Shuwa-Arab economics: livestock management and animal consumption Augustin F.C. Holl Museum of Anthropology, Department of Anthropology, Center of AfroAmerican and African Studies, University of Michigan, Ann Arbor, USA Abst r a c t / Zu s a m me n fa s s u ng Shuwa-Arab communities reached the Chad basin in the late 14th century AD and from then on spread to their present day locations in the Chad republic, Cameroon, Niger, and Nigeria. The ethnoarchaeological research conducted on their settlements in the Houlouf region in northern Cameroon allowed for an interesting assessment of their patterns of subsistence, the importance of livestock in their daily life, as well as patterns of animal use and meat consumption. The taphonomic trajectories of faunal remains and their implications for the understanding of Shuwa-Arab economics are evaluated at three settlement types: permanent villages, semi-permanent villages, and dry season camps, sampled during three separate seasons of fieldwork. Shuwa-Araber Gemeinschaften erreichten das Tschadbecken im späten 14. Jahrhundert AD. Von dort aus breiteten sie sich zu ihren heutigen Ansiedlungen in Tschad, Kamerun, Niger und Nigeria aus. Die an ihren Fundplätzen in der Houloufregion Nordkameruns durchgeführten ethnoarchäologischen Untersuchungen ermöglichen eine interessante Einschätzung hinsichtlich Subsistenzmuster, Bedeutung von Vieh im Alltag sowie Nutzung von Tieren und Fleischverzehr. Die taphonomischen Prozesse denen Tierreste unterworfen sind, sowie deren Konsequenzen für das Verständnis der Wirtschaft der Shuwa-Araber werden anhand von drei Siedlungstypen evaluiert, nämlich Dörfern mit dauerhafter Bewohnung, Dörfern mit semi-permanenter Bewohnung und Trockenzeitlagern, deren Beprobung während dreier Geländeaufenthalte stattfand.

Many are now fully sedentary, relying more on agriculture than livestock husbandry. Others remain fully semi-nomadic, residing one part of the year in their main rainy season villages, while spending the dry season in camps that can be located as far as 150 kilometers away. Relationships to neighboring communities, the inhabitants of which are predominantly sedentary and employ agricultural and fishing subsistence strategies, are very complex (Holl 2003). They range from partnership to rivalry, articulated on unequal power relationships. Even if they are sedentary and rely more on agricultural products, the management of livestock and the handling of animal resources are what set the Shuwa-Arab apart in the Chadian plain ethnic mosaic (Podlewski 1966, 1971, Lebeuf 1969, 1987, Zeltner 1970, 1979, 1980, 1988, Conte & Hagenburger-Sacripanti 1977, Hagenburger-Sacripanti 1977a, b, Frantz 1981, Tijani 1986, Holl & Levy 1993). How are their socio-economic systems organized? How do they manage their livestock resources? And what patterns of consumption of animal resources did they develop? These are the key issues addressed in this paper. The investigation of settlement structures and patterns of subsistence in contemporary societies is one of the success stories of ethnoarchaeological research (Yellen 1977, Binford 1978, Hodder 1982, Atherton 1983, Agorsah 1985, 1990, David & Kramer 2001, Holl 2003). This kind of research analyzes the patterns emerging from residual regional settlements. Despite the dominant optimism, the retrodiction of ethnoarchaeological findings to past archaeological situations is severely handicapped by significant differences in scale. If ethnoarchaeology has any impact on archaeological research beside the obvious situation of documented historical and cultural continu- 38 Augustin F.C. Holl Fig. 1: Map of the study area ity, it is through its role as a “hypotheses generator”. Ethnoarchaeology does not solve historical problems. It provides a series of hypotheses that can help make sense of the archaeological record at hand (Holl 2003). This iconoclastic position is not shared by most Africanist ethnoarchaeologists despite its obvious accuracy, as shown in the analysis to follow. or Syria, used Egypt only as a corridor to the west or the south; others remained for a shorter or longer time. Being notoriously anarchic, turbulent and always in opposition to any outside control, they represented an element of danger and unrest, too often causing disruption of economic life by their raids on villages or by holding up caravans” (Hrbek 1977: 69). Short Historical Background The Mameluk dynasty of Egypt launched a number of heavy military campaigns against Arab mobile pastoralists and forced many out of the Nile valley. These groups moved west, and spread slowly to reach the Chad basin in the 14th century AD. They adapted to a broad range of social and political circumstances, as part of the elite in some cases and as pariahs in others (Zeltner 1970, 1979, Garcin 1985, Bianquis 1990, Holl & Levy 1993, Holl 2003). From the 10th to the 14th century, the territories situated between the Nile and northern Darfur were settled by Arabs (MacMichael 1922). Their changing adaptation to their new ecological and cultural settings generated a great deal of regional variations outlined by Hrbek (1977). Those settled along the northeastern part of the territorial range continued to rear camels and sheep. They consist of different clans of various tribes but nonetheless formed large groups known as the Kababish (from Kabsh i.e. “ram”). Those who migrated further south, to southern Darfur, southern Kordufan, and westwards to Wadday and the Lake Chad region, adopted cattle husbandry and became known as Baqqara (from Baqara i.e. “cow”). “Although they preserved their nomadic way of life and their tribal system intact, they intermarried with the local peoples, Shuwa-Arab communities started to settle in the eastern confines of the Chad basin at the end of the 14th century AD. Their arrival in that part of Central Sudan was the result of long and protracted migratory histories that took their ancestors from their Arabian homeland to the Nile delta in the 7th century (Hasan 1973, Fisher 1975, 1977, Hiskett 1976, 1994, Hrbek 1977, Garcin 1985, Bianquis 1990). The ancestors of presentday Shuwa-Arab were among the first Arab tribes to settle in Egypt after its conquest by Moslem troops. Some of these groups decided to stick to their traditional way of life, that of mobile pastoralists. Suspicious and resentful of centralized bureaucratic organizations, they gradually trickled southwards along the Nile River and, step by step, interacted with and later disturbed a number of Nubian Christian kingdoms. The then city-centric and dominant view of these groups is well captured in the following excerpt: “On the fringes of the cultivated lands and beyond them roamed Arab nomad tribes not yet assimilated to a settled life. Some of these tribes coming from Arabia Shuwa-Arab economics: livestock management and animal consumption 39 Fig. 2: Cattle herd grazing in the arbustive savanna. Fig. 3: Prime grazing from the yaere, the hinterland depression. inaugurating thus another process, that of the gradual Africanization of the Sudanese Arabs” (MacMichael 1922, Cunnison 1966, Hasan 1973, Hrbek 1977: 79, Kropacek 1985). In the Chad basin, Shuwa-Arab communities were spread out between the Darfur and Lake Chad (Denham et al. 1828, Barth 1965, Lebeuf 1969, 1987, Lange 1987, Nachtigal 1987a, b), in