As society begins to recognize its impact on ecological systems, the belief that modern political institutions can offer a sense of control and certainty, as well as protect the health of its citizens, is increasingly questioned. In an era of uncertainty, faith in science and technology to alleviate industrial impacts on the environment is often embraced by policymakers yet questioned by the public who see the authoritative role of the sciences in the political sphere as contributing to global risk. The development of biotechnology, specifically genetically modified food, places an anthropocentric focus on resolving and/or adapting to environmental degradation, further reflecting an adherence to the dominant social paradigm to address the consequences of modernization. In order to explicate the dualism of human/nature relations inherent in biotechnology, the focus of this research provides an exploration into two competing paradigms of genetically modified organism (GMO) regulatory policy: scientific rationality and social rationality. Through a careful examination of the evolution of GMO regulation in the United States and the European Union, the precarious relationships between science and politics and progress and precaution reveal an actual convergence instead of divergence between these two actors in the international system. Although existing literature proclaims a division between the values and ethics of U.S. and EU environmental policy, the end result of this comparison in GMO regulation illustrates that in both the risk assessment and precautionary approaches, nature is still viewed as an instrument for advancing enclosure of the commons.

The present study analyzes the economic impact of the introduction of Genetically Modified Organisms (GMOs) in Uruguay's agriculture. Using a partial equilibrium framework the impacts of transgenic varieties are simulated for two crops, rice and potatoes, in small open and closed economies respectively. The model accounts for the presence of market imperfections created by the monopolistic behavior of the genes' patent owner. The change in economic surplus generated after the adoption of the new technology is projected to be positive, although the seed markup charged by the monopolist reduces the surplus compared to a perfectly competitive market. Total deadweight losses and domestic losses are found to increase with the seed premium, as additional monopolist profits are extracted out of the country. Adoption decreases with the seed premium, further reducing the domestic consumer and producer surplus. The results of the study suggest an active role for national technology policies and for the agricultural R&D system in Uruguay to generate conditions that attract the technology's owner to a small market while at the same time reducing the potential losses that monopoly power creates . / Master of Science

Using a critical discourse analysis (CDA), this thesis examines how risks and food security, in relation to Genetically Modified (GM) foods, are constructed within the media context. The project analyzes news articles that appeared in two Canadian newspapers, The Globe and Mail and The Toronto Star, and two British newspapers, The London Times and the Guardian, during three particular time periods between 1997 and 2005. I evaluate whether or not the selected articles contribute to the public’s understanding of science, and how journalism constructs risk and uncertainty. I also evaluate the use of expert knowledge by journalists. Using the theory of Risk Society, as proposed by sociologist Ulrich Beck, the project explores the connections between political, social, and economic issues connected to globalization. This thesis concludes that journalism in both Canada and Britain does not appear to adequately inform their citizens on matters of food security and the risks of GMOs.

Legal Regulation of the Use of Genetically Modified Organisms ABSTRACT The use of genetically modified organisms on a global scale is on the rise which requires their efficient and consistent regulation. The main goal of the thesis is to provide a comprehensive overview of the legal regulation of genetically modified organisms and their use on several levels. After an introduction to the topic, the thesis deals with the key international documents and then moves on to examining different approaches on the topic and exploring regulation in the United States and in the European Union with a connection the legislation in Czech Republic. In addition, four annexes are included at the end of the thesis for a better illustration of the current use of genetically modified organisms in the world.

The 18 September 2000 disclosure that StarLink corn, a genetically engineered variety not approved for human consumption, had been detected in food was a seminal event in agricultural biotechnology. This thesis presents a comprehensive case study of the StarLink incident (part one), reviews the StarLink situation in terms of crisis management theory (part two) and develops crisis management theory using the StarLink incident as an example of a crisis (part three). Part one provides background information, then a meticulous day-by-day account of StarLink-related events. Part two presents a detailed overview of crisis management theory, then examines the StarLink situation in terms of pre-crisis (warning signals, preconditions for a crisis, crisis trigger), crisis (how Aventis, the biotechnology provider, managed the crisis and opinions concerning crisis handling) and post-crisis (lessons learned). Part three develops crisis management theory using the StarLink situation as an example of a crisis. It evaluates whether the StarLink incident possessed characteristics predicted for modern crises and suggests other factors which may become more prevalent and significant in future crises. The StarLink incident delivers certain practical lessons for managers, regulators and others and demonstrates a number of characteristics of modern crises.
