Subsistence Strategies (subsistence + strategy)
Selected AbstractsThe Shaping of San Livelihood Strategies: Government Policy and Popular ValuesDEVELOPMENT AND CHANGE, Issue 3 2002Michael Taylor The importance of understanding the livelihood strategies of poor people has received a fresh impetus over the last few years with the emphasis by many Western donors on poverty reduction. This article examines the livelihood strategies of San people in three villages on the northern peripheries of the Okavango Delta in Botswana. Their economic marginalization is compounded by their ethnic background; a stigma that also marginalizes them politically and socially. The analysis presented here not only challenges stereotypes commonly associated with San by demonstrating the interconnectedness of different means of ,looking for life', but it also brings to the fore the importance of considering institutional factors that regulate livelihood strategies. The article focuses on some of the unexpected consequences of the wider policy environment, and on how the values associated with different ways of life affect material subsistence strategies. These are particularly pronounced for people with a heritage of hunting and gathering living in a society that regards such practices as ,backward'. [source] THE A.D. 1300 EVENT IN THE PACIFIC BASIN,GEOGRAPHICAL REVIEW, Issue 1 2007Patrick D. Nunn ABSTRACT. Around a.d. 1300 the entire Pacific Basin (continental Pacific Rim and oceanic Pacific Islands) was affected by comparatively rapid cooling and sea-level fall, and possibly increased storminess, that caused massive and enduring changes to Pacific environments and societies. For most Pacific societies, adapted to the warmer, drier, and more stable climates of the preceding Medieval Climate Anomaly (a.d. 750,1250), the effects of this A.D. 1300 Event were profoundly disruptive, largely because of the reduction in food resources available in coastal zones attributable to the 70,80-centimeter sea-level fall. This disruption was manifested by the outbreak of persistent conflict, shifts in settlements from coasts to refugia inland or on unoccupied offshore islands, changes in subsistence strategies, and an abrupt end to long-distance cross-ocean interaction during the ensuing Little Ice Age (a.d. 1350,1800). The A.D. 1300 Event provides a good example of the disruptive potential for human societies of abrupt, short-lived climate changes. [source] Lifestyle, occupation, and whole bone morphology of the pre-Hispanic Maya coastal population from Xcambó, Yucatan, MexicoINTERNATIONAL JOURNAL OF OSTEOARCHAEOLOGY, Issue 3 2007Isabel S. Wanner Abstract The present bioarchaeological study examines the external diaphyseal geometric properties of humeri, radii, femora and tibiae of the Classic period skeletal population of Xcambó, Yucatan, Mexico. The diaphysial proportions are evaluated using a biomechanical approach together with data from the material context and other osteological information. Our intent is to provide new answers to questions concerning lifestyle, domestic labour division and subsistence strategies of this coastal Maya settlement that was inhabited from the Late and Terminal Preclassic (300 BC,350 AD) to the Postclassic Period (900,1500 AD). Our results provide evidence for a marked sexual division of labour when compared with values from contemporaneous inland populations. The overall male and female loading patterns differ remarkably in terms of form and in bilateral comparison. A high directional asymmetry in the upper limbs is evident among males, a condition related to maritime transportation and trading activities. On the other hand, female upper limbs are characterized by very low side differences. Forces on the arms of women were probably dominated by food processing, in particular the grinding of grains or seeds. In the lower limbs, males show significantly higher anteroposterior bending strengths, which can be explained by greater engagement in transportation tasks and carrying heavy loads. In the course of the Classic period (350,900 AD), diachronic changes affect the male sample only, which suggests a shift of occupational pattern and physical demands. This shift, in turn, reflects Xcambó's changing role as the centre of a densifying settlement area and its place in the trading activities of northern Yucatan. Other topics of discussion relate to general regional trends and local prehispanic subsistence strategies. Our conclusions emphasize the value of geometric long bone analysis in the reconstruction of activity patterns and lifestyles in ancient coastal settlements. Copyright © 2007 John Wiley & Sons, Ltd. [source] Carbon and nitrogen stable isotopes as tracers of change in diet breadth during Middle and Upper Palaeolithic in EuropeINTERNATIONAL JOURNAL OF OSTEOARCHAEOLOGY, Issue 3-4 2004D. Drucker Abstract Carbon and nitrogen stable isotope ratios in fossil bone collagen have been used as evidence for an increase of diet breadth between Middle Palaeolithic Neanderthals and Early Upper Palaeolithic anatomically modern humans. In this paper, we revisit the rules of palaeodietary reconstruction using collagen stable isotopes and reassess the possible isotopic signatures of potential protein resources available to prehistoric humans. It appears that the interpretation of the human's isotopic signature does not necessarily imply a significant proportion of aquatic-derived protein in the diet neither for Neandertal nor for first anatomically modern humans in Europe. Exploitation of aquatic ecosystems by humans needs to be supported by further zooarchaeological evidence. Nevertheless, isotopic biogeochemistry of fossil human collagen can be very useful in palaeodietary reconstructions provided that basic rules are followed while selecting samples of coeval fauna, in order to establish the end members of different food resources. Significant progress investigating the evolution of subsistence strategies in fossil hominids is expected from a combination of zooarchaeological and isotopic data.

