On doit se demander si la richesse évidente des morts de Kissi n’était pas le résultat visible d’un commerce d’or. Malheureusement, à Kissi comme ailleurs, nous ne sommes pas en mesure de donner une réponse positive à partir des seules données archéologiques. Mais si l’on admet que les Arabes au Maghreb ont déjà commencé pendant la conquête à frapper des pièces en or dont le matériel venait du sud, on n’échappe que difficilement à la conclusion qu’ils le tiraient d’une structure des relations commerciales existantes. Ces relations peuvent déjà dater de l’époque du 3e/ 4e AD, mais sont assez sûres pour l’époque byzantine, notamment pour le temps sous regard dans cette communication, le 6e et 7e siècle de notre ère.

Le rôle de l’action anthropique dans la dégradation des ressources naturelles à Niaogho-Béguédo
(2000)
La détérioration des conditions climatiques dans les pays du Sahel depuis plus de quatre décennies a entraîné la fragilisation de leurs écosystèmes et accéléré la dégradation des ressources naturelles dont les effets se répercutent durement sur les conditions de vie des populations. Mais si le facteur climatique est unanimement mis en cause, il ne faut cependant pas occulter la dimension humaine de la dynamique environnementale. En effet, les représentations de l’espace et la perception que les populations ont de leur environnement, les systèmes de production, le rôle des acteurs sociaux dans la gestion des ressources naturelles sont des facteurs qui déterminent également leur évolution. Au Burkina Faso, la dégradation des ressources naturelles a pris des proportions inquiétantes dans certaines régions. La persistance de la sécheresse a accéléré la dégradation des ressources en eaux, sols et végétation, avec une ampleur particulière dans certaines zones agro-climatiques. La présente étude est la synthèse d’une série de recherches effectuées à Niagho-Béguédo sur les déterminants anthropiques de la dynamique environnementale. Elle met en exergue les interactions entre les systèmes de production traditionnels, la gestion des ressources naturelles et leur conservation durable à travers les aspects suivants: • les facteurs explicatifs des transformations du milieu. • La logique paysanne des changements environnementaux et les réponses face à ces changements. • Les attitudes des populations à l’égard des actions entreprises par l’état pour la sauvegarde de l’environnement.

The Nigerian agricultural sector deserves to be studied not less for the contribution of such knowledge to our understanding of the past, and present, but more for the usefulness of such knowledge in shaping the sector. The role that agriculture plays in Nigeria’s national economy since her independence may be determined by considering first, the changing structure of the national economy. As the national economy changes, also the role of agriculture. The observed structure at successive periods thus reveals the contribution that agriculture makes to the national economy. A total picture could also be presented through an examination of the contribution of agriculture to the gross domestic product GDP, over the years. It is also possible to add to the above presentation, the annual production of each agricultural crop over the period, or the productivity of the individual farmer as the years pass by. No doubt, the role of agriculture shall not remain static, for as deliberate efforts are made to develop the economy, the agricultural sector is also affected, although several endogenous factors also influence development within the sector. An emperical approach to the understanding of what is happening within the sector is to be prefered and such is documented in small scale studies conducted already by such scolars as FRICKE (1965), TIFFEN (1976) and MALCHAU (1999a+b).

This paper is concerned with the transition from hunting and gathering to food production in West Africa, based on evidence from the Sahel Zone of Burkina Faso compiled by field research during the last years. Our study intends to enhance the knowledge about the West African versions of this transition, traditionally seen as one of the most fundamental changes in human prehistory. Embedded in an interregional program the Sahel Zone of Burkina Faso has proved to be one of its most unexpected examples.

This paper, which is based on field research in Doron Baga and Maiduguri, attempts to describe and analyse the main determinants of the fish trade in North-east Nigeria with Doron Baga as the main focus. Fish is a significant source of income and a principal trade commodity, bringing together the remote fishing community of North-east Nigeria with the major urban centres of the Southern part of the country. In order to get an insight into the workings of the fish trade, indepth interviews were conducted with fatoma (or dealers), traders and transporters in Doron Baga and Maiduguri. In addition, the authors utilised documentary sources to supplement the data collected from the field. For instance, a number of postgraduate dissertations, archival accounts as well as journal articles and books were consulted. After giving a brief introduction of the development of the long distance trade in fish, the paper discusses the role of the fatoma, means of transportation, value and volume of the trade. The study focuses on the period 1997-1999, during which substantial part of the data used were collected.

