Megaloads And Mobilization: The Rural People Of Idaho Stand Against Big Oil, Corrie Grosse Dec 2017

Megaloads And Mobilization: The Rural People Of Idaho Stand Against Big Oil, Corrie Grosse

Environmental Studies Faculty Publications

From 2011 to 2014 fossil fuel corporations trucked tar sands processing machinery along rural Idaho highways. The machinery was bound for the world's largest deposits of tar or oil sands, a heavy crude oil substance called bitumen, located in the western Canadian province of Alberta. These loads of machinery, what became known as megaloads, encountered much resistance. Throughout Idaho and the surrounding region, a network organized opposition. Neighbors, grassroots organizations, nonprofits, and the Nez Perce and other tribes all collaborated. They held information sessions, protested, waged legal battles, monitored the loads, and blockaded highways. What oil companies hoped would be …


"The Devil Is In The Details:" Inland Northwest Stakeholders’ Views On Three Forest-Based Bioenergy Scenarios, Soren Newman, Darin Saul, Robert Keefe, Ryan Jacobson, Tamara Laninga, Jillian Moroney Dec 2017

"The Devil Is In The Details:" Inland Northwest Stakeholders’ Views On Three Forest-Based Bioenergy Scenarios, Soren Newman, Darin Saul, Robert Keefe, Ryan Jacobson, Tamara Laninga, Jillian Moroney

University Author Recognition Bibliography: 2017

Public and private initiatives are actively exploring a range of forest-based bioenergy development options in the Inland Northwest of the United States. These efforts are motivated in part by the potential to generate renewable energy while creating a market for forest residues that would facilitate hazardous fuels reduction and provide economic opportunities. Understanding stakeholders’ perspectives is critical to the feasibility and long-term viability of bioenergy projects. This study presents stakeholder perspectives on forest-based bioenergy development strategies for communities in the forested areas of Idaho, western Montana, eastern Washington, and eastern Oregon. We developed three scenarios based on bioenergy initiatives currently …


Eliminate The Carbon Externality, Connor Mcfayden Dec 2017

Eliminate The Carbon Externality, Connor Mcfayden

Op-Eds from ENSC230 Energy and the Environment: Economics and Policies

Before we do anything else, let’s establish two things: the global climate is changing at an alarming rate and the primary cause is human CO2 emissions. There is a worldwide scientific consensus on this fact. Even our own government, despite a remarkably vocal minority, has confirmed this. A report released this year by 13 government agencies identifies humans as the primary cause of global climate change and links this phenomenon to rising sea levels, increased incidence of droughts and floods, and the intensification of large storms. These events are the result of the carbon externality, the social costs of emissions …


A Forgotten Resource: Thorium, Daniel Rico Dec 2017

A Forgotten Resource: Thorium, Daniel Rico

Op-Eds from ENSC230 Energy and the Environment: Economics and Policies

The year is 1945, the morning of August 6th, 8:16am to be exact. The United States just dropped the world’s first militarized atomic weapon on Hiroshima, Japan. With this singular act the world virtually witnessed the end of its second world war, the birth of warfare like never before, and the foreseeable death of nuclear power. With this act an aura of negativity and destruction accompanied the word nuclear that it would likely never be rid of despite untapped high grade energy potential that can outweigh its military application. The bomb dropped on Hiroshima was composed of 64 …


Lithium-Ion Batteries: It’S Not About The Lithium., Jace Kranau Dec 2017

Lithium-Ion Batteries: It’S Not About The Lithium., Jace Kranau

Op-Eds from ENSC230 Energy and the Environment: Economics and Policies

Malnourished children and tired men chip away with ancient tools at Cobalt-containing rock for you to have the next best electronic device. The impoverished, artisanal workers of the Democratic Republic of Congo (DRC) supply up to 25 percent of global Cobalt according to The Washington Post. The battery manufacturers don’t care. Their dominant thought is profit.

Artisanal workers are paid between two and three U.S. dollars a day. “We are suffering. And our suffering is for what?”, 29-year-old digger, Nathan Muyamba, told The Post.

The batteries in phones, laptops and for some, their cars, contain Lithium, Cobalt, Nickel …


Gmo Regulations Are Killing Biofuels, Megan Franklin Dec 2017

Gmo Regulations Are Killing Biofuels, Megan Franklin

Op-Eds from ENSC230 Energy and the Environment: Economics and Policies

Progress in creating profitable biofuels is being slowed down by strict regulations on genetically engineered (GE) crops (aka GMOs). Setbacks that biofuels face can be addressed with genetic engineering. However, public pushback and regulations make it extremely difficult to implement solutions. We should have more lenient regulations on GE crops so that we can speed up the progress of improving biofuels.

