The pre-Natufian Epipaleolithic: long-term behavioral trends in the Levant

Few cultural developments have taken on as much archeological significance as when people began living in villages and producing their own food. The economic, social, technological, and ideological transformations immediately preceding and following these changes were profound. Early models of culture change associated with pre-agricultural societies of the Levant focused on the sudden, late origin of settled farming villages triggered by climate change. Accompanying this new economic and living situation was durable stone-built architecture; intensified plant and animal use; a flourishing of art and decoration; new mortuary traditions, including marked graves and cemeteries; elaborate ritual and symbolic behavior-a new way of life. This new life style arguably had a slow start, but really took off during the Epipaleolithic period (EP), spanning more than 10,000 years of Levantine prehistory from c. 23,000-11,500 cal BP. The last EP phase, immediately preceding the Neolithic, is by far the best-studied in terms of its cultural and economic contributions to questions on the origins of agriculture.1-4 Recently, archeologists have considered the earlier parts of the EP to be more culturally dynamic and similar to the later phase (Natufian) than was previously thought.3-10 The earlier EP is increasingly seen as demonstrating the behavioral variability and innovations that help us to understand the economic, technological, and social changes associated with complex hunter-gatherers of the Natufian and farmers of the Neolithic. This paper traces the cultural and biological developments of the EP period leading up to the Natufian and considers the long-term trajectory of culture change, social complexity, and village life in the Near East.     

Transgene flow in Mexican maize revisited: Socio‐biological analysis across two contrasting farmer communities and seed management systems

The flow of transgenes into landraces and wild relatives is an important biosafety concern. The case of transgene flow into local maize varieties in Mexico (the center of origin of maize) has been intensively debated over the past 15 years, including legal, political, and environmental disputes fanned by the existence of a significant scientific controversy over the methods used for the detection of transgenes. The use of diverse approaches and a lack of harmonized methods specific to the detection and monitoring of transgenes in landraces have generated both positive and negative results regarding contamination of Mexican maize with genetically modified material over the years. In this paper, we revisit the case of transgene contamination in Mexican maize and present a novel research approach based on socio‐biological analysis of contrasting communities and seed management systems. Two communities were used to investigate how different social and biological factors can affect transgene flow and impact transgene spread in Mexico. Our results show the presence of transgenes in one community and thus support the position that transgenes are highly likely to be present in Mexican maize landraces. However, our work also demonstrates that the extent and frequency with which transgenes can be found will significantly depend on the societal characteristics and seed management systems of the local communities. Therefore, we argue that future analysis of transgene presence should include social research on the seed management practices in the sampling area so that more robust and comprehensive understandings and conclusions can be drawn.     

Projecting the effects of climate change on the distribution of maize races and their wild relatives in Mexico

Climate change is expected to be a significant threat to biodiversity, including crop diversity at centers of origin and diversification. As a way to avoid food scarcity in the future, it is important to have a better understanding of the possible impacts of climate change on crops. We evaluated these impacts on maize, one of the most important crops worldwide, and its wild relatives Tripsacum and Teocintes. Maize is the staple crop in Mexico and Mesoamerica, and there are currently about 59 described races in Mexico, which is considered its center of origin . In this study, we modeled the distribution of maize races and its wild relatives in Mexico for the present and for two time periods in the future (2030 and 2050), to identify the potentially most vulnerable taxa and geographic regions in the face of climate change. Bioclimatic distribution of crops has seldom been modeled, probably because social and cultural factors play an important role on crop suitability. Nonetheless, rainfall and temperature still represent a major influence on crop distribution pattern, particularly in rainfed crop systems under traditional agrotechnology. Such is the case of Mexican maize races and consequently, climate change impacts can be expected. Our findings generally show significant reductions of potential distribution areas by 2030 and 2050 in most cases. However, future projections of each race show contrasting responses to climatic scenarios. Several evaluated races show new potential distribution areas in the future, suggesting that proper management may favor diversity conservation. Modeled distributions of Tripsacum species and Teocintes indicate more severe impacts compared with maize races. Our projections lead to in situ and ex situ conservation recommended actions to guarantee the preservation of the genetic diversity of Mexican maize.     

