Department of Earth and Environmental Studies Faculty Scholarship and Creative Works

This paper addresses urban sustainability challenges amid global urbanization, emphasizing the need for innovative approaches aligned with the Sustainable Development Goals. While traditional tools and linear models offer insights, they fall short in presenting a holistic view of complex urban challenges. System dynamics (SD) models that are often utilized to provide holistic, systematic understanding of a research subject, like the urban system, emerge as valuable tools, but data scarcity and theoretical inadequacy pose challenges. The research reviews relevant papers on recent SD model applications in urban sustainability since 2018, categorizing them based on nine key indicators. Among the reviewed papers, …

Nanoparticles Of Iridium And Other Platinum Group Elements Identified In Chicxulub Asteroid Impact Spherules – Implications For Impact Winter And Profound Climate Change, Vivi Vajda, Susan Nehzati, Gavin Kenny, Hermann D. Bermúdez, Ashley Krüger, Alexander Björling, Adriana Ocampo, Ying Cui, Kajsa G.V. Sigfridsson Clauss

Department of Earth and Environmental Studies Faculty Scholarship and Creative Works

The Chicxulub asteroid that ended the Cretaceous Era ∼66.05 million years ago caused a prolonged time of global darkness – the impact winter – leading to mass extinctions. Elements from the asteroid, including the platinum group elements (PGEs) osmium, iridium and platinum are known from the globally distributed boundary clay but their carrier elements have so far been unknown. We identify, for the first time in detail, the presence of these PGEs within Chicxulub impact spherules and importantly, we identify their carrier elements. We show through synchrotron Nano-XRF how these PGEs occur in nanostructures as un-ordered cube- and/or needle-like crystals …

Evaluating The Ghg Emissions, Land Use, And Water Use Associated With Contemporary Dietary Patterns In The Republic Of Ireland, Daniel Burke, Paul Hynds, Anushree Priyadarshini

Articles

Dietary patterns are intrinsically linked to greenhouse (GHG) emissions, land use, and water use via food production systems. Analysing and comparing contemporary dietary patterns and their environmental impact is critical to identifying which should be promoted to enhance global sustainability. A cross-sectional survey of adult consumption patterns was conducted across Ireland with a representative sample size of 957 respondents. Subsequently, a farm-to-fork life cycle assessment (LCA) was employed via OpenLCA 2.0.4 to assess three primary environmental impacts (global warming, land use, and water use) across the population. Thirteen distinct dietary patterns were analysed: total population, rural, urban, self-reported (omnivore, flexitarian, …

Luminescence Dating Of Hydrothermal Explosions In The Yellowstone Plateau Volcanic Field, Karissa Cordero, Nathan D. Brown, Lauren N. Harrison, Shaul Hurwitz

Earth & Environmental Sciences Datasets - Archive

Hydrothermal explosions are a significant geological hazard in some active volcanic systems; however, the timing and triggering mechanisms of these explosions are poorly constrained. This study applies luminescence dating techniques to hydrothermal explosion deposits in the Yellowstone Plateau volcanic field to constrain explosion chronologies and evaluate potential triggering mechanisms. We tested four luminescence dating techniques: K-feldspar post-infrared infrared stimulated luminescence (pIRIR225), quartz blue light optically stimulated luminescence (BLOSL), quartz blue thermoluminescence (BTL), and quartz red thermoluminescence (RTL). The pIRIR225 and RTL protocols produce consistent age estimates that agree with independent radiocarbon ages and with the timing of the Pinedale deglaciation. …

A Holistic Marine Biosecurity Risk Framework That Is Inclusive Of Social, Cultural, Economic And Ecological Values, Marnie L. Campbell, Chad L. Hewitt