Wadday, Bagirmi, Bornu and many others local chiefdoms. T he d at a ba se The material analyzed in this article was collected in the Houlouf region, officially known as the El-Birke Can- ton, in three field seasons, in 1987, 1989, and 1991. The study area is located along the southern margins of the Sahel in northern Cameroon and measures 500 square kilometers, 25 kilometers W-E and 20 N-S, at 11° 55’/12° 05’ latitude north and 14° 50’/ 15° 05’ longitude west. The western, northern, and southern boundaries of the study area are arbitrary. The eastern one corresponds to the sinuous course of the Logon River (Fig. 1). The land, generally flooded during the rainy season, is flat with elevation ranging from 296 to 290 m above sea level. The vegetation consists of an arbustive savanna, with thorny trees and shrubs (Fig. 2) and extensive grasslands, prime grazing land for herders (Fig. 3). A number of settlements, ranging across the local sites’ spectrum, 40 Augustin F.C. Holl Fig. 4: Map of Djidat II, a permanent settlement. were sampled in different parts of the study area. The studied settlement sample thus consists of four permanent villages: Abuzrega, Djidat I, Djidat II (Figs. 1 and 4) and Marafin, all located on land generally above the average flood level; 11 dry season camps arranged in two clusters (Fig. 5) (Amachita and Agedipse) located in the hinterland depression (Yaere); and finally, 12 semipermanent villages, distributed all over the study area (Fig. 6). Some of the members of the research crew of Shuwa-Arab ethnic background were very familiar with all the aspects of life in these different kinds of settlements. Permanent and semi-permanent were constant features of the cultural landscape. Dry season camps on the other hand were never set by the same group on the same spot from one year to the next. Even the pattern of association that resulted in dry-season camps clusters was in a constant state of flux. Pat t e r n s of subsist e nce In all the cases, Shuwa-Arab subsistence systems include grain agriculture and livestock husbandry. But the balance in terms of labor investment and social values varies according to local situations and historical circumstances. A third element, fishing, can be added to that fundamental pair, but its position within the systems is slightly ambiguous as most of the catches are sold in town markets as sun-dried fish. Fish is nonetheless an important component of the Shuwa-Arab diet. Fishing In the study area, fishing is a strictly seasonal activity confined to the flood period (September–November) when the hinterland depression – Yaere – is trans- Shuwa-Arab economics: livestock management and animal consumption 41 Fig. 5: Map of Amachita V (Yaere V), a dry-season camp. formed into an extensive water body. The productivity of fishing expeditions that settled in camps on available higher grounds is however low at the peak of the floodperiod because of the high dispersion of fish populations. It is higher at the onset of the flood and during the receding phase (Blache & Miton 1962, Blache 1964, Laure 1974). Different tools are part of the fishermen gear; they include dug-outs, nets, basket-traps, batteries of fish hooks, as well as a range of cutting tools. Fishing parties generally consist of young adult males. They settled in fishing camps for several weeks in a row during the optimal season and process their catches on a daily basis. Two complementary techniques are used, sun-drying on the one hand for small size fish, and smoking for the larger specimens on the other hand. Sun-drying on a woven reed mat does not require special installations. It is as such archaeologically invisible. Smoking is performed in especially built struc- 42 Augustin F.C. Holl Fig. 6: Map of Ngada I, a semi-permanent settlement. tures. The examples recorded near the Amachita camp cluster, situated on a low archaeological mound (Holl 2002), are elongated and horse-shoe shaped. They consist of a low mud-wall 0.20 to 0.30 m in height. Wood twigs are placed on top of the substructure, and the fish to be smoked is laid out flat upon this constructed surface. The hollow space within the structure and underneath the platform is filled with slow burning fuel suited for producing thick smoke, generally a combination of almost dry and moist wood, leaves and grass. Depending on the size of the catch, quantities of both sun-dried and smoked fish are transported to the markets of the nearby cities of Kusseri and Ndjamena, or the entire product is stored in the camp in especially dug clay lined pits for the whole two-month fishing season for sale at a later date. Agriculture All the communities from the study area are involved one way or the other in agricultural production. However, the levels of involvement vary from one set of groups to another, within and across ethnic affiliations. As far as the Shuwa-Arabs are concerned, this involvement is minimal for some of the groups inhabiting semi-permanent villages. It is much more important for those living in permanent settlements. The documented agricultural activities are divided into two main components. Grain agriculture devoted to the cultiva- tion of sorghum and maize for the production of the staple food on the one hand, and on the other, intensive gardening geared toward the production of green vegetables (lettuces, cucumbers, and tomatoes) sold in the markets of nearby towns. Intensive gardening is carried out during the first half of the dry season. It is a labor-intensive process involving the frequent watering of carefully designed green vegetables plots. The production of green vegetables generally starts with the receding of the flood and lasts as long as the water-table is high enough to allow optimal access to water. The gardens are located along the northern edge of the Yaere, approximately one kilometer south of the settlement of Madaf. It is predominantly a young adult male activity from which they raise some cash. Plots are owned by individuals, close kin or friends, and labor-cooperation seems to be minimal. Finally, beside its cash value, the contribution of intensive gardening to the villagers’ diets is negligible. The bulk of agricultural production revolves around the cultivation of sorghum and maize. Red sorghum is preferentially cultivated by the inhabitants of semipermanent settlements. They provide some explanations for their choice: 1) red sorghum growth and maturation cycle is shorter; consequently, it can be sown after the beginning of the receding flood and harvested Shuwa-Arab economics: livestock management and animal consumption just in time for the move to the dry season camping area. 2) It does not attract birds; the amount of loss to natural competitors is minimal. 