چکیده
Résumé G. E. Brooks — Un schéma provisoire de l'histoire de l'Afrique occidentale, fondé sur sept périodes climatiques (de ca. 9000 av. J.-C. au XIXe siècle). Examen de l'évolution historique de l'Ouest africain au cours des sept ères climatiques s'étendant sur onze millénaires. Une périodisation construite à partir des changements climatiques fournit un éclairage significatif sur des phénomènes tels que les structures du peuplement, la diffusion des cultigènes et des animaux domestiques, le développement des routes commerciales reliant les écosystèmes, l'usage de la cavalerie pour la guerre et dans la genèse des États. Eh outre, la détermination des systèmes climatiques contribue à l'établissement de périodisations historiques indépendantes des chronologies d'inspiration européenne.
