Evaluating The Effect Of Garden-Based Education On Young Learners’ Preferences For And Willingness To Try Healthy Food, Sierra Gregory

Agricultural Economics and Agribusiness Undergraduate Honors Theses

Childhood obesity in American children has tripled in the last 20 years, and 85% of current healthcare spending is linked to diet-related diseases. The consumption of highly processed foods is linked to these trends and makes up more than half of an average American youths’ diet. Reducing the consumption of highly processed foods in children’s diets can be addressed, in part, by addressing childhood neophobia (willingness to try new foods) associated with whole foods like fruits and vegetables. Influence over behavioral areas such as nutrition and in early childhood is essential to long-term sustained health, and garden-based interventions shows promise …

Social Media Impacts On Arkansas Consumer Perceptions Of Gmos, Elizabeth R. Berner

Graduate Theses and Dissertations

This study builds upon previous consumer perceptions of GMOs studies. A need existed to determine what, if any, effects social media messages about GMOs had on consumer perceptions in Arkansas. The study utilized a qualitative approach with three focus groups. Data were analyzed using descriptive code. Participants were found to have a general understanding of GMOs, though discussion about what a GMO product was took an uncertain tone. Most participants did not consider GMOs as a factor when purchasing products. Rather participants considered characteristics such as price, quality, and convenience. Participants did not believe the infographics had changed their opinions …

Precision Agriculture offers tools that can be used to optimize crop management practices globally. However, stakeholders’ perceptions and the lack of data-driven site-specific recommendations limit stakeholders’ ability to fully harness the potential benefits of PA. Identification of stakeholder needs and approaches to …

Do Fas Large Export Sales Reports Move Commodity Futures Markets?, William Johnson

Graduate Theses and Dissertations

This study sought to determine if the Large Export Reports from the USDA Foreign Agriculture Service have any discernible market-moving impact on particular commodity futures markets. The effect of the reports on futures markets is investigated using four different methods: the average return event study approach, the multiple regression with binary variables model, the autoregressive time series model, and the event spline model. The average returns showed that the FAS's Large Export Sales Reports had no influence on the pricing of wheat futures, but did have a considerable impact on the returns from days before and after the release of …

Density And Occupancy Of Mammals Along An Urban To Rural Gradient In Northwest Arkansas, Leah E. Mctigue

Graduate Theses and Dissertations

Human development is a rapidly expanding phenomenon impacting wildlife communities globally. As the human footprint expands, natural greenspace and nature reserves become fragmented and isolated. Wildlife species and communities respond to these changes in different ways. Urban exploiters persist in more urban areas and are able to take advantage of anthropogenic subsidies (food, shelter, etc). Urban avoiders, however, are species that may be pushed out of developed areas or occur in lower densities relative to undisturbed areas. Northwest Arkansas is an optimal location to study the impacts of urbanization on wildlife communities, as the current human population is expected to …

Decrypting The Processes Of Policy Evolution: Comparing Québec And Ontario’S Evolution Of Risk Management Policies, Frederick Clerson Guicherd

Graduate Theses and Dissertations

Through policies or programs, states can influence industries to align with their vision of what a sector should become. However, this vision is subject to influence from actors of the industries which emphasize the importance of the relationship between the state and interest groups. In this dissertation, we observe the evolution of 9 Canadian agriculture risk management programs implemented by two provincial governments between 1990 and 2020 to understand how such programs coped with the new trends in agriculture. Through a review of parliamentary discussions and official documents, we evaluate the factors that justified program evolution based on the combination …

The Future Of Public And Private Plant Breeding According To Plant Scientists, Lexie Burris

Graduate Theses and Dissertations

Plant breeding has been effective in addressing food insecurity by increasing agricultural yields and productivity. Historically, public plant breeding programs have long-term, integrated approaches to plant breeding research, germplasm enhancement, and variety development, but as funding is reduced the future is less certain as to areas of focus. This survey builds off those before it and asks the next logical question, if a divergence between private and public breeding is taking place, what aspects should each sector focus on? The impetus of this study was to ask opinions of plant breeders globally regarding the direction they believe the public and …

