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 …

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 …

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.

Coping With Dr-Cafta: Assessing The Impact Of The Agreement And Designing Adjustment Programs For Sensitive Agriculture In Honduras, Alvaro Durand-Morat May 2009

Coping With Dr-Cafta: Assessing The Impact Of The Agreement And Designing Adjustment Programs For Sensitive Agriculture In Honduras, Alvaro Durand-Morat

Graduate Theses and Dissertations

Honduras has for almost two decades embraced economic integration as a way to achieve sustained economic growth. The DR-CAFTA agreement signed in 2004 represents another step towards economic openness. The agreement generated a heated debate about the benefits and costs to the Honduran economy. Previous assessments suggest that Honduras will have a marginal aggregate benefit from DR-CAFTA. The findings from this study suggest that the agreement might actually yield a marginal loss vis-à-vis the counterfactual. Previous studies also stress the potential for large losses resulting from the agreement, particularly for some traditional and sensitive agricultural sectors. The findings from this …
