Human nature is a puzzling matter that must be analysed through a holistic lens. In this commentary, I foray into anthropology's biosocial dimensions to underscore that human relations span from microorganisms to global commodities. I argue that the future of social-cultural anthropology depends on the integration of evolutionary theory for its advancement. Ultimately, since the likelihood of novel zoonoses' emergence, digital ethnography could offer remarkable opportunities for ethical and responsible inquiries.

By means of a probabilistic mathematical model, we bring into discussion the origin of life as a stochastic process. We consider only the chance of information emergence in the proteome and genome under the ideal thermodynamic and chemical conditions. For a more realistic model, we used, as a parameter, the information amount in N. equitans genome, the simplest known nowadays, as the equivalent to the first living cell that could have emerged in primitive Earth. We estimated the probability of information (...) emergence by chance as being smaller than 10-500’000. Considering the necessary ideal conditions for information emergence, the probability of the origin of life would be even smaller. (shrink)

When making decisions about action to improve animal lives, it is important that we have accurate estimates of how much animals are suffering under different conditions. The current frameworks for making comparative estimates of suffering all fall along the lines of multiplying numbers of animals used by length of life and amount of suffering experienced. However, the numbers used to quantify suffering are usually generated through unreliable and subjective processes which make them unlikely to be correct. In this paper, I (...) look at how we might apply principled methods from animal welfare science to arrive at more accurate scores, which will then help us in making the best decisions for animals. I argue that a combined use of both a whole-animal measure and a combination measurement framework for assessing welfare will give us the most accurate answers to guide our action. (shrink)

This draft investigates Genetic Networks as a special case with comparisons to other networks. The intention is to discover the mapping between generic and abstract network properties and specific case studies.

Hering’s opponent-colors theory suggests that our color sensations are produced by three mechanisms: a red–green mechanism, a yellow–blue mechanism, and a white–black mechanism. The first two mechanisms give rise to our sensations of hued colors; the third mechanism gives rise to our sensations of hueless colors. Noticeably, whereas the pair of colors produced by each of the hued mechanisms do not mix to yield a phenomenal intermediate (i.e., there are no greenish reds, reddish greens, yellowish blues, or bluish yellows), the (...) colors produced by the hueless mechanism, white and black, do have a phenomenal intermediate—gray. This different behavior of the white–black mechanism poses a problem for Hering’s theory. Several attempts to fix this problem have been suggested. This paper focuses on the suggestion made by Paul Heggelund a century after Hering proposed his theory. In Heggelund’s amendment of Hering’s theory, the hueless colors are not confined to the one-dimensional gamut between black and white, but rather require two components for their full description: a light–dark (or luminous–black) component, where light and dark are mutually exclusive sensations, and a white component, which doesn’t have an opponent counterpart. Here I show that although Heggelund’s theory indeed provides a solution to the problem that the hueless colors pose to Hering’s theory, it is not self-consistent. I go on to revise Heggelund’s theory to obtain a consistent opponent-colors theory. (shrink)

The scientific study of socio-cultural phenomenon requires a translocation of topics elaborated from the social perspective of the individual to a rationally ordered rendition of processes suitable for comprehension from a scientific perspective. Scholarly curiosity seeded from exposure in the natural setting to economic, political, socio-cultural, evolutionary, processes dictates that study of the self, should be a science with a necessary place in the body of world literatures; yet it has proven difficult to find a perspective to contain discussions of (...) topics in a coherent manner for scientific approach: for example, anthropology, the study of mankind, finds difficulty elaborating definition for the orientation of study; it is a member of the same set that contains it. In this presentation, based on features indigenous to a supposed distant perspective that is exposed employing experiences of history and criteria of common sensory perception, it is conjectured that a civilization lifetime pathology is contemporarily active. Example is taken from philosophical and sociological discourses, modern science theory, medicine in pursuit of international health issues, to capture conceptually a role of motions of external agents occurred within the interval of observation, elaboration of concepts, choice of directions, as a source of paradox and confusion. In supposition that does not escape simple logic, ubiquitously appealing to the experience bound senses for understanding, hidden motions, common to both observer and observed, are hypothesized to render from a sense of familiarity, a continued frustration in attaining an understanding of the self and nature. A psychical seduction is proposed to exist, related to historical behaviors associated with centrism and asceticism, produces eccentric interpretations that are bound modernly to logical circular, centric geometrical reasonings; world conceptualizations are conjectured to acquire an avoidance of a state of ‘motionless’ rather than death within selection processes. Projection by the imagination upon the unknown is conjectured to result in a seduction by an active ‘live-wire” embodied to motions occurred to a distant surface. (shrink)

In an online, participatory class, we interpreted The Dream of the Tabby Cats knowing nothing of the dreamer beyond age and gender, and having none of the dreamer’s associations. Our interpretation included a series of predictions about the dreamer. When it was complete, we asked the bringer of the dream (who had until then been silent and was not visible to us) to give us more information about the dreamer. Later the dreamer herself gave us more information. Of six predictions (...) four were confirmed. The dreamer’s apartment is repeatedly disturbed and, each time, a new cat appears. This record is another iteration of an experiment that will be described more fully in the paper The Dream of the Six-Legged Dog: An Experimental System to Test Meaning, soon to be published. This iteration repeats and confirms the evidence given in that paper. AUDIO RECORD OF CLASS AVAILABLE: link is on first page of the paper you download from this page. (shrink)

