Pan-Arctic Analysis Of Cultural Ecosystem Services Using Social Media And Automated Content Analysis, Claire A. Runge, Vera Helene Hausner, Remi M. Daigle, Christopher Monz

Environment and Society Faculty Publications

In the Arctic, as in many parts of the world, interactions with the natural world are an important part of people's experience and are often recorded in photographs. Emerging methods for automated content analysis of social media data offers opportunities to discover information on cultural ecosystem services from photographs across large samples of people and countries. We analysed over 800,000 Flickr photographs using Google's Cloud Vision algorithm to identify the components of the natural environment most photographed and to map how and where different people interact with nature across eight Arctic countries. Almost all (91.1%) of users took one or …

“Wilderness” Revisited: Is Canadian Park Management Moving Beyond The “Wilderness” Ethic?, Megan Youdelis, Roberta Nakoochee, Colin O'Neil, Elizabeth Lunstrum, Robin Roth

Global Studies Faculty Publications and Presentations

This paper questions whether the rescaling of conservation practice in Canada to include local and Indigenous communities, NGOs, and private market-based actors represents a move away from wilderness-thinking in conservation, and what implications this might have for the future of conservation in Canada. We explore the links between Cronon's “wilderness” ethic and coloniality, racism/sexism/classism, and political economy, and the extent to which recent trends in conservation practice, such as co-management arrangements, private tourism proposals, and a shift in programming to attract a diverse public to parks, help us to move beyond the limited vision for conservation and environmentalism that the …

Hydrogeochemical Characterization And Speleogenesis Of Sistema Huautla In Oaxaca, Mexico, Fernando Hernandez

Masters Theses & Specialist Projects

Sierra Mazateca, Mexico is home to Sistema Huautla, the deepest cave in the Western hemisphere with 1,560 meters of depth and 90 kilometers of passage, including 26 entrances distributed in a high-relief, karstified terrain, within the Sistema Huautla Karst Groundwater Basin. Exploration of the cave has generated research questions about its evolution and geomorphology given the different vadose and phreatic zones impacted by tectonic and incision processes. Dye traces during this study of Cueva de La Peña Colorada confirmed it is a fossil resurgence of the cave system. An additional cave, Cueva Elysium, was connected hydrologically in 2019, expanding the …

Covid-19 Is Spatial: Ensuring That Mobile Big Data Is Used For Social Good, Age Poom, Olle Järv, Matthew Zook, Tuuli Toivonen

Geography Faculty Publications

The mobility restrictions related to COVID-19 pandemic have resulted in the biggest disruption to individual mobilities in modern times. The crisis is clearly spatial in nature, and examining the geographical aspect is important in understanding the broad implications of the pandemic. The avalanche of mobile Big Data makes it possible to study the spatial effects of the crisis with spatiotemporal detail at the national and global scales. However, the current crisis also highlights serious limitations in the readiness to take the advantage of mobile Big Data for social good, both within and beyond the interests of health sector. We propose …

A Logistic Regression Analysis Of Life Satisfaction Amongst African Immigrants In Hamilton, Canada, Boadi Agyekum

Societies Without Borders

Many minority immigrants currently face severe human rights violation through discrimination and racism, influencing how they rate their life satisfaction in their host destinations. This paper examines the factors that affect African immigrants’ life satisfaction in a mid-sized Canadian city. Using a combination of descriptive and multivariate methods applied on a sample survey (n=236) conducted in Hamilton, Ontario, this article investigates socio-demographic and health-related factors that predict life satisfaction amongst African immigrants, specifically, Ghanaians and Somalis. Findings suggest that Ghanaian immigrants reported greater life satisfaction than their Somali counterparts. People with residency in Canada over 10 years are more likely …

Geospatial Analyses Of Seismic Hazards And Risk Perception In Libya, Somaia Suwihli

Graduate Theses and Dissertations

Libya is not considered a highly active seismic region. However, several earthquakes of magnitude >5.0 have occurred there. This dissertation analyzes the seismicity of Libya in order to better understand earthquake hazards, related geomorphic features, and the current evolution of Libyan perceptions of seismic risk. The first article developed a baseline of past and current seismic inventory in Libya, which represented an assessment of Libya seismic hazard by translating, analyzing, and compiling historical sources and archaeological data. This study shows that Libya has experienced earthquakes in varying degrees since ancient times. Through the spatial and temporal distribution of earthquakes from …

Digital Mapping Of Togo’S Soil Fertility: Savannah Region, Aminou Saibou

International Programs

A soil assessment was carried out in the savannah region of Togo in 2018, aiming at drawing the digital map of Togo’s soil fertility and making fertilizer recommendations. Soil samples were taken from geo-referenced GPS points and were analyzed for parameters such as water pH, Organic matter, available phosphorus and exchangeable potassium. Thematic maps have been drawn using an ArcGIS package. The results showed that the soils of the Savannah region in Togo are mainly (84%) not very acidic (pH = 5.5 to 6.5), overall poor to very poor (84%) in organic matter (<2% OM), essentially poor to very poor (86%) in available phosphorus (<15 mg/kg of soil) and mostly very poor (87%) in exchangeable potassium (<90 mg / kg of soil). These results allowed the agricultural research institute of Togo to make fertilizer use recommendations and to develop, in partnership with Morocco, a digital platform (fertitogo.tg ) for decision making in crop fertilization.

