In light of the recently developed European Union (EU) Biofuels Strategy, the literature is reviewed to examine (a) the coherency of biofuel production with the EU nonindustrial vision of agriculture, and (b) given its insufficient land base, the implications of a proposed bioenergy pact to grow biofuel crops in the developing world to meet EU biofuel demands. The EU acknowledged that the use of food crops for biofuel production was based on wrong assumptions concerning climate change mitigation, and its support (...) has now shifted to second-generation nonfood crops. The bioenergy pact entails (a) biofuel crops production in developing countries, especially Africa, that in the absence of environmental and social regulations may lead to ethical trade-offs in land use (food vs. fuel) and (b) the use of transgenic technology that conflicts with the EU’s own vision of sustainable agriculture.

The use of marginal land (ML) for lignocellulosic biofuel production is examined for system stability, resilience, and eco-social sustainability. A North American prairie grass system and its industrialization for maximum biomass production using biotechnology and agro-technical inputs is the focus of the analysis. Demographic models of ML biomass production and ethanol farmer/producers are used to examine the stability properties of the ML system. A bio-economic model that maximizes the utility of consumption having the dynamics of MLs and the farmer/producers as (...) dynamic constraints is used to examine the effects of increased conversion efficiency, input costs, risk, and levels of base resources and inputs on the competitive and societal solutions for biomass production. We posit ML abandonment after biofuel production ceases could lead to permanent land degradation below initial levels that prohibit the establishment of the original flora and fauna. (shrink)

The rapid adoption of transgenic crops in the United States, Argentina, and Canada stands in strong contrast to the situation in the European Union (EU), where a de facto moratorium has been in place since 1998. This article reviews recent scientific literature relevant to the problematic introduction of transgenic crops in the EU to assess if there are specific reasons why transgenic crops have a potentially greater adverse impact on sustainable agriculture in the EU context than elsewhere. Sustainable agriculture integrates (...) three main goals: environmental health, economic profitability, and socioeconomic equity. Transgenic crops do not appear a suitable tool for sustainable agriculture in the EU due to specific environmental, economic, and socioeconomic reasons. Therefore, a moratorium on transgenic crops based on the precautionary principle should be officially adopted until proper risk assessment. In addition, agroecological alternatives to transgenic crops fit better the EU vision of agriculture. (shrink)
