EU study finds positive cost/benefit outcome for GM crops
An EU-funded study of worldwide data on genetically modified crops concludes that their adoption “leads on average to higher economic performance”. Compared with conventional crops, GM crops can result in yield increases and reductions in pesticide costs, but seed costs are “usually substantially” higher. However, the type and magnitude of benefits are “very heterogeneous” among countries and regions, particularly due to differences in pest pressure and pest management practices, the study concludes. Countries with poor pest management practices benefited most from a reduction in yield losses, while other countries benefited from cost reductions. The study focused on insect-resistant Bt cotton and maize.
