For a vegetation geographer and an anthropologist to come together to write on the settlement histories of segmentary societies in the West African savanna is unusual or at least rare. A few words on the origin of this cooperation therefore seem appropriate. For over ten years, in the context of an interdisciplinary research program at the Universität Frankfurt am Main, archeologists, anthropologists, linguists, botanists and geographers have been working together on the history of cultures, languages, and natural environment of the West African savanna, especially the interaction between human activity and the natural environment. That one should actually be speaking in many cases of a culturally mediated “landscape” rather than a “natural environment” is one of the outcomes of the research projects, which have focused mainly on different regions of Burkina Faso (in the sahel and Sudanese zone) and the Lake Chad area of northeast Nigeria.The present paper has emerged from a botanical and an anthropological-historical project on the history of vegetation and of settlement in south and southwest Burkina Faso. This history has been shaped by the great expansion of the Dagara-speaking population. In the last two hundred years (possibly longer), small groups of Dagara patrilineages, related and allied to one another, have migrated north and northwest, probably from the region around Wa in present-day Ghana, and have founded numerous new settlements—a process of land appropriation that is still going on today, though with changed circumstances regarding land rights (see map 1).

Regional Flow

Shear zones of the Paleoproterozoic Eburnean accretionary Orogen (West African craton) are investigated by means of large-scale structural mapping. Regional scale (10-100 km) mapping was based on the aeromagnetic survey of Burkina Faso and craton-scale (1000 km) mapping on a compilation of fabric data. At both scales, shear zones are arranged as an anastomosed transpressional network that accommodated distributed shortening and lateral flow of the orogenic lithosphere between the converging Kénéma-Man and Congo Archean provinces. Structural interference patterns at both scales were due to three-dimensional partitioning of progressive transpressional deformation and interactions among shear zones that absorbed heterogeneities in the regional flow patterns while maintaining the connectivity of the shear zone network. Such orogen-scale kinematic patterns call for caution in using the deformation phase approach without considering the “bigger structural picture” and interpreting displacement history of individual shear zones in terms of plate kinematics. The West African shear zone pattern is linked to that of the Guiana shield through a new transatlantic correlation to produce an integrated kinematic model of the Eburnean-Transamazonian orogen.

Simultaneous Implementation

This article broadens analytic perspectives on the effects of government interventionsby looking at the interaction of two distinct but simultaneous policy initiatives: involuntary resettlement and structural adjustment. Case study data from the Bafing valley in Mali show that simultaneous implementation of these two initiatives reinforced the economic growth of the zone but increased negative environmental effects.Key Words: Mali, resettlement, structural adjustment, sahel, environmental degradation, economic development, river basin development, privatization, liberalization.

Plant Animal Interactions

Levels of leaf damage due to insect folivory have been investigated in forests of different latitudes all over the world, but most research has concentrated on a few common forest types. Most studies of insect herbivory were conducted in (sub)tropical rain forests (Barone 1998, Basset 1996, Coley 1983, Lowman 1985), or in temperate forests (Landsberg & Ohmart 1989, Lowman & Heatwole 1992). In contrast, little is known about insect folivory of woody plants in tropical savannas (Fowler & Duarte 1991, Marquis et al. 2001, Ribeiro 2003, Stanton 1975), and no such data are available for the West African savanna ecosystem (Andersen & Lonsdale 1990). Savannas cover about 40% of the land surface of Africa and 20% of the world (Scholes & Walker 1993), and savanna trees may host considerable numbers of insects, including many herbivores (Grant & Moran 1986, Mody et al. 2003). Therefore, insect herbivory can be considered a potentially important aspect of plant–animal interactions for vast areas of tropical ecosystems, where it has been studied remarkably rarely so far.