Sustainability indicator systems within urban governance: Usability analysis of sustainability indicator systems as boundary objects

While sustainability indicator systems (SIs) have proven to be valuable rational tools for improving the availability of information related to the relationship of cities and communities to natural limits, the indicators movement has achieved limited instrumental uptake in policy. This paper begins from a recognition that instrumental use of sustainability indicator systems is rare. Greater potential impact exists for SIs designed to be much more attentive to their conceptual and political values within their particular social and political context. In other words, greater attention to what has been called the governance of indicator systems, or the ways in which SIs fit as policy tools within a multilevel and multiactor governance context, is key to increasing their utility. This is particularly true given the need for decisive policy change, or even the introduction of a new development path, which is asserted within the sustainability agenda.Understanding the real and potential utility of indicator systems within multiactor governance processes, in which their roles are primarily rhetorical, conceptual and political, is facilitated by thinking about indicator systems as boundary objects, tools which open up dialogue, information sharing, learning and consensus-building across different policy boundaries: between experts and nonexperts, formal government and different nongovernment actors, higher-order governments and lower-order governments. This paper offers a comparative analysis of three sustainability indicator systems in the North American context – Vancouver's Vital Signs (Vancouver Foundation), Seattle's Happiness Initiative, and LEED-ND (US Green Building Council) – all of which have shown some success in operationalizing a new policy boundary as a means of making conceptual and political contributions to governance practices. The specific boundaries operationalized, the different approach taken by each project, and the usability demonstrated by each project at that boundary in terms of salience, legitimacy and credibility, are assessed comparatively. In general, the trajectory in design and use of ecological and sustainability indicators demonstrates an increase in appetite, aptitude and numbers of channels for use in processes of governance; however, these factors vary with the local social–political opportunity structure. This analysis presents the advances made as well as the tradeoffs evident in these cases across the gamut of different forms of usability of nongovernmental indicator systems designed for use as boundary objects, and suggests a path forward for indicator work which aims to change policy, from a governance perspective.     

Archeological dendrochronology in the southwestern united states

Dendrochronology, the science of tree‐ring dating, is the most accurate and precise nondocumentary dating method available to researchers studying the recent past. Tree‐ring dates are accurate and precise to the year and sometimes the season, and have no associated statistical uncertainty or standard error. Other prominent archeological dating techniques that use natural materials (for example, radiocarbon and archeomagnetism) have been calibrated using dendrochronological samples. 1 It is this precision and accuracy that has allowed archeologists working in the southwestern United States to construct the most detailed chronologies in the world, and to explore a plethora of environmental, social, and behavioral questions regarding past human adaptation to the region.     

Values Mapping and Counter-Mapping in Contested Landscapes: an Olympic Peninsula (USA) Case Study

Indigenous peoples, local communities, and other groups can use counter-mapping to make land claims, identify areas of desired access, or convey cultural values that diverge from the dominant paradigm. While sometimes created independently, counter-maps also can be formulated during public participation mapping events sponsored by natural resource planning agencies. Public participation mapping elicits values, uses, and meanings of landscapes from diverse stakeholders, yet individuals and advocacy groups can use the mapping process as an opportunity to make visible strongly held values and viewpoints. We present three cases from the Olympic Peninsula in Washington State to illustrate how stakeholders intentionally used landscape-values mapping workshops to amplify their perspectives in attempts to further political outcomes. We combine geospatial analysis with qualitative data to explore ways that landscape-values mapping were used as a political tool and how social scientists engaged in similar efforts can defend the scientific integrity of results.     

Cuban Home Gardens and Their Role in Social–Ecological Resilience

Cuba’s political and economic isolation in today’s globalised world demands constant adaptation by its inhabitants. The Cubans’ capacity to adapt increases their ability to cope with change and to reshape local ecological and social systems, creating a more resilient system. Worldwide, home gardens are a community’s most adaptable and accessible land resource and are an important component in reducing vulnerability and ensuring food security. The role of Cuban home gardens in relation to political change and economic crisis was investigated in Trinidad de Cuba using standard ethnobotanical research methods. Major events, such as the collapse of the Soviet Union and the subsequent economic crisis as well as frequently changing Cuban policies on agriculture, food security, religious freedom and healthcare, have had an impact on household decision-making, influencing home garden composition and management. Social networking surrounding home garden produce plays an essential part in the continuous adaptation to change, aiming to increase a diversity of resources and strategies, hence resilience.     