Gentrification & The South Bronx: Demographic And Socioeconomic Transformations In Bronx Community District #1, Lawrence Cappello

Center for Latin American, Caribbean, and Latino Studies

Introduction:

In recent decades skyrocketing real estate values throughout New York City have prompted residents to seek out reasonably priced housing and speculative investment opportunities in traditionally poorer neighborhoods. This is commonly referred to as “gentrification."

This report examines the extent of gentrification in the South Bronx neighborhoods of Melrose, Mott Haven, and Port Morris – officially designated Bronx Community District #1 – widely known as one of New York City’s prominent Latino areas. It presents key socioeconomic and demographic trends between 1990 and 2017. It also looks at topics such as employment, income structures, poverty rates, language acquisition, race/ethnicity, …

Pre-Emptive Detection Of Mature Pine Drought Stress Using Multispectral Aerial Imagery, Nancy Grulke, Jason Maxfield, Phillip Riggan, Charlie Schrader-Patton

Biology Faculty Publications and Presentations

Drought, ozone (O₃), and nitrogen deposition (N) alter foliar pigments and tree crown structure that may be remotely detectable. Remote sensing tools are needed that pre-emptively identify trees susceptible to environmental stresses could inform forest managers in advance of tree mortality risk. Jeffrey pine, a component of the economically important and widespread western yellow pine in North America was investigated in the southern Sierra Nevada. Transpiration of mature trees differed by 20% between microsites with adequate (mesic (M)) vs. limited (xeric (X)) water availability as described in a previous study. In this study, in-the-crown morphological traits (needle chlorosis, …

Immigrants And Crime, Daniel L. Stageman

Publications and Research

The gap between public perception of immigrant criminality and the research consensus on immigrants’ actual rates of criminal participation is persistent and cross-cultural. While the available evidence shows that immigrants worldwide tend to participate in criminal activity at rates slightly lower than the native-born, media and political discourse portraying immigrants as uniquely crime-prone remains a pervasive global phenomenon. This apparent disconnect is rooted in the dynamics of othering, or the tendency to dehumanize and criminalize identifiable out-groups. Given that most migration decisions are motivated by economic factors, othering is commonly used to justify subjecting immigrants to exploitative labor practices, with …

Using Soil Geospatial Properties And Environments To Explore Microbial Diversity, Sharon Faye Smith

Graduate Theses and Dissertations

Soil microorganisms help maintain nutrient cycling, control carbon sequestration, impact plant productivity, and influence several soil chemical and physical properties; yet, the processes that control the microbial composition of soil and how environmental changes may affect the composition and activity of these organisms at different scales remains a difficult and intriguing puzzle for soil scientists, ecologists, and modelers. Wetlands are endangered and important ecosystems that provide several services, which are directly linked to soil function. However, few wetland assessments consider the soil environment and microbial ecology. Linking soil microbial community composition and distribution patterns to soil physio-chemical properties would provide …

Cuban Migrants And The Making Of Havana's Property Market, Gertjan Wijburg, Manuel B. Aalbers, Federica Bono

Political Science & Geography Faculty Publications

The emerging literature on the globalization of real estate has addressed how internationally circulating capital has increasingly found its ways into housing markets of the "Global South". With relatively underdeveloped financial and real estate markets, these countries have discursively and materially been rebranded as emerging markets, that is, they have been shaped into frontiers in the global urbanization of capital. In this paper we scrutinize the transnational real estate networks that shape and reshape the Cuban housing market. First, we reconstruct how, following the 2011 legalization of housing prices set between buyers and sellers, Cuban migrants and a few foreign …

Immigrant Belonging In Belgium: Laws, Localities, And Living Together, Samuel P. Nielson

Theses and Dissertations

Nationalism is rising in Europe and the world. Much of it responds to massive migration, with nationalistic Europeans vocalizing their belief that immigrants do not “belong” in their countries. Many states respond to this influx of people and rising antiimmigrant sentiment by creating laws demanding immigrant “integration.” Yet a clear understanding of what defines “integration” remains elusive. So too does an understanding of how laws aimed at immigrant integration influence relationships between immigrants and local citizens, institutions, and spaces. This research addresses both of these points in Belgium, a politically and culturally fractured country that serves as a microcosm of …

