A Participatory Drone Mapping And Critical Physical Geography Of Water Security For Irrigation In Northern Ghana, Dinko Hanaan Dinko

Electronic Theses and Dissertations

Dam discourse frequently incorrectly assumes that their emergence unilinearly translates to an expansion of economic opportunities while not considering how dams become sites for the reproduction of inequality and injustice. This dissertation investigates how the politics of irrigation water access are nested in a complex web of physical materialities of the 'natural' environment and power relations, with lived consequences on differentiated social identities in semiarid Ghana. The research draws on transdisciplinary perspectives from political ecology, embodiment, critical physical geography, and mixed methods, including interviews, focus group discussions, surveys, participatory drone mapping, and laboratory analysis of soil biochemical properties. The study …

Testing The Affect Of Modified Sense Of Place, Conservation Ethic, And Good Farmer Identity Measures On Predicting The Adoption Of Cover Crops In Working Landscapes In Iowa, Elizabeth A. Bennett, Morey Burnham, Jessica D. Ulrich-Schad, J. Gordon Arbuckle, Weston M. Eaton, Sarah P. Church, Francis R. Eanes, Jennifer Eileen Cross, Matthew A. Williamson

Human-Environment Systems Research Center Faculty Publications and Presentations

While sense of place (SOP) has been used in amenity landscapes to understand pro-environmental behavior, in working landscapes, SOP has not been a valid or reliable predictor for explaining conservation behavior. In this paper, we advance theory on SOP in working landscapes by assessing the relationship between several new and modified sense of place measures and farmer adoption of cover crops in Iowa. We used data from a 2018 survey of Iowa farmers and a Bayesian logistic regression, finding that physical dependence and economic dependence are distinct dimensions of SOP in working landscapes and the addition of a measure beyond …

Modern science depends on computers, but not all scientists have access to the scale of computation they need. A digital divide separates scientists who accelerate their science using large cyberinfrastructure from those who do not, or who do not have access to the compute resources or learning opportunities to develop the skills needed. The exclusionary nature of the digital divide threatens equity and the future of innovation by leaving people out of the scientific process while over-amplifying the voices of a small group who have resources. However, there are potential solutions: recent advancements in public research cyberinfrastructure and resources developed …

Water Literacy In Drought-Prone Regions: Case Studies From Aurora, Colorado, Usa And Cape Town, Western Cape, South Africa, Meghan Mccarroll

Electronic Theses and Dissertations

Water managers around the world must reevaluate their approach to water security as challenges continue to grow. Supply-focused paradigms that aimed to capture, control, and commodify water resources are increasingly unreliable and often depend on environmentally and socially damaging practices. Of particular concern are regions experiencing climate shocks and aridification from rising global temperatures. In order to stretch limited water resources using equitable water policies, conservation programs, and alternative water sourcing, water managers must invest in a water literate citizenry. Water literacy is the culmination of water-related knowledge, attitudes, and behaviors. The benefits of a water literate citizenry abound, including …

Estimating Changing Marshland Habitat And Conservation Potential For Diamondback Terrapins (Malaclemys Terrapin) In New Jersey Under Climate Change, Jacqueline Ganter, Zachary Christman

School of Earth & Environment Departmental Research

The diamondback terrapin (Malaclemys terrapin), a brackish water turtle species native to the eastern United States, is under “special concern” in the state of New Jersey, due to decreasing habitat from development and changing climatic conditions. Diamondback terrapins reside in saline marshes and coastal wetlands and nest in sandy substrate, primarily beaches and dunes, in June and July. New Jersey is vulnerable to sea level rise, leaving diamondback terrapin habitats and nesting areas at risk of inundation under future climate scenarios, and, as the most densely populated state, subject to continual development pressures on potentially conservable land. Changing sea levels …

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 …

A Complex Record Of Last Interglacial Sea-Level History And Paleozoogeography, Santa Rosa Island, Channel Islands National Park, California, Usa, Daniel R. Muhs, Lindsey T. Groves, Kathleen R. Simmons, R. Randall Schumann, Scott A. Minor

United States Geological Survey: Staff Publications

Studies of marine terraces and their fossils can yield important information about sea level history, tectonic uplift rates, and paleozoogeography, but some aspects of terrace history, particularly with regard to their fossil record, are not clearly understood. Marine terraces are well preserved on Santa Rosa Island, California, and the island is situated near a major marine faunal boundary. Two prominent low-elevation terraces record the ~80 ka (marine isotope stage [MIS] 5a) and ~120 ka (MIS 5e) high-sea stands, based on U-series dating of fossil corals and aminostratigraphic correlation to dated localities elsewhere in California and Baja California. Low uplift rates …

