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

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

Public policy on the development and use of genetically modified organisms (GMOs) has mainly been concerned with defining proper strategies of risk management. However, surveys and focus group interviews show that although lay people are concerned with risks, they also emphasize that genetic modification is ethically questionable in itself. Many people feel that this technology “tampers with nature” in an unacceptable manner. This is often identified as an objection to the crossing of species borders in producing transgenic organisms. Most scientists reject these opinions as based on insufficient knowledge about biotechnology, the concept of species, and nature in general. Some recent projects of genetic modification aim to accommodate the above mentioned concerns by altering the expression of endogenous genes rather than introducing genes from other species. There can be good scientific reasons for this approach, in addition to strategic reasons related to greater public acceptability. But are there also moral reasons for choosing intragenic rather than transgenic modification? I suggest three interrelated moral reasons for giving priority to intragenic modification. First, we should respect the opinions of lay people even when their view is contrary to scientific consensus; they express an alternative world-view, not scientific ignorance. Second, staying within species borders by strengthening endogenous traits reduces the risks and scientific uncertainty. Third, we should show respect for nature as a complex system of laws and interconnections that we cannot fully control. The main moral reason for intragenic modification, in our view, is the need to respect the “otherness” of nature.  相似文献

This paper is the result of a contribution between ethics and law, which will be used as thought-process tools, to address the complex issue of legal and ethical statuses of GM fish. To find answers, we propose to consider this issue from a wider angle, looking at the relations between the human, animal, and living worlds. We show that it is possible to construct other forms of intellectual logic that, without setting these worlds in opposition, do not lapse into relativism where boundaries are blurred. In this sense, we submit the hypothesis that ordered pluralism should help us to move past a mere Man–Animal relationship to reveal the entire complexity of relationships within mankind and between mankind and other (non-human) worlds alongside it and to which it belongs: the animal and living worlds. With this new logic, “animal ethics” and “animal law” are re-embedded into a set of relationships. This logic emerges from a new consideration: the nature of the contemporary objects we are dealing with. We shall call objects like genetically modified fish “relational objects” in the sense that in order to be apprehended, they utilize a set of relationships of which there are just as many as the dimensions forming them, not as predicates but as primary constituents. Experimentally, in the case of GM fish, we translate this by proposing to typologize legal and ethical considerations induced by multiple relations connected to this object. According to the type of relationship in question, the GM fish will not have the same status; it is a changing object that must be suitably apprehended.  相似文献

Concern for what we do to plants is pivotal for the field of environmental ethics but has scarcely been voiced. This paper examines how plant ethics first emerged from the development of plant science and yet also hit theoretical barriers in that domain. It elaborates on a case study prompted by a legal article on “the dignity of creatures” in the Swiss Constitution. Interestingly, the issue of plant dignity was interpreted as a personification or rather an “animalization of plants.” This sense of irony makes sense when one realizes that on scientific grounds the plant is a “second animal,” i.e., it differs from the animal in degree of life or some ethically-relevant criterion but not in nature. From the point of view of ethics however, plants should be defended for what they are by nature and not by comparison to external references: the ethical standing of plants cannot be indexed to animals. It is thus reckoned that to circumvent this odd fetishism, the plant ethics can only be adequately addressed by changing the theory of plant science. Common sense tells us this: plants and animals belong to radically different fields of perception and experience, a difference that is commonly captured by the notion of kingdom. In this paper we remind the ethical conversation that plants are actually incommensurable with animals because they are unsplit beings (having neither inside nor outside), i.e., they live as “non-topos” in an undivided, unlimited, non-centered state of being. It is concluded that the unique ontology of plants can only be addressed through a major change from object-thinking to process-thinking and a move from ego-centric to “peri-ego” ethics.  相似文献

This paper argues that in modern (agro)biotechnology, (un)naturalness as an argument contributed to a stalemate in public debate about innovative technologies. Naturalness in this is often placed opposite to human disruption. It also often serves as a label that shapes moral acceptance or rejection of agricultural innovative technologies. The cause of this lies in the use of nature as a closed, static reference to naturalness, while in fact “nature” is an open and dynamic concept with many different meanings. We propose an approach for a dynamic framework that permits an integrative use of naturalness in debate, by connecting three sorts of meaning that return regularly in the arguments brought forward in debate; cultural, technological, and ecological. We present these as aspects of nature that are always present in the argument of naturalness. The approach proposes a dynamic relation between these aspects, formed by gradients of naturalness, which in turn are related to ethical concerns. In this way we come to an overview that makes it possible to give individual arguments a relative place and that does justice to the temporality of the concept of nature and the underlying ethical concerns stakeholders have in respect to innovation in agriculture.  相似文献

