Abstract

Grâce aux avancées méthodologiques sur la prise en compte des outputs indésirables dans la modélisation des technologies de production, cet article permet d’évaluer l’éco-efficience de 51 exploitations laitières de La Réunion selon le point de vue de trois acteurs : l’éleveur, la coopérative et la société. Si l’analyse retient le scenario désirée par la société comme celui conforme à la plus forte diminution des quantités globales d’outputs indésirables, on constate néanmoins qu’en termes d’indicateurs environnementaux (excèdent azote/litre de lait et gaz a effet de serre émis/litre de lait), le scénario de la coopérative qui vise à maximiser la production laitière aboutit aux mêmes ordres de grandeur. Cependant, l’augmentation des couts suggérée par ce dernier scenario pourrait être un frein a sa mise en œuvre, compte tenu des charges déjà très élevées auxquelles font face les producteurs réunionnais. La vision de l’éleveur souhaitant améliorer sa productivité globale a dotations factorielles constantes apparaît alors comme satisfaisante en permettant une progression assez significative de la production à niveau de gaz à effet de serre (GES) et d’excédents azotés (EA) inchangé.
