reveal four primary causal relationships linked to Rohingya refugees' fluctuating spaces, including: (I) Bangladesh's policy framework has kept the Rohingya largely isolated, yet their public-private partnerships have expanded their …

No. 57: Pandemic Precarity And Food Insecurity In Urban Ghana During Covid-19, Elizabeth Opiyo Onyango, Bernard Owusu, Jonathan Crush

Hungry Cities Partnership

The impact of the COVID-19 pandemic on urban households in the Global South has not yet been adequately explored, despite an emerging consensus that impacts of the pandemic were more severe in urban than rural Africa. This paper addresses the knowledge gap by examining the relationship between pandemic precarity and food insecurity in Ghana’s urban areas during the pandemic in 2020. The data comes from the World Bank (WB) and Ghana Statistical Service (GSS) COVID-19 High-Frequency Phone Survey. Using a sub-sample of 1,423 urban households, the paper evaluates household experiences of the pandemic. Our findings show that household demographic characteristics …

Carbon Storage Capacity Of Pcci Soils, Noah Millen, Erin Taylor, David Dornbos

Summer Research

• Global climate change (GCC) is a well-documented problem, with CO2 as the most influential greenhouse gas (GHG) driving GCC.
• Plants transfer CO2 from the air to soil organic carbon (SOC).
• Soil is the largest terrestrial sink of organic carbon (2344 Gt)1.
• Agricultural tillage has dramatically reduced the amount of SOC in soils through mineralization and erosion.
• Storing C in soil could reduce the atmospheric C stock, serving to mitigate GCC2

Comparison Of Water Column Properties Derived From An Autonomous Underwater Vehicle And Satellite Based Sources In Lake Michigan, David Bennion

Master's Theses and Doctoral Dissertations

Autonomous underwater vehicles (AUVs) are an emerging technology increasingly being employed in geoscience and ecosystem research in the Great Lakes, capitalizing on their ability to sample large areas fitted with a variety of sensors. Previous to AUV use, chlorophyll measurements were either collected at discrete locations accessed by boats or derived from satellite remote sensing data. An advantage of AUVs is the ability to detect the presence of subsurface formations such as a deep chlorophyll layer or directly measure features such as the extent of the photic zone, which provides the opportunity to compare these in situ measured features to …

No. 58: Wild Foods, The Nutrition Transition And Urban Food Security In Northern Namibia, Ndeyapo Nickanor, Lawrence Kazembe, Jonathan Crush

Hungry Cities Partnership

Rapid urbanization and food system transformation in Africa have been accompanied by growing food insecurity, reduced dietary diversity and an epidemic of non-communicable disease. While the contribution of wild and indigenous foods (WIF) to the quality of rural household diets has been of longstanding attention, research on their consumption and role amongst urban households is much more recent. This paper focuses on the consumption of WIF in three towns in northern Namibia with close ties to the surrounding rural agricultural areas. Based on data from a household survey of food sourcing and consumption patterns in 2018, the paper shows that …

Food security is a significant concern in urban areas (UAs). With the rapid increase in urbanization, addressing this issue has become increasingly important. Despite interventions to tackle food security issues, the world has achieved varying degrees of success in eradicating hunger, and food security in cities is critical. This study examined the unique challenges and opportunities associated with ensuring food security in urban areas. The study reviewed empirical literature and relevant reports in the last five years (2018-2023). This study identified several challenges in ensuring food security in urban regions, across the world, including rising food prices, limited water and …

Power And Politics: The Case Of Urbanization And River Channel Change, Peter Ashmore

Geography & Environment Presentations

Gradual urbanization of a watershed in Toronto, Canada, over 60+ years resulted in major channel changes. The temporal and spatial extent of channel widening are predictable from new analysis tracking changes in total stream power along the river system as urban land cover extended across the watershed, and also produced very high energy large flood events responsible for major channel change. The analysis is a geomorphically-satisfying, quasi-experimental test of theory of river channel change. But it misses important elements of the full trajectory of change that are not physically predictable. Treating urbanization as a neutral physical variable of changing watershed …

Evaluating River Morphology Change With A Geomorphic Form Variation Approach, Corey Dawson, Peter Ashmore, Robert Corry

Geography & Environment Publications

Geomorphic river design strives for natural resilience by encouraging geomorphic form complexity and morphological processes linked to greater habitat diversity. Increasing availability of high-resolution topographic data and spatial feature mapping methods provide advantages for morphological analysis and river restoration planning. We propose and evaluate an approach to quantifying topographic variability of geomorphic form and pixel-level surface roughness resulting from channel planform geometry differences using spatially continuous variety computation applied to component metrics including flow direction, aspect and planform curvature. We define this as the geomorphic form variation (GFV) approach and found it scalable, repeatable and a multi-stage analytical metric for …
