The potential for genetically modified (GM) crops to threaten biodiversity conservation and sustainable agriculture is substantial. Megadiverse countries and centers of origin and/or diversity of crop species are particularly vulnerable regions. The future of sustainable agriculture may be irreversibly jeopardized by contamination of in situ preserved genetic resources threatening a strategic resource for the world—s food security. Because GM crops are truly biological novelties, their release into the environment poses concerns about the unpredictable ecological and evolutionary responses that (...) GM species themselves and the interacting biota may express in the medium and long term. One of the consequences of these processes may be a generalized contamination of natural flora by GM traits and a degradation and erosion of the commonly owned genetic resources available today for agricultural development. GM plants carrying pharmaceutical and industrial traits will pose even more dangerous risks if released in the environment. (shrink)

Debates about the relationship between agricultural technology and the conservation of crop genetic diversity are often hampered by unclear vocabulary and imprecise data. Various interpretations of the terms “modern variety,” “local variety,” “hybrid,” and “green revolution” are first explored, and then evidence is examined regarding the effect of modern varieties on intra- and intercrop diversity, risk, input use, and farmer decision-making. The objective is to urge a more reasoned debate about the future of plant genetic resources.

There is no doubt that soybean is the most important crop for Argentina, with a planted surface that rose 11,000,000 hectares and a production of around 35,000,000 metric tons. During the 1990s, there was a significant agriculture transformation in the country, motorize by the adoption of transgenic crops (soy-bean, maize, and cotton) under the no-tillage system. The expansion of this model has been spread not only in the Pampas but also in very rich areas with high biodiversity, opening (...) a new agricultural border to important eco-regions like the Yungas, Great Chaco, and the Mesopotamian Forest. Transgenic cropping is a powerful technology. This produced relevant transformations over the environment and society where it is allowed. Migration, concentration of agribusiness, and loss of food sovereignty are some of the social results. Landscape transformation in the rural sector is evident, and the appearance of tolerance weeds to glyphosate is a reality. Nutrient depletion, soil-structure degradation, potential desertification, and loss of species are other consequences on the environmental level. (shrink)

Genetic modification of crop plants is frequently described by its proponents as a continuation of the ancient process of domestication. While domestication, crop breeding, and GM all modify the genomes and phenotypes of plants, GM fundamentally differs from domestication in terms of the biological and sociopolitical processes by which change occurs, and the subsequent impacts on agrobiodiversity and seed sovereignty. We review the history of domestication, crop breeding, and GM, and show that crop breeding and GM (...) are continuous with each other in many important ways, but represent a momentous break from domestication because they move plant evolution off of farms and into centralized institutions. The social contexts in which these processes unfold dictate who holds rights to germplasm and agricultural knowledge, shape incentives to effect particular kinds of changes in our crops, and create or constrict biodiversity. Presenting GM as a continuation of domestication puts forward a false equivalency that fundamentally misrepresents how domestication, crop breeding, and GM occur. In doing so, this narrative diminishes public understanding of these important processes and obscures the effects of industrial agriculture on in situ biodiversity and the practice of farming. This misrepresentation is used in public-facing science communication by representatives of the biotechnology industry to silence meaningful debate on GM by convincing the public that it is the continuation of an age-old process that underlies all agricultural societies.

The Svalbard Global Seed Vault provides a backup of seed collections from genebanks around the world. It’s unique character has made it iconic in the public imagination as a ‘Noah’s Ark’ for crop plants. Its remote location and strict controls on access have, however, also lent it an air of mystery, swirling with conspiracy theories. In this paper, I first clarify the aims of the Vault, the history of its development and the policies and practices of its current operation. (...) Given concerns around its potential links to the biotechnology industry, I go on to ask whether GM crops are currently stored in the Vault. Presenting several reasons for why GM crops are formally excluded, while indicating the potential for both change and unintentional contamination, I am compelled to question whether GM crops should be excluded. Answering this requires an interrogation of their potential conservation value as modern contributors to crop biodiversity. In exploring this issue, I suggest that there has been surprisingly little discussion of the moral status and conservation value of bio-technological crop plants and indeed, of how we care for all the techno-lifeforms we are currently engaged in co-creating. I suggest that these are becoming important issues as biotechnological techniques and applications begin to rapidly evolve and diversify. Emphasizing the scope for a refreshed interdisciplinary research agenda exploring the interface between biotechnology and biodiversity conservation, I conclude the article by proposing new concepts of synbiodiversity and symbiodiversity to encourage further debate.

In Vanuatu, small-scale farmers’ subsistence still largely relies on the sustainable use and maintenance of a wide-ranging biodiversity out of which root and tuber crops provide the bulk of daily subsistence. In neighboring countries, foreign influence since the first European contacts, further associated changes and the introduction of new crop species have induced a loss of cultivated diversity. This paper presents a baseline study of the diversity of root and tuber crops in ten communities throughout Vanuatu. In a (...) context where the smallholders’ agrosystems are increasingly considered as key components for the global conservation of crop genetic resources, this study provides clues to better understand the effective roles of biodiversity in traditional agrosystems. It also provides insights on the rationale behind the constitution of agricultural portfolios and discusses how the cultivated diversity allows communities to cope with changes and pressures. The paper also shows that recently introduced crops neither seem to have compromised agricultural diversity nor drastically changed the agrosystems in Vanuatu. On the contrary, such crops are used by farmers to strengthen the resilience of their agrosystems. A discussion then presents the idea of continuity through change and novelty as a critical factor for resilience. The paper concludes by discussing the role of indigenous agriculture and culture in ensuring food security and in development strategies in a larger context. (shrink)

The paper discusses conflicts in perceptions of GM crops illustrating the complexities of GM debates and applications of the concept of sustainable development. The concept consists of three discourses that both opponents and supporters of GM crops refer to in their analyses: environmentalism, social and economic development and the two sub-issues of sustainable development—biodiversity loss and food security. This creates a unique situation when both proponents and opponents of GM food use the same framework of sustainable development to support (...) their arguments and do not reach a common ground. This will be illustrated by a review of the arguments brought by these two groups. (shrink)

