Use Of Unoccupied Aerial Vehicle (Drones) Based Remote Sensing To Model Platform Topography And Identify Human-Made Earthen Barriers In Salt Marshes, Joshua J. Ward

Masters Theses

Elevation is a foundational driver of salt marsh morphology. Elevation governs inundation and hydrological patterns, vegetation distribution, and soil health. Anthropogenic impacts at grand scales (e.g., rising sea levels) and local scales (e.g., infrastructure) have altered the elevation of the salt marsh surface, changing the topography and morphology of these ecosystems. This study establishes and assesses means to document and analyze these impacts using Unoccupied Aerial Vehicle (UAV) based remote sensing to model platform topography. This thesis’s first and primary study presents and compares methods of producing high-resolution digital terrain models (DTMs) with UAV-based Digital Aerial Photogrammetry (DAP) and Light …

Automated Identification And Mapping Of Interesting Mineral Spectra In Crism Images, Arun M. Saranathan

Doctoral Dissertations

The Compact Reconnaissance Imaging Spectrometer for Mars (CRISM) has proven to be an invaluable tool for the mineralogical analysis of the Martian surface. It has been crucial in identifying and mapping the spatial extents of various minerals. Primarily, the identification and mapping of these mineral spectral-shapes have been performed manually. Given the size of the CRISM image dataset, manual analysis of the full dataset would be arduous/infeasible. This dissertation attempts to address this issue by describing an (machine learning based) automated processing pipeline for CRISM data that can be used to identify and map the unique mineral signatures present in …

Modeling Spatial Distributions Of Tidal Marsh Blue Carbon Using Morphometric Parameters From Lidar, Bonnie Turek

Masters Theses

Tidal marshes serve as important “blue carbon” ecosystems that accrete large amounts of carbon with limited area. While much attention has been paid to the spatial variability of sedimentation within salt marshes, less work has been done to characterize spatial variability in marsh carbon density. Driven by tidal inundation, surface topography, and sediment supply, soil properties in marshes vary spatially with several parameters, including marsh platform elevation and proximity to the marsh edge and tidal creek network. We used lidar to extract these morphometric parameters from tidal marshes to map soil organic carbon (SOC) at the meter scale. Fixed volume …

The Global Impact Of The Antarctic Ice Sheet In A Warming World: Using Numerical Modeling And Critical Physical Geography To Assess Climate Change, Sea Level Rise, And Climate Justice

Doctoral Dissertations

Anthropogenic climate change is causing disruptions in the Earth system with negative ramifications for life on our planet. Increasing atmospheric greenhouse gas concentrations lead to accumulated heat content and the cryosphere is one of the earliest places to show changes in response to rising temperatures. The melting of the Antarctic Ice Sheet will have myriad effects on global climate due to interconnections and feedbacks between the ice sheet, ocean, and atmosphere. In this dissertation I use numerical modeling and critical geography to assess future climate conditions that occur in response to changes in Antarctic Ice Sheet melt as well as …

Making The Old City: Life Projects And State Heritage In Rhodes And Acre, Evan Taylor

Doctoral Dissertations

The “old city,” a widely recognizable category of urban space, has long been a locus of development projects, state monitoring, and mass tourism, while also being home to resident communities. This dissertation explores the intersections of community life and state-driven heritage projects in the Old Town of Rhodes, in the Greek Dodecanese, and the Old City of Acre (‘Akka), a Palestinian community in northern Israel/Palestine. Both old cities are UNESCO World Heritage sites and subjects of intense state-supported tourism development. However, their resident populations and their built environments, which coalesced mainly under Crusader and Ottoman rule, challenge the authorized heritage …

Residents' Perspectives Of Young, Street-Facing Trees: Three Cases From Legacy Cities With Active Tree Planting Initiatives, Alicia Coleman

Doctoral Dissertations

Organized tree planting initiatives are underway in cities across the world in order to expand tree canopy cover, combat environmental threats, and create more livable places for urban residents. Trees along and near city streets provide a number of services for residents; however, evidence from environmental design and landscape preference research suggests that the perceptual effect of large-statured, mature trees may differ from small-statured, young trees. This dissertation explored these differences in three studies based in communities with active tree planting initiatives. Chapter 2 compares tree preferences from a hypothetical tree planting initiative to preferences for trees in other settings …

