Description Of 2011 Biofuels Policy Alternatives, Wallace Tyner

Global Policy Research Institute (GPRI) Policy Briefs

In the US, at the end of 2010 Congress extended the ethanol tax credit (VEETC) of $0.45/gal. for one year with the clear message to the industry and lobby groups that it wanted a long-term solution to be passed and implemented by the end of 2011. Following are some of the policy options that are being considered in 2011:

• Continue the 45 cent/gallon subsidy and the import tariff as at present
• Shift the subsidy from blender to biofuel producer
• Subsidy that varies with the price of crude oil or gasoline
• Subsidy based at least in part on ...

Economic Optimization And Precision Agriculture: A Carbon Footprint Story, Rachael M. Brown

Theses and Dissertations--Agricultural Economics

This thesis examines the economic and environmental impacts that precision agriculture technologies (PATs) can have on the carbon footprint of a grain farm. An analysis is offered using two manuscripts. The first examines the impacts of three PATs and compares the findings to a conventional farming method. It was found that all three PATs investigated showed a potential Pareto improvement over conventional farming. The second manuscript expanded the model used previously to in order to develop a process to construct a carbon efficient frontier (CEF). The model employed examined uniform and variable rate technologies. In addition to the CEF, a ...

Nanotechnology In The Food System: Consumer Acceptance And Willingness To Pay, Guzhen Zhou

Theses and Dissertations--Agricultural Economics

Nanotechnology is one of the key innovative technologies in the present century. The food industry has applied this technology in each of its sectors. Nanotechnology has tremendous potential in food and agriculture, including advancing agricultural cultivation and food production, enhancing food nutrition and flavor, and improving food packaging and preservation. However, the novel properties of nanoscale materials that allow beneficial applications are also accompanied with uncertainties, even unknown risks. A number of studies have examined public understanding as well as acceptance of nanotechnology via surveys in both the US and Europe. However, most of these studies concentrated on public attitudes ...

Economic Viability Of Shale Gas Production In The Marcellus Shale; Indicated By Production Rates, Costs And Current Natural Gas Prices, Ryan J. Duman

Theses and Dissertations

The U.S. natural gas industry has changed because of the recent ability to produce natural gas from unconventional shale deposits. One of the largest and most important deposits is the Marcellus Shale. Hydraulic fracturing and horizontal drilling have allowed for the technical feasibility of production, but concerns exist regarding the economics of shale gas production. These concerns are related to limited production and economic data for shale gas wells, declines in the rates of production, falling natural gas prices, oversupply issues coupled with slow growth in U.S. natural gas demand, and rising production costs. An attempt to determine ...

Exploratory Landscape Metrics For Agricultural Sustainability, Eric Vaz, Teresa Noronha, Peter Nijkamp

Geography Publications and Research

Socio-economic growth and urban change have been an increasing concern for decision makers in recent decades. The monitoring, mapping and analysis of agricultural land-use change, especially in areas where urban change has been high, is crucial. The collision between traditional economic activities related to agriculture in tourist areas such as the Algarve and current demand for tourism infrastructures in urban regions is also leading to loss of economic activity. This paper uses a combined Geographical Information System approach with CORINE land cover datasets to perform a Shannon’s diversity index quantifying changes in agricultural areas. The paper then expands on ...

Building Upon Common-Pool Resource Theory To Explore Success In Transitioning Water Management Institutions, Christina M. Hoffman

Dissertations & Theses in Natural Resources

Nebraska, like many regions around the world, is faced with the challenge of adapting to a new era in water management. Increasing demands for water resources, mounting concerns over threatened and endangered species, and obligations to abide by interstate water allocation agreements have motivated Nebraska to revisit traditional water management approaches. However, although Nebraska’s water management institutions have undergone much change, little research exists on the influence these changes have had on the ability of water institutions to successfully manage water allocations. This research (1) qualitatively explores the perspectives and experiences of stakeholders in the overappropriated region of the ...

Traditional Wild Protein Collection Techniques Of The Naso People: On The Verge Of Change, Caldwell Rohrbach

Independent Study Project (ISP) Collection

I studied the traditional wild protein collection techniques of the Naso people in the Syellick community Naso Territory, Bocas del Toro for 15 days during the end of November. The goal of this research was to record the various hunting techniques used by the Naso and determine whether those practices will disappear after the passing of this generation. I used informal and unstructured interviews as well as participant, objective, and passive observation (Master of Business Administration).

The Naso people complete at least one form of wild protein collection every day. The given technique is directly related to the weather on ...

Nutritional And Economic Analysis Of Small-Scale Agriculture In Imbaburra, Ecuador, Jake Erickson

All Graduate Theses and Dissertations

Nutritional and Economic Analysis of Small-Scale Agriculture in Imbabura, Ecuador Intervention projects in the developing world normally aim to satisfy either the nutritional needs of a group, or advancing the economic stability, but not both. One of the many issues that may arise by narrowly focusing and creating an aid program is that although a group may be fed, they are not equipped to mitigate risks that will arise after project completion and thus continue or revert back to a malnourished state. A bridge is required to join the economic and nutritional programs to create aid interventions that are sustainable ...

