Caractérisation des systèmes de production et des ressources fourragères dans un terroir test de la zone soudanienne du Burkina Faso

The Sudanian zone of Burkina Faso is considered as the area with the highest agro-sylvo-pastoral potential of the country. The aim of this study was to characterize the production systems and the status of forage resources from two contiguous land sites in the Southwest of the country. The methodolo...
