Several global developments (e.g. diminishing production resources, growing demand for bio-energy) and numerous sector-wide crises (e.g. BSE, swine fever, dioxin) have led to a changing attitude of society towards the consequences of the food systems activities for social, economic and environmental issues, captured in the term of sustainability. Consumers in their role as final customers, and as a consequence also enterprises within agri-food supply chains, show increasing interest in the characteristics of food, and in turn, on the availability of related information and guarantees. Enterprises in agri-food supply chains are facing new expectations and are seeking to communicate social, economic and environmental performance of their business to customers within their supply chain and to consumers. New solutions for determination and communication of sustainability are needed for the agri-food sector, covering single aspects of sustainability as well as sustainability in a broader sense, including social, economic and environmental issues. Integrated, computer-based information services, since they are mainly building on existing systems, provide flexible solutions for enterprises to measure and evaluate sustainability of products throughout agri-food supply chains. Gained information on product characteristics might be used for decision support within enterprises as well as for communication of sustainable practices to customers and consumers, resulting in increased competitiveness of enterprises, supply chains and the sector by satisfying customers’ and consumers’ demands for information on the sustainability of a product. The present paper introduces a framework for developing information services for European pork chains using the three selected information domains food safety (representing social sustainability), quality (representing economic sustainability) and global warming potential (representing environmental sustainability). Resulting information models give an aggregated overview on information availability and exchange in European pork chains, additional information demands of possible service users and deficiencies in the existing information infrastructures. The paper supports different stakeholders involved in agri-food production, such as service developers, enterprise decision makers and management consultants, in developing enterprise- and chain-specific solutions which meet customers’ and consumers’ demands by providing appropriate sustainability information and guarantees. 相似文献

The growth in organic and local foods consumption has been examined using two different approaches to identify characteristics and motivations of food shoppers: market segmentation and economic models using multivariate analysis. The former approach, based on Means-end Chain theory, examines how intrinsic characteristics of foods affect food choices. The latter microeconomic approach examines economic constraints and extrinsic factors. This study demonstrates value in combining the two approaches to generate better empirical predictions of who buys organic and local food. It also supports a broader theoretical framework to explain behavior in terms of intrinsic and extrinsic motivations. Using US data, an adaptation of the Food Related Lifestyle model yields four consumer lifestyles segmented by intrinsic motivations related to food. Each consumer segment exhibits distinct organic and local foods consumption behaviors. A multinomial logit model is estimated to examine the probability of being in one of these four groups as a function of extrinsic variables and economic constraints. In support of Alphabet theory and Regulatory Focus theory, we find that inclusion of extrinsic factors improves prediction of behavior and the ability to explain why they buy organic and local foods. The extrinsic variables that significantly increase the probability of being in a particular consumer food lifestyle segment include: environmental concerns, health practices, race, the presence of a farmers’ market, and to a lesser degree, family composition and income. We also find regulatory focus is most pronounced among the most active organic and local food shoppers. 相似文献

Stakeholders in traditional dairy-producing states in the upper Midwest and Northeast hope that the boom in the organic milk market will offer family-scale dairy farms a means to escape the cost-price squeeze of the conventional food system. However, recent trends in organic dairy raise questions about whether organic dairy is conventionalizing, which is to say it is coming to resemble the conventional sector as shown in disparities of power in the value chain that pressure all participants to adopt more industrial practices. This paper reports the results of an exploratory qualitative study of whether and how the organic milk value chain in upstate New York is conventionalizing. Findings lend some support to the conventionalization hypothesis in that organic milk from the beginning has been produced, processed, and marketed as a commodity, and the federal regulations governing organic dairy have facilitated the replication of this commodity-based system. However, there is also evidence that some producers are responding to these pressures not by intensifying, but by going deeper into the alternative organic model, forging more direct and local relationships along the value chain and embracing principles of the organic movement. 相似文献

