Food Sovereignty In The United States: Supporting Local And Regional Food Systems, Allison Condra Dec 2012

Food Sovereignty In The United States: Supporting Local And Regional Food Systems, Allison Condra

Journal of Food Law & Policy

Today, perhaps more than ever, an increasing portion of U.S. society is paying attention to and asking questions about our food and agricultural system. We are recognizing the immense consequences of the agricultural "efficiencies" we valued and wrote into our policies in the seventies-for example, growing corn "fence row to fence row" and the ease of microwaved meals and prepackaged foods. 3 The increasingly global nature of our food system and its consequences are becoming more apparent. Food safety concerns-prompted by a growing number of foodborne illness outbreaks and the government's response in the 2009 Food Safety Modernization Act-loom large …

The Impact Of Bovine Spongiform Encephalopathy (Bse) On World Protein Supply, Jarrod Kersey Dec 2012

The Impact Of Bovine Spongiform Encephalopathy (Bse) On World Protein Supply, Jarrod Kersey

Graduate Theses and Dissertations

As world population, per capita income and urbanization increase, consumption of meat, poultry, milk and eggs will continue to rise to meet the needs of approximately nine billion people in 2050. Global beef, pig and chicken production and per capita consumption increased between 2000 and 2010, with growth in broiler production and consumption outpacing both beef and swine. The increased production and consumption requires readily available feed ingredients in regions where animal production is rapidly developing. Animal-based protein feed ingredients are often difficult to move from country to country due to real or perceived risk of animal disease. Zoosanitary standards …

The Evolution Of Natural Plant Communities Through Crop Migration And Crop-To-Weed Gene Flow, Meredith G. Schafer Aug 2012

The Evolution Of Natural Plant Communities Through Crop Migration And Crop-To-Weed Gene Flow, Meredith G. Schafer

Graduate Theses and Dissertations

With the rising demand for food and biofuels, the efficiency of crop production has become vital to assuring food security. Genetically engineered (GE) crop varieties are broadly thought to be a solution for improving the efficiency of crop production, but concerns regarding their release have heightened as more discoveries have focused on the influence of genetically engineered crops on native and weedy plant species. Risk assessment of GE crop varieties focuses on two main areas: feralization of crop systems and crop-weed hybridization. Risks include naturalization, transgene introgression, and the formation of novel genotypes in natural systems. In this study, roadside …

Food Environment And Childhood Obesity, Yucong Jiao Aug 2012

Food Environment And Childhood Obesity, Yucong Jiao

Graduate Theses and Dissertations

This thesis examines whether children's food environment, especially food stores that have fresh produce, affects obesity prevalence among elementary school children in the state of Arkansas. Misclassified food outlet types in the Dun and Bradstreet commercial data set were first corrected and then food environment measures were computed and aggregated to geographic regions corresponding to school attendance areas. After applying classical panel estimation, it was found that the fixed effects model fit the data best. Results indicate that an additional supermarket within a one-mile radial of the census neighborhood block center will bring down childhood obesity prevalence by 0.58 percent, …

Impact Of Hybrid Rice On Food Security: A Spatial Equilibrium Analysis Of Global Adoption And Diffusion Of Hybrid Rice Varieties, Till Ludwig Aug 2012

Impact Of Hybrid Rice On Food Security: A Spatial Equilibrium Analysis Of Global Adoption And Diffusion Of Hybrid Rice Varieties, Till Ludwig

Graduate Theses and Dissertations

Rice is the staple crop for most consumers in Asia. More than half of the global population depends on rice. However, scarce resources for agricultural production and unfavorable conditions will make it hard to meet future demand in rice and threaten future food security. Hybrid rice technology is a method to increase the productivity of resources needed for rice production. Current developments show not only yield improvements in comparison to existing conventional and hybrid varieties, but also fuel hopes for new abiotic and biotic stress tolerance. The objective of this study is to determine what impact hybrid rice varieties can …

Toward A Constructive Engagement: Agricultural Biotechnology As A Public Health Incentive In Less-Developed Countries, Chidi Oguamanam Dec 2011

