A Year In Syntropy: Exploring Syntropic Agriculture, Ajah Eills
A Year In Syntropy: Exploring Syntropic Agriculture, Ajah Eills
College Honors Program
Syntropic agriculture is a form of sustainable agriculture that originated in Brazil around 25 years ago. Although it has since spread throughout Brazil and Australia, there has yet to be a comprehensive study of the driving scientific principles behind syntropy. For my thesis, I conducted literature research and interviews with farmers, with the goal of describing the ecological principles on which syntropy is based, including its primary goal to improve soil health. Much of my thesis contrasted syntropic agriculture with conventional agriculture as practiced in the United States today, but I also explored the differences between syntropic agriculture and other …
Compound Extreme Events, Radley Horton
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 …
International Migration From The Latin American-Caribbean Region: Taking Environmental Indicators Into Consideration, Chelsea Wepy
International Migration From The Latin American-Caribbean Region: Taking Environmental Indicators Into Consideration, Chelsea Wepy
Student Theses and Dissertations
International migration, the act of leaving one’s country to permanently settle in another country, is driven by many socio economic/political factors, such as lack of economic opportunity, access to education, governmental corruption, and violence. These factors have proven to be the reason that many citizens within the Latin American-Caribbean region either choose or are forced to relocate internationally. While these factors are important to consider independently; these issues are often exacerbated by changes in the natural environment. The objective of my paper is to highlight the importance of considering changes in the natural environment. In doing so, I hope to …
Investigations Involving Mononuclear And Dinuclear Transition Metal Catalysts For Photochemical Carbon Dioxide Reduction, Ansu Edwards
Investigations Involving Mononuclear And Dinuclear Transition Metal Catalysts For Photochemical Carbon Dioxide Reduction, Ansu Edwards
Honors Theses
There is currently a global energy crisis, which is in desperate need of solutions. New energy sources are required that will not pollute as much as our longstanding reliance on nonrenewable fossil fuels as an energy source. This pollution involves large amounts of greenhouse gas emissions, predominantly carbon dioxide (CO2), that contribute to environmental problems such as climate change. In this context, a fairly recent research direction to address this problem is the development of transition metal catalysts that can convert CO2 into reduced carbon products that can serve as chemical fuels. This work focuses on the …

Lesson Plan: Behavioral Plasticity, Center For Urban Resilience
Module 07: Animal Adaptation & Behavior
In the previous lessons, students learned about the importance of noise in the urban environment. In response to urban noise as well as other characteristics of urban ecosystems, organisms modify their existing behaviors to maximize their fitness and likelihood of survival. This lesson focuses on behavioral plasticity, which is the idea that organisms’ behaviors are flexible and can be modified in response to their environment. Students complete an activity in which they investigate the plasticity of their own behaviors. The class then discusses how this analogy is similar and different compared to urban species as well as how the plasticity …

Module 07: Animal Adaptation & Behavior
Species constantly engage in a variety of behaviors or activities that help increase their chance of survival. For example, a bird may build a nest or a coyote might communicate to other coyotes through howling. In this activity, you are going to explore the plasticity of behaviors – the ability of an organism to change or modify its behaviors based on the external conditions. Specifically, you will examine your own behaviors, but then consider how your behaviors would be similar or different from other species. You will then consider how the plasticity of an organism’s behaviors impacts its chance of …

Lesson Plan: Comparing Our Results, Center For Urban Resilience
Module 07: Animal Adaptation & Behavior
The purpose of this lesson is for students to compare their findings to that of other similar studies. The goal of the lesson is two-fold. First, students should understand the big idea that organisms living in urban ecosystems have modified their behavior in response to the impacts of the humans that live there. Second, this lesson should reinforce the concept of sample size as well as help students understand that we still have many gaps in our understanding of animals in cities.

Managing Climate Change And Weather Extremes For Nature-Based Tourism Organizations In The United States, Siyao Ma
Graduate Theses and Dissertations
Weather and climate serve as profound motivators for tourism travels. Much of the United States (US) has experienced a warming trend as well as higher extreme weather frequency, and the trends are projected to be continued. Consequently, the changing climate is expected to have both direct and indirect impacts on tourism decision-making and travel patterns due to the complex relationship between climate, weather, and outdoor recreation. Climate resources capture the integrated effects of varied meteorological variables that interact with humans in different ways and can be categorized along a spectrum of quantifiable values. This dissertation proposed a Camping Climate Index …
Organic Waste Bans: Beyond The Compost Heap, David Lee
Organic Waste Bans: Beyond The Compost Heap, David Lee
Journal of Food Law & Policy
Food waste and food insecurity are strange bedfellows, but in the United States they shamelessly walk hand-in-hand. The USDA’s Supplemental Nutrition Assistance Program (“SNAP”) and the Emergency Food Assistance Program (“TEFAP”) are two federal programs that provide for large numbers of people in the United States. Local food recovery and donation programs serve their communities as the “backbone of the America hunger response" efforts. While many American households continue to report their struggles with food insecurity, heaping piles of good food go to waste. The repercussions of wasted food are vast, taxing American wallets, wasting our resources with every bit …