In public debates, agricultural biotechnology is almost invariably discussed as a potential threat to the environment and to human health. Without downplaying the risks associated with this technology we emphasize that if properly regulated, it can be a forceful tool to solve environmental problems and promote human health. Agricultural biotechnology can reduce environmental problems in at least three ways: it can diminish the need for environmentally damaging agricultural practices such as pesticides, fertilizers, tillage, and irrigation. It can reduce the land (...) area needed for agriculture, thus reducing the CO2 effect of agriculture and improving biodiversity. It can produce energy in a CO2-neutral way (especially if new technologies involving the cultivation of microalgae become successful). Furthermore, agricultural biotechnology can have positive effects on human health by decreasing occupational and dietary exposure to pesticides, improving the nutritional value of food, and producing pharmaceuticals more efficiently. We argue that those who wish to give high priority to environmental goals cannot afford any longer to be mere onlookers while others decide the future directions of agricultural biotechnology.

Southern Appalachia is unique among agroecological regions of the American South because of the diverse environmental conditions caused by its mountain ecology, the geographic and commercial isolation of the region, and the relative cultural autonomy of the people that live there. Those three criteria, combined with a rich agricultural history and the continuance of the homegardening tradition, make southern Appalachia an area of relatively high crop biodiversity in America. This study investigated the history and survival of traditional heirloom (...) vegetable crops in western North Carolina and documented 134 heirloom varieties that were still being grown. I conducted interviews with 26 individuals from 12 counties in western North Carolina. I used a snowball sampling method to identify individuals or communities that maintained heirloom vegetable varieties, and used the “memory banking” of farmers’ knowledge as a strategy to complement the gathering of seed specimens. Most of the varieties were grown and saved by homegardeners; beans were the most numerous. Results indicate that usually only one or two individuals in a community maintained significant numbers of heirloom varieties and that many communities have lost their heirloom vegetable heritage altogether. The decline of the farming population combined with a lack of cultural continuance in family seed-saving traditions threatens the ability of communities to maintain crop biodiversity. Some of the cultivars may represent the last (small) populations of endangered varieties. (shrink)

Industrialized agriculture currently substitutes many of the ecological functions of soil micro-organisms, macroinvertebrates, wild plants, and vertebrate animals with high cost inputs of pesticides and fertilizers. Enhanced biological diversity potentially offers agricultural producers a means of reducing the cost of their production. Conservation of biodiversity in agricultural landscapes may be greatly enhanced by the adoption of certain crop management practices, such as reduced pesticide usage or measures to prevent soil erosion. Still, the vast monocultures comprising the crop (...) area in many Canadian agricultural landscapes are often of limited conservation value, thus the inclusion of appropriate wildlife habitat in and around arable lands is a fundamental prerequisite for the integration of wild species within agricultural landscapes. This review of current literature considers the potential for non-crop areas within agricultural landscapes to be reservoirs of agronomically beneficial organisms including plants, invertebrates, and vertebrate species. Non-crop habitats adjacent to crop land have been identified as significant for the maintenance of plant species diversity, for the conservation of beneficial pollinating and predatory insects, and as essential habitat for birds. A key component for enhancement of biodiversity is the reintroduction of landscape heterogeneity by (1) protection and enhancement of key non-crop areas, (2) smaller fields and farms, and (3) a greater mixture of crops, through rotation, intercropping and regional diversification. The benefits of increased biodiversity within arable lands are reviewed for various species groups. In the Canadian context, any serious attempt to derive significant agronomic benefit from increased biodiversity will require considerable changes in the agricultural programs and policies which shape mainstream industrialized agriculture. The problems of crop depredation by vertebrate species, weed and insect competition, which still represent significant impediments to the creation and proper management of wildlife habitat, are also discussed.

The significance of enset for thefood and livelihood security of ruralhouseholds in Southwestern Ethiopia, where thiscrop is the main staple, raises two majorquestions. The first concerns the relatedissues of household food security andlivelihood security and the contribution of theenset farming and food system in achievingthese. The second deals with the issue ofbiodiversity in enset cultivation. What roledoes biodiversity play in food and livelihoodsecurity and how is it perceived and measured?To answer the latter question, it is necessaryto look at the (...) issue of classification of ensetvarieties, comparing indigenous and scientificclassifications. In answering the questions, aninterdisciplinary approach is used, and bothetic and emic perspectives are applied. Agender perspective is applied as well becauseof the gendered division of labor in ensetcultivation and the gendered nature ofindigenous knowledge. The analysis draws mainlyon the findings of a recent study on ensetcultivation in Ethiopia [Negash PhD thesis,Wageningen University, The Netherlands]. Thefindings show that enset farming guaranteeshousehold food security to a large extent, butthat household livelihood security depends onthe cultivation of additional crops andhousehold ownership of livestock and otherassets. It was also found that maximizingdiversity in enset is of importance to farmers,and that the farmers' classification of ensetvarieties yields a finer grid than theclassification of enset clones on the basis ofmolecular analysis.

Climate change is considered as the global challenge in the 21st century. Anthropogenic activities have directly led to an immense increase in green house gas emissions mainly carbon dioxide that contributes mainly in the warming of atmosphere. The concentration of carbon dioxide is expected to rise twice as high as those existing in pre-industrial period, within the next century. Pesticides are the biological pollutants, which are being used by the man to kill the pests for increasing the yield of many (...) crops and insect vectors to control the spread of disease. The tremendous use of pesticides has caused severe health hazards to organisms including human beings due to climate change. Excessive use of pesticides may lead to the destruction of biodiversity. Many birds, aquatic organisms and animals are under the threat of harmful pesticides for their survival. The pesticides effects are lessen by organizing awareness program among the farmers, gave special training to them regarding consequences of pesticides, their screening and monitoring methods.

