Abstract

In May 2000 DG AGRI requested a study on agronomic and economic aspects of co-existence of GM, conventional and organic crops in European agriculture from the Joint Research Centre. The study was initiated as a pan-JRC operation and with external expertise mostly channelled via the European Science and Technology Observatory (ESTO).

This synthesis report presents the results obtained and is based on six studies performed by different institutes:
- Analysis of potential risks of contamination;
- Analysis of necessary adjustments of farming practices;
- Overview of existing segregation methods;
- Analysis of financial losses in case of contamination;
- Farm level monitoring of GMO content in non-GM crops;
- Review of GMO detection and quantification techniques.

If commercial production of genetically modified (GM) crops increase their share in European agriculture, the question arises as to whether adventitious presence of GM crops in organic or in conventional crops at farm and at regional level could significantly increase if current farming practices are maintained. For three different crops in specific EU farm type settings, levels of adventitious presence of GM crops are estimated and changes of farming practices to meet defined thresholds are identified and assessed. This is done with the help of computer models as well as expert scientific opinion. Costs of relevant changes of farming practices, of introducing and running a monitoring system and of potential insurance costs are also estimated.
