The most important driver for management is successful business that increases its value to shareholders. The adoption of environmentally responsible business practices can open up an additional range of opportunities for companies, for example by improving material efficiency. The choice to improve environmental performance of a company tends to also improve its financial performance. In this paper, our aim is to study the value of sustainability in process and mining industry from the perspective of interest groups such as investors, customers and the public, by using case examples. Interviews and workshops were employed to investigate whether or not investors and customers are interested in sustainability in the process and mining industries. We also illustrate how easy it can be to jeopardize corporate reputation through. The present situation and challenges faced in bringing sustainability into everyday business practices are summarized and proposals made concerning ways to achieve increased sustainability.  相似文献

This paper claims that participatory approaches to water resource management in New Zealand are highly influenced by how institutional and community actors understand and practise democracy, including indigenous Māori rights under the Treaty of Waitangi. Drawing on case study analysis from a six-year research programme in which the aim was to evaluate existing and new methods for participatory decision-making, we highlight how different but co-existing democratic beliefs and practices, referred to as democratic logics can shape relationships between governance/decision-making bodies and affected communities. One particular case is examined in detail to illustrate how the various “logics” were strengthened, extended and challenged through participatory research methodologies. Our key message is that revealing and articulating existing democratic logics for participation can help promote and facilitate new participatory approaches, as well as increase robustness and community buy-in to local government decision-making.  相似文献

当前我国环境群体性事件呈高发态势。根据引发事件事实状态的不同可将其分为事前预防型环境群体性事件和事后救济型环境群体性事件。预防型环境群体性事件中公众所抵制的是有关环境风险的决策结果,实质上是在主张环境公共决策过程中认知风险的权利。着眼于预防型环境群体性事件所针对的环境公共决策过程,主要运用理论分析、规范分析、比较分析的方法,从行政决策权的行使与公众参与权利的实现入手,探究环境公共决策无法取得实质合法性的根源,寻求化解之法治路径。当前环境公共决策在结构和程序上呈现出封闭性,与决策结果具有直接利害关系的公众被排除在外,其认知风险的权利得不到有效实现,风险沟通不畅导致社会可接受的风险共识不能形成,环境公共决策无法取得实质合法性,引发预防型环境群体性事件增多。由于环境风险的不确定性特征,环境公共决策中专家的理性地位被动摇,公众参与环境决策的诉求更为强烈,其对风险的认知直接决定了对最终决策结果的认可和接受程度,政府无法独占风险决策地位。在社会层面形成具体风险认知的共识以便决策结果获得普遍的认同和接受成为环境公共决策取得实质合法性的必要条件。化解预防型环境群体性事件,需要在环境公共决策过程中进行有效的风险沟通。为此,环境法应当将公众作为环境决策的合作者,要求决策者主动、全面公开决策所依据的事实和理由,对公众意见给予及时充分的回应,寻求其理解和支持;实现环境信息公开的风险沟通功能;通过程序性的设计促进风险沟通的实现,保障公众参与的有效性。当前有关立法已反映出对风险沟通的重视,但只是萌芽。  相似文献

This paper presents a multi-criteria selection of the best forest road network with the aim of achieving effective preventive and timely repressive protection against forest fires. The research was carried out in national park (NP) “Tara” at a site which is under constant threat of fire. Four variants of the forest road network were designed and analyzed against seven criteria, and the best variant was selected using entropy weight coefficients (EWC) method. The importance of these seven criteria was studied by the management of the NP “Tara.” The greatest importance was given to the criteria relating to the cost of construction and maintenance of permanent and temporary roads (47% of the total value of all criteria). The EWC method did not select the variant based on the lowest costs of construction and maintenance as the best option, but the variant whose location was the most suitable for effective defense against forest fires.  相似文献

Biodiversity and human well-being strategies are only as good as the set of ideas people think about. We evaluated value-focused thinking (VFT), a framework that emphasizes creating objectives and strategies that are responsive to the objectives. We performed a proof-of-concept study of VFT with 6 conservation planning teams at a global conservation organization. We developed a package of materials related to VFT, including meeting–session agendas, a virtual facilitation template, facilitator's guide, and evaluation questionnaires. We used these materials to test whether VFT applied in a group setting resulted in high-quality conservation strategies and participant satisfaction and whether our materials were scalable, meaning that someone newly trained in VFT could facilitate planning meetings that resulted in high-quality strategies and participant satisfaction, as compared with an experienced VFT facilitator. Net response indicated positive compelling, feasible, creative, and representative ratings for the conservation strategies per team. Participants indicated satisfaction overall, although satisfaction was greater for objectives than for strategies. Among the participants with previous conservation planning experience, all were at least as satisfied with their VFT strategies compared with previously developed strategies, and none were less satisfied (p = 0.001). Changes in participant satisfaction were not related to facilitator type (experienced or inexperienced with VFT) (p > 0.10). Some participants had a preconceived sense of shared understanding of important values and interests before participating in the study, which VFT strengthened. Our results highlight the advantages of structuring the development and evaluation of conservation planning frameworks around VFT.  相似文献

Biodiversity conservation decisions are difficult, especially when they involve differing values, complex multidimensional objectives, scarce resources, urgency, and considerable uncertainty. Decision science embodies a theory about how to make difficult decisions and an extensive array of frameworks and tools that make that theory practical. We sought to improve conceptual clarity and practical application of decision science to help decision makers apply decision science to conservation problems. We addressed barriers to the uptake of decision science, including a lack of training and awareness of decision science; confusion over common terminology and which tools and frameworks to apply; and the mistaken impression that applying decision science must be time consuming, expensive, and complex. To aid in navigating the extensive and disparate decision science literature, we clarify meaning of common terms: decision science, decision theory, decision analysis, structured decision-making, and decision-support tools. Applying decision science does not have to be complex or time consuming; rather, it begins with knowing how to think through the components of a decision utilizing decision analysis (i.e., define the problem, elicit objectives, develop alternatives, estimate consequences, and perform trade-offs). This is best achieved by applying a rapid-prototyping approach. At each step, decision-support tools can provide additional insight and clarity, whereas decision-support frameworks (e.g., priority threat management and systematic conservation planning) can aid navigation of multiple steps of a decision analysis for particular contexts. We summarize key decision-support frameworks and tools and describe to which step of a decision analysis, and to which contexts, each is most useful to apply. Our introduction to decision science will aid in contextualizing current approaches and new developments, and help decision makers begin to apply decision science to conservation problems.  相似文献

Crisis management systems should be assessed and updated in petrochemical industries due to hazards, such as fire and explosion. Successful crisis management systems can protect both personnel and property in the petrochemical industries. The present study aimed to assess crisis management systems of five petrochemical plants in terms of three aspects, including organizational aspects, human aspects, and technical aspects. A questionnaire was designed, encompassing 34 items to cover all three aspects at both management and staff levels. A multi-criteria decision making (MCDM) approach, including the entropy method and Technique for Order of Preference by Similarity to Ideal Solution (TOPSIS), was used to analyze the collected data. The outcomes of the entropy method indicated that organizational and human aspects had the greatest influence on crisis management systems of the plants with 58% and 49% importance at management and staff levels, respectively. The crisis management systems of the investigated plants were ranked and analyzed using the TOPSIS approach. The findings of this study could assist managers and other decision-makers to address the issues of crisis management systems in petrochemical industries.  相似文献