Perceptions Of Historical Climate Change And Park Policy: The Impact On The Fremont Cottonwood In Zion National Park, Kathleen Kavarra Corr

Doctoral Dissertations

Despite its “natural” appearance and the Organic Act 1916 mandate for preservation of the natural environment in National Parks, the Virgin River as it flows through Zion National Park’s Zion Canyon was transformed through massive flood control re-engineering projects in the 1930s. The armoring of the river has had significant impacts on riparian vegetation, particularly on the stands of native Fremont Cottonwood trees that once filled the narrow valley. What was the motivation for this massive flood control project carried out in an arid region with less than 15 inches of rain per year? This dissertation explores the motivations which …

Reclaiming The Future Through Small-Scale Agriculture: Autonomy And Sustainability In The Caribbean, Dana M. Conzo

Doctoral Dissertations

My dissertation, “Reclaiming the future through Small-Scale Agriculture: Autonomy and Sustainability in the Caribbean,” is a political-economic analysis of land politics, foodscapes and foodsheds, and small-scale agricultural activities in plantation economies on the Caribbean island of St Kitts. Using ethnographic and geographic methods, such as participant observation, interviews, social network analysis, and foodshed mapping, I investigate the cultural and economic niche of local farmers, documented and analyzed the island’s foodshed, and provide a historical and economic background of St Kitts to link historical processes to contemporary spatial organization and agricultural practices. I consider the complexities of food inequalities and food …

Algorithm Performance On The Estimation Of Cdom And Doc In The North Slopes Of Alaska, Monica Weisenbach

Masters Theses

Use of satellite imagery makes environmental monitoring easy and convenient with little of the logistics involved in planning sampling campaigns. Colored dissolved organic matter (CDOM) is an important component to track as a proxy for the large pool of dissolved organic carbon (DOC). In a world contending with the looming issue of global climate change, the ability to investigate the carbon cycle of inland to coastal environments allows for examination of the magnitude of carbon flowing through the system and potential changes over years. The Arctic region is a critical area for climate change impacts but is a difficult landscape …

Care Work In Chile’S Segregated Cities, Manuel Garcia

Doctoral Dissertations

This project combines diverse theoretical and methodological tools to examine the relationship between space and care work in Chile. The chapters are stand-alone articles that come together to tell a single story. The social production of urban space has marginalized thousands of female caregivers from the labor market as Chile’s care system unravels. I argue that community caregiving could simultaneously improve the conditions of caregivers and dependents. Chapter 1 examines the role of residential segregation in reproducing Chile’s meager female labor market participation rates. I use spatial and econometric analysis to show that the social forces that segregate Santiago create …

Monitoring Mammals At Multiple Scales: Case Studies From Carnivore Communities, Kadambari Devarajan

Doctoral Dissertations

Carnivores are distributed widely and threatened by habitat loss, poaching, climate change, and disease. They are considered integral to ecosystem function through their direct and indirect interactions with species at different trophic levels. Given the importance of carnivores, it is of high conservation priority to understand the processes driving carnivore assemblages in different systems. It is thus essential to determine the abiotic and biotic drivers of carnivore community composition at different spatial scales and address the following questions: (i) What factors influence carnivore community composition and diversity? (ii) How do the factors influencing carnivore communities vary across spatial and temporal …

China's Urbanization Model And Its Practice In Western China: A Case Study Of Urbanization In Xining, Qinghai, Xin Li

Doctoral Dissertations

China’s unprecedented urban expansion has drawn extensive scholarly and public attention. The mechanisms and fundamental changes that the urbanization process has brought to Chinese cities have been heatedly discussed in the academic realm. However, research attention has been largely paid to the eastern coastal region. Western Chinese cities in contrast, although they have been catching up with the economic and urban development with two-digit growth in the past two decades, have received relatively little attention. This dissertation analyzes the driving forces, characteristics, and impacts of this recent urban expansion in western Chinese cities. In particular, it focuses on Xining, a …

