Modeling The Impact And Accelerating The Process Of Transitioning To A Sustainable Healthy Diet Through Decision Support Systems, Prince Agyemang

Graduate Theses and Dissertations

Food production and consumption are essential in human existence, yet they are implicated in the high occurrences of preventable chronic diseases and environmental degradation. Although healthy food may not necessarily be sustainable and vice versa, there is an opportunity to make our food both healthy and sustainable. Attempts have been made to conceptualize how sustainable healthy food may be produced and consumed; however, available data suggest a rise in the prevalence of health-related and negative environmental consequences of our food supply. Thus, the transition from conceptual frameworks to implementing these concepts has not always been effective. This paper explores the …

Optimization Of Broken Rice Consumption Through Understanding The Confluence Of Sensory And Economic Preferences, Matthew Greer Richardson

Graduate Theses and Dissertations

The authors were perplexed by the seeming dichotomy between the majority 70% of Haitian consumers being chronically food insecure, but still preferring to pay premium international market prices for long-grain rice that constitutes 30% of the calories in this poorest nation in the Western Hemisphere. The aim of this study was to determine the optimal percent broken rice in regards to price specifically to Haiti. Optimization between quality and price point is seen as the best rice for the price, and can be found through combining individual preferences with willingness to pay. Broken rice (brokens) garner a significantly discounted price …

Quality Determinates Of Rice Price In Open Bag Markets In Sub-Saharan Africa, Bailey Peterson-Wilhelm

Graduate Theses and Dissertations

Weaknesses in the grades and standards system in low-income countries across Sub-Saharan Africa undermine the transparency of agricultural markets. In the Democratic Republic of the Congo (DRC), Ghana and Mozambique rice is predominately sold in open bags and if rice price does not reflect its quality, then inefficiencies may lead to consumer welfare losses. Importantly, it is possible that impoverished communities are priced out of the market due to inflated and inefficient prices. The objective of this study is to examine determinates of rice price by estimating the impact of selected rice quality attributes on rice prices in DRC, Ghana …

Cost Effectiveness Of Greenhouse Gas Reductions Through Afforestation Of Agricultural Land In The Arkansas Delta, Karli A. Moore

Graduate Theses and Dissertations

Sequestration of atmospheric carbon in forested lands offsets carbon emissions from other industries. Conversion of private lands, particularly agricultural tracts in marginal areas, to forests can bolster carbon abatement. The United States government agencies administer some voluntary, incentive-based programs to encourage landowners to adopt production practices with positive environmental outcomes. This policy stream can be used to increase transition of marginal agricultural land to forests, thereby creating new carbon sinks. We analyze an eleven-county study area in the Arkansas Delta to determine feasibility for a subsidy focused on carbon abatement through afforestation. This study area is significant for two reasons: …

Assessing The Economic Viability Of Arkansas Farms Under The 2018 Farm Bill, Grant Wilson

Graduate Theses and Dissertations

For over a century, the American agricultural industry has relied on federal government support to aid in the maintenance and expansion of farming operations. Since 1933, a series of 18 farm bills have shaped agricultural policy into what is commonly known as the agricultural safety net. The 2018 farm bill was passed on December 20, 2018 and is the most recent update of the agricultural safety net. Commodity programs and federal crop insurance are two key components of today’s agricultural safety net, and many times, these programs may be the difference between a net loss and a positive net income …

Estimating Demand Elasticities For Rice In Benin, Ogoudele Simon Codjo

Graduate Theses and Dissertations

Rice consumption in Benin is increasing along with shifting consumer demand toward higher quality rice. In this context of changing demands, experimental estimation methods provide an effective way to estimate the current state of consumer preferences. We conducted a hypothetical choice experiment in 15 open markets in Benin to analyze the demand for rice and its substitutes. The results reveal that consumers value quality rice, even those in the low-income class. While high income consumers are more likely to choose high quality imported rice, low- and middle-income consumers are more likely to select high quality domestic rice among the set …

Producer Preferences For Alternative Irrigation Practices In The Arkansas Delta, Robert Edward Rosene

Graduate Theses and Dissertations

We use a bivariate sample selection model to address peer network effects on participation in and/or intensity of use of land being irrigated by alternative irrigation practices in the state of Arkansas. As groundwater in the state becomes more limited, the use of scientific scheduling, flowmeters, and more efficient row crop water application systems will allow producers to better manage water resources. We find relatively large, positive relationships between belonging to a peer network of the same irrigation practice and participation in that practice. Intensity of use of alternative irrigation techniques is mostly influenced by which crop type the practice …

Assessing Rice Consumers’ Preferences And Willingness To Pay In Haiti, Cleeford Pavilus

Graduate Theses and Dissertations

In the last 30 years, rice has become the number one food staple in Haiti, and rice imports have outpaced domestic production to supply the country’s increasing rice demand. Policy makers support the claim that increasing local rice supply will not only reduce the dependency on imported rice but also upheave the national economy. However, there is a lack of information on Haitian consumers’ preferences for rice to aid the development of the local rice supply chain. This research aims to bridge that gap by assessing Haitian consumer preferences and willingness to pay for selected rice quality characteristics. The results …
