[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...

[fre] L'analyse des relations entre l'intensification et l'efficacité en agriculture est abordée ici à l'aide d'un modèle permettant de montrer que l'optimum au niveau de l'exploitation et le coût unitaire de production minimal ne sont pas nécessairement obtenus au même niveau...

[fre] Une« fonction de production d'ingénieur », qui fait appel à la fois à un simulateur de croissance de plantes et à de la programmation linéaire sous contrainte de risque, est utilisée pour analyser les conséquences de la réforme « Me Sharry » sur les revenus et sur...