Overfishing: Economic Policies In Finite Resource Biological Pools, Abdullah Nasser

Undergraduate Economic Review

Common-property fishing is a classic example of the tragedy of the commons. Driven by competition, rational fishermen are forced to overfish to maintain marketplace viability. This shortsighted strategy will lead to the depletion of the common resource pool, and ultimately the destruction of the local fishing industry. In this paper, we present a dynamic differential system of a finite-resource fishing pool to model choices faced by average fishermen. We show that the situation mirrors a Prisonor’s Dilemma on the short- and long-terms, where overfishing is always the dominant Nash equilibrium strategy. Additionally, we use the model to analyze a ...

The Environmental And Economic Impact Of Removing Growth-Enhancing Technologies From U.S. Beef Production, Judith L. Capper, Dermot J. Hayes

Economics publications and other works

The objective of this study was to quantify the environmental and economic impact of withdrawing growth-enhancing technologies (GET) from the U.S. beef production system. A deterministic model based on the metabolism and nutrient requirements of the beef population was used to quantify resource inputs and waste outputs per 454 × 10⁶ kg of beef. Two production systems were compared: one using GET (steroid implants, in-feed ionophores, in-feed hormones, and beta-adrenergic agonists) where approved by FDA at current adoption rates and the other without GET use. Both systems were modeled using characteristic management practices, population dynamics, and production data from ...

Agricultural Land-Use Change And Local Context: The Shenandoah-Cumberland Valley Apple-Growing District In The Eastern United States, Joseph Paul Guttmann

Doctoral Dissertations

Across the United States, the rural-urban fringe continues to be a place of dynamic land-use change. One area that has experienced a change in its agricultural base is the Shenandoah-Cumberland Valley Fruit District of Pennsylvania, Maryland, West Virginia, and Virginia. Since 1982, apple acreage in the Fruit District has declined by nearly 50 percent. Using a mail survey and personal interviews, this dissertation investigates the factors behind the Fruit District’s 25-year decline in apple acreage, the reasons why this decline has not been spatially uniform across the Fruit District, and the ways that growers have adapted to ensure the ...

Primary Wood-Using Mills And Forest Resources: Interactions Between Wood Demand And Procurement Areas, Consuelo Brandeis

Doctoral Dissertations

It is a common belief that the presence of forest industry and associated wood demand will result in forest management of procurement areas. The following essays examined the relationship between mill demand and procurement areas by assessing the likelihood of forest management and the ability to predict future wood output. The first study investigates the likelihood of forest management given proximity to mills using a multivariate probit model, incorporating forest characteristics and primary wood-using mill information collected by the USDA Forest Service Forest Inventory and Analysis and the Timber Products Output (TPO) survey. The second essay explores the use of ...

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 ...

Evaluating The Contribution Of Infrastructure To U.S. Agri−Food Sector Output, Tingting Tong

Masters Theses

The effect of infrastructure investment or capital on private sector output and productivity has been widely discussed over the past two decades. However, only limited studies have focused on the contribution of infrastructure to the output of U.S. agricultural and food sector. Considering the importance of agriculture in U.S. economy and its strong dependence on infrastructure, two empirical analyses were made in this thesis to evaluate the output impact associated with infrastructure in agricultural and food sector in the United States. The first study examines the spillover effect of two major transportation modes, roads and rails, on agricultural ...

Feasibility And Impact Analysis Of An International Grain Reserve, Haijing Zhuang

Masters Theses

Recent price surges have caught the attention of the entire society, and have put food reserve policy back into the political spotlight. However, few studies have investigated the operation of a grain reserve on a global scale. Therefore, the objectives of my research are to model and compare alternative operational price bands of an international grain reserve, and determine the relative feasibility and impact of the alternative price bands.

A global economic model was modified by building the capability to analyze alternative price bands of an international grain reserve. The feasibility of alternative price-band scenarios were evaluated by comparing: 1 ...

Factors Influencing Precision Farming Technology Adoption Over Time In Southern U.S. Cotton Production, Pattarawan Watcharaanantapong

Masters Theses

This study analyzed factors of farm and farmer characteristics that influenced the timing of PF technology adoption using Trivariate Tobit models for three PF technologies. Data from the Cotton Incorporated Southern Precision Farming (PF) Survey conducted in February and March of 2009 for the 2008 crop year were analyzed for PF adoption by Southern U.S. Cotton Producers. The number of years a cotton farmer had used yield monitoring (YMR), remote sensing (RMS) and grid soil sampling (GSS) were the dependent variables and farm and farmer characteristics were the independent variables.

Results of Trivariate Tobit model for YMR suggested that ...