This paper addresses the development of organic agriculture in the Czech Republic, which is seen as a success story among
post-communist countries. The relatively short history of organic farming and specific contextual factors raises questions
about the nature and meaning of Czech organic farming. The goal of this study was to find out how farmers view their own practice,
interpret its symbolic value, and construct its content. This empirical study uses Q methodology aimed at the identification
of the collectively-shared perspectives belonging engaged actors. Data were gathered through semi-standardized interviews
with Czech farmers registered in official organic scheme. The analysis emphasized three components, which are considered as
three distinct perspectives possessed by organic farmers; that is, (1) organic farming as a way of life, (2) as an occupation,
and (3) as a production of food of an alternative quality compared to conventional food. Each viewpoint entails a different
understanding of what organic farming means; each then—when considered together—comprises the meaning of organic agriculture
in the Czech Republic. The presented classification of the farmers holding the viewpoints contributes to the ongoing theoretical
discussion regarding the nature of the current organic sector, its development and potential conventionalization. 相似文献

The contemporary US food systemis characterized by both an unprecedentedconcentration of corporate control as well as afragmentation of sourcing and marketingprocesses, introducing both new constraints andnew opportunities for more localized foodsystems. The purpose of our study is to explorethese issues by investigating three keyquestions. First, what are the key trends inthe US grocery industry? Second, how dodifferent kinds of food outlets choose,procure, and promote food products? Finally,what are the implications of recent trends inthe food retailing process for strengtheninglocal flows of the production, distribution,and consumption of food? Background informationon the grocery industry and the results ofseven open-ended interviews conducted withowners and managers of grocery stores in oneupstate New York county indicate that theretailing process differs in complex ways fromstore to store and in most aspects cannot beinferred from store type. The paper concludeswith a discussion of the implications of ourfindings for local food system efforts,specifically in terms of new collaborationsamong producers, distributors, retailers, andshoppers, who play an indispensable role indeveloping viable alternatives to increasingcorporate control. 相似文献

From farmers’ markets to primetime television cooking shows, notions of ‘knowing where our food comes from’ and ‘reconnecting’ with the sources of our food are now central to a range of contemporary cultural movements and popular media texts. While these ideas have primarily been mobilized by those with activist commitments to ethical and sustainable food production, they are also increasingly appearing in the media and marketing strategies of large agribusiness and retailing corporations, including those of the major Australian supermarkets. This paper explores some of the techniques currently used by major supermarkets to respond to criticisms about their food ethics, market control and relationship with producers. Using a case study of Australian supermarket Coles and its integration of its ‘Helping Australia Grow’ campaign into reality television cooking show, My Kitchen Rules, it will consider the textual practices of, and social media response to, Coles’ sponsorship and integrated advertising strategies of putting a ‘face’ to the farmers who produce the products found on supermarket shelves. By emphasizing to Coles customers that they, too, can ‘know where their food comes from’ and that their purchasing decisions support individual farmers and family farms rather than large conglomerates, these strategies help to locate Coles within a network of meanings that seek to both shift and contest negative perceptions of the supermarket chain’s corporate practices and food politics in ways that potentially complicate the activist discourses from which they draw. 相似文献

Qualitative and quantitative methods were used to investigate how shopping behaviors and environment influence dietary intake
and weight status among homeless Minnesotans living in food deserts. Seven focus groups (n = 53) and a quantitative survey (n = 255), using the social cognitive theory as the theoretical framework, were conducted at two homeless shelters (S1 and S2)
in the Twin Cities area. Heights, weights, and 24-h dietary recalls were also collected. Food stores within a five-block radius
of the shelters were evaluated for the price and availability of foods and compared to the Thrifty Food Plan’s market basket
prices (MBP). Results showed that almost 80% of the sample was overweight or obese, with women consuming less than the recommended
level for the fruits, vegetables, and milk food groups and excess for the fats/oils/sweets food group. Focus groups and participant
surveys indicated that the shelter infrastructure and surrounding community influenced the types of foods available, food
store access, and the foods purchased and consumed. Participants relied on food assistance programs, including food stamps,
to supplement their food supply; however, some felt the high food prices at neighboring stores limited food choice and that
food stamps did not adequately cover food costs. Results from the food store survey found the majority of food prices exceeded
Midwest or national MBP. To promote healthier dietary intake and weight status, community-based interventions and city planners
should aim to increase access to food through improved food availability and food access within the shelter environment and
surrounding community. 相似文献

