Abstract

Introduction

The counties of Vechta and Cloppenburg (Lower Saxony, Germany) are located in a highly intensified agricultural environment with one of the highest shares of animal production and maize cultivation in Germany. Compared with Eastern Germany or other intensively cultivated regions the average field size is rather small. If genetically modified (GM) maiz would be grown in this agrarian environment, it would be very important to anticipate the efficiency of segregation measures to prevent gene flow from GM to conventional fields. In Germany, there is a segregation distance of 150 m implemented between GM maize and conventional maize. To organic fields, a distance of 300 m has to be kept (GenTPfIEV 008). When the GM impurities in conventional crop go beyond 0.9%, the conventional harvest must be labelled and marketed as containing GMO (EU 2003). Those regions with a considerable hogh rate of maize cultivation and relatively small field sizes would be particularly relevant for coexistence feasibility estimates (Ernsing 2012).