Risk-Returns Of Forward Contracting Southern Row Crops With Crop Revenue Insurance, Chandan Bhattarai

Graduate Theses and Dissertations

This study evaluated the risk and return associated with various levels of forward contracting for southern row crops, specifically corn, soybean, and rice, in conjunction with different coverage levels of the Revenue Protection (RP) crop insurance program and government support plans. Forward contracting is a strategy to manage price risk by transferring ownership of physical grain from a seller to a buyer at a pre-agreed time. RP is a return-based crop insurance program offering coverage levels ranging from 50-85 percent in 5 percent increments, which allows producers to hedge against yield or price risks. Additionally, the study analyzed the effectiveness …

Beef And Dairy Substitution Effects Associated With Carbon Labeling And An Information Intervention, Sara Gardner Hedgecock

Graduate Theses and Dissertations

Understanding consumer perceptions of carbon emissions in agriculture is a critical step to help increase the sustainability of food consumption. According to the Food and Agriculture Organization of the United Nations, 14.5 percent of all global anthropogenic GHG emissions are estimated to be represented by livestock (FAO), and cattle, raised for beef and milk, are the largest animal species responsible for emissions, comprising over 60 percent of the livestock sector’s emissions. This motivates this study’s analysis of beef and dairy milk products and alternatives. To better understand how consumers may substitute meat and milk products when provided with information about …

Factors Affecting Food Security And Participation In Food Pantries In The U.S., Alexis Jade Skinner

Graduate Theses and Dissertations

Given the rise in food inflation, reduction of SNAP benefits, and the increased demand for food pantry participation, a more holistic understanding of potential barriers to obtaining assistance from non-Federally regulated food pantries is warranted. In May of 2022, 625 surveys were administered to low-income participants in the United States who participated in food collection from a food pantry in the previous month. Those participants were asked to select what information they were asked to provide during their visit, including home address, place of employment, Social Security card, driver’s license, household size, blood test, or others. Some forms of the …

Consumer Valuation Of Rice Quality In Colombia, Juliann Phillips

Graduate Theses and Dissertations

Rice is a crucial contributor to global food security and is an important staple for over half the world’s population. In Colombia, total rice consumption has grown by 25% in the last decade (2011-2021), reaching 1.9 MMT in 2021, yet in 2021 around 15.5 million Colombians were classified as food insecure. Colombia is the third largest rice producer in Latin America, producing 1.8 million metric tons (milled basis) in 2021. Increasing rice consumption coupled with high levels of food insecurity highlights the necessity that rice markets effectively price rice according to consumer preferences. Therefore, the goal of this study focuses …

Ireland V. United States: Agricultural And Environmental Sustainability Policies, Lauryn O'Grady

Accounting Undergraduate Honors Theses

The United States and Ireland have varying practices to achieve similar objectives in regard to environmental sustainability. While the European Union has maintained and updated a uniform policy throughout its existence--the Common Agricultural Policy--the United States instead created short-term solutions to a long-term problem. Not only does the United States tend to solve issues in the short-term, the policies between agricultural production and environmental sustainability are not necessarily aligned or remotely relative to the other. While the United States’ new Global Food Security Strategy implements parts of both agricultural and environmental sustainability, much of the history was not based off …

Understanding The Operations And Decision-Making Of Cow-Calf Farmers In Northwest Arkansas, Clayton Weyl

Agricultural Economics and Agribusiness Undergraduate Honors Theses

Societal pressure on farmers has become a more central part of the rhetoric surrounding livestock production. This study includes farmers in the discourse on the rhetoric surrounding climate change via interviews and simulations tailored to their operation. Previous research has addressed regenerative agricultural practices and conditions that influence farmer decision-making, but little research has analyzed decision-making in tandem with environmental practices. The literature reveals that cow-calf producer decision-making is influenced by their reliance on cattle as an income source, and farmers overall choose climate-friendly practices based on their perceptions about climate change. The goal of this research was to gather …

