For many activists and scholars, urban agriculture in the Global North has become synonymous with sustainable food systems, standing in opposition to the dominant industrial agri-food system. At the same time, critical social scientists increasingly argue that urban agriculture programmes, by filling the void left by the “rolling back” of the social safety net, underwrite neoliberalisation. I argue that such contradictions are central to urban agriculture. Drawing on existing literature and fieldwork in Oakland, CA, I explain how urban agriculture arises from a protective counter-movement, while at the same time entrenching the neoliberal organisation of contemporary urban political economies through its entanglement with multiple processes of neoliberalisation. By focusing on one function or the other, however, rather than understanding such contradictions as internal and inherent, we risk undermining urban agriculture's transformative potential. Coming to terms with its internal contradictions can help activists, policy-makers and practitioners better position urban agriculture within coordinated efforts for structural change, one of many means to an end rather than an end unto itself.  相似文献

The development of the aquaculture industry in Canada has triggered a conflict of a scope never seen before. As stated in Young and Matthews’ The Aquaculture Controversy, this debate has “mushroomed over the past several decades to become one of the most bitter and stubborn face-offs over industrial development ever witnessed in Canada” (Young and Matthews in The aquaculture controversy in Canada. Activism, policy and contested science. UBC Press, Vancouver, p 3, 2010). It opposes a wide variety of actors: from industrial investors, scientists, politicians and environmentalists to Native associations and communities, citizens groups and local stakeholders. The opposition is fierce between those in favor of a flourishing and modern aquaculture of industrial nature and those who fear the dreadful consequences of such an industry. In particular, the possible implementation of biotechnology innovations, such as a genetically modified salmon, has made this debate coextensive with the GMO debate, thus multiplying the opposition’s spectrum of arguments against the industry. Throughout the debate, Canadian environmental NGOs like the Suzuki Foundation and Greenpeace Canada have assumed leadership over the opposition to aquaculture development with certain success. Their participation in the debate features numerous ethical concerns related to environmental health, a respect for wilderness and local human communities. Such a position can be associated overall with a form of ecocentric ethics or concern. Nevertheless, a careful examination of the technical solutions proposed by these NGOs reveals their embeddedness in biocentrism. Through the example taken from the Canadian debate on aquaculture development, this paper aims to highlight the conceptual difficulty of enacting ecocentric ethical positions beyond formal arguments. Because ecocentrism implies a true paradigm shift, not only in mentality, but also in the way we conceive our technical interventions in nature, biocentrism remains an important practical method to enact ethical positions related to environmental concerns in public debates.  相似文献

A plethora of ethical issues in livestock agriculture has emerged to public attention in recent decades, of which environmental and animal welfare concerns are but two, albeit prominent, themes. For livestock agriculture to be considered sustainable, somehow these interconnected themes need to be addressed. Ethical debate on these issues has been extensive, but mostly started from and focused on single issues. The views of farmers in these debates have been largely absent, or merely figured as interests, instead of being considered morally worthwhile themselves. In this paper the relevance for ethical debates of the ways farmers discuss and engage with moral concerns is explored. The variety of norms that figure in contemporary farming practices is sketched in its multifarious complexity, illustrated by ethnographic fieldwork, and systematized in terms of “orders of worth.” Reviewing the practical arguments and commitments of farmers within this framework reveals that farming practices are subject to mixed motives, in which an amalgam of types of concerns play a role. Recognition of the peculiarly entangled nature of the ethics of farming practices could counter the tendency in policy making, technological innovation, and ethical thought to compartmentalize our moral landscape. Understanding farming practice as the integration of a mosaic of concerns in the light of a variety of moral experiences would foster public appreciation of positions of farmers in debates on improving the sustainability and societal acceptability of livestock agriculture.  相似文献