This article is a conceptual contribution on how to make human habitat more sustainable. Taking Heidegger’s conception of “dwelling” as a starting point, a new form of understanding the organization of the city as a human habitat is proposed. It is argued that human habitat is today in crisis and that such crisis has its roots in a spatial understanding of human dwelling, disregarding its temporal-historical dimension. For long time, the city has been considered as a physical “place” and its organization—the urban planning—has been addressed in terms of “locating” (building). Many of the challenges in organizing habitat are the result of reducing the organization of the city to the organization of physical space. One of these is the conflict between preservation and development, a central issue in approaching sustainability. The aim of this article is to propose a new perspective on the organization of human dwelling, which overcomes the spatial-based conception of habitat and involves its temporal dimension. The meaning of human “habitat” as a historical process for developing “habits” will be recovered, and the implications for organization of the city considered. Human habitat is above all an ethical space (ethos), constituted in a spatial–temporal process of developing learning and capabilities. This habitat can be shared and developed infinitely so that a pathway is opened for overcoming the logic of competition and the conflict between sustainability and development. Finally, three forms of the human habitat as an “ethical space” are proposed.  相似文献

This paper analyses how discourses of “new nature” have been implemented in the Dutch context – as a front runner of broader “rewilding” processes throughout Europe – frequently tied to imperatives of water safety. Drawing on the specific case of the Millingerwaard, we first examine how such discourses have materially, as well as socially, transformed the landscape in question. The paper then explores how these transformations have erstwhile affected those living in the area – in ways that are perceived, positively or negatively – according to varied groups of residents and users. In doing so, we critically reflect not only on “new nature” as it has been conceived within planning processes, and empirically practiced, in the Netherlands, but also how it is described and experienced by those whose lives are intimately tied to the landscape.  相似文献

This paper reviews analytical procedures for deducing from annual streamflow data information required for water resources systems planning. The procedure relies on two techniques to determine the extent that cycles exist in annual time series data. The first is to observe how the time series behaves around the mean annual flow. If it tends not to move across the mean frequently, it is concluded that a cyclical nature exists. The second technique is to observe the time path of accumulated departures from the mean annual flow. The validity of both techniques is questioned. The first because it uses mean flow as “normal” or the flow that the time series should fluctuate around. The second because the accumulated departure from the mean time series will be autocor-related even when the individual annual or seasonal flow observations are uncorrected. Alternative analytical techniques, which find no cycles, are presented.  相似文献

ABSTRACT: Watershed stewardship activities throughout North America have evolved into a process that requires more involvement in planning and decision making by community stakeholders. Active involvement of all stakeholders in the process of watershed stewardship is dependent on effective exchange of information among participants, and active involvement of a wide range of stakeholders from “communities of place” as well as those from “communities of interest.” We developed a map‐based stream narrative tool as a means to: (a) assemble a wealth of incompletely documented, “traditional” ecological or natural history observations for rivers or streams; and (b) promote a higher level of active involvement by community stakeholders in contributing to information‐based, watershed management. Creation of stream narratives is intended for use as a tool to actively engage local stakeholders in the development of a more comprehensive information system to improve management for multiple stewardship objectives in watersheds. Completion of map‐based stream narrative atlases provides a valuable supplement to other independent efforts to assemble observations and knowledge about land‐based natural resources covering entire watersheds. We are confident that completion of stream narrative projects will make a valuable addition to the information and decision making tools that are currently available to the public and resource agencies interested in advancing the cause of community‐based approaches to watershed and ecosystem management.  相似文献

