The Delphi approach to the mediation of environmental disputes 总被引:1,自引:1,他引:1
Environmental disputes, in many countries, have taken on a ritualistic character. Their persistence, even after prolonged analysis and debate, suggests that they result from ideological rather than factual differences. Since no single ideological position holds a monopoly on the truth, effective environmental management would seem to require an integration of views, the problem being how to achieve this. One approach to this problem is illustrated in this article. Two factions in the spruce budworm dispute in New Brunswick, Canada, were engaged in a mediation exercise using the Delphi method. Details of the design and execution of this form of mediation are provided, together with an evaluation of the Delphi's effectiveness in this context. 相似文献

In 1990 the Environmental Protection Agency (EPA) began sponsoring several pilot projects in its regional offices to examine
the potential benefits of adopting a multimedia approach to facility management. This approach differs from traditional practices
at EPA in that facilities (dischargers regulated under permits issued by the agency) are managed based upon their cumulative
impacts to all media: air, water, and land. Currently, facilities are managed by separate programs at EPA that evaluate environmental
impacts from a single-media perspective.
One aspect of discharger management is the necessity to allocate limited financial resources in a way that will minimize risk
to human health and the environment. A careful, risk-based prioritization of facilities is one means of providing insight
to the most effective strategy of allocating monitoring, inspection, and enforcement resources. Prioritization from a multimedia
perspective is particularly difficult, however, since it requires translation and integration of medium-specific facility
performances, management objectives, and perceptions of risk into a cumulative rating.
A computerized decision support system (DSS) designed to guide management through the prioritization process from a multimedia
perspective was identified as a potentially valuable tool for use in the pilot projects. This article describes the development
of such a prototype, outlines the features of the completed system, and discusses its potential for use at EPA. 相似文献

In recent years there has been a startling rise in the issuance of fish consumption advisories. Unfortunately, compliance
by the public is often low. Low compliance can be due to a number of factors, including confusion over the meaning of advisories,
conflicting advisories issued by different agencies, controversies involving health benefits versus the risks from consuming
fish, and an unwillingness to act on the advisories because of personal beliefs. In some places, such as along the Savannah
River, one state (South Carolina) had issued a consumption advisory while the other (Georgia) had not, although at present,
both states now issue consumption advisories for the Savannah River. Herein we report on the development of a fish fact sheet
to address the confusing and conflicting information available to the public about consuming fish from the Savannah River.
The process involved interviewing fishers to ascertain fishing and consumption patterns, evaluating contaminant levels and
exposure pathways, discussing common grounds for the provision of information, and consensus-building among different regulatory
agencies (US Environmental Protection Agency, South Carolina Department of Health and Environmental Control, Georgia Department
of Natural Resources) and the Department of Energy. Consensus, a key ingredient in solving many different types of “commons”
problems, was aided by an outside organization, the Consortium for Risk Evaluation with Stakeholder Participation (CRESP).
The initial role for CRESP was to offer scientific data as a basis for groups with different assumptions about risks to reach
agreement on a regulatory response action. The process was an example of how credible science can be used to implement management
and policies and provide a basis for consensus-building on difficult risk communication issues. The paper provides several
lessons for improving the risk process from stakeholder conflicts, through risk assessment, to risk management. It also suggests
that consensus-building and risk communication are continuing processes that involve assimilation of new information on contaminants
and food-chain processes, state and federal law, public policy, and public response. 相似文献

Perspectives on corporate social responsibility in the chemical sector: A comparative analysis of the Mexican and South African cases 总被引:1,自引:0,他引:1
In recent years, the debate on corporate responsibility has shifted from a focus on environmental management towards a broader concept of corporate social responsibility (CSR). This article examines the chemical industry's approach to CSR from the perspective of two emerging economies: Mexico and South Africa. The global chemical industry was one of the first to respond to public concerns about environmental pollution, toxic waste and human health by adopting an industry‐wide code of practice, known as Responsible Care. This article examines the extent to which the chemical industry has responded to the broader debate on CSR. On the basis of a comparative case study, this article argues that the response to social issues by Mexican and South African chemical companies has tended to be limited to the ‘community awareness and emergency response’ (CAER) or community dialogue component of the international voluntary management framework, Responsible Care. Similarities and differences in regulatory and institutional conditions, as well as different levels of civil society engagement, reveal additional limitations for CSR, beyond that of the Responsible Care framework. This article argues that the socio‐political context influences the extent to which companies embrace CSR, especially in emerging economies, and highlights several challenges for the chemical industry in moving forward on CSR: credibility, stakeholder engagement, value‐chain accountability, disclosure and transparency. Reflecting on these challenges, the authors conclude by recommending a renewed focus on: (1) developing a broader set of CSR management practices beyond Responsible Care; (2) institutionalizing stronger accountability measures, such as reporting and verification; and (3) developing multi‐stakeholder partnerships that complement regulation and build public sector regulatory and guidance capacity. 相似文献