A genetically engineered crop is one that has DNA from a different species inserted into its own DNA. As a result from GE crop benefits, CO2 emissions were reduced by 26.7 billion kg in 2012, and poverty was alleviated …

Palm Oil: The Hidden Costs

Lurking behind your soaps, cosmetics, pantry groceries, and household cleaning supplies is a product killing endangered species in Southeast Asia. This same product is destroying the survival mechanisms for local communities in Southeast Asia while pumping large amounts of greenhouse gas emissions into the atmosphere. To keep its identity hidden, it uses over twenty different names on ingredient labels. What is this product? Palm oil. Palm oil is the most widely used vegetable oil in the world and increased demand for palm oil in our …


Cardboard Ban Is An Investment Opportunity, John Schwaninger Dec 2017

Cardboard Ban Is An Investment Opportunity, John Schwaninger

Op-Eds from ENSC230 Energy and the Environment: Economics and Policies

Lincoln’s cardboard ban was a hot topic in 2016, but 2017 has shifted focus to the city’s recycling education contract. Gone is discussion of Mayor Chris Beutler’s failed, revived and ultimately victorious struggle to reform Lincoln’s recycling program. In its place, an air of financial discomfort stagnates over the city’s already troubled budget.

The cardboard ban will take effect April 2018. The recycling education program was drafted in part to support the ban by educating households about recycling drop-off locations and sorting requirements. However, the recycling education contract’s $850,000 cost raised eyebrows, undermining Beutler’s earlier effort.

The recycling education contract’s …


Crop Productivity In The Ag Belt On Borrowed Time, Logan Winters Dec 2017

Crop Productivity In The Ag Belt On Borrowed Time, Logan Winters

Op-Eds from ENSC230 Energy and the Environment: Economics and Policies

Most people by now have heard the terms “climate change” and global warming. Many acknowledge that it’s a problem, but they may not know how it can impact them directly. This is especially true for those living in the middle of the country, because most of the media attention goes to the coastal impacts of climate change. While putting adequate focus on the coastal impacts is a good start, since the most widespread and severe impacts will be coastal, but there needs to be more talk and discussion about the future impacts over the middle of the country. One big …


How Innovative Companies Gain From A Cap And Trade Agreement, Lucian Montgomery Dec 2017

How Innovative Companies Gain From A Cap And Trade Agreement, Lucian Montgomery

Op-Eds from ENSC230 Energy and the Environment: Economics and Policies

The purpose of both a cap and trade agreement and a carbon tax is to reduce emissions by setting a price on carbon. However, that is where the similarities end.

A cap and trade agreement gives a certain amount of allowances to each company that adds up to an emissions cap, allows companies to trade them. Companies only pay for carbon emissions if they produce more than the amount of allowances they are given, either by paying penalties to the government, or by buying more allowances from other companies. This creates a market for allowances, and based on demand, sets …


Building Our Way To A Better Future, Brad Shaner Dec 2017

Building Our Way To A Better Future, Brad Shaner

Op-Eds from ENSC230 Energy and the Environment: Economics and Policies

The potential demolishing of the Clean Power Plan by the federal government in early October is looking like a losing fight in our war against carbon emissions at one of the biggest sources of these emissions. But we can continue to fight in this war and make an even bigger impact by focusing our efforts on the most ordinary and consistent thing in our modern lives; the buildings we live and work in. Some would say that high efficiency or green buildings are a commodity that only the wealthy individuals or businesses can achieve, but this doesn’t have to be …


The Fossil Fuel Energy Industry Vs. The Endangered Species Act, Cody Willnerd Dec 2017

The Fossil Fuel Energy Industry Vs. The Endangered Species Act, Cody Willnerd

Op-Eds from ENSC230 Energy and the Environment: Economics and Policies

It was several weeks ago that the Congressional Republicans made a push to reform the landmark Endangered Species Act to make it more friendly to landowners and fossil fuel industries. They would do this by releasing species earlier on the ESA list than before and instead focus on species that are in the greatest of need of attention. The reform would also have agencies focus on the economic costs to deny listings of species, require the agency to listen towards states concerns, and limit payouts for attorney fees in ESA litigations. This would be incredibly damaging to many species that …


