En mars 2007, le Conseil européen a annoncé qu’à l’horizon 2020, une proportion minimale de 10 % de biocarburants devrait être incorporée dans les carburants utilisés pour le transport routier. Les pouvoirs publics communautaires mettent en avant trois facteurs principaux pour...

A l'aide d'un modèle régional d'offre optimisant le revenu agricole des exploitations sous un ensemble de contraintes et simulant parallèlement les évolutions des structures agricoles sur la période 2002-2012, les impacts du compromis de Luxembourg sur les revenus et sur les structures...

This paper addresses the issue of designing policies for habitat conservation on agricultural land. The case under study requires a non-aggregated spatial distribution of the fields to be enrolled in an agri-environmental programme. A spatially explicit mathematical programming farm-based model,...

A lab experiment evaluates the consumers’ willingness to pay (WTP) for food products made with and without palm oil. Palm oil production induces environmental damages, and its consumption presents a health risk. However, the production of alternative oils raises land use issues. In the...

Linseed for feeding dairy cows reduces methane emissions and increases the omega-3 content of milk. In a lab experiment, milk bottles from cows fed a diet with or without linseed were offered to French participants for eliciting their willingness to pay (WTP). Successive messages highlighting...

An experiment was conducted in France to evaluate the impact of health and environmental information on consumers’ choices between conventional and organic apples. Results show that additional and precise messages about both pesticides use and pesticides residues significantly impact...

The objective of this study is to improve evaluations of the future use of biomass sources in Sweden and France by representing the high spatial variations of the supply and cost of biomass sources in energy system models. The proposed methodology considers a high spatial disaggregation of...

[eng] New tools to analyse the effects of future cap reforms on the farms . Since 1990 one is witnessing a new interest for models of simulation which function at the farm level. They have allowed to make projections of the CAP reform. They represent faithfully the regional agriculture. At INRA...
