La principale priorit\u00e9 de l'IITA est de garantir un avenir stable et s\u00fbr sur le plan alimentaire pour l'Afrique subsaharienne. Pour ce faire, nous nous concentrons sur des th\u00e8mes de recherche cl\u00e9s ax\u00e9s sur les cultures vivri\u00e8res de base, notamment la banane et la banane plantain, le manioc, le ni\u00e9b\u00e9, le ma\u00efs, le soja et l'igname.<\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t

La majorit\u00e9 de la population en Afrique vit dans des zones rurales et d\u00e9pend de ce qu'elle cultive pour se nourrir. Cependant, la plupart d\u00e9pendent d'un aliment de base principal qui fournit des calories mais g\u00e9n\u00e9ralement des nutriments inad\u00e9quats, conduisant \u00e0 la malnutrition ou \u00e0 la \u201c faim cach\u00e9e \u201d.\u00a0Lire la suite<\/a><\/span><\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\n<\/div>\n

\u00c0 l'IITA, nous nous pr\u00e9occupons particuli\u00e8rement de la nutrition et de la sant\u00e9, de l'implication des femmes et des jeunes dans l'agriculture et de l'expansion des opportunit\u00e9s d'agroentreprise. Nous contribuons \u00e0 garantir le d\u00e9veloppement de politiques et d'institutions favorables aux petits producteurs afin d'accro\u00eetre leurs revenus gr\u00e2ce \u00e0 un meilleur acc\u00e8s aux march\u00e9s. Nous examinons les strat\u00e9gies de r\u00e9duction de la pauvret\u00e9 et les cadres politiques propices pour garantir l'impact de notre travail et am\u00e9liorer la qualit\u00e9 nutritionnelle des produits alimentaires tout au long des cha\u00eenes de valeur des cultures. Nos r\u00e9sultats de R4D sont commercialis\u00e9s sous forme de produits agricoles, contribuant ainsi \u00e0 stimuler des partenariats public-priv\u00e9 efficaces.<\/p>

Nos th\u00e8mes de recherche sont con\u00e7us pour apporter des solutions aux d\u00e9fis agricoles et de d\u00e9veloppement auxquels font face tant les communaut\u00e9s rurales d'agriculteurs que les populations urbaines, tout en mobilisant les int\u00e9r\u00eats commerciaux pour stimuler l'\u00e9conomie. \u00c0 travers notre recherche, nous voulons nous assurer que la croissance \u00e0 long terme du secteur agricole inclut et profite \u00e0 tout le monde dans la r\u00e9gion.\u00a0\u00a0Lire la suite<\/a><\/span><\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\n<\/div>\n

Le d\u00e9veloppement de cultures saines va de pair avec l'am\u00e9lioration des cultures. Nous d\u00e9veloppons des solutions \u00e9cologiquement durables, \u00e9conomiquement rentables et socialement acceptables pour la lutte contre les ravageurs, les agents pathog\u00e8nes et les mauvaises herbes, ainsi que contre les contraintes li\u00e9es au changement climatique. Nous promouvons \u00e9galement des options prometteuses de gestion des cultures pour des conditions climatiques et de syst\u00e8mes de culture sp\u00e9cifiques, ainsi que des approches qui facilitent la disponibilit\u00e9 et la diffusion de mat\u00e9riel de plantation de bonne qualit\u00e9 aupr\u00e8s des agriculteurs. En se concentrant sur la gestion des ravageurs et des maladies, la distribution de semences saines et le contr\u00f4le des toxines, l'IITA peut garantir que nos vari\u00e9t\u00e9s de cultures am\u00e9lior\u00e9es restent saines et productives.\u00a0Lire la suite<\/a><\/span><\/p>

Nous travaillons sur la gestion des ressources naturelles, en particulier sur l'intensification durable des syst\u00e8mes agricoles. Nous \u00e9tudions les processus biologiques du sol, les organismes b\u00e9n\u00e9fiques et leurs m\u00e9canismes, les strat\u00e9gies de gestion et les intrants du sol garantissant une utilisation efficace des nutriments. Nous d\u00e9veloppons des pratiques de gestion int\u00e9gr\u00e9e de la fertilit\u00e9 des sols les mieux adapt\u00e9es avec les communaut\u00e9s locales, incluant l'association de germoplasmes et de technologies am\u00e9lior\u00e9s, ainsi que l'utilisation des innovations des agriculteurs.