New Geodetic Constraints On The Role Of Faults And Blocks Vs. Distribute Strain In The Nubia-Arabia-Eurasia Zone Of Active Plate Interactions, Semi̇h Ergi̇ntav, Michael Floyd, Demitris Paradissis, Hayrullah Karabulut, Philippe Vernant, Frederic Masson, Ivan Georgiev, Ali̇ Özgün Konca, Uğur Doğan, Robert King, Robert Reilinger

Turkish Journal of Earth Sciences

We present a broad view of present-day motions and deformations derived from uniform processing of GNSS observations within the Nubia-Arabia-Eurasia zone of plate interaction. The new observations we present provide a ~29% increase in the number of velocity determinations, a reduction in average station spacing from ~76 km to ~39 km, and an improvement in velocity uncertainties (for < 1 mm/year), from 180 to 578 sites compared to our prior published solution (Reilinger et al., 2006). We use these new constraints to better evaluate the role of faults and blocks in controlling the character of continental deformation within the zone of plate interactions. Simple elastic block models show that internal deformation of the region occurs in large part on mapped, seismically active fault systems, indicating elastic behavior of the seismogenic crust (above ~15 km). For example, eastern central Anatolia, an area of > ~126,000 km2, bounded by the North and East Anatolian Faults exhibits internal velocity differences of < 0.5 mm/year, indicating strain rates of < ~1.5 nanostrain/year. Geodetically constrained fault slip rates obtained from this simplified approach are comparable to geologic rates, indicating that major faults have controlled the recent geologic evolution of the region (i.e. 5?10 Myr). The pattern of present-day deformation, including increasingly fast motions towards the Hellenic trench, and the roughly simultaneous opening of all the major Mediterranean basins in the early Miocene with the slowing of the Nubia-Eurasia convergence, support conceptual models that foundering and rollback of the subducted Nubian slab beneath the Aegean is the primary mechanism responsible for present-day motion and internal deformation of the Anatolian-Aegean region.

Paleoseismology Of The Ganos Segment; The Western Extend Of The North Anatolian Fault (Turkey), Murat Ersen Aksoy, Mustapha Meghraoui, Matthieu Ferry, Zi̇yadi̇n Çakir, Gülsen Uçarkuş, Taylan Sançar, Mehmet Uğur Altin

Turkish Journal of Earth Sciences

The Ganos fault that ruptured on 9 August 1912 (Mw: 7.4) is the westernmost inland segment of the North Anatolian fault (NAF). Here, the Ganos fault is bounded at its two tips with offshore faults segments, in the Sea of Marmara to the east and the Gulf of Saros to the west in the North Aegean Trough. Therefore, the paleoseismology of the 45-km-long inland fault is of importance to the seismic hazard analysis related to offshore active faults and in particular for the seismic gap in the Marmara Region. Earlier studies have established an earthquake chronology for the western and …

Paleoseismology Of The Sürgü And Çardak Faults - Splays Of The Eastern Anatolian Fault Zone, Türkiye, Musa Balkaya, Hüsnü Serdar Akyüz, Süha Özden

Turkish Journal of Earth Sciences

The sinistral East Anatolian Fault Zone (EAFZ) and the dextral North Anatolian Fault Zone (NAFZ) are two important strike-slip faults that delimit the boundaries of the Anatolian plate. The north-south directed compressional forces in eastern Türkiye trigger the westward escape of the Anatolian plate along these prominent structures. This study aims to reveal the earthquake history of the Sürgü and Çardak faults, which are important fault segments that splay from the EAFZ. In this context, overall, four paleoseismologic trenches were dug, two trenches on the Sürgü Fault and two trenches on the Çardak Fault. Along the Sürgü Fault, at least …

Mapping For Accountability: Decolonizing Land Acknowledgment Initiatives, Salma Monani, Sarah E. Gilsoul

Environmental Studies Faculty Publications

What does it mean to map Indigenous presence onto lands that have been appropriated by settler colonial nation states? This chapter examines the challenges and potentials of re-inscribing Indigenous land relations through a digital mapping project, Indigenous Pennsylvania: Past, Present and Future. Situating itself within the growing scholarship of Indigenous cartographies, the chapter presents Indigenous Pennsylvania as an example of d-ecomedia, a shorthand we offer for ecomedia projects that foreground decolonial methodologies. Such methodologies prompt us to attend to a storied sense of Indigenous place-based relations through attention to Indigenous spatial and temporal modes of mediation.

