Over approximately the last 200 years, north-west Ghana and large areas of neighbouring southern Burkina Faso were the stage for a highly successful expansion of Dagara-speaking peoples. Probably setting out from an area around Wa, small groups of Dagara migrated towards the north, some of them taking a westward route, crossing the Black Volta river into today’s Burkina Faso. They rarely advanced into nomansland but rather displaced peoples such as Sisala-, Dyan-, Phuie- and Bwamu-speaking groups, who then moved further west and north. Today, the Dagara occupy about 3500 km2 in southern Burkina Faso, where they represent the sixth largest language group. In this paper I wish to explore the history of the north-west frontier of Dagara expansion and the interaction between the “land-owning” Phuo and the incoming Dagara.

The aim of our project B6 “Towards a genesis of the ethnolinguistic situation at the southern and western fringes of lake Chad basin” within SFB 268 “West African Savannah” is to analyse the emergence and development of the complex presentday ethnolinguistic patterns in a region which may be historically labelled as southern and western periphery of the Borno empire. For the first time, a model of migratory routes was put forward based on combined research efforts of the disciplines involved in our project. Below we shall attempt to summarise the main points and reflections of our findings. Our specific approach as a whole is based on applying the respective research methods of the individual disciplines represented in our project, namely anthropology, ethnomusicology, history and linguistics and eventually on integrating the results into a systemically coherent picture

The conflict I refer to happened at the beginning of the 1998 farming season when the distribution of land started. The seasonal migrants went into the village area were they had been farming since many years, they gave their contributions and payments to the respective officials and started to prepare the land. Shortly after they had started to plant the beans – the main cash crop beside fishing – they were harassed by armed people and had to leave the area. Only several weeks later they were able to go back to their prepared fields and proceeded with their farming business. The question I want to concentrate on is related to the topic of the ethnological sub-project – “Community building in newly founded settlements in the Lake Chad area” – and can be specified as “What do conflicts tell us about the community and people involved?”

The investigations carried out within the project in NE-Nigeria since 1989 have been focussing on the late Pleistocene and Holocene landscape development of the south eastern Chad basin. Areas of interest include palaeodune fields, clay plains and former beach ridge systems of Lake Chad. Transgressions and regressions of Lake Chad played an important role in the younger landscape history of NE-Nigeria and have also caused great environmental changes. The term „Megachad“ is well known and describes an enormous lake with an extension comparable with the Caspian Sea of today. The term „Microchad“ stands for the other recent extreme in terms of the lake dimensions varying during the times. Environmental changes in the surroundings of Lake Chad are closely connected with transgressions and regressions of the lake. These lake level changes can be climatically induced as well as non-climatically, due to human impact. Nearly all land units have more or less been influenced by the lake, spatially as well as temporally. It is important, though, to notice the scales of the changes. Some changes took place in a millennial scale, some in the scales of centuries or decades, and at least – as can be observed every year – in a seasonal scale.

Summary and evaluation
(2000)
The geographical analysis of the Savannah Zones of north-eastern Nigeria revealed a basic insight on the differentiated development at the meso-regional level: The northern districts had a much lower population increase than the average. It was already arid land before the dramatic reduction of precipitation since the late 1960s. The quality of the soil for farming is rather poor despite specific minerals which give grass during the very short growing season a higher nutritional value than further south. Through studies at the local level, it became evident that on one side this is an area of out-migration of the local population but on the other side we have to register the influx of migrants from the even more dryer northern districts including Niger Republic. The rate of urbanisation in Nigeria increased rapidly from 15 to 36 %. Northern capitals like Kano and Maiduguri multiplied their number of inhabitants seven times but were overtaken by Gombe’s growth. In any case they are centres of social and cultural change as the preliminary findings of H. BALZEREK concerning the boom-town Gombe revealed. But social tensions seem to be inevitable as religious movements not only in big towns like Kano but even in Gombe were already analysed by WATTS (1993, 61). The bearer/ carriers of this movement are landless people who did not migrate to new land in the country side, they are hoping for new jobs in an urban environment. The social structure has changed since the time of the old Hausa towns, but their reliance on surplus of labour force appears to have continued.

The search for persistent elements in nature and culture, which comprises language as a constitutive part, is a prerequisite for the definition of any change which is the aim of our common project. When analysing the process of transformation by a number of disciplines we expect to discover significant features of this alteration and the forces dominating it. The current highly complex present linguistic situation in the western and south-western fringe of the Chad Basin will be reconstructed from the historical migrations undertaken by the various linguistic groups from Lake Chad (mainly Chadic languages) to their present settlements. The six authors, the linguists Dr. Dimitr Ibriszimov, Dr. Doris Löhr, Christopher Mtaku, the ethno-musicologist Dr. Raimund Vogels, and the historian Ibrahim Maina Waziri integrated the results of their studies into one paper towards a systemic approach by tracing back the common roots of the languages, the customs and the music of those peoples and give an outline of their tradition concerning their movements. A basic dual model of migration will be put forward.