(NOTE: This is a transcript of the class. FOR THE FULL PAPER, please click on "Maxson J. McDowell".) A complete transcript of an experiment performed within a class on dream interpretation. Knowing only the dreamers age and gender, we interpreted his dream from its text. Our interpretation included predictions about the dreamer's psychological issues, and about his defenses. It also identified a series of jokes within the dream which would tend to penetrate the dreamer's defenses. When we had finished our (...) 'blind' interpretation, the bringer of the dream gave us more information about the dreamer against which we tested the accuracy of our predictions. A paper on this experiment has been submitted for publication. A link to an AUDIO-RECORDING of this class is given on the first page of this transcript. (shrink)

Beginning with an examination of the recent Nature News centered on Harvard-Lancet-Mehra et al. COVID-19 research scandal, I put forth suggestions--for further debate--to safeguard the integrity of science in a time of crisis. In particular, I identify a subtle form of lying published as Nature news. Subsequently, drawing on Scarry's book "Thinking in an Emergency", I argue that slow reasoning and quick action (called for by crises) are not mutually incompatible; thinking can be transformed into conscious-reflex action by way of (...) practice (e.g. firefighters, emergency room physicians). More importantly, I call upon cognitive scientists, with their expertise in reasoning, intuition, habits, and actions, among others, to take a proactive role in crafting crisis preparedness programs for universities and science publishers so that we all can continue to rely on science for truth and facts.

Abstract: Without directly taking sides in the design/anti-design debate, this paper defends the following position: the assertion that biological evolution “is” design-free presupposes the possibility to model biological evolution in a design-free way. Certainly, there are design-free models of evolution based on cumulative selection. But “to model” is a verb denoting “modeling” as the process leading to a model. So any modeling – trivially – needs “previous human design.” Nevertheless, contrary to other scientific activities which legitimately consider models while ignoring (...) the process leading to them, evolution theory must take into account the human activity of modeling required by its corresponding models.

Industrial animal agriculture is a significant driver of climate change, habitat loss, and the ongoing extinction crisis, all of which will continue to accelerate as global demand for animal products grows. Plant-based alternatives to animal products, which have existed for over a thousand years, offer a potential solution to this problem, as the intersection of recent technological innovation and shifting capital investment trends have ushered in a new era of alternative proteins that are redefining food categories like meat, eggs, and (...) milk. To better understand these evolving food forms, their attendant technologies, and the opportunities they afford for ameliorating the impacts of industrial animal farming, this article provides a genealogy of plant-based alternative proteins, with a particular focus on the current era and the role that design principles like biomimicry and skeuomorphism play in reproducing the organoleptic properties (the sensorial, experiential aspects) of animal products. Comparing the alternative protein market to other markets in which more sustainable foods and energy have failed to displace their environmentally destructive counterparts, it concludes by considering if whether creating novel new protein forms, rather than imitating conventional animal products, may afford a more promising path toward transformation of the food system.

In 2009 the Roundtable on Sustainable Palm Oil established a conflict resolution mechanism to help rural communities address their grievances against palm oil companies that are RSPO members. This article presents the broadest ever comprehensive assessment of the use and effectiveness of the RSPO conflict resolution mechanism, providing both overviews and in-depth analysis. Our central question is: to what extent does the RSPO conflict resolution mechanism offer an accessible, fair and effective tool for communities in Indonesia to resolve conflicts with (...) companies? Our aim is not only to provide a ‘reality check’ of this mechanism but also to contribute to the wider debate on how communities can seek access to justice when engaged in intractable conflicts with palm oil companies. For data collection, we took three steps. First, we used our own database of 150 conflicts between communities and companies in Indonesia. We identified 64 conflicts that involved RSPO member companies, of which 17 prompted communities to convey their grievances to the RSPO’s conflict resolution mechanism. Second, we used the database of the RSPO, which handled 85 complaints against companies in Indonesia in the period 2009–2020. Third, we conducted fieldwork, in total, about 6 months of fieldwork and extensive interviews on three conflicts involving RSPO companies to identify mechanisms leading to both failed and successful instances of conflict resolution. For our assessment, we used three criteria to assess the conflict resolution mechanism of the RSPO: accessibility, procedural justice, and the outcomes of the process. We conclude that—on all counts—the conflict resolution mechanism is biased in favor of companies. The result of these biases is that the actual capacity of the RSPO’s mechanism to provide a meaningful remedy for rural communities’ grievances remains very limited. This unequal access to justice sustains conflicts between companies and communities over land. (shrink)

Music is a universal human activity. Its evolution and its value as a cognitive resource are starting to come into focus. This chapter endeavors to give readers a clearer sense of the adaptive aspects of music, as well as the underlying cognitive and neural structures. Special attention is given to the important emotional dimensions of music, and an evolutionary argument is made for thinking of music as a prelinguistic embodied form of cognition—a form that is still available to us as (...) contemporary music creators and consumers.

