Measuring Global Multi-Scale Place Connectivity Using Geotagged Social Media Data, Zhenlong Li, Xiao Huang, Yuqin Jiang, Yago Martin, Huan Ning, Michael E. Hodgson, Xiaoming Li

Faculty Publications

Shaped by human movement, place connectivity is quantified by the strength of spatial interactions among locations. For decades, spatial scientists have researched place connectivity, applications, and metrics. The growing popularity of social media provides a new data stream where spatial social interaction measures are largely devoid of privacy issues, easily assessable, and harmonized. In this study, we introduced a global multi-scale place connectivity index (PCI) based on spatial interactions among places revealed by geotagged tweets as a spatiotemporal-continuous and easy-to-implement measurement. The multi-scale PCI, demonstrated at the US county level, exhibits a strong positive association with SafeGraph population movement records …

Resettlement Capacity Assessments For Climate Induced Displacements: Evidence From Ethiopia, Solomon Zena Walelign, Susan L. Cutter, Paivi Lujala

Faculty Publications

Climate change migration is increasing and necessitates a re-examination of resettlement planning and processes. Although evidence-based selection of host places would improve climate change resettlement outcomes, few methods for the selection of host communities exist. Consequently, the information base on which most resettlement programs select a host place is often inadequate. This article proposes an empirical methodology to assess resettlement capacity. The methodology uses a hierarchical aggregation approach, where resettlement capacity indicator values are aggregated first into sub-dimension resettlement capacity scores, then further into dimension resettlement capacity scores, and finally into an overall resettlement capacity index. The aggregation allows for …

Projections Of Large-Scale Atmospheric Circulation Patterns And Associated Temperature And Precipitation Over The Pacific Northwest Using Cmip6 Models, Graham Patrick Taylor

Dissertations and Theses

Projections of 500 hPa geopotential height (Z500) patterns over the Pacific Northwest of North America and their associated surface temperature, precipitation, and frequency of occurrence are assessed using models from the 6th phase of the Coupled Model Intercomparison Project (CMIP6). The self-organizing maps approach is applied to reanalysis data from the Modern-Era Retrospective Analysis for Research and Applications, version-2 (MERRA-2) to cluster daily Z500 anomalies into 12 representative patterns that span the range of historical circulation patterns. CMIP6 data for daily Z500 anomalies are mapped to each node for historical and end of century global warming experiments, and the resulting …

Using Suitability Modelling To Determine Wildfire Ignition Risk A Case Study Of The Adirondack State Park, Dakota James Bailey

Theses - ALL

The study area centers around a 6 million acre protected area in upstate New York known as the Adirondack State Park. Spatial data are gathered and manipulated, then input into the ArcGIS Pro suitability modeler tool to construct several wildfire ignition risk models, as well as a wildfire spread risk model. Upon comparing these ignition models, contextual conclusions are formed on areas of greatest ignition risk pertaining to the individual models. The wildfire ignition risk models are overlayed with the spread risk model, to assess which areas are most likely to facilitate initial ignition and subsequent spread. Ultimately, it appears …

Running With The Land: Racial Capitalism, Restrictive Covenants, And The Pre-Redlining Roots Of The Private Real Estate Market In Syracuse, New York, Michael Thomas Kelly

Theses - ALL

This thesis locates the roots of the private U.S. real estate market, and racially segregated housing geographies, within a broader, multi-century project of establishing, racializing, and spatializing private property in land. Using archival methods, I examine and directly connect late 18th century land speculation and settlement, early 20th century real estate capitalist class formation, and the construction of all-white suburban sub-divisions based on racially restricted covenants. I investigate the city of Syracuse – a small, post-industrial city in Upstate New York on unceded Onondaga Nation land and one of the most racially segregated cities in the United States. I argue …

Beetles Or Bureaucrats? Reconsidering The United States' Failure To Stop Dutch Elm Disease, Emily Bukowski

Dissertations - ALL

In this dissertation, I analyze the failure of the United States to address the Dutch elm disease (Ophiostoma ulmi) epidemic that affected American elm (Ulmus americana) across the country. The disease, a fungus carried by beetles between trees, was introduced in 1930 in New York City and slowly spread across the Northeast United States and beyond. A federal program to save the elm trees was in place from 1930-1952. I use archival documents to create a narrative describing the management of the disease by the Bureau of Entomology and Plant Quarantine, the division of the United States Department of Agriculture …

Climate change adaptation responses are being developed and delivered in many parts of the world in the absence of detailed knowledge of their effects on public health. Here we present the results of a systematic review of peer-reviewed literature reporting the effects on health of climate change adaptation responses in low- and middle-income countries (LMICs). The review used the 'Global Adaptation Mapping Initiative' database (comprising 1682 publications related to climate change adaptation responses) that was constructed through systematic literature searches in Scopus, Web of Science and Google Scholar (2013-2020). For this study, further screening was performed to identify studies from …

A Geospatial And Statistical Analysis Of Dropout In Louisiana Public High Schools, Michael D. Stein

LSU Master's Theses

Students dropping out of high school is a nationwide problem, plaguing communities and often greatly reducing the prospects of a quality life for those students who do not complete their high school educations. Louisiana consistently has among the highest public high school dropout rates in the United States, and often the highest. This geospatial and statistical study aims to identify the factors that correlate with high school dropout in Louisiana public high schools, specifically, and to produce detailed maps of the dropout rates across the state to identify the schools most afflicted.

