, and siltstone. The source of these sediments was mainly from erosion of the Archaean lithologies summarized above; the basal conglomerate is interpreted as a debris-flow deposit in a fluviatile environment of decreasing depositional flow energy (Mapeo et al. 2004: 7, 11-13). The Moeng Formation

limitations to the productivity of the landscape in the provision of environmental goods and services, such as agricultural produce, are caused by the underlying geology and the soils that develop upon these materials. The high-energy fluvial environment within the Niger valley and that of its tributaries

trajectories limit the amount of possible flakes produced per core (see Fig. 10). This would also likely result in a need for increased raw material collection. Overall, the cost-efficiency of flaking at swt is more expensive in terms of energy and raw material when compared to the opposite trends at

The most complete form is the excavated example from Birnin Lafiya (Trench 3/10), where multi-element architectural spaces

faced by the inhabitants of medieval Dendi were not related so much to warfare as to the high-energy fluvial environment which acted as a constraint on settlement location due to seasonal flooding risks (Laïbi et al., this volume). As we have said, the bulk of our archaeological evidence in Dendi

that “waste energy” is an important component in explaining material-behavioural variation which utilises and stabilises population levels under the local resource carrying capacities (Wenke 1989, 1991). Environment perturbations cause resource fluctuations, which impact upon the geographic positioning