3) It is tastier and much more nutritious. White sorghum is preferentially grown by the inhabitants of permanent villages. Its out-put per acreage is higher but it is the favorite target of birds. Different bird-scaring devices are developed to protect the harvest. They include classic scarecrows, noisemaking devices, as well as the active involvement of children stationed on elevated platforms with their slingshots made of two parallel rubber bands tied to a Y-shape handle. The proportion of maize in the local agricultural output is still minute; Bilbede appears to be an interesting case of shift from sorghum to maize production if judged from the large amount of corncobs found in the site. There are no differences in tools and field preparation techniques used in the cultivation of either red and white sorghum or maize. In most cases, settlements are surrounded by one or more rings of fenced cultivated plots. This is not the case for Danguerchem, Gobrem, and Ngumati. All these sites were abandoned at the time of fieldwork; the absence of evidence for cultivated plots is certainly due to poor preservation. Ndom has six fenced fields for six households, ranging in size from 65 x 30 m for the largest to 30 x 25 m for the smallest. The situation is radically different for permanent settlements. All are surrounded by several rings of cultivated fields. Mishiskwa is located on a shallow mound; the rings of fenced fields are not attached to the rest of the village features. They are also comparatively narrow, stretched on less than 500 m outwards. Abuzrega, Djidat I, Djidat II, and Marafin have more complex catchment areas stretched on a radius of two to three kilometers. In fact, the whole central-western part of the study area has a dense pattern of dendritic field systems visible on low altitude aerial photographs. The shift toward heavier reliance on agricultural production, already suggested with the relatively high frequency of storage platforms, is clearly visible in the landscape. The remaining settlements present more diverse situations as far as the nature, distribution, and size of cultivated fields are concerned. The frequency of cultivated plots per site varies from 10 (Bilbede) to 2 (Bawara). There are three settlements, Bawara, Ngada II, and Ngada I, with two to four cultivated plots. In the first site with two fields for seven household units, the recorded plots measure 48 x 37 m for the larger specimen, and 17 x 14 m for the smaller. At Ngada II, the second with three fields for eight household units, two of the cultivated plots measuring 40 x 30 m for the larger and 15 x 12 m for the smaller are devoted to sorghum, and the last one 25 x 17 m to maize. And finally, at Ngada I, the third site with four plots for nine household units, two of the largest plots, measuring 22-23 x 25 m, are devoted to the cultivation of gourds for calabashes used as canteens and other containers and a kind of 43 herbal tea. The smaller plots measuring 20 x 18 m and 15 x 7 m are sorghum fields. Bilbede, Gallis, Ngada III, and Ngada IV have six to ten cultivated plots. Gallis has six fields for nine household units, ranging in size from 58 x 40 m for the largest specimen to 28 x 25 m for the smallest one. Both Ngada III and Ngada IV have nine fields each for fourteen and twelve household units, respectively. In the former, the largest cultivated plot measures 44 x 34 m and the smallest 13 x 10 m. In the latter, they measure 37 x 25 m and 20 x 13 m, respectively. Finally, Bilbede has the highest number of cultivated plots, ten for nine household units, as well as a relatively large threshing area. They vary in size from 60 x 40 m for the largest to 16 x 16 m for the smallest. If measured by the number of documented cultivated plots, the extent to which the inhabitants of these last settlements are engaged in agriculture appears to be extremely variable. Because the number of cultivated fields is systematically lower than the number of documented household units, some family groups may have pooled their plots or, quite unlikely, relied on exchange for their supply of agricultural products. Pat t e r n s of spa ce allo cat ion The multiple needs of livestock in terms of fodder, water, and protection are embedded in Shuwa-Arab settlement layout. Evidence for livestock husbandry is found at all the tested settlements. Their nature, characteristics, and frequency vary from village to village. However, they generally include cattle corrals, sheep/goat pens, livestock houses, tethering as well as milking poles, and milking stations. The number and distribution of these features, in dry season camps, semi-permanent, and permanent villages, are a good indication of the important role livestock play in the lives of site inhabitants. The differential allocation of space to human habitation stricto-sensu versus livestock provides interesting insights (Table 1). Livestock space takes the largest proportion of dry season camps, varying from 684 (Amachita V) to 2,344.35 m2 (Agedipse III). The human space on the other hand ranges from 162.19 (Agedipse II) to 656.70 (Agedipse III) m2. There are three main situations if human space is factored to that of livestock: 1) lower values [0 to 1] mark a strong predominance of livestock space in the site’s layout, the lower the figure, the larger the difference. 2) The value <1> points to a well balanced allocation with equal share of the site’s space devoted to human habitation and livestock management. 3) Higher values [> 1] mark the predominance of human habitation stricto-sensu in the site’s layout. Livestock is an essential element in the spatial layout of all Shuwa-Arab settlements. However, things appear to be tailored differentially as each of the three settlements categories stands out. 44 The value recorded from dry season camps varies from 0.09 (Amachita IV) to 0.38 (Amachita V) indicating quite clearly that these localities can safely be also called livestock camps (Table 1). The figures for semipermanent settlements that range from 0.12 (Bawara) to 1.04 (Gallis) cover two trends. The first, indicated by values ranging from 0.12 to 0.31, documented at Bawara, Gobrem, Mishiskwa, and Ndom (Table 1), is characterized by a layout of features typical for an overall communal management of livestock herds. The other, with values varying from 0.43 to 1.04, found at Bilbede, Danguerchem, Gallis, Ngada I, II, III, IV, and Ngumati, points to a shift toward a less communal and more individualized household management strategy. This is visibly manifested by an increased reliance on fences. Agriculture and other economic activities such as raising poultry play more important roles in these settlements. Permanent settlements present a totally different but not surprising situation (Table 1). A larger proportion of the built space is allocated to human habitation but the share of livestock is very important, ranging from 1,010.90 (Djidat I) to 4,051.11 (Djidat II) m2. The tabulated values vary from 1.13 (Djidat II) to 2.09 (Djidat I). This trend does not point to a decreasing importance of livestock in the settlement economies. In this case, livestock management is exclusively a household affair. Each extended family has its own cattle enclosures, sheep/goat pens, and livestock houses. A closer look at the distribution of features built for livestock provides additional insight into intra- and inter-site variations. These features essentially belong to three categories, relatively large size corrals for cattle, smaller pens for sheep/goats, and houses for both cattle and sheep/goat (Table 2). Dry season camps and semi-permanent settlements exhibit strong similarities in the frequency distribution of cattle corrals and sheep/goat pens. The number of corrals varies from 1 to 4 and that of sheep/ goat pens from 1 to 10. There is, however, a significant difference in the number of livestock houses which ranges