Sustainability Seminar Series

Partnerships are instrumental to improving water quality, especially difficult challenges like addressing non-point source pollution. Hear how over a thirty year timespan local residents worked to improve water quality, first through protecting the Musconetcong River as a National Wild and Scenic River, and then using that status to work collaboratively with federal and state agencies, non-governmental organizations, and local land owners to reduce pollution from farms and remove abandoned dams.


Compound Extreme Events, Radley Horton May 2021

Compound Extreme Events, Radley Horton

Sustainability Seminar Series

There is a growing realization among scientists and decision makers that extreme events should not be considered in isolation. Compound events of three types will be described: 1) multivariate (e.g. heat plus humidity), 2) sequential (e.g. a heat wave after a tropical cyclone), and 3) concurrent (e.g. simultaneous temperature extremes in multiple regions). Research results will be presented for these compound extremes. More research is needed on correlations and physical mechanisms that can link seemingly independent extreme events. This research is especially urgent now, since climate change may shift the correlation structures of extreme events, and because compound extreme events …

These new requirements are due to social distancing requirements of the pandemic and in light of recent advances in psychology and neuroscience that help us understand better how people experience urban space. Professor Hollander will discuss some of the key findings from his forthcoming book on these topics, co-edited with Ann Sussman: Urban Experience and Design: Contemporary Perspectives on Improving the Public Realm (Routledge, 2021).


The Varying Effects Of Accessing High-Speed Rail System On China’S County Development: A Geographically Weighted Panel Regression Analysis, Danlin Yu Apr 2021

The Varying Effects Of Accessing High-Speed Rail System On China’S County Development: A Geographically Weighted Panel Regression Analysis, Danlin Yu

Sustainability Seminar Series

The construction of high-speed rail in China was initiated to answer increasing demand for fast and convenient transportation systems connecting large economic centers. It is commonly understood that access to HSR will have significant impact on economic development. It is, however, also quite possible that the benefits to economic development brought by HSR will have a diminishing marginal effect. With data of HSR stations distribution and a set of panel data of socioeconomic information at county-level from 2008 – 2015 in China, this study applies advanced spatiotemporal data analysis techniques to investigate the impact of HSR. Our results suggest that …


Elemental Hyper-Accumulation In Mushrooms With A Focus On Arsenic, Walter Goessler Mar 2021

Elemental Hyper-Accumulation In Mushrooms With A Focus On Arsenic, Walter Goessler

Sustainability Seminar Series

Mushrooms play an important role in the biogeochemical cycling of trace elements. They do neither belong to plants nor to animals but form their own kingdom. Some mushrooms live in symbiosis with plants or as parasites on other living organisms. Mushrooms are abundant worldwide. Although omnipresent, they only become noticeable when fruiting bodies are produced. Mushrooms are becoming a more important part of our diet and are used in various aspects of our life. They are used for antibiotics production, in the food industry(wine, cheese...) but also as biological pesticides. New applications cover plastics degradation and use as a leather …


Seeking Sustainability For Computing, Stefan A. Robila Mar 2021

Seeking Sustainability For Computing, Stefan A. Robila

Sustainability Seminar Series

The talk will provide two perspectives on how sustainability is considered in computing. First, the impact computing has on energy consumption and on the environment will be discussed through the prism of past and prior research projects. Computing currently drives advances in all areas of science and engineering, generates efficiencies in industries, and dominates the creation and delivery of entertainment. Computing is also a significant consumer of energy accounting for 3% of the global usage. Data centers account of a third of this consumption, yet also provide a case where efficiencies in system design have limited the energy use increase …

What Can History Tell Us About The Future? Using Recent Observations And Paleoclimate Proxies To Constrain Equilibrium Climate Sensitivity, Kate Marvel Mar 2021

What Can History Tell Us About The Future? Using Recent Observations And Paleoclimate Proxies To Constrain Equilibrium Climate Sensitivity, Kate Marvel

Sustainability Seminar Series

Despite improvements in computing power, climate modeling, and basic theoretical understanding, the Earth’s physical response to a doubling of atmospheric carbon dioxide remains uncertain. Can observations be useful in constraining this theoretical quantity? We have high-­‐quality information on recent trends: greenhouse gas concentrations have increased since the industrial revolution, and the planet has warmed in response. But I will argue that this recent history provides only weak constraints on the eventual climate sensitivity: observations of a transient climate are poor predictors of a future equilibrium state. Reconstructions of past equilibria both colder (the Last Glacial Maximum) and warmer (the mid-­‐Pliocene) …

Our time in the Galapagos, while short, spanned centuries of scientific thought and millions of years of geologic history. The …


Climate Change And Ecosystem Transformation: Plant Wax Evidence From Indian Ocean Drilling, Sarah Feakins Nov 2020

Climate Change And Ecosystem Transformation: Plant Wax Evidence From Indian Ocean Drilling, Sarah Feakins

Sustainability Seminar Series

Plants – from lush rainforests to desert shrublands – map climatic differences on the landscape. The waxy molecules coating plant leaves are some of the most resilient biochemicals made by plants and they contribute to the sedimentary legacy of past environment, archived in deep sea sediments. The International Ocean Discovery Program has recently drilled the two largest submarine fans in the world, the Bengal Fan (Expedition 354) and Indus Fan (Expedition 355). These megafans yield thick deposits of dominantly terrestrial organic matter derived from the GangesBrahmaputra and Indus River systems respectively. In addition, legacy cores from the Gulf of Aden …


Modeling Biotic & Abiotic Drivers Affecting Biogeomorphic Coastal Foredunes, Bianca Charbonneau Nov 2020

