The Challenge of Scientific Uncertainty and Disunity in Risk Assessment and Management of GM Crops

摘要

The controversy over commercial releases of genetically modified (GM) crops demonstrates that there is a need for new approaches that are more broadly based, transparent and able to acknowledge the uncertainties involved. This article investigates whether new forms of knowledge productionas prescribed in the concept of post-normal science can improve risk governance of GM crops. The GM science review carried out in the UK in 2003 serves as a case study and the focus is on how scientific uncertainty and public concern was taken into account. Some recommendations are advanced for assessing scientific uncertainty, for accommodating scientific disputes and for integrating stakeholders' interests and perspectives in relations to GM crops.
