Gestion durable de la santé des cultures

En France et dans le monde, les systèmes agricoles et alimentaires de demain devront conjuguer les trois piliers du développement durable : la performance économique, la performance sociale et la performance environnementale. Un champ d’application concerne la capacité à produire des récoltes en quantité et qualité.

Pour préparer ce défi, la recherche agronomique doit intégrer autour d'objectifs partagés des approches relevant de multiples disciplines, de la biologie à l'écologie en passant par les sciences socio-économiques. Plus globalement, cette démarche contribue à l'émergence de l'agro-écologie comme une discipline scientifique à part entière. C'est pour cela que le métaprogramme SMaCH pour Sustainable Management of Crop Health (Gestion Durable de la Santé des Cultures) a été mis en place par l’Inra.

Nid de chenille processionnaire dans un pin.. © Inra, ROUSSELET Jérôme

En étudiant l’expansion de la processionnaire du pin, l’Inra a mis en évidence l’impact des paysages dans la dynamique spatiale des bioagresseurs. À terme, ces travaux déboucheront sur des outils destinés aux gestionnaires des territoires pour tenter de mieux contrôler ces organismes indésirables.
