A number of EU institutions and government committees across Europe have expressed interest in developing methods and decision-support tools to facilitate consideration of the ethical dimensions of biotechnology assessment. As part of the work conducted in the EC supported project on ethical tools (Ethical Bio-TA Tools), a number of ethical frameworks with the potential to support the work of public policy decision-makers has been characterized and evaluated. One of these potential tools is the Delphi method. The Delphi method was originally developed to assess variables that are intangible and/or shrouded in uncertainty by drawing on the knowledge and abilities of a diverse group of experts through a form of anonymous and iterative consultation. The method has hitherto been used by a diversity of practitioners to explore issues such as technology assessment, environmental planning, and public health measures. From the original (classical) Delphi, a family of Delphi-related processes has emerged. As a result of the evaluation of the various Delphi processes, it is proposed that the classical method can be further developed and applied as a form of ethical framework to assist policy-makers. Through a series of exercises and trials, an Ethical Delphi has been developed as a potential approach for characterizing ethical issues raised by the use of novel biotechnologies. Advantages and disadvantages of the method are discussed. Further work is needed to develop the procedural aspects of the Ethical Delphi method and to test its use in different cultural contexts. However, utilizing an ethical framework of this type combines the advantages of a methodical approach to capture ethical aspects with the democratic virtues of transparency and openness to criticism. Ethical frameworks such as the Ethical Delphi should contribute to better understanding of and decision-making on issues that involve decisive ethical dimensions.  相似文献

The status of wild capture fisheries has induced many fisheries and conservation scientists to express concerns about the concept of using forage fish after reduction to fishmeal and fish oil, as feed for farmed animals, particularly in aquaculture. However, a very large quantity of forage fish is being also used untransformed (fresh or frozen) globally for other purposes, such as the pet food industry. So far, no attempts have been made to estimate this quantum, and have been omitted in previous fishmeal and fish oil exploitation surveys. On the basis of recently released data on the Australian importation of fresh or frozen fish for the canned cat food industry, here we show that the estimated amount of raw fishery products directly utilized by the cat food industry equates to 2.48 million metric tonnes per year. This estimate, plus the previously reported global fishmeal consumption for the production of dry pet food suggest that 13.5% of the total 39.0 million tonnes of wild caught forage fish is used for purposes other than human food production. This study attempts to bring forth information on the direct use of fresh or frozen forage fish in the pet food sector that appears to have received little attention to this date and that needs to be considered in the global debate on the ethical nature of current practices on the use of forage fish, a limited biological resource.  相似文献

The Ethical Matrix was developed to help decision-makers explore the ethical issues raised by agri-food biotechnologies. Over the decade since its inception the Ethical Matrix has been used by a number of organizations and the philosophical basis of the framework has been discussed and analyzed extensively. The role of tools such as the Ethical Matrix in public policy decision-making has received increasing attention. In order to further develop the methodological aspects of the Ethical Matrix method, work was carried out to study the potential role of the Ethical Matrix as a decision support framework. When considering which frameworks to apply when analyzing the ethical dimensions of the application of agri-food biotechnologies, it is important to clarify the substantive nature of any prospective framework. In order to further investigate this issue, reflections on the neologism “ethical soundness” of an ethical framework are presented here. This concept is introduced in order to provide more structured evaluations of a range of ethical tools, including ethical frameworks such as the Ethical Matrix. As well as examining the philosophical dimensions of the method, theoretical analysis and literature studies were combined with stakeholder engagement exercises and consultations in order to review the Ethical Matrix from a user perspective. This work resulted in the development of an Ethical Matrix Manual, which is intended to act as a guide for potential user groups.  相似文献

Nowadays many debates are going on that relate to the agricultural and food sector. It looks as if present technological and organizational developments within the agricultural and food sector are badly geared to societal needs and expectations. In this article we briefly present a toolkit for moral communication within the food chain. This toolkit is developed as part of a European research project. Next, we discuss what such a toolkit can bring about, given the characteristics of the present day agricultural and food sector and its wider context. We defend that the toolkit can be seen as one of the mechanisms that can help enterprises in the agricultural and food sector to be accountable. It should, however, be complemented with other mechanisms, first, to empower the wider public and, second, to stimulate a dialogue, on a more equal footing, between public authorities, citizens, and economic actors.  相似文献

