Dietary patterns at two Bronze Age sites in the Hexi Corridor are investigated by the analysis of stable carbon and nitrogen isotopes in faunal bone collagen. The findings are compared with archaeobotanical remains from one of the sites which include high proportions of millet (Panicum miliaceum and Setaria italica) as well as the western derived cereals wheat (Triticum aestivum), barley (Hordeum vulgare) and oat (Avena sativa). The isotopic data indicate domestic omnivores (Canis and Sus) had diets dominated by millet. Minimally offset δ15N values between herbivore and omnivore fauna suggest low consumption of animal protein by omnivores. Diets of herded animal (Bos and Caprinae) included only low proportions of C4 foods, suggesting that these animals were not regularly foddered with millet plants, and that their grazing areas were mostly beyond the agricultural zone. The wide range in δ15N values amongst herbivore fauna (4.1‰–11.8‰) suggests grazing occurred in a variety of ecological zones, and this would be consistent with the occurrence of long-distance transport of livestock in the region.  相似文献

The Longwangchan Paleolithic site, situated on the Yellow River terraces in the Hukou area, Shaanxi province, China, was found in 2003–2004, and two areas (Localities 1 and 2) of the site were excavated in 2005–2008. Abundant stone artifacts including microliths, a grinding stone fragment and a shovel, with some animal bones and shells, were recovered from Locality 1. In this study, the cultural deposits from Locality 1 were dated using radiocarbon and optical dating techniques, and the sediment properties of the deposits were analyzed. The results show that the age of the deposits ranges from 29 to 21 ka and most of them were deposited between 25 ka and 29 ka. This indicates that corresponds to late Marine Isotope Stage (MIS) 3 and early MIS 2. During the human occupation period, the climate in this area became colder and drier. Sediments from beds where the grinding slab and the shovel were found were dated to ∼25 ka, which is the oldest among the grinding stones found in China. The microliths and the grinding stone are important evidence for an incipient socio-economic process that eventually led to the regional transition from hunting-foraging to farming.  相似文献

The aim of this work is to study, from a bioarchaeological perspective, the diet and oral health of the populations that inhabited Central Argentina in two periods which would reflect changes in subsistence strategies: earlier late Holocene (ca. 2500–1500 years BP) and later late Holocene (ca.1500–400 years BP). The sample is composed by 83 adult individuals from 47 archaeological sites. We considered five non‐specific indicators of stress, infectious and degenerative diseases: hypoplasia of dental enamel, dental caries, abscesses, antemortem teeth loss, and calculus. We also considered hypercementosis, dens in dens, and agenesis. We test intraobserver error by means of intraclass correlation coefficient and analysis of variance of repeated measures. We calculated prevalence by sex, age, geographic subregion, and chronological period. We applied Chi‐square (X2) to test statistical significance of observed differences. Considering the sample as a whole, low prevalence of dental caries (10.27%), abscesses (16.52%), and hypoplasia (10.84%) are coincident with values observed for populations with mixed or hunter‐gathering subsistence strategy. In later late Holocene, high incidence of caries should be considered as indicator of consumption of C4 vegetables or other carbohydrate‐rich vegetables, such as legumes of Prosopis sp. Also, moderate values of dental enamel hypoplasia should be related with metabolic‐systemic stress episodes. Summarizing, these results are coincident with isotopic, archaeological, and ethnohistorical evidences which suggest climatic, social, and demographic pressures that might have affected the lifestyle of these populations before the Spanish conquest.

Abstract: Tracing the commodity chain of broccoli from Nashville, Tennessee supermarkets to Maya farmers in highland Guatemala, this paper examines relations of desire and political economic power. We argue that the global broccoli trade is shot through with desires—desires of Western consumers to eat healthy foods as well as desires for Maya farmers to get ahead economically. Such desires simultaneously subvert and sustain the hegemonic constellations that anchor crucial nodes in the international broccoli trade.  相似文献

After two turbulent years in which different pathways for the future of the political and institutional framework of Portugal clashed, the country began a process of consolidation of the democratic institutions delineated between 1975/6. However, the role played by the military in the fall of the previous dictatorial regime and the fragility of the new democratic institutions did not allow their immediate withdrawal from political life. The President of the Republic was a military man and the political parties had agreed to maintain an unelected sovereign body, the Council of the Revolution, which only dissolved in 1982. Based on primary sources that only recently became available, this article presents some elements that help to understand the success of democratic consolidation in Portugal. This long process should not be interpreted as a confrontation between civilians, desirous to put an end to military tutelage, and the military, who at all costs sought to keep their privileges. The dividing line should be placed between those who defended the maintenance of the status quo, and the supporters of military subordination to the civil power.  相似文献

