Abstract

Ce travail est consacré à une question qui fait débat depuis quelque temps : c'est celle du lien entre les suicides de fermiers et les performances de la technologie du coton Bt (Bacillus thuringiensis) en Inde. Nous proposons un cadre de modélisation dynamique qui prend en compte le risque de la résistance des insectes aux plantes OGM. Face au problème de résistance des ravageurs cibles aux toxines de Bt, l'agriculteur indien revient à l'application massive de produits phytosanitaires. Le recours à l'utilisation intensive de pesticides a fait augmenter les coûts de production qui, combinés avec le prix exorbitant de nouvelles semences, a entraîné des situations de surendettement et le suicide de milliers d'agriculteurs de coton indiens. Nous montrons que le suicide des agriculteurs dépend essentiellement d'un niveau critique de risque qui dépend à son tour d'un seuil de nuisibilité économique. Si le niveau de la population d'insectes pousse au-delà du seuil de tolérance, l'utilité devient négative et par conséquent l'agriculteur choisira le suicide.
