Different Stages Of Urbanization Lead To Cropland Loss: Geospatial Data Analysis In A Global Rural-Urban Continuum Perspective, Xiyu Li, Le Yu

I-GUIDE Forum

Rapid urbanization has resulted in widespread loss of cropland, but the spatial-temporal patterns and key stages of this transformation have not been clearly understood. In this study, we mapped cropland loss caused by urban expansion in rural-urban continuum since 2000 based on multiple global land maps. Results show a total 3.35 × 10⁶ ha cropland loss resulting from urban expansion and about 70 % of this land use change occurred in Asia. However, there is a trend of reducing cropland loss area caused by urbanization over the years. In a detailed view of urbanization stages, most cropland losses occurred …

Large-Scale Google Street View Images For Urban Change Detection, Fangzheng Lyu, Xinlin Ma, Yan Song, Eric Zhu, Shaowen Wang

I-GUIDE Forum

Urbanization has entered a new phase characterized by urban changes occurring at a micro-scale and “under the roof”, as opposed to external modifications. These changes, known as urban retrofitting, involve the incorporation of novel technologies or features into pre-existing systems to promote sustainability. Given the limitations of remote sensing images in identifying such urban changes, novel tools need to be developed for detecting urban retrofitting. In this study, we first build a pipeline to collect large-scale time-series urban street view images from Google Street View in Mecklenburg County, North Carolina. And we examine the feasibility of utilizing the acquired dataset …

Reducing Uncertainty In Sea-Level Rise Prediction: A Spatial-Variability-Aware Approach, Subhankar Ghosh, Shuai An, Arun Sharma, Jayant Gupta, Shashi Shekhar, Aneesh Subramanian

I-GUIDE Forum

Given multi-model ensemble climate projections, the goal is to accurately and reliably predict future sea-level rise while lowering the uncertainty. This problem is important because sea-level rise affects millions of people in coastal communities and beyond due to climate change's impacts on polar ice sheets and the ocean. This problem is challenging due to spatial variability and unknowns such as possible tipping points (e.g., collapse of Greenland or West Antarctic ice-shelf), climate feedback loops (e.g., clouds, permafrost thawing), future policy decisions, and human actions. Most existing climate modeling approaches use the same set of weights globally, during either regression or …

Learning From Public Spaces In Historic Cities, Cody Josh Kucharski

Symposium of Student Scholars

Successful public spaces in cities are key for enhancing social cohesion and improving health and safety. Learning from historic cities involves the development of representational and analytical tools aimed at capturing their essence as places of human interaction. The research reports findings of the spatial analysis of twenty Adriatic and Ionian coastal cities, which addresses the question of how the network of public spaces calibrates different degrees of spatial enclosure necessary for creating successful social interactions. Cities in the littoral region include well-preserved historic centers that are renowned for the successful integration of urban squares into the urban fabric. For …

Measuring The Exposure And Vulnerability Of Transit Riders To Cold Temperatures In London, Ontario, Armin Mahboubi

Undergraduate Student Research Internships Conference

Due to the expansion of suburban areas in many cities around the world, accessibility to public transit through walking has become a new challenge for riders. Considering the impacts of climate change in creating more extreme weather, such as extreme cold, heat, or flooding, transit riders may thus be at a higher risk of exposure for various weather-related illnesses (Fraser & Chester, 2016).

Using ArcGIS Pro and ArcMap software, and data collected from City of London’s Open Portal, the United States Geological Survey, Open Mobility Data, and Statistics Canada, the exposure and vulnerability of transit riders to cold temperatures in …

Planning For Micromobilities In Canada: Transportation Policy Review, Nathaniel C. Frisbee Ba, Jason Gilliland Phd, Jinhyung Lee Phd

Undergraduate Student Research Internships Conference

Canadian municipalities face a complex decision on how they tackle the ‘wicked problem’ of climate change over the next decades. One form of sustainable transportation that municipalities could pursue is light electric vehicles (LEVs), commonly referred to as e-bikes and e-scooters or referred to as a Power Assisted-Bicycle by Transportation Canada. Transportation-related policies and plans of Canadian municipalities were evaluated for their consideration of LEVs. Municipalities were selected based on having a university campus within their boundaries, as this is where the highest density of Canadian population resides. The analysis spreads across all 10 provinces in Canada.  There are significant …

Evaluation Of Oregon’S Food Waste Recovery And Reintegration Policy Adoption Through Civic Capacity, Jenna N. Stathopoulos

Student Research Symposium

The US Food System is complex and multi-layered, containing many areas for improvement. My research focuses specifically on the issue area of food waste. On a global and national scale mitigating food waste can seem too large to manage. Containing complexity across multiple sectors and with extended timelines for improvements, it is indeed a wicked problem, a problem which in its complexity is almost impossible to fully distinguish or address with one (or even multiple) solutions. (Rittel, 1973). However, when we look to local, place-based solutions we can develop more realistic and actionable plans. The state of Oregon is equipped …

“Mecca For The Colored People”: Reexamining The Demolition Of Pittsburgh’S Lower Hill District, Avishek Acharya

Undergraduate Research and Scholarship Symposium

The Hill District of Pittsburgh is a neighborhood of national importance, having hosted jazz legends, nationally renowned newspapers, and artists. However, the Hill of today is much smaller than it has ever been; the destruction of the Lower Hill effectively separated the neighborhood from not only another part of the previously collectively one singular neighborhood but separated the neighborhood and its residents from the economic hubs in both down and uptown. The wholesale destruction of the Lower Hill District can be attributed to both the national trend of “urban renewal,” a series of misguided, often explicitly racist attempts to undo …

Among the many collaterals impacts of vehicle electrification is a reduction in funding for government agencies who rely heavily on fuel taxation—over 75B annually—for transportation needs. States and the federal government are actively exploring user-based funding alternatives to pay for the next generation of roads that will be used by the next generation of vehicles.