Tyler Path analysis was used to investigate the impact of childhood sexual abuse on later sexual victimization among 372 homeless and runaway youth in Seattle. Young people were interviewed directly on the streets and in shelters by outreach workers in youth service agencies. High rates of both childhood sexual abuse and street sexual victimization were reported, with females experiencing much greater rates compared with their male counterparts. Early sexual abuse in the home increased the likelihood of later sexual victimization on the streets indirectly by increasing the amount of time at risk, deviant peer affiliations, participating in deviant subsistence strategies, and engaging in survival sex. These findings suggest that exposure to dysfunctional and disorganized homes place youth on trajectories for early independence. Subsequently, street life and participation in high-risk behaviors increases their probability of sexual victimization. [source] The Place of "Others" in Hunter-Gatherer IntensificationAMERICAN ANTHROPOLOGIST, Issue 2 2005DONALD H. HOLLY JR. Archaeologists are interested in understanding the conditions under which hunter-gatherer intensification occurs. Typically, most models assign primacy to population pressure or social relations and address intensification as it occurs among foragers inhabiting arid or temperate environments. In this article, I explore episodes of resource intensification and "deintensification" on the subarctic island of Newfoundland. Correlating periods of resource intensification and "deintensification" with changes in the social landscape, I argue that the presence or absence of "Others" played a significant role in informing hunter-gatherer subsistence strategies and settlement patterns. [source] CONTRASTING SUBSISTENCE STRATEGIES IN THE EARLY IRON AGE?OXFORD JOURNAL OF ARCHAEOLOGY, Issue 2 2009AND THE THRACIAN PLAIN, BULGARIA, HUNGARY, NEW RESULTS FROM THE ALFÖLD PLAIN Summary. What can students of the past do to establish the predominant land-use and settlement practices of populations who leave little or no artefactual discard as a testament to their lifeways? The traditional answer, especially in Eastern Europe, is to invoke often exogenous nomadic pastoralists whose dwelling in perpetuo mobile was based on yurts, minimal local ceramic production and high curation levels of wooden and metal containers. Such a lacuna of understanding settlement structure and environmental impacts typifies Early Iron Age (henceforth ,EIA') settlements in both Bulgaria and eastern Hungary , a period when the inception of the use of iron in Central and South-East Europe has a profound effect on the flourishing regional bronze industries of the Late Bronze Age (henceforth ,LBA'). The methodological proposal in this paper is the high value of palynological research for subsistence strategies and human impacts in any area with a poor settlement record. This proposal is illustrated by two new lowland pollen diagrams , Ezero, south-east Bulgaria, and Sarló-hát, north-east Hungary , which provide new insights into this research question. In the Thracian valley, there is a disjunction between an area of high arable potential, the small size and short-lived nature of most LBA and EIA settlements and the strong human impact from the LBA and EIA periods in the Ezero diagram. In the Hungarian Plain, the pollen record suggests that, during the LBA,EIA, extensive grazing meadows were established in the alluvial plain, with the inception of woodland clearance on a massive scale from c.800 cal BC, that contradicts the apparent decline in human population in this area. An attempted explanation of these results comprises the exploration of three general positions , the indigenist thesis, the exogenous thesis and the interactionist thesis. Neither of these results fits well with the traditional view of EIA populations as incoming steppe nomadic pastoralists. Instead, this study seeks to explore the tensions between local productivity and the wider exchange networks in which they are entangled. [source] Patterns of systemic stress during the agricultural transition in prehistoric JapanAMERICAN JOURNAL OF PHYSICAL ANTHROPOLOGY, Issue 1 2010Daniel H. Temple Abstract This study documents and interprets systemic stress during the agricultural transition in prehistoric Japan using linear enamel hypoplasia (LEH) defects and cribra orbitalia (CO) lesions. Middle to Final Jomon cultures (5000,2300 BP) from Honshu Island represent the foraging samples, while Yayoi cultures (2500,1700 BP) represent the early agricultural samples. Jomon foragers from eastern Japan had broad-based, intensive economies. Jomon foragers from western Japan had a greater focus on seasonally available, nutritionally poor resources, while Yayoi people were descendents of migrants from the East Asian continent and introduced wet rice economies to Japan. This study tests the hypotheses that wet rice economies will be associated with a lower prevalence of teeth/individuals affected by LEH defects in western Japan, while few differences in the prevalence of teeth/individuals with LEH defects will be observed between eastern Jomon people and Yayoi farmers. It is further predicted that similar CO prevalence will be observed between Jomon and Yayoi people given environmental similarities. Significantly greater frequencies of teeth affected by LEH defects are observed among western Jomon compared to Yayoi people. The prevalence of teeth with LEH defects is slightly elevated among eastern Jomon foragers compared to Yayoi agriculturalists. Significant differences in CO prevalence are not observed. Systemic stress prevalence in western Japan likely declined following wet-rice agriculture because this crop provided a predictable, renewable