The Rise And Fall Of Wiñaymarka: Rethinking Cultural And Environmental Interactions In The Southern Basin Of Lake Titicaca, Maria C. Bruno, José M. Capriles, Christine A. Hastorf, Sherilyn C. Fritz, D. Marie Weide, Alejandra I. Domic, Paul A. Baker

Department of Earth and Atmospheric Sciences: Faculty Publications

Investigations of how past human societies managed during times of major climate change can inform our understanding of potential human responses to ongoing environmental change. In this study, we evaluate the impact of environmental variation on human communities over the last four millennia in the southern Lake Titicaca basin of the Andes, known as Lake Wiñaymarka. Refined paleoenvironmental reconstructions from new diatom-based reconstructions of lake level together with archaeological evidence of animal and plant resource use from sites on the Taraco Peninsula, Bolivia, reveal frequent climate and lake-level changes within major cultural phases. We posit that climate fluctuations alone do …

Environmental And Spatial Factors Affecting Surface Water Quality In A Himalayan Watershed, Central Nepal, Janardan Mainali, Heejun Chang

Geography Faculty Publications and Presentations

Various spatial interrelationships among sampling stations are not well explored in the spatial modeling of water quality literature. This research explores the relationship between water quality and various social, demographic, and topographic factors in an urbanizing watershed of Nepal with a comparison of different connectivity matrices to conceptualize spatial interrelationships. We collected electrical conductivity and dissolved oxygen data from surface water bodies using a handheld probe and used the data to establish relationships with land use, topography, and population density-based explanatory variables at both watershed and 100-m buffer scales. The linear regression model was compared with different eigenvector-based spatial filtering …

Pollinator Habitat On The University Of Richmond Campus: Assessing The Success Of Pollinator Meadows In The Gambles Mill Eco-Corridor, Mary Berner

Environmental Studies Senior Seminar Projects

Globally, many insect pollinator populations are declining in response to anthropogenic harms including habitat loss due to land-use change and urbanization, climate change, increasing pesticide use, invasive species introductions, and increased pathogen transmission. In order to protect these insects, and the benefits they provide through pollination, habitat must be protected. Much of the effort to protect insect pollinator habitat is occurring in urban areas, where pollinators may struggle to find the resources they need to survive. The purpose of this study was to assess the success of three pollinator meadows created within the Gambles Mill Eco-Corridor (Eco-Corridor) on the University …

Uniformity In Place-Making: How A Focus On Image And Tradition Can Restrict Personal Expression And Repress Queer Identities, Julia Funk

Environmental Studies Senior Seminar Projects

This study looked at the University of Richmond campus, a campus built in a collegiate gothic style of and comprised of uniform buildings and highly managed landscaping. Specifically, it surveyed queer students at UR to ask about their experiences and feelings being on the UR campus. The survey found that a majority of the 44 surveyed students felt pressure to be or act straight, felt there was a lack of queer visibility on campus, felt most uncomfortable in the settings such as the Business School and Greek Life locations and most comfortable in personal housing. Overall, students liked how the …

Survivorship Of The Reintroduced Kihansi Spray Toads Nectophrynoides Asperginis In A Soft Release Experiment At The Kihansi Gorge, Tanzania, Flora John Magige, Nassoro Mohamed

Journal of Humanities and Social Sciences

The Kihansi Spray Toad (KST) Nectophrynoides asperginis is endemic to the unique wetland habitat surrounding the Kihansi Falls, Tanzania, with which it was associated. The species was declared extinct in the wild in 2009 by the International Union for Conservation of Nature (IUCN), following the loss of its unique habitat due to the diversion of the Kihansi River for hydropower production. This study is an initial attempt to determine the survivorship and possible sources of mortality of newborn and adult KSTs placed in cages in their original habitat in the Upper Spray Wetland (USW) and Lower Spray Wetland (LSW) areas. …

How Globalization, Sustainability, And Human Impacts Are Affecting Two Major Mexican Cities: Mexico City And Guadalajara, Cristina Sedano

Electronic Theses, Projects, and Dissertations

Mexico is one of the richest countries in the world, not in terms of economic stability but in terms of natural resources, culture, and atmosphere. When people think of Mexico, they usually think of the high-tension relationship with the United States, their neighboring country to the North. Although there are many diverse historical and present-day characteristics of Mexico, most associate the county with the high levels of crime due to narco and cartels, the high levels of poverty in regional areas, and to some just a party destination. Unbeknownst to many is the thousands year old culture that is passed …

