This book analyses the conflict over the release of transgenic soybean in Brazil based on a narrative analysis of political conflict. At the end of the 1990s, the commercial release of Roundup Ready (RR) soybean triggered a heated debate over the introduction of genetically modified organisms (GMOs) in Brazilian agriculture, which developed into an open political conflict opposing pro- and anti-GMOs groups in Brazilian society. This volume examines some of the structuring axes of this conflict by applying a narrative analysis of political conflict. In this approach, politics is perceived as a process of interpretive conflict in which participants in the political game seek to establish the lines that delimit the very definition of public issues under debate. The issue of GMOs is understood, from this perspective, as a public controversy whose dynamics are shaped by the discourses that emerge from the dispute itself. To analyze these controversies, the book focuses on threeaxes of narrative analyses: the conflict over distributives issues associated with the commercial release of RR soy; the conflict over scientific uncertainty associated with the environmental risks of GMOs; and the conflict over labeling policies. Transgenics in Dispute: Political Conflicts in the Commercial Liberation of GMOs in Brazil will be of interest to both social and environmental scientists concerned with the risks produced by the newest technologies that mediate our relationship with the environment and with the public debate that their use tends to provoke. This book is a translation of the original Portuguese edition Transgnicos em disputa: Os conflitos polticos na liberao comercial dos OGMs no Brasil by Cristiano Luis Lenzi, published in Brazil by Appris Editora in 2020. The translation was done with the help of artificial intelligence (machine translation by the service DeepL.com). The author has subsequently revised the text further in an endeavour to refine the work stylistically. Springer Nature works continuously to further the development of tools for the production of books and on the related technologies to support the authors.