Negotiating Space: Spatial Violation On The Early Modern Stage, 1587-1638, Gregory W. Sargent

Doctoral Dissertations

Recent criticism proves the malleability of theatrical space as a lens through which the discussion of Renaissance drama proliferates. Negotiating Space works towards the articulation of the importance of space in the representational mimesis of performance by examining moments of violence, violation, misuse, and misappropriation. I draw a connection between the lived, material sites of the plays’ action and the ideological import of representing those spaces dramatically using a focus on violation. Though much good scholarship exists detailing London-centric approaches to dramatic space, this study discursively reifies identifiable staged spaces to connect with the lives of theatrical patrons no matter …

An Assessment Of Four Selected Communities Along The Appalachian Trail In Relation To Emile Benton Mackaye's Original Vision Of Regional Planning, Jessica Ann Schottanes

Masters Theses

Planner, conservationist, forester, and geographer Emile Benton MacKaye envisioned a revolutionary, extensive foot trail that would promote the interaction between communities throughout the United States' distinctive eastern region. His 1921 plan for the Appalachian Trail (A.T.) focused on balancing the basic requirements for life in and out of the urban context by developing an ‘indigenous’ environment and developmental mold (Bower 1962, 372). However, almost a century has passed, and MacKaye's approach to the planning process, organization, environmental development, and the rural economy remains hidden beneath the mountain forest canopy extending from Maine to Georgia.

Four of the forty-nine designated communities …

Firesafe: Designing For Fire-Resilient Communities In The American West, Brenden Baitch

Masters Theses

The perception that wildfires are completely preventable has caused many structures and communities to be built in locations that will inevitably experience an uncontrollable fire event, risking human lives and infrastructure. Modification of built environments into fire-adapted communities has been explored in this thesis, through multiple strategies. Central to this analysis is the idea that sustainable human developments could adopt a form of biomimicry and indigenous design informed by the adaptions of plants, animals, and native groups that endure and even thrive with regular cycles of fire. This possibility has been assessed through the scope of fire adaptation strategies available …

Liberation And Gravy: An Engaged Ethnography Of Queer And Trans Power In Georgia, Elias Capello

Doctoral Dissertations

This dissertation aims to better understand how self-identified trans activists in Atlanta, Georgia find and build community, by using queer and Black feminist community based methodologies such as participant observation, ethnographic interviews, participatory mapping, and auto-ethnography. In particular, I ask 1) How do trans people find and build community, safety, and understanding? 2) How do transgender activists create and enact place making that does not rely on policing and privatization? To create and maintain safety for wealthy communities in Atlanta, Georgia, systems of policing and privatization are increasing. Although developers, city council members, and legislators promote Atlanta, Georgia as a …

How Can Employers Contribute To Reducing Commuter-Generated Carbon Emissions? Evaluating Employer-Provided Commuter Benefits In Cambridge, Ma, Mary Richards

Masters Theses

Encouraging a more sustainable commuter mode shift and improving urban transportation systems have the potential to reduce anthropogenic greenhouse gas emissions (GHGs), a major contributor to climate change. Replacing some single-occupancy vehicle (SOV) trips with alternative modes of transportation, such as public transit, walking, or bicycling, represents one approach to begin reducing transportation-related emissions. Collectively, these shifts in transportation patterns would help to reduce the negative social, economic, and environmental costs associated with high rates of personal vehicle use. Employer-provided benefits programs have the potential to influence commuter behavior by making sustainable, alternative commuting choices a more convenient and economically …

Enforcing Higher Standards For Flood Hazard Mitigation In Vermont, Tamsin Flanders

Masters Theses

The state of Vermont faces increasing risk of costly damage from catastrophic flooding events as climate change increases the frequency of heavy rains and cumulative precipitation. In addition to increasing flood inundation risk, extreme precipitation events are leading to high rates damage from fluvial erosion—erosion caused by the force of floodwater and the materials it carries. As in all U.S. states, flood hazard governance in Vermont is shared by multiple levels of government and involves a complex compliance model that relies on local governments to regulate private property owners to achieve community, state, or federal goals.