The coexistence of genetically modified (GM) crops and non-GM crops is a myth because the movement of transgenes beyond their intended destinations is a certainty, and this leads to genetic contamination of organic farms and other systems. It is unlikely that transgenes can be retracted once they have escaped, thus the damage to the purity of non-GM seeds is permanent. The dominant GM crops have the potential to reduce biodiversity further by increasing agricultural intensification. There are also potential risks (...) to biodiversity arising from gene flow and toxicity to nontarget organisms from herbicide-resistant (HT) and insect-resistant (Bt) crops. Unless whole regions are declared GM agriculture free, the development of distinct systems of agriculture (GM and non-GM) will be impossible as GM agriculture emerges at the expense of all other forms of production.

AbstractIn many cultures, interactions between humans and plants are rooted in what is called “relational values”—values that derive from relationships and entail reciprocity. In Mexico, biocultural diversity is mirrored in the knowledge and use of some 6500 plant species and the domestication of over 250 Mesoamerican native crop species. This research explores how different sets of values are attributed to plants and how these influence management strategies to maintain plant resources in wild and anthropogenic environments. We ran workshops in (...) two communities in a highly biodiverse region in western Mexico, to ascertain the values and management activities related to important plant resources. The relationship between values attributed to plants and management activities was examined through redundancy analysis. A total of 180 plant resources were mentioned during the workshops, with a broad spectrum of values attributed to them, including material, non-material, and regulatory dimensions. We divided plant management strategies into three general categories of increasing intensity and complexity. We found that participants in the Indigenous community value and manage more wild plant resources than people in the non-Indigenous community. We also identified relationships between plant resource values and the type of management performed; for example, more intensive forms of management, such as sowing seeds, were used for seasonal plants that had a food value. By valuing and managing different sets of plant resources from forest, agricultural plots, and home gardens, people enabled multi-functional landscapes to form, illustrating a key feature of relational values in agroecosystems, which promotes both conservation and domestication of plants.

A major programme of irrigated rice extension in the Middle Senegal River Valley has further limited the river’s natural flooding in the floodplain (Waalo), initially reduced by drought. We conducted a transdisciplinary (TD) and gendered study in the region to explore links between agricultural biodiversity and family diets using a social analysis of women’s practices. The results showed how rice expansion impacts local agrobiodiversity, diet quality and the cultural way of life. Disappearance of the singular agropastoral and fishing system (...) of the Senegal River Valley is profoundly modifying the landscape, limiting wooded riverine settings, and is undermining the traditional diversified flood-recession cropping system in the Waalo. This is causing an overconsumption of rice by reducing alternative food sources, such as sorghum, vegetables and animal products (fish, milk and meat). In particular, flood-recession sorghums are in danger of disappearing, yet they are more nutritious than rice and now sell for twice as much, or more. The way of life is being disrupted, notably sociabilities previously based on territorial complementarities, and women are disadvantaged in terms of recognition and added workload. Women’s groups have launched collective irrigated gardens, organic or not, only supported by the local NGO, but any surplus is hardly ever sold on the weekly markets in the neighbourhood. Moreover, this diet imbalance increases nutritional risk factors for health, such as vitamin and iron deficiencies, especially for women, hypertension and diabetes. We argue that, firstly, gendered TD experiences are relevant for documenting women’s activities in order for them to gain political support and, secondly, that targeting women’s care tasks gives more value and impact to TD research results.

Farmers in Andean communities depend on complex farming systems that combine native and introduced crops, production for subsistence, and production for the market. Home to the well-known potato, the Andean region is also the native place of hundreds of lesser known varieties of tubers such as oca, ulluco, and mashua. Using data from interviews and field observation in the Peruvian community of Picol, we describe the economic and social relevance of these tuber crops in the context of the local farming (...) system. A cross-case comparison of households is used to examine the relationship between socioeconomic status and the allocation of family resources. We also explore how different agricultural practices relate to the biodiversity of indigenous tuber crops. (shrink)

This paper emerges from and aims to contribute to conversations on agricultural biodiversity loss, value, and renewal. Standard international responses to the crisis of agrobiodiversity erosion focus mostly on ex situ preservation of germplasm, with little financial and strategic support for in situ cultivation. Yet, one agrarian collective in the Peruvian Andes—the Parque de la Papa (Parque)—has repatriated a thousand native potatoes from the gene bank in Lima so as to catalyze in situ regeneration of lost agricultural biodiversity (...) in the region. Drawing on participant action research and observation, this paper engages with the projects underway at the Parque—as well as “indigenous biocultural heritage” (IBCH), the original action-framework guiding the Parque’s work. IBCH grounds the ecology of successful crop diversity within the Andean cosmovisión, or worldview—which is included, but marginalized, in mainstream agrobiodiversity conservation policies. The IBCH concept counters apolitical renderings of agrobiodiversity erosion, arguing that this disregard of biocultural heritage perpetuates colonialist devaluations of efficacious “traditional ecological knowledge” and epistemologies. Accordingly, this paper discerns here an on-site, or in situ, political ecology of agricultural biodiversity conservation. (shrink)

In the discussion about consequences of the release of genetically modified (GM) crops, the meaning of the term “environmental damage” is difficult to pin down. We discuss some established concepts and criteria for understanding and evaluating such damages. Focusing on the concepts of familiarity, biological integrity, and ecosystem health, we argue that, for the most part, these concepts are highly ambiguous. While environmental damage is mostly understood as significant adverse effects on conservation resources, these concepts may not relate directly to (...) effects on tangible natural resources but rather to parameters of land use or ecological processes (e.g., the concept of biological integrity). We stress the importance of disclosing the normative assumptions underlying damage concepts and procedures for the evaluation of damages by GM crops. A conceptualization of environmental damage should precede its operationalization. We recommend an unambiguous definition for damage developed earlier and recommend that evaluation criteria be based on this. However, a general damage definition cannot replace case-specific operationalization of damage, which remains an important future challenge. (shrink)

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 that (...) discuss the problems that arise from the application of IPR for the protection of indigenous resources highlight a salient issue: that current IPR systems may conflict and undermine the culture, social structure, and knowledge systems of indigenous societies. In order to support conservation through indigenous management of biodiversity, a number of steps are required for the negotiation of intellectual property systems that are more compatible with indigenous people's value systems and concepts of ownership.

