Unaccountable corporate polluters profit short term at the expense of global economic sustainability. The purpose of the study was to determine if carbon dioxide (CO2) penalties on the airline emissions would result in financial statement disclosure and emission mitigation. Contributing to environmental accounting, the study was based in corporate social responsibility with a conceptual framework based on economically-centered CO2 studies. A random sample of 69 global airlines, taken from the International Air Transport Association (IATA) and the International Civil Aviation Organization (ICAO) memberships, was stratified between EU bound and non-EU bound airlines. The research questions explored (a) the frequency mean differences in disclosed CO2 costs between the strata based upon the European Union's environmental trading scheme (EU-ETS) and (b) whether international financial reporting standards (IFRS) influenced the financial statement reporting of CO2 emissions costs. Financial statement data were analyzed in a 3-year longitudinal, ex-post, quasi-experimental, repeated measures factorial ANOVA and ANCOVA, pretest-posttest control group design. The results showed significant CO2 disclosure differences between the experimental (EU bound) airlines and control group (non-EU) airlines and for those airlines with IFRS prepared statements. These results should convince accounting practitioners that the quantification and reporting of greenhouse gas pollution can become the catalyst for improved operations and commercial sustainability. Positive social change to mitigate anthropogenic pollution should result and should promote normative accounting practice to hold those responsible to a higher global accountability.

There has been little research conducted regarding the agricultural machinery market in China. However, current data suggest that this demand is dramatically increasing. This dissertation endeavors to generally define the current demand of the agricultural machinery market in China. There has been research conducted on multiple factors of the agricultural machinery market in China, such as land tenure rights, rural migration, government agricultural policies, and others. Through the use of limited quantitative data, market demand is analyzed and defined. By means of a qualitative case study of a successful multinational corporation, Deere & Co., how the demand is being met for agricultural machinery in China is also discussed. This case study also contributes to defining market demand for agricultural machinery in China. Through the use of this mixed-method research, key components of the Chinese agricultural machinery market are identified and analyzed. Challenges within this market are discussed, along with how Deere & Co.'s Chinese operations have dealt with these challenges. This corporation's experience in the Chinese market brings benefit to any company seeking to better understand the workings of the agricultural machinery market in China.

Ideas developed by regional economists have potential applications within the urban planning field. One potential application is toward conserving farmland, and within this thesis this topic is examined for the study area of Utah County, Utah. Using assessor data, a land value map is created and further used to develop a regional economic model and spatial models that were analyzed for patterns of land use change. Findings show that representing land value as continuous surface maps is a useful approach. The maps reveal that Utah County has densified as its population increased while farmland loss still occurred in agriculturally-important areas. Vulnerable areas were identified by examining the value of changed lands. Change mapping shows that macro-level variables affect local land values and subsequent development patterns. While limitations exist, the conclusion was drawn that this data is useful in connecting land value to location, examining change over time, and understanding how individuals’ priorities (as represented through property values) may conflict with (and potentially solve) collective goals.

The purpose of this research is to provide quantitative and limited qualitative analysis for the United States Intermountain West on the economic effectiveness of risk management alternatives in an agricultural operation. This research is not meant to be an exhaustive comparison of every potential combination of alternatives and risk scenarios. Instead, specific parameters such as farm size, crops grown, risk attitudes and risk management strategies are set to guide the research and offer a basis of comparison. This research evaluates several levels of coverage using Multiple Peril Crop Insurance, Crop Revenue Coverage Insurance, Adjusted Gross Revenue - Lite Insurance and a limited interaction of the futures market. Microsoft Excel and the add-in Simetar was used to perform the quantitative analysis. A set of spreadsheets were created to allow a variety of data to be easily input and manipulated. The values used in this research were based on the 2002 Census of Agriculture to create a "typical" farm considered in Box Elder County, Utah. The results generated were sorted and ranked according to four decision criteria in relation to the net income observed in each simulated scenario. These include: the probability that net income will exceed $0; a maxi-min; a maxi-max; and the maximum positive net income at a probability of occurrence of 0.5, resembling a Safety-First criterion. The later three decision criterion used correspond to risk attitudes that may be possessed by a producer: risk adverse, risk preferring or seeking, and risk neutral respectively. The quantitatively "best" observed results were then qualitatively compared to the next "best" result. In general the conclusion is made that some strategy is better than no strategy and the "best" risk management strategy is one compatible with the risk attitude of the producer and the parameters of the farm in consideration. There is no single strategy for all decision criterions that consistently outperforms all other strategies considered in this research.