Environmental Perception In Colombia's Páramo Protected Areas, Juliana Delgado

LSU Master's Theses

This thesis analyzes the gap between farmers' environmental perceptions in Téquita, a small village in Colombia, and the definition of protected areas has led to a conflict for the use of natural resources. I examine if the protected area's policies have dealt with the social and ecological issues in the páramos and recognized the social construction of the landscape, farmers' identities, and their interpretations about work and land. The case study focuses on Güina High Mountain in the Guantiva-La Rusia páramo complex, which recently the Colombian government declared as a protected area. In light of anthropologist Tim Ingold's meaning of …

The goal of the EXport Processes in the Ocean from RemoTe Sensing (EXPORTS) field campaign is to develop a predictive understanding of the export, fate, and carbon cycle impacts of global ocean net primary production. To accomplish this goal, observations of export flux pathways, plankton community composition, food web processes, and optical, physical, and biogeochemical (BGC) properties are needed over a range of ecosystem states. Here we introduce the first EXPORTS field deployment to Ocean Station Papa in the Northeast Pacific Ocean during summer of 2018, providing context for other papers in this special collection. The experiment was conducted with …

Rowing Concerns: Collaborative Governance And Stakeholder Determination In The Central Oregon's Deschutes Basin, Noel Vineyard

Dissertations and Theses

In 2019, a coalition of irrigation districts in central Oregon's Deschutes Basin submitted the Deschutes Basin Habitat Conservation Plan to the US Department of Fish and Wildlife. This Habitat Conservation Plan purported to have been constructed through a collaborative governance structure between the irrigation districts and various community stakeholders who all had interests in basin management, however segments of the Basin's river recreation community began to raise concerns that their voices were not included. The purpose of this research was to investigate how stakeholder status in the Deschutes Basin is created through collaborative water governance processes like development of the …

Faculty Publications

The satellite validation navy tool (SAVANT) was developed by the Naval Research Laboratory to help facilitate the assessment of the stability and accuracy of ocean color satellites, using numerous ground truth (in situ) platforms around the globe and support methods for match-up protocols. The effects of varying spatial constraints with permissive and strict protocols on match-up uncertainty are evaluated, in an attempt to establish an optimal satellite ocean color calibration and validation (cal/val) match-up protocol. This allows users to evaluate the accuracy of ocean color sensors compared to specific ground truth sites that provide continuous data. Various match-up constraints may …

The Sustainability-Peace Nexus In Crisis Contexts: How The Rohingya Escaped The Ethnic Violence In Myanmar, But Are Trapped Into Environmental Challenges In Bangladesh, Saleh Ahmed, William Paul Simmons, Rashed Chowdhury, Saleemul Huq

Global Studies Faculty Publications and Presentations

Because of ethnic and cultural violence in Myanmar, approximately a million Rohingya fled to neighboring Bangladesh starting from August 2017, in what the UN has called a “textbook example of ethnic cleansing”. Those arriving in Bangladesh were able to escape decade-long ethnic violence in Myanmar, but the Rohingya’s immediate destination, Cox’s Bazar district is one of the most climate-vulnerable and disaster-prone areas in Bangladesh. Currently, they have been subjected to extreme rainfalls, landslides, and flashfloods. With the COVID-19 pandemic, they continue to face fear and further marginalization in resource-constrained Bangladesh, as well as increased vulnerability due to tropical cyclones, flashfloods, …

How To Resolve Channel Travel Time Errors In The Tr-55 Worksheet Using Arc Hydro Tools, Hec-Geohms And Hec-Hms, Philip A. Adalikwu, Suzette R. Burckhard

Civil and Environmental Engineering Reports and Manuals

This tutorial is an illustration of a stepwise procedure for resolving errors in calculated channel travel times that occur when processing watershed parameters in HEC-GeoHMS. Channel travel time errors occur when a GIS-defined channel slope value during preprocessing of the Digital Elevation Data (DEM) is zero or negative (Adalikwu, 2021). The tutorial is intended to assist a relatively experienced ArcMap user resolve channel travel time errors that are documented in the TR55 Worksheet. Particularly, this tutorial is useful if the Muskingum method is selected by the watershed modeler as the river routing method. The K parameter value in the Muskingum …

Deep Learning Reveals Extent Of Archaic Native American Shell-Ring Building Practices, Dylan Davis, Gino Capsari, Carl P. Lipo, Matthew Sanger

Anthropology Faculty Scholarship

In the mid-Holocene (5000 - 3000 cal B.P.), Native American groups constructed shell rings, a type of circular midden, in coastal areas of the American Southeast. These deposits provide important insights into Native American socioeconomic organization but are also quite rare: only about 50 such rings have been documented to date. Recent work using automated LiDAR analysis demonstrates that many more shell rings likely exist than are currently recorded in state archaeological databases. Here, we use deep learning, a form of machine intelligence, to detect shell ring deposits and identify their geographic range in LiDAR data from South Carolina. We …

Trends In Land Surface Phenology Across The Conterminous United States (1982-2016) Analyzed By Neon Domains, Liang Liang, Geoffrey M. Henebry, Lingling Liu, Xiaoyang Zhang, Li-Chih Hsu

Geography Faculty Publications

Tracking phenological change in a regionally explicit context is a key to understanding ecosystem status and change. The current study investigated long-term trends of satellite-observed land surface phenology (LSP) in the 17 National Ecological Observatory Network (NEON) domains across the conterminous United States (CONUS). Characterization of LSP trends was based on a high temporal resolution (3-d) time series of the two-band enhanced vegetation index (EVI2) derived from a long-term data record (LTDR) of the Advanced Very High Resolution Radiometer (AVHRR) and the Moderate Resolution Imaging Spectroradiometer (MODIS). We identified significant trend patterns in LSP and their seasonal climate and land …
