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 …

Why It Matters: The Tourist/Traveller Dichotomy In The Context Of Pandemic-Era Overtourism, Kelley A. Mcclinchey

TTRA Canada 2023 Conference

This research investigates the traveller/tourist dichotomy through a discourse analysis of online blogs and travel writing in the context of pandemic-era overtourism. Results indicate that travellers/tourists are perceived in ways that validate one over the other, yet both are intricately weaved within the neocolonial structures of tourism, grounded in imperialism and the power dynamics visitors have on a place.

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 …

Correlational Analysis Of Mammals And Residential Land Use: Amherst, Ma, Ella Gutkowski

Massachusetts GIS Day

Mammal diversity varies in different types of land uses. Residential land use oftentimes interferes with the natural occurrence of mammal species. This study conducts a correlational analysis using camera trap data from Excel and land use data in GIS to uncover whether humans have disrupted mammal occurrence in residential land use areas in Amherst, MA. Results reveal that human activity in residential land use areas in Amherst did not strongly influence the occurrence of these mammals.

Georeferencing The Macconnell Aerial Photo Collection, Alex Heilmann, Matthew Martin, Camille Barchers, Forrest J. Bowlick, Rebecca M. Seifried

Massachusetts GIS Day

In the 1950s, Professor William P. MacConnell from the University of Massachusetts Forestry Department began working with his students to map the land cover in Massachusetts via the state’s earliest aerial photography program. These individual photographs are now part of the Special Collections and University Archives at the University of Massachusetts Amherst Libraries, and although they have been digitized and made available online, they have not yet been georeferenced.

In Spring 2021, our team (Alex and Matthew) began manually georeferencing the photos in ArcMap 10.8 software onto USGS 2019 color orthoimagery of Massachusetts available from MassGIS. Ideal ground control points …

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 …

Hourly Surface Meltwater Routing For A Greenlandic Supraglacial Catchment Across Hillslopes And Through A Dense Topological Channel Network, Colin J. Gleason, Kang Yang, Dongmei Feng, Laurence C. Smith, Kai Liu, Lincoln H. Pitcher, Vena W. Chu, Matthew G. Cooper, Brandon T. Overstreet, Asa K. Rennermalm

Civil and Environmental Engineering Faculty Publication Series

Recent work has identified complex perennial supraglacial stream and river networks in areas of the Greenland Ice Sheet (GrIS) ablation zone. Current surface mass balance (SMB) models appear to overestimate meltwater runoff in these networks compared to in-channel measurements of supraglacial discharge. Here, we constrain SMB models using the hillslope river routing model (HRR), a spatially explicit flow routing model used in terrestrial hydrology, in a 63 km(2) supraglacial river catchment in southwest Greenland. HRR conserves water mass and momentum and explicitly accounts for hillslope routing (i.e., flow over ice and/or firn on the GrIS), and we produce hourly flows …

Who Bears The Burden? Racial Disparities In Confirmed Cases Of Covid-19 In The Greater Boston Area, Leija Helling

Massachusetts GIS Day

Documenting racial disparities in the spread of COVID-19 is crucial to bettering public health. In the Boston area, non-white and Black communities are significantly overrepresented in areas of high confirmed COVID-19 prevalence. Areas where high prevalence is clustered (“hot spots”) have disproportionate shares of non-white and Black residents, and the disparities are statistically significant. These results confirm marked COVID-19 racial disparities in Boston.

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 …

The Capacity Building Workshops on Nature-Culture Linkages in Heritage Conservation (CBWNCL), held at the University of Tsukuba in Japan, gather Asia-Pacific heritage professionals with the aim of creating a platform of mutual-learning and exchange between the culture and nature sectors. In the first workshop on Agricultural Landscapes, from 14 case studies, 5 showed natural protected areas in tense relations with their rural landscape surroundings. However, these agricultural landscapes are essential for protecting natural values, as they form part of their larger ecosystems. In the second workshop on Sacred Landscapes, from 16 case studies, 5 case studies were also …

Panel 3 Paper 3.1: Participatory Planning And Monitoring Of Protected Landscapes: A Case Study Of An Indigenous Rice Paddy Cultural Landscape In Taiwan, Kuang-Chung Lee

ISCCL Scientific Symposia and Annual General Meetings // Symposiums scientifiques et assemblées générales annuelles de l'ISCCL // Simposios científicos yy las Asambleas Generales Anuales

Landscapes can be regarded as ‘a culture–nature link.’ Many examples of ‘living’ landscapes in the world are rich in natural and cultural values and have proven sustainable over centuries because of their maintenance by local communities. Satoyama, a traditional socio-ecological production landscape, provides a functional linkage between paddy fields and the associated environment with many ecosystem services. The idea of landscape conservation and paddy field revitalization was introduced into Taiwan’s amended Cultural Heritage Preservation Act in 2005 as a new legal instrument entitled ‘Cultural Landscape.’ To help stakeholders from governmental authorities and local communities apply this new instrument, this action …