216— Using Rochester’S Family Public Housing In The “Crescent Of Poverty” As A Catalyst For A Solar Initiative, Christopher Miller

GREAT Day Posters

Both the climate crisis and poverty rates in US cities have increased rapidly, with few solutions. This research examines the relative solar potential in public housing developments in Rochester, NY, specifically in the area of concentrated poverty called the “Crescent of Poverty.” Also examined are societal benefits that an inclusive solar/sustainability movement provides for Rochester. Rochester is a mid-sized, diversely populated city with an overall poverty rate >30% and a childhood poverty rate >50% (Murphy, 2018). These alarming rates have contributed to the creation of the “Crescent of Poverty”, where the majority of family public housing developments are located. Solar …

Automatic Features Extraction From Time Series Of Passive Microwave Images For Snowmelt Detection Using Deep-Learning – A Bidirectional Long-Short Term Memory Autoencoder (Bi-Lstm-Ae) Approach., Bienvenu Sedin Massamba

LSU Master's Theses

The Antarctic surface snowmelt is prone to the polar climate and is common in its coastal regions. With about 90 percent of the planet's glaciers, if all of the Antarctica glaciers melted, sea levels will rise about 58 meters around the planet. The development of an effective automated ice-sheet snowmelt monitoring system is therefore crucial.

Microwave remote sensing instruments, on the one hand, are very sensitive to snowmelt and can see day and night through clouds, allowing us to distinguish melting from dry snow and to better understand when, where, and for how long melting has taken place. On the …

Population Collapse And Retreat To Fire Refugia Of The Tasmanian Endemic Conifer Athrotaxis Selaginoides Following The Transition From Aboriginal To European Fire Management, Andres Holz, Samuel W. Wood, Carly Ward, Thomas T. Veblen, David M.J.S. Bowman

Geography Faculty Publications and Presentations

Untangling the nuanced relationships between landscape, fire disturbance, human agency, and climate is key to understanding rapid population declines of fire‐sensitive plant species. Using multiple lines of evidence across temporal and spatial scales (vegetation survey, stand structure analysis, dendrochronology, and fire history reconstruction), we document landscape‐scale population collapse of the long‐lived, endemic Tasmanian conifer Athrotaxis selaginoides in remote montane catchments in southern Tasmania. We contextualized the findings of this field‐based study with a Tasmanian‐wide geospatial analysis of fire‐killed and unburned populations of the species. Population declines followed European colonization commencing in 1802 ad that disrupted Aboriginal landscape burning. Prior to …

Modelling And Mapping The Intra-Urban Spatial Distribution Of Plasmodium Falciparum Parasite Rate Using Very-High-Resolution Satellite Derived Indicators, Stephanos Georganos, Oscar Brousse, Sebastien Dujardin, Catherine Linard, Daniel Casey, Marco Millones, Benoit Parmentier, Nicole P.M. Van Lipzig, Mattias Demuzere, Sabine Vanhuysse, Nicholus Mboga, Vernica Andreo, Robert W. Snow, Moritz Lennert

Geography Articles

The rapid and often uncontrolled rural–urban migration in Sub-Saharan Africa is transforming urban landscapes expected to provide shelter for more than 50% of Africa’s population by 2030. Consequently, the burden of malaria is increasingly affecting the urban population, while socio-economic inequalities within the urban settings are intensified. Few studies, relying mostly on moderate to high resolution datasets and standard predictive variables such as building and vegetation density, have tackled the topic of modeling intra-urban malaria at the city extent. In this research, we investigate the contribution of very-high-resolution satellite-derived land-use, land-cover and population information for modeling the spatial distribution of …

Transitioning From Emergency Remote Learning To Deep Online Learning Experiences In Geography Education, Richard B. Schultz, Michael N. Demers

Publications & Research

Recent events resulting from the Covid-19 pandemic precipitated a triage-like environment wherein experienced faculty were forced to convert courses rapidly to online venues. This unexpected circumstance forced educators to adopt different learning theories of which they were largely unaware. The results were predominantly unsatisfactory for both learner and educator. This paper provides perspectives to this unfortunate circumstance, describes positive and negative aspects of the experiences, presents best practices for deep online learning, and challenges geography educators to learn how instructional design for online courses can be leveraged. The goal is to provide a forum for online learning in geography education.