Narratives of seed ‘loss’ and ‘persistence’ remain at loggerheads. Crop genetic diversity is rapidly eroding worldwide, we are told, and numerous studies support this claim. Other data, however, suggests an alternative storyline: far from disappearing, seed diversity persists around the world, resisting the homogenizing forces of modern capitalism. Which of these accounts is closer to the truth? As it turns out, crop biodiversity is more easily invoked than measured, more easily wielded than understood. In this essay, I (...) contend that the impasse reveals an error in the asking. We must, instead, look to the ontological, epistemic, and narrative dimensions of agrobiodiversity—and to the science, politics, and cultures of each. How is diversity empirically defined and measured? Who creates and categorizes diversity? Who does not? How is such knowledge mobilized in the accounts and narratives of different interest groups? Where, when, and why does a narrative hold true? This multi-dimensional view of agrobiodiversity makes space for a greater understanding of how diversity is created, maintained, and renewed. It suggests policy and institutional support for systems that engender such renewal of diversity, both in and ex situ. (shrink)

Biofuels have lately been indicated as a promising source of cheap and sustainable energy. In this paper we argue that some important ethical and environmental issues have also to be addressed: (1) the conflict between biofuels production and global food security, particularly in developing countries, and (2) the limits of the Human Appropriation of ecosystem services and Net Primary Productivity. We warn that large scale conversion of crops, grasslands, natural and semi-natural ecosystem, (such as the conversion of grasslands to cellulosic (...) ethanol production, or plantation of sugar cane and palm oil), may have detrimental social and ecological consequences. Social effects may concern: (1) food security, especially in developing countries, leading to an increase of the price of staple food, (2) transnational corporations and big landowners establishing larger and larger landholdings in conflict with indigenous areas and the subsistence of small farmers. Ecological effects may concern: (1) competition with grazing wild and domesticated animals (e.g., millions of grazing livestock in USA prairies), (2) an excessive appropriation of Net Primary Production from ecosystems, (3) threatening biodiversity preservation and soil fertility. We claim that is it well known how ecological and social issues are strictly interwoven and that large scale biofuels production, by putting high pressure on both fronts, may trigger dangerous feedbacks, also considering the critical fact that 9 billion people are expected to inhabit the planet by 2050. There is a need to conduct serious and deep analysis on the environmental and social impact of large scale biofuels production before important energy policies are launched at global level. Biofuels will not represent an energetic panacea and their role in the overall energy consumption will remain marginal in our present highly energivorous society, while their effect on food security and environment preservation may have detrimental results. We should also have the courage to face two key issues: (1) we cannot keep increasing resources consumption at present pace, and have to change our life style accordingly, and (2) we have to deal with population growth; we cannot expect to have 9–10 billions people inhabiting the earth by 2050, without this representing a major impact on its support system.

Rice crop diversity hasdecreased dramatically in the recent past.Understanding the causes that underlie theevident genetic erosion is critical for thefood security of subsistence rice farmers andbiodiversity. Our study shows that farmers inthe northeastern Philippines had a markedreduction in rice diversity from 1996 to 1998.The ultimate causes were a drought resultingfrom the El Niño phenomenon in 1997 andflooding due to two successive typhoons in1998. The proximate causes, however, includedlocal water control factors, limitations in thehousehold and village-level seedinfrastructure, farm location in (...) relation tothe goods and services necessary to obtainseeds, policies and programs of the Departmentof Agriculture, and the characteristics of therice varieties themselves. The implications ofour study are that genetic erosion is notalways the result of purposeful acts by farmersnor is it necessarily gradual. Improvingon-farm seed technology will stabilize the seedproduction, distribution, and use system andthereby enhance household food security.Ultimately, rice diversity will be improvedonly if diversity is a safe and viable optionfor farmers. Therefore, public policy thatsupports farmers who maintain a diverse set ofcultivars is critical for any on-farmconservation strategy. (shrink)

In a very general sense, hybrid can be understood to be any organism that is the product of two (or more) organisms where each parent belongs to a different kind. For example; the offspring from two or more parent organisms, each belonging to a separate species (or genera), is called a “hybrid”. “Hybridity” refers to the phenomenal character of being a hybrid. And “hybridization ” refers to both natural and artificial processes of generating hybrids. These processes include mechanisms of selective (...) cross-breeding and cross-fertilization of parents of different species for the purpose of producing hybrid offspring. In addition to these processes, “hybridization ” also refers to natural and artificial processes of whole genome duplication that result in the doubling or trebling of the sets of chromosomes of the organism. This entry provides an overview of the impact of hybridity on agriculture. It begins with an historical sketch that traces the early horticulturalists’ and naturalists’ investigations of hybrids. This starts with the observations of Thomas Fairchild and Georges-Louis Leclerc, Comte de Buffon; and leads to the explanation of its mechanism by Gregor Mendel, James Watson and Francis Crick, and Ernst Mayr; and the eventual manipulation of hybrids and hybridization by Barbara McClintock. Following this, the reader is introduced to a number of key terms and concepts in use within current research as well as highlighting diverse ethical concerns that center on hybridization. Recent research that attempts to ascertain the role of hybridization in adaptive change will be introduced. This will include research on the evolution of crop species, increased biodiversity, and the use of hybrids to manipulate phenotypically desirable traits in agricultural crops. The focus of the discussion is on a particularly significant type of naturally occurring hybridization, polyploidy hybridization. Polyploids are organisms which have more than two complete genomes in each cell. This kind of hybridization is ubiquitous among crop plants. The role of polyploidy in plant evolution and the affects of polyploidy on plants and animals will be reviewed. A critical discussion of its agricultural value in the production of fertile polyploid hybrids highlights key epistemological, ontological, and ethical issues. These are illuminated with reference to the distinct processes of artificial and natural hybridization. A survey of these different kinds of hybridization includes the ethical and economic impacts of hybridity on global nutrition, the environment, and considerations of some practical implications for the agricultural industry. Tracking the role of hybrids, the process of hybridization, and the current impacts of it for agriculture requires knowledge of the history of its early conceptualization, understanding, and use. This is the topic of the following section. (shrink)