Domestic commercial land acquisition is a recent phenomenon in Nepal; it is rapidly expanding and increasingly occupying productive agricultural land for real estate and other non-agricultural commercial purposes. This paper analyses the present situation and the implications of domestic land acquisition, and identifies actors and forms of land deals and associated conflicts. The study was conducted in Kathmandu Valley (27° 32′ 13″ N to 27° 49′ 10″ N and 85° 11′ 31″ E to 85° 31′ 38″ E) and Chitwan District (83°54′ 45″ to 84°48′15″ E and 27°21′45″ to 27°52′ 30″ N), the areas of Nepal most affected by domestic land acquisition. In the absence of statistical material, purposive sampling was used to identify households for a survey of 208 respondents; this was complemented by qualitative research and a review of media and other documents. Respondents confirmed that land acquisition is increasing at a very rapid rate and is driven by a nexus of politicians, land brokers and real-estate actors, and that it has caused not only food insecurity but also numerous conflicts between local people and the land deal actors. Existing policies and legislations were found to be inadequate to address the challenges brought about by the domestic land acquisition process in Nepal.  相似文献

This paper examines Fannie Lou Hamer's Freedom Farms, a 1969 farming cooperative in Sunflower County, Mississippi. Specifically, this paper interrogates how Hamer's identity as a Black southern woman influences her formulation and daily activities at Freedom Farms. Theoretically, this paper situates Hamer as an expert agrarian labourer and knowledge producer who exists within a history of Black women who have always been utilised for their agrarian knowledge, but given little credit. Hamer's knowledge is a part of her body. This paper argues that Freedom Farms is a Black radical geography operating at three scales: the body, the farm and the southern agrarian landscape. This paper utilises Hamer's speeches, interviews and other archival documents to understand Hamer's efforts. Hamer's agrarian landscape is wrought with pain, but also the insistence in the economic opportunity that exists for Black people in agrarian spaces.  相似文献

Abstract

Two Scythian-Sarmatian period pits dated to the 5th–1st centuries b.c. were discovered while excavating the Chalcolithic site of Zanovskoe, located on a floodplain of the Donets River in the steppe region of eastern Ukraine, Lugansk oblast. No contemporaneous settlement sites are known in the region. Archaeobotanical analysis was conducted on charred plant macrofossils recovered from pits at the site. The crop assemblage consisted of hulled barley and broomcorn millet, from which AMS radiocarbon dates were obtained. Other identified plant species mostly constituted arable weeds and wetland plants. The archaeobotanical assemblage implies floodplain cereal cultivation strategies among the steppe inhabitants during this period.  相似文献

Books discussed here focus upon the initial peopling of the Americas and the worldwide development of food production. They examine postulated historical instances in which genes, languages, and cultural elements appear to correlate, indicating major population movements in prehistory. Recognized experts in historical linguistics, archaeology, and molecular genetics review current methodology, available data, and models of global and regional population history. A more holistic approach and a greater understanding of human population dynamics are called for to improve our reconstruction of these past events.  相似文献

This research aims to shed light on the early stages of agricultural development in Northern Africa through the analysis of the rich macro-botanical assemblages obtained from Ifri Oudadane, an Epipalaeolithic–Early Neolithic site from North-East Morocco. Results indicate the presence of domesticated plants, cereals (Hordeum vulgare, Triticum monococcum/dicoccum, Triticum durum and Triticum aestivum/durum) and pulses (Lens culinaris and Pisum sativum) in the Early Neolithic. One lentil has been dated to 7611 ± 37 cal BP representing the oldest direct date of a domesticated plant seed in Morocco and, by extension, in North Africa. Similarities in both radiocarbon dates and crop assemblages from Early Neolithic sites in Northern Morocco and the Iberian Peninsula suggest a simultaneous East to West maritime spread of agriculture along the shores of the Western Mediterranean. Wild plants were abundantly collected in both the Epipalaeolithic and the Early Neolithic periods pointing to the important role of these resources during the two periods. In addition to fruits and seeds that could have been consumed by both humans and domesticated animals, fragments of esparto grass (Stipa tenacissima) rhizomes have been identified. This is a western Mediterranean native plant that may have been used as a source of fibres for basketry.  相似文献
