La production agricole occupe une grande partie de la surface non bâtie. Pour cette raison, il est important pour une agriculture qui se veut durable de mieux comprendre les impacts environnementaux qu’elle génère et de les intégrer dans une analyse de cycle de vie sous une forme appropriée. La 10e plateforme sur les analyses de cycle de vie dans l’agriculture d'Agroscope qui s’est déroulée sur le site de Reckenholz à Zurich a montré les défis que pose le développement de nouvelles méthodes et de nouveaux modèles d'utilisation du sol à différentes échelles spatiales.