Life Cycle Impact Assessment (LCIA) and Risk Assessment (RA) employ different approaches to evaluate toxic impact potential for their own general applications. LCIA is often used to evaluate toxicity potentials for corporate environmental management and RA is often used to evaluate a risk score for environmental policy in government. This study evaluates the cancer, non-cancer, and ecotoxicity potentials and risk scores of chemicals and industry sectors in the United States on the basis of the LCIA- and RA-based tools developed by U.S. EPA, and compares the priority screening of toxic chemicals and industry sectors identified with each method to examine whether the LCIA- and RA-based results lead to the same prioritization schemes. The Tool for the Reduction and Assessment of Chemical and other environmental Impacts (TRACI) is applied as an LCIA-based screening approach with a focus on air and water emissions, and the Risk-Screening Environmental Indicator (RSEI) is applied in equivalent fashion as an RA-based screening approach. The U.S. Toxic Release Inventory is used as the dataset for this analysis, because of its general applicability to a comprehensive list of chemical substances and industry sectors. Overall, the TRACI and RSEI results do not agree with each other in part due to the unavailability of characterization factors and toxic scores for select substances, but primarily because of their different evaluation approaches. Therefore, TRACI and RSEI should be used together both to support a more comprehensive and robust approach to screening of chemicals for environmental management and policy and to highlight substances that are found to be of concern from both perspectives. 相似文献

The concern of this paper is a review of the urban environmental degradation and the current approach by the military (environmental task force) in solving the problem. It is based on the experience of a few states in Nigeria. The paper proposes a comprehensive urban planning approach which should be integrated with an awareness campaign. 相似文献

ABSTRACTConceptualizing and analyzing collective policy learning processes is a major ongoing theoretical and empirical challenge. A key gap concerns the role of exogenous factors, which remains under-theorized in the policy learning literature. In this paper, we aim to advance the understanding of the role that exogenous factors play in collective learning processes. We propose a typology of exogenous factors (i.e. material, socioeconomic, institutional, discursive), and subsequently apply this in a comparative study of flood risk policymaking in two municipalities in the Netherlands. We find that exogenous factors are indeed essential for understanding collective learning in these cases, as the combined influence with endogenous factors can steer similar learning processes towards different learning products. We conclude our contribution by identifying two opportunities for further developing the collective learning framework, namely regarding the distinction of varying learning products, and the dynamics of exogenous factors over time. 相似文献

Uncertainty plays an important role in water quality management problems. The major sources of uncertainty in a water quality management problem are the random nature of hydrologic variables and imprecision (fuzziness) associated with goals of the dischargers and pollution control agencies (PCA). Many Waste Load Allocation (WLA) problems are solved by considering these two sources of uncertainty. Apart from randomness and fuzziness, missing data in the time series of a hydrologic variable may result in additional uncertainty due to partial ignorance. These uncertainties render the input parameters as imprecise parameters in water quality decision making. In this paper an Imprecise Fuzzy Waste Load Allocation Model (IFWLAM) is developed for water quality management of a river system subject to uncertainty arising from partial ignorance. In a WLA problem, both randomness and imprecision can be addressed simultaneously by fuzzy risk of low water quality. A methodology is developed for the computation of imprecise fuzzy risk of low water quality, when the parameters are characterized by uncertainty due to partial ignorance. A Monte-Carlo simulation is performed to evaluate the imprecise fuzzy risk of low water quality by considering the input variables as imprecise. Fuzzy multiobjective optimization is used to formulate the multiobjective model. The model developed is based on a fuzzy multiobjective optimization problem with max–min as the operator. This usually does not result in a unique solution but gives multiple solutions. Two optimization models are developed to capture all the decision alternatives or multiple solutions. The objective of the two optimization models is to obtain a range of fractional removal levels for the dischargers, such that the resultant fuzzy risk will be within acceptable limits. Specification of a range for fractional removal levels enhances flexibility in decision making. The methodology is demonstrated with a case study of the Tunga–Bhadra river system in India. 相似文献

The present and potential adverse effects of the atmospheric input of acidic and acidifying substances on the environment
have been of significant public and scientific concern for the past several decades. This article describes the background,
design, implementation, and major accomplishments of a 6-yr integrated multidisciplinary environmental research program designed
to address the issue of the regional scale consequences of acidic deposition on the environment and human health in Alberta.
The research program was called the Acid Deposition Research Program (ADRP) and was a cooperative undertaking between industry,
the Energy Resources Conservation Board, and the government of Alberta, Canada. The research effort was designed and guided
by two external science advisory boards, biophysical and human health, to maintain objectivity and continuity from beginning
to end. Public input was sought, encouraged, and ensured by a public advisory board. The major conclusions of the ADRP are
presented as well as observations on the needs of future integrated multidisciplinary research programs. 相似文献