from 1 to 5 in the dry season camps and from 2 to 24 in the semi-permanent villages. The term livestock house is somewhat ambiguous since in the dry season camp context most of these houses are used for horses. The relatively large number of livestock houses in semi-permanent settlements – rainy season villages – is partly correlated to the local tse-tse fly infestation that generally peaks during the rainy season and the ensuing annual flood. During that time of the year, cattle herds are kept and fed indoors throughout the day and taken out for watering at nightfall. The unusually small number of livestock houses (2) at Danguerchem is to some extent due to the poor preservation of the settlement record. It is very likely that there were many more livestock houses than detected during the mapping of the site (Table 2). As far as permanent settlements are concerned, the frequency distribution of livestock features alone is misleading. The number of cattle corrals varies Augustin F.C. Holl from 2 to 5 but they are generally smaller in size and each belongs to a specific household. The number of sheep/goat pens, which ranges from 4 to 10, is surprisingly low if compared to the settlements’ population size. Finally, the number of livestock houses mirrors that of semi-permanent settlements for the same reasons. Chicken coops and straw storage platforms complement the range of features used for the management of livestock. A few chicken coops are found in dry season camps (Table 2), but they are particularly concentrated at two sites, Bilbede and Ngada IV. The implication of this pattern will be discussed later as it represents a trend toward specialization and intensification. In summary and from the perspective of settlements’ constructed features, it is not an exaggeration to suggest that livestock needs are the crucial element placing constraints on the size and shape of Shuwa-Arab settlements. A s s e s si ng l ive st o ck u se A more straightforward archaeological approach to the analysis of subsistence patterns is adopted in this portion of the paper. Faunal samples have always played an important if not ambiguous role in the identification of past socio-economic systems (Cribb 1991, Sadr 1991, Smith 1992). “Traditionally, sites with a predominance of domestic animals in the faunal remains have been attributed to pastoralists. In some instances, researchers have tried to go further, to infer milk, meat, or wool production from the age and sex profile of the domestic animal remains. … But faunal samples, so easily distorted by taphonomic processes, are rarely representative enough to allow such studies. … Furthermore, most interpretations of animal mortality curves are based on a tentative model. The validity of which has been challenged” (Sadr 1991: 13). Sadr’s critique of faunal remains analyses is important and hits the nail on its head. The vagaries of taphonomy and the hazards of preservation and recovery make an accurate assessment of livestock management systems extremely difficult despite the optimistic promises of age/sex curves. The state of preservation of the archaeological record at hand and the degree of resolution of the determination of the collected remains can nonetheless lead to interesting interpretations of past management of animal resources. As sound as it is, Sadr’s critique is unfortunately not backed by any useful suggestion on how to extract good information from archaeological faunal samples, and one is tempted to ask, what to do? As will be shown in this analysis, even an ethnoarchaeological study of single occupation sites like the Yaere dry season camps does not provide an easy and ready to generalize answer.

The faunal samples considered in this discussion were systematically collected from the semi-permanent sites and dry season camps within the confines of each of the investigated settlements. The sampling space was delimited by the outer perimeter of houses. Visible animal bones were handpicked by a crew of fifteen workers, walking in parallel lines with each covering a two meter wide transect. It was thus possible to collect the maximum of the accessible faunal material. The sampling techniques used in this case favour large bones (Fig. 7). Not surprisingly, and despite the well-known high consumption of fish among Shuwa-Arab from the study area, fish bones are literally absent from the collected 46 Settlement Augustin F.C.

All bones scattered over the sites’ surface or in their immediate periphery are not necessarily refuse from human meat consumption. Some result from the scattering out of skeletal elements of dead animals. Other are dispersed and/or accumulated by dogs, jackals, and other scavengers. Two dense bones scatters were found and mapped. One was discovered at few hundred meters east of Gobrem, on the right bank of the Abani, a seasonal stream, and the other less than one hundred meters south of Ngada IV. The bones collected from the studied sites had to be identified and recorded directly in the field, a task carried out by Dr. Anne Bridault and myself (Holl et al. 1991). For understandable reasons, these bones were not intended to be brought back to the university laboratory. The material collected from each site was arranged directly on the ground into anatomic elements, species, and size. This tactic allowed for an immediate visual assessment of the overall distribution and frequency of anatomic elements, as well as the range of species represented (Fig. 7). Shuwa-Arab economics: livestock management and animal consumption 47 Fig. 7: Sample of animal bones collected from Ngada I T he b one s c at t e r s Ngada IV bone scatter The bones’ scatter from Ngada IV consists of the carcass of a calf that died two years prior to the 1989 fieldseason. The cause of death was not made explicit to the field crew. The bulk of the calf remains, also comprising most of the bones, are contained within a dry and parched skin. With the exception of three goat scapulas, all the remaining 128 mapped bones resulted from the dismemberment and dispersal of the calf’s skeleton by dogs. Gnaw marks were found on a left patella. Limbs bones, skull bones, cervical as well as portions of lumbar vertebras were found widely scattered around the ribcage which was still preserved in the dried skin. The set of processes leading to the formation of the bone scatter described is clear. Initially, a dead calf was abandoned at some distance from the village, although it is not known if the young animal died in the village with the carcass being transported later to an acceptable distance from the settlement, or if this happened at the location where it was found. This was followed by scavenging domestic dogs, rarely fed in the African countryside, which took the opportunity to feed on the available meat. This functioned to scatter most of the limb bones away from the axial skeleton, and at the same time bringing in few sheep-goat bones. The bone scatter is comprised exclusively of domestic animals remains; it does not, however, provide any crucial information on the settlement-subsistence status of the village inhabitants. Alone, it does not help discriminate between a dry season camp, a semi-permanent village, and a permanent settlement. Gobrem bone scatter The Gobrem bone scatters are in fact located on the “ghost” of a completely eroded twin settlement that was situated on the right bank of the Abani seasonal stream. It is spread over 395.20 m2 and divided into four subcomponents termed bone scatter (BS) I to IV. All the 237 recorded bones belong to cattle, with the density varying from 0.75/ m2 to 0.38/ m2. BS-I is found at the northwestern end of the grid sample. It contains 76 bones, 28 from the appendicular and 48 from the axial skeleton. Jaws and cranium bones are rare with two cases of left and right mandibles, the latter with a fully erupted M3. Two individuals are represented in the studied sample, a mature and a juvenile animal. All anatomical elements, from head to hooves are represented, suggesting that both animals were probably discarded, with the carcasses later being fed upon by domestic dogs and scavengers like golden jackals. 