Co-existence: 25 metres sufficient
Wageningen – A Dutch analysis has concluded that the country’s forseen GMO regulations for coexistance are efficient. A preliminary analysis of the two-year program carried out by the University of Wageningen and the Institute for Food Safety has shown that a 25-metre isolation distance is sufficient to avoid labeling obligations for farmers with conventional or organic maize in the neighbourhood of GM maize cultivations. The researchers found that the distance led to an average content of 0.01% to 0.3% of insect-resistant Bt-maize (MON810) in the non-GM crops. At a distance of 250 metres, the average outcrossing rate lays between 0% and 0.003%. Accordingly, all measured rates remained far below the EU labeling threshold of 0.9%.Another part of the Dutch coexistance agreement was a risk analysis with an evaluation of potential economical damages to conventional or organic farmers caused by the cultivation of GM crops in the Netherlands. This study was conducted by the Institute for Risk Management in Agriculture at the University of Wageningen and comprises damage scenarios for maize, potatoes and sugar beet. According to the scientists, the analysis reveals that the value for the average direct economic damage as a consequence of cross breeding is almost zero.