The control and prevention of nutrient pollution from fish farming plays an essential role in the French regulatory framework. Assessing nutrient emissions from fish farms is important in terms of farm authorization, taxation, and monitoring. Currently employed strategies involve both water sampling and empirical modeling. This article reports the work and outcomes of an expert panel that evaluated existing methodologies and their possible alternatives. The development and evaluation of a nutrient-balance approach was assessed as a potential alternative to currently used methodologies. A previously described nutrient-balance model was suggested and parameterized using expert choice, and its validity and applicability were assessed. The results stress that the nutrient-balance model provides more robust and relatively conservative waste estimates compared to the currently used methodologies. Sensitivity of the approach to the uneven data quality available at farm level, difficulties of on-farm measurements, as well as model requirements and limitations are discussed.  相似文献

k -means nonhierarchical cluster analysis using farm size, slope, and distance to the nearest city center and highway as surrogates of farmland conversion. Discriminant analysis showed that the two groups derived from the cluster analysis were 98.8% accurate (P < 0.0000). Results from the statistical analysis may serve as a starting point for the identification of individual farms prone to residential development. To explain the driving forces of farmland conversion to residential uses, interviews should be conducted with farmers, landowners, and land buyers. The use of multivariate statistical techniques to identify farms in jeopardy of residential development, in conjunction with qualitative assessments that explain the probability of development of individual farms, may prove a useful strategy to understand and predict farmland conversion.  相似文献

Alaska's program for rebuilding salmon stock is calledfishery enhancement. Hatchery technology can produce dramatic increases in numbers of fish homing to selected streams. The Sheep Creek Hatchery is unusually efficient— it increases a fish run by a factor of 3000 and produces salmon at 9–11c/kg by minimizing mechanical energy inputs and human labor. The design harnesses the force of gravity and capitalizes on instinctual behavior of the fish. Since migratory fish collect protein from ocean pasturage, the technology increases the share of this resource collected and concentrated for harvest in a specific country or region. While small seaside hatcheries can solve biological problems of depleted fish stocks, economic and political considerations may preclude efficient utilization of the protein produced. Further, the potential for one state or country to concentrate fish near its shores poses new dilemmas for international regulation of harvests.  相似文献

The aim of this paper is to clarify the ethical issuessurrounding GM crops by examining the various stages or levels intheir development, production, and consumption. Previous workabout the acceptability or non-acceptability of GM crops hastended to conflate these various levels, partly as a result ofwhich GM crops are all-too-often simply said to be ``good' or``bad.' There are, though, various problems with such a binarycategorization. I look in particular at the duties of scientists,companies, regulatory systems, farmers, retailers, and consumers.  相似文献

A Framework for the Ethical Analysis of Novel Foods: The Ethical Matrix   总被引:6,自引:4,他引:2  
The paper addresses the issue of how indemocratic societies a procedure might be formulatedto facilitate ethical judgements on modernbiotechnologies used in food production. A frameworkfor rational ethical analysis, the Ethical Matrix, isproposed. The Matrix adapts the principles describedby Beauchamp and Childress for application to medicalissues, to interest groups (e.g., producers,consumers, and the biotic environment) affected bythese technologies. The use of the Matrix isillustrated by applying it to an example of a ``novelfood,' viz., a form of genetically modified maize.  相似文献

Slovene agriculture is going throughdrastic changes. Most of the land is stillowned by small farmers. The production isoriented to the market and is based on modernWestern technology. It is associated withincreasing pollution and is becoming a seriousthreat to biodiversity. Many of the wild plantsare endangered due to genetic erosion withinspecies. The traditional crops and varietiesare being replaced by imported materials andthe use of chemicals has been increasing. Manyof the traditional varieties have beenneglected and/or lost. The existing germplasmcollections are incomplete and frequently donot include traditional varieties. There areonly a few breeding organizations with limitedcapacities and collections. The legislation isnot efficient enough to protect the environmentand biotic diversity. Schools, media,religious, sport, tourist, and otherorganizations should be more active inpromoting the respect for biodiversity.  相似文献

Shields, F. Douglas, Jr. and Scott S. Knight, 2011. Significance of Riverine Hypoxia for Fish: The Case of the Big Sunflower River, Mississippi. Journal of the American Water Resources Association (JAWRA) 48(1): 170‐186. DOI: 10.1111/j.1752‐1688.2011.00606.x Abstract: Degraded streams draining low‐relief, intensively cultivated watersheds may experience periods of hypoxia or anoxia. A three‐year study of water chemistry, fish, and physical habitat in the Big Sunflower River in northwestern Mississippi coupled with continuously logged physicochemical and hydrology data provided by others showed prolonged periods of hypoxia associated with higher flows. Fish species richness was directly related to dissolved oxygen (DO) concentration (r2 = 0.35, p = 0.00004), and ordination using nonmetric multidimensional scaling (NMS) indicated strong association between fish community structure and DO. Low‐head weirs supported relatively dense and diverse fish communities and thus provided local habitat enhancement, but may create stagnant zones upstream due to backwater effects that exacerbate low DO problems. Although hypoxia has been reported for some lightly degraded rivers and floodplains, our observations suggest hypoxia in Big Sunflower River and similar systems alters fish species composition and should be remediated. Cost‐effective remediation will require better understanding of autotrophic and heterotrophic processes that control DO and the relationship of these processes to discharge.  相似文献

