|Abstract:||This letter shows that unnecessary large isolation distances may restrict farmers' freedom of choice to cultivate GM varieties given the particularities of European landscapes. For the first time we perform a statistical meta-analyses of over 1000 observations on maize gene flow in Europe. Taking into account the results obtained by several statistical approaches, we conclude that separation distances of 20-30 m are enough to keep out-crossing below legal thresholds (0.9 % in the EU). We conclude that mandatory distances established by some European countries (up to 800 m) may be disproportionate to the desired policy objective.|
