    Crop Protection Between Sciences, Ethics and Societies: From Quick-Fix Ideal to Multiple Partial Solutions. [REVIEW]Coutellec Léo & Bernard Pintureau - 2013 - Journal of Agricultural and Environmental Ethics 26 (1):207-230.
    Crop protection has a very long history during which new methods have been developed whilst, at the same time, the older ones have retained their usefulness in certain conditions. The diversity of agricultural land and production has meant that it was futile to search for a unique and definitive approach or technical solution and, instead, the central concept has always been one of integration, during all the period of pre-Green Revolution and again today within what we call a (...)

    Plant viruses: A tool‐box for genetic engineering and crop protection.T. Michael & A. Wilson - 1989 - Bioessays 10 (6):179-186.
    Traditionally, plant viruses are viewed as harmful, undesirable pathogens. However, their genomes can provide several useful ‘designer functions’ or ‘sequence modules’ with which to tailor future gene vectors for plant or general biotechnology.The majority (77 %) of known plant viruses have single‐stranded RNA of the messenger (protein coding) sense as their genetic material. Over the past 4 years, improved in vitro transcription systems and the construction of partial of fulllength DNA copies of several plant RNA viruses have enhanced our ability (...)

    From One Community to Many: How Novel Objects in the Crop Protection Field Reveal Epistemic Boundaries.Antoine Blanchard - 2016 - Social Epistemology 30 (5-6):680-691.
    In this paper, I present a case study in the field of crop protection and discuss its epistemological implications. Through the advent of a novel class of objects at the end of the 1970s in Europe and the USA, namely plant elicitors that trigger the plant’s own defence reactions, we witness how dissent between epistemic communities appears where assimilation had been the rule. The convergence between the industry and the academia as a coherent “phytosanitary universe”, despite the fact (...)

    This paper examines the ethical andsocial questions that underlie the present UKdiscussion whether GM crops and organicagriculture can co-exist within a given regionor are mutually exclusive. A EuropeanCommission report predicted practicaldifficulties in achieving sufficientseparation distances to guarantee lowerthreshold levels proposed for GM material inorganic produce. Evidence of gene flow betweensome crops and their wild relatives has beena key issue in the recent Government consultation toconsult on whether or not to authorizecommercial planting of GM crops, following theresults of the current UK (...)

    Crop diversification and trade liberalization: Linking global trade and local management through a regional case study. [REVIEW]Evan D. G. Fraser - 2006 - Agriculture and Human Values 23 (3):271-281.
    Some models anticipate that liberalized agricultural trade will lead to increased crop diversity, while other models make the opposite claim. These positions were explored in southwestern British Columbia, Canada where, between 1992 and 1998, government subsidies and other measures designed to protect horticultural farmers were lifted, exposing these farmers to foreign competition. Public hearings on the future of agriculture provided an opportunity to tap the knowledge and experience of people affected by this transition. Analysis of transcripts from these hearings, (...)

    Facing food insecurity in Africa: Why, after 30 years of work in organic agriculture, I am promoting the use of synthetic fertilizers and herbicides in small-scale staple crop production.Don Lotter - 2015 - Agriculture and Human Values 32 (1):111-118.
    Food insecurity and the loss of soil nutrients and productive capacity in Africa are serious problems in light of the rapidly growing African population. In semi-arid central Tanzania currently practiced traditional crop production systems are no longer adaptive. Organic crop production methods alone, while having the capacity to enable food security, are not feasible for these small-scale farmers because of the extra land, skill, resources, and 5–7 years needed to benefit from them—particularly for maize. Maize, grown by 94 (...)

    Symbiont effector‐guided mapping of proteins in plant networks to improve crop climate stress resilience.Laura Rehneke & Patrick Schäfer - 2024 - Bioessays 46 (4):2300172.
    There is an urgent need for novel protection strategies to sustainably secure crop production under changing climates. Studying microbial effectors, defined as microbe‐derived proteins that alter signalling inside plant cells, has advanced our understanding of plant immunity and microbial plant colonisation strategies. Our understanding of effectors in the establishment and beneficial outcome of plant symbioses is less well known. Combining functional and comparative interaction assays uncovered specific symbiont effector targets in highly interconnected plant signalling networks and revealed the (...)

