Developing An Ecological Sanitation Transect, Ian Kolesinskas

Masters Theses

A sanitation problem exists for people across the globe: basic human waste collection and treatment is inaccessible to much of the world’s population; and the status-quo gray infrastructure system of sanitation is unsustainable and unsuitable for widespread application. A paradigm shift is needed: this thesis makes the case for developing an Ecological Sanitation Transect to bring back the closed loop that connects consumption, waste excretion, sanitation, and food production. The Ecological Sanitation Transect is a synthesis of ecological sanitation, where human excreta is reused, and the urban transect, where development density is conceptualized along a continuum from rural to urban. …

Spatial And Temporal Impacts Of Incentive Payments For Forest-Based Carbon Sequestration, Juhee Lee

Masters Theses

This thesis consists of two essays on impacts of incentive payments for forest-based carbon sequestration, focusing particularly on spatial and temporal aspects in the first and second essays, respectively. The purpose of the first essay is to determine if a county-level tax-based subsidy approach is a valid alternative to existing subsidy approaches for forest carbon sequestration. A land use change model is used to test the hypothesis based on a case study of Bureau of Economic Analysis Area 88 (BEAA 88). The empirical results show that the increased net return from waiving the property tax increases the share of forestland …

Essays On Analysis Of Electricity-Price Policy, Sanguk Kwon

Masters Theses

Effects Of Noncommercial Open Interest On Corn And Soybean Futures Price Volatility, William Grady Ferguson

Masters Theses

Since the early 2000s a dramatic rise in institutional investment in agricultural futures markets has occurred. This rise may have caused an increase in price volatility, potentially resulting in added risk for farmers, agribusinesses, and consumers. Currently, regulators, hedgers, exchanges, and speculators lack information regarding how modern investments in agricultural futures markets affect short-term price volatility. The objective of this analysis is to examine the effect of institutional investment on short-term price volatility for corn and soybean futures markets. Using daily price data for corn and soybean futures from the Chicago Board of Trade (CBOT), several measures of price volatility …

Effects Of Optical Sensing And Variable Rate Technology On Nitrogen Fertilizer Use, Lint Yields, And Profitability In Cotton Production, Melissa Reynolds Stefanini

Masters Theses

Nitrogen (N) fertilizer is expensive and can be harmful to the environment. Precision agriculture (PA) has the capability to reduce the amount of excess N from crop production released into the environment, increase net returns to the grower, and reduce the risk of profit loss due to spatial and temporal variability. The objectives of this study were to evaluate the profitability, risk management potential, and N use efficiency of using real-time optical sensing with variable-rate technologies (VRT) to manage spatial variability in cotton production.

Cattle Producers East Of The 100th Meridian: A Study Of Afforestation Adoption And Use Of Pasture Management Practices, Hannah Sage Claytor

Masters Theses

This thesis explores two topics related to cattle producers: the adoption of afforestation on pastureland and the use of pasture management practices. Chapter 1 uses a triple hurdle model to analyze a decision process related to the adoption and acreage enrollment of afforestation in a hypothetical program. The results suggest that producers interested in afforestation are more likely to have a college degree, own woodland, attend extension workshops, and have previous experience with afforestation. Producers who were offered a lower incentive enrolled more acres in the hypothetical program. Producers who were offered a higher incentive enrolled fewer acres.

Chapter 2 …

Locational Advantage And The Impact Of Scale: Comparing Local And Conventional Fruit And Vegetable Transportation Efficiencies, Charles Cate Grigsby

Masters Theses

Fresh produce in the United States often travels thousands of miles in diesel operated semi-trucks before arriving to market. Under a high fuel cost scenario, the current low-cost, efficient supply chain could become a high cost organizational structure for US food distribution. Rising transportation costs of food sourced from distant locations may provide competitive opportunities for small- and mid-sized local producers if transportation costs are a smaller portion of their total costs. Farmers selling fresh produce in east Tennessee farmer markets are surveyed to obtain baseline information on their transportation energy use to deliver their products to market. Local farmer …