15 bones out of a total of 76 present evidence of gnawing by carnivores. Interestingly enough, all the bones with gnaw marks belong to the axial skeleton: cervical, thoracic, and lumbar vertebras, suggesting late access to the carcass. This is generally the case when an animal dies during the flood season in a river bed, with the carcass accessible later after the receding of water. BS-II is located at few meters southeast of BS-I. 94 cattle bones were recorded, 49 from the 48 axial skeleton, and 45 from the limbs. Gnaw marks are documented on 30 out of 94 bones. Most of these marks are found on vertebras, mandibles and cranial bones. However, 5 limbs bones, scapula, pelvis, tibia, and tarsal bones were found with tooth marks. BS-III is located thirteen meters southeast of BS-II. The recording grid measures 10 m in length and 8 m in width. 31 cattle bones have been mapped. 22 belong to the axial and 9 to the appendicular skeleton. The sample represents a single individual with gnaw marks found on five bones, the proximal end of the left and right femurs, both the left and right side of the pelvis, and lateral portions of the sacrum. The pattern of tooth marks suggests the scavenger fed on the upper part of the rear limbs. Finally, the remaining sub-component BS-IV is spread over 91.20 m2 east of the three previous ones. It measures 15.20 m in length and 6 m in width and includes 36 cattle bones, 20 from the axial skeleton and 12 from the limbs. The scatter seems to be comprised of the skeleton of two individuals. In order to clarify that issue, the sampled area was divided into four equal units, quadrant I to IV (Q-I to Q-IV). Ten bones were recorded from Q-I; they include the sacrum, which is gnawed on its edge, two left scapulas both with gnaw marks, one proximal and one distal femur, a left humerus, one specimen each of cervical, thoracic, and lumbar vertebras, and finally, a right pelvic fragment. The subset consists of elements of the upper limbs and backbone; with gnaw marks found on seven out of ten bones. Ten bones have also been recorded in Q-II; there are four vertebras, one cervical and three thoracic; two proximal ends of ribs, a left proximal femur, a right proximal humerus, and two tarsals. Five of the bones have gnaw marks. Q-III has seven bones, this time with a complete cranium of a young mature ox with well preserved horn-cores. Interestingly, the specimen has extensive gnaw marks, and the dried feces of a jackal were found on the cranium. The rest of the sample includes a left ulna, a right proximal humerus, a left distal femur, a cervical vertebra, a rib fragment, and a tarsal bone. Gnaw marks are rare on the rest of the sample, suggesting the scavenger focused on the cranium. Finally, Q-IV, containing nine bones, mostly includes elements of the axial skeleton. There are four vertebras, three cervical and one lumbar, two mandibles, left and right, one left proximal femur, one scapula blade, and a tarsal bone. Gnaw marks are found on two bones, the scapula blade and the lumbar vertebra. The Gobrem bone scatters appear to have resulted from the dismemberment of dead animals by scavengers. In both Ngada IV and Gobrem cases, there is no human contribution to the scatter of domestic animals bones described above. The strong predominance of cattle can easily lead any archaeologist to rightly infer the existence of a livestock husbandry. But the material at hand does not allow further clarification. Augustin F.C. Holl Fau n a l r e m a i n s f rom s e m ip e r m a ne nt set tle me nt s Faunal remains were collected in semi-permanent settlements and dry season camps. The relatively higher density of occupation and the ensuing higher degree of trampling precluded any significant bone sampling from the permanent villages. The total amount of bones collected varies considerably from one semi-permanent settlement to the other, ranging from 7 (Danguerchem) to 795 (Gallis) (Table 3). The proportion of undetermined splinters is high in general, varying from 4 (Danguerchem) to 275 (Ngada III). The recorded faunal remains are distributed into two major categories, domestic and wild animals (Table 3). Three wild animals species, gazelle, elephant, and hare, are represented in small proportions at Bawara, Gallis and Ndom (Table 3). Despite the well known importance of fish in Shuwa-Arab subsistence and economy (Holl 2003), they are practically absent in the material record with the exception of a single fish bone found at Ngada I. Domestic animals are partitioned into two sub-categories. One includes all animals used for direct subsistence purposes including cattle, sheep/goat, poultry, and other bovidae. The other is made of non-food animals like horse, donkey, and dogs, the bones of which were probably spread all over the sites by dogs and other scavengers. Horses are prestigious riding animals owned by few individuals. In this sub-category, the relatively large predominance of donkey bones is an accurate reflection of the importance this animal species has in Shuwa-Arab life. Donkeys are used to carry people and a broad range of loads in a multiplicity of situations. In all the recorded cases, cattle bones are predominant, conveying an accurate picture the Shuwa-Arab animal species hierarchy (Table 3). Sheep and goats are always in second position in all the tested settlements. A number of settlements present particularly interesting developments. The bone sample from Bilbede, with a relatively important proportion of chicken skeletal remains, confirms the impression gained from the observed high frequency of chicken coops (Table 3, Fig. 8). Chicken bones amount to 18 remains representing 3% of the sample. Cattle is largely predominant with 174 pieces (29.2%), followed by Bovidae sp. with 84 (14.1%), and sheep/goat with 55 (9.2%). Horse and donkey are represented by 1 (0.2%) and 4 (0.6%) bones, and unspecified equids by 14 (2.3%). The Ngada site cluster presents the broadest range of variation in terms of represented taxa (Table 3, Fig. 9). The recorded faunal spectra range from six (Ngada III and Ngada IV) to eight taxa (Ngada I and Ngada II). Despite the persistent predominance of cattle with proportions varying from 40.6% to 27.2%, each of the settlements has a specific combination of species. In addition to the 150 (27.2%) cattle remains, the Ngada I sample includes 76 (13.2%) Bovidae sp., 61 (11%) Shuwa-Arab economics: livestock management and animal consumption Fig. 8: The faunal spectrum from Bilbede.