    The Importance of Biotic Sovereignty in the Context of Future Changes in the Legal Regulation of Genetically Modified Crops in the European Union and the Republic of Croatia.Ivica Kelam - 2022 - Filozofska Istrazivanja 42 (2):251-269.
    The “Lošinj Declaration on Biotic Sovereignty” is a novelty in the consideration of the environment and life in general and a unique document on a global scale. Until the advent of the Declaration, the environment was usually considered in an instrumentalist way, following the prevailing techno-scientific paradigm. The Declaration introduces biotic sovereignty as the starting point for the debate on GMOs, from which the harmfulness or potential benefits of genetic engineering can be assessed. The protection of biotic sovereignty should (...)

    “Support Your Local Invasive Species”: Animal Protection Rhetoric and Nonnative Species.Mona Seymour - 2013 - Society and Animals 21 (1):54-73.
    This article explores protection efforts that have arisen in the New York City metropolitan area around the monk parakeet, a nonnative bird that has achieved a broad distribution outside its native habitat range. In some urban regions in which populations are established, controversy has developed around the parakeets’ use of utility infrastructure and potential impacts on native species and agricultural crops. This case provides an opportunity to explore animal protection rhetoric about nonnative species, an understudied topic, considering the (...)

    Intellectual property rights and agricultural biodiversity: Literature addressing the suitability of IPR for the protection of indigenous resources. [REVIEW]Amanda B. King & Pablo B. Eyzaguirre - 1999 - Agriculture and Human Values 16 (1):41-49.
    Recent debate has focused on the use of intellectual property regimes for the protection of indigenous resources. Both domesticated crops and useful wild plants are shaped by indigenous knowledge and by their uses within indigenous cultures. This implies that the preservation of cultural systems is as important as the conservation of the associated biological resources. Intellectual property has been suggested as a means to protect indigenous resources from misappropriation, and to create increased investment in their conservation. Four recent books (...)

    Making plant pathology algorithmically recognizable.Cornelius Heimstädt - 2023 - Agriculture and Human Values 40 (3):865-878.
    This article examines the construction of image recognition algorithms for the classification of plant pathology problems. Rooted in science and technology studies research on the effects of agricultural big data and agricultural algorithms, the study ethnographically examines how algorithms for the recognition of plant pathology are made. To do this, the article looks at the case of a German agtech startup developing image recognition algorithms for an app that aims to help small-scale farmers diagnose plant damages based on digital images (...)

    A comparison of two IPM training strategies in China: The importance of concepts of the rice ecosystem for sustainable insect pest management. [REVIEW]James Mangan & Margaret S. Mangan - 1998 - Agriculture and Human Values 15 (3):209-221.
    Our study in China of two Integrated Pest Management (IPM) training programs for farmers shows that one is more effective than the other in reducing pesticide applications as well as in imparting to farmers an understanding of the rice ecosystem. The two training programs are based upon two different paradigms of IPM. This article uses a triangulated method of measuring concept attainment among farmer trainees in China as one measure of the effectiveness of training. Concepts of insect ecology brought about (...)

    Underground allies: How and why do mycelial networks help plants defend themselves?Zdenka Babikova, David Johnson, Toby Bruce, John Pickett & Lucy Gilbert - 2014 - Bioessays 36 (1):21-26.
    Most land plants associate with mycorrhizal fungi that can connect roots of neighboring plants in common mycelial networks (CMNs). Recent evidence shows that CMNs transfer warning signals of pathogen and aphid attack between plants. However, we do not know how defence‐related signaling via CMNs operates or how ubiquitous it is. Nor do we know what the ecological relevance and fitness consequences are, particularly from the perspective of the mycorrhizal fungus. Here, we focus on the potential fitness benefits for mycorrhizal fungi (...)

    A Drosophila melanogaster cell line (S2) facilitates post‐genome functional analysis of receptors and ion channels.Paula R. Towers & David B. Sattelle - 2002 - Bioessays 24 (11):1066-1073.
    The complete sequencing of the genome of the fruit fly Drosophila melanogaster offers the prospect of detailed functional analysis of the extensive gene families in this genetic model organism. Comprehensive functional analysis of family members is facilitated by access to a robust, stable and inducible expression system in a fly cell line. Here we show how the Schneider S2 cell line, derived from the Drosophila embryo, provides such an expression system, with the bonus that radioligand binding studies, second messenger assays, (...)