Community Responses To Food Insecurity During Covid-19: A Case Study In Sheffield, England, Nicole Kennard

Urban Food Systems Symposium

The COVID-19 pandemic gave rise to a group of newly food insecure people and deepened hardship for those already food insecure. The crisis disrupted national food supplies and created challenges to accessing and utilizing the food that was available. As financial struggle deepened for people, and some became unable to shop for food or cook due to isolation requirements and illness, many turned to community organizations to obtain food. In Sheffield, England, small community food organizations soon became the leaders of the city’s emergency food response. One such organization is the Foodhall Project, a community food organization which had previously …

Geographic Study Of Latinx Immigrant-Owned Markets In Cobb County, Georgia, Brittney Brown

Symposium of Student Scholars

Immigrant-owned businesses allow for immigrants to establish themselves in a foreign country and can also provide a sense of community to other immigrants living in the same area. Immigrants tend to settle in areas where there are others of the same nationality and speak the same languages, because it provides immigrants with a social connection. Immigrant-owned businesses can be indicative of an ethnoburb, which is defined as a notable cluster of an ethnic minority population in a suburban context. With a focus on Latinx immigrant-owned markets in Cobb County, Georgia, this study aims to find the connection between Latinx immigrant-owned …

From Displaced To Our Place: Using An Educational Narrative To Build Community In A Displaced Community, Morgan Frederick

Symposium of Student Scholars

Thomasville heights is a displacement neighborhood for people pushed out by Atlanta’s Urban Renewal projects. Thomasville Heights remains a casualty of a system of economic segregation. Under this system of segregation these neighborhoods are left in detrimental states. It is in places like Thomasville Heights where the phrase “place matters” becomes a call to action. A town of 6000 residents and only one elementary school, Thomasville heights is bordered by multiple freight yards, a cemetery, landfills, and Atlanta’s US penitentiary, just a 5-minute walk from that one elementary school. There remains a vast difference between that of low-income urban, and …

Urban Resilience And Impact On Utility Services - Panel Discussion Iii, Noman Ahmed, Laeeq Ahmed, Sadia Dada, Javed Younas

CBER Conference

The government services departments are ill-equipped to provide sufficient services to the people of Karachi. The authorities are solely responsible for lack of provision of services resulting in the city’s dysfunction in the event of natural disasters. The physical existence of service delivery corridors should be notified to the public and a comprehensive plan needs to be put in place to create awareness about the rights of the consumers and utilities service providers. 75% of Karachi today does not experience load-shedding, adding that the illegal encroachment in the city is leading to safety impairment. Currently the eco-system is not conducive …

Metro De Medellín: Urban Infrastructure And Historical Memory In The Creation Of Territorial Belonging And Identity, Phoenix Paz, Paula-Andrea Valencia-Londoño

Peace and Conflict Studies Journal Conference

Medellín and its sister cities in the Valle de Aburrá, Colombia is are renowned for their polarized past, a site of violent encounter between drug cartels, paramilitary groups, urban guerillas, and national forces from the 1970s until today. However, for over a century, it has also been a beacon of hope for thousands of people forcibly displaced by the country’s rural inter intercity violence or hoping to better their lives through participating in the growing industrial sector. In November 1995, just two years after the death of Pablo Escobar and the dissolution of the Medellín Cartel, the Metro of Medellín …

Pig Iron To Wrought Iron: Lake Oswego's Transformation From Iron Smelting To The Privatization Of Oswego Lake, Mathew K. Ragsdale

Young Historians Conference

The paper focuses on the interaction between Oregon's public trust doctrine, city ordinances, and private interests surrounding access to Oswego Lake. Areas of study include the early development of Lake Oswego with its prominence in the Oregon iron industry, and its transition from industrial town to weekend retreat to affluent suburb between the late 1800s and mid 1900s. The Lake Oswego Corporation has claimed power over all aspects of the lake, a notion disputed by Oregon's strong public trust doctrine. The city, whose duty is to all residents, has used the lake as a public asset while restricting access to …

216— Using Rochester’S Family Public Housing In The “Crescent Of Poverty” As A Catalyst For A Solar Initiative, Christopher Miller

GREAT Day Posters

Both the climate crisis and poverty rates in US cities have increased rapidly, with few solutions. This research examines the relative solar potential in public housing developments in Rochester, NY, specifically in the area of concentrated poverty called the “Crescent of Poverty.” Also examined are societal benefits that an inclusive solar/sustainability movement provides for Rochester. Rochester is a mid-sized, diversely populated city with an overall poverty rate >30% and a childhood poverty rate >50% (Murphy, 2018). These alarming rates have contributed to the creation of the “Crescent of Poverty”, where the majority of family public housing developments are located. Solar …

"A State Sponsored System Of Segregation": Examining The Contemporary Impact Of Redlining, Caroline Howard

Showcase of Osprey Advancements in Research and Scholarship (SOARS)

The west side of downtown Jacksonville is home to historically black neighborhoods which for over a century were economically thriving. However, if you were to visit those areas today you would be greeted by vacant lots, abandoned buildings and a large homeless population. In the 1930’s predominantly black neighborhoods of Jacksonville were marked as hazardous areas unfit for loans: a process known as redlining. The Economic Innovation Group’s Distressed Community Index will be analyzed to determine if there is a correlation between redlining and the disproportionate economic hardship of historically black areas to predominantly white areas of Jacksonville. Utilizing GIS …
