Can organic farmers be ‘good farmers’? Adding the ‘taste of necessity’ to the conventionalization debate

Recent decades have seen a rapid increase in the rate of conversion from conventional to organic farming, as organic farming shifted from an alternative production approach practiced by a small number of idealists, to the de facto alternative to mainstream conventional production. Although there has been considerable academic debate as to the role of agri-business penetration into the production and marketing chains of organic farming (‘conventionalization’), less is known about how the economic drivers of conventionalization are negotiated into practices at the farm level. Drawing on Bourdieu’s conceptualization of economic and cultural capitals, the direct connection between symbols of ‘good farming’ and the economic requirements of maintaining a viable farming business (i.e., the ‘taste of necessity’) is demonstrated. Findings indicate that conventional and organic farmers in the study sites identified a similar range of cultural symbols, but organic farmers emphasized different symbols within this range. This diversity and selectivity demonstrates the fragmentation and contestation of ideals resulting from economic challenges at the time of the study. Economic capital is important to the decision to consider conversion to organic farming, but formal conversion reflects re-weighting of forms of cultural capital. The author argues that recognition of the impact of economic pressures on conventional farming, which in the study sites often led to reduced input use rather than intensification, is missing from the conventionalization debate. The mainstreaming of organic farming production has presented conventional farmers with a set of alternative or re-weighted symbols and a crucible for reflexive consideration of their own standards and practices of farming.     

The fluid nature of water grabbing: the on-going contestation of water distribution between peasants and agribusinesses in Nduruma,Tanzania

This article contributes to the contemporary debate on land and water grabbing through a detailed, qualitative case study of horticultural agribusinesses which have settled in Tanzania, disrupting patterns of land and water use. In this paper we analyse how capitalist settler farms and their upstream and downstream peasant neighbours along the Nduruma river, Tanzania, expand and defend their water use. The paper is based on 3 months of qualitative field work in Tanzania. We use the echelons of rights analysis framework combined with the concept of institutional bricolage to show how this contestation takes place over the full spectrum of actual abstractions, governance and discourses. We emphasise the role different (inter)national development narratives play in shaping day-to-day contestations over water shares and rule-making. Ultimately, we emphasise that water grabbing is not a one-time event, but rather an on-going struggle over different water resources. In addition, we show how a perceived beneficial development of agribusinesses switching to groundwater allows them to avoid peasant-controlled institutions, avoiding further negotiation between the different actors and improving their image among neighbouring communities. This development illustrates how complex and obscured processes of water re-allocation can be without becoming illegal per se.     

Understanding the organization of sharing economy in agri-food systems: evidence from alternative food networks in Valencia

Despite the proliferation of sharing economy initiatives in agri-food systems, the recent literature has still not unravelled what sharing exactly entails from an organizational standpoint. In light of this knowledge gap, this study aims to understand which resources are shared, and how, in a heterogeneous set of sharing economy initiatives in the context of food and agriculture. Specifically, this study compares the organization of various forms of alternative food networks (AFNs), which are recognized to be frugal forms of sharing economy initiatives (i.e., locally based, small-scale and with limited use of information technology), in terms of leadership, bureaucracy, shared resources and participants’ engagement. Data from a comparative case study across 18 AFNs identify five sharing economy models of AFNs with distinctive shared resources and organizational mechanisms: consumer groups; commercial community gardens; as well as network-based, privately owned and publicly owned self-consumption community gardens. These models also display notable differences in terms of their origins, participants’ goals and constraints which, to some extent, may be associated to the nature of their organization. Findings inform policy-makers, AFNs’ leaders and stakeholders—especially those seeking to support innovative models towards sustainable transitions—on how to tailor institutional norms and develop networks to meet the heterogeneous needs of different typologies of sharing economy initiatives in agri-food systems.     

