This book addresses the issues and methods involved in governing risks posed by genetically modified (GM) agriculture. It examines the evolution of policies intended to ensure the safety of GM crops and food products in the United States and Europe, and the regulatory approaches and other social controls employed to protect human health, the environment, conventional farming and foods, and the interests and rights of consumers. Discussion encompasses the cultural, political, and economic forces that shape the design and application of the methods of risk governance, as well as other contextual features such as the influence of multinational companies seeking acceptance of their GM ventures. This discussion also examines the influence of the dynamic public discourse fostered by progressive concepts of risk governance and the approaches taken to meet its demands for transparency, public participation, and appropriate consideration of public perceptions and values despite conflicting views of experts.
