A Life Cycle Analysis Of Land Use In Us Pork Production, Greg Thoma, Marty Matlock, Ben Putman, Jasmina Burek

Food Systems

The goal of this study was to analyze land use in the production of US pork using Life Cycle Assessment (LCA). LCA is a comprehensive methodology for quantitatively analyzing potential environmental impacts associated with complex systems. Identification of processes contributing to high environmental impacts often highlights opportunities for gains in efficiency, which can increase the profitability and sustainability of US pork. The environmental impact category analyzed in this assessment was land use. After reviewing existing information regarding land use in agriculture and livestock production, analysis for US pork production was performed at two scales: cradle-to-grave and cradle-to-farm gate. The cradle-to-grave …

Quantifying The Adaptive Cycle, David G. Angeler, Craig R. Allen, Ahjond S. Garmestani, Lance H. Gunderson, Olle Hjerne, Monika Winder

Nebraska Cooperative Fish and Wildlife Research Unit: Staff Publications

The adaptive cycle was proposed as a conceptual model to portray patterns of change in complex systems. Despite the model having potential for elucidating change across systems, it has been used mainly as a metaphor, describing system dynamics qualitatively. We use a quantitative approach for testing premises (reorganisation, conservatism, adaptation) in the adaptive cycle, using Baltic Sea phytoplankton communities as an example of such complex system dynamics. Phytoplankton organizes in recurring spring and summer blooms, a well-established paradigm in planktology and succession theory, with characteristic temporal trajectories during blooms that may be consistent with adaptive cycle phases. We used long-term …

The Role Of The State, Multinational Oil Companies, International Law & The International Community: Intersection Of Human Rights & Environmental Degradation Climate Change In The 21st Century Caused By Traditional Extractive Practices, The Amazon Rainforest, Indigenous People And Universal Jurisdiction To Resolve The Accountability Issue, Marcela Cabrera Luna

Master's Theses

Local, national and international conventions that protect indigenous sovereignty and their territories, where many of the resources are extracted from by multinational corporations (MNCs) particularly oil, the number one commodity of the world and cause of climate change, continue to be jeopardized because of the lack of a clear international legal framework that can protect them and potentially hold multinationals accountable for their actions. These practices are causing not only environmental issues to the indigenous and surrounding communities, but climate change is in fact, the real human rights issue of the 21^st century and it affects everyone. By using …

When Addressing Climate Change, Don’T Forget Animal Agriculture, Aaron Matzke

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

As COP 21 closes in Paris, global animal agriculture is a topic that has eluded the international media. Animal agriculture is responsible for more global greenhouse gas emissions than transportation according to the U.N.’s Food and Agriculture Organization. With global population and prosperity rising, the global meat supply is expected to nearly double by 2050. This increase in production will only be achieved if significant steps are taken to promote sustainability through existing techniques globally, and to regulate air contamination in industrial feedlots in the United States. Alternative meat production methods, which have seen considerable investment recently, could supplement animal …

U.S. Vehicle Efficiency Standards, Derek Baylog

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

The United States is a driving force of the global economy and a major innovator in the technology sector. For decades the world has looked to The United States as a leader of great technological advancements with the strong economy to allow investors a chance make these technologies a reality. So why is it now that we lag behind other countries when it comes to making our technology energy efficient? Sure we’ve been steadily growing our production of renewable resources with wind and solar energy, bet we are still behind in the second largest source of pollution, transportation. According to …

Energy Subsidies And The Future Of Power, Christian Jewett

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

The modern political climate has grown rife with talk concerning the use of fossil fuels as an energy source and how this may impact our planet for generations to come. The Left and the Right seem to be at odds over whether or not climate change is actually occurring, or who is causing it. Additionally, the energy industry likes to tout their “low-cost” energy sources as a boon to the global economy as well as a benefit to the consumer at large. However, are coal, oil, and natural gas truly the “cheapest” sources of energy? Whether or not one believes …

Making Walkable Communities, Katie Zuehlke

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

There is no doubt that global warming is happening. With all the rage about climate change and global warming people should be doing more about it than just reading about it in the news. We should be making efforts towards making changes on a local level. This in turn could grow to a national level with more and more people participating in the movement and actually make global changes, instead of just talking about it. When the scale of participants grows the scale of the changes made will grow as well and this will be the beginning of the changes …

