An international initiative is developing a scientifically rigorous approach to evaluate the potential risks to nontarget arthropods (NTAs) posed by insect-resistant, genetically modified (IRGM) crops. It adapts the tiered approach to risk assessment that is used internationally within regulatory toxicology and environmental sciences. The approach focuses(More)
Measures blocking hybridization would prevent or reduce biotic or environmental change caused by gene flow from genetically modified (GM) crops to wild relatives. The efficacy of any such measure depends on hybrid numbers within the legislative region over the life-span of the GM cultivar. We present a national assessment of hybridization between rapeseed(More)
Genetically modified (GM) maize MON810 expresses a Cry1Ab insecticidal protein, derived from Bacillus thuringiensis (Bt), toxic to lepidopteran target pests such as Ostrinia nubilalis. An environmental risk to non-target Lepidoptera from this GM crop is exposure to harmful amounts of Bt-containing pollen deposited on host plants in or near MON810 fields. An(More)
Cultivation of genetically modified crops is presently based largely on four crops containing few transgenes and grown in four countries. This will soon change and pose new challenges for risk assessment. A more structured approach that is as generic as possible is advocated to study consequences of gene flow. Hazards should be precisely defined and(More)

A series of rotation experiments at five sites over four years has explored the environmental and agronomic implications of growing herbicide tolerant oilseed rape and sugar beet. This paper reports on the population dynamics of volunteer rape (Brassica napus). The experiments compared four winter oilseed rape (WOSR) cultivars: a conventional cultivar(More)
General Surveillance has been established to observe unanticipated adverse effects and to then trigger action in response to these observations. The first response will be to determine levels of harm and causes of the adverse effect. A possible cause of such an effect could be that farmers are cultivating combinations or sequences of GM crops in a manner(More)
The European Food Safety Authority (EFSA) is requested to assess the scientific quality of Post Market Environmental Monitoring (PMEM) plans submitted with each application for deliberate release of genetically modified (GM) plants according to part C of EU Directive 2001/18/EC and according to EU Regulation 1829/2003. PMEM aims at identifying unanticipated(More)
The scientific Panel of the European Food Safety Authority (EFSA) on genetically modified organisms (GMOs) developed guidelines for the environmental risk assessment of genetically modified (GM) animals that provide specific recommendations for GM fish, GM insects, GM mammals and GM birds. The guidelines advocate that the environmental risk assessment of GM(More)
People have a stake in conservation and environmental management both for their own interests and the sake of the environment itself. Environmental decision-making has changed somewhat in recent decades to account for unintentional impacts on human wellbeing. The involvement of stakeholders in environmental projects has been recognised as critical for(More)