Approaches to environmental verification, broadly defined, including varieties of certification and testing, is always intended to change production processes, and cause structural changes. However, sometimes these approaches can differ substantially—based on values and objectives—and thus structure farming processes in varied ways. They can also affect nature-society relations, by determining what differences matter, emphasizing ways of assessing standards that are deemed important, and deciding whether those standards have been met. Here, I compare two types of environmental verification systems for organic and (...) “safe” or “clean” rice, one in northeastern Thailand and the other in southern Laos. The approach used in northeastern Thailand is designed predominantly to gain access to Europe and the United States markets, and is dependent on regular and detailed farm documentation, inspections, and interviews. The other is more of a residue testing and marketing system, one that also has important environmental implications and is being applied for rice from southern Laos. I call the first process-based verification, and the second product-based verification. It is contended here that we need to consider how environmental verification in different forms variously structures production systems, although there are also other important factors, such as China-Laos relations. Crucially, these practices variously affect cultivation and production practices, and thus have important environmental implications, whether fully intended or not. (shrink)

Urban dwellers’ food and nutritional wellbeing are both dependent on infrastructure and can be indicative of wider wellbeing in urban contexts and societal health. This paper focuses on the multiple relationships that exist between food and infrastructure to provide a thorough theoretical and empirical grounding to urgent work on urban food security and nutrition in the context of rapid urban and nutrition transitions in the South. We argue that urban systems and food systems thinking have not been well aligned, but (...) that such alignment is not only timely and overdue but also fruitful for both thematic areas of research and policy. We draw in particular on work within wider urban political economy and political ecology that can be classified as part of the ‘infrastructural turn’ that is influential with urban studies but little acknowledged within food studies. Drawing on these literatures helps us to better understand the interrelationships between people, things and ideas that make up both infrastructure and food systems. Policy, planning and research relating to both food and urban systems cannot afford to ignore such interlinkages, though much policy still operates on the neat assumptions of progressive connectivity to ‘the grid’ and formal food retail. Instead we argue how in many urban governance systems, a variety of hybrid mechanisms—on and off the grid, public and private formal and informal—better represent how urban residents, particularly the most marginalised, meet their everyday food and infrastructural needs along a continuum of gridded and off-grid access.

Media outlets, industry researchers, and policy-makers are today busily extolling new robotic advances that promise to transform agriculture, bringing us ever closer to self-farming farms. Yet such techno-optimist discourse ignores the cautionary lessons of past attempts to mechanize farms. Adapting the Social Construction of Technology framework, we trace the history of efforts to replace human labor with machine labor on fruit, nut, and vegetable farms in California between 1945 and 1980—a place and time during which a post-WWII culture of faith (...) in the beneficence of technoscience applications to agriculture reached an apex. The degree to which and forms whereby mechanization gains momentum hinges on whether, how, and among whom a technological frame for mimicking human capabilities and supplanting workers coalesces. These frames, we find, vary considerably across crops, reflecting complex interactions of biology, farmer and farm worker behavior, industry supply chains, agricultural research and development, financial flows, and beliefs about labor, race, gender, and immigration. To tease out these complex dynamics, we draw directly from archival evidence to follow the development of cultivation and harvest machines through four cases spanning a spectrum of outcomes—tomatoes, nuts, peaches, and lettuce. In comparing across these cases, we find that although agricultural engineers, scientists, and their boosters framed mechanization as a triumphal narrative of progress in ‘human vs. nature’ conflicts, this techno-optimist rhetoric camouflaged deeper ‘human vs. human’ conflicts, particularly among agribusiness, farmers, and farm workers. We conclude with several insights that this historical study brings to the study of agricultural automation today. (shrink)

Due to natural phenomena like global warming and climate change, agricultural production is increasingly faced with threats that transcend farm boundaries. Management practices at the landscape or community level are often required to adequately respond to these new challenges (e.g., pest migration). Such decision-making at a community or beyond-farm level—i.e., practices that are jointly developed by farmers within a community—can be aided by computing and communications technology. In this study, we employ a translational research process to examine the social and (...) behavioral drivers of adoption of smart and connected farm networks among commodity crop farmers in the United States. We implement focus groups and questionnaires to bring to the fore views on the use of digital technologies in collaborative contexts. We find that participating farmers are concerned with several issues about the potential features of the network (e.g., the ability to ensure data validity while maintaining data privacy) and the nature of their interactions with the various stakeholders involved in the network management. The participatory approach we adopt helps provide insights into the process of developing technologies that are both actionable and trusted by potential end users. (shrink)

This paper uses distinctions between differing senses of “private,” “public” and “political” in the United States to argue for the value of framing food issues as a collective problem that calls for broadscale demands for justice. We argue that food choices do not simply belong to the realm of private preferences and market transactions. Rather, they are a set of decisions that have systemic causes and public consequences. They are shaped and constrained by public policies that underwrite the transportation of (...) food over long distances as well as particular crops and foodstuffs, and by the vendors and advertisers who try to convince us to eat more of the foods they produce. Because the consequences of eating an abundance of empty calories are not easily remedied at the personal level, citizens need to demand public, systemic solutions, including better food information, youth food education, and a healthier food supply.