Just Transition Litigation In Latin America: An Initial Categorization Of Climate Litigation Cases Amid The Energy Transition, Maria Antonia Tigre, Lorena Zenteno, Marlies Hesselman, Natalia Urzola, Pedro Cisterna-Gaete, Riccardo Luporini

Sabin Center for Climate Change Law

Just transition litigation is a novel field representing a sub-set of climate change litigation cases that is under-researched and studied. The report provides a novel comparative analysis of legal developments found in 20 just transition litigation cases in four Latin American countries and questions whether initiatives for achieving energy transformation in the region may have erred in failing to consider key just transition principles or dimensions, leading applicants to bring legal cases to claim their rights or demand more just solutions. The cases found – limited to the energy sector – not only question decarbonization policies or projects (in typical …

Modeling Monthly Actual Evapotranspiration: An Application Of Geographically Weighted Regression Technique In The Passaic River Basin, Felix Oteng Mensah, Clement Aga Alo

Department of Earth and Environmental Studies Faculty Scholarship and Creative Works

Actual evapotranspiration (ET) is perhaps the most difficult quantity to directly measure among the major water balance components. Because of the high cost and labor constraints associated with the direct measurement of ET, empirical data-driven modeling has frequently been used to estimate ET. Beyond the widely used traditional type regression that has the effect of producing ‘global’ parameter estimates, assumed to be uniform throughout an area, we utilized a more localized spatially non-stationary technique - the geographically weighted regression (GWR) - to estimate mean monthly ET in the Passaic River Basin (PRB). We identified the key environmental controls of ET …

Polytech To Polytek: Traditional Ecological Knowledge, Indigenous Science, And The Future Forward Polytechnic University, Cutcha Risling Baldy, Kaitlin P. Reed, Kayla Begay

Humboldt Journal of Social Relations

It is clear from Cal Poly Humboldt’s Polytechnic Prospectus that Traditional Ecological Knowledge (TEK) and Indigenous communities are key parts of what elevates Humboldt’s development of a polytechnic university for the next century. The prospectus demonstrates Humboldt's proposed framework for a different comprehensive polytechnic "will also be informed by Indigenous communities and ways of knowing, as many Native peoples have lived sustainably in their places since time immemorial” (19). There are many considerations when engaging with TEK, especially around sustainable use. It is also important that engagement with TEK and Indigenous science not only center knowledge sharing, but also how …

The purpose of this study is to reveal the factors that can classify type of aircraft damages such as none, minor and substantial in all-time incidents and accidents. ML algorithms with different configurations are applied for the classification process. The RFE and PCA are used to find the most …

Relationship Between Tree Canopy Cover, Impervious Surfaces, & Bird Biodiversity In Urban Parks In Nashville, Tennessee​, Colin Swanson, Darlene Panvini, Lydia Mitchell

Science University Research Symposium (SURS)

Bird diversity is an indicator of the overall biodiversity in urban green spaces. Identifying factors associated with urban green spaces that strongly influence bird biodiversity can inform the development and management of urban green spaces. Parks with larger areas of impervious surfaces were predicted to have lower bird diversity than those with more tree canopy coverage. This study used iTree Canopy to determine the percentage of tree canopy and impermeable surfaces for four different areas of urban parks in Nashville, Tennessee. Two parks were closer to the urban core and two were farther away. Tree canopy and impermeable surface cover …

Drivers Of Spatiotemporal Patterns Of Surface Water Inputs In A Catchment At The Rain-Snow Transition Zone Of The Water-Limited Western United States, E. Trujillo, J. Mcnamara

Geosciences Faculty Publications and Presentations

Spatial and temporal dynamics of rainfall and snowmelt (i.e., surface water inputs, SWI) control soil moisture, groundwater recharge, and streamflow at annual, seasonal, and event scales. In the rain-snow transition zone, comprising a large portion of the mountainous western United States, there is limited understanding of the sensitivity of spatiotemporal SWI dynamics across hydrologically variable water years (WYs). We modeled rainfall and snowpack dynamics in a small headwater catchment (1.8 km²) spanning the rain-snow transition in southwestern Idaho, USA, for two hydrologically distinct WYs (2011 and 2014). In wet WY 2011 and dry WY 2014, total precipitation drove …
