It is assumed to yield specific benefits . increased food production decreased use of pesticides and herbicides and improved food quality. However after more than a decade of commercial experience in some countries outside Europe it seems apparent that several initial expectations could not be met for example the overall reduction in pesticide use. Unlike chemicals that degrade by time genetically modified organisms GMO as well as their decomposition products have the potential to proliferate and persist in the environment eventually without the possibility of removing them once they have been released. Thus concerns have been raised about potential adverse environmental impacts of the GMO and about potential implications on the coexistence between conventional and genetically modified production. This makes risk assessment as well as monitoring highly challenging tasks towards minimising the risk of adverse effects. Ecological agricultural and economic implications resulting from the cultivation of GMO at large spatial scales are currently discussed in science administration and in the context of agricultural practice. A challenging task in this context is how to assess large-scale and long-term effects of GMO release in the approval procedure in the planning of coexistence measures and in post-market monitoring regarding environmental as well as food monitoring. The international conference Implications of GM Crop Cultivation at Large Spatial Scales GMLS was held at the University of Bremen first in April 2008. In March 2010 a second edition of the conference GMLS II was .