New entrant policy, literature, and research offers an important angle for exploring where dominant agrarianism is reproduced and contested. As new entrants seek access to land, finance, and expertise, their credibility is filtered through a cultural and policy environment that favors some farming models over others. Thus, seemingly apolitical policy tools geared at getting new people into farming may carry implicit norms of who these individuals should be, how they should farm, and what their values should entail. A normative gaze (...) of farming often masks the financial, cultural, labor relation, and land tenure dimensions that are the underlying drivers of agrarian change. This paper applies social reproduction theory to explore a diversity of social labor processes that new entrant farmers practice to arrive at the point of agricultural production. Interviews with new entrant and successor farmers in Britain (excluding Northern Ireland) are presented first, followed by an analysis of new entrant policy instruments over the last two decades in Scotland. We find that new entrant policy fails to engage with a crisis of social reproduction in the food system because of a commitment to agrarian ideals of the self-sufficient and entrepreneurial farmer. By inviting newcomers into a dynamic of increasing precarious and uncompensated labor, very often by way of family relations, new entrant policy may act as a form of “predatory inclusion.” We argue that to be successful in reproducing the agricultural sector, new entrant farmer policy must be first a policy at attending to relations in the social sphere. Recognizing and supporting the diversified strategies farmers take on to assemble land for production would not only drive more just policy, but set the conditions for a more adaptive food system.

This paper builds on prior critical scholarship on Agriculture 4.0—an umbrella term to reference the utilization of robotics and automation, AI, remote sensing, big data, and the like in agriculture—especially the literature focusing on issues relating to equity and social sustainability. Critical agrifood scholarship has spent considerable energy interrogating who gets what, how decisions get made, and who counts as a “stakeholder” in the context of decision making, questions relating to distributive justice, procedural justice, and representative justice, respectively. Less attention, (...) however, has been paid in this literature to the subject of recognition justice. Recognition justice asks the question, “Who are subjects of justice?” That query, however, is easily to oversimplify. As subjectivity is neither monolithic nor fixed, implied in these discussions are deeper questions having to do with the characteristics of one’s subjectivity that deserve moral recognition. This act of translation, from justice-in-theory to justice-in-practice, also complicates the evaluation of whether Agriculture 4.0 platforms are just, or not. These recognition justice tensions are explored by leveraging qualitative data collected through forty-two face-to-face interviews with individuals on farms located in the US states of Arizona, California, Colorado, New Mexico, and Wyoming who utilize these platforms. The study design intentionally oversampled for persons with disabilities, which highlights another distinguishing characteristic of the paper relative to critical Agriculture 4.0 scholarship. In addition to exposing certain ableist assumptions in these discussions, the sampling technique proved invaluable for interrogating how we think about labor, work, and leisure in agriculture. The paper specifically discusses how Agriculture 4.0, for example, shapes conceptions of what it means to be “able to work,” “willing to work,” “hard working,” etc. (shrink)

The United States prison system, the largest in the world, operates through both exploitative and rehabilitative modes of discipline. To gain political and public support for the extensive resources expended housing, feeding, and controlling its incarcerated population, the carceral state strategically emphasizes a mix of each mode. Agriculture in prisons is particularly illustrative. With roots in racial capitalism and the carceral state’s criminalization of poverty, plantation convict leasing system, work reform efforts, and punitive and welfarist carceral logics, prison agriculture embodies (...) explicit forms of exploitation and claims of rehabilitation. Accordingly, this article contextualizes and explains results from a nationwide study of state prisons within our framework of the disciplinary matrix. At least 662 adult state prisons have agricultural activities, including an array of animal, food, and plant production. We find that the drivers of these activities are financial, idleness reduction, reparative, and training. Our disciplinary matrix framework departs from conventional assignments of a particular activity to one disciplinary mode or the other and recognizes that any activity may be driven by different prison needs or philosophies. We investigate how different combinations of agricultural activities and drivers rely on discourses of deservingness to naturalize and reproduce structures of racialized, classed, and gendered control inside and outside prison, as well as the legitimacy of the prison system itself.

Conventional gender analysis of development policy does not adequately explain the slow progress towards gender equality. Our research analyses the gender discourses embedded in agricultural and rural development policies in Myanmar and Nepal. We find that both countries focus on increasing women’s participation in development activities as a core gender equality policy objective. This creates a binary categorisation of participating versus non-participating women and identifies women as responsible for improving their position. At the same time, gender (in)equality is defined exclusively (...) as a women’s concern. Such discourses, as constitutive practices, produce specific knowledge about rural women and new subjectivities that prescribe and govern them solely as subjects of development. Our research suggests that such a limited discursive practice invisiblises gendered power relations and structural and institutional issues, ultimately slowing progress towards gender equality. We demonstrate the importance of studying policy as discourse, beyond the effectiveness of policies or mainstreaming tools, and call for empirical evidence on the impact of these discourses on women’s subjectivities and lived experiences.