resource base. Systemic stress prevalence was similar between eastern Jomon and Yayoi people because both groups practiced intensive subsistence strategies. Similar CO prevalence reflects infectious diseases associated with living conditions. Am J Phys Anthropol, 2010. © 2009 Wiley-Liss, Inc. [source] MOSAICS OF MAYA LIVELIHOODS: READJUSTING TO GLOBAL AND LOCAL FOOD CRISESANNALS OF ANTHROPOLOGICAL PRACTICE, Issue 1 2009Rebecca K. Zarger The particularities of how residents in Southern Belize encounter the vagaries of what is commonly referred to as a "global food crisis" (between 2006 and 2008) are explored in this paper. Belize, like many other nation states around the globe, has been structurally (and sequentially) "readjusted" by transnational lending institutions over the last several decades. Cyclical shifts in agricultural practices have taken place in many Maya communities in Southern Belize in the last decade, partly in response to migration, a severe hurricane, land tenure conflicts, and within the last year, skyrocketing staple prices and food scarcity. The costs of basic staples such as corn, wheat, and rice have nearly doubled, in parallel with much of the rest of the globe during the same time frame. Shifts in subsistence strategies have significant implications for the power and politics of land use, access, and mobility. Furthermore, they reflect centuries-old ways of adjusting to changing circumstances in global markets and colonial and postcolonial realities. I conclude by emphasizing the importance of incorporating political and historical ecologies of land use and food production when considering the local impacts of global food crises. [source] Why we're still arguing about the Pleistocene occupation of the AmericasEVOLUTIONARY ANTHROPOLOGY, Issue 2 2007Nicole M. Waguespack Abstract Although empirical issues surround the when, how, and who questions of New World colonization, much of current debate hinges on theoretical problems because it has become clear that our understanding of New World colonization is not resolute.1 In fact, the central issues of debate have remained essentially unchanged for the last eighty years. The now classic and probably incorrect story of New World colonization begins in Late Pleistocene Siberia, with small a population of foragers migrating across Beringia (,13,500 calendar years before present (CYBP) (Box 1) through an ice-free corridor and traveling through the interior of North America. High mobility and rapid population growth spurred southward expansion into increasingly distant unoccupied regions, culminating in the settlement of the Southern Cone of South America. Armed with the skills and weapons needed to maintain a megafauna-based subsistence strategy, early colonists necessarily had the adaptive flexibility to colonize a diverse array of Pleistocene landscapes. For a time, this scenario seemed well substantiated. The earliest sites in South America were younger than their northern counterparts, fluted artifacts were found across the Americas within a brief temporal window, and projectile points capable of wounding elephant-sized prey were commonly found in association with proboscidean remains. The Bering Land Bridge connecting Asia to Alaska and an ice-free corridor providing passage between the Pleistocene ice masses of Canada seemed to provide a clear route of entry for Clovis colonists. However, recent archeological, paleoenvironmental, biological, and theoretical work largely questions the plausibility of these events. [source] Robusticity and sexual dimorphism in the postcranium of modern hunter-gatherers from AustraliaAMERICAN JOURNAL OF PHYSICAL ANTHROPOLOGY, Issue 1 2007Kristian J. Carlson Abstract Throughout much of prehistory, humans practiced a hunting and gathering subsistence strategy. Elevated postcranial robusticity and sexually dimorphic mobility patterns are presumed consequences of this strategy, in which males are attributed greater robusticity and mobility than females. Much of the basis for these trends originates from populations where skeletal correlates of activity patterns are known (e.g., cross-sectional geometric properties of long bones), but in which activity patterns are inferred using evidence such as archaeological records (e.g., Pleistocene Europe). Australian hunter-gatherers provide an opportunity to critically assess these ideas since ethnographic documentation of their activity patterns is available. We address the following questions: do skeletal indicators of Australian hunter-gatherers express elevated postcranial robusticity and sexually dimorphic mobility relative to populations from similar latitudes, and do ethnographic accounts support these findings. Using computed tomography, cross-sectional images were obtained from 149 skeletal elements including humeri, radii, ulnae, femora, and tibiae. Cross-sectional geometric properties were calculated from image data and standardized for body size. Australian hunter-gatherers often have reduced robusticity at femoral and humeral midshafts relative to forager (Khoi-San), agricultural/industrialized (Zulu), and industrialized (African American) groups. Australian hunter-gatherers display more sexual dimorphism in upper limb robusticity than lower limb robusticity. Attributing specific behavioral causes to upper limb sexual dimorphism is premature, although ethnographic accounts support sex-specific differences in tool use. Virtually absent sexual dimorphism in lower limb robusticity is consistent with ethnographic accounts of equivalently high mobility among females and males. Thus, elevated postcranial robusticity and sexually dimorphic mobility do not always characterize hunter-gatherers. Am J Phys Anthropol, 2007. © 2007 Wiley-Liss, Inc. [source] | |||||||||||||
