Public Participation Mechanisms in Environmental Disasters 总被引:1,自引:0,他引:1
This paper examines the role of public participation mechanisms in certain major environmental disasters. It examines situations in which people’s lifestyles or their lives have been directly threatened, and thus elicited citizen participation. Threatening issues often seem morally, physically, socially, economically, religiously, and otherwise unacceptable to a group. As will be presented in this paper, citizens voluntarily participate in a community activity when they see that their way of life has been threatened. An introductory historical perspective, the legal framework upon which it is based, and background information on the participatory mechanisms, all emphasizing the importance and need for empowering citizens with participatory skills so as to bring changes in the existing educational, legal, and social systems are presented. The major environmental accidents/disasters of Minamata, Japan; Bhopal, India; Seveso, Italy; Chernobyl, Ukraine; and Exxon-Valdez, Alaska are discussed, mainly to indicate the reaction, and the participatory mechanisms used by the affected communities in each of the sudden disasters that occurred. If citizens worldwide had been active participants in the environmental issues, it is quite possible that we would have experienced fewer environmental accidents. 相似文献

The paper describes the Ecological Monitoring and Assessment Network's (EMAN) operational and program response to certain challenges of environmental monitoring in Canada, in particular, efforts to improve the ability of the network to deliver relevant information to decision makers. In addition to its familiar roles, environmental monitoring should deliver feedback to society on environmental changes associated with development patterns, trends, processes and interventions. In order for such feedback to be effective, it must be relevant, timely, useful and accessible: all characteristics that are defined by the user, not the provider. Demand driven environmental monitoring is explored through EMAN's experiences with Canada's Biosphere Reserves, the NatureWatch Program and the Canadian Community Monitoring Network. 相似文献

Risk decision-making in natural hazards encompasses a plethora of environmental, socio-economic and management-related factors, and benefits greatly from exploring possible patterns and relations among these multivariate factors. Artificial neural networks, capable of general pattern classifications, are potentially well suited for risk decision support in natural hazards. This paper reports an example that assesses the risk patterns or probabilities of house survival from bushfires using artificial neural networks, with a simulation data set based on the empirical study by Wilson and Ferguson (Predicting the probability of house survival during bushfires, Journal of Environmental Management 23 (1986) 259–270). The aim of this study was to re-model and predict the relationship between risk patterns of house survival and a series of independent variables. Various configurations for input and output variables were tested using neural networks. An approach for converting linguistic terms into crisp numbers was used to incorporate linguistic variables into the quantitative neural network analysis. After a series of tests, results show that neural networks are capable of predicting risk patterns under all tested configurations of input and output variables, with a great deal of flexibility. Risk-based mathematical functions, be they linear or non-linear, can be re-modelled using neural networks. Finally, the paper concludes that the artificial neural networks serve as a promising risk decision support tool in natural hazards. 相似文献

With the growing importance of environmental sustainability in the corporate sector, businesses are compelled to progress from assessing and benchmarking their environmental impact to making decisions on how to prioritize impact reduction alternatives. Most often, business decisions are driven by financial metrics, but with sustainability improvements becoming a business goal, it is also important to assess metrics from environmental and social spheres; nevertheless, practically and systematically performing such an assessment is challenging. We present an application of a multi-criteria decision analysis (MCDA) method that addresses the aforementioned challenges in a corporate setting. Our case study company – one of the largest inland marine freight carriers in the United States – promotes a business culture focused on financially viable, yet socially and environmentally responsible solutions. Thus, we combine life cycle analysis (LCA), financial calculation methods, and corporate surveys to quantify environmental, economic, and social performance measures, respectively. Multiattribute utility theory is integrated with analytic hierarchy processes (AHPs) and fuzzy analysis to create a carefully designed framework for corporations with diverse groups of stakeholders. With company leadership, implementation is feasible and successful at prioritizing alternatives among diverse stakeholders. The process provides a platform for negotiation and promotes discussions on decision drivers. The use of MCDA methodologies promoted the inclusion of a suite of metrics that aligned with the company's sense of social and environmental responsibility, generating an in-depth analysis of the alternatives that factored in other things besides economics. Return-on-investments (ROI) calculations, the typical approach used in the corporate setting, would have required significantly less time and effort from the company, but the results of our MCDA application indicated that inclusion of triple bottom line metrics delve deeper into stakeholder preferences. Thus, our case study company gained a holistic view of the candidate alternatives, in addition to creating a platform for structured discussions about company goals and priorities. 相似文献

高风险系统组织因素分类与绩效评价 总被引:1,自引:1,他引:0
在收集以组织绩效评价、人的可靠性和人误分析为目的的两类组织因素分类的基础上,结合问卷调查,并依据建立的概念上的组织因素分类框架,从组织的目标和战略、组织结构、资源、规程、管理功能、培训、交流、组织文化等方面确立组织因素分类指标,基本克服了传统的组织因素分类缺陷。同时,依据组织因素的分类,考虑到组织绩效评价的复杂性和不确定性,采用模糊决策方法对某组织的绩效进行评价,识别出该组织现存的主要缺陷:组织管理方面的问题以及组织的结构设计不太合理等问题。 相似文献