The history of the controversy overrecombinant bovine growth hormone (rBGH) is exploredin terms of the issue of the potential robustness ofa consumption-driven ``new' politics of food andagriculture. It is noted that while the dominanthistorical traditions in the social sciences haveserved to discount the autonomous role that consumersand consumption play in modern societies, there hasbeen growing interest in consumption within foodstudies as well as other bodies of scholarship such aspostmodernism, social constructivism, socialcapital/social distinction, and environmentalsociology. A review of the shifting pattern ofdiscourses during the rBGH controversy shows thatconsumption-driven claims and politics played atangible, but relatively minor role. Even so, it issuggested that the rBGH experience along with paralleltrends in food politics (e.g., anti-pesticidecampaigns such as the ``Alar scare,' agribusinessattempts to intimidate opponents through fooddisparagement laws, conditions-of-productionprovisions of the World Trade Organization agreement)could make the consumption/consumer dimension of foodpolitics more important in the future. 相似文献

Focusing on the notion of competencies, the address explores important dimensions of human infrastructure for negotiating alternative agrifood systems. The analytical competencies emphasized are those of making connections and evaluating contradictions. Farm structure and food system connections with human health and consumer culture are chosen as examples. Examined in the context of social change strategies, relational competencies focus on new forms of food citizenship involving alternative organizational relationships between farmers, retailers, and customers. Ethical competencies are framed in relationship to the entire food system, to the valuing of non-market goods, and to linkages between ethics and emotions. Finally, aesthetic and spiritual competencies are considered as human capacities to connect agriculture and food with beauty and with sacramental living. 相似文献

Knowledge is a presumed motivator for changed consumption practices in ethical eating discourse: the consumer learns more about where their food comes from and makes different consumption choices. Despite intuitive appeal, scholars are beginning to illuminate the limits of knowledge-focused praxis for ethical eating. In this paper, we draw from qualitative interviews and focus groups with Toronto mothers to explore the role of knowledge in conceptions of ethical foodwork. While the goal of educating children about their food has become central to Canadian and American discourses of “good” mothering, we identify a paradoxical maternal expectation surrounding meat consumption: (1) to raise informed child consumers who know where their food comes from, and (2) to protect children from the harsh realities of animal slaughter. Rather than revealing the story behind the meat on a child’s plate, mothers seek to shield children from knowledge of meat production. Our analysis of the child consumer contributes to ethical eating scholarship and illuminates a larger paradox surrounding knowledge of meat in an industrialized food system. In the practice of feeding children, mothers confront the visceral discomforts of meat consumption; their reactions speak to discordant feelings involved with eating meat in a setting far-removed from the lives and deaths of animals. Ultimately, the paper illustrates the limits of consumer-focused strategies for food-system change that call on individual mothers to educate young consumers and protect childhood innocence, all while getting ethically-sourced meals on the table. 相似文献

As public and private resources are increasingly being directed towards the elimination of food deserts in urban areas, proper measurement of food access is essential. Amelioration has been approached through the use of farmers markets, virtual grocery stores, and corner store programs, but properly situating these assets in neighborhoods in need requires localized data on both the location and content of food outlets and the populations served. This paper examines the reliability of current techniques for identifying food deserts, and identifies some of the flaws in those approaches. Information derived from geographic information systems (GIS) mapping is the predominant means of determining food availability. In this study, food access in Bridgeport, CT, is examined utilizing both computer-based GIS mapping and on-the-ground observations. While the GIS output indicates generalized food accessibility issues, supplementation by survey data reduces the geographic extent of the food desert problem. Still, nearly 60,000 people (40 % of the population) reside in neighborhoods served only by small retailers who provide few healthy food options, and those at inflated prices. The high opportunity cost of travelling by bus to a major grocery store may outweigh the direct cost savings, and residents choose to consume locally available but unhealthy foods. 相似文献