Global climate change increases risk of crop yield losses and food insecurity in the tropical Andes

One of the greatest current challenges to human society is ensuring adequate food production and security for a rapidly growing population under changing climatic conditions. Climate change, and specifically rising temperatures, will alter the suitability of areas for specific crops and cultivation systems. In order to maintain yields, farmers may be forced to change cultivation practices, the timing of cultivation, or even the type of crops grown. Alternatively, farmers can change the location where crops are cultivated (e.g., to higher elevations) to track suitable climates (in which case the plants will have to grow in different soils), as cultivated plants will otherwise have to tolerate warmer temperatures and possibly face novel enemies. We simulated these two last possible scenarios (for temperature increases of 1.3°C and 2.6°C) in the Peruvian Andes through a field experiment in which several traditionally grown varieties of potato and maize were planted at different elevations (and thus temperatures) using either the local soil or soil translocated from higher elevations. Maize production declined by 21%–29% in response to new soil conditions. The production of maize and potatoes declined by >87% when plants were grown under warmer temperatures, mainly as a result of the greater incidence of novel pests. Crop quality and value also declined under simulated migration and warming scenarios. We estimated that local farmers may experience severe economic losses of up to 2,300 USOne of the greatest current challenges to human society is ensuring adequate food production and security for a rapidly growing population under changing climatic conditions.

These findings reveal that climate change is a real and imminent threat to agriculture and that there is a pressing need to develop effective management strategies to reduce yield losses and prevent food insecurity. Importantly, such strategies should take into account the influences of non‐climatic and/or biotic factors (e.g., novel pests) on plant development.     

Response to Drought Among Farmers and Herders in Southern Kajiado District, Kenya: A Comparison of 1972-1976 and 1994-1995

This article examines continuity and change in farming and herder communities' strategies for coping with food deficits in S.E. Kajiado District, Kenya, through a comparison of coping strategies reported in surveys conducted in 1977 and 1996. It provides empirical evidence of the dynamic responses that one rural society prone to recurrent drought-related food insecurity has made to the complex interactions between exogenous and local political, economic, social and demographic, and environmental processes. It demonstrates that although driving forces emanating from national and international scales create the broad context for developmental change, local processes mediate these. As these alter, so do the options available for coping with food insecurity. The availability of these options differs according to a person's age, gender, and socio-economic status. Such dynamism and differentiation is inherent in rural development and should inform development planners and those seeking to include monitoring of coping strategies as a component of famine early-warning systems.     

Politics And Gastropolitics: Gender And The Power Of Food In Two African Pastoralist Societies

Male-centred aspects of political behaviour have generally remained the explanatory and interpretive focuses in analyses of the social organization of African pastoralists. While recent work on African pastoralists has shed increasing light on the lives of women, I argue that key assumptions underlying anthropological models of male dominance in these societies have been insufficiently challenged. Drawing on recent approaches in gender and social organization that highlight the mutual constitution of domestic and political domains, I examine comparative material from two well-known pastoralist societies: the Samburu of northern Kenya and the Nuer of southern Sudan. In doing so, I suggest strong linkages between male-dominated 'political spheres' and areas of domestic life in which the role of women is more significant – particularly processes of domestic food distribution. In re-examining central facets of Samburu politics – which are best known through Paul Spencer's seminal analysis of the gerontocratic aspects of Samburu political life – I suggest that the status and identities of Samburu men are in fundamental ways defined through their relationship to women as providers of food within Samburu households. Comparative material from the Nuer suggests, additionally, the strategic use of food by women in influencing male 'political spheres'. In comparing these cases, I suggest a more general model through which domestic processes of food allocation as realms of female-centred social action may be seen to play a central role in the forms and processes of pastoral 'political' life.     

HIV infection and the meaning of condoms

Present day meanings associated with condom use among drug-using women and their long term sexual partners include: loss of male protection; violations of constructions of intimacy, fidelity, conjugal bonding, and female identity; illness; and death. Efforts to change condom use patterns must be based on increased vocational, educational, and social opportunities for women. HIV prevention efforts might profit from the design of safer sex interventions informed by the above meanings; intensified mass media campaigns; and a re-contextualization of attitudes, behaviors, and beliefs.     