The architecture and chemistry of a dug-out: the Dufuna Canoe in ethno-archaeological perspective
(1996)
It is the intention of this paper to highlight the processes involved in the production of a dug-out. Two disciplines appear strikingly clear in the title of this paper; architecture and chemistry. It is deliberate, exhibiting the multifaceted approach to issues in archaeology. The Dufuna canoe, the main subject of the discussion, is entirely an organic material, long used by prehistoric populations, abandoned and covered in a huge deposit of earth, unearthed by the spade in two streams of excavations for the purpose of dating, measurements, documentation, which yielded a date of 8500 years as the oldest canoe in Africa and one of the oldest in the world. Who could have produced such an "artefact"? These and other related questions are fundamental towards the understanding of the history and society that lived in that environment in prehistory. Since we are dealing with a single "artefact" produced by prehistoric populations, long gone and extinct, we would not be in a position to reconstruct the processes of manufacture of the dug-out by any source other than by ethno-archaeological and ethnographic investigation and experiment of the contemporary society which manipulates similar environment with a view to stimulating the past mode of production. The method used in the data collection was by oral interviews and field observation.

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.

Our dichotomy of ‘nature’ and ‘culture’ is expressed in the Kanuri language with the terms al@ga for ‘creation’ and ‘creature’ which embraces trees, mammals, birds, insects, humans, in short the whole of the natural environment, and ada for ‘custom, habit, way of behaviour, family tradition’ for culture as a whole. There is no genre of oral literature, which would describe al@ga as such, but aspects of it can always be expressed in proverbs, riddles, toponymic praise phrases and songs, of which those performed by the hunters figure most prominently in reflecting upon al@ga. Yet, in these songs (and partly in other genres) ideas about al@ga are not purely descriptive in naturalists’ terms. They are much rather expressions, which centrally combine notions of the social and natural environment.

The paper presents a short introduction to the environmental factors, e.g. climate, geology, relief forms and soils of the study area in the southern parts of the Gongola Basin. The study area covers the high mountain range of the Tangale-Waja Uplands and the adjacent pediplain, following in the north. It is asked if the natural factors enforced former inhabitants of the area to develop special land use techniques like field terracing to ensure the essential crop production under insufficient geoecological conditions.

In the culture of the Pero, Longuda and Tula People in the south-eastern part of Bauchi State, north-eastern Nigeria, terraces are found as traditional means to improve the environmental condition and to secure the survival of the people. To classify those terraces according to their form and function, the techniques and customs of their building and the traditional structures of their development they have to be compared in the context of their own culture. The paper gives a few examples showing that the importance of terraces for the historic and religious concepts of the Pero, Longuda and Tula People is expressed through a tight network of oral traditions, social and religious customs and structures of belief and explanation, which, once they were woven together, eventually build what a malam from Tula called a glue of inheritance, identity, integrity, continuity and security.

The vast distribution of terraces in the geographical Sudan zone of West Africa leads to the question why and under which conditions an agrarian society might apply this particular form of farming. From an anthropologist's point of view it is essential to understand why farmers practise this form of farming and therefore try to explain the reason for it. The best way to gain insight is the description of terrace farming and when taking a closer look, we realize that farming is nowhere only an isolated agricultural activity.

Our paper deals with the problems of migration, culture and language in the wider Benue-Gongola basin. Here are mainly concerned the West-Chadic speaking groups Kwami, Kupto, Kushi and Piya as well as the Jukun who speak a language belonging to the Benue-Congo family. We try to point out the possible reasons for their historical migrations and in particular the consequences of ethnic expansion of the Jukun in the middle Benue region. History shows that contacts of ethnic groups - being peaceful or by force - had always led to mutual influences and changes in culture and language, which finally resulted in cultural fusion of various aspects. Our study, based mainly on oral traditions as well as on linguistic comparisons, focusses especially on the history of the above mentioned Chadic groups, who are considered - according to our hypothesis - to have come in close contact with the Jukun. Subsequently the warlike expansion of the Jukun caused a strong turmoil which led to the scattering of the various ethnic units.

With one group generally constituting the autochthonous host - representing the core population in the centre - immigrant groups tend to reside in separate ethnic wards and even work in wards/quartiers identified with their ethno-specific crafts and trades - and often named after them. The socio-lingustic survey will therefore use available and new maps and ethno-linguistic statistics: For the former, the urban surveys by the Max Lock Company of north-eastern Nigeria have been of great help, but have to be updated ; for the latter, various censuses had to be supplemented by more recent information . With ethno-linguistic wards constituting enclaves which can only interact through a language or languages in common, we can apply the general model of the triglottic configuration by positing x territorial and y immigrant, ethnic languages of solidarity; one general urban community language or lingua franca of interaction; and the official language of authority and administration. This language of authority was formerly a local aristolect (Kanuri or Fulfulde), but is now mostly an exolect - English or French. This short presentation concerns ongoing work in urban socio-lingustics developed in Maiduguri over some 15 years.