Solar Pv Adoption In The United States: An Empirical Investigation Of State Policy Effectiveness, Ilya Chernyakhovskiy

Masters Theses

State policy incentives for solar power have grown significantly in the past several years. This paper examines the effectiveness of policy incentives to increase residential solar PV capacity. County-level solar adoption data and controls for demographic characteristics, solar resources, and pro-environmental preferences are used to estimate a model of residential solar adoption. Empirical findings show that financial incentives, solar-specific mandates, and loan financing programs are important drivers of residential PV capacity growth. Incentives that reduce the up-front cost of adoption and that are subject to low uncertainty are found to have the largest impact. Results also point to a significant …

Tennessee Consumers’ Willingness To Pay For Beef Produced In Tennessee, Leah Moore Dobbs

Masters Theses

Little is known about Tennessee consumer willingness to pay (WTP) for beef produced in the state or about the type of outlet where they would expect to purchase Tennessee beef. Tennessee beef cattle production and sales decision making can be guided by the willingness to pay of consumers, demographics profiles of those willing to pay a premium for Tennessee beef, and outlet choice for purchasing local beef. A telephone (land-line and wireless) survey of major metropolitan areas in Tennessee was conducted in 2013 to collect data from a total of 1,209 respondents. This data is used in probit models to …

Results suggest that physical activity is most beneficial for mild and moderate depressed individuals and the …

“Common Sense” Versus “Good Sense”: Marginalization In Agriculture, Mark W. Hoock

Masters Theses

Scholars have engaged in discussions of when and where capitalism emerged in agrarian America. These discussions have led to categorizations that placed some farms outside the discussion of capitalist interrelationships. This separation homogenized many 19^th and early 20^th century farms on the Hector Backbone in Schuyler County New York into a “non-capitalist” category. This thesis aims to illuminate the real lived conditions of a sample of these farmers through a Marxist dialectical perspective. Archeological analysis of production strategies, through a Marxist framework allows for a better understanding of the differences between individual marginalized farms. Since analysis of a …

Assessing The Influence Of Conservation Agriculture On Household Wellbeing And Maize Marketing In Tete And Manica Mozambique, William Edward Mcnair

In recent years there has been a movement on the part of farmers, governments, Non-Governmental Organizations (NGO), and the international community to promote the use of sustainable agricultural practices. In Sub-Saharan Africa, this has translated into programs with the expressed aim of increasing smallholder farmer adoption rates of conservation agriculture (CA). This thesis contributes to the analysis of the adoption of conservation agriculture by smallholder farmers in Sub-Saharan Africa by assessing the economic status of CA adopters in the providences of Manica and Tete, Mozambique.

Chapter II of the thesis examines the ceteris paribus correlation between smallholder farm household economic …

A Gis-Based Multi-Objective Optimization Of A Lignocellulosic Biomass Supply Chain: A Case Study In Tennessee, Zidong Wang

Masters Theses

To achieve an economically and environmentally sustainable lignocellulosic biomass (LCB)-based biofuel industry sector, the design and location of a sustainable LCB supply chain is important. In this study, a multi-objective optimization model integrated with high-resolution geographical data was developed to examine the optimal switchgrass supply chain for a potential biorefinery in Tennessee, specifically evaluating the potential tradeoffs between the objectives of minimizing plant-gate cost and GHG emissions from the switchgrass supply chain. The key findings of this study are as follows: both plant-gate feedstock cost and GHG emissions were sensitive to the type of land converted into switchgrass production, the …

Switchgrass Capacity Procurement Contract And Tonnage Contract Pricing, Tianpeng Zhou

Masters Theses

The on-farm production of switchgrass has been given considerable attention by farmers, policymakers and others. However, because the switchgrass market is not developed yet, most of the research only focuses on the switchgrass breakeven cost. The appropriate price combining interests of both the biorefinery and the farmers, or the contract price, has not been given enough attention.

