The need to better assess and manage the cumulative effects of human development is well recognized; however, the practice of cumulative effects assessment has been constrained by the current project-based approach. Further, the broader regional and strategic frameworks designed to ensure a more proactive and futures-oriented cumulative effects assessment have, ironically, remained divorced from current practice and from each other. In response, in 2008, the Canadian Council of Ministers of the Environment and various federal and provincial agencies identified the notion of ‘regional strategic environmental assessment’ as a means to integrate the current silos of environmental assessment in Canada and improve the overall practice of cumulative effects assessment. In this paper we report on the ongoing initiative to advance regional strategic environmental assessment, and present a conceptual basis and methodological framework for its development and application. 相似文献

Formal safety assessment (FSA) is a structured and systematic methodology aiming at enhancing maritime safety. It has been gradually and broadly used in the shipping industry nowadays around the world. On the basis of analysis and conclusion of FSA approach, this paper discusses quantitative risk assessment and generic risk model in FSA, especially frequency and severity criteria in ship navigation. Then it puts forward a new model based on relative risk assessment (MRRA). The model presents a risk-assessment approach based on fuzzy functions and takes five factors into account, including detailed information about accident characteristics. It has already been used for the assessment of pilotage safety in Shanghai harbor, China. Consequently, it can be proved that MRRA is a useful method to solve the problems in the risk assessment of ship navigation safety in practice. 相似文献

This paper reviews the current framework for, and practical application of, environmental impact assessment (EIA) in Malaysia and assesses the progress made towards adoption of strategic environmental assessment (SEA). EIA legislation was first introduced in 1987 and much progress has been made in enforcing compliance with the requirements. More recent moves towards devolution of EIA control to the states are an indicator of the influence that EIA is making, although there are still many practical constraints to be overcome. Even more recently, Malaysia has used SEA for area-wide schemes: the potential for this take up is evaluated. Despite many problems, the EIA process continues to function and evidence of an emerging commitment to SEA bodes well for the future. 相似文献

The risk assessment system has been applied to the information security, energy, medical and other industries. Through the risk assessment system, it is possible to quantify the possibility of the impact or loss caused by an event before or after an event, thereby avoiding the risk or reducing the loss. However, the existing risk assessment system architecture is mostly a centralized architecture, which could lead to problems such as data leakage, tampering, and central cheating. Combined with the technology of block chain, which has the characteristics of decentralization, security and credibility, collective maintenance, and untamperability. This paper proposes a new block chain-based risk assessment system architecture and a consensus mechanism algorithm based on DPOS improvement. This architecture uses an improved consensus mechanism to achieve a safe and efficient risk assessment solving the problem of data tampering in the risk assessment process, avoiding data leakage caused by improper data storage. A convenient, safe and fast risk assessment is achieved in conjunction with the improved consensus mechanism. In addition, by comparing existing risk assessment architecture, the advantages and impacts of the new block chain-based risk assessment system architecture are analyzed. 相似文献

This paper reviews the status of the environmental assessment (EA) system in Singapore and attempts to evaluate the potential for adoption of strategic environmental assessment (SEA). In Singapore, the colonial legacy of the planning system has resulted in similar processes being adopted to the British planning system and similar resistance to that previously experienced in the UK towards EA. This research indicates that the benefits of EA are not being achieved and that the demise of the natural environment in Singapore is being severely affected as a result. The terminology of SEA is not recognised, although it is claimed that environmental considerations are included in the sophisticated concept planning system that follows a ten-year cycle. Evidence collected suggests that other considerations perceived to be more important relating to economic, technical and social issues far outweighany emphasis on the environment. 相似文献

Impact assessment (IA) has become one of the most prevalent environmental policy instruments today. Its introduction under the National Environmental Policy Act (US) in 1969 was revolutionary. Perhaps it is not surprising, then, that such a widely used tool has received its share of criticism, including that it fails to meet some of its fundamental goals. Over the last fifty years, IA has broadened in scope and application and embraced new techniques. It has followed evolved, but has not changed fundamentally.We believe that IA must continue to change to meet the societal and environmental challenges of the 21st century. But will it be enough for IA to progress through incremental change (evolution), or is a complete overhaul of impact assessment (revolution) needed? We provide some ideas as to what ‘evolution’ and ‘revolution’ may look like, but rather then offering a definitive way forward now, we invite stakeholders to present their thoughts and suggestions at the IAIA19 Annual Conference in Brisbane, which carries the same theme as the title of this article. 相似文献

The Sustainable Development Goals (SDGs) are receiving increasing attention in the private sector; however ex post assessment of operational sustainability performance remains well in advance of ex ante sustainability assessment of capital projects. It is also not yet commonplace to structure emergent forms of sustainability assessment to support the SDGs explicitly. This article reviews theoretical frameworks that aim to conceptualise sustainability assessment, and then explores the potential to develop SDG-focussed forms for use at the project-level. The extent of enhancement needed to current practice is illustrated using the case study of the Asian Development Bank. This analysis reveals that sustainability is being presented as a goal of project-level assessment and there has been progress towards delivering on this by, in particular, extending the thematic coverage. Amongst the key challenges remaining are how to address trade-offs (typically unavoidable for projects) and how to connect the SDGs, set at a global level, to the local-level where projects are considered. These findings, which reveal the gap between theory and practice, can inform efforts to develop SDG-focussed sustainability assessment. 相似文献

Canadian environmental assessment has evolved significantly from the embarrassing Wreck Cove hydroelectric project experience in the mid-1970s to the more exemplary case of the Voisey's Bay Mine and Mill project, approved in 2002. Over this period, policy and law reforms have slowly made federal assessment requirements more demanding, open and mandatory. Viewed from a sustainability perspective, this evolution has been generally positive, but insufficient. While further improvements are possible and desirable, the experience of process reform in Canada so far suggests that they will be resisted and gradual. 相似文献

Background Applied ethics plays a critical role in engineering, health, business, and law. Applied ethics is currently a required component of the pre‐practice education for these professions, yet the literature suggests that challenges remain in how we define, instruct, and assess professions‐based ethics education. Purpose Based on the on going debate associated with the instruction and assessment of applied engineering ethics, an exploratory investigation was performed to determine what could be learned by looking across professions. Scope /Method Ethics, as an educational topic, can be very broad in scope. This study was limited to literature at the intersection of ethics terminology, historical development, instruction, and assessment within engineering, health, business, and law. Many references associated with each profession and the input of profession‐specific content experts informed the literature survey. Conclusions Ethics within the engineering, health, business, and law professions have historically developed in isolation. Even case studies, which the engineering profession seems to have adopted from law, are framed differently within engineering. There are common lines of debate related to instructional methods, curricular methods, and instructor qualifications, but no profession has resolved these debates. A common trend in applied ethics research is a focus on assessment of student learning, rather than evaluation of instructional methods and/or curriculum incorporation methods. Assessment tools have been developed and applied widely for many years in several of the health care sub‐disciplines, business and law. An engineering‐specific applied‐ethics assessment tool has recently been developed, but has yet to see extensive application. 相似文献