Along with the increasing number of automotive output and End-of-Life vehicles (ELVs) in China, resources shortage and environmental pollution are aggravating, so the tremendous need to reuse automotive components gives birth to the industry. The Chinese government becomes to realize that it is necessary to build a conservation-oriented and environment-friendly harmonious society. As the ultimate form of recycling, remanufacturing will be an effective method to promote the development of Chinese circular economy. The automotive remanufacturing industry in China is just at the preliminary stage, this paper presents some problems before remanufacturing, during remanufacturing and after remanufacturing, and then it points out several barriers, such as restrictive policies and regulations, consumer acceptance, scarcity of technologies, etc. Like many other developed countries, Chinese remanufacturing industry will also experience the primary stage, growth stage and developed stage. while the emphasis of resources input will not be the same. By analyzing the resources input characteristics at different development stages, three development patterns, such as the Government Incenting Pattern, Technology Driving Pattern and Market Leading Pattern, are put forward. At present, the cooperation of the government, industry, universities and research institutes, etc, will jointly construct the enhancing system of automotive components remanufacturing industry in China. Finally, it concludes with a summary and some suggestions in the field.  相似文献

The Scottish Government is committed to carbon reduction targets which are the most ambitious across the devolved administrations of the UK. Whilst Scotland operates within broader international and UK policy contexts, it has developed particular programmes and approaches to engage communities in the transition towards low-carbon futures. Rural areas have a role in the transition to a low-carbon Scotland; however, beyond land use and agriculture contributions, little research has explored the “rural” dimension of “low-carbon” transitions. The paper presents a policy and literature review relating to the low-carbon agenda in Scotland. It reflects on Scottish low-carbon policy and governance, the positioning of “rural communities” within this, and the opportunities and challenges this might present. Based on this, we develop an understanding of how rural communities may contribute to a low-carbon Scotland and identify a future research agenda to explore in more detail the nature and relative effectiveness of diverse governance structures to support this.  相似文献

ABSTRACT: The agricultural revolution occurred because the un-managed environment was not providing food in either the quantity or quality that society desired. The “environmental revolution” is developing because the unmanaged environment is clearly not capable of assimilating societal wastes without being seriously degraded. Effective environmental management will require regional and site-specific modification of general principles and practices that can be used at a national or international level. An environmental management system can be operated in the same manner as any industrial quality control system with three basic components: (a) sensors at appropriate locations, (b) rapid generation and feedback of information, and (c) a quality control group capable of taking immediate effective action when system performance is outside predetermined boundary conditions. This discussion focuses primarily on three areas: (a) management options available to regulate intrusion of societal wastes into natural systems, (b) types of methods available for predicting and validating effects on natural systems, and (c) modifications of present legislation that would permit the most flexibility in selecting from the various management options. Also considered are multispecies toxicity tests using species with cosmopolitan distribution in test systems with a high degree of environmental realism. Among the many values of such tests is the ability to exchange information from all parts of the world effectively because the test organisms are not restricted to a particular geographic region.  相似文献

ABSTRACT In water planning activities, major emphasis has been placed on the development of procedures for devising “optimum plans.” These plans are defined as those which meet prespecified demands for water at “minimum cost.” However, all plans are developed subject to postulated conditions regarding the state of the physical system and of nature. Because planning takes place in a dynamic and uncertain environment in which postulated conditions are known to change, it is imperative that the planner be apprised in the planning phase of the effect of changes which can occur. Using “this information, a planner can temper his judgment with a knowledge of the effect of the uncertainty resulting from changes in the system state variables. This paper presents results of the use of a computer simulation and optimization model to quantify possible variations in system response which could occur as a result of uncertainty in the postulated physical and economic conditions under which the proposed water development system was to perform. The possible effects of these variable responses on planning decision-making is discussed.  相似文献

The present physiognomy of the surface of planet Earth is the outcome of interactions between three systems: nature, humans and technologies. Each evolved throughout history. Nature (including the climate) has its history on the scale of millions of years. Humans and their societal organization (the sociosphere) have their history on the scale of thousands of years. Technologies, their applications and their structural manifestations (the technosphere), are products of human ingenuity and have their history, associated with the industrial revolution, on the scale or hundreds of years. The scales of history are different and the factors that control the processes operative in each of the three systems are different. However, the events that make the contemporary scene and the forces that shape the transformations of tomorrow relate to the complex interactions between these three systems. The differences entail the inherent difficulties of these interactions, and as humans are the principal operators of these interactions, human failures often add to these difficulties and result in what have become recognized as environmental problems.  相似文献