A cultural economy model for studying food systems

In 1984, William Friedland proposed a Commodity Systems Analysis framework for describing the stages through which a commodity is transformed and how it acquires value. He challenged us to think of commodities as entities with a social as well as a physical presence. Friedland's argument enriched the concept of commodity production, but it remains essentially a supply side perspective.Since then, many commentators have argued that power is shifting from producers to consumers. Furthermore, some are claiming that, contrary to much traditional Marxist thinking about how individuals find meaning through their productive capacities, it is now through consumption that individuals are identifying themselves. Given the significance of this view, it seems timely to extend Friedland's framework to incorporate the consumption perspective.In light of other claims that the distance between production and consumption is increasing, it is equally important to acknowledge the processes that structure the relationship between the two spheres. This entails using new retail geographical and cultural studies to explore further what takes place in distribution and exchange.This article describes a new model for understanding power in commodity systems, one that acknowledges the input and interests of a range of actors beyond the agricultural sector. The proposed cultural economy model also emphasizes a range of value adding processes that are wider than those that apply to commodity production.     

If they come, we will build it: in vitro meat and the discursive struggle over future agrofood expectations

According to recent literature in the sociology of expectations, expectations about the future are “performative” in that they provide guidance for activities, attract attention, mobilize political and economic resources, coordinate between groups, link technical and social concerns, create visions, and enroll supporters. While this framework has blossomed over the past decade in science and technology studies, it has yet to be applied towards a more refined understanding of how the future of the modern agrofood system is being actively contested and understood. I seek to redress this gap by using the sociology of expectations to explain the discursive topography surrounding in vitro meat, a nascent agrofood technology whereby processed meat products are developed from stem cells as opposed to live animals. In discussing the obstacles and challenges which confront the proponents of this technology, I utilize three key concepts from the sociology of expectations: (1) hype, (2) retrospective prospects, and (3) the role of myth, metaphor, and ideology. I find that despite sluggish results and financial setbacks, the controversial legacy of previous agrofood technologies, and persistent cultural skepticism, the core ideological justifications for in vitro meat have proven to be resilient in buoying the technology through rough discursive waters.

Challenging the populist perspective: Rural people's knowledge,agricultural research,and extension practice

Recent trends in agricultural science have emphasized the need to make local people active participants in the research and development process. Working under the populist banner “Farmer First”, the focus has been on bridging gaps between development professionals and local people, pointing to the inadequate understanding of insiders' knowledge, practices, and processes by outsiders. The purpose of this paper is to expose the paradox of the prevailing populist conception of power and knowledge, and to challenge the simple notion that social processes follow straightforward and systemic patterns and can thus be manipulated with a transfer of power from outside to inside. The authors view “knowledge” as a social process and knowledge systems in terms of a multiplicity of actors and networks through which certain kinds of information are communicated and negotiated, and not as single, cohesive structures, stocks or stores. The guiding phrase is “the analysis of difference”, which suggests that knowledge is multilayered, fragmentary, and diffuse, not unitary and systematized. It emerges as a product of the interaction and dialogue between different actors and networks of actors with conflicting loyalties who negotiate over “truth” claims and battle over contrasting images and contesting interests. The paper challenges those promoting Farmer First approaches to reassess how people in different agroecological and sociocultural contexts make sense of and deal with constraining and enabling processes related to research and extension; how they attempt, through recourse to various discursive means, to enroll one another in their various endeavors; and how they use relations of power in their struggles to gain access to and control of social and political space.

Zuni farming and united states government policy: The politics of biological and cultural diversity in agriculture

Indigenous Zuni farming, including cultural values, ecological and biological diversity, and land distribution and tenure, appears to have been quite productive and sustainable for at least 2000 before United States influence began in the later half of the 18th century. United States Government Indian agriculture policy has been based on assimilation of Indians and taking of their resources, and continues in more subtle ways today. At Zuni this policy has resulted in the degradation and loss of natural resources for farming, reduction in the number of Zuni farmers and their control over farming resources, individualization of rights in farmland, consolidation of farm fields, and declining biological diversity in agriculture. The Zuni Sustainable Agriculture Project with the Zuni Irrigation Association and the Zuni community, are now working to revitalize sustainable Zuni farming, based on traditional values, knowledge, and technology, combined with modern knowledge and technology where appropriate. The United States government can support these efforts through appreciation of the need for Zuni control and the potential value of cultural and biological diversity.     