The páramos of Boyacá in Colombia are earmarked for delimitation to prevent the expansion of the agricultural frontier and protect endemic flora that contribute to water provision for cities. A varied conservation toolbox will be used, including the creation of protected areas for re-wilding and the ‘sustainable’ transitioning of livelihoods identified as environmentally destructive. Agriculture and cattle livestock farming has been identified for transitioning. Despite the negative discourse related to livestock holding, this paper argues that small-scale agropastoralism contributes to re-peasantisation (...) and provides the foundations for an agrobiodiverse conservation approach. Agropastoralism facilitates re-peasantisation through strong socio-economic networks, interconnected communities, the solidarity economy, and self-management of natural resources. Whilst, agropastoral mobility spatially binds social networks across large and disconnected spaces. Mobility is also fundamental to dynamic land access and pasture management, as it prevents over-grazing. This exemplifies how resilient socio-economic networks and mobile production strategies could be harnessed for agrobiodiversity, instead of land sparing and other sedentary ‘green’ economies. This paper makes conceptual contributions to ‘autonomy’ in re-peasantisation by empirically demonstrating the importance of mobile and flexible systems of production. It also makes a novel methodological contribution in applying a spatial lens that further unpacks how movement across the páramos facilitates autonomy and re-peasantisation. These themes are explored using interview data from 53 semi-structured interviews with key stakeholders and small-scale agropastoralists from across the páramos and field observation. The paper concludes by recommending a harnessing of agropastoral knowledge, to potentiate agrobiodiversity, for a more socio-ecologically just approach to farming and conservation in the páramos.

Promoting plant-based diets as a response to climate crisis has clear implications for producers of animal derived foods, but surprisingly little research considers their perspectives on this. Our exploration focused on farming strongly associated with meat production in Wales, UK. Mindful of polarised debates around plant-based diets, we considered dietary transition as an opportunity to produce for new markets. The first aim was to identify whether transition towards plant-based diets might trigger transformation of livestock agriculture. Findings indicate a potential trigger (...) event once livestock farmers are certain that consumer trends and climate mitigation require change. Livestock farmers who regard their meat as climate-friendly might resist transitions felt to unfairly disadvantage them. We then considered livestock farmers’ likely capacity to produce plant crops, and how this transformational capacity might be enhanced. Participants highlighted forms of financial and environmental inflexibility, plus social norms regarding “good” Welsh farmers, combining to make transformation risky. Transformational capacity might be enhanced through levering occupational and place attachments by portraying plant crops as a revival of historic practices from traditional farming landscapes. Improved linking capacity will also be beneficial, as producing for new markets requires connections to new supply chains, and learning across divisions within rural communities. We present these preliminary insights to livestock farmers’ attitudes and transformational capacity to inform future research with them to advance just agricultural transitions. Our study indicates potential to avoid confrontational discussion of dietary transition and we hope that others will pursue its focus on opportunities for farmers. (shrink)

The need for urgent, structural transformations to dominant food systems is increasingly recognized in research and policy. The direction these transformations take is in great part influenced by how the problem is framed and what future pathways become seen as plausible and desirable. Scientific knowledge and the organizations producing it hold considerable authority in suggesting what alternatives are or are not worth pursuing, ultimately shaping frames and in turn being shaped by them. This paper examines Brazil’s federal Agricultural Research Corporation (...) (Embrapa), a major contributor to technological advances that made Brazil into an agricultural powerhouse. We examine the ways in which Embrapa’s leadership has framed sustainable agriculture in its public communication and the wider implications for food systems transformation. Drawing from Embrapa news articles in the period 2015–2020, we identify four interrelated frames forming Embrapa’s prevalent position on sustainability. Our results show that while Embrapa promotes practices based on alternative approaches such as agroecology, its deeper framing often reflects the core assumptions driving dominant industrial food systems. This framing reinforces underlying logics of control, efficiency, and competition aligned with the productivist paradigm and excludes divergent perspectives that exist within the organization.

Traditional agricultural systems in Mediterranean Europe were characterised by diversity and multifunctionality, and polycultures played a fundamental role in them. Some of these farm systems and the traditional agricultural practices linked to them have now largely disappeared, but they are increasingly recognised as a valuable source of agroecological knowledge. In this study, we seek to recover the long-lost experience from a traditional Mediterranean intercropping system that combined the cultivation of vines and cereals. Using local historical resources available for a Catalan (...) village for the second half of the nineteenth century, we compare the characteristics and functioning of intercropping and monocultures of vines and cereals using socioeconomic and agrarian metabolism indicators, and discuss the advantages of the traditional intercropping system as an adaptation to the productive limitations of the agroecosystem (particularly in terms of soil quality and productivity, and availability of labour and draft force), but also as a peasant economy strategy that responded to a multifunctional balancing rationale. This way, this research contributes to recovering the knowledge and experience of a long-lasting traditional crop system that had been used until the second half of the twentieth century, and provides an understanding of the rationale and advantages of traditional Mediterranean crop systems beyond productivity and profit maximisation strategies.

