Southwest Ethiopia's cool, moist, and steep highlands differ from other African environments, and may have fostered distinct patterns of Holocene resource use and intensification. Prior to 2004, only a few archaeological projects probed eastern and northern margins of this region. The Kafa Archaeological Project (2004)(2005)(2006)) excavated ten caves and rockshelters in different environments in the heart of southwest Ethiopia to obtain a Holocene chronology and compare it with adjacent regions. At Kumali Rockshelter, middle Holocene deposits show use of a microlithic industry to obtain wild game, and excellent macrobotanical preservation promises to reveal changes in plant use from 4,700 14 C bp to the present. Ceramics and domestic animals appear at Kumali and Koka by~2,000 14 C bp, suggesting herding and pottery making appeared late and contacts with neighboring regions were tenuous. Technologically conservative people continued microlith production and sporadic rockshelter use into the eighteenth century CE.
RésuméLe haut plateau escarpé au climat frais et humide du Sud-ouest de l'Éthiopie se distingue des autres environnements africains et a favorisé des schémas variés d'utilisation et d'intensification des ressources Holocènes. Avant 2004, seuls quelques projets archéologiques ont exploré les bords nord et est de cette région. Le Kafa Archaeological Project (2004-2006) a fouillé dix grottes et abris sous roche, situés dans des environnements divers au milieu de cette région pour obtenir une chronologie holocène et la comparer aux régions voisines.