The increasing growth of the economy in each country necessitates a great amount of investment in infrastructure. The belief that projects involve various uncertainties, such as technical skills, management quality, and the like, indicates that most projects fail to achieve their aims, interests, costs, as well as their timeframes and space requirements. As the environment can pose significant uncertainty to any project, environmental risks should be deeply studied by project management departments. This study intends to analyze as a case the environmental risk management system within a consulting firm. From this analysis, each aspect of a project's environmental risk management is ranked using a fuzzy analytical network process (ANP), a neural network algorithm, and a decision‐making trial and evaluation laboratory (DEMATEL) methodology. From the organizational aspect, budget risk is the most significant. From the technical aspect, the risk of regulations is the most important one. Finally, the risk of project failure from poor communication is another identified main risk in this research. By studying high‐ranking items in this hierarchy, it can be understood that these criteria exist in different aspects; therefore, all aspects of the risk should be taken into account to cover and assess risk. A neural network algorithm for validating and reassessment of ranking is employed. Results of this application showed that, based on Spearman's rank correlation method, two different approaches resulted in similar rankings. Finally, some practical implications for responding to the most highly ranked risks are proposed. 相似文献

The Lyon-Turin High-Speed Rail: The Public Debate and Perception of Environmental Risk in Susa Valley,Italy 总被引:1,自引:1,他引:0
When the construction of the Lyon-Turin segment of the new European high-speed rail network was first publicly announced at
the beginning of the 1990s, it immediately found fierce opposition from the inhabitants of Susa Valley, Italy, one of the
areas to be cut across by such infrastructure. At issue were the project’s potential environmental impact and its consequences
on public health. This study intends to clarify environmental risk perception and public debate between the national government,
local advocacy groups, and the inhabitants of Susa Valley. Two major phases of public reaction were identified: (1) an initial
rebellious period of no real dialog among the project’s major stakeholders (exemplified by the popular “No TAV” [No High Speed
Train] movement), followed by (2) a yielding period of intense multilateral negotiations centered on the activities of the
“Lyon-Turin Environmental Observatory.” The results of a qualitative cross analysis of the residents’ perception of the proposed
high-speed rail revealed that public acceptance of risk in Susa Valley was influenced by the characteristics of hazards perceived
by the residents and by the communicative approach used by the project’s various stakeholders. It also emerged that early
dialog among all the parties involved was critical in forming a personal viewpoint on risk, which, once consolidated, defied
new information and perspectives. Likely, a greater and earlier care taken by the other stakeholders to inform and consult
the local population about the railway would have greatly eased the public debate. 相似文献

This paper proposes a mixed performance measurement system using a combination of evolutionary game theory and the balanced scorecard (BSC) in environmental supply chain management (ESCM) that measures and evaluates business operations using the four different perspectives of finance, customer, internal business process, and learning and growth. ESCM plays an important role in the supply chain which leads to the reduction, reuse and recycling of resources involved in both upstream and downstream activities. This paper presents guidance for practical managers in evaluating and measuring ESCM by developing a knowledge-based BSC and evolutionary game theory. The primary purpose of this paper is to apply the proposed method in a case study to one of Iran's biggest auto industry supply chain SAIPA Company. The results of this study indicate that the adoption of ESCM, in the absence of regulatory pressures and cost-saving measures is triggered by public pressures and its implementation is limited by organizational factors and strategic myopia. 相似文献

This study evaluated the impact of small boat traffic on reaction distances of Marbled Murrelets (Brachyramphus marmoratus), in the marine waters of Pacific Rim National Park Reserve, British Columbia, Canada. Observers on moving boats recorded the minimum distance the boat came to murrelets on the water, and any disturbance reaction (fly, dive, no reaction). Out of the 7500 interactions 11.7% flew, 30.8% dove and 58.1% exhibited no flushing reaction. Using a product-limit analysis, we developed curves for the proportion of Marbled Murrelets flushing (dive or flight) as a function of reaction distance. Overall, the majority of Marbled Murrelets waited until boats were within 40 m before reacting, with 25% of the population reacting at 29.2m. A stepwise Cox regression indicated that age, boat speed, and boat density (loaded in that order), significantly affected flushing response. More juveniles flushed than adults (70.1 versus 51.7%), but at closer distances. Faster boats caused a greater proportion of birds to flush, and at further distances (25% of birds flushed at 40 m at speeds > 29 kph versus 28m at speeds <12kph). A stepwise logistic regression on diving and flight responses indicated that birds tended to fly completely out of feeding areas at the approach of boats travelling >28.8 kph and later in the season (July and August). Other secondary variables included; boat density and time of day. Discussion focused on possible management actions such as the application of speed limits, set back distances, and exclusion of boat traffic to protect Marbled Murrelets. 相似文献