The majority of food in the US is distributed through global/national supply chains that exclude locally-produced goods. This situation offers opportunities to increase local food production and consumption and is influenced by constraints that limit the scale of these activities. We conducted a study to assess perspectives of producers and consumers engaged in food systems of a major Midwestern city. We examined producers’ willingness to include/increase cultivation of local foods and consumers’ interest in purchasing/increasing local foods. We used focus groups (...) of producers (two groups of conventional farmers, four local food producers) and consumers (three conventional market participants, two locavores) to pose questions about production/consumption of local foods. We transcribed discussions verbatim and examined text to identify themes, using separate affinity diagrams for producers and consumers. We found producers and consumers are influenced by the _status quo_ and real and perceived barriers to local foods. We also learned participants believed increasing production and consumption of local foods would benefit their community and creating better infrastructure could enhance efforts to scale up local food systems. Focus group participants also indicated support from external champions/programs could support expansion of local foods. We learned that diversifying local food production was viewed as a way to support local community, increase access to healthy foods and reduce environmental impacts of conventional production. Our research indicates that encouraging producers and consumers in local food systems will be more successful when support for the local community is emphasized. (shrink)

At its core this book is concerned with logic and computation with respect to the mathematical characterization of sentient biophysical structure and its behavior. -/- Three related theories are presented: The first of these provides an explanation of how sentient individuals come to be in the world. The second describes how these individuals operate. And the third proposes a method for reasoning about the behavior of individuals in groups. -/- These theories are based upon a new explanation of experience in (...) nature, the construction of senses, and motile behavior. This new approach is developed from first principles to enable a rigorous and systematic explanation of the variety of associated intelligent behaviors. -/- Alongside this development is a further account that focuses upon the nature of our work. It discusses the existential aspects of scientific inquiry, its epistemology and logic. It seeks to clarify the nature of the mathematical characterization and computation of natural behaviors, dealing with questions in the foundations of logic. It explores methodological issues related to reduction and the refinement of ideas from intuition to formal logical structure. -/- In support of this inquiry we work toward the development of a calculus for biophysical construction and its dynamics. If successful this mechanics mathematically characterizes sensory and motile behavior. -/- Upon this foundation we propose a model of apprehension and explore how its products are processed by the organism. Finally, we develop a probabilistic theory that enables us to reason about inaccessible factors in group behavior. -/- The mechanics we propose suggests the design and physical realization of a new model of computation; one in which structure and the concurrency of action are a first-order consideration. -/- We identify opportunities for experimental verification of the theory and we suggest a proof of our results in practice by the identification of this mechanism, allowing the construction of machines that experience.

Although in theory social justice is considered as a core dimension of agroecological transitions, alternative food initiatives related to agroecology have been criticised for their exclusionary practices based on important social and economic biases. In this article, we adopt the lens of political intersectionality to study two cases of Agroecology-oriented Food Redistribution Coalitions in Spain that emerged to address the rising levels of food insecurity during the COVID-19 pandemic. We find that the coalitions represent a convergence of diverse social struggles, (...) placing intersectionally marginalized groups at the centre of their activism. However, we also uncover that coalition members participate in different ways depending on their socioeconomic profiles, which could perpetuate inequalities in organizational practices. One major point of tension is the need to balance the goal of providing access to healthy and sustainable food with the affordability of such produce. This leads to the adoption of hybrid food networks that include conventionally produced food. We also highlight that while the predominance of women in these coalitions reflects the unequal distribution of food-related care work in society, the collectivization of such work through AFRCs practices points to a transformation of gender relations. Territorialized alliances between actors from urban and rural settings and between urban centers and peripheries are established through the coalitions. However, such networks fall short on involving large numbers of agroecology-oriented initiatives and providing direct encounters between consumers and producers. Overall, the article underscores the importance of addressing intersecting inequalities within alternative food initiatives and argues that intersectional coalitions offer an intriguing example of how to promote such understanding and pave the way towards (more) just agroecological transitions.

Missing cooperation between farmers and nature conservationists is an obstacle to conflictive social-ecological transformation processes of agro-systems in Germany. Conflict psychology research shows that agonistic conflict frames play a crucial role in the parties’ response to and perception of conflicts. However, the role of conflict frames regarding farmers’ response to conservation conflicts in Germany, which are a recurrent expression of social-ecological transformation, is yet unclear. To address this knowledge gap, we investigate whether farmers have different agonistic conflict frames and whether (...) these are related to their perceptions of specific conflicts. To answer these questions, we developed a cluster analysis of farmers’ attitudes towards conflicts over river restoration in order to find indications for different conflict frames. We used data from a telephone survey from 2021 that was conducted with 300 farmers on the topic of river restoration conflicts. We captured conflict frames using four categories: rejection of others’ attitudes, perceived threat, perceived integrated potential, and delegitimization. In the second and third steps, we looked for differences between the groups with regard to the perception of concrete conflict and economic factors. The results of this explorative study show that it is possible to distinguish six agonistic conflict frames within the four categories. Moreover, the six groups show differences in how they perceive a concrete river restoration conflict. In five out of six groups, the perceived threat is indicated as high. The findings show that farmers have different perspectives on the conflict, indicating possible differences in needs and differences regarding the openness to communicative strategies. The groups differ in their concrete conflict perception, and only weak characterization with regard to the economic situation could be found. This knowledge can help policymakers and practitioners find practical and communicative strategies that constructively address farmers' different conflict frames. (shrink)