Changes in settlement pattern and culture - the process of down-hill migration in Tula, Bauchi State
(1996)
The process of down-hill migration of the Tula people started during the 1920s and has not yet finished. The resulting present situation might give information how far terraces play any role in the economy, ecology and ideology of the Tula. Approaching this question from a socio-agricultural point of view some facts which indicate the pertaining or overcoming of traditional structures will be presented. In the following the land tenure system, the adoption of innovations and the role of women in agriculture will be discussed comparatively for Tula Wange and Tula Baule on the plateau, Fantami, which is generated by down-hill dwellers of Tula Wange, with its more or less bad farming conditions on shallow sandy soils and Kaltin, where the down migrants of Tula Baule settle in a more fertile area. Tula Wange numbers around 2000 households, Baule 1000, Fantami about 200 and Kaltin 350 of which the sample survey includes 15% in the plateau sites and 25% in the plain settlements.

The mountains of the Tangale-Waja Uplands are inhabited by a number of small ethnic groups. They speak different languages which belong to two unrelated linguistic stocks. The Afroasiatic stock is represented by Chadic languages, especially Tangale, but also Pero and Kushi (further to the south along the slopes of the Muri Mountains) of the Bole-Tangale Group. But the majority of the languages belong to the Adamawa branch of the Niger-Congo stock. The study of the vocabulary, technical terms and expressions relating to farming in general and 'farming on terraces' in particular constitutes another important aspect of our multidisciplinary research project providing us with valuable information about the history of the settlements and cultures of the entire region. In this communication we will restrict ourselves to a few general observations which are mainly based on the comparison of selected items of the farming vocabularies of those communities which used to farm the slopes of the mountains in our research area. We want to focus on the various designations for "terraced farms" and "terraces" including any arrangement or setting of stones on farms to enhance and support the production of the staple food: guinea corn (sorghum) and/or millet (pennisetum).

The paper takes recourse to oral tradition and linguistics to ascertain the assertion that the presentday Kanuri and Kanembu speech forms emerged from the same parent language. In determining the parent language, the descriptions of the various components (i.e. clans and ethnic groups) of Kanuri and Kanembu are given as a first basis and the relation of each dialect of Kanuri and Kanembu to the other (i.e. dialect contiguity) is demonstrated as a second basis. Taking into consideration the sociolinguistic background of both Kanuri and Kanembu, the brief history of their divergence, the strong contention of the Borno Ulama and the dialect contiguity of the data presented, the paper concludes that Kanuri and Kanembu are initially one and the same language with ancient classical Kanembu being the parent language.

Two sites situated in the Sahelian and Sudanian zones of NE-Nigeria were chosen for pollen analysis. A sediment core from an interdunal depression in the eastern Manga Grassland provides information on the Holocene vegetation history of the Sahel between c. 9600-3400 B.P. The 3 m pollen record indicates an open savanna during the mid-Holocene. The presence of Sudano-Guinean taxa, which were mainly restricted to the interdunal depressions, points to more humid conditions. Already before c. 4000 B.P., a slow change towards drier conditions and the establishment of the modern Sahelian vegetation is visible in the diagram. This development was accompanied by high fire frequencies. A 16 m core from a crater lake (Lake Tilla) in the Sudanian zone of NE-Nigeria provides a pollen record which can be dated back to approximately 11-12000 B.P. Preliminary pollen spectra show a relatively constant pattern with a dominance of grass pollen even during the middle Holocene.

Maiduguri, an important city in the Sudano-Sahelian zone of West Africa, experiences both drought and floods. Although droughts are more popular, floods are a seasonal occurrence in parts of the city in the average rainy season. Both hazards exert a heavy toll on their victims. Present response to the hazard problems is characterised by a fire-fighting approach which does little about future occurrence. Much of the perception and response is spiritual and stops short of needed structural and organisational programmes for effective mitigation of hazards. Future occurrences of drought and flood may have more adverse effects as land use in the city becomes more complex and agricultural and water supply system comes to depend heavily on surfacial sources. Future effects will also depend on the socio-economic conditions of the people at risk and the capacity of those who help them. Governments and people need to work together to reduce drought and flood hazards.

This paper examines Borno's colonial economy with particular reference to the activity of indigenous traders. Stress is laid on trade within Borno and between the province and other markets in Nigeria and the adjoining colonies of Cameroon, Chad and Niger. An analysis of the involvement of traders, ranging from Kanuri, Hausa, Tubu, Fulani, Shuwa Arabs, Yoruba to Igbo, in items such as livestock, indigenous cloths of Hausaland manufacture (especially turkudi), kolanuts, local salt, natron, dried fish, imported cotton materials and salt is also attempted. Although Maiduguri (or Yerwa), Nguru, Potiskum, Bama, Goniri, Monguno, Geidam, Abadam and Biu were the main market centres in the province during much of the period under review, the activity of traders in Maiduguri is chosen for consideration in the paper. Apart from being the provincial and Shehu's capital, the emphasis on Maiduguri is informed by the town's commercial importance, especially in the overland trade between the rest of Nigeria and the neighbouring colonies of Cameroon, Chad and Niger.