To encourage municipalities to …

Understanding Agrihoods: An Exploration Into The Growing Trend Of Farm-To-Table Communities Across The United States, Benjamin Breger

Masters Theses

Agrihoods are a recent trend in real estate development that integrate agricultural amenities - such as working farms, orchards, or community gardens - into residential or mixed-use communities. As an emergent trend, agrihoods have the potential to enhance farmland preservation and local and regional food systems, making them a ripe area for research. However, very little scholarly research has been carried out to characterize, contextualize or evaluate agrihood developments. Thus far, the development model has primarily been detailed in popular media sources. This thesis serves as a baseline study that seeks to understand how neighborhood food systems operate within agrihood …

Modeling Fire Observations, Ignition Sources, And Novel Fuels To Understand Human Impacts On Fire Regimes Across The U.S., Emily Fusco

Doctoral Dissertations

Fire is a natural, and necessary, component of many ecosystems. However, people are changing the spatial and temporal distribution of wildfires in the U.S. at great economic and ecological costs. My dissertation addresses the impacts of humans on U.S. fires both through the introduction of ignition sources and flammable grasses. Further, I evaluate fire datasets that are widely used to investigate these phenomena over large spatial and temporal scales. Finally, I create an aboveground carbon map that can be used to estimate the potential carbon loss consequences in western U.S. ecosystems most at risk to fire. My work shows that …

Planning For Industrial Land And Industrial Jobs: An Evaluation Of New York City's Industrial Business Zone Program, Jennifer Davis

Masters Theses

In recent years, industrial preservation policies, which aim to preserve urban industrial activity and industrial employment often through the preservation of industrial land, have emerged as a flashpoint in cities across the country that have implemented these policies. While critics contend that industrial preservation policies amount to smokestack chasing in “post-industrial” cities like New York City, industrial preservationists argue that such policies help to preserve well-paying, middle-class jobs and thus represent a tool to mitigate rising income inequalities in cities. Despite considerable attention to these policies, minimal research has evaluated the effectiveness of industrial preservation policies as land use and …

A Study On Modelling Spatial-Temporal Human Mobility Patterns For Improving Personalized Weather Warning, Yue Xu

Masters Theses

Understanding human mobility patterns is important for severe weather warning since these patterns can help identify where people are in time and in space when flash floods, tornados, high winds and hurricanes are occurring or are predicted to occur. A GIS (Geographic Information Science) data model was proposed to describe the spatial-temporal human activity. Based on this model, a metric was designed to represent the spatial-temporal activity intensity of human mobility, and an index was generated to quantitatively describe the change in human activities. By analyzing high-resolution human mobility data, the paper verified that human daily mobility patterns could be …

Rethinking The Creative Economy: The Diverse Economies Of Artists And Artisans In Rural Massachusetts, Abby Irene Templer Rodrigues

Doctoral Dissertations

This dissertation explores the contours of artistic economic activity through participatory action research conducted with artists and artisans in the Greater Franklin County, Massachusetts. The creative economy has drawn significant attention over the past ten years as a principle economic sector that can stimulate the redevelopment of post-industrial cities. However, dominant creativity–based development strategies tend to cater to the tastes of an economically privileged, and implicitly white, “creative class,’ leading to gentrification and social exclusion based on race, ethnicity, class, and gender. These exclusions also apply to artists and artisans, occupational groups whose economic activity and needs have been paradoxically …

In Theory, There's Hope: Queer Co-(M)Motions Of Science And Subjectivity, Cordelia Sand

Masters Theses

Given the state of the planet at present —specifically, the linked global ecological and economic crises that conjure dark imaginings and nihilistic actualities of increasing resource depletion, poisonings, and wide-scale sufferings and extinctions—I ask What might we hope now? What points of intervention offer possibility for transformation? At best, the response can only be partial. The approach this thesis takes initiates from specific pre-discursive assumptions. The first understands current conditions as having been produced, and continuing to be so, through practices that enact and sustain neoliberal relations. Secondly, these practices are expressive of a subjectivity tied to a Cartesian worldview, …