Energy Star Tax Holiday Simply Advertising Gimmick, Lauren Klaasmeyer Dec 2017

Energy Star Tax Holiday Simply Advertising Gimmick, Lauren Klaasmeyer

Op-Eds from ENSC230 Energy and the Environment: Economics and Policies

In January of this year, Senator Harr introduced Legislative Bill 325. From 12:01 A.M. on the first Friday of October through midnight of the first Sunday, all Energy Star products less than $1500 will be exempt from sales and use taxes. The special interest group, Nebraska Retail Federation, proposed the idea to Senator Harr. There was no move to advance the bill last session, so it could be brought back up this coming session or amended to another bill. When speaking with people at the capitol, it was said that the main reason it was not advanced was because of …


The Tax That Will Actually Do Something Is Not In The Current Bill, Steven Kirchner Dec 2017

The Tax That Will Actually Do Something Is Not In The Current Bill, Steven Kirchner

Op-Eds from ENSC230 Energy and the Environment: Economics and Policies

If we are going to be talking about tax reform, we should be talking about solutions that will actually solve a problem. The combustion of fossil fuels has much more than environmental implications. Burning fossil fuels is a blatant catastrophe for our entire economic system. The current American energy market is entirely reliant on fossil fuels (coal, oil, and natural gas). Negative externalities have flooded the American economic system because of the combustion of fossil fuels. A negative externality is a cost that indirectly affects someone outside of the economic transaction. That third party entity must bear the burden of …


Recent Increase In Deadly Storms, Westin Longacre Dec 2017

Recent Increase In Deadly Storms, Westin Longacre

Op-Eds from ENSC230 Energy and the Environment: Economics and Policies

These last few years have hit us with some devastating storms that continue to wreck havoc on our earth. We have been hit with multiple storms that are so strong that they are predicted to happen every 50 years, so is God punishing us? Or do we have something to do with this? This issue should be a huge concern to us because who knows how many more of these devastating storms we can handle. When looking at why these tragic storms are happening more frequently the main factor that is leading to these events is the increase in atmospheric …


Wind Is Nebraska’S Future, With Or Without The Clean Power Plan, Megan Pamperin Dec 2017

Wind Is Nebraska’S Future, With Or Without The Clean Power Plan, Megan Pamperin

Op-Eds from ENSC230 Energy and the Environment: Economics and Policies

The Clean Power Plan was issued in October 2015. President Trump called for a review of the plan this March and on October 16th, 2017 the EPA released a proposal to repeal it. The Clean Power Plan would have reduced Nebraska’s state emissions to 22,250,000 tons of carbon dioxide by 2024, down by about 5 million tons compared to 2012 emissions.1 The new projection for 2020 without the plan is 34 million tons of CO2 emitted.

Coal and other fossil fuel energy sources are the main culprits of these carbon emissions, and here in Nebraska coal …


Anaerobic Digestion In Nebraska, Anthony Leapley Dec 2017

Anaerobic Digestion In Nebraska, Anthony Leapley

Op-Eds from ENSC230 Energy and the Environment: Economics and Policies

Climate change is a global crisis that can be fought by all locally. Nebraska is my home, and it’s one of nine states in the U.S. in which cows outnumber humans. Statistically, there are three cows for every person (1,868,516 humans to 6,150,000 cows). While we have fewer humans than cows, it’s not hard to understand that we rank very low in CO2 emissions when ranking all states in the country. However, our emission of the more potent greenhouse gas CH4, or methane, is significantly higher. Methane is released by cows via gas and manure, and it’s causing serious implications …


The Application And Usefulness Of Economic Analyses For Water Quality Management In Coastal Areas, Sheri L. Jewhurst, Kate K. Mulvaney, Marisa J. Mazzotta Dec 2017

The Application And Usefulness Of Economic Analyses For Water Quality Management In Coastal Areas, Sheri L. Jewhurst, Kate K. Mulvaney, Marisa J. Mazzotta

Journal of Ocean and Coastal Economics

Economic studies are increasingly sought as tools to contribute to water quality management in estuaries and coastal communities, yet little is known about how the results from existing studies have been received and utilized by the organizations who solicited them. We interviewed managers from eight organizations who solicited economic studies over the past 15 years to understand how useful the studies were to their organizations and what economic research would be most helpful for their management needs. In terms of utility for coastal managers, there are a number of limitations in the studies. These include lack of site-specific data, the …


