Le milieu naturel de la zone soudanienne du Tchad se dégrade essentiellement sous l'effet de la pression anthropique. Des enquêtes ont révélé une proportion importante de jeunes de moins de quinze ans. L'élevage et l'agriculture ont une forte intégration. Les tests de FISHER et de STUDENT ont permis de constituer cinq groupes d'espèces ligneuses homogènes, d'établir leurs régressions et de quantifier leur biomasse foliaire. L'étude du comportement alimentaire des ruminants sur les parcours a permis d'identifier les espèces fourragères recherchées, refusées ou moyennement consommées. Le bilan fourrager a permis d'évaluer la biomasse végétale disponible. Les capacités d'accueil du système agro-sylvo-pastoral des trois terroirs sont entamées.Un cadre institutionnel du système d'information sur l'environnement est proposé pour assurer la compatibilité, la circulation, la valorisation et le partage des données de différentes institutions. Le contrôle continu et la poursuite des recherches écologiques à long terme proposés fourniront aux gestionnaires les éléments à la prise de décision dans la gestion durable des ressources renouvelables.