Incentives Critical To Full Wind Power Potential In Nebraska, Michael Neale

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

On August 3rd, President Obama and the EPA announced the Clean Power Plan (CPP) with the goal of cutting 32% of carbon emissions nationwide by 2030. The plan institutes carbon reduction requirements for all states based on their current sources of energy, for Nebraska the goal is 40%. The next day, Governor Ricketts and his Attorney General announced they would be fighting the mandate in court; stating the plan is unlawful federal government overreach, while expressing concerns the reduction are infeasible in the timeframe given and will drive up electricity costs. Governor Ricketts misses the point on this. Reducing carbon …

The Tax Of The Century, Anna Wistrom

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

The current economic standing of the United States is nothing like it was back in the 20’s when “business was booming”. There are some businesses today that are still above water despite these difficult times and they are mainly fossil fuel companies. The United States, along with other develOp-ed and developing countries, has a strong and crippling addiction to these cheap and dirty fuels. The goal of several recent environmental conventions has been to find a way to decrease the amount harmful gas that is emitted from these fuels into our atmosphere. Clean energy technologies always seem to be the …

Our homes are one of our most prized possessions, because of the many things it provides. Trying to keep your house from falling apart, can seem like a never ending task. If you neglect these tasks your house can go from a home to a death trap very quickly. While your house is your home, the earth is home to you, your home, along with generation yet to be born. Just like your individual home, the earth requires tasks to be done to keep it from killing us all. Today addressing the problem of greenhouse gases (GHG) emissions needs to …

The Clean Power Plan Needs To Be A Law, Mitchell Frischmeyer

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

The Clean Power Plan (CPP) is a long overdue policy which is necessary to direct national investment in emerging markets and create an intelligent energy infrastructure that strives to operate at max efficiency. To this point, the US has develOp-ed using inefficient and dirty fuels, a method which allowed for cheap and reliable energy generation, but is largely responsible for the change in global climate. If we expect to prevent climate change, our energy infrastructure must be reformed. Countries like Denmark have led the way in energy reform by creating policies set to reach 100% renewable generation by 2050 (8). …

Wetland Inundation Mapping And Wetland Restoration Planning: A Case Study Of Playa Wetlands, Nebraska, Yue Gu

Community and Regional Planning Program: Theses

There has been a variety of wetland monitoring projects implemented in playa wetlands in Nebraska over the last decades. But there is still a lack of continuous wetland monitoring on long-term and large-area dimension. Because inundation condition is one of the critical parameters to describe wetland hydrologic performance, this study aims to assess the inundation alteration in playa wetlands in Nebraska and evaluate the performance of wetland conservation and restoration practices. This study uses the Landsat data to create playa wetland inundation condition maps and analyze the variation trend of inundated playa wetlands over the past 30 years. The results …

Current Status And Long-Term Trends In Water Quality And Living Resources In The Virginia Tributaries And Chesapeake Bay Mainstem From 1985 Through 2014, Daniel M. Dauer, Todd A. Egerton, John R. Donat, Michael F. Lane, Suzanne C. Doughten, Cindy Johnson, Monika Arora

Status and Trends for Virginia Chesapeake Bay

The period prior to the implementation of the Chesapeake Bay Monitoring Program was characterized by a marked decline in the water quality of the Chesapeake Bay. The disappearance of submerged aquatic vegetation in certain regions of the Bay, declines in the abundance of some commercially and recreationally important species, increases in the incidence of low dissolved oxygen events, changes in the Bay's food web, and other ecological problems have been related to the deteriorating water quality (e.g. USEPA, 1982,1983;Officer et al.,1984; Orth and Moore, 1984). The results of concerted research efforts in the late 1970s and early 1980s stimulated the …

Occupancy Analysis And Density Estimation Of Kori Bustards (Ardeotis Kori) And Helmeted Guineafowl (Numida Meleagris) For Use In Landscape Conservation Planning In The Northern Tuli Game Reserve, Botswana, Kathryn R. Mccollum