Ngada II has the largest proportion of chicken bones with 20 (5.6%) remains as well as those from domestic dogs. The rest of the sample consists of cattle (98, 27.4%), Bovidae sp, (54, 15.1%), sheep/goat (29, 8.1%), donkey (9, 2.5%), and finally, horse and Equus sp. (7, 1.9% each). In addition to the standard domestic animals, which is strongly dominated by cattle with 210 (34.6%) skeletal remains, the Ngada III sample includes only a few chicken bones (5, 0.8%). Finally, Ngada IV has a handful of dog remains, with 3 (0.6%) bones. The rest of the sample with cattle largely predominant (185, 40.6%) is divided into sheep/goat, Bovidae sp., donkey, and Equus sp., with the proportion varying from 10.1% to 0.6%. Fau n a l r e m a i n s f rom t he d r y sea son ca mps The dry season camps sampled in this study were inhabited for two to three months – March – May/June in 1990. An important precipitation deficit in the 1990 rainy season allowed for an excellent preservation of these camps. They were not flooded that year as is generally the case. At first glance, the faunal remains collected from the sampled dry season camps provide a desperately monotonous picture of the represented faunal spectra. They are nonetheless the most accurate indication of pastoralism. However, a closer look at the evidence reveals interesting taphonomic differences and patterns of meat consumption during that part of the year. In general, the samples are small with frequency varying from a maximum of 65 at Amachita VI 1 - - Wild animals Gazella sp.

Two species, cattle and sheep/goat are represented, with a few specimens of land snail shells. The Limicolaria sp. shells recorded are not food refuse. They result from the natural death of land snails that fed on the camp’s refuse. The short term occupation and the small size of all the collected samples offer the opportunity to address interesting issues revolving around the management of animal products. The represented body parts and relative age of the animals can be used to tackle this issue. A m a ch it a c a mps clu st e r In the Amachita camp cluster, the amount of collected faunal remains varies from 65 (Amachita VI) to 15 (Amachita V). Land snail shells are more frequent ranging from two to six specimens. A single donkey bone was found at Amachita III. Amachita I is a four household camp inhabited by people from Djidat. The faunal material includes 3 cattle and 55 sheep/goat bones (Table 4). All cattle bones belong to an adult animal represented by two mesial humerus fragments and a scapula. It is clearly part of a share of meat chopped from the animal’s upper front limb and brought to the dry season camp. The rest of the sample consists of goat bones. They are partitioned into 3 cranium fragments with horn-cores, 6 jawbone fragments, 11 ribs, and a set of bones representing the lower limbs. They include two distal ends of tibiae, one belonging to a younger animal, three tarsal bones, and an ulna fragment. And finally, 29 chopped bones. With the exception of one tibia fragment, all the goat bones belong to adult animals. The striking absence of vertebras and upper limb bones indicates that these animals were not butchered in-situ during the occupation of the camps, it rather suggests that sun-dried goat meat was brought to the camp. Amachita II, with six household units, was settled by the families from Magourde, a village located 8-10 kilometers NE of the Yaere. The animal bone sample consists of 56 remains, 27 from cattle, 7 from goat, and 2 land snail shells, as well as 20 undetermined pieces (Table 4). The goat bones recorded include one cranium, four jaws, a left pelvic fragment, and a distal tibia with the astragal still attached. A large proportion of the cattle bones recorded, 20 out of 27, belong to calves. They are comprised of 4 crania, three of them hornless, 4 right and 3 left mandibles, 2 pelvic fragments, 1 right scapula, 1 right and 2 left humeri, 1 right radioulna, 1 right tibia, and 1 left metacarpal. The presence of a sacrum fragment with an attached left pelvis half suggests that at least one of the calf carcasses was not butchered. The bones of this individual were scattered after death and abandonment. Adult cattle are represented by two radio-ulnae (right and left), two metacarpals (right and left), and finally, a complete right hindlimb with the femur, tibia, calcaneum, and astragal, in Shuwa-Arab economics: livestock management and animal consumption anatomic connection. This set of bones also suggests the adult animal skeleton was scattered after death and abandonment. Paradoxically, the cattle bones from Amachita II do not seem to stem from meat consumption, and are more likely from the post-abandonment scattering of dead animal bones. Amachita III is an eight household unit camp settled by people from Chouaram. The faunal sample includes eight undetermined fragments, 2 Limicolaria sp. shells, a donkey tertiary phalanx, as well as 24 cattle and 11 sheep/goat bones (Table 4). Seven of the cattle bones are from calves. They are distributed into: 1 cranium, 1 cranial fragment, 1 jawbone, 1 jawbone fragment, 1 radius, 1 right tibia, and 1 metacarpal. Adult cattle bones are comprised of: 1 right horn-core, 2 molar teeth, 1 cervical vertebra, and 2 pelvic fragments, 1 proximal femur, 1 right radio-ulna, 2 distal radio-ulna, 1 right tibia, 4 carpals, and finally, 1 astragal and 1 tarsal. The uncovered goat remains belong to an adult animal that appears to have been butchered. They consist of 1 cranium and 1 cranial fragment, 1 molar, 1 rib fragment, 1 sacrum fragment, 2 humeri (left and right), 2 radio-ulnae (left and right), 1 mandible, and 1 proximal metacarpal. The faunal assemblage thus seems to be comprised of the remains of three animals, one calf, one adult ox, and one goat. Amachita IV, a nine household unit camp, was settled by families from Bam-Kala. The collected faunal material consists of 57 pieces made up of 6 Limicolaria sp. shells, 14 sheep/goat bones and 37 cattle bones (Table 4). The goat bones belong to a single adult animal and consist of 4 ribs, 1 complete and 2 mandible fragments, 1 cranium, and 6 fragments. Cattle bones belong predominantly to calves with 29 pieces out of a total of 37. Adult cattle are represented by lower limbs bones, 1 proximal ulna, and 7 phalanxes, 5 primary, 1 secondary, and 1 tertiary. Calves are represented by three complete skulls, 1 occipital bone, 1 complete vertebral column from the atlas to the sacrum, 1 ear bone, 2 mandibles (left and right), 4 jaw fragments, and 1 molar for the axial skeleton. The limb bones include 1 complete and 5 mesial portions of humeri, 1 left femur, 1 radioulna, 1 left tibia, 2 complete and 2 proximal ends of metacarpals, and 3 metatarsals. The presence of a complete vertebral column strongly suggests that the bones of at least one of the calves were scattered after it died. The adult cattle bones as well as those from the goat are more likely to represent food refuse. Amachita V is a seven-household unit camp. The amount of animal bone remains collected from the site is surprisingly small, with a total of 15 pieces divided into 2 land snail shells, 3 sheep/goat and 10 cattle bones (Table 4). Sheep/goat bones are limited to 2 ribs and one femur from an adult animal. Two individuals, one adult and a calf, are represented among the cattle remains. 