• The Yobe valley is one of the many refugia that dotted the Chad basin after the commencement of the desiccation of the Sahara. It hypothetically must have been attractive to the population that had to move away from the aridized zone in search of favourable ecotones. As the Mega Chad receded from its Bama ridge shores, new lands were progressively made available for human occupation along the valley. It is one of the principal goals of the Yobe Valley Archaeological project to investigate how and when this new valley was occupied. This paper has been divided into three principal sections. The first section deals with the search for the earliest settlements of the Yobe valley. The excavations conducted at Garingada and Damakarwa were aimed at tackling this problem. The second section deals with the development of complexity. The excavation at Gambaru was directed towards this problem. The third section seeks to discuss on the bases of the excavations at the three sites, manenvironment relationship. The concluding part of the paper focuses attention on the problems and prospects of the Yobe Valley Archaeological Project.