Recycling Clean Energy, Amanda Vaughn Dec 2017

Recycling Clean Energy, Amanda Vaughn

Op-Eds from ENSC230 Energy and the Environment: Economics and Policies

Nuclear energy is one of the cleanest sources of energy available. It does not produce carbon dioxide as the beta decay of Uranium is an exothermic spontaneous process that produces helium. Unfortunately, nuclear waste storage is a large problem in the United States, the cost of maintaining the waste storage facilities alone is 46.7 billion dollars. There is the constant threat of leaks and contaminated water leaking into drinking supplies. Then there is the danger of the current geological storage tanks lasting longer than humanity and spoiling the future environment as current nuclear waste takes millions of years to decompose …


Use Of An Alternative Natural Weed Suppressant: Effects Of Parboiled Rice Hull Mulch On The Growth Of Container Weeds, Amy R. Fields-Taylor, Vanessa Slinger-Friedman Dec 2017

Use Of An Alternative Natural Weed Suppressant: Effects Of Parboiled Rice Hull Mulch On The Growth Of Container Weeds, Amy R. Fields-Taylor, Vanessa Slinger-Friedman

The Kennesaw Journal of Undergraduate Research

The Chattahoochee Nature Center (CNC) is one of the leading educational centers in Georgia about the ecology of the Chattahoochee River. Due to lack of man power, keeping down the weeds in the CNC plant nursery is one of those tasks that often gets left undone. The nursery becomes overgrown with invasive weed species. Understandably, they must sometimes resort to the use of herbicides, such as Roundup®, to keep the hundreds of native and endangered species of plants housed at CNC from being choked out by invasive weeds. This study tests the ability to suppress weed growth by use of …


Remote Sensing Of Forests Using Discrete Return Airborne Lidar, Hamid Hamraz, Marco A. Contreras Dec 2017

Remote Sensing Of Forests Using Discrete Return Airborne Lidar, Hamid Hamraz, Marco A. Contreras

Forestry and Natural Resources Faculty Publications

Airborne discrete return light detection and ranging (LiDAR) point clouds covering forested areas can be processed to segment individual trees and retrieve their morphological attributes. Segmenting individual trees in natural deciduous forests, however, remained a challenge because of the complex and multi-layered canopy. In this chapter, we present (i) a robust segmentation method that avoids a priori assumptions about the canopy structure, (ii) a vertical canopy stratification procedure that improves segmentation of understory trees, (iii) an occlusion model for estimating the point density of each canopy stratum, and (iv) a distributed computing approach for efficient processing at the forest level. …


An Application Of M-Matrices To Preserve Bounded Positive Solutions To The Evolution Equations Of Biofilm Models, Richard S. Landry Jr. Dec 2017

An Application Of M-Matrices To Preserve Bounded Positive Solutions To The Evolution Equations Of Biofilm Models, Richard S. Landry Jr.

University of New Orleans Theses and Dissertations

In this work, we design a linear, two step implicit finite difference method to approximate the solutions of a biological system that describes the interaction between a microbial colony and a surrounding substrate. Three separate models are analyzed, all of which can be described as systems of partial differential equations (PDE)s with nonlinear diffusion and reaction, where the biological colony grows and decays based on the substrate bioavailability. The systems under investigation are all complex models describing the dynamics of biological films. In view of the difficulties to calculate analytical solutions of the models, we design here a numerical technique …


Fossil Fuel Subsidies In America, Jackson Cutsor Dec 2017

Fossil Fuel Subsidies In America, Jackson Cutsor

Op-Eds from ENSC230 Energy and the Environment: Economics and Policies

Two of the most controversial topics in American politics today are climate change and the federal budget. Subsidies for energy generation fit into both categories.

Subsidies given to the energy industry artificially decrease the price of energy and electricity. Low energy prices help stimulate the market, however, the negative externalities like the social cost of carbon and political corruption are not taken into consideration.