53 One skull fragment, 1 molar, and 1 second phalanx belong to a calf, with the adult’s bones consisting of 3 fragments and 1 distal end from a humerus, and 2 proximal and 1 distal ends of radius. The eclectic representation of anatomic elements seems to suggest that the Amachita V faunal remains probably resulted from food consumption. Amachita VI was settled by eight families from the semi-permanent village of Alaya I. The faunal sample collected from the camp is comprised of 65 pieces, 3 land snail shells and 62 cattle bones belonging to calves and adult animals (Table 4). Calves are represented by 2 skulls, 4 occipital fragments, 1 horn, 2 jaw fragments, 1 atlas, 1 sacrum, 1 complete pelvis, 2 right scapulas, 1 rib fragment, 1 right humerus, 2 femurs (right and left), 1 proximal femur, 1 radio-ulna, 1 left tibia, 1 metacarpal, 1 metatarsal, and 1 calcaneum. Adult cattle are represented by 3 mandibles (2 right and 1 left), 1 jaw fragment, 5 lumbar vertebras, 1 pelvis, 1 right femur, 2 distal humeri (left and right), 1 right radio-ulna, 2 tibiae (1 complete right and 1 distal left), 2 right metacarpal, 1 metatarsal, 2 astragal, and 2 tarsals. The bone sample seems to include the remains of at least four animals, two calves and two adult individuals. The absence of any anatomic connection between the recorded pieces, and the breakage of some marrow-rich long bones suggest the animals were butchered at the site. Amachita VII, the remaining site from the camp cluster was settled by seven families from Mahanna, a village located some 20 km northeast of the Yaere, the hinterland depression. The bone sample is small in size, amounting to 19 pieces and consists of two land snail shells, two sheep/goat and 15 cattle bones (Table 4). Sheep/goat is represented by 2 lumbar vertebras of a mature animal. The collected cattle bones are those of an adult individual. They are comprised of 1 left mandible, 1 sacrum fragment, 2 scapula proximal ends, 8 radio-ulna fragments, 1 right distal radius, 1 right proximal ulna, and 1 proximal tibia. The sample seems to have resulted from the consumption of small shares of meat that may have been brought from the main village. T he Age d ips e c a mp clu st e r Four faunal samples were collected from the Agedipse camp cluster. They range in size from a minimum of 10 pieces (Agedipse IV) to a maximum of 69 (Agedipse II). The frequency of land snails, with a single specimen found at Agedipse IV, is negligible when compared to the Amachita cluster (Table 4). Cattle bones are predominant in all cases, with the frequency varying from 7 (Agedipse IV) to 60 (Agedipse II). The proportion of sheep/goat bones is surprisingly low and varies from 2 recorded at Agedipse IV to 13 found at Agedipse III. 54 Agedipse I was settled by eight household units from the village of Kulkule. The collected faunal remains amount to 23 pieces divided into 19 cattle and 4 sheep/ goat bones (Table 4). The sheep/goat bones belong to an adult individual. They are represented by 1 mandibular fragment, 1 right radio-ulna, 1 right scapula, and 1 left humerus. The cattle bones recorded belong to three separate individuals, a calf, a young animal, and an adult. The calf is represented by 2 mandibles (left and right), 1 complete right humerus, and 1 mesial humerus. The young animal is represented by 1 cranium, 1 mandibular fragment, 1 atlas fragment, 2 scapulas (right and left), 2 humeri (left and right), 1 right femur, 1 right tibia, 2 radio/ulna (left and right), and 1 left metatarsal. The adult individual is represented by 2 left calcaneum fragments and 1 second phalanx. The axial skeleton is poorly represented with only five elements recovered. The skewed distribution of anatomical parts, with limbs bones largely predominant, may have resulted from the transfer of meat shares brought from outside to the site. Alternatively, it can be suggested that calves or very young animals in a poor health during the peak of the dry season may have been butchered and shared with the inhabitants of nearby settlements. Agedipse II was settled by five family groups originating from Magourde, a mixed farming community. The faunal material collected amounts to 69 pieces and consists of 60 cattle and 9 sheep/goat bones (Table 4). Sheep/goat are represented by 2 skulls, 2 horns, 2 mandibles (left and right), 2 vertebras, and 1 astragal, all from adult animals. The cattle bones belong to at least four individuals, one calf and three adults. The calf is represented by 1 skull, 1 horn, 1 proximal tibia, 1 metacarpal, and 1 metatarsal. Adult animals are represented by 3 skulls, 2 mandibles, 5 mandibular fragments, 17 vertebras, 1 sacrum, 1 complete and 4 scapula fragments, 5 pelvis fragments, 5 rib fragments, 2 humerus (left and right), 2 femurs (left and right), 1 right radioulna, 5 metacarpals, 4 metatarsals, and 3 phalanxes. An interpretation of the Agedipse II faunal sample is particularly delicate. It is the smallest camp of the whole cluster with the largest sample of animal bones. All the collected bones were found without anatomic connection; a feature that generally indicates scattered dead animal carcasses. The material at hand thus seems to have resulted from deliberate food consumption and refuse disposal. Agedipse III, the largest camp of the cluster was settled by sixteen households from the village of Hinduk. The faunal sample is comprised of 56 animal bones, 13 from sheep/goat and 43 from cattle (Table 4). The sheep/goat bones belong to two adult animals, as suggested by the two recorded skulls, one of a ewe and the other of a male goat. The remaining pieces include, 2 jaw fragments, 1 left pelvic fragment, 2 metacarpals (right and left), and Augustin F.C. Holl 6 phalanxes. The recorded cattle bones are those of at least three individuals, one young and two adults. The young animal is represented by 1 scapula and 1 complete metacarpal. The adult bones consist of 2 scapulas, one complete and the other fragmented, 4 femurs (2 left and right), 4 humeri (2 left and 2 right), 4 tibiae (2 left and 2 right), 4 radio-ulnas (2 right and 2 left), 2 metacarpals, 5 astragals, 5 calcanei, 5 tarsals, and 6 carpals. There is an interesting difference between the patterning of sheep/goat and that of cattle bones. Elements from the axial skeleton are absent from the sample of the latter and more or less well represented in the assemblage of the former. The ewe and the male goat appear to have been butchered in the dry season camp and probably shared. Cattle meat appears to have been brought to the camps as limbs pieces, as if especially processed to be carried away. Agedipse IV, the remaining camp of the cluster, was settled by five family groups originating from Tumam. The sample of faunal material is the smallest of all the documented cases with only 10 pieces, 1 land snail shell, 2 sheep/goat and 7 cattle bones (Table 4). All the