Arjen Y. Hoekstra 1967–2019, Davy Vanham, Mesfin Mekonnen, Ashok K. Chapagain

Daugherty Water for Food Global Institute: Faculty Publications

Arjen Hoekstra introduced the water footprint in 20021, building on the concept of virtual water Tony Allan to discuss the role of trade in alleviating water scarcity in the Middle East. He thereby opened a new dimension in the debate around fair and sustainable allocation of freshwater resources. He laid the foundations to show the role of indirect water (that is, water used elsewhere to produce goods we consume) in our daily life beyond our direct use for drinking, cooking or washing. The water footprint is an indicator of direct and indirect water use by a producer or consumer, showing ...

Fires are frequent in boreal forests affecting forest areas. The detection of forest disturbances and the monitoring of forest restoration are critical for forest management. Vegetation phenology information in remote sensing images may interfere with the monitoring of vegetation restoration, but little research has been done on this issue. Remote sensing and the geographic information system (GIS) have emerged as important tools in providing valuable information about vegetation phenology. Based on the MODIS and Landsat time-series images acquired from 2000 to 2018, this study uses the spatio-temporal data fusion method to construct reflectance images of vegetation with a relatively consistent ...


Impacts Of Beef Concentrated Animal Feeding Operations On Environmental Sustainability In The United States And Practices For Improvement, Laura Clark 2020 Virginia Commonwealth University

Impacts Of Beef Concentrated Animal Feeding Operations On Environmental Sustainability In The United States And Practices For Improvement, Laura Clark

VCU Phi Kappa Phi Award Winners

The geographic concentration of beef concentrated animal feeding operations [CAFOs] has changed the landscape of environmental sustainability for agriculture in the United States. As land availability has decreased, operations have struggled to maintain feasible practices to minimize environmental detriment. The United States Environmental Protection Agency [EPA] imposed rules to be followed as a means of mitigation, but the fast-paced rate of change minimizes effectiveness. The overall environmental sustainability of beef CAFOs has shifted from historical rates, leading to a need for reassessment. Part of this reassessment will include stronger environmental practices to be considered for implementation. I explored the role ...

Agricultural and Biosystems Engineering Conference Proceedings and Presentations

Gaseous emissions, a side effect of livestock and poultry production, need to be mitigated to improve sustainability. Emissions of odorous gases like ammonia (NH3) have a detrimental effect on the environment. We are building on previous research to bring advanced oxidation technologies from the lab to the farm. To date, we have shown that ultraviolet A (UV-A) has the potential to mitigate selected odorous gases in the swine production. Much less research on emissions mitigation has been conducted in the poultry production. Thus, the study objective was to investigate whether the UV-A can mitigate NH3 that is a surrogate gas ...

Agricultural and Biosystems Engineering Conference Proceedings and Presentations

Hydrogen sulfide and ammonia are always a concern in the livestock industries, especially when farmers try to clear their manure storage pits. Agitation of manure can cause dangerously high concentrations of harmful agents such as H2S and NH3 to be emitted into the air. Biochar can absorb these gases. We hypothesized that applying biochar on top of manure can create an effective barrier to protect farmers and animals from exposure to NH3 and H2S. In this study, one kind of biochar was tested, highly alkaline, and porous (HAP, pH 9.2) biochar made from ...


Plastics Derived From Derelict Fishing Gear In The Arctic: Looking At Sustainable Fisheries For A Strategy Of Mitigation, Remediation And Prevention In Iceland And Alaska, Natalie S. Armstrong 2020 Pitzer College

Plastics Derived From Derelict Fishing Gear In The Arctic: Looking At Sustainable Fisheries For A Strategy Of Mitigation, Remediation And Prevention In Iceland And Alaska, Natalie S. Armstrong

Pitzer Senior Theses

Marine plastics are not just a problem, they are a silent, sinister epidemic. Marine plastics are the largest economic and ecological threat to our marine ecosystems, particularly marine plastics derived from lost and or discarded fishing gear, which affects sensitive marine communities, the chemical composition of the ocean water, and the physical makeup of the seafloor. With 6.4 million tons of marine debris entering our oceans annually, a third of which is lost fishing gear, it is estimated that, by weight, in 2050 there will be an accumulation of more plastic than fish in the ocean (Heath, 2018; Wilcox ...


Ecowomanism: A Solution To Climate And Social Injustice, Alexis K. Karon 2020 Augustana College, Rock Island Illinois

Ecowomanism: A Solution To Climate And Social Injustice, Alexis K. Karon

Religion: Student Scholarship & Creative Works

The interconnections of climate justice and social inequalities are paired together in a concept named 'Ecowomanism'. Originally inspired by Melanie L. Harris, ecowomanism uses spiritual theologies, experiences, and memories to discuss the post-modern struggles that women of African and indigenous descent face in society, which can then find solutions to such injustices in a reconnection to nature. In this paper, I argue that adopting an environmental paradigm inspired by the spiritual theology of ecowomanism in the United States, which acknowledges the connection between oppression and violence against communities of color to the violence and domination of the environment, a more ...

