Gracia, Barreiro-Hurlé and Pérez y Pérez investigate social preferences in Spain for sustainable biofuels and, in particular, the willingness to pay (WTP) for sustainable biodiesel. The European Union (EU) considers biofuels as an option to reduce GHG emissions. EU renewable energy directives introduced some requirements that biofuels should meet to be certified as sustainable. Results indicate that consumers are willing to pay, a premium of 5% for biodiesel. Authors identified two segments of consumers according to their WTP for the different biodiesel characteristics. One segment was more willing to pay for biodiesel while the other one attached more importance to fuelling convenience and biodiesel availability. Mulazzani et al. deals with the connection between food security and migration. The paper aims firstly to draw a general framework of this nexus and then to validate it using empirical literature on the African continent. Drivers of migration are never simple and well defined. Quite often, more than one cause (including economic, climatic and security drivers) contributes to migration. A few common points can be emphasized for the continent: due to structural and familiar characteristics, different strategies based on opportunity costs or risk minimization (including food security aspects) may emerge. Individuals often migrate following household strategies and investment, so land grabbing and land tenure security represent important drivers to be considered. Finally, gender issues need a special attention. Paper assesses the strategy of adopting labeling environmental and social issues and to what extent these labels could contribute to the promotion of Spanish olive oil to French consumers. Authors Erraach and Sayadi through the scenario method, highlight the criteria for choosing olive oil. The results show that the price, the brand, the organoleptic and sensory characteristics, cold pressure and origin are the most determining criteria for consumerchoice. Findings from a qualitative study performed to French consumers confirm that the Spanish olive oil is perceived as a lower quality. Environmental and/or social labeling, through institutional certification, could help to improve the perceived country's image. Paper investigates how food safety investment decisions are affected on the one hand by laws and on the other by firm's economic and organizational drivers. The data were collected by through a postal questionnaire submitted to 2,069 Italian meat companies. The authors Martino et al. show how regulation and freedom of contract act as drivers of food safety investments. They affirm that regulatory interventions are more effective if there is a private possibility to allocate investment decision rights with respect to the distribution of information between private and public agents and the degree of uncertainty. So information regarding the role of these collective bodies will become relevant in the near future in the context of expected changes in the EU's agricultural policy. El Bilali et al. highlight a methodological approach adopted to evaluate the environmental sustainability of quality agro-food products integrated in a regional quality scheme. Indicators measurable at the farm/firm level were selected in relation to the following environmental themes: biodiversity, land use and management, energy use and climate change, use of chemical inputs, and responsible management of by-products and waste. The presented approach represents a practical and innovative way to develop an information scheme for typical agri-food products and can be, with some refinement and contextualisation, easily scaled up to other territories.