Les ferrières sont par définition les amas des déchets de la réduction du fer. De par son origine elles constituent des lithosols qui ont beaucoup évolué dans l’espace et dans le temps. A notre connaissance très peu d’études se sont penchées sur cette végétation qui couvre actuellement les sites de réduction du fer. L’inventaire floristique de plusieurs sites en zone soudanienne montre la fréquence de certaines espèces sur les ferrières. L’étude de la chorologie de toutes les espèces confondues ligneuses et herbacées, montrent que la plupart sont constituées par des espèces zoochores et quelques espèces anémochores. Elles sont disséminées principalement par les animaux d’élevage, par les oiseaux. Cette communication synthétise les données des différentes prospections et les premiers résultats de nos observations et analyses. Elle a deux objectifs : de montrer l’importance des activités anthropiques dans la formation du paysage végétal d’une part, et d’autre part de mettre en évidence le processus de colonisation des sols nus et des ferrières en zone soudanienne.

Les fouilles archéologiques de Gandefabou effectuées courant Novembre - Décembre 1996 constituent une grande première expérience du Laboratoire d’Archéologie de l’Université de Ouagadougou dans le Sahel burkinabè. Elles ont été exécutées grâce à une subvention financière de l’Ambassade Royale des Pays-Bas à Ouagadougou et au soutien logistique du Programme Sahel Burkinabè - Pays-Bas (PSB/PB) basé à Gorom-Gorom, capitale de la province de l’Oudalan. Ces travaux au double objectif scientifique et touristique s’insèrent dans une politique locale de développement économique avec le maintien in situ et la protection de certains vestiges pour en faire un musée de site.

The study investigates elements influencing agricultural development in villages of the hinterland of Gombe, Gombe State, Nigeria. It aims to discover changes in socio-economic and socio-cultural interactions that exist among household, region, nation and world market. Of special interests are rural households as well as wholesale markets where dynamic processes in the structure of agricultural enterprises and the individual reasons of innovations are recognisable. The final objective of the study is to analyse the agricultural sector in the investigated villages in time and space, by typifying rural households, there strategies of action in relation to different factors: for example, farmsize, cultivation techniques and marketing of agriculture products. The study is also interested in operational profits and costs of farms, income of households as well as expenditures, etc. Because of the fact that statistical work is still going on, it is only possible to present a small portion of the results. Namely, the change in cultivation and marketing of farm products with special emphasis on cash crops during the last 30 years.

Traditional land rights in Dagara and Sisala societies in Burkina Faso and Ghana which were stateless in pre-colonial times are closely connected with the concept of earth-shrine parishes under the protection of a local land god and ideally under the control of the “first-comers” to the area. The earth priests perform regular sacrifices at the shrine and allocate land to later immigrants as well as the right to build houses and to bury their dead, often in exchange for gifts. The international border between Ghana and Burkina Faso, which was drawn up in 1898 and runs along the 11th parallel, often cuts across earth-shrine parishes. Particularly since the border demarcation exercise in the 1970s, the spatial separation of the Sisala earth priests on one side of the border from the Dagara immigrants on the other side has given rise to intricate conflicts over land rights. The paper will present the history of one such conflict and look at the various landrelated discourses – traditionalist, nationalist, and Christian – which the adversaries put forward in order to substantiate their claims.

One of the powerful conventional images of pre-colonial Africa is that of a continent of more or less immobile ethnic groups, living since time immemorial on their ancestral lands, steeped in their traditional cultures. In this image, Africa appears like a mosaic, with clearcut ethnic boundaries, each sherd representing a different people cum language cum culture cum territory. Since a number of years, however, historians and anthropologists of Africa have insisted that this image is misleading. Most pre-colonial societies were characterised by mobility, overlapping networks, multiple group membership and the contextdependent drawing of boundaries. Communities could be based on neighbourhood, kinship and common loyalties to a king, but this did not absolutely have to include notions of a common origin, a common language or a common culture. Our own research on the West African savannah has also shown the enormous importance of mobility. Among the societies of southern and southwestern Burkina Faso, for instance, which several projects have studied, there is hardly a single village whose history has not been characterised repeatedly by the arrival and settlement of new groups and the departure of others. In some cases, we can even speak of systematic practices of multilocality.