Modeling Biotic & Abiotic Drivers Affecting Biogeomorphic Coastal Foredunes, Bianca Charbonneau

Sustainability Seminar Series

Coastal dunes are exceptionally dynamic terrestrial habitats that will only grow increasingly vulnerable with climate change. A structured approach to protect and restore these and other coastal biogeomorphic interface habitats is needed to maintain their invaluable ecosystem services. Vegetation in these habitats acts as ecosystem engineers such that, to achieve this, one must understand and accurately forecast vegetation dynamics at the nexus of shifting abiotic conditions and drivers of change. We developed a process-based model for coastal dune vegetation ecology, specifically, growth, density, and colonization as it affects and is affected by shifting habitat topography and storm event impact. The …


Declining Co2 Price Paths, Gernot Wagner Nov 2020

Declining Co2 Price Paths, Gernot Wagner

Sustainability Seminar Series

Pricing greenhouse-gas (GHG) emissions involves making trade-offs between consumption today and unknown damages in the (distant) future. While decision making under risk and uncertainty is the forte of financial economics, important insights from pricing financial assets do not typically inform standard climate–economy models. Here, we introduce EZ-Climate, a simple recursive dynamic asset pricing model that allows for a calibration of the carbon dioxide (CO2) price path based on probabilistic assumptions around climate damages. Atmospheric CO2 is the “asset” with a negative expected return. The economic model focuses on society’s willingness to substitute consumption across time and across uncertain states of …

Improved Sustainability Of Bridges Through Better Diagnostics And Deeper Understanding Of Deterioration Processes, Nenad Gucunski Oct 2020

Improved Sustainability Of Bridges Through Better Diagnostics And Deeper Understanding Of Deterioration Processes, Nenad Gucunski

Sustainability Seminar Series

Effective and economic management of bridges depends on an accurate assessment of their current condition, and, in turn, prediction of their future performance. Deterioration processes in reinforced concrete, since they are a result of multiple inputs and actions, are inherently complex. To fully and accurately characterize various types of deterioration and gauge its severity, it requires using multiple nondestructive evaluation (NDE) tools in concert with other technologies. Among all the components, reinforced concrete decks deteriorate fastest, primarily due to their direct exposure to traffic and environmental loading, and maintenance actions. Therefore, the most significant advancements in NDE technologies’ efficacy for …


Creating Evidence For Resilience: A Case Of Monsoon Floods Affected Communities In South Asia, Alark Saxena Oct 2020

Creating Evidence For Resilience: A Case Of Monsoon Floods Affected Communities In South Asia, Alark Saxena

Sustainability Seminar Series

The concept of resilience has been rapidly accepted across multiple disciplines and applied work, but operationalizing resilience poses several methodological challenges. Taking the case of two monsoon flood affected transboundary communities situated in the Gangetic plains of South Asia, we provide a framework and methodology to create evidence and evaluate resilience. We present and test two propositions focusing on the variation in wellbeing and the coping capacity that need to be simultaneously satisfied for increased resilience. The two propositions and the methodology are robust to a wide range of shocks and social-ecological systems.


What Cities Can Learn From Trees: Lessons In Urban Ecomimicry, Nathan Phillips Oct 2020

What Cities Can Learn From Trees: Lessons In Urban Ecomimicry, Nathan Phillips

Sustainability Seminar Series

Tree physiologists use a vernacular that translates amazingly well as a lens for understanding the structure, function, and sustainability of cities. Concepts of tree architecture such as efficiency, safety, vulnerability and their tradeoffs find parallels in our urban water, energy and food networks. In this talk I will compare and contrast the world of trees with that of cities and explore how urban planners and policymakers can learn from trees how to build more resilient and sustainable cities.


Taking The Fingerprints Of Sea Level Changes, Jerry Mitrovica Oct 2020

Taking The Fingerprints Of Sea Level Changes, Jerry Mitrovica

Sustainability Seminar Series

The concept of eustasy, that is, the assumption that ice mass changes are accompanied by a globally uniform change in sea level, has -- until relatively recently -- been pervasive in the analysis of paleo and modern sea level records, and has stymied progress in both fields. I will demonstrate, using examples ranging from the last tens of millions of years to the modern world, that a variety of geophysical processes drive sea level changes with significant geographic variability. Modeling of these processes has improved estimates of global mean sea level change, but it has also motivated recent efforts to …

Project Icebreaker: Offshore Wind Project In Lake Erie, Xiangwu (David) Zeng

Sustainability Seminar Series

Wind energy is one of the most promising renewable energy resources. The Great Lakes region in the US has huge potential for offshore wind energy development. However, ice loading in winter brings a unique challenge to the foundations for wind turbines. Model tests and numerical simulation have been conducted to investigate different types of foundations and techniques to reduce the ice loading. The ultimate goal is to design a safe and economical foundation for future large-scale wind farms in the Great Lakes.


Contrasting Storm Surge Barriers And Nature-Based Flood Mitigation For Port-Estuaries, Philip Orton May 2020

Contrasting Storm Surge Barriers And Nature-Based Flood Mitigation For Port-Estuaries, Philip Orton

Sustainability Seminar Series

Deepwater port-estuaries have virtually no accepted and effective nature-based solution for sea level rise, because there is typically too little space for wetlands and deep shipping channels provide relatively friction-free pathways for floodwaters to reach neighborhoods. The Corps of Engineers is evaluating flood risk reduction strategies for the Port of New York and New Jersey and its estuarine waterways, with initial results pointing to gated storm surge barriers as the optimal solution. Jamaica Bay is one relatively unused port sub-estuary where a surge barrier is proposed, and I will demonstrate with computational modeling how a gradual “sedimentary restoration” over several …
