Influence des activités agricoles sur la végétation le long d’un gradient pluviométrique nord-sud du Burkina Faso

Evaluation of the ecological state of Burkina Faso landscapes is necessary to understand human action on environment. This study aimed at characterizing the study sites to understand interactions between climate, humans and ecosystems along a rainfall gradient. The study was carried out along anthro...