Toward A Constructive Engagement: Agricultural Biotechnology As A Public Health Incentive In Less-Developed Countries, Chidi Oguamanam

Journal of Food Law & Policy

Discourses on global public health crises, especially as they impact the less-developed world, focus mostly on the issue of access to life-saving drugs for needy populations. Also, they implicate the misalignment of global pharmaceutical research and development (R&D) agenda with the health needs of the poor. Equally attracting significant attention is the role of intellectual property in driving up the cost of drugs and exacerbating the drug access freeze to needy populations. More often, the conceptual strings of these discussions are woven around a complex interaction of themes, including those of globalization, the development narrative, and strategic changes in international …

The History And Future Of Genetically Modified Crops: Frankenfoods, Superweeds, And The Developing World, Brooke Glass-O'Shea May 2011

The History And Future Of Genetically Modified Crops: Frankenfoods, Superweeds, And The Developing World, Brooke Glass-O'Shea

Journal of Food Law & Policy

In a 1992 letter to the New York Times, a man named Paul Lewis referred to genetically modified (GM) crops as "Frankenfood," and wryly suggested it might be "time to gather the villagers, light some torches and head to the castle." Little did Lewis know that his neologism would become the rallying cry for activists around the world protesting the dangers of genetic engineering. The environmental activist group Greenpeace made great use of the "Frankenfood" epithet in their anti-GM campaigns of the 1990s, though they have since backed away from the word and the hardline stance it represents. But genetically …

Comparison Of Growing Media For Container Grown Plants, Paul Harris, David Longer, Derrick Oosterhuis, Dimitra Loka Jan 2011

Comparison Of Growing Media For Container Grown Plants, Paul Harris, David Longer, Derrick Oosterhuis, Dimitra Loka

Discovery, The Student Journal of Dale Bumpers College of Agricultural, Food and Life Sciences

Greenhouse and growth chamber experiments are conducted worldwide in efforts to produce solutions that would increase yields of agronomic crops. However, the results of those experiments vary due to the many growth media being used. An experiment was conducted in the fall of 2010 to identify a broadly acceptable growth media that would produce uniform stands and optimum results in greenhouse and growth chamber settings. A total of six growth media were tested on cotton (Gossypium hirsutum) at the Arkansas Agricutural Research and Extension Center’s Altheimer Lab in Fayetteville. The plants grown in each medium were harvested six weeks after …

Molecular And Phenotypic Comparisons Of Salt Effects On Soybean Cultivars With Differential Chloride Uptake Capacities, Sharon Faye Holifield, Fernando Ledesma Rodriguez, Richard D. Cartwright, Pengyin Chen, Kenneth Korth Jan 2011

Molecular And Phenotypic Comparisons Of Salt Effects On Soybean Cultivars With Differential Chloride Uptake Capacities, Sharon Faye Holifield, Fernando Ledesma Rodriguez, Richard D. Cartwright, Pengyin Chen, Kenneth Korth

Discovery, The Student Journal of Dale Bumpers College of Agricultural, Food and Life Sciences

Genetic manipulation of crop plants, through breeding or transgenic approaches, for enhanced tolerance to abiotic stress holds great promise for improving yields and promoting new methods for sustainable agriculture. This study examines the potential role that genes of the soybean, Glycine max L., encoding elongation factor-1 alpha (EF-1α) and glyoxalase I (GlxI) might play in response to salt stress. Previous reports have suggested a possible function for both GlxI and EF-1α in conferring enhanced salt tolerance in other plant species. In addition to other possible mechanisms, salt tolerance in soybeans can be regulated by plant uptake and transport of chloride …

Food Justice As Crime Prevention, Avi Brisman May 2009

Food Justice As Crime Prevention, Avi Brisman

Journal of Food Law & Policy

In December 2008, Governor David Paterson (D-NY) proposed an 18 percent tax on nondiet sodas and fruit drinks containing less than 70 percent natural fruit juice. While the tax was part of a broader budget proposal designed to address New York State's fiscal crisis - a plan that that included new taxes and tax hikes on 137 items and services' - state officials promoted the "obesity tax," as the soft drink levy came to be called, as a public health measure.
