This paper presents the initial results of excavations at Kanjera South, located on the Homa Peninsula in Western Kenya. Since 1995, our exploration of this locality has yielded a combination of artefacts and well preserved faunal remains in a sedimentary context that also allows for environmental reconstruction. Here we examine the history of exploration of Kanjera and its significance in the development of palaeoanthropological research in East Africa. We also summarise our findings from the recently discovered Oldowan site. Taphonomic analyses suggest that the archaeological layers were formed at least partially by hominin activity. Artefacts made from a wide variety of raw materials are abundant, as are animal bones. Results of our first analyses confirm that Oldowan hominins had considerable behavioural flexibility and occupied a range of habitats.Cet article présente des résultats préliminaires de nos fouilles au site de Kanjera South, situé sur la péninsule de Homa au Kenya occidental. Depuis 1995 nos explorations à cette localité ont produit une combinaison des outils lithiques et des restes fossils dans un bon état de conservation venant d’un contexte sédimentaire qui permet également les reconstitutions paleoenvironnementaux. Ici nous examinons l’histoire de l’exploration de Kanjera et de son importance dans le développement de la recherche paleoanthropologique en Afrique de l’Est. Nous récapitulons également nos résultats du gisement récemment découvert d’Oldowan. L’étude taphonomique suggère que les couches archéologiques ont été formées au moins partiellement par l’activité des hominins. Les objets fabriqués faits à partir d’une grande variété de matières lithiques sont abondants, de même que les os animaux. Les résultats de nos premières analyses confirment que les hominins d’Oldowan ont eu une flexibilité de comportement considérable et ont occupé une gamme d’habitats différents. 相似文献

Nadung’a 4 is one of the single carcass pachyderm sites recorded in East Africa during the Lower and Early Middle Pleistocene. The site has yielded an abundant lithic assemblage in close association with the partial carcass of an elephant. Conjoined pedological, geoarchaeological, spatial, technological, and taphonomical analyses have been carried out to address the relationship between hominids and elephant. The resulting data are consistent with a non-fortuitous association between both categories of remains. The lithic artefacts do not match a classical Acheulean tool-kit, as would be expected for the time period ascribed to the site, and the functional patterns inferred from their analysis make this site radically different from other purported butchery sites. The implications of these original features are discussed. 相似文献

Near Eastern fieldwork in mining archaeology and archaeometallurgy began at Timna (Israel) in the 1960s and 1970s and continued in Feinan (Jordan) in the 1980s and 1990s. For the first time, Bronze Age copper mines were excavated and cleared and importance was given to the slag recovered. At both sites copper was produced for over 5000 years, from the Chalcolithic to the Mamluk periods. Although the broad outlines of technical development can be traced, much remains to be learned in future studies. 相似文献

An American specialist on Russia's agrarian sector and two collaborators explore the effects of distance to nearby urban markets on the agricultural output and income of Russian rural households. Unlike previous studies that have largely tested such effects on the basis of household distance from relatively large oblast administrative centers, the authors adopt a micro-level scale of analysis, focusing on distance from smaller rayon centers. Comparison of two sample populations (near vs. remote from rayon center) from a larger survey population of 900 households in nine representative regions of Russia reveals marked differences in household incomes, commodity output, and real holdings of land that are statistically verified by a linear regression model.

秦、西汉时期关中农业发展的地域差异 总被引:2,自引:0,他引:2
在秦汉定都关中期间,围绕都城的建设与发展,关中内部的农业生产格局发生了较大变化,生产重心日益向东北方向倾斜。西汉后期关中东部渭北地区是关中农业生产的重心;西南部的农耕经济则几乎完全遭到毁灭;西北、东南部的农业生产虽有较大发展,其速度较东北部而言,却相对缓慢。 相似文献

"两个飞跃"是邓小平为中国社会主义农业改革和发展设计的伟大纲领。从对"第一个飞跃"的肯定和支持,到对"第二个飞跃"的探索和展望,邓小平始终坚持历史发展的辩证法,不仅科学地规划了"两个飞跃"渐次实现的现实道路,而且为我们积极发展现代农业、扎实推进社会主义新农村建设提供了重要的方法论依据,具有重大而深远的现实意义。 相似文献

Differences in dental health of prehistoric human groups are commonly attributed to specific subsistence practices, whereby food foragers generally have a lower incidence of dental disease than agriculturalists. Dental health was assessed on a sample of 135 human skeletons from northwest Mexico that date to the Early Agricultural period (1600 BC–AD 200), which coincides with the initial introduction of domesticated cultigens into the region c. 2000 BC. High rates of dental caries (13.5%) and antemortem tooth loss (17.6%) encountered in these prehistoric forager‐farmers from the Sonoran Desert were determined to be the result of the consumption of highly cariogenic local wild resources such as cactus. These patterns mask the degree of reliance on agriculture in the area and highlight the importance of constructing local nutritional histories to better understand the diversity of human diets and their relationships to health and disease.

Cet article présente les caractéristiques et l'évolution de la propriété foncière, du marché foncier et des systèmes de production agricoles en Lombardie orientale au 19e siècle. L'auteur analyse les impacts sur l'exploitation de la terre de la substitution des propriétaires fonciers nobles par des bourgeois; des maladies du ver à soie et des vignobles, de l'arrivée des grains américains moins chers; de l'utilisation d'engrais chimiques et d'équipements modernes. Il montre que si la petite propriété représente toujours près d'un tiers du total et que la magnanerie et la viticulture diminuent, il est relevé une croissance des cultures céréalières et fourragères et des dépenses consacrées aux innovations technologiques. Il signale la rationalisation des cultures, l'amélioration des rendements et de la qualité des récoltes ainsi que des revenus non déclarés pour éviter les impôts et explique pourquoi les investisseurs préfèrent les petits aratori comportant des mûriers et des vignobles. Enfin, il donne à voir que l'organisation des exploitations reste liée au degré de risque pris par le propriétaire (la rente fixe garantie par le bail à ferme payé en argent ou une gestion directe de la propriété) et aux cultures (la présence des vignobles et de la magnanerie favorisant les sharecropping contracts). 相似文献

This paper is a presentation of a comparison between prehistoric food culture signals obtained through analyses of lipid food residues in pottery, i.e. pottery-use, from settlement remains on one hand and bone chemical analyses of human skeletal remains from an adjacent and contemporary cemetery on the other. The materials derive from the Early Medieval site Tuna in Alsike par., Uppland, Sweden. The results show a discrepancy between the two food signals and it is argued that pottery-use do not by necessity reflect everyday diet. But it is also argued that the integration of several food signals together with contextual archaeological data is a fruitful way to begin to understand the complexity of prehistoric cultures of food. 相似文献

During the Middle Ages, the economies of Europe, the religious directives involving dietary requirements, and the general human subsistence base were transformed. These complicated and intertwined issues are starkly revealed in an isotopic study of two inland Italian human populations that are separated by approximately 850 years in time. Stable carbon (δ13C) and nitrogen (δ15N) isotopic values observed in human dentin and bone collagen from the sites of early medieval Castro dei Volsci and late medieval Rome are consistent with diets that differed substantially. As the North Atlantic opened to fishing and food preservations methods improved, Mediterranean peoples increased their fish consumption dramatically, and in doing so, met the religious directives of the Catholic Church. By analyzing both teeth and bone collagen within individuals, long-term feeding behaviors are documented, and the utility of last erupted teeth collagen as sources of adult dietary information is established. This study offers the first physical evidence of this new economic reality linking the Atlantic and Mediterranean economies at the end of the Middle Ages. 相似文献
