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...

A lab experiment evaluates the consequences of the palm oil controversy on consumers' willingness to pay (WTP) for food products. Palm oil production induces environmental damages, and its consumption presents a health risk. However, the production of alternative oils raises land use issues. In...

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...

A mathematical programming model is developed and associated to a spatial pattern index (Ripley L-function) to analyse the optimal reserve design and implementation for the Little Bustard conservation in Plaine de Niort. The model structure corresponds to three spatial levels, fields, farm and...

Une expérience de laboratoire a évalué la disposition à payer des consommateurs pour des produits alimentaires avec et sans huile de palme. La production d'huile de palme provoque des dommages environnementaux, et sa consommation présente un risque pour la santé. Cependant, la production...

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,...

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...

"Sugar is one of the most highly protected agricultural commodities worldwide. This protection depresses trade opportunities and the prices received by exporters without preferential market access. For this reason, dialogues about sugar policy are often polarized and short sound bites caustic....

The paper provides an analysis of the impacts of the biofuel policy on the French arable crop sub-sector. The model used is a biofuel supply model composed of an agricultural module and an industrial biofuel processing module. The agricultural supply model is an aggregation of 1094 farm models,...