Distribution Of Human Exposure To Ozone During Commuting Hours In Connecticut Using The Cellular Device Network, Owais Gilani, Simon Urbanek, Michael J. Kane

Faculty Journal Articles

Epidemiologic studies have established associations between various air pollutants and adverse health outcomes for adults and children. Due to high costs of monitoring air pollutant concentrations for subjects enrolled in a study, statisticians predict exposure concentrations from spatial models that are developed using concentrations monitored at a few sites. In the absence of detailed information on when and where subjects move during the study window, researchers typically assume that the subjects spend their entire day at home, school, or work. This assumption can potentially lead to large exposure assignment bias. In this study, we aim to determine the distribution of ...


Gulf Coast Marine Laboratories Past, Present And Future, Donald F. Boesch 2020 University of Maryland Center for Environmental Science

Gulf Coast Marine Laboratories Past, Present And Future, Donald F. Boesch

Gulf and Caribbean Research

I spent my nearly 50—year career in marine science working at marine laboratories, most of that as a chief executive officer. So, it is appropriate that my reflections are about marine laboratories, rather than my own science. After relating my career course, I turn my attention to the history and development of marine laboratories along the U.S. coast of the Gulf of Mexico (GOM). Surprisingly, the region’s first laboratory was actually constructed in 1903 at Cameron, LA, but operated less than a decade before closing. It was not until after World War II that the university—affiliated ...


A Spatially Distributed Investigation Of Stream Water Temperature In A Contemporary Mixed-Land-Use Watershed, Jason P. Horne 2020 West Virginia University

A Spatially Distributed Investigation Of Stream Water Temperature In A Contemporary Mixed-Land-Use Watershed, Jason P. Horne

Graduate Theses, Dissertations, and Problem Reports

Stream water temperature is an important physical variable that influences many biological and abiotic water quality processes. The land-use/land-cover (LULC) types and corresponding variability in stream water temperature (Tw) processes in contemporary mixed-land-use watersheds necessitate research to advance management and policy decisions. Water temperature was analyzed from 21 gauging sites using a nested-scale experimental watershed study design. Results showed that forested land use was significantly negatively correlated (α = 0.05) with mean and maximum Tw. Agricultural land use was significantly positively correlated (α = 0.05) with maximum Tw except during the spring season. Mixed development and Tw were significantly ...

Enhancing Models And Measurements Of Traffic-Related Air Pollutants For Health Studies Using Dispersion Modeling And Bayesian Data Fusion, Stuart A. Batterman, Veronica J. Berrocal, Chad Milando, Owais Gilani, Saravanan Arunachalam, K. Max Zhang

Faculty Journal Articles

Research Report 202 describes a study led by Dr. Stuart Batterman at the University of Michigan, Ann Arbor and colleagues. The investigators evaluated the ability to predict traffic-related air pollution using a variety of methods and models, including a line source air pollution dispersion model and sophisticated spatiotemporal Bayesian data fusion methods. Exposure assessment for traffic-related air pollution is challenging because the pollutants are a complex mixture and vary greatly over space and time. Because extensive direct monitoring is difficult and expensive, a number of modeling approaches have been developed, but each model has its own limitations and errors.

Sealed For Your Protection, Olive Dunham Werby

Senior Projects Spring 2020

In this project, I ruminate on the shiny, shape shifting polymer saturated world we are continuously creating. Oil, plastic, and fossil fuels are all very convenient for turning a profit, for consuming more and more, for the structures in place today. Concurrently, it is becoming increasingly inconvenient for our future generations to avoid extinction.


Exploring The Precursors Of Disinfection Byproducts And Cdom Fluorescence Monitoring, Victoria Choy 2020 Bard College

Exploring The Precursors Of Disinfection Byproducts And Cdom Fluorescence Monitoring, Victoria Choy

Senior Projects Spring 2020

Disinfection byproducts (DBPs) are formed when chlorine, or any other disinfectant, is added to drinking water and reacts to a small fraction of natural organic matter (NOM) present in the water supply. DBPs may be carcinogenic when exposed to for a long term at high concentrations. However, the usage of chlorine or other disinfectants on the water supply must not be compromised. The precursors of DBPs are studied in the Saw Kill by acquiring data from 2017 to 2019 from the Saw Kill Monitoring Program. This includes colored dissolved organic matter (CDOM), chlorophyll a, and turbidity, which are indicative of ...
