· Generally, coexistence would only be possible with massive changes in farming practices, especially for conventional farmers; it would also require co-operation between farmers in a region and the willingness of all farmers concerned to participate in such co-operation; it is not clear who would implement these changes, who would be responsible for controlling their correct implementation, who would shoulder their costs.

· Seed and crop purity from GE at a detection level of 0.1 percent would be virtually impossible in most cases, i.e. all products and seeds of oilseed rape and maize would be contaminated with GE to a certain extent.

The study, based on a combination of computer modelling and expert opinion, analysed the consequences of an increase in the share of GE crops. It focused on the three crops of which GE varieties are currently available: oilseed rape for seed production, maize for feed production and potatoes for consumption. The study covered several farm types, both organic and conventional farming. It also considered three different threshold levels for genetic contamination: 0.1 percent (analytical detection level) for all the three crops, 0.3 percent for oilseed rape and 1 percent for maize and potatoes.
