La formation a \u00e9t\u00e9 men\u00e9e en partenariat avec le CIAT et S\u00e3o Tom\u00e9-et-Pr\u00edncipe (CIAT-STP) et financ\u00e9e par le Fonds international de d\u00e9veloppement agricole (FIDA). Elle a marqu\u00e9 une \u00e9tape importante vers le renforcement des syst\u00e8mes semenciers du pays et l'am\u00e9lioration de la productivit\u00e9 agricole. Cette initiative de renforcement des capacit\u00e9s a rassembl\u00e9 25 participants, dont 13 responsables d'\u00e9coles d'agriculteurs de terrain, quatre agents de vulgarisation et huit techniciens et chercheurs du CIAT. Gr\u00e2ce \u00e0 une approche d'apprentissage mixte comprenant des sessions en salle et des d\u00e9monstrations pratiques sur le terrain, les participants ont acquis une exp\u00e9rience concr\u00e8te. Ils ont \u00e9t\u00e9 form\u00e9s \u00e0 la multiplication des semences, \u00e0 la gestion des nuisibles et des maladies, aux proc\u00e9dures de contr\u00f4le de la qualit\u00e9 et aux technologies de propagation innovantes.<\/span>\u00a0<\/span><\/p>\n\n\n\n

La formation a \u00e9t\u00e9 con\u00e7ue pour relever les d\u00e9fis du syst\u00e8me semencier du pays en dotant les acteurs locaux des connaissances et des comp\u00e9tences n\u00e9cessaires pour produire du mat\u00e9riel v\u00e9g\u00e9tal sain et certifi\u00e9.\u00a0<\/span>\u00a0<\/span><\/p>\n\n\n\n

\u201c Le renforcement des capacit\u00e9s techniques dans les syst\u00e8mes semenciers est essentiel pour am\u00e9liorer la productivit\u00e9 agricole et garantir la s\u00e9curit\u00e9 alimentaire \u00e0 long terme \u201d, a d\u00e9clar\u00e9 le prof. Miclay Carvalho, directeur scientifique du CIAT-STP<\/span>\u00a0<\/span><\/p>\n\n\n\n

Repr\u00e9sentant l'\u00e9quipe IITA-CGIAR, le Dr Fotso Apollin, entomologiste \u00e0 l'IITA Cameroun, a d\u00e9clar\u00e9 : \u201c Cette initiative s'inscrit dans le cadre de la strat\u00e9gie globale de durabilit\u00e9 de l'IITA visant \u00e0 soutenir les institutions agricoles nationales et \u00e0 autonomiser les communaut\u00e9s locales par le transfert de connaissances \u201d.\u00a0<\/span>\u00a0<\/span><\/p>\n\n\n\n

La formation a \u00e9t\u00e9 mise en \u0153uvre en deux phases. La premi\u00e8re phase s'est concentr\u00e9e sur les animateurs des Champs-\u00e9coles des producteurs et les agents de vulgarisation, en mettant l'accent sur les techniques de production de semences certifi\u00e9es. La deuxi\u00e8me phase a cibl\u00e9 les chercheurs et techniciens du CIAT. Elle a introduit des technologies avanc\u00e9es telles que la propagation in vitro et l'hydroponie semi-autotrophe pour la production de semences de base. Les participants ont suivi des sessions th\u00e9oriques intensives, suivies d'exercices pratiques sur le terrain sur le campus du CIAT. L\u00e0, ils ont appliqu\u00e9 des techniques de s\u00e9lection de mat\u00e9riel v\u00e9g\u00e9tal sain, d'\u00e9tablissement de parcelles de multiplication, d'identification des ravageurs et des maladies, et de gestion de la qualit\u00e9 des semences.<\/span>\u00a0<\/span><\/p>\n\n\n\n

\u201c Les agriculteurs r\u00e9utilisent souvent le mat\u00e9riel de plantation des r\u00e9coltes pr\u00e9c\u00e9dentes sans renouvellement, ce qui contribue \u00e0 la baisse des rendements et \u00e0 la propagation des maladies. Cette formation aide les participants \u00e0 comprendre comment des syst\u00e8mes de semences de qualit\u00e9 peuvent transformer la productivit\u00e9 et am\u00e9liorer leurs moyens de subsistance \u201c, a expliqu\u00e9 le Dr Abang Albert, phytog\u00e9n\u00e9ticien \u00e0 l'IITA.\u201c<\/span>\u00a0<\/span><\/p>\n\n\n\n

Au-del\u00e0 des connaissances techniques, l'initiative a \u00e9galement renforc\u00e9 la collaboration entre les chercheurs, les services de vulgarisation et les communaut\u00e9s agricoles. En formant les animateurs d'\u00e9coles d'agriculteurs sur le terrain et les agents de vulgarisation, l'IITA-CGIAR contribue \u00e0 garantir que les pratiques am\u00e9lior\u00e9es b\u00e9n\u00e9ficient aux communaut\u00e9s agricoles de tout S\u00e3o Tom\u00e9-et-Pr\u00edncipe.\u00a0<\/span>\u00a0<\/span><\/p>\n\n\n\n

S'exprimant lors de la s\u00e9ance d'ouverture, Summer Metzer, sp\u00e9cialiste de la production agricole du projet COMPRAN, a soulign\u00e9 : \u201c la formation renforce les capacit\u00e9s locales en mati\u00e8re de production de semences, de certification et de gestion des nuisibles afin de b\u00e2tir un syst\u00e8me national de semences durable. Les techniciens form\u00e9s agiront en tant qu'acteurs du transfert de connaissances, acc\u00e9l\u00e9rant l'adoption de technologies de semences am\u00e9lior\u00e9es par les agriculteurs \u00e0 travers le pays \u201d.\u00a0<\/span>\u00a0<\/span><\/p>\n\n\n\n

IITA-CGIAR a dot\u00e9 le CIAT-STP et COMPRAN d'un ensemble complet de manuels techniques, de guides de terrain, de pr\u00e9sentations de formation et de r\u00e9f\u00e9rences de multiplication avanc\u00e9es couvrant la production de semences certifi\u00e9es pour le manioc, le ma\u00efs, la patate douce et l'igname.\u00a0<\/span>\u00a0<\/span><\/p>\n\n\n\n

Des mat\u00e9riels allant des outils de gestion des nuisibles et des maladies aux technologies innovantes telles que la propagation in vitro, la culture hydroponique semi-autotrophe (SAH) et le syst\u00e8me Triple S, ont \u00e9t\u00e9 officiellement transf\u00e9r\u00e9s afin de renforcer les capacit\u00e9s institutionnelles, de soutenir les futures formations d'agriculteurs et de conforter le d\u00e9veloppement d'un syst\u00e8me national de semences durable dans le cadre du projet COMPRAN, contribuant ainsi au renforcement institutionnel, soutenant le d\u00e9veloppement d'un syst\u00e8me national de semences plus structur\u00e9 et garantissant un impact durable au-del\u00e0 de la formation.<\/span>\u00a0<\/span><\/p>\n\n\n\n