/ During the last decade, a major initiative for community involvement in the management of state forest lands was started in India in the form of Joint Forest Management (JFM) programs. Despite the progress and positive impacts, the JFM program is still in the experimental phase. Latent conflicts related to caste, class, and gender issues are threatening JFM institutions at the village level. The Forest Department is also facing a number of internal conflicts as it tries to adjust to its new role under JFM. Some thoughtful and creative attempts have been made to resolve these conflicts. However, a much more concerted effort is required along with creation of suitable mechanisms at local, state, and national levels to discuss and resolve present and future conflicts.  相似文献

We sampled 240 wadeable streams across Wisconsin for different forms of phosphorus and nitrogen, and assemblages of macroinvertebrates and fish to (1) examine how macroinvertebrate and fish measures correlated with the nutrients; (2) quantify relationships between key biological measures and nutrient forms to identify potential threshold levels of nutrients to support nutrient criteria development; and (3) evaluate the importance of nutrients in influencing biological assemblages relative to other physicochemical factors at different spatial scales. Twenty-three of the 35 fish and 18 of the 26 macroinvertebrate measures significantly correlated (P < 0.05) with at least one nutrient measure. Percentages of carnivorous, intolerant, and omnivorous fishes, index of biotic integrity, and salmonid abundance were fish measures correlated with the most nutrient measures and had the highest correlation coefficients. Percentages of Ephemeroptera–Plecoptera–Trichoptera individuals and taxa, Hilsenhoff biotic index, and mean tolerance value were macroinvertebrate measures that most strongly correlated with the most nutrient measures. Selected biological measures showed clear trends toward degradation as concentrations of phosphorus and nitrogen increased, and some measures showed clear thresholds where biological measures changed drastically with small changes in nutrient concentrations. Our selected environmental factors explained 54% of the variation in the fish assemblages. Of this explained variance, 46% was attributed to catchment and instream habitat, 15% to nutrients, 3% to other water quality measures, and 36% to the interactions among all the environmental variables. Selected environmental factors explained 53% of the variation in macroinvertebrate assemblages. Of this explained variance, 42% was attributed to catchment and instream habitat, 22% to nutrients, 5% to other water quality measures, and 32% to the interactions among all the environmental variables.  相似文献

Refining the Use of Habitat Equivalency Analysis   总被引:3,自引:0,他引:3  
When natural resources are injured or destroyed in violation of certain U.S. federal or state statutes, government agencies have the responsibility to ensure the public is compensated through ecological restoration for the loss of the natural resources and services they provide. Habitat equivalency analysis is a service-to-service approach to scaling restoration commonly used in natural resource damage assessments. Calculation of the present value of resource services lost due to injury and gained from compensatory restoration projects is complicated by assumptions concerning the within-time period crediting of losses and gains. Conventional beginning-of-period accounting leads to an underestimate of the loss due to injury and an overestimate of the gains from compensatory projects in cases with linear recovery projections. The resulting compensatory requirement is often insufficient to offset the true loss suffered by the public. Two algebraic equations are offered to correct for these estimation inaccuracies, and a numerical example is used to illustrate the magnitude of error for a typical, though hypothetical, injury scenario.  相似文献

本文利用能值分析的方法,分析了苏州城市生态系统的各种生态流,并建立了苏州城市生态系统可持续发展能值评价指标体系,评估其可持续发展程度,并对其能值指标的发展进行了预测。研究结果显示,2007年苏州市系统利用总能值达到616.71×1021sej,能值自给率仅为35.5%,环境负载率达到61.67。与其他国家和地区能值指标对比得出,苏州市是一个高度外向型生态经济系统,其系统的发展高度依赖于外界资源的输入,面对现在不稳定的世界经济发展和外部环境,苏州市必须加大系统自身的供给能力,提高系统自身的稳定性;发展循环经济,降低系统环境负载率;加强高科技和人才投入,提高系统可持续发展潜力。  相似文献