Research outputs 2022 to 2026

Effectively managing non-indigenous marine species risks demands swift, transparent decisions amid limited data and in an environment where conflicting interest across environmental, economic, social, and cultural realms exists. Conventional risk assessment tools often fail to comprehensively evaluate these risks together, leading to stakeholder dissatisfaction, conflicts and poor biosecurity outcomes. To address this, we present a structured 7-step marine biosecurity risk framework. It systematically assesses incursion's ecological, economic, social and cultural impacts, encourages stakeholder engagement and promotes inclusive decision-making. Steps include defining contexts, setting objectives, estimating consequences, determining management options, evaluating trade-offs, implementing decisions, and communicating risks effectively. A simulation using …

Development Of Soil Survey Methods For Urban Areas, Kohinoor Begum

Dissertations, Theses, and Capstone Projects

Urban soils are the foundation of urban ecosystems and play a vital role in long-term urban sustainability and resiliency. Accurate soil surveys of urban areas should be done at higher resolution since extensive human activities often result in urban soil being highly disturbed and spatially variable. Besides heterogeneity, one of the unique and challenging aspects of urban soil is the nature and properties of its organic carbon with a significant percentage of black carbon (a particulate product of incomplete combustion), which is less biologically active. Thus, in order to determine the ability of a soil to support biological activity and …

3bb: Loss And Remembrance In The Anthropocene, Amanda J. Woolsey

Dissertations, Theses, and Capstone Projects

Undisputedly, we are living in a time of tremendous and unprecedented ecological loss. Various forms of life on earth are disappearing at a rate unheard of in human history, with a growing amount of evidence suggesting that we are in a period of mass biodiversity loss and extinction. This extinction event is marked by a series of environmental catastrophes that vary in acceleration, intensity, and impact, such as climate-change driven weather events wiping out an endemic island species, to habitat loss and fragmentation leading to the slow death of a once-common species. One such piece of supporting evidence is Rosenberg …

Microplastic Accumulation In Soils: Unlocking The Mechanism And Biodegradation Pathway, Minh-Ky Nguyen, Md. Refat Jahan Rakib, Myung Hwangbo, Jongsun Kim

School of Earth, Environmental, & Marine Sciences Faculty Publications

Plastic pollution has become a pressing environmental issue, with significant quantities of microplastics (MPs) contaminating terrestrial ecosystems. In agro-environments and soils, the abundance of MPs has been reported to range from 3.7 to 40,800 items per kilogram. Once MPs enter the soil, their accumulation can have several detrimental effects on the soil environment and ecosystems. This review summarizes current research on the biodegradation of MP-contaminated soils. The primary mechanism of MP biodegradation involves enzymatic oxidation and hydrolysis, leading to the formation of functional groups. The interaction between microorganisms and polymers involves various processes, including colonization, biofilm formation, and biodegradation. Microorganisms …

Construction Of Electrically Heated Pavement Using Recycled Waste Rubber Tires, Islam M. Radwan, Mohamed Abdel-Raheem

Civil Engineering Faculty Publications

Accumulated snow on roads presents a dual risk of accidents and financial losses. Conventional de-icing methods, which rely on chemicals, salt, and heavy machinery, are unsustainable and detrimental to both the environment and infrastructure. Furthermore, they demand significant labor and pose hazards in densely populated areas. In response, heated pavement systems such as hydronic and electrically conductive concrete (ECON) have gained traction for mitigating snow accumulation on roads. However, the use of carbon fiber and carbon black in ECON raises costs and depletes valuable resources. This research introduces an inventive and sustainable approach to address snow accumulation on rigid pavements …

Is Carbon Risk Priced In The Cross Section Of Corporate Bond Returns?, Tinghua Duan, Frank Weikai Li, Quan Wen

Research Collection Lee Kong Chian School Of Business

This article examines the pricing of a firm’s carbon risk in the corporate bond market. Contrary to the “carbon risk premium” hypothesis, bonds of more carbon-intensive firms earn significantly lower returns. This effect cannot be explained by a comprehensive list of bond characteristics and exposure to known risk factors. Investigating sources of the low carbon alpha, we find the underperformance of bonds issued by carbon-intensive firms cannot be fully explained by divestment from institutional investors. Instead, our evidence is most consistent with investor underreaction to the predictability of carbon intensity for firm cash-flow news, creditworthiness, and environmental incidents.