For the last 46 years, the countries of the world have tried to reduce the number of chronically hungry people. Despite all the efforts, the numbers have barely budged from the over 850 million people who were chronically hungry in 1974 until the 2007-2009 food price crisis, when the numbers increased to over 1.02 billion. The blame for this situation has variously been put on bad governance, the lack of adequate market reforms, the market reforms that were imposed on developing nations, and globalization. Food, like other products in this globalized world, is allocated using the market system. One likely place to look for the cause of continuing hunger is at the assumptions that underlie the market system, in particular the assumption of non-coerciveness. This assumption asserts that the market transaction—in this case for food—is freely entered into by both the buyer and the seller and that either can refuse to enter into the transaction if it is not to their advantage. After looking at the traditional understanding of coerciveness in economics, this dissertation examines the logic system of economics concluding that the issue of non-coerciveness is a moral issue, and the argument of Frank Knight that the question of non-coerciveness is an issue of ethics. Using the work of Michael Keeley, this paper concludes that broadly accepted human rights is the best possible criterion for determining whether or not the aggregate food market is non-coercive. If the human right to food is abridged then it can be said that the aggregate food market is coercive and the assumption of non-coerciveness for the aggregate food market does not hold. With 1.02 billion people chronically hungry, 1/6 of humanity, it is clear that the right to food has been abridged and the aggregate food market is coercive. To overcome chronic hunger and enforce the right to food, governments, international agencies, and non-governmental organizations are going to have to supplement markets with non-market measures. The dissertation concludes with a number of recommendations for non-market measures that can be taken to ensure that all people enjoy the right to food.

This dissertation considers three topics under the themes of wetland restoration, urban sprawl, and recreation demand employing spatial data and analysis. A key question addressed in the first essay is how we can identify priority areas for wetlands restoration along the Louisiana coast under the Coastal Wetlands Planning, Protection, and Restoration Act by estimating amenity values received by nearby residents from hypothetical wetlands restoration projects. The second essay evaluates the effectiveness of alternative land-use policy variables for controlling development in a sprawling metropolitan area during two extreme market conditions. The third essay estimates the effect on consumer welfare from improved satisfaction of recreation information availability.

For several decades following its independence from Great Britain, Ghana’s policies continued to promote over-extraction of natural resources to the detriment of its economy and rural communities. Agricultural and forestry policy has gradually evolved to foster more sustainable and equitable practices, as in building partnerships with the private sector to fund infrastructure improvements. Policy has recently recognized the dire need to adopt agricultural practices and means of forest resource extraction that are compatible with ecological stewardship. However, many shortcomings are still apparent. Large logging operations completely disregard forestry regulations with impunity, whereas rural sustenance extractors are severely punished in the rare event that policy is actually enforced. Although the severe disadvantages that agricultural policies had imposed in the 1960s have been partially alleviated, much improvement is still needed. Recent agricultural policy has recognized the lack of funding available to invest in more efficient and higher-yielding agricultural practices, but partnerships with the actual lending institutions do not exist. The scarcity of crucial inputs, such as fertilizer and technical assistance remains a major problem in the agricultural sector, as the soils are becoming rapidly depleted, leading to declining crop yields and further encroachment on the 20 percent of forests remaining. Overly ambitious targets and unrealistic policies require more careful and detailed formulation so that Ghana’s resources can be managed effectively before famine sweeps the food-insecure country once more.