    The GMO Quandary and What It Means for Social Philosophy.Paul B. Thompson - 2014 - Social Philosophy Today 30:7-27.
    Agricultural crops developed using the tools of genetic engineering have become socially institutionalized in three ways that substantially compromise the inherent potential of plant transformation tools. The first is that when farming depends upon debt finance, farmers find themselves in a competitive situation such that efficiency-enhancing technology fuels a trend of bankruptcy and increasing scale of production. As efficiency increasing tools, GMOs are embedded in controversial processes of social change in rural economies. The United States, at least, has chosen not (...)

    Abstract: Tomatoes are part of the major crops in food security. Tomatoes are plants grown in temperate and hot regions of South American origin from Peru, and then spread to most countries of the world. Tomatoes contain a lot of vitamin C and mineral salts, and are recommended for people with constipation, diabetes and patients with heart and body diseases. Studies and scientific studies have proven the importance of eating tomato juice in reducing the activity of platelets in diabetics, which (...)

    Religion and Humor as Emancipating Provinces of Meaning.Michael Barber - 2017 - Cham: Springer Verlag.
    ​This book illustrates how non-pragmatic finite provinces of meaning emancipate one from pragmatic everyday pressures. Barber portrays everyday life originally, as including the interplay between intrinsic and imposed relevances, the unavoidable pursuit of pragmatic mastery, and the resulting tensions non-pragmatic provinces can relieve. But individuals and groups also inevitably resort to meta-level strategies of hyper-mastery to protect set ways of satisfying lower-level relevances—strategies that easily augment individual anxiety and social pathologies. After creatively interpreting the Schutzian dialectic between the world of (...)

    Creating Scientific Controversies: Uncertainty and Bias in Science and Society.David Harker - 2015 - Cambridge: Cambridge University Press.
    For decades, cigarette companies helped to promote the impression that there was no scientific consensus concerning the safety of their product. The appearance of controversy, however, was misleading, designed to confuse the public and to protect industry interests. Created scientific controversies emerge when expert communities are in broad agreement but the public perception is one of profound scientific uncertainty and doubt. In the first book-length analysis of the concept of a created scientific controversy, David Harker explores issues including climate change, (...)

    Are life patents ethical? Conflict between catholic social teaching and agricultural biotechnology's patent regime.Keith Douglass Warner - 2001 - Journal of Agricultural and Environmental Ethics 14 (3):301-319.
    Patents for genetic material in theindustrialized North have expandedsignificantly over the past twenty years,playing a crucial role in the currentconfiguration of the agricultural biotechnologyindustries, and raising significant ethicalissues. Patents have been claimed for genes,gene sequences, engineered crop species, andthe technical processes to engineer them. Mostcritics have addressed the human and ecosystemhealth implications of genetically engineeredcrops, but these broad patents raise economicissues as well.

    One of the starting assumptions in the debate over the ethical status of animals is that someone who is committed to reducing animal suffering should not eat meat. Steven Davis has recently advanced a novel criticism of this view. He argues that individuals who are committed to reducing animal suffering should not adopt a vegetarian or vegan diet, as Tom Regan an other animal rights advocates claim, but one containing free-range beef. To make his case Davis highlights an overlooked form (...)

    A “Practical” Ethic for Animals.David Fraser - 2011 - Journal of Agricultural and Environmental Ethics 25 (5):721-746.
    Abstract Drawing on the features of “practical philosophy” described by Toulmin ( 1990 ), a “practical” ethic for animals would be rooted in knowledge of how people affect animals, and would provide guidance on the diverse ethical concerns that arise. Human activities affect animals in four broad ways: (1) keeping animals, for example, on farms and as companions, (2) causing intentional harm to animals, for example through slaughter and hunting, (3) causing direct but unintended harm to animals, for example by (...)

    Understanding the gaps between the bilateral regularization of migration and workers’ rights: The case of agricultural migrant workers in Thailand.Sudarat Musikawong - 2022 - Theoretical Inquiries in Law 23 (2):289-325.
    ASEAN agricultural workers represent one of the most vulnerable groups of workers regardless of citizenship. While bilateral agreements focus on general migration governance mechanisms, the specifics of agricultural workers’ rights and protections fall outside their scope. Due to the seasonal nature of cross-border agriculture, these are flexible precarious workers readily available to employers in the borderlands that often do not invest in worker health and social security. The Article reveals how foreign migrant agricultural workers with and without work permits continue (...)