Developing and developed countries alike are increasingly facing the difficult question of how to feed more people amidst a host of emerging demographic, environmental, and health challenges. At the same time, in addition to food quantity, increased attention is being given to food quality attributes, in particular nutrition and safety. This is especially evident in China, where concerns are on the rise regarding the ability of China's food production systems to deliver nutritious and safe food to a growing, urbanizing and more affluent population. These food and nutrition concerns come at a time when China is an increasingly influential actor within the global food security network through activities such as production, consumption and trade. We argue that China has the opportunity to increase food and nutrition security both nationally and globally through a comprehensive policy agenda that focuses on institutional reforms, investments for and in agriculture, productive social safety nets, mutually beneficial trade, and the exchange of know-how and technologies among developing countries and donors. This agenda will help China adapt its food production systems to the changing face of agriculture and to play a vital role in addressing the emerging challenges facing food and nutrition security within and beyond China in the coming decades. 相似文献

Urban agriculture (UA) is spreading within the Global North, largely for food production, ranging from household individual gardens to community gardens that boost neighborhood regeneration. Additionally, UA is also being integrated into buildings, such as urban rooftop farming (URF). Some URF experiences succeed in North America both as private and community initiatives. To date, little attention has been paid to how stakeholders perceive UA and URF in the Mediterranean or to the role of food production in these initiatives. This study examines the promotion and inclusion of new forms of UA through the practice of URF and contributes to the nascent literature on the stakeholder and public perceptions of UA. It seeks to understand how those perceptions shape the development of new urban agriculture practices and projects. Barcelona (Spain) was used as a Mediterranean case study where UA and URF projects are growing in popularity. Through semi-structured interviews with 25 core stakeholders, we show that UA is largely perceived as a social activity rather than a food production initiative, because the planning of urban gardens in Barcelona was traditionally done to achieve leisure and other social goals. However, several stakeholders highlighted the potential to increase urban fertility through URF by occupying currently unused spaces. As a result, the positive valuation of URF depends on the conceptualization of UA as a social or food production activity. In turn, such conceptualization shapes barriers and opportunities for the development of URF. While most UA-related stakeholders (e.g., food co-ops, NGOs) preferred soil-based UA, newer stakeholders (e.g., architects) highlighted the economic, social and environmental opportunities of local and efficient food production through innovative URF. 相似文献

The American food system has produced both abundance and food insecurity, with production and consumption dealt with as separate issues. The new approach of community food security (CFS) seeks to re-link production and consumption, with the goal of ensuring both an adequate and accessible food supply in the present and the future. In its focus on consumption, CFS has prioritized the needs of low-income people; in its focus on production, it emphasizes local and regional food systems. These objectives are not necessarily compatible and may even be contradictory. This article describes the approach of community food security and raises some questions about how the movement can meet its goals of simultaneously meeting the food needs of low-income people and developing local food systems. It explores the conceptual and political promise and pitfalls of local, community-based approaches to food security and examines alternative economic strategies such as urban agriculture and community-supported agriculture. It concludes that community food security efforts are important additions to, but not subsitutes for, a nonretractable governmental safety net that protects against food insecurity. 相似文献

Biopesticides are attracting interest as alternatives to conventional pesticides but without many of the non-target effects, promising a better record of safety and sustainability in pest control practices. In this article we summarize and discuss the current status and future promise of biopesticides, including how biopesticides use may increase the quality and safety of the food supply. 相似文献