Socio-Hydrology: An Interplay Of Design And Self-Organization In A Multilevel World, David J. Yu, Heejun Chang, Taylor T. Davis, Vicken Hillis, Landon T. Marston, Woi Sok Oh, Murugesu Sivapalan, Timothy M. Waring

Geography Faculty Publications and Presentations

The emerging field of socio-hydrology is a special case of social-ecological systems research that focuses on coupled human-water systems, exploring how the hydrologic cycle and human cultural traits coevolve and how such coevolutions lead to phenomena of relevance to water security and sustainability. As such, most problems tackled by socio-hydrology involve some aspects of engineering design, such as large-scale water infrastructure, and self-organization in a broad context, such as cultural change at the population level and the hydrologic shift at the river basin or aquifer level. However, within the field of socio-hydrology, it has been difficult to find general theories …

Refugee Camp Education: Hope, Gaps, And Barriers, Allyson Dykstra

Honors Theses

The urgency to provide humane living conditions such as food, shelter, safety and education grows with the refugee population as temporary stays become more permanent. Refugees are staying longer in emergency arrangements, which appears to affect mental health, ability to hope, and sustainable coping mechanisms for these populations. With dissatisfactory conditions in camps, this paper intends to explore how refugees cope with their environment and in what ways needs are not being met, in order to explain the present condition of refugee health, their coping mechanisms, and how to combat it.

The Effects Of Urban Development And The Incidence Of Flooding And Discharge Changes From 1956-2016: A Case Study From Juan Diaz Township, Republic Of Panama, Virgilio De Jesus Quintero Rodriguez

Graduate Theses and Dissertations

The increase in flood occurrences in the Township of Juan Diaz has affected thousands of families and hundreds of businesses and has negatively impacted the lives of thousands of residents, who expect the worse every time there is a prolonged period of rain. Some of the residents lose their appliances, cars, furniture and houses every year. This study examines the relationship between urban development and flooding. Also, it addresses the influences of topography, green cover, population changes, runoff changes, and social dynamics on this relationship. This study implemented the use of thematic cartography, geographic information systems (GIS), personal interviews and …

The War On Winter: How Americans Put Down Roots On The Northern Plains, 1854-1949, Daniel J. Fischer

Graduate Theses and Dissertations

My dissertation is a study of how the United States was able to expand onto the Northern Great Plains, consisting of the Dakotas, Nebraska, and the eastern parts of Wyoming and Montana, between 1854 and 1949 despite the threat to property, comfort, and survival posed by the region’s harsh winters, which brought intense cold, large snowdrifts, and blinding blizzards. This dissertation argues that five tools – government programs, rapidly changing technology, imagination, strong local communities, and toughness – allowed native-born Americans and European immigrants to survive and become increasingly secure in the region. But it also argues that severe gaps …

Spreadsheets-In-Space: A Quantitative Exploration Of Movement, Currency Creation, And Conflict Within Eve Online, Christopher Alan Pryor

Graduate Theses and Dissertations

EVE Online is a massively-multiplayer online game with complex interactions between players and their unique, virtual environment. These relationships are the ongoing results of a conflict-driven economy, but they vary both in duration and by location.

This study attempts to quantify the direct effects of movement and indirect effects of conflict upon economic activity in the form of currency creation and delineate how successfully these relationships can be quantified by narrower time-spans and areas. Results of the mediation models used in this exploration indicate the changing relationship between movement (Ship Jumps), conflict (Ship Kills), and currency creation (Faction Kills) is …

Do You Believe In Ghost Apartments?, Michael Lewyn

Scholarly Works

According to the popular press, expensive cities are being overrun by "ghost apartments"- condominiums owned by wealthy foreigners, but used as investments rather than being rented out to local residents. This article points out that such apartments are in fact a very small percentage of housing supply, even in some cities that are supposedly overran with such condos. More importantly, the existence of new “ghost apartments” does not justify exclusionary zoning policies. If a city popular with foreign investors discourages construction of new housing, investors are likely to purchase older housing units, outbidding local residents for those units. In this …

Multidimensional Analysis Of Vulnerability: Methodological Advances And A Case Study From Malawi., Park Mcmillan Muhonda

Graduate Theses, Dissertations, and Problem Reports (ETD)

Since 1990s rural households in Malawi, constituting 85% of the population, have experienced deepening livelihood vulnerability, often manifested as persistent food insecurity. Livelihood crises have since been blamed on or attributed directly to weather perturbations/climatic shocks i.e. El-Nino induced climate variability/drought conditions. This study revealed that persistent livelihood crisis in rural Malawi cannot be attributed to or squarely blamed on weather shocks alone, rather it is at the intersection of various livelihoods shocks that rural livelihood vulnerability in Malawi is exacerbated i.e. worsening and deepening.