    On Epistemic Black Holes. How Self-Sealing Belief Systems Develop and Evolve.Maarten Boudry - unknown
    Some belief systems postulate intelligent agents that are deliberately evading detection and thus sabotaging any possible investigation into their existence. These belief systems have the remarkable feature that they predict an absence of evidence in their favor, and even the discovery of counterevidence. Such ‘epistemic black holes’, as I call them, crop up in different guises and in different domains: history, psychology, religion. Because of their radical underdetermination by evidence and their extreme resilience to counterevidence, they develop and evolve (...)

Most advisors interviewed accept that weather events are a risk for US Midwestern agriculture; however, they are more concerned about tangible threats such as crop prices. There is not much concern about climate change among agricultural advisors. (...)

    This paper examines farmer intentions to adapt to global climate change by analyzing responses to a climate change scenario presented in a survey given to large-scale farmers across the US Corn Belt in 2012. Adaptive strategies are evaluated in the context of decision making and farmers’ intention to increase their use of three production practices promoted across the Corn Belt: no-till farming, cover crops, and tile drainage. This paper also provides a novel conceptual framework that bridges a typology of adaptation (...)

    Food Biotechnology's Challenge to Cultural Integrity and Individual Consent.Paul B. Thompson - 1997 - Hastings Center Report 27 (4):34-39.
    Consumer response to genetically altered foods has been mixed in the United States. While transgenic crops have entered the food supply with little comment, other foods, such as the bioengineered tomato, have caused considerable controversy. Objections to genetically engineered food are varied, ranging from the religious to the aesthetic. One need not endorse these concerns to conclude that food biotechnology violates procedural protections of consumer sovereignty and religious liberty. Consumer sovereignty, a principle especially valued in this country, requires that information (...)

Climate migration creates a special setting for a duty to rescue. A duty to rescue is a moral rather than legal duty and imposes on a bystander to take an active role in preventing serious harm to someone else. This paper analyzes the idea of expanding a duty to rescue to climate migration. We address who should have (...)

    Focused on the impact of stringent intellectual property mechanisms over the uses of plant agricultural biodiversity in crop improvement, the article delves into a systematic analysis of the relationship between institutional paradigms and their technological contexts of application, identified as mass selection, controlled hybridisation, molecular breeding tools and transgenics. While the strong property paradigm has proven effective in the context of major leaps forward in genetic engineering, it faces a systematic breakdown when extended to mass selection, where innovation often (...)

    SAPs as novel regulators of abiotic stress response in plants.Jitender Giri, Prasant K. Dansana, Kamakshi S. Kothari, Gunjan Sharma, Shubha Vij & Akhilesh K. Tyagi - 2013 - Bioessays 35 (7):639-648.
    Stress associated proteins (SAPs), novel A20/AN1 zinc‐finger domain‐containing proteins, are fast emerging as potential candidates for biotechnological approaches in order to improve abiotic stress tolerance in plants – the ultimate aim of which is crop‐yield protection. Until relatively recently, such proteins had only been identified in humans, where they had been shown to be key regulators of innate immunity. Their phylogenetic relationship and recruitment of diverse protein domains reflect an architectural and mechanistic diversity. Emerging evidence suggests that SAPs (...)

    Following the rediscovery of Mendelian genetics, food supply pressures and the rapid expansion of crop varieties with defined performance characteristics, international systems were set up throughout the 20 C to regulate the trade of seed, the protection of intellectual property and the sale of productive varieties of key agricultural crops. These systems are a highly connected but largely linear set of processes. System changes are slow to be adopted due to the cascade of effects that structural alteration would (...)

    This paper explores the role of regulation and legislation on influencing the development and diffusion of technologies and methods of crop production. To do this, the change in pesticide registration under European Regulation 1107/2009 ‘Placing Plant Protection Products on the Market’ was followed through the UK’s agricultural system of innovation. Fieldwork included: a series of interviews conducted with scientists, agronomists and industry organisations; a programme of visiting agricultural events; as well as sending an electronic survey to British potato (...)