Intraspecific variation in space use, group size, and mating systems of caviomorph rodents

Intraspecific variation in social systems is widely recognized across many taxa, and specific models, including polygamy potential, resource defense, and resource dispersion, have been developed to explain the relationship between ecological variation and social organization. Although mammals from temperate North America and Eurasia have provided many insights into this relationship, rodents from the Neotropics and temperate South America have largely been ignored. In this review we focus on reports documenting intraspecific variation in spacing systems, group size, and mating systems of caviomorphs. This large group of New World hystricognath rodents occupies a diverse array of habitats; thus, members of the same species potentially exhibit different social systems in response to different ecological conditions. Spatial patterns vary in response to a diverse array of factors, including predation, food availability, population density, and soil characteristics. Changes in group size typically correlate with changes in resource availability, particularly food. Mating systems generally reflect the ability of males to control access to females, which may depend on population density or food distribution. In general, social organization in caviomorphs fits predictions of resource-based models; however, most studies have been purely observational, involving small numbers of animals over short time periods and reporting qualitative rather than quantitative levels of ecological correlates. In future studies the use of molecular techniques and controlled, experimental manipulations can increase our understanding of intraspecific variation in caviomorph social systems. This understudied group of rodents offers excellent opportunities to provide insights into the influence of ecological conditions on behavior such as social systems.     

Climate change and maize yield in southern Africa: what can farm management do?

There is concern that food insecurity will increase in southern Africa due to climate change. We quantified the response of maize yield to projected climate change and to three key management options – planting date, fertilizer use and cultivar choice – using the crop simulation model, agricultural production systems simulator (APSIM), at two contrasting sites in Zimbabwe. Three climate periods up to 2100 were selected to cover both near‐ and long‐term climates. Future climate data under two radiative forcing scenarios were generated from five global circulation models. The temperature is projected to increase significantly in Zimbabwe by 2100 with no significant change in mean annual total rainfall. When planting before mid‐December with a high fertilizer rate, the simulated average grain yield for all three maize cultivars declined by 13% for the periods 2010–2039 and 2040–2069 and by 20% for 2070–2099 compared with the baseline climate, under low radiative forcing. Larger declines in yield of up to 32% were predicted for 2070–2099 with high radiative forcing. Despite differences in annual rainfall, similar trends in yield changes were observed for the two sites studied, Hwedza and Makoni. The yield response to delay in planting was nonlinear. Fertilizer increased yield significantly under both baseline and future climates. The response of maize to mineral nitrogen decreased with progressing climate change, implying a decrease in the optimal fertilizer rate in the future. Our results suggest that in the near future, improved crop and soil fertility management will remain important for enhanced maize yield. Towards the end of the 21st century, however, none of the farm management options tested in the study can avoid large yield losses in southern Africa due to climate change. There is a need to transform the current cropping systems of southern Africa to offset the negative impacts of climate change.     

OBPC Symposium: maize 2004 &; beyond—Can agricultural biotechnology contribute to global food security?

Summary Bioengineering approaches provide unprecedented opportunities for reducing poverty, food insecurity, child malnutrition, and natural resource degradation. Genetic engineering offers outstanding potential to increase the efficiency of crop improvement. Thus agricultural biotechnology could enhance global food production and availability in a sustainable way. Small farmers in developing countries are faced with many problems and constraints which biotechnology may assist. Yet, there are varying levels of opposition to the use of this technology in most countries and it is especially intense in Europe. While there is certain public apprehension with the use of bioengineering in food improvement, the primary hurdles facing this technology are the stringent and burdensome regulatory requirements for commercialization, opposition from the special interest groups, apprehension by the food industry especially with the whole foods, and trade barriers including rigid policies on traceability and labeling. Bioengineered crops such as soybean, maize, cotton, and canola with a few traits have already made a remarkable impaet on food production and environmental quality. But, in the developing world, bioengineering of crops such as bananas, cassava, yams, sweet potatoes, sorghum, rice, maize, wheat, millet, and legumes, along with livestock, can elearly contribute to global food security. However, the integration of biotechnology into agricultural research in developing countries faces many challenges which must be addressed: financial, technical, political, environmental, activism, intellectual-property, biosafety, and trade-related issues. To ensure that developing countries can harness the benefit of this technology with minimal problems, concerted efforts must be pursued to create an awareness of its potential benefits and to address the concerns related to its use through dialog among the various stakeholders: policy makers, scientists, trade groups, food industry, consumer organizations, farmer groups, media, and non-governmental organizations. Biotechnology holds great promise as a new tool in the scientific toolkit for generating applied agricultural technologies; however, per se it is not a panacea for the worlds problems of hunger and poverty.     