Spatio-Temporal Modeling Of Earthquake Recovery, Sahar Derakhshan

Theses and Dissertations

The recovery process after a major disaster or disruption, is impacted by the inequality of risk prior to and post event. In the past decades there has been few efforts to model the recovery process and the focus is mainly on staged models (i.e. emergency, restoration, and reconstruction). The overarching research question asks how a non-stage-like model could apply to the recovery process. This study poses three broad questions: 1) what are the indicators suitable for monitoring the recovery process; 2) what are the driving factors of differential recovery trends; and 3) what are the predicted development trajectories for communities …

Graduate Theses and Dissertations

East Africa encompasses numerous developing countries and involves one of the most active continental rifts on Earth; namely, the East African Rift System. This region is prone to diverse geohazards due to its geographical location at the plate boundary. Several damaging events had happened across the region and more are predicted to occur in the near future. Therefore, it is crucial to investigate, assess, and forecast natural hazards and potential risks in the region. In this dissertation, remote sensing and Geographic Information System (GIS) were employed to conduct three independent studies focused on assessing geohazards in east Africa. Each study …

Far-Right Extremism In America: A Geospatial Analysis Of Incident Distribution, Meredith Leann Lerma

Graduate Theses and Dissertations

There has been little empirical research on the spatial relationship of violent far-right extremism. Previous studies have only focused on portions of far-right violent incidents, such as homicides, or amalgamated all far-right extremist activity, including legal incidents. This study uses data from the Extremist Crime Database (ECDB) and Southern Poverty Law Center (SPLC) in a temporal frame of 2000 to 2018 to test the relationship of violent incidents against geographic and social factors. The goal is to explore the relationships between macro-level factors and violent far-right extremist incident. The research determines that the presence of hate groups, higher immigrant populations, …

Earth Observation And Sustainable Development Goals, Ramesh P. Singh

Biology, Chemistry, and Environmental Sciences Faculty Articles and Research

"Planet Earth is a dynamic body, which is home to 7.8 billion people, and strong interactions exist between the human population and the Earth’s different components (land, ocean, biosphere, cryosphere and atmosphere). The impacts of such interactions are observed from the day-to-day changes in weather, solar radiation, cloudy conditions, poor visibility, rainfall and frequency of natural hazards around the globe. The dynamic nature of the Earth is evident at the ocean coast through the ocean waves, the nature of these waves varies from day-to-day and also morning to evening. For example, the heights of waves can now be predicted through …

Brazilian Maize Yields Negatively Affected By Climate After Land Clearing, Stephanie A. Spera, Jonathan M. Winter, Trevor F. Partridge

Geography and the Environment Faculty Publications

To date, over 50% of the Brazilian Cerrado has been cleared predominantly for 11 agropastoral purposes. Here, we use the Weather Research and Forecasting model to run 15- 12 year climate simulations across Brazil with six land-cover scenarios: 1) before extensive land 13 clearing; 2) observed in 2016; 3) Cerrado replaced with single-cropped (soy) agriculture; 4) 14 Cerrado replaced with double-cropped (soy-maize) agriculture; 5) eastern Amazon replaced 15 with single-cropped agriculture; and 6) eastern Amazon replaced with double-cropped 16 agriculture. All land-clearing scenarios (2-6) contain significantly more growing season days 17 with temperatures that exceed critical temperature thresholds for maize. …

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. …

Miller, Wenzhao Li, Hesham El-Askary, Ace Vincent B. Flandez, Joshua J. Dagoy, Joselito Francis A. Alcaria, Abdullajid U. Basali, Khaled A. Al-Abdulkader, Ronald A. Loughland, Mohamed A. Qurban

Mathematics, Physics, and Computer Science Faculty Articles and Research

Vegetation is an important ecological component of offshore islands in the Arabian Gulf (AG), which maintains long-term resilience of these islands. This is achieved by influencing sediment retention and moisture acquisition via condensation during periods of high humidity and by providing a variety of microhabitats for island fauna. The resilience of offshore islands’ ecosystems in the Saudi waters is important because they host the largest number of nesting hawksbill and green turtles in the AG. This study defines the characteristics and the long-term trends in vegetation cover of the offshore islands used by sea turtles as nesting grounds in the …

A Multivariate Assessment Of Climate Change Projections Over South America Using Cmip5, Valerie Maria Thaler

Dissertations and Theses

A multivariate assessment of climate model projections over South America from the CMIP5 archive is presented. Change in near-surface temperature, precipitation, evapotranspiration, integrated water vapor transport (IVT), sea level pressure, and wind at multiple pressure levels is quantified across the multi-model suite and an assessment of model-to-model agreement on projected change performed. All models project warming by the mid- and late-21st century throughout the continent, with the highest magnitude projected over tropical regions. The CMIP5 models are in strong agreement that precipitation will decrease in all seasons over portions of Patagonia, especially along the northern portions of the current-climate mid-latitude …