Seed libraries are institutions that support the creation of semi-formal seed systems, but are often intended to address larger issues that are part of the “food movement” in the global north. Over 100 SLs are reported present in California. I describe a functional framework for studying and comparing seed systems, and use that to investigate the social and biological characteristics of California SLs in 2016 and how they are contributing to alternative seed systems based on interviews with 45 SL managers. (...) At a minimum, SLs function as new seed distribution institutions founded and overseen by dedicated, values-driven individuals and groups with goals including education, seed access, local adaptation, biodiversity conservation, community-building, and human health. Annually about 4776 people borrow seeds from, and 238 people return seeds to the SLs in this study, that operate through over 17,000 hours of work/year. These SLs distribute approximately 6456 packets of seed annually, mostly of commercial seeds from small seed companies, but some SLs emphasize local and culturally meaningful seeds. The significance of a 6% seed return rate depends on SL goals and can be investigated once appropriate indicators for those goals are identified and documented. Beyond distribution, the seed system functions accomplished by SLs differ, and all can have consequences for the processes shaping the diversity and adaptation of their crops. The SLs engaged in seed system functions beyond distribution are new forms of socially-motivated community science, poised to develop biological and social innovations reflecting their values and interests.

What is philosophically interesting about how soil is managed and categorized? This paper begins by investigating how different soil ontologies develop and change as they are used within different social communities. Analyzing empirical evidence from soil science, ethnopedology, sociology, and agricultural extension reveals that efforts to categorize soil are not limited to current scientific soil classifications but also include those based in social ontologies of soil. I examine three of these soil social ontologies: (1) local and Indigenous classifications farmers and (...) farming communities use to conceptualize their relationships with soil in their fields; (2) categorizations ascribed to farmers in virtue of their agricultural goals and economic priorities relied upon in sociological research; and (3) federal agency classifications of land capability employed by agricultural scientists. Studying the interplay of these social ontologies shows how assessing soil properties and capabilities are the result of previous agricultural strategies informed by culture, agroecological history, weather, soil biodiversity, crop rotation, and the goals held by decision-makers. The paper then identifies the soil relationships and interactions that constitute ontology-making activities. Building on recent work, I outline a novel interactive account of perspectival realism grounded in agricultural extension research and ethnopedological data that captures the haptic nature of farmers’ soil strategies. This interactive account explains how ontologies are chosen, why they are chosen, and how they interact and inform soil management decision-making. The paper concludes by examining the values laden in these ontologies and those which are causally implicated in the choice of soil management strategies. (shrink)

Oases have served as sacred landscapes and sources of ritual plants in arid regions of the Old and New Worlds. We evaluate the Jesuit mission oases of the Baja California peninsula for their role in agrobiodiversity persistence, and extend theories of sacred landscapes and biodiversity conservation to agricultural species and practices. Jesuit missionaries on the peninsula introduced a suite of crops species and agricultural and water management systems that persist in the oases and have become an integral part of (...) the cultural and religious identity of the peninsula. The sacred landscapes of the oases are defined by elements of the Jesuit mission systems, such as water capture systems and irrigation canals, stone field borders and terraces, field gardens or huertas, groves of olive trees and date palms, and multi-tiered agroecosystems. Sacred practices—including pilgrimages, religious rites, and Catholic-based community celebrations—depend on the integrated “landscapes” of the oases and on the ritual use of wild and cultivated oasis plant species. We propose that some, though not all, of the peninsula oases may be considered as sacred landscapes responsible for maintaining heritage crop species, biodiversity, and traditional farming and foodways practices.

Genebanking, the process of preserving genetic resources, is a central practice in the modern management of crop genetics, especially for the species used for food and agriculture. Closely interrelated networks of local, national and global actors are responsible for ex situ conservation. They all seek to make plant genetic resources accessible for all and now face new challenges arising from digitisation. Plant sciences are entering the postgenomic era, moving fast from initially providing a single reference genome for each species (...) (genomics), to harnessing the extent of diversity within crop species (pangenomics) and among their relatives (referred to as postgenomics). This paper describes the extent to which ex situ collections have already undergone a digital shift, or are planning to do so, and the potential impact of this postgenomic-induced dematerialisation on the global governance of plant genetic resources. In turn, digitising material (seed) collection changes the relationship between genebanks and genomic databases. Comprehensive genomic characterisation of genebank accessions is ongoing, and I argue here that these efforts may provide a unique opportunity for genebanks to further embrace the moral, ethical and ultimately political principles on which they were built. Repurposing genebanks as decentralised digital biocentres could help relocate capabilities and stewardship over genetic resources. Empowering local farmers by providing access, promoting the use and unlocking benefits from state-of-the-art tools of modern plant breeding may allow bridging the breeding divide. However, to accomplish such a paradigm shift, genebanks require a strong political mandate that must primarily originate from the access and benefit-sharing framework. Only so may the global challenges associated with the loss of biodiversity and food insecurity be addressed. (shrink)

Permaculture is primarily a thinking tool for designing low carbon, highly productive systems. It originated in Australia in the 1970s and was conceived by Bill Mollison and David Holmgren as a response to the devastating effects of a temperate European agriculture on the fragile soils of an ancient antipodean landscape. Like the dust bowls of the Great Plains in the USA in the 1930s, an alien agriculture has the capacity to turn a delicately balanced ecology into desert. Their initial response (...) was to design a permanent agriculture with tree crops and other perennials inhabiting all the niches from the canopy to the ground cover and below. The soil is left untilled to establish its own robust micro-ecology. Key to this is that the land must be biodiverse and stable for future generations. From perennial tree crops, permaculture has developed into an integrated system of design that encompasses everything from agriculture, horticulture, architecture, and ecology, as well as economy and legal systems for businesses and communities.