Solar Grazing As A Possible Vegetation Management Solution: A Budget Analysis, Byron Louk

Agricultural Economics and Agribusiness Undergraduate Honors Theses

A growing response to climate change among agricultural producers is to integrate renewable energy production in their portfolio of enterprises. Nonetheless, land use competition for agricultural production and solar energy production exists. To alleviate some of this competition, and possibly generate income for sheep grazers, photovoltaic (PV) system operators may save on operations and maintenance by grazing forages under solar panels rather than using mechanical or chemical means of vegetation management. “Solar grazing” operations have been shown to be economically feasible for PV system operators who own the land and pay for sheep grazing as a method of vegetation management, …

Loan Survival: Are Socially Disadvantaged Farmers More Likely To Default Or Pay In Full?, Marie-Cécile Vekemans

Graduate Theses and Dissertations

This study aims at identifying racial and gender discrimination in the usage of credit for Socially Disadvantaged Farmers and Ranchers (SDFR) in the United States. Usage of credit is considered successful when a loan has been paid in full and a failure is considered when the borrower defaults. Identifying such a pathway would provide useful information to the Federal government United States Department of Agriculture (USDA) Farm Service Agency (FSA) to evaluate the effectiveness and equity of loan programs. This study uses data from the USDA FSA farm loan programs that mainly target socially disadvantaged farmers and other underserved groups. …

The second article estimates the effects CA provides to adopters and their farms in smallholder farming systems in the DRC, focusing on changes in soil properties and cowpea (Vigna unguiculata) yields. The final article uses a Life Cycle Assessment (LCA) approach to monetize the environmental impacts of adopting …

Discrete Choice Experiments In Agricultural And Food Economics: Two Essays On Information Provision Modalities, Uncertainty Adjustment, And Hypothetical Bias, Monsoïa Arsène Juste Agossadou

Graduate Theses and Dissertations

Stated discrete choice experiments are extensively used in applied economics to study preferences and valuation for new products, as well as costs and benefits of new policies and programs. Moreover, information provision experiments widely use the method to examine information effects on different outcomes. This thesis explores two methodological issues in discrete choice experiments: (i) information provision modalities and (ii) hypothetical bias. The first study examines the effect of information modality by testing the effect of using combined text script and audio clip (treatment) versus only text script (control) to convey information in discrete choice experiments. Specifically, the study elicits …

Factors Affecting Graduation With Honors: A Case Study In Business, William Litzinger

Agricultural Economics and Agribusiness Undergraduate Honors Theses

Many first-year college students elect to enroll in their university’s honors program. These programs offer students many educational benefits not provided to non-honors students, such as smaller class sizes, priority registration, and added faculty interaction. However, of the students that enter the university as an honors student, many fail to complete their honors program. Researchers have documented completion rates as low as 18.45% (Campbell and Fuqua, 2008). So why are honors graduation rates so low? In this study, variables were examined that the literature suggests affects honors graduation rates (High School GPA, ACT/SAT scores, AP credits, GPA 1^st term …

Are Some Analysts Superior At Forecasting World Grain Supplies?, Emmie M. Noyes

Agricultural Economics and Agribusiness Undergraduate Honors Theses

Whether agriculture is how you make your living or simply a means of putting food on your table, the prices of agricultural commodities and products affect us all. When buying and selling agricultural commodities, both farmers and firms use futures markets. Futures markets help minimize price risk, which is important to both sides of the transaction.

