Research paper thumbnail of Economic Effects of Co-Existence Measures in Maize Crop and Seed Production - a Case Study of France

The results are based on simulations of agronomic measures and corresponding cost calculations for specific measures and landscape simulations. In maize grain production levels of adventitious presence below 0.9 % can be achieved without any co-operation between farmers in neighbouring clusters. In case fields are located in the same cluster, additional measures have to be taken with very differing cost effects depending on the specific characteristic of the measure. Additional measures should also be taken (either by the seed company or by the commercial GM grower) for ensuring co-existence between commercial GM fields and non-GM seed production clusters, while current practices would be sufficient for ensuring ...

The European GMO Socio-Economics Bureau1 (ESEB), composed of representatives of EU Member States, Norway and the European Commission2, has compiled topics, indicators, methodological guidelines and potential data sources to carry out analyses of these socio-economic effects into a Reference Document entitled: "Framework for the socio-economic analysis of the cultivation of genetically modified crops" (Kathage et al., 2015). This paper describes the development and the findings of the Reference Document. The Reference Document provides a framework that is applicable to any GM crop that has been or might be grown in EU Member States. Almost 100 indicators, which range from farm adoption rates to consumer surplus, have been identified by the ESEB. The Reference D...

The 2004 reform of the EU cotton policy severely affected the profitability of the crop. In this article we analyze how the introduction of genetically modified (GM), insect-resistant cotton varieties (Bt cotton) might help EU cotton farmers to increase profitability and therefore face the cotton policy reform. We first study farmers’ attitudes toward adoption of Bt cotton varieties through a survey conducted in Andalusia (Southern Spain). The results show a positive attitude of Andalusian cotton farmers toward the Bt cotton varieties. Second, we perform an ex-ante analysis of the effects of introducing Bt cotton in Andalusia. Finally, we integrate the analysis of the effects of Bt cotton with the analysis of the EU cotton reform. Our results show that despite the significant economic benefits of Bt cotton, the current policy reform is likely to jeopardize the profitability of cotton production in the EU."

Research paper thumbnail of Consequences of a coexistence policy on the adoption of GMHT crops in the European Union

A set of potential drivers including the implementation of coexistence measures by farmers, farmers' own motivational factors (e.g. economic, environmental and technical factors) and perceived social pressure to accept or reject adoption may influence European Union farmers' willingness to adopt GMHT oilseed rape and GMHT maize. The analysis includes economic and sociological factors. Results show that coexistence measures may hamper GMHT adoption in the EU.

Como paso previo a la medición de los posibles impactos, el presente trabajo tiene como objetivo la definición de escenarios combinados de ambas políticas. Los escenarios son afirmaciones sobre posibles futuros. No obstante, no son predicciones sobre lo que acontecerá. Son afirmaciones de lo que es posible, de prospecciones más que de predicciones sobre el futuro. Responden a preguntas con la forma "que sucedería si...". Después de construir unos escenarios, primero de política agrícola y después de política de aguas, este trabajo concluye proponiendo cuatro escenarios integrados los cuales pueden ser usados para medir la respuesta del sector ante las fuerzas del cambio. 2.

The term coexistence refers to the ability of farmers to choose between conventional, organic or GM-based crop production, in compliance with the relevant EU legislation on labelling and/or purity standards. EU regulations have introduced a 0.9% labelling threshold for the adventitious presence of GM material in non-GM products. Since agriculture does not take place in a closed environment, suitable technical and organisational measures during cultivation, harvest, transport and storage may be necessary to ensure coexistence. Coexistence measures should make it possible for farmers growing non-GM crops to keep the adventitious presence of GM material in their harvest below the labelling thresholds established by Community law.

The European GMO Socio-Economics Bureau (ESEB) has compiled topics, indicators, methodological guidelines and potential data sources to carry out analyses of these socio-economic effects. This document provides a framework applicable to any GM crop that has been or might be grown in EU Member States. Almost 100 indicators, which range from farm adoption rates to consumer surplus, have been identified by the ESEB Technical Working Group composed of representatives of Member States and with assistance from the European Commission's Joint Research Centre. Evidence of impacts in the EU already exists for some crop/trait combinations both ex post and ex ante but for most topics it is very limited. Methodologies have been developed by the scientific community for many of the topics and indicators ...

Since 2009, the European Commission's Joint Research Centre (JRC) analyses the economic impact of GHG mitigation policy options for EU agriculture. However, the lack of precise, integrated and harmonised data on the current and potential uptake, cost-effectiveness and GHG emissions reduction potential of technological (i.e. technical and management based) mitigation options hampers the analysis of the economic impacts of GHG mitigation in agriculture. Against this background, the JRC organised a workshop in Seville on 14th June 2016 which gathered European Commission staff and experts from diverse international institutions aiming to: i) identify current activities conducted by research institutes on the building of datasets for GHG mitigation technologies and t...