The challenge of pursuing sustainability in agriculture is often viewed as mainly or wholly technical in nature, requiring the reform of farming methods and the development and adoption of alternative technologies. Likewise, the purpose of sustainability is frequently cast in utilitarian terms, as a means of protecting a valuable resource (i.e., soil) and of satisfying market demands for healthy, tasty food. Paul B. Thompson has argued that the embrace of these views by many in the consumer/environmental movement enables easy co-optation by agribusiness. It also reflects a critical weakness in this movement: a lack of commitment to philosophical principles that depart from the utilitarian premises of the industrial model of agriculture. This paper draws on the writings of Thomas Berry and Liberty Hyde Bailey to identify the philosophical principles of what we call planetary agrarianism. From the perspective of planetary agrarianism, the pursuit of sustainability is a broad and challenging moral, educational, and political task. Berry helps us see that it is fundamentally a project of worldview transition, which requires a new cultural narrative that must rival, in form and appeal, the mythic power of the utilitarian industrial vision. Liberty Hyde Bailey, author of The Holy Earth (1915) and a leader in the land-grant education and nature-study movements, took up the project of worldview transition in his life work. While in some ways dated and flawed, Bailey’s writings are a valuable source of guidance for developing and pursuing a viable philosophy of agriculture for the 21st century.  相似文献

One common method of criticizing genetically modified organisms (GMOs) is to label them as “magic bullets.” However, this criticism, like many in the debate over GMOs, is not very clear. What exactly is the “magic bullet criticism”? What are its origins? What flaw is it pointing out in GM crops and agricultural biotechnology? What is the scope of the criticism? Does it apply to all GMOs, or just some? Does it point to a fatal flaw, or something that can be fixed? The goal of this paper is to answer these questions and clarify the magic bullet criticism of agricultural biotechnology. It is hoped that the results of this exercise will be helpful in advancing deliberation over the role GMOs and agricultural biotechnology should play in 21st century agriculture.  相似文献

Industrial (“white”) biotechnology promises to contribute to a more sustainable future. Compared to current production processes, cases have been identified where industrial biotechnology can decrease the amount of energy and raw materials used to make products and also reduce the amount of emissions and waste produced during production. However, switching from products based on chemical production processes and fossil fuels towards “biobased” products is at present not necessarily economically viable. This is especially true for bulk products, for example ethanol production from biomass. Therefore, scientists are also turning to genetic modification as a means to develop organisms that can produce at lower costs. These include not only micro-organisms, but also organisms used in agriculture for food and feed.The use of genetic modification for “deliberate release” purposes, in particular, has met great opposition in Europe. Many industrial biotechnology applications may, due to their scale, entail deliberate releases of GM organisms. Thus, the biobased economy brings back a familiar question; is it ethically justifiable, and acceptable to citizens, to expose the environment and society to the risks associated with GM, in order to protect that same environment and to sustain our affluent way of life? For a successful innovation towards a biobased economy, its proponents, especially producers, need to take into account (take responsibility for) such issues when developing new products and processes. These issues, and how scientists can interact with citizens about them in a timely way, are further explored in projects at Delft University and Leiden University, also in collaboration with Utrecht University.  相似文献

The concepts of sustainable agriculture, organic agriculture, regenerative agriculture, and alternative agriculture are receiving increasing attention in the academic and popular literature on present trends and future directions of agriculture. Whatever the reasons for this interest, there nevertheless remain differences of opinion concerning what counts as a sustainable agriculture. One of the reasons for these differences is that the moral underpinnings of a policy of sustainability are not clear. By understanding the moral obligatoriness of sustainability, we can come to understand precisely what must be sustained, and by implication, how. This article discusses the arguments that can be advanced for sustaining anything and initially concludes that our obligations to future generations entail sustaining more than just sufficient food production or an adequate resource base. Indeed, a tradition of care and community must underlie whatever agricultural and resource strategies we are to develop under the rubric of sustainability. A consideration of the larger social and environmental system in which agriculture operates and the constraints this system places on agriculture forces us to recognize that sustainability has to do with larger institutional issues, including our ability to incorporate our common morality democratically into our institutions, practices, and technologies.  相似文献