In the mid twenty-tens, many major food companies committed to sustainably source their priority ingredients, including North American commodity crops. With deadlines set for the decade’s end, companies joined multi-stakeholder initiatives and developed standards, metrics, and other assessment tools to help them track and drive progress. In short, they embarked on the sort of corporate supply chain governance that agri-food scholars have long studied. But how would this governance happen, especially in the commodity supply chains where companies knew and controlled (...) little about upstream production? Treating supply chain governance as not just a corporate undertaking but also the work of mid-level sustainability managers, this paper examines the practical skills and knowledge, or mētis, employed by managers in their efforts to win the support of colleagues, farmers, and other supply chain actors. This analysis provides insight into how and why food companies’ approaches to governing agricultural sustainability have changed since they set their 2020 sourcing goals. More broadly, it highlights the contingent nature of their governance. (shrink)

Recent discoveries of semantic compositionality in Japanese tits have enlivened the discussions on the presence of this phenomenon in wild animal communication. Data on semantic compositionality in wild apes are lacking, even though language experiments with captive apes have demonstrated they are capable of semantic compositionality. In this paper, I revisit the study by Boesch (Hum. Evol. 6:81–89, 1991) who investigated drumming sequences by an alpha male in a chimpanzee (_Pan troglodytes_) community in the Taï National Park, Côte d’Ivoire. A (...) reanalysis of the data reveals that the alpha male produced semantically compositional combined messages of travel direction change and resting period initiation. Unlike the Japanese tits, the elements of the compositional expression were not simply juxtaposed but displayed structural reduction, while one of the two elements in the expression coded the meanings of both elements. These processes show relative resemblance to blending and fusion in human languages. Also unlike the tits, the elements of the compositional expression did not have a fixed order, although there was a fixed distribution of drumming events across the trees used for drumming. Because the elements of the expression appear to carry verb-like meanings, the compositional expression also resembles simple verb-verb constructions and short paratactic combinations of two clauses found across languages. In conclusion, the reanalysis suggests that semantic compositionality and phenomena resembling paratactic combinations of two clauses might have been present in the communication of the last common ancestor of chimpanzees and humans, not necessarily in the vocal modality.

Sustainable Public Food Procurement (SPFP) is gaining recognition for its potential to improve the sustainability of food systems and promote healthier diets. However, SPFP faces various challenges, including coordination issues, actor dynamics, infrastructure limitations, unsustainable habits, and institutional resistance, among others. Drawing upon insights from the Multi-Level Perspective (MLP) on socio-technical transitions and the X-curve model on transition dynamics, this study investigates the role of transition intermediaries in facilitating SPFP-induced transformations in food systems. Focusing on four case studies in Spain, (...) we identify common barriers encountered in SPFP and analyse how distinct types of transition intermediaries contribute individually and collectively to address these challenges. Additionally, we explore how intermediary networks evolve throughout different phases of the transition process. Our findings reveal that SPFP barriers are systemic and interconnected, emphasizing the necessity of collective intermediation to overcome these obstacles. Furthermore, our results reveal how collective intermediation is orchestrated by pivotal intermediaries who mobilize diverse transition intermediaries, shaping multiple transition pathways. These intermediaries operate at both food system regimes and niches, challenging the conventional notion that transformative change can only originate from niche efforts. Lastly, we highlight the dynamic and flexible nature of intermediation in SPFP transitions, underscoring the importance of adaptability in strategies as these transitions evolve over time. Practical implications include the need for context-specific, adaptive approaches and strategies that leverage intermediary diversity. This research offers insights for policymakers, practitioners, and scholars into SPFP and broader transitions towards food systems transformation, fostering a more comprehensive understanding of these transition processes.

Abstract: -/- We present a teaching activity, whose aim is to enhance students’ understanding of color perception by introducing them to intersubjective color variations among normal perceivers. The approach can be used in different disciplines, including biology, philosophy, psychology, physics, or statistics, for different purposes and with college students having various levels of sophistication and scientific training.

Despite extensive evidence for its effectiveness, ECT remains the subject of fierce opposition from those contesting its benefits and claiming extreme harms. Alongside some reflections on my experiences of this treatment, I examine the case against ECT, and find that it appears to rest primarily on unsubstantiated claims about major ethical violations, rather than clinical factors such as effectiveness and risk.