Feasting, Craft Specialization, and the Ritual Mode of Production in Small-Scale Societies

Economic intensification has been documented in a diversity of small-scale societies. The existing archaeological theory concerning such intensification has tended to privilege economic and political explanations and largely ignores social action and ritual performance as motivations for economic change. In this article, 1 use both ethnographic and archaeological data to argue that ceremonial feasting and the need for socially valued goods, which are critical for ritual performance and necessary for a variety of social transactions, create the demand that underwrites and sustains economic intensification in small-scale societies. Food for large-scale feasts is acquired through the intensification of food production and procurement targeted specifically for feasting, rather than from the surplus available from routine subsistence production. Large-scale demands for socially valued goods tend to result in specialization on the production of "extraordinary" material culture, which is characterized by two modes of circulation, in networks of social obligations or as offerings in sacred locations. [Key words.craft specialization, exchange, feasting, ritual]     

The Importance of Being Serious: Subjectivity and Adulthood in Kenya

While anthropological scholarship on the life course transitions of young people has aimed to contribute to theories of structure and agency, social reproduction and change, it has done so relatively independently from the anthropological literature on subject formation. This paper explores how subjectivity – how people feel, think, and experience – is implicated in grappling with life course transitions. It addresses how ‘being serious’ is considered a critical adult competency and its achievement delineates a key life transition that young women in western Kenya variously resent and value, resist and seek. The analysis illuminates ways in which people grapple with their own subjectivity as a problem as well as a project, and how such problems and projects of subjectivity are problems and projects of social reproduction. I argue that taking account of such subjective transformations can augment political economy analysis of meanings and modes of life.     

Migration in Archeology: The Baby and the Bathwater

Migration has been largely ignored by archeologists for the last two decades. Yet prehistoric demography and population studies are accepted as central concerns, and neither of these can be studied profitably without an understanding of migration. Recent books by Rouse and Renfrew have resurrected migration as a subject of serious analysis. It is proposed here that systems-oriented archeologists, in rejecting migration, have thrown out the baby with the bathwater. Traditional archeological approaches to migration fall short because a methodology for examining prehistoric migration must be dependent upon an understanding of the general structure of migration as a patterned human behavior. Aspects of such a structure are suggested and an application to a particular case in Eastern Europe is described.     

Young Chileans' Views of Citizenship: Findings From the First Generation Born After the Reinstitution of Democracy

Through a qualitative methodology, this study examines meanings attached to citizenship, barriers for citizenship, motivations for civic engagement, and aspirations as citizens in a sample (n = 71) of Chilean youth that grew up during the transition to democracy. The meanings youth attached to citizenship include membership, entitlement to rights and responsibilities, active participation, being informed, and voting. Participants perceived that practices of the political class, the economic system, and social disparities are barriers to exercising citizenship. They challenge the principles of a social order they consider unjust and advance proposals for social transformation that claim for social justice, reducing socio-economic disparities, discrimination, and bringing the political class closer to ordinary citizens. Findings reflect critical and cultural notions of citizenship. Contrasting their actual experiences with their aspirations for citizenship, participants feel politically inefficacious as they perceive they lack the power to influence the sociopolitical system. Implications for sociopolitical development and youth policy are discussed.     

Crop Specialization,Exchange and Robustness in a Semi-arid Environment

We compare the robustness of food supplies to annual variation in rainfall within two different agricultural systems: a generalist system with one type of agent who cultivates both maize and agave, and a specialist system composed of two types of agents who cultivate either maize or agave and are able to exchange. When mean rainfall is relatively high and less variable or relatively low and more variable, food supplies in the specialist system are more robust than in the generalist system. However, at intermediate levels of mean rainfall and variability, food supplies in the specialist system are less robust than those in the generalist system. Our analysis suggests that conflicts of interest and their associated costs constrain the development of specialization in some environments. When considering the robustness of social-ecological systems, it is important to consider “for whom a coupled social and ecological system is robust?”     

The construction of Dominican state power and symbolisms of violence*

Maurice Bloch has argued that, under certain circumstances, aspects of a particular cosmology can become an idiom for expressing and justifying the necessity of using bodily violence in relationships of domination and subordination. This article seeks to develop this key idea with the aid of historically and ethnographically specific material from the Dominican Republic. The author attempts to show that both hegemonic Dominican nationalist imagery and hegemonic Dominican masculinity imagery contain certain ‐ different ‐ ideas about conquest. These ideas have supplied idioms for the legitimation and exacerbation of state violence and terror. The article also argues that symbolic and social complexes familiar to anthropologists under the labels of ‘religion’, ‘nationalism’, and ‘gender’, can furnish idioms for the legitimation of the illegitimate. We should not primarily conceptualize and study forms of political violence as phenomena outside a daily and ritually constructed reality of a particular kind, but, on the contrary, as practices and meanings which belong to a cultural, social, and political logic.
