L\u2019exp\u00e9rience de Jena (Land de Thuringe, Allemagne) \u00e9tudie les effets de la diversit\u00e9 v\u00e9g\u00e9tale sur les interactions trophiques et les cycles des \u00e9l\u00e9ments. Cet article \u00e9tablit les principaux r\u00e9sultats obtenus apr\u00e8s 15 ans d\u2019exp\u00e9rience.

\nD\u2019une mani\u00e8re g\u00e9n\u00e9rale, la biodiversit\u00e9 est un moteur important du fonctionnement des \u00e9cosyst\u00e8mes, engendrant, dans certains cas, la stabilit\u00e9. La richesse sp\u00e9cifique en v\u00e9g\u00e9taux est corr\u00e9l\u00e9e positivement avec la diversit\u00e9 des organismes d\u2019un \u00e9cosyst\u00e8me. De m\u00eame, le stockage de carbone augmente fortement avec cette richesse.
\nUn r\u00e9sultat phare de cette \u00e9tude est l\u2019effet positif qu\u2019a la richesse sp\u00e9cifique en plantes sur la biomasse. Les r\u00e9sultats de l\u2019exp\u00e9rience de Jena ont \u00e9galement \u00e9t\u00e9 envisag\u00e9s dans le contexte des pratiques agricoles men\u00e9es en prairies. On constate alors que l\u2019effet d\u2019une augmentation de la richesse sp\u00e9cifique en plantes sur la biomasse v\u00e9g\u00e9tale est aussi important que celui d\u2019une agriculture plus intensive utilisant des fertilisants et augmentant la fr\u00e9quence des fauches. Ainsi, des prairies de haute valeur biologique sont multifonctionnelles et peuvent fournir des services \u00e9cosyst\u00e9miques int\u00e9ressants pour l\u2019agriculteur, notamment en termes de production.
