Abstract

Un modèle de programmation linéaire est utilisé pour observer les effets de scénarios de découplage des aides de la politique agricole commune (PAC) sur les exploitations de trois éleveurs de bovins des Pays-de-la-Loire (un laitier avec taurillons, un naisseur engraisseur et un engraisseur spécialisé intensif). Le modèle maximise le revenu sous l'action de contraintes techniques et administratives. L'objectif est d'évaluer l'effet du découplage des aides sur les marges de manoeuvre des exploitants et de mesurer leur impact sur l'extensification de la production, dans les différents systèmes étudiés. S'il est possible, globalement, de parler d'effet redistributif des soutiens en faveur des exploitations les plus extensives, la mise en oeuvre de modes de production plus extensifs est subordonnée à une adaptation plus complexe de l'exploitation. L'extensification semble d'autant plus difficile à observer, dans les zones de production intensive des Pays-de-la-Loire, que les potentiels de terre sont élevés et que la concurrence de la production céréalière est forte.