Two types of contractual relationships are discussed in this thesis: Capacity Procurement Contract (CPC, per acre contract) and Tonnage Contract (TC, per ton contract). The contract prices of switchgrass under these two types of contracts are estimated in this analysis. Because the land …

Intensity Of Adoption Of Direct Marketing Strategies Among Fruit And Vegetable Farmers In Tennessee, Carey Ann Wolanin

Masters Theses

Consumer interest in fresher foods has increased over the past few years and has stimulated the growth of direct-to-consumer outlets. Tennessee currently hosts many types of direct food outlets, including farmer markets, CSAs, roadside stands, and pick-your-own operations. Using data from a 2011 survey of Tennessee fruit and vegetable producers, factors associated with the percentage of sales fruit and vegetable producers make through direct-to-consumer outlets or intensity of adoption of direct-to-consumer marketing strategies are evaluated using fractional logit and logit regressions. Findings suggest that the percentage of sales a producer makes through direct-to-consumer outlets is associated with farmer age, the …

Essays On Spatial Analysis Of Policy Impacts, Daegoon Lee

Masters Theses

This thesis is composed of two essays under the theme of spatial analysis of policy impacts. The objective of the first essay was to analyse how population dynamics affect greenhouse gas (GHG) emissions. The effects of population redistribution resulting from the South Korean government’s decentralization efforts on GHG emissions were assessed. Simulation results suggest that the direction of change in total GHG emissions depends on the share of the population redistributed from higher to lower population density regions. If the entire redistributed population of 877,000 persons expected from the government’s decentralization project were from the Seoul Area, annual CO_{2 …}

Data Anti-Suppression Methods And An Application Of Spatial Concentration Measures To Evaluate Green Energy Value Chain Concentration, David Lane Register

Masters Theses

A number of renewable, or so-called “green energy” products have emerged in response to the environmental, national security, and economic risks posed by the consumption of fossil fuels. The development of the renewable fuels sector, including ethanol, biodiesel, landfill and dairy methane gas, and solar and wind energy have also been considered potential sources of economic growth. But continuously changing market and policy conditions put at risk recent accomplishments in green energy sector development, thus placing a greater emphasis on efficient coordination between producers and suppliers.

Recent advances in firm location theory have produced a variety of analytical tools to …

Examining Impacts On Water Demand Resulting From Population And Employment Growth Using A Regional Adjustment Model, Steven Blake Thomas

Masters Theses

This thesis examines the currently available water use data and its limitation for use in scientific research. The first chapter offers a description of the current nationwide water data including descriptions of collection methods and trends found within the data. The varying collection methods used result in inconsistencies within the datasets and between the years. These inconsistencies have resulted in the data being used more as a point of reference than in nationwide empirical analysis of water use. There has been a calling for systematic improvements to the data, which could contribute to greater empirical analysis taking place at the …

Analyzing Effects On Biofuels While Integrating The Agricultural Sector To The Energy Market: Linking Polysys And Markal, Shreekar Pradhan

Masters Theses

Two different sectoral models: POLYSYS (agricultural) and MARKAL (energy) are soft-linked in a modeling framework. The linkage benefits the strengths of price dynamics of biofuel crops in POLYSYS and the least cost biofuel supply in MARKAL. As the result the framework can now evaluate implication of biofuel policy in the agricultural and energy sectors simultaneously. This study utilizes the linkage to evaluate the implication of biofuel subsidy policy on the agricultural and energy sectors. Three scenarios are developed. First, the base case assumes current subsidy for corn ethanol and cellulosic ethanol will be continued until 2030. Second scenario (Sub1) assesses …

Residual Supply Analysis Of The United States Corn Export Market, Melissa Antoinette Yeast

Masters Theses

Six models of imperfect competition test the interaction between the United States and Argentina in the Japanese corn import market. The models evaluated were the Bertrand (1883), Cournot (1897), and Stackelberg (1952) with price and quantity leadership by the United States and Argentina. Models were compared using a non-nested likelihood ratio test. Results of the analysis did not show a statistically significant preference of one model over another. The dominance of the United States in the Japanese corn import market is the likely cause for the results. The methodology used in this analysis could be applied to alternate commodities such …