School of Natural Resources: Dissertations, Theses, and Student Research

For understudied species, more informed conservation planning and decision-making on both the local and landscape levels may be attained through the use of occupancy and abundance estimations. Here, we focus on two iconic bird species in eastern Botswana, kori bustards (Ardeotis kori) and helmeted guineafowl (Numida meleagris). The overall goal of this project was to better understand the hierarchy of factors that influence occupancy (ψ) and density of kori bustard and helmeted guineafowl populations within the Northern Tuli Game Reserve and how these factors may interact to affect landscape conservation and usage. We performed distance sampling …

Macrobenthic Communities In The Northern Gulf Of Mexico Hypoxic Zone: Testing The Pearson-Rosenberg Model, Shivakumar Shivarudrappa

Dissertations

The Pearson and Rosenberg (P-R) conceptual model of macrobenthic succession was used to assess the impact of hypoxia (dissolved oxygen [DO] ≤ 2 mg/L) on the macrobenthic community on the continental shelf of northern Gulf of Mexico for the first time. The model uses a stress-response relationship between environmental parameters and the macrobenthic community to determine the ecological condition of the benthic habitat. The ecological significance of dissolved oxygen in a benthic habitat is well understood. In addition, the annual recurrence of bottom-water hypoxia on the Louisiana/Texas shelf during summer months is well documented.

The P-R model illustrates the decreasing …

Recreation Ecology Of Colorado Fourteeners: An Assessment Of Trail Usage And Impacts, James C. Ewing

Master's Theses

The popularity of climbing Colorado’s 14,000 ft. peaks, or “Fourteeners”, has risen dramatically in recent years, raising important sustainability and management questions. Moreover, groups managing the peaks operate with major capital constraints so their efforts need to be informed, prioritized, and efficient. This paper gauges the dynamics of trail usage, explanatory variables, and recreational impacts across all 58 Fourteeners, and details evaluation adjustments that minimize error and produce results in-step with the resource management framework. Relative to a baseline study completed in 2005, substantial changes occurred in trail usage and impact dynamics. The greatest changes were concentrated on peaks previously …

Seismic Surveys And Marine Turtles: An Underestimated Global Threat?, Sarah E. Nelms, Wendy Dow Piniak, Caroline R. Weir, Brendan J. Godley

Environmental Studies Faculty Publications

Seismic surveys are widely used in marine geophysical oil and gas exploration, employing airguns to produce sound-waves capable of penetrating the sea floor. In recent years, concerns have been raised over the biological impacts of this activity, particularly for marine mammals. While exploration occurs in the waters of at least fifty countries where marine turtles are present, the degree of threat posed by seismic surveys is almost entirely unknown. To investigate this issue, a mixed-methods approach involving a systematic review, policy comparison and stakeholder analysis was employed and recommendations for future research were identified. This study found that turtles have …

Increased Taxonomic And Functional Similarity Does Not Increase The Trophic Similarity Of Communities, Thomas K. Pool, Julien Cucherousset, Stéphanie Boulêtreau, Sébastien Villéger, Angela L. Strecker, Gaël Grenouillet

Environmental Science and Management Faculty Publications and Presentations

Aim: Despite a long-standing research interest in the association between the biodiversity (i.e. taxonomic and functional composition) and trophic structure of communities, our understanding of the relationship remains limited. Community assembly theory predicts that niche partitioning will result in communities with a diverse array of functional traits, which in turn may facilitate a correspondingly diverse array of trophic interactions that define the trophic niche of those communities. The aim of our study is to test this prediction.

Methods: We built a database composed of functional traits and stable isotope values (δ¹³C and δ¹⁵N) for …

Patterns Of Anthropogenic Nutrient Contaminants In The Otter Creek Watershed, Madison County, Kentucky, Elijah D. Wolfe, Walter S. Borowski, Jacob L. Robin

EKU Faculty and Staff Scholarship

We measured nutrient concentrations within the Otter Creek watershed (Madison County, Kentucky) to: (1) discover levels of anthropogenic contaminants affecting the water quality; (2) compare these measurements to a national data set; and (3) identify nutrient sources. The watershed mainly drains rural land characterized by cattle grazing, but also drains the town of Richmond. We sampled throughout the watershed to gain a representative perspective of nutrient levels and specifically targeted localities of suspected anthropogenic nutrient sources. Water samples were passed through a 0.45 mm filter, placed in pre-acidified vials, and measured one to two days after collection. Nutrients – ammonium, …