Meat production in South Africa is on an increasing trend. In South Africa rising wealth, urbanisation and a growing middle class means South Africans are eating more processed and high-protein foods, especially meat and dairy products. These foods are more land- and water-intensive than fruit, vegetable and grain crops, and further stress existing resources. Traditional agricultural farms cannot keep up with the increasing demand for animal products and these farms are being replaced with concentrated animal feeding operations. There are a (...) wide variety of problems caused by intensive livestock production. The concerns regarding factory farming in South Africa are social issues affecting food security, health concerns, environmental concerns and ethical concerns. In order to ensure food security in future we need to consider these concerns and support more sustainable systems to produce our food. Animal agriculture, like many other industries, works on the principles of supply and demand. By decreasing the demand for these products, we can decrease their production. Individuals can do this by becoming vegetarian or vegan, but also by simply cutting down one’s consumption of meat, eggs, and milk produced in intensive livestock farms. Less meat would be produced, and there would be less harm to local communities, lower risk of zoonotic disease outbreaks, fewer greenhouse gas emissions, less land degradation and decrease of biodiversity, less damage to our water supplies and fewer animals living lives of suffering in factory farms.

Transhumance is a form of extensive livestock production that involves seasonal movements among ecological zones or landscape types. Rangeland-based transhumance constitutes an important social and economic relationship to nature in many regions of the world, including across the Western US. However, social and ecological drivers of change are reshaping transhumant practices, and managers must adapt to increased demands for public rangeland use. Specifically, concerns for wildlife conservation have led to reduced access to seasonal public lands grazing for western US livestock (...) producers. To understand how managers adapt to loss of grazing areas (called “seasonal ranges”) we create agroecological calendars from manager records spanning 35 years (1986–2021) at the US Sheep Experiment Station in Idaho and Montana, US. The calendars illustrate how a loss of winter and summer ranges after 2013 coincided with shifts in the operation’s adaptive strategies, leading to more grazing of fall crop residue and purchased winter feed, and reducing flexibility to move livestock to cope with variable forage conditions. These changes shifted the job duties and experiences of farm workers and managers, and raised several new questions related to sheep production and vegetation management outcomes that merit future research. Transhumant system transformation has implications for human relationships with nature, rural communities, sheep genetics, production, and vegetation communities. For livestock operations that rely on government-managed lands to sustain transhumant traditions, innovative forms of collaboration and social adaptation that help secure access to seasonal ranges will be as important as technological innovations to address biodiversity conservation, climate change adaptation, and food system sustainability issues that are reshaping access to grazing lands.

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 displays a collective nature. However, it also creates partial blockages in those innovation schemes rested between on-farm observation and genetic modification, i.e. conventional plant breeding and upstream molecular biology research tools. Neither overly strong intellectual property rights, nor the absence of well delineated protection have proven an optimal fit for these two intermediary socio-technological systems of cumulative incremental innovation. To address these challenges, the authors look at appropriate institutional alternatives which can create effective incentives for in situ agrobiodiversity conservation and the equitable distribution of technologies in plant improvement, using the flexibilities of the TRIPS Agreement, the liability rules set forth in patents or plant variety rights themselves, and other ad hoc reward regimes.

In the final analysis, sustainable agriculture must derive from applied ecology, especially the principle of the regulation of the abundance and distribution of species (and, secondarily, their activities) in space and time. Interspecific competition in natural ecosystems has its counterparts in agriculture, designed to divert greater amounts of energy, nutrients, and water into crops. Whereas natural ecosystems select for a diversity of species in communities, recent agriculture has minimized diversity in favour of vulnerable monocultures. Such systems show intrinsically less stability (...) and resilience to perturbations. Some kinds of crop rotation resemble ecological succession in that one crop prepares the land for successive crop production. Such rotations enhance soil organic processes such as decomposition and material cycling, build a nutrient capital to sustain later crop growth, and reduce the intensity of pest buildup. Species in natural communities occur at discrete points along the r-K continuum of reproductive maturity. Clearing forested land for agriculture, rotational burning practices, and replacing perennial grassland communities by cereal monocultures moves the agricultural community towards the r extreme. Plant breeders select for varieties which yield at an earlier age and lower plant biomass, effectively moving a variety towards the r type. Features of more natural landscapes, such as hedgerows, may act as physical and biological adjuncts to agricultural production. They should exist as networks in agricultural lands to be most effective. Soil is of major importance in agroecosystems, and maintaining, deliberately, its vitality and resilience to agricultural perturbations is the very basis of sustainable land use. (shrink)

This paper examines classification practices in the domain of plant data semantics, and particularly methods used to label plant traits to foster the collection, management, linkage and analysis of data about crops across locations—which crucially inform research and interventions on plants and agriculture. The efforts required to share data place in sharp relief the forms of diversity characterizing the systems used to capture the biological and environmental characteristics of plant variants: particularly the biological, cultural, scientific and semantic diversity affecting the (...) identification and description of plant traits, the methods used to generate and process data, and the goals and skills of those with relevant expertise—including farmers and breeders. Through a study of the Crop Ontology (which explicitly recognizes and negotiates diversity) and its application to cassava breeding, I argue for a process-sensitive approach to the naming of plant traits that focuses on documenting environmental processes instead of biological products. I claim that this approach can foster reliable linkage and robust re-use of plant data, while at the same time facilitating dialogue between data scientists, plant researchers, breeders, and other relevant experts in ways that crucially inform agricultural interventions. I conclude that the study of data semantics and related descriptors constitutes a productive and underexplored way to think about the epistemic import of naming traits within plant science. The effort to articulate semantic differences among plant varieties and methods of data processing can generate newly inclusive ways to develop and communicate biological knowledge. In turn, such practices have the potential to defy existing understandings of systematisation and hierarchies of expertise in biology, thus bolstering the extent to which plant science can support biodiversity and sustainable agriculture.