The Pandemic, Climate Change And Farm Subsidies, Allen H. Olson, Edward J. Peterson
Journal of Food Law & Policy
Many people believe that once the COVID-19 pandemic has passed, life will return to the way it was. This belief is both unrealistic and dangerous. It is unrealistic because the virus will be around for years if not indefinitely. The timeframe for the worst of the pandemic will depend on our ability to administer effective vaccines worldwide and the public’s willingness to accept continued social distancing in the meantime. The damage done to public health, the economy and individuals is already substantial and will get worse. Recovery will be slow and incomplete. The belief that life will return to the …
Economic Feasibility Of Mixed Plastic Waste Pyrolysis Using Twin Reactor System In Northwest Arkansas, Carol Rogers, Patricia Means, Renato Gonzalez, Kaida Sheets, Hayden Townsend
Economic Feasibility Of Mixed Plastic Waste Pyrolysis Using Twin Reactor System In Northwest Arkansas, Carol Rogers, Patricia Means, Renato Gonzalez, Kaida Sheets, Hayden Townsend
Chemical Engineering Undergraduate Honors Theses
Plastic waste generation is increasing at an unsustainable rate while recycling solutions remain stagnant. As a chemical means of recycling, mixed plastic waste pyrolysis can generate synthetic oil appropriate for use as fuel in power generation from plastic waste that otherwise accumulates in landfills. With the scaling of a commercial plastic pyrolysis process in Northwest Arkansas (NWA) modeled after an operational sawdust pyrolysis unit in Huntsville, Arkansas, economic analysis resulted in 26.3% internal rate of return. Therefore, construction of a commercial mixed plastic-to-fuel pyrolysis plant is economically justified and should be pursued. To effectively implement the proposed design, NWA must …

Climate Change Preparedness In The Insurance Sector, Daniel Fischler
Honors Scholar Theses
Climate change is the inevitable consequence of human activity since the industrial revolution began centuries ago. Assuming humanity survives and adapts to this scenario, there will be significant impacts on the economy and business. Under these circumstances, the insurance sector in particular will face challenges as the frequency and severity of losses increase due to climate change related events. This paper aims to analyze various options for allowing insurance to maintain viability in this changing environment. The general issue for the future is premiums must be commensurate with climate change related risk in affected areas. As a result, certain coastal …
Economic And Ecosystem Impacts Of Gm Maize In South Africa, Kristiina Ala-Kokko
Economic And Ecosystem Impacts Of Gm Maize In South Africa, Kristiina Ala-Kokko
Graduate Theses and Dissertations
White maize in South Africa is the only staple crop produced on a widespread commercial basis for direct human consumption using genetically modified (GM) cultivars. Using a combined economic and environmental approach, we estimate the total welfare benefits attributable to GM white maize in South Africa for 2001-2018 are $694.7 million. Food security benefits attributable to GM white maize in South Africa also manifest through an average of 4.6 million additional white maize rations annually. To achieve these additional annual rations using conventional hybrid maize, the additional land required would range from 1,088 hectares in 2001 to 217,788 hectares in …

Long-Term Changes In Soil Surface Properties As Affected By Management Practices In A Wheat-Soybean, Double-Crop System, Machaela Morrison
Crop, Soil and Environmental Sciences Undergraduate Honors Theses
Long-term agricultural sustainability and productivity are controlled by the integrative effects of different management practices on the soil. Many Arkansas producers use the double-crop system to grow soybeans [Glycine max (L.) Merr] and wheat (Triticum aestivum L.). Studying combinations of different, non-traditional, alternative agricultural techniques may help producers better understand the long-term implications of various management practice options on sustainability and productivity. The objective of this study was to evaluate the effects of agricultural management practices, including residue level, tillage, irrigation, and burning, and soil depth on the change in various soil properties from 2010 to 2020 in …

A Comparison Of The Environmental Effects Of Renewable And Non-Renewable Energies, Jordan Moore
Crop, Soil and Environmental Sciences Undergraduate Honors Theses
This study presents current energy data from the United States and data from literature reviews to create life cycle assessments (LCA) for comparing the environmental impacts of wind and coal-fired energy generation and use. The environmental impacts were evaluated using emissions data, principally carbon dioxide emissions and carbon dioxide equivalents from methane. Other environmental impacts such as avian mortality and land use were compared as well. The LCA includes four phases: raw materials, transportation, use/retail, and waste. Overall, wind energy has a smaller environmental impact than coal-fired energy for the raw materials, transportation, use/retail, and waste phases. Wind energy resulted …
Examining The Benefits Of A Sustained Balance And Fall Prevention Programming For Independent Older Adults Living In A Community Setting, Noah Davis
Legacy Theses & Dissertations (2009 - 2024)
Falls have been an identified public health and social problem since the 1980’s and now recognized as a global health problem in many of the developed nations. The National Council on Aging and the Centers for Disease Control and Prevention acknowledge many evidence-based fall prevention programs. However, there are identified concerns to the programs; for example, a lack of sustained programming for older adults in the community setting. The literature review on fall prevention interventions identifies that few programs are sustained after two years, primarily due to a lack of funding and a lack of interest by older adults. However, …
