Principale activité des ruraux nigériens, l’agriculture fait face à des problèmes récurrents de baisse de rendements conduisant à la paupérisation et à l’insécurité alimentaire des ménages qui l’exercent. Cette étude conduite à Karma vise la caractérisation des systèmes de production du mil et de niébé pluvial en vue de connaître leurs fonctionnements et leurs diverses interactions dans un contexte de changement climatique. Pour cela, une enquête a été conduite sur un échantillon de 90 ménages d’exploitants du mil et niébé pluvial. L’étude a montré que les systèmes de production sont regroupés en trois types selon la méthode d’Analyse en Composantes Principales couplée à la classification de Nuées dynamiques. Il s’agit du système de production agricole pure (Type A), du système agroforesterie (Type B) et du système agropastoral (Type C). Le type (A) occupe une superficie moyenne de 1,5 hectares. Il est scindé en système de cultures sèches simple et système de cultures sèches associé au maraîchage. Le type (B) s’effectue sur 2,18 hectares et le type (C) sur une superficie moyenne de 3,25 hectares. Ainsi, le type (C) est plus performant que le type (B) qui l’est plus que le type (A). English title: Typology of farms producing millet and rain-fed cowpeas in the rural commune of Karma Main activity of nigeriens’ rural, agriculture faces recurring problems drop in yields leading to pauperization and food insecurity of the households that exert it. This study conducted in Karma aims to characterize millet and rain-fed cowpea production systems with a view to understanding their functioning and their various interactions to enable producers to better cope with climate change. For this, a survey was conducted on a sample of 90 households farms of millet and rain-fed cowpea. The study showed that production systems are grouped into three types according to the Principal Component Analysis method coupled with classification. of dynamic clouds. These are the pure agricultural production system (Type A), the agroforestry system (Type B) and the agro-pastoral system (Type C). Type (A) occupies an average area of 1.5 hectares. It is split into a simple dry crop system and a dry crop system associated with market gardening. Type (B) takes place on 2.18 hectares and type (C) on an average area of 3.25 hectares. Thus, type (C) is more efficient than type (B) which is better than type (A).
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