Subsidies can come in many forms including: failure to impose external costs, tax breaks, and low interest loans. Even without imposing the social cost of carbon a removal of fossil fuel energy subsidies can have a …


Automated Species Classification Methods For Passive Acoustic Monitoring Of Beaked Whales, John Lebien Dec 2017

Automated Species Classification Methods For Passive Acoustic Monitoring Of Beaked Whales, John Lebien

University of New Orleans Theses and Dissertations

The Littoral Acoustic Demonstration Center has collected passive acoustic monitoring data in the northern Gulf of Mexico since 2001. Recordings were made in 2007 near the Deepwater Horizon oil spill that provide a baseline for an extensive study of regional marine mammal populations in response to the disaster. Animal density estimates can be derived from detections of echolocation signals in the acoustic data. Beaked whales are of particular interest as they remain one of the least understood groups of marine mammals, and relatively few abundance estimates exist. Efficient methods for classifying detected echolocation transients are essential for mining long-term passive …

Assessment Of Vegetation Response To Wildfire At Bandelier National Monument, New Mexico: Case Study Of The Las Conchas Fire, Gladys Valentin-Gonzalez

Geography ETDs

In the past couple of decades, there has been an increase in the occurrence of wildfire events in the United States. The U.S. Forest Service estimates that over 73,000 wildfires on average occur annually in the U.S., burning about 7.3 million acres of land. Bandelier National Monument, in northern New Mexico, has been affected by several wildfires in the past 40 years, one of the most recent being the Las Conchas Fire in 2011, which burned over 60,700 hectaresin Bandelier National Monument and Valles Caldera National Preserve. This research explores a remote-sensing based assessment of vegetation response to and recovery …

The Blurred Line Between Photic And Aphotic Environments: A Large Mexican Cave With Almost No Dark Zone, Luis M. Mejía-Ortíz, Tanja Pipan, David C. Culver, Peter Sprouse

International Journal of Speleology

Sistema Muévelo Rico is a 1.2 km long cave in Quintana Roo, less than 2 km from the Caribbean Sea. We measured illuminance to a level of 0.1 lux, organic matter (weight loss on ignition), temperature, and relative humidity. The last two were measured at hourly intervals for nearly one year. Approximately one-third of the cave has illuminance values greater than 0.01 lux, and most of the rest of the cave has light as well. Temperature and relative humidity were relatively constant, but they showed a daily cycle at all stations, albeit with different strengths. Organic matter averaged 8%, intermediate …


Testing The Underlying Chemical Principles Of The Biotic Ligand Model (Blm) To Marine Copper Systems: Measuring Copper Speciation Using Fluorescence Quenching, Tara N. Tait, James C. Mcgeer, Scott Smith Dec 2017

Testing The Underlying Chemical Principles Of The Biotic Ligand Model (Blm) To Marine Copper Systems: Measuring Copper Speciation Using Fluorescence Quenching, Tara N. Tait, James C. Mcgeer, Scott Smith

Chemistry Faculty Publications

Speciation of copper in marine systems strongly influences the ability of copper to cause toxicity. Natural organic matter (NOM) contains many binding sites which provides a protective effect on copper toxicity. The purpose of this study was to characterize copper binding with NOM using fluorescence quenching techniques. Fluorescence quenching of NOM with copper was performed on nine sea water samples. The resulting stability con- stants and binding capacities were consistent with literature values of marine NOM, show- ing strong binding with log K values from 7.64 to 10.2 and binding capacities ranging from 15 to 3110 nmole mg C −1 …


A Little Known Trade Deal Could Soon Derail America's Booming Solar Industry, Sam Donnenberg Dec 2017

A Little Known Trade Deal Could Soon Derail America's Booming Solar Industry, Sam Donnenberg

Capstones

A trade deal has been winding its way through hearings at the International Trade Commission for months that could have major consequences for America's solar energy industry. Two solar energy companies are requesting that tariffs be applied to Chinese solar product imports. But industry analysts say this will cause the price of solar to rise and harm the industry during a period of unprecedented growth. The petition has only one stop left on its way to approval: The desk of President Trump.

Predicted Suitable Habitat Declines For Midwestern United States Amphibians Under Future Climate And Land-Use Change Scenarios, Brock Struecker, Joseph Milanovich Dec 2017

Predicted Suitable Habitat Declines For Midwestern United States Amphibians Under Future Climate And Land-Use Change Scenarios, Brock Struecker, Joseph Milanovich

Biology: Faculty Publications and Other Works

With current declines of vertebrate taxa meeting or exceeding those of historic mass extinction events, there is a growing need to investigate the main drivers of losses. Two of the main drivers of declines are global climate and land-use changes, both affecting multiple groups of taxa. Amphibians are at great risk from these two drivers of change and investigations into the impact of future change could assist with the formation of conservation plans to mitigate losses. Forecasting changes in suitable habitat with ecological niche modeling serves as a useful tool to begin to understand how species may respond to anthropogenic …
