Faced with the degradation of natural resources linked mainly to the phenomenon of climate variability in Africa, the Assisted Natural Regeneration (ANR) strategy is more and more recommended to certain farmers in West Africa. This article therefore aims to assess the impact of Assisted Natural Regeneration on flora in agro-ecosystems in the southern Sudanian agro-climatic zone of Burkina Faso. The research took place on the outskirts of the Classified Forest and Partial Wildlife Reserve of Comoé Léraba located in the southwestern part of Burkina Faso. The field work on the identification of the floristic composition and the structure in the fields under ANR shows that the composition of the flora in the parcel of land under ANR contains 93.5% of the total of the species listed. This reveals the will of the producers to diversify the species in the fields under ANR. This study allowed the determination of the phytoecological characteristics of agricultural areas under ANR and encourages the popularization of ANR in the southern Sudanian zone, as a strategy for anticipating the degradation of natural resources which compromises agroforestry production.

Faced with the degradation of natural resources linked mainly to the phenomenon of climate variability in Africa, the Assisted Natural Regeneration (ANR) strategy is more and more recommended to certain farmers in West Africa. This article therefore aims to assess the impact of Assisted Natural Regeneration on flora in agro-ecosystems in the southern Sudanian agro-climatic zone of Burkina Faso. The research took place on the outskirts of the Classified Forest and Partial Wildlife Reserve of Comoé Léraba located in the southwestern part of Burkina Faso. The field work on the identification of the floristic composition and the structure in the fields under ANR shows that the composition of the flora in the parcel of land under ANR contains 93.5% of the total of the species listed.

Abstract: (french)
Face à la dégradation des ressources naturelles liée surtout au phénomène de la variabilité climatique en Afrique, la stratégie de Régénération Naturelle Assistée (RNA) est de plus en plus recommandée à certains exploitants agricoles d’Afrique de l’Ouest. Le présent article vise alors à évaluer l’impact de la Régénération Naturelle Assistée sur la flore dans les agro écosystèmes en zone agro-climatique sud soudanienne du Burkina Faso. La recherche s’est déroulée dans la périphérie de la Forêt Classée et Réserve Partielle de la Faune de la Comoé Léraba située dans la partie Sud-Ouest du Burkina Faso. Le travail de terrain sur l’identification de la composition floristique et la structure de la végétation dans les champs sous RNA montre que la composition de la flore dans les parcelles sous RNA renferme 93,5% du total des espèces recensées. Cela révèle la volonté des producteurs de diversifier les espèces dans les champs sous RNA. Cette étude a permis la détermination des caractéristiques phytoécologiques des espaces agricoles sous RNA et permet d’encourager la vulgarisation de la RNA dans la zone sud soudanienne, en tant que stratégie d’anticipation et d’atténuation à la dégradation des ressources naturelles qui compromet les productions agroforestières.
