The co-existence between GM and non GM oilseed rape: identification of critical points in two European contrasted regions
The implementation of the European regulation on co-existence between GM (genetically modified) and non GM crops is critical in the case of oilseed rape, Admixture can occur in the field, due to cross pollination and volunteers, and after harvest, due to grain transport and storage. We started from the hypothesis that such problems depended on the local context, including farm types, landscape, cropping systems, and the infrastructure for storage and transport of seed. In that case, co-existence should require adapted solutions. The methodology to test this hypothesis included three steps: (1) two contrasted European regions were described via existing databases and surveys on farms; (2) for each region, a gene flow simulator predicted the admixture between GM and non GM oilseed rape in real landscapes, in the case of GM introduction: the simulator quantifies spatial and temporal gene flow via pollen dispersal and seed persistence as a function of cropping systems; (3) results were discussed by local actors (farmers, private contractors, cooperatives, grain merchants) in order to identify the critical points. This methodology allowed us to analyse how the constraints for the management of co-existence varied between each region but also within each of them. The results will be used in further studies on the elaboration of scenarios for co-existence.