Thus, rural livelihood vulnerability to climate shocks in Malawi is manifest not in isolation but …

Speculations On The Postnatural: Restoration, Accumulation, And Sacrifice At The Salton Sea, Alida Cantor, Sarah Knuth

Geography Faculty Publications and Presentations

Using a regional political ecology lens, this paper explores emerging geographies and politics of a “postnatural” ecomodernist turn in mainstream environmentalism. We examine the unfolding case of ecological restoration and renewable energy development at Southern California’s Salton Sea. Ambitious proposals to restore the massive, increasingly degraded lake (and finance restoration) by reengineering it as a hub for geothermal energy generation and hightech green industry hinge upon the ambiguity and malleability of restoration in an environment long classified as postnatural. These plans coincide with a broader rush on renewable energy sites in the California desert, and mounting conflicts over water and …

Geochemistry Of Archaeological And Marine Environments In Southwest Maine, Heather L. Bushie

Thinking Matters Symposium Archive

Two archaeological excavations for the University of Southern Maine collected sediment columns from select units for geological and chemical analysis. The Spiller Farms site is a Native American site located in Wells, Maine marking a transition period between the Pleistocene and Holocene epochs, 12,000 BP. The Malaga Island site was a historic mixed-race community at the north end of Casco Bay where sediment columns were obtained in near-shore and subtidal zones. The samples obtained from Malaga Island have been radiocarbon dated to 3800 +/- 30 BP at 23 meters below the low-tide line. X-ray fluorescence (XRF) analysis is being conducted …

Deviance Fluidity On The Urban Landscape: Graffiti And Street Art As Non-Normative Placemaking, Alyson M. Mabie

Masters Theses

Graffiti is recognized as an illegal deviant act. Sociologically, deviance is defined by the audience perceiving the act, rather than inherent in the act itself. In this context, deviance is subjective and fluid. This paper explores the spectrum of graffiti from criminal vandalism to celebrated art form in the context of its placement on the urban landscape. The fluidity of deviance is reflected in the concentration of different types of graffiti in different locations. The spatial distribution of graffiti writing, street art, and the equally illegal guerrilla marketing stickers, which mimic graffiti placement and street art styles, were collected in …

Landscapes: the Journal of the International Centre for Landscape and Language

This piece follows the course of the Mapocho river in Chile from its origins in the Andes through to its discharge into the Pacific Ocean. It has also sought to include a number of Scottish words to create a form of polyglossia and experiment with the texture of the prose.

Becoming Human In The Land: An Introduction To The Special Issue Of Heritage: Landscapes, Drew Hubbell

Landscapes: the Journal of the International Centre for Landscape and Language

This introduction to the special issue of Landscapes theorizes the questions suggested by the theme, "Landscape: Heritage." Weaving personal narrative with literary criticism, cultural studies, human geography, and ecology, the essay examines the way humans become human by developing complex relationships with landscapes over time. As landscapes contain the physical traces of human habitation and development, certain narratives of human inhabitants are written and memorialized in and by those landscapes. The monumentalization of specific heritages leads to contests between human groups who require certain heritages to be memorialized, but not others. Greater awareness of one's humanity requires recovery of polyphonic …

Community-Based Initiatives For Neighborhood And Community Rehabilitation: A Case Study Of The Mission District, San Francisco, California, Francesca Monique Gallardo

Cal Poly Humboldt theses and projects

Through the case study of San Francisco, CA’s Mission District, this research project addresses how community-based affordable housing development is operationalized to rehabilitate communities and neighborhoods experiencing effects of gentrification, mass displacement, and cultural dilution. My goals were to identify how the processes of building a sense of community, trust, and cohesion- rehabilitating and critical to affordable housing development efforts in the Mission District? And, how are nonprofit community development organizations engaging with these processes in collaboration with citizen and community partners? The final objective is to provide evidence-based strategies to assist other at-risk minority communities and neighborhoods in the …

Geomorphic Consequences Of Hydroelectricity And Transportation Development Near Celilo Falls, Lower Mid-Columbia River, Washington, Noah I. Oliver

All Master's Theses

Along the Columbia River, hundreds of miles of transportation infrastructure and over sixty hydroelectric dams have been constructed. This altered a rich cultural landscape with evidence of 10,000 years of continuous occupation. Researchers have attempted to understand the impacts of anthropogenic factors on the Columbia River, focusing on the riverine environment. However, the effect of transportation and hydroelectricity developments to eolian landforms on the floodplains and adjoining slopes have not been studied. Focusing on 2,800 acres near Celilo Falls, this study 1) establishes a baseline condition of eolian landforms from 1805 to 1900; 2) conducts an air photo increment analysis …