The promising spread of sustainable agriculture in Asia   总被引:1,自引:0,他引:1  
Despite great successes in increasing food production, Asia still faces enormous food security challenges. Most commentators agree that there will have to be increases in food production from existing agricultural land, but many are pessimistic about the future, judging likelihood of success on the basis of past performance of 'modern' agricultural development. Sustainable agriculture, though, offers entirely new opportunities, by emphasising the productive values of natural, social and human capital, all assets that Asian countries either have in abundance or that can be regenerated at relatively low financial cost.
This paper sets out an assets-based model of agricultural systems, together with a typology of eight approaches for sustainable agriculture improvements. In the 16 projects/initiatives spread across eight countries that are analysed, some 2.86 million households have substantially improved total food production on 4.93 million hectares, resulting in greatly improved household food security. Proportional yield increases are greatest in rainfed systems, but irrigated systems have seen small cereal yield increases combined with added production from additional productive system components (such as fish in rice, vegetables on dykes). The additional positive impacts on natural, social and human capital are also helping to build the assets base so as to sustain these improvements in the future.
This analysis indicates that sustainable agriculture can deliver large increases in food production in Asia. But spreading these to much larger numbers of farm households will not be easy. It will require fundamental policy reform.  相似文献

Social licence and mining: A critical perspective   总被引:1,自引:0,他引:1  
In 2002 the International Institute of Environment and Development published the landmark report Breaking New Ground: Mining, Minerals and Sustainable Development (MMSD). The report portrayed an industry distrusted by stakeholders and under threat from opposition groups. When read closely, the MMSD report reveals an inextricable link between industry's ‘survival’ instincts and the notion of a social licence. Within the context of a growing divergence around the expectations of minerals-led development, social licence has emerged as an industry response to opposition and a mechanism to ensure the viability of the sector. The objective of this article is to reinvigorate discussion and debate over how best to frame the industry's social and environmental obligations and how these obligations can be met by the sector. Where social licence has contributed to raising the profile of social issues within a predominantly industrial discourse, a primary failure is its inability to articulate a collaborative developmental agenda for the sector or a pathway forward in restoring the lost confidence of impacted communities, stakeholders, and pressure groups. We argue that a necessary first step in this process is for industry to reconcile its internal risk-orientation with external expectations which requires a less defensive and more constructive approach to stakeholder engagement and collaboration.  相似文献

The British pride themselves on their long tradition of landscape management rooted in the aristocratic and landowning classes of the 18th and 19th centuries. The British also emphasize that the rise of modern pollution control began in the Victorian industrial era with the emergence of the national Inspectorates and the local Commissioners of Sewers. All these traditions are rooted in British social history, which was heavily influenced by class, power, and the changing shape of industrial and agricultural development. In modern Britain, affected by industrial recession, where concern over jobs and growth appears to dominate public and political attention, as well as public spending cuts that sap the morale and effectiveness of the major regulatory agencies, attitudes toward, and the execution of, environmental protection are undergoing a subtle but profound revolution. It is slowly but agonizingly being recognized that economic growth and social well-being cannot be disconnected from environmental processes and the limits these impose on management and technological intervention. A 21st century Britain will have to integrate conservation with development in order to survive.  相似文献

This paper spells out and discusses four assumptions of the deficit model type of thinking. The assumptions are: First, the public is ignorant of science. Second, the public has negative attitudes towards (specific instances of) science and technology. Third, ignorance is at the root of these negative attitudes. Fourth, the public’s knowledge deficit can be remedied by one-way science communication from scientists to citizens. It is argued that there is nothing wrong with ignorance-based explanations per se. Ignorance accounts at least partially for many cases of opposition to specific instances of science and technology. Furthermore, more attention needs to be paid to the issue of relevance. In regard to the evaluation of a scientific experiment, a technology, or a product, the question is not only “who knows best?,” but also “what knowledge is relevant and to what extent?.” Examples are drawn primarily from the debate on genetic engineering in agriculture.  相似文献

FAO has a unique and essential rolein addressing the ethical problems facinghumanity and in making these problems intoopportunities for practical resolution. A broadrange of ethical issues in agriculture,fisheries, and forestry were identified byanalysis of the literature and by interviewswith FAO staff. Issues include sharing accessto and preserving natural resources,introduction of new technology, conservatismover the use of genetic engineering, ethics inanimal agriculture, access to information, foodsecurity, sustainable rural development,ensuring participation of all people indecision making and in receiving benefits ofagriculture, reducing corruption, andinvolvement of private and public sectors indecision making. Rather than viewing theseissues as problems, they should be viewed asopportunities for debate, learning aboutothers' views, and resolution. The UnitedNations has an important role to play in howdecisions are made in the global ethical debatein food and agriculture. The ethical role ofFAO is to promote global food security,balanced conservation, management andutilization of natural resources, andsustainable rural development. FAO should fullyand publicly assume its ethicalresponsibilities, gathering and sharinginformation on ethics in its areas of mandate,acting as an interactive forum, and providingexpert guidance on policy options and choicesbased on practical ethical analysis.  相似文献