Recently, private analysis firms have started to forecast the information contained in the USDA’s WASDE report. This is relevant because future prices react to new information contained in WASDE reports. These firms will release their information a few days before the WASDE comes out …

Consumer Preferences For Lab Grown Meat: The Effect Of Information On Consumer Choice, Aryn Blumenberg

Food Science Undergraduate Honors Theses

Global population growth and increased meat demand present challenges for the agricultural industry to produce meat sustainably. In-vitro meat (IVM) is an alternative that could reduce negative impacts associated with livestock production. The goal of this study was to examine consumers’ preferences for IVM. A choice experiment was created with twelve choice tasks that varied across five attributes: production method (IVM or conventional), carbon trust label, organic label, animal welfare label, and price. 1,120 US consumers were randomly assigned to one of four information treatments, differing by information presented regarding IVM: 1) neutral (baseline), 2) positive, 3) negative, and 4) …

Economic Viability Of Weed Management Strategies In High-Tunnel Tomato, Gracie Morrison

Crop, Soil and Environmental Sciences Undergraduate Honors Theses

Cost-effective weed suppression is an important consideration for tomato growers. Growers often choose methods which minimize hand labor, as hand weeding can be prohibitively expensive. This project determined economic viability of high tunnel tomatoes treated with several methods of weed control, both organic and chemical. These methods included: 2-week hand weeding, 1-week hand weeding, preemergent, straw, landscape fabric, and untreated weedy control plots. These treatments were applied to randomized blocks in a high-tunnel. Weeding, planting, and harvest were all timed to determine labor and material costs of weed management strategy implementation. After harvest, marketable yield was weighed to determine revenue. …

The Work Of La Via Campesina Regarding The Intersection Of Land Occupation And Food Sovereignty, Josephine Drydale

International and Global Studies Undergraduate Honors Theses

La Via Campesina (LVC), a global movement that supports small and local farmers and their communities, is one of the world’s largest food and agricultural rights movements and advocates for agricultural rights in terms of land, ecology, human rights, and more. LVC is known for its establishment of food sovereignty, defined as the right to control one’s production and consumption of food. This new concept placed them on the map, accompanied by their aggressive editorial and advocacy work against ideals they view as neoliberal and food policies that benefit large food moguls while disenfranchising the small farmer. The concept of …

The Last Leg: A Social Sustainability Assessment Of Ovine Agriculture, Sydney Golding

International and Global Studies Undergraduate Honors Theses

Post-war agricultural transformations and the rise of Sustainability discourses have dictated the trajectory of sector industries. The implications of agriculture in lateral policy schemes have neglected the careful consideration of the social health of farmers in decision-making processes, creating a greater divide between the interests of the state and our once revered providers. This study aims to capture the complexity of social matters in agriculture within the specific context of sheep farming in the United Kingdom and the United States and how the concurrent systems have adapted considering the impacts of relevant contemporary historical contexts. The principles of Janker, Mann, …

Economic Potash Fertilizer Rate Recommendations, Kimberly B. Oliver

Graduate Theses and Dissertations

This thesis is comprised of two studies that estimate profit-maximizing potassium (K) fertilizer application rates for various crops across different time periods. Estimation of profit-maximizing fertilizer-K rate (K*) for both studies considered the initial soil test level of K (STK) and yield response information, as traditional recommendations do, and added crop price and the cost of fertilizer. Profit maximum occurs where the marginal revenue from additional yield is equal to the marginal cost of applying an additional unit of fertilizer-K. The first study calculated K* for corn (Zea mays) and cotton (Gossypium hirsutum) and compared results to previous studies on …

Comparing Organic And Conventional Yield Responses To Climate Variations, Joost Wilken Meyer

Graduate Theses and Dissertations

This thesis compares the responses of organic yields and conventional yields towards climate variations. To achieve this objective, weather variables such as growing season weather conditions (average temperature, precipitation, cloud cover, relative humidity, drought index), weather anomalies, the occurrence of severe or extreme droughts and excessive rainfalls, are combined with 23 data sets gathered from previous studies that compare organic and conventional yields from the same location and time periods. To narrow the scope, the thesis focuses on soybean, maize, and wheat production in Europe and North America. Study-level fixed-effects models are used to control for any time-invariant factors such …