Improving Small Community Flood Resilience: The Multiple Strategies Of Watershed Partnerships, Nicole Gillett

Masters Theses

Flooding in New England is often seen as a coastal concern, but inland, in the mountainous rural communities of New England, river floods present serious threats to communities and livelihoods. Recent large storm events such as Tropical Storm Irene, and rising concerns over climate change, have catalyzed conversations over the vulnerability of communities across inland New England to flooding. This thesis examines two very different watershed organizations in New England; the White River Partnership and Deerfield Creating Resilient Communities. Both are working towards flood resilience in their communities. My approach is not to judge “best practices” or to evaluate what …

Assembling Creative Cities In Seoul And Yokohama: Rebranding East Asian Urbanism, Changwook Kim

Doctoral Dissertations

By investigating institutional and cultural practices as well as the consequences of the creative industry-led development policy in Yokohama, Japan and Seoul, South Korea, this dissertation critically reexamines the key rationales of creative economy-driven urban development and considers social costs and tensions between the state, capital and citizens that are embedded within creative city policy discourses and practices. This dissertation intervenes in the conventional understandings, which consider the influx of neoliberalism as the key to explain the rapid global circulation of creative city policy, typically based on cities in the West. By considering the policy transfer as endless processes of …

Of Wolves, Hunters, And Words: A Comparative Study Of Cultural Discourses In The Western Great Lakes Region, Tovar Cerulli

Doctoral Dissertations

This study is a description, interpretation, and comparison of talk about wolves. The study is based on diverse data—including in-depth interviews, instances of public talk, government documents, and letters to the editor—gathered over three years. An overarching research question guides the study: How do hunting communities create and use discourses concerning wolves? The study is situated within the ethnography of communication and, more specifically, the framework of cultural discourse analysis. The study employs cultural discourse analysis methods and concepts to describe and develop interpretations of how participants render wolves symbolically meaningful, and of beliefs and values underpinning such meanings. One …

Rethinking The Creative Economy: Participatory Action Research With Artists And Artisans In The Greater Franklin County, Leo L. Hwang

Doctoral Dissertations

The Rethinking the Creative Economy Project utilized a participatory action research methodology with an asset-based approach to examine the noncapitalist practices of artists and artisans in the context of a community economy. By privileging noncapitalist practices, the contributions of artists and artisans can be assigned value, where no or little value was assigned before. In the context of creative economy development, by ignoring the diverse economy of artists and artisans there is a real danger of continuing a narrative of deficits and a lack of agency. However, artists and artisans are crucial to the viability of a creative economy because …

Urban Redevelopment Through City-University Partnerships: Envisioning An Education District In Springfield, Massachusetts, Mohammed Abdelaal

Masters Theses

This thesis examines the impact of planning a potential new urban university campus in Springfield, Massachusetts on the city’s long term goals for urban revitalization. By exploring a collaborative and community-oriented process for higher-educational development, I propose a dynamic model that could work as a catalyst for urban revitalization.

The study will focus on the following: developing partnerships between the city of Springfield (government, community, local groups) and major educational institutions (such as the University of Massachusetts system); identifying potential sites suitable for the anticipated urban/mixed-use campus or compound; and studying and analyzing the forces within the city (neighborhoods around …

New Wenzhou: Migration, Metropolitan Spatial Development And Modernity In A Third-Tier Chinese Model City, Sainan Lin

Doctoral Dissertations

Migration has asserted great influence on urban spatial structure, especially during China’s recent waves of rural-to-urban migration. This dissertation focuses on Wenzhou, a third-tier Chinese city that served as a national model for the re-introduction of small-scale private enterprise in the 1990s. Wenzhou’s economic success generated migration that has served as a catalyst for new forms of urbanization in which migrants play a central role. I aim to examine and understand the distribution patterns of migrant settlements, their changes over time and the ways that the formation of these settlements has impacted emerging urban form. There are two primary components …
