Environmental and economic assessment of crops as a source of proteins under different production systems

Dans le cadre d’une réflexion générale sur les alternatives durables à la suppression des farines carnées dans l’alimentation animale, l’introduction et le renforcement des oléoprotéagineux dans les systèmes de production apparaissent comme les solutions les plus crédibles. Néanmoins, le caractère durable des solutions envisagées doit être évalué sur des bases techniques, environnementales et économiques qui permettront, en outre, d’estimer l’acceptabilité par les agriculteurs des scénarios proposés.
Abstract
The major purpose of this project is to provide an environmental and economic assessment of the introduction of protein crops in existing arable systems. As a pertinent environmental evaluation has to be based upon a systemic approach integrating time through crop rotation and ad hoc technical issues, this assessment will be conducted according to the following steps: i) identification and design of technical scenarios (soil type x crop rotation) adapted to a given region, ii) environmental evaluation based on an environmental balance on the duration of the crop rotation, iii) impact of different external economical scenarios such as world price of oil and grain, public subsidies… on farmers’ decisions. This project is setup against the existing scientific and technical background, a review of the existing bottlenecks is proposed and these are identified in terms of scientific questions.
Key words: oil and protein crops / cropping systems / environmental balance / economy
