%X Definition of the problem:   Most of the farmers in Switzerland won’t apply GMO farming. Their organisations support a five-year ban for the marketing of transgenic plants. However, in Switzerland there is no political discussion on co-existence as in the European community and their member states.   Project aims including target group:  In this study, the spatial aspects of coexistence of transgenic, conventional and organic farming in Switzerland are investigated.   Special attention is be devoted to neighbouring producers all along the national boundary.   Methodology:  4 case studies in Switzerland, GIS-Analyses of available data, Literature research  Results, conclusion, state of the art:  In this study, the spatial aspects of coexistence of transgenic, conventional and organic farming in Switzerland are investigated. It shows that there are only 28 communities of 2848 where all farmers are bound by different labels to produce GMO-free. Most of these communities are situated in high altitude regions.   In contrast, in arable regions of Switzerland, few farmers produce organic crops. In most of the communities in Switzerland, the simultaneous production with and without transgenic plants will be a huge problem because:  - small scaled agriculture  - System for information flow is lacking  - high number of neighbours  Special attention must be devoted to neighbouring producers all along the national boundary.

%X The debate about co-existence usually focuses on the situation of neighbouring farms. Organic producers take the position that co-existence affects the whole supply chain. Therefore, this paper compares the maize grain supply chains in Switzerland and Spain in order to identify which factors influence the segregation of genetically modified (GM) maize from non-GM maize, and discusses how organic production copes with the challenge of GM maize. Considerable differences exist between Spain and Switzerland with regard to grain maize as a component of animal feed. In Spain, where GM maize is grown, it is the feed industry that defines standards in the supply chains. Since the trading co-operatives are unable to supply GM-free maize, independent and separate infrastructures have been developed for a GM-free maize supply (e.g. for maize starch). In Switzerland, the retailers define quality standards for suppliers, and these standards exclude the use of GM plants for feed. Therefore, the feed industry has to segregate GM from non-GM feed.