The Japanese are traditionally regarded as nature-loving people, living in “harmony” with nature. However, this assumption is difficult to accept when observing the environmental problems in Japan. How can one explain the incongruities? Has the Japanese people's attitude toward nature changed as Japan has modernized? Is the concept of the nature-loving Japanese merely a myth? Is there another reason to explain this contradiction? This study shows political and economic origins of the paradox. The origin of the Japanese traditional idea of nature is fear and reverence of nature based on a primitive religion that developed in a rural subsistence living situation. Aesthetic and spiritual values of nature for cultural, educational, and intellectual entertainment were developed by the ruling class in the seventh century. Japan's first nature conservation movement, imported from the West, developed among the intellectual community and was advocated and promoted by the elite in the Meiji period (1868–1911). However, because deep commitment was lacking, the movement was abused by the military government before World War II. In the early 1970s the nature conservation movement seemed to be on the ascendancy, mainly because it was combined with the antipollution movement claiming the basic rights of survival. The Japanese nature conservation movement is still in the embryonic stage; in the future, the blending of some traditional resource management with the scientific philosophy of nature conservation may help promote the new wave of nature conservation in Japan.  相似文献

This paper presents a fuzzy logic-based tool for assessing the pollution concentration of effluents generated by various industrial and commercial activities. The study proposes a fuzzy overall pollution compliance index (FOPCI) (range 0–100) to classify the wastewater discharged from various types of properties present in Ajman, United Arab Emirates. The work mainly focused on three types of pollution that can occur at the inlets of the wastewater treatment plant of Ajman, due to discharge of industrial and commercial effluents, namely pH pollution, salt pollution, and organic pollution. The proposed FOPCI integrates six characteristics, namely pH, Cl?, SO4 2?, conductivity, chemical oxygen demand (COD), and fats, oils, and greases (FOG) values into a readily understandable scale. The FOPCI is developed by using the Fuzzy Inference System Toolbox available in MATLAB in two steps, in which during the first step, three sub-indices, namely fuzzy pH compliance index, fuzzy salt compliance index, and fuzzy organic compliance index are developed. It is then processed in the second stage to develop the FOPCI. Fuzzy rules are used to classify effluents quality into six categories based on the concentration of pollutant in the effluent, namely “Excellent Quality”, “Good Quality”, “Acceptable Quality”, “Moderately Polluting”, “Highly Polluting”, and “Extremely Polluting”. This linguistic classification using fuzzy logic will be helpful as a decision support system to provide an outline for the prioritization of plans for wastewater management based on the values of the indices developed.  相似文献

The revelatory paper, “Dilemmas in the General Theory of Planning,” by Rittel and Webber (Policy Sci 4:155–169, 1973) has had great impact because it provides one example of an emergent consensus across many disciplines. Many “problems,” as addressed in real-world situations, involve elements that exceed the complexity of any known or hoped-for model, or are “wicked.” Many who encounter this work for the first time find that their concept of wicked problems aptly describes many environmental disputes. For those frustrated with the lack of progress in many areas of environmental protection, Rittel and Webber’s work suggested a powerful explanatory hypothesis: Complex environmental problems cannot be comprehended within any of the accepted disciplinary models available in the academy or in discourses on public interest and policy. What should we conclude about the future of social improvements, and about the possibilities for rational discourse leading to cooperative action, with respect to this huge number of pressing public, environmental problems? Can we find ways to address environmental problems that improves the ability of communities to respond creatively and rationally to them? I will argue that, while the Rittel-Webber critique requires us to abandon many of the assumptions associated with a positivistic view of science and its applications to policy analysis, it also points to a more productive direction for the future of policy analysis. I will introduce “boundary critique,” developed within Critical Systems Theory (CST), an approach that offers some reason for optimism in dealing with some aspects of wickedness.  相似文献

The recent two cases related to seals in Japan illustrate the nature of the “values” created for animals in today’s societies: one that appeared in a river in Tokyo and gained a national pop star fame, the other supposedly extinct Japanese seal re-gaining an endangered status. This paper argues that the contrast of these cases exemplifies the images and values of nature are created, and the “wilderness” becomes over-romanticised and idealised as societies become further removed from the biosphere. This questions the meaning of the intrinsic value of nature—can it be totally free from our social needs and vested interest; is a truly bio-centric perspective possible? The paper suggests the irrelevance of the eco-centric- anthropocentric dichotomy to today’s social contexts where complex socio-cultural, economic, political issues are interwoven.  相似文献
