In this study, our goal is to identify and explain the underlying factors that drive regional adoption of Bt maize MON810 in Germany. Since regional differences cannot be explained by the occurrence of the target pest alone, we assume that under the given regulatory framework for genetically modified (GM) crop production in Germany, farm structures as well as the sociopolitical environment have also influenced regional adoption rates during the past years. Following a description of the relevant legal and economic framework in Germany, we develop theoretical hypotheses for regional variation in Bt maize adoption and test them econometrically with unique data at the federal state (Laender) and county (Landkreis) level. According to our analysis at the federal state level, the maize acreage per farm is the main driver of Bt maize adoption. In addition, there are signs that public opposition to GM cultivation as measured by membership in the German Friends of the Earth association significantly dampens GM cultivation. At the level of Brandenburg counties, the regional infestation frequency of the European Corn Borer, the target pest of Bt-Maize, is the major determinant of adoption. Although Bt maize is a scale-neutral technology for controlling damages caused by the Corn Borer, additional fixed costs due to regulation make the technology scale dependent.

Genome-edited crops are on the verge of being placed on the market and their agricultural and food products will thus be internationally traded soon. National regulations, however, diverge regarding the classification of genome-edited crops. Major countries such as the US and Brazil do not specifically regulate genome-edited crops, while in the European Union, they fall under GMO legislation, according to the European Court of Justice (ECJ). As it is in some cases impossible to analytically distinguish between products from genome-edited plants and those from non-genome-edited plants, EU importers may fear the risk of violating EU legislation. They may choose not to import any agricultural and food products based on crops for which genome-edited varieties are available. Therefore, crop products of which the EU is currently a net importer would become more expensive in the EU, and production would intensify. Furthermore, an intense substitution of products covered and not covered by genome editing would occur in consumption, production, and trade. We analyzed the effects of such a cease of EU imports for cereals and soy in the EU agricultural sector with the comparative static agricultural sector equilibrium model CAPRI. Our results indicate dramatic effects on agricultural and food prices as well as on farm income. The intensification of EU agriculture may result in negative net environmental effects in the EU as well as in an increase in global greenhouse gas (GHG) emissions. This suggests that trade effects should be considered when developing domestic regulation for genome-edited crops.
Genome editing (GE) is gaining increasing importance in plant breeding, since it provides opportunities to develop improved crops with high precision and speed. However, little is known about the socioeconomic impact of genome editing on agricultural value chains. This qualitative study analyzes how genome-edited crops could affect agriculture value chains. Based on the hypothetical case of producing and processing fungal-resistant and coeliac-safe wheat in Germany, we conducted semi-structured, in-depth interviews with associations and companies operating in the value chains of wheat. A value chain analysis and qualitative content analysis were combined to assess the costs and benefits of the crops studied along the value chains of wheat. The results show that the use of fungal-resistant and coeliac-safe wheat can provide benefits at each step of the value chains. Fungal-resistant wheat benefits actors by reducing the problems and costs resulting from fungal-diseases and mycotoxins. Coeliac-safe wheat benefits actors by producing high value-added products, which can be safely consumed by patients suffering from coeliac disease. However, the results also show that low acceptance of GE by society and food retailers poses a significant barrier for the use of genome-edited crops in agricultural value chains.