Veterinarians are increasingly confronted with new technologies, such as Precision Livestock Farming (PLF), which allows for automated animal monitoring on commercial farms. At the same time, we lack information on how veterinarians, as stakeholders who may play a mediating role in the public debate on livestock farming, perceive the use and the impact of such technologies. This study explores the meaning veterinarians attribute to the application of PLF in the context of public concerns related to pig production. Semi-structured interviews were (...) carried out with pig veterinarians located in the Netherlands and Germany. By using an inductive and semantic approach to reflexive thematic analysis, we developed four main themes from the interview data: (1) the advisory role of the veterinarian, which is characterized by a diverse scope, including advice on PLF, generally positive evaluations and financial dependencies; (2) the delineation of PLF technologies as supporting tools, which are seen as an addition to human animal care; (3) the relationship between veterinarian and farmer, which is context-related, ranging from taking sides with to distancing oneself from farmers; and (4) the distance between agriculture and society, in the context of which PLF has both a mitigating and reinforcing potential. The present findings indicate that veterinarians play an active role in the emerging field of PLF in livestock farming. They are aware of and reflect on competing interests of different groups in society and share positions with different stakeholders. However, the extent to which they are able to mediate between stakeholder groups in practice seems to be constrained by external factors, such as financial dependencies. (shrink)

In the last 2 decades, the literature has documented the upsurge of community-driven processes of consumer-producer cooperation, which are alternative to the dominant food system. These organizational arrangements have been conceptualized differently, witnessing the growing importance of local communities in generating place-based solutions to the demand for organic, local, and sustainable food. Relying on a practice theory approach, this article delves into two key inquiries: first, what motivates individuals to become part of Civic Food Networks (CFNs) and how does this (...) influence the variety of food entering their households? And second, how does participation in a CFN impact people’s daily food practices, with a particular focus on diet diversification? We employ the term “civic food networks (CFN)” to underscore the significance of grassroots initiatives in the broader context of local food policies. This term also highlights the connections to other movements known for their potential for transformation, such as the solidarity economy, transition towns, and de-growth movements. Our analysis draws on a comprehensive qualitative approach, which includes participant observation, in-depth interviews, and a focus group involving members of the CSA _Naturalmente in Trentino_, situated in the North-Eastern part of Italy. The findings reveal that altering dietary habits poses various challenges both at the individual and institutional levels. This process involves the stabilization of ingrained habits, adjustments to daily routines, and the reinforcement of shared norms. Furthermore, it underscores the critical role of food policies in promoting sustainable eating practices. (shrink)

Jewish Agrarian Movements (JAM hereafter) in North America express the many different shapes and iterations of Jewish farming on the continent, grounded in historical perspectives that influence current practices and activities. From within this diversity, common threads emerge with much to contribute to agrarian social movements and scholarship. Jewish values of returning (_t_’_shuvah_), releasing (_shmitah_), and repairing (_tikkun_), along with theories of _doikayt_ (an anti-zionist movement around “hereness”) and radical diasporism, animate JAM’s critical engagement with agri-food systems. As researchers who (...) have both studied and participated in Jewish agrarianism in a variety of U.S. and Canadian contexts, we solidify a series of themes and tensions that emerge from JAM: diaspora and indigeneity, modernity and tradition, Jewish agroecological knowledge production, and lived religion. We argue that, while JAM has not yet been examined thoroughly within critical food scholarship, it has the potential to contribute to broader debates and frameworks within sub-fields such as radical food geographies, critical agrarianism, and decoloniality. Without consideration of JAM as a part the study of food and agriculture, there are risks of marginalization of farmers, activists and researchers of Jewish identity. (shrink)

This study investigates the increased commercialization of African indigenous vegetables (AIV)—former subsistence crops such as African nightshade, cowpea leaves and amaranth species grown mainly by women—from a feminist economics perspective. The study aims to answer the following research question: How does AIV commercialization affect the gendered division of labor, women’s participation in agricultural labor, their decision-making power, and their access to resources? We analyze commercialization’s effects on gender relations in labor and decision-making power and also highlight women’s agency. Based on (...) a mixed method design and analyzing household-level panel data and qualitative focus groups from Kenya, we observe an economic empowerment of women that we relate to women’s individual and collective strategies as well as their retention of control over AIV selling and profits. Yet, while we see economic empowerment of women through commercialization—how they broaden their scope of action and are empowered by generating revenue—that does not contribute to a redistribution of labor or land rights, which are key for gender equality, instead it increases women’s labor burden.

Despite the promise of new gene editing technologies (GETs) (e.g., CRISPR) in accelerating sustainable agri-food production, the social acceptability of these technologies remains unclear. Prior literature has primarily addressed the regulatory and economic issues impacting GETs ongoing acceptability, while little work has examined socio-cultural impacts despite evolving food policies and product commercialisation demanding input from various actors in the food system. Our systematic review across four databases addresses this gap by synthesising recent research on food system actors’ perspectives to identify (...) the key socio-cultural factors influencing GET acceptability. This review extends prior literature by including views from a more diverse range of actors (e.g., farmers and NGOs) and provides a better understanding of their perceived social benefits and concerns. We find food system actors perceive positive and negative impacts of using GETs in agriculture. These perspectives are often entangled in broader debates regarding sustainability and food systems issues (e.g., social justice). We discuss practical recommendations for policymakers, agri-food industry managers, and scientists to better align gene edited foods (GEFs) with food system actors’ values. GEF policy, development, and commercialisation must reflect social values such as collective wellbeing and transparency to improve actors’ acceptability. More research is required among marginalised food actors such as Indigenous and smallholder farmers. (shrink)