collected bones are part of the axial skeleton, 2 jaw fragments from the sheep/goat represented, and 1 skull, 1 skull fragment, 1 jaw fragment, and 3 vertebral fragments from the calf. The interpretation of the faunal assemblage is particularly difficult. No gnaw marks were observed on the studied bones, but the selective representation of head bones suggests the activity of scavengers after the abandonment of the camp. The faunal remains from the dry-season camps result from two distinct processes, human consumption of livestock meat and the dispersal of skeletal elements after the natural death of the animals. Meat consumption appears to have operated along two overlapping tactics; in one, the consumed meat came from animals butchered at the site. In the other, shares of meat, either sun dried, smoked, or not, were brought from the main village to the dry-season camps. Pat t e r n s of i nt e n si f icat ion The concept of intensification is used here in a strictly relational perspective. It aims to single out any significant difference in output well beyond local subsistence needs. Production intensification seems to be driven by the combination of a few independent variables: 1) the constant pressure exerted on all adult males aged eighteen years and above to raise cash to pay for the annual per capita tax; 2) the proximity of large markets from the nearby towns of Kusseri in Cameroon and N’Djamena in Chad Republic; and 3) for the younger segment of the population, the appeal of and desire to access certain sides of mass-consumption. Shuwa-Arab economics: livestock management and animal consumption 55 Fig. 10: View of a goat-milking station from Djidat I. There are few indications of production intensification in two components of the production-subsistence continuum. One involves poultry and the other goats. The first one is documented in the settlements layout by the presence of sets of chicken coops. They are found in a number of permanent and semi-permanent settlements. In permanent villages, the frequency of chicken coops is confined within a narrow range of 5-9. In fact, localities such as Abuzrega and Djidat II that are devoid of milking installations have the highest number of chicken coops, 8 and 9 respectively. In the semi-permanent settlements, chicken coops are recorded in four villages out of seven with frequency varying from 1 to 27. Two of the villages, Bilbede and Ngada IV, with 22 and 27 chicken coops, respectively, stand out as poultry production centers. The second component of the production-subsistence continuum subject to intensification revolves around the production of goat milk. It is indicated in site layout by the presence of milking stations. Dairy products are an essential component of the herders’ diets and each family owning livestock, cattle, or sheep/goat, or both, collect a certain amount of milk for household consumption during the adequate period of the year. This household milking is carried out without special installations. The documented milking-stations, exclusively for goats, are special purpose features consisting of a series of equidistant wooden poles set in pens, round huts, courtyards, and even along walls (Fig. 10). They are used to streamline the milking process. As far as the social division of labor is concerned, milking operations, transportation, as well as market transactions are all carried out by females. Milking-stations have been recorded at two permanent villages, Djidat I and Marafin, occurring 10 and 5 times, respectively. The former village is clearly specialized in animal products, with seven chicken coops and ten milking-stations for eleven households. The latter has five milking-stations and five chicken coops for ten households. Cr af t s a nd special i zed occupat ion s A small array of crafts and occupational specializations are represented in the material record from the tested settlements. For example, the Imam (Marabout), the Moslem scholar in charge of the Friday Mosque and the “boarding” Koranic school of Djidat II as well as the operator of the engine-pulled mill also located at Djidat II. He is not a resident of that settlement and has to commute from Houlouf every day. Blacksmiths installations or products have been found at two settlements, at Djidat II and Amachita V. The former consists of a blacksmith workshop equipped with a furnace, bellows, blow-pipes, as well as a supply of scrap metal. In the latter, two freshly made pieces of equipment, an iron axe and a socketed adze, were lost in the dry season camp. A shoe-polisher’s box was found in house 35 at Ngada IV suggesting that the house owner may have 56 Augustin F.C. Holl been involved in a part-time work in the nearby towns, Kusseri in Cameroon or Ndjamena, the capital of the Chad Republic, on the opposite river bank. And finally, a reed-mat weaving workshop was recorded in house 26 at Ngada IV. There is a high demand for such mats in villages and cities during the dry seasons, when they are used to build open shelters in courtyards. Conclu sion Subsistence activities and a certain but narrow range of more specialized crafts are carried out in many of the settlements investigated in this project. In terms of diversity, intensity, and frequency according to settlement categories, permanent villages easily rank first, followed by semi-permanent villages, and finally, dry season camps. With a single exception represented by iron artifacts lost by a blacksmith at Amachita VI, livestock husbandry is the key activity performed in all dry season camps. The analysis of animal bones brings to light interesting results. Sophisticated quantitative analyses of faunal remains can be applied to a very narrow range of settlements, namely short term single occupation sites as is the case for the tested dry season camps that were settled between March and May/June 1990. In this case only, it is possible to address issues concerning the number of animals represented in the sample (MNI), the body parts brought to the site, as well as patterns of meat consumption, with an accurate control of the evidence. In all other cases, from the semi-permanent as well as permanent villages, the palimpsestic nature of the faunal assemblages precludes any reasonable assessment of such variables as the number of butchered animals. At best, the proportional analysis of different parameters from faunal remains based on the crudest yardstick, the number of rests (NR) can be performed. Finally, the distributional pattern of species in each of the investigated faunal assemblages alone is not discriminating enough to allow for a subtle differentiation between distinct degrees of reliance on livestock products. Ack nowle dge me nt s The research reported in these pages was funded by National Geographic Society Grant # 6378-98 and 3715-87. I wish to thank Mahamat Bahr Maaruf, Sultan of Logone-Birni for his understanding, kindness and support in the field. I am grateful to the people of Houlouf for their hospitality and to the Shuwa-Arabs from the sampled sites to have allowed this research to take place. Bibl iog r aphy Agorsah E.K., 1985.