Oases have served as sacred landscapes and sources of ritual plants in arid regions of the Old and New Worlds. We evaluate the Jesuit mission oases of the Baja California peninsula for their role in agrobiodiversity persistence, and extend theories of sacred landscapes and biodiversity conservation to agricultural species and practices. Jesuit missionaries on the peninsula introduced a suite of crops species and agricultural and water management systems that persist in the oases and have become an integral part of (...) the cultural and religious identity of the peninsula. The sacred landscapes of the oases are defined by elements of the Jesuit mission systems, such as water capture systems and irrigation canals, stone field borders and terraces, field gardens or huertas, groves of olive trees and date palms, and multi-tiered agroecosystems. Sacred practices—including pilgrimages, religious rites, and Catholic-based community celebrations—depend on the integrated “landscapes” of the oases and on the ritual use of wild and cultivated oasis plant species. We propose that some, though not all, of the peninsula oases may be considered as sacred landscapes responsible for maintaining heritage crop species, biodiversity, and traditional farming and foodways practices.

A large section of the population (70%) of Uttarakhand largely depends upon agricultural based activities for their livelihood. Rural community of the mountains has developed several indigenous and traditional methods of farming to conserve the crop diversity and rejoice agrodiversity with religious and cultural vehemence. Traditional food items are prepared during occasion, festivals, weddings, and other religious rituals from diversified agrodiversity are a mean to maintain agrodiversity in the agriculture system. Agrodiversity is an insurance against disease and extreme climatic (...) fluctuations, as a coping mechanism in times of scarcity, as a means to enhance overall productivity of farms, as a source of critical nutrition and medicine in the Himalayan region. The different traditional system of agriculture and indigenous method of maintaining soil fertility, socio-cultural and religious rituals has saved many crops that are under threatened category. But all these system and practices are ignored nauseatingly in hill agriculture policy, where more emphasis was given for plain areas. Less emphasis is being put on local systems that rely on existing natural, human, and social assets such as biodiversity, traditional knowledge, and social capital underpinning collective action to ensure food security. Of late, development planners have realized the importance of appropriate technologies and therefore have stressed the need for on-site training, and capacity building of user groups in rural areas of the region. Rural technology demonstration and training center have been supposed as a means disseminating technologies enabling improvement in the yield potential of farms, income generation from off-farm activities, and conservation and efficient use of natural resources. There is a strong need to bring desirable changes in the agricultural policy, research, and development in reference to mountainous regions. The present paper describe present scenario of agriculture, traditional, and socio-cultural practices of retaining soil fertility and agrodiversity, policy dimensions, and strategies for management of the Himalayan agroecosystems.

Immigrant farmers from Southeast Asia have brought knowledge of tropical fruit and vegetable production from their home countries to Homestead, Florida. They have developed a new style of farming, one that most closely resembles agricultural systems described as “homegardens.” Although biodiverse agricultural systems are generally thought to be commercially unviable, homegarden farmers successfully manage crop diversity as an economic strategy. By focusing on growing a mixture of specialty Southeast Asian herbs, fruits, and vegetables, the farmers have created their own (...) economic niche and have shielded themselves from the competition of high-volume, single commodity producers. This paper shows that the Homestead homegardens constitute an alternative form of agriculture that is defined by their agroecological and socioeconomic attributes. It also shows that although the homegarden farms are a form of “alternative agriculture,” they do not operate outside of conventional, global systems of agricultural trade; rather the homegarden farms are embedded in global agriculture. The Homestead case problematizes the tendency to delineate between the global and local scales, and alternative and conventional sectors in agriculture today. This paper concludes that the emergence of the Homestead homegardens can only be understood by taking a place-based approach to studying the environment in which the homegardens are situated as well as identifying the large-scale influences on Miami-Dade County.

Agriculture has long struggled to reconcile production with biodiversity conservation. Industrial farming practices that erode structural complexity within crop fields and across entire landscapes, as well as widespread pesticide use, have resulted in declining insect abundance and diversity globally. Recognition of socio-environmental consequences have spurred alternative pest management paradigms such as integrated pest management (IPM) and conservation biological control (CBC), which emphasize ecology as the scientific foundation for a sustainable agriculture. However, adoption of these approaches at scales large (...) enough to impact biodiversity has been slow, particularly in industrialized countries. Landscape-scale management is an integral component of ecological agriculture, making pest control and biodiversity conservation collective problems that require coordination among multiple stakeholders. The extent to which farmers recognize and act upon this perspective is not well studied. Through literature synthesis and a case study of Southern Wisconsin, I analyze factors shaping farmer adoption of insect and landscape management practices through the lens of constrained choice. I argue that multiple overlapping institutions (social networks, market forces, science and technology, and political-legal systems) co-produce farmer behaviors and landscape structure, largely to the detriment of ecological pest control and biodiversity. Wisconsin farmers' entomological concerns largely overlook beneficial insect species and eschew landscape thinking. Ultimately, slowing agricultural drivers of insect biodiversity declines will likely require large-scale coordination and political-economic change. (shrink)

Industrial agriculture led to a worldwide homogenization of crops and modes of cultures, but also of landscapes and relationships to the land, threatening at the same time biodiversity and cultural diversity. Developing alternatives to the agro-industrial system inherited from the twentieth century is therefore one of the greatest challenges facing humankind today. This article advocates for the promotion of the French concept of “terroir” as a foundational framework for preserving biocultural diversity, illustrating an ethical way of relating to the (...) land. Already enshrined in European law for three decades and under study at the UNESCO and the FAO, it encourages farmers to adopt ecologically virtuous practices, while ensuring greater economic incomes. Moreover, it enhances the value of their work and their specific relationship with their environment in the long run. It also epitomizes broader worldwide initiatives, which propose basing agriculture not against the environment (both human and natural) but in symbiosis with it. (shrink)