    Crisis in Swedish farmland preservation strategy.David Vail - 1986 - Agriculture and Human Values 3 (4):24-31.
    Since the late 1960's, a mix of government policies has prevented the loss of farmland in Sweden, “either to forest or asphalt”; these policies have also ensured the maintenance of soil fertility and groundwater resources. However, in Sweden as in several other European nations, a chronic and growing “grain glut” in recent years has undermined the economic logic of import protection and farm price supports—the principle means of promoting a sustainable agriculture. Mainstream economists, imbued with urban-biased and production-centered values, (...)

    “Utopia First!” A Machiavellian Conception of Solidarity in More's Utopia.Marie-Claire Phélippeau - 2018 - Moreana 55 (1):79-93.
    This paper shows how solidarity is one of the founding principles in Thomas More's Utopia. In the fictional republic of Utopia described in Book II, solidarity has a political and a moral function. The principle is at the center of the communal organization of Utopian society, exemplified in a number of practices such as the sharing of farm work, the management of surplus crops, or the democratic elections of the governor and the priests. Not only does solidarity benefit the individual (...)

    Proteinase inhibitor gene families: Strategies for transformation to improve plant defenses against herbivores.Clarence A. Ryan - 1989 - Bioessays 10 (1):20-24.
    Recent evidence indicates that the presence of serine proteinase inhibitors in plant leaves can reduce predation by insects. Plants can now be transformed with proteinase inhibitor genes with strong promoters to express the inhibitor proteins in relatively high levels at specific times. Inhibitors having variable specificities against digestive proteinases of insects and pathogens can now be assessed for their possible role(s) in natural plant defense and for their potential usefulness in protecting crop plants against herbivores.

    Current Agricultural Practices Threaten Future Global Food Production.Yongbo Liu, Xubin Pan & Junsheng Li - 2015 - Journal of Agricultural and Environmental Ethics 28 (2):203-216.
    In future decades, food demand for an increased population with elevated standards of living poses a huge challenge, particularly in the sense of the environmental impacts of agricultural systems. We have analyzed agricultural data from the past 50 years, and found that the current agricultural practices will have negative effects on global food production: total agricultural area has decreased since 2000, fertilizer and pesticide consumption increased while their efficiency decreased, and available water sources are already being used for irrigation. Expansion (...)

    Assessing the feasibility of biological control of locusts and grasshoppers in West Africa: Incorporating the farmers' perspective. [REVIEW]Hugo De Groote, Orou-Kobi Douro-Kpindou, Zakaria Ouambama, Comlan Gbongboui, Dieter Müller, Serge Attignon & Chris Lomer - 2001 - Agriculture and Human Values 18 (4):413-428.
    A participatory rural appraisal inthree West African countries examined thepossibility for replacing chemical pesticidesto control locusts and grasshoppers with abiological control method based on anindigenous fungal pathogen. The fungus iscurrently being tested at different sites inthe Sahel and in the humid tropics of WestAfrica. Structured group interviews, individualdiscussions, and field visits, were used toobtain farmers' perceptions of locust andgrasshoppers as crop pests, their quantitativeestimation of crop losses, and theirwillingness to pay for locust control. Farmersas well as plant (...) officers generallyperceived locusts and grasshoppers as importantpests that cause significant damage. Farmerswere aware of some of the risks of the use ofchemical pesticides, but not of the potentialalternatives. The use of the fungus in anoil-formulation and standard Ultra Low Volume(ULV) equipment was demonstrated, and theresults discussed with farmers. Theirimpressions of biological control werefavorable, and they expressed an interest inusing the technology. Farmers' expressedwillingness to pay for locust control is small,but not negligible. Locusts and grasshoppersare very visible pests and thus amenable topressure from farmers to local administrators,as well as by farmers' relatives in the city onthe national government. Therefore, politicalpressure for locust control is strong, althoughnational governments spend little on it,depending mostly on foreign donors. Donors areincreasingly worried about the environmentaleffect of the large amounts of chemicalpesticides used on locust control, and arepushing for more benign alternatives. Theresults of the present survey indicate thatthere may be a potential market for abiopesticide against grasshoppers and locustson cash crops in the humid areas. The potentialmarket in the Sahel depends on a reduction ofcosts or a subsidy of its price. This subsidycould be justified by the expected reduction inenvironmental and health costs when replacingchemical pesticides. Since donors are thecurrent purchasers of chemical pesticides forthe Sahel, they would also be expected to beinvolved in the purchase of the biologicalproduct. (shrink)