ABSTRACT: This paper reports on new methods of linking climate change scenarios with hydrologic, agricultural an water planning models to study future water availability for agriculture, an essential element of sustainability. The study is based on the integration of models of water supply and demand, and of crop growth and irrigation management. Consistent modeling assumptions, available databases, and scenario simulations are used to capture a range of possible future conditions. The linked models include WATBAL for water supply; CERES, SOYGRO, and CROPWAT for crop and irrigation modeling; and WEAP for water demand forecasting, planning and evaluation. These models are applied to the U.S. Cornbelt using forecasts of climate change, agricultural production, population and GDP growth. Results suggest that, at least in the near term, the relative abundance of water for agriculture can be maintained under climate change conditions. However, increased water demands from urban growth, increases in reservoir evaporation and increases in crop consumptive use must be accommodated by timely improvements in crop, irrigation and drainage technology, water management, and institutions. These improvements are likely to require substantial resources and expertise. In the highly irrigated basins of the region, irrigation demand greatly exceeds industrial and municipal demands. When improvements in irrigation efficiency are tested, these basins respond by reducing demand and lessening environmental stress with an improvement in system reliability, effects particularly evident under a high technology scenario. Rain-fed lands in the Cornbelt are not forced to invest in irrigation, but there is some concern about increased water-logging during the spring and consequent required increased investment in agricultural drainage. One major water region in the Cornbelt also provides a useful caveat: change will not necessarily be continuous and monotonic. Under one GCM scenario for the 2010s, the region shows a significant decrease in system reliability, while the scenario for the 2020s shows an increase.  相似文献

ABSTRACT: In southern Alberta, as elsewhere, pressures on limited water supplies are increasing. Not surprisingly, a great deal of attention has been focused on irrigated agriculture, which accounts for the largest share of water consumed in the region. In order to meet broadly accepted water conservation goals, some commentators have suggested that irrigation water use should be metered and that irrigators should be charged based on the amount of water used. An alternative proposal would have water management authorities rely upon the perceived adaptability of irrigators. This paper offers a perspective on the willingness of irrigators to conserve water. Based on a survey of 183 irrigation farmers conducted over the summer and early fall of 1998, we found that irrigators are generally aware of the need to conserve water and soil moisture, and that a variety of water conserving strategies were being employed. Water saving technologies specific to irrigation agriculture were less widely adopted. The findings suggest that there is considerable potential to reduce the amount of water consumed by the irrigation sector through increased efficiency, but that change will be limited if current economic circumstances and institutional arrangements persist.  相似文献

The characteristics and role of the family farm have profoundly influenced the quality of human ecology. Considerable debate exists about the role of the family farm in the United States. This article attempts to clarify aspects of this debate by: (a) examining various definitions of the family farm and the conclusions that flow from these definitions, (b) presenting results of a structural analysis of American agriculture to better understand the origins of the debate and the relationship between people and agriculture, and (c) discussing the relevancy of some data and concepts used in evaluating the consequences of the structure of the agricultural sector.  相似文献

World water dynamics: global modeling of water resources   总被引:19,自引:0,他引:19  
The growing scarcity of fresh and clean water is among the most important issues facing civilization in the 21st century. Despite the growing attention to a chronic, pernicious crisis in world's water resources our ability to correctly assess and predict global water availability, use and balance is still quite limited. An attempt is documented here in modeling global world water resources using system dynamics approach. Water resources sector (quantity and quality) is integrated with five sectors that drive industrial growth: population; agriculture; economy; nonrenewable resources; and persistent pollution. WorldWater model is developed on the basis of the last version of World3 model. Simulations of world water dynamics with WorldWater indicate that there is a strong relationship between the world water resources and future industrial growth of the world. It is also shown that the water pollution is the most important future water issue on the global level.  相似文献