Karst regions are composed of soluble rock, often limestone, which leads to the formation of fissures, sinkholes and water flow conduits such as caves. Pollutants in karst waters tend to be quickly directed and concentrated into these subsurface conduits. As a result of this and other factors, water resources are especially sensitive to contamination and pollution in karst areas. Pollutant concentrations going into fluvial systems travelling through the subsurface in karst areas are often very similar to the concentrations arriving at outlets such as springs. Areas connected by karst conduit flows must be distinctly determined and special attention should be given to water quality impacts from land-use practices near conduit inputs. The climate which affects a certain karst area can also have different impacts on water resources considerations. For example, in the temperate climate of Kentucky precipitation is essentially even in distribution throughout the year. In contrast, southwest China is affected by a monsoon climate with high precipitation in the spring to summer and drier conditions in other seasons. In the wet season large storm pulses can effectively transport contaminants to water sources resulting in loads that can be unhealthy for frequent human consumption in drinking water. The dry seasons can be particularly severe in karst areas as water quickly drains to the subsurface, making water access a major hardship. The research for this study focused on the seasonal influences that the climate of southwest China poses for water quality, including differences in pesticide concentrations between agricultural and residential areas hydrologically linked by karst conduits. In late 2007 the fluvial connections in a simple karst system near Chongqing were confirmed using dye tracing techniques. Once these connections were established and the flow of the subterranean stream was assessed, the transport of agricultural runoff in the system was studied. Data loggers were used to record continuous data of the water conditions, including nitrate concentrations. The pesticides in the agricultural runoff entering and exiting the subterranean stream were quantified using ELISA methods. The concentrations were found to be within safe limits for drinking water. The hypothesis that there is a close relationship between concentrations of the pesticides glyphosate, chlorothalonil, and triazines in the input and the output of the system was supported by the results. When considering the hydrology and water chemistry data of the site, along with the water samples tested for pesticides, non-parametric statistical testing showed the correlations between these factors to be significant with p<0.01. The percent difference between the input and the output concentrations of glyphosate, chlorothalonil, and triazines were 31, 43, and 57% respectively. Taking into account the rapid and direct flows in this karst system, the concentrations of the pesticides found in the output were more similar to the input than would be expected in a surface stream. This suggests that there are fewer natural remediation effects reducing contamination in subsurface karst rivers of southwest China than in surface rivers. Therefore, these systems should be handled with extra attention to possible contamination of water resources. The research was conducted in the spring and summer of 2007-2008 and funded by the U.S. Agency for International Development.

The illegal bushmeat harvest has been identified as a reason for declining wildlife populations throughout much of Africa. For many years the trade was thought to exist primarily in Western Africa. The illegal use of bushmeat in Eastern Africa, including Kenya, went undocumented and unstudied. In 2004, the Born Free Foundation published a study which claimed illegal sale of wild game was substantial in butcheries throughout Nairobi, Kenya. In an effort to determine other markets of the commercial trade, the goal of this study was to analyze local restaurants in Voi, Kenya for illegal bushmeat sale. The town of Voi was selected due to recent published reports in the popular press, its proximity to Tsavo National Park, and its access to a major highway. Samples were collected and analyzed using mDNA sequencing analysis of the cytochrome B gene. None of the collected samples were identified as illegal game meat. The restaurants in Voi, Kenya were not a commercial outlet for illegal bushmeat trading in the local economy during the period of this study. The results from this study provide valuable baseline data which can be used in future research to help determine possible vectors of the bushmeat trade.

A major economic constraint in the Bahamas, and other small carbonates islands world-wide, is the lack of fresh water resources. To combat these socio-economic problems on San Salvador Island I sought to gain a more detailed understanding of the extent, behavior, and controls on the island’s fresh-water lens. DC electrical resistivity tomography and time-series geochemical data are used to study the fresh water lens at the Line Hole well field. Electrical Resistivity profiles are used to image the extent of fresh water resources. Time-series geochemical data provide information on the behavior of the fresh water resources as a function of time. The inversion models of the electrical resistivity profiles illustrate a fresh water lens less than 3 meters thick on average. The mixing zone is diffuse in nature, and substantially thicker than the fresh water lens. The geochemical results corroborate the fresh water lens dimensions predicted by the electrical resistivity model. In addition, mixed semi-diurnal and spring/neap tidal cycles are the primary control on the water level. Statistical analysis of specific conductance and temperature illustrate a positive and negative correlation with water level, respectively. Analysis of precipitation with respect to water level and geochemistry indicate low effective recharge rates during the period of study. The current state of the water resources at the Line Hole well field is strained. Despite moderate levels of freshening since the termination of pumping in December 2006; the system continues to be in a state of disequilibrium. The problem is compounded by abnormal thickening of the mixing zone due to communication of the well field with the ocean, and a limited volume of fresh water. In conclusion, the two techniques used in conjunction provide a non-invasive method of estimating fresh water resources in this type of setting. Conversely, the high RMS and L2 values for the electrical resistivity models and limited time-series data create a high level of uncertainty in the interpretation of results.