Gene technology,food production,and public opinion: A UK study

In this paper, dimensions of the debate surrounding the application of gene technology to food production are discussed and a study assessing perceptions of the technology among a sample of the UK public (n = 1499) is reported. The general picture that emerges from the study is one of people expressing low familiarity with the technology, with more people associating it with high risks than with low risks, and more people expecting it to provide low benefits than high benefits. Attitudes towards different applications vary significantly, as does trust in different potential sources of information about the technology. It is also shown that attitudes can be predicted not only by estimates of risks and benefits but also by perceptions of the involvement of ethical issues, by the perceived need for the technology, and by the perceived likelihood of improvements it is likely to bring to the quality of life in the UK. The results are discussed in the context of the need for greater public information about the technology and the realization that communication of risks takes place within a complex network of societal relationships.Paul Sparks is a social psychologist at the Institute of Food Research, Reading, UK. He has studied at the Universities of Kent (BA) and Oxford (DPhil). His research interests include attitude theory, social influences on food choice, and social and moral dimensions of attitudes towards food consumption and food production methods.

How we see ourselves and how we see others

People see themselves differently from how they see others. They are immersed in their own sensations, emotions, and cognitions at the same time that their experience of others is dominated by what can be observed externally. This basic asymmetry has broad consequences. It leads people to judge themselves and their own behavior differently from how they judge others and those others' behavior. Often, those differences produce disagreement and conflict. Understanding the psychological basis of those differences may help mitigate some of their negative effects.     

Robotic milking technologies and renegotiating situated ethical relationships on UK dairy farms

Robotic or automatic milking systems (AMS) are novel technologies that take over the labor of dairy farming and reduce the need for human–animal interactions. Because robotic milking involves the replacement of ‘conventional’ twice-a-day milking managed by people with a system that supposedly allows cows the freedom to be milked automatically whenever they choose, some claim robotic milking has health and welfare benefits for cows, increases productivity, and has lifestyle advantages for dairy farmers. This paper examines how established ethical relations on dairy farms are unsettled by the intervention of a radically different technology such as AMS. The renegotiation of ethical relationships is thus an important dimension of how the actors involved are re-assembled around a new technology. The paper draws on in-depth research on UK dairy farms comparing those using conventional milking technologies with those using AMS. We explore the situated ethical relations that are negotiated in practice, focusing on the contingent and complex nature of human–animal–technology interactions. We show that ethical relations are situated and emergent, and that as the identities, roles, and subjectivities of humans and animals are unsettled through the intervention of a new technology, the ethical relations also shift.

Visualization of amino acid composition differences between processed protein from different animal species by self-organizing feature maps

Amino acids are the dominant organic components of processed animal proteins, however there has been limited investigation of differences in their composition between various protein sources. Information on these differences will not only be helpful for their further utilization but also provide fundamental information for developing species-specific identification methods. In this study, self-organizing feature maps (SOFM) were used to visualize amino acid composition of fish meal, and meat and bone meal (MBM) produced from poultry, ruminants and swine. SOFM display the similarities and differences in amino acid composition between protein sources and effectively improve data transparency. Amino acid composition was shown to be useful for distinguishing fish meal from MBM due to their large concentration differences between glycine, lysine and proline. However, the amino acid composition of the three MBMs was quite similar. The SOFM results were consistent with those obtained by analysis of variance and principal component analysis but more straightforward. SOFM was shown to have a robust sample linkage capacity and to be able to act as a powerful means to link different sample for further data mining.     

Sustaining production and strengthening the agritourism product: Linkages among Michigan agritourism destinations

Agricultural restructuring has disproportionately impacted smaller US farms, such as those in Michigan where the average farm size is 215 acres. To keep agricultural land in production, entrepreneurial Michigan farmers are utilizing agritourism as a value-added way to capitalize on their comparative advantages, their diverse agricultural products, and their locations near large, urban, tourist-generating areas. Using focus groups, this paper illustrates how entrepreneurial farmers have strengthened Michigan agritourism by fostering producer networks through brochures and web linkages, information sharing in refining the agritourism product, referrals to other agritourism businesses that serve different markets or offer different products, purchase linkages, and a regional approach to establishing agritourism destinations and increase visitation. Successful entrepreneurial, agritourism developers thus work cooperatively, rather than individualistically and competitively. Agritourism destinations facing stiff competition from alternative venues for leisure time and food purchases benefit from supportive linkages that help sustain a critical mass of producers who offer diverse goods, maintain land in agriculture, and thus, reinforce Michigans image for agritourism.