While sustainability in farming is increasingly recognised, practical implementation faces obstacles, including knowledge gaps that hinder farmers’ effective adaptation. Agricultural sensors have emerged as tools to assist farmers in offering real-time monitoring capabilities, which can provide information to support decision-making towards sustainable crop production. However, critical analyses point out that innovation in agricultural equipment predominantly focuses on optimising the dominant intensification model, while sensors might also facilitate biodiversity-based strategies toward agricultural sustainability, which aim to replace chemical inputs through (...) intensified ecological interactions. In this article, we examine the intricate relationship between technology and practice, recognising that the functionality of sensors is contingent upon the user, manner of use, and implementation context. We employ social practice theory to examine farmers’ current sensor usage and broader sensing practices in farming system strategies that align either more with efficiency/substitution-based or with biodiversity-based approaches toward agricultural sustainability. Through this approach, we elucidate how sensors and sensing practices contribute to knowledge production and management in both farming systems. Drawing on 11 semi-structured interviews with Dutch farmers, we identify diverse sensing practices that can enable different types of knowledge: oversight—enabling farmers to optimise the efficiency of production—and insight—offering a holistic and long-term understanding of ecological relations and how they affect production. We conclude by discussing the implications of these sensing practices and types of knowledge for strategies for agricultural sustainability. (shrink)

Through a discursive and organizational analysis we seek to understand the Biosafety Protocol and the place of socioeconomic regulation of agricultural biotechnology in it. The literature on the Protocol has been fairly extensive, but little of it has explored debates over socioeconomic regulation during the negotiation process or the regulatory requirements specified in the final document. This case is especially important at a time when the spread of neoliberalism is increasingly associated with deregulation, because it sheds light on the conditions (...) under which circumvention of the market is deemed legitimate and socio-economic regulation of agricultural technology is possible.

This book explores the epistemological and ethical issues at the foundations of environmental philosophy, emphasising the conservation of biodiversity. Sahota Sarkar criticises attempts to attribute intrinsic value to nature and defends an anthropocentric position on biodiversity conservation based on an untraditional concept of transformative value. Unlike other studies in the field of environmental philosophy, this book is as much concerned with epistemological issues as with environmental ethics. It covers a broad range of topics, including problems of explanation and (...) prediction in traditional ecology and how individual-based models and Geographic Information Systems technology is transforming ecology. Introducing a brief history of conservation biology, Sarkar analyses the consensus framework for conservation planning through adaptive management. He concludes with a discussion of directions for theoretical research in conservation biology and environmental philosophy. (shrink)

Advances in biotechnology mean that it may soon be possible to recreate previously extinct species. This has led to an emerging debate within bioethics about whether we ought to reintroduce extinct species into our ecosystems. In this paper, we discuss the role that biodiversity could play in this debate. Many believe that biodiversity is a good that should be protected. We argue that if biodiversity is a good, then this suggests it should also be promoted, including by (...) reintroducing previously extinct species. We begin by outlining different ways in which biodiversity could be conceptualized, and then analyze various accounts of its value. We suggest no approach justifies an asymmetry between “protecting” biodiversity by conserving species alive today, and “creating” biodiversity by introducing previously extinct species. This suggests that if we have reasons stemming from biodiversity to protect species from extinction, we will have similar reasons to reintroduce previously extinct species. We close by asking whether arguments from biodiversity speak in favor of introducing some novel species into the ecosystem. (shrink)

This essay argues that we have a duty to protect biodiversity hotspots, rooted in an argument about the wrongful imposition of risk and intergenerational justice. State authority over territory and resources is not unlimited; the state has a duty to protect these areas. The essay argues that although biodiversity loss is a global problem, it can be tackled at the domestic level through clear rules. The argument thus challenges the usual view of state sovereignty, which holds that authority (...) over territory, resources, and migration (all of which are connected to the protection of biodiversity hotspots) is unlimited.

After wondering why environmental aestheticians tend to undervalue biodiversity as an indicator of nature’s well-being, I discovered that Philosophy and Science are in a face off regarding biodiversity’s utility. For the most part, philosophers meet science’s confidence regarding biodiversity with skepticism. Rather than get bogged down in technical disagreements between scientists and philosophers over the possibility of measuring and utilizing biodiversity, this paper sidesteps that conflict by turning to the relationship between biodiversity and cultural engagement. (...) By describing: the link between spoken languages and species diversity, the significance of cultural differences, the role of cities and remote communities in encouraging and safeguarding biodiverse habitats, and the heterogeneous nature of difference itself when determining biodiversity; I effectively demonstrate how human beings who value their own culture protect nature, which reveals the most important reason to value biodiversity. Biodiversity may be impossible to track, extremely difficult to measure, and shares no correlation with stability, yet no other yardstick indicates cultural proliferation. This paper surveys three ways in which biodiversity can serve as a bio-indicator for human cultural engagement, just as lichens are bio-indicators for air pollution, ozone depletion, and metal contamination.

The biodiversity crisis should be a key issue within debates on global justice – but to date it has not been. This article aims to provide a stimulus to further engagement. First, it provides a brief introduction to the notion of a biodiversity crisis, and to its origins. Second, it distinguishes our various reasons for caring about the crisis. Third, it shows why the biodiversity crisis raises important – albeit hitherto neglected – issues of global justice. Fourth, (...) it sketches some of the most important questions scholars of global justice should be in a position to engage with, in order to move the debate forwards and help ensure that collective political responses to the crisis are just ones.

Biodiversity conservation as a practical discipline has been significantly transformed over the past twenty years. Given the extent to which humans influence not only biodiversity loss, but also geographical distribution, and ecological dynamics, there has been a shift in the study of conservation as a scientific discipline from a concern strictly with ecological and biological diversity measures to an interdisciplinary field, drawing upon the human sciences. We draw upon several case studies to argue for the importance of attention (...) to local stakeholders, culture, and community values, in conservation practice. (shrink)

Biodiversity has become one of the most important conservation values that drive our ecological management and directly inform our environmental policy. This paper highlights the dangers of strategically appropriating concepts from ecological sciences and also of uncritically inserting them into conservation debates as unqualified normative landmarks. Here, I marshal evidence from a cutting-edge research program in microbial ecology, which shows that if species richness is our major normative target, then we are faced with extraordinary ethical implications. This example challenges (...) our well-received beliefs about biodiversity and it invites us to critically rethink the nature of this concept so that a more robust understanding of biodiversity and of its role in conservation policy could emerge.
