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

If environmental assessment is to more effectively assist in the move towards sustainability goals, deeper consideration of substantive, value-based questions associated with this field is required. Such questions relate, for example, to the way in which we conceive of and value the environment, the various stakeholder perceptions of development and the types of knowledge most appropriate to the environmental assessment endeavour. These issues are explored in this paper, which is based on the Applied Integrative Sustainability Guide (2010) produced by the Council for Scientific and Industrial Research (CSIR) in South Africa. In so doing, the authors draw on the work of leading thinkers in the fields of complexity theory, environmental ethics, development economics and planning.  相似文献

After almost 20 years of environmental impact assessment (EIA) in Chile, in 2010 the country adopted a more strategic view in order to include sustainability objectives in the development of policies and plans: the strategic environmental assessment (SEA). For supporting this new process, the Ministry of Environment developed a series of guidelines delineating the focus and methodology for an adequate implementation of SEA. These guidelines have been widely embraced by different actors as a reference to elaborate the environmental reports. In this opinion letter, we express our view upon the advances and challenges in the development of the SEA process in Chile and the role of evolving guidelines that have shaped the current implementation. The most relevant advances are related to an increasing awareness regarding the integration of sustainability issues in decision-making and the complementarity of SEA with the elaboration of policies and plans. Challenges are still present, and they are mainly related to the practical implementation rather than the availability of guidelines, where SEA is slowly being understood as different from the traditional EIA.  相似文献

A strategic environmental assessment (SEA) framework for electricity sector planning is developed and applied to evaluate electricity supply scenarios for Saskatchewan, Canada. The overall goal of the SEA application was to identify a preferred future electricity production path, demonstrate the application of a quantitative SEA process that operationalizes sustainability principles through the use of assessment criteria, and examine the methodological implications resulting from the application of a structured SEA framework. Results of the application identified a renewables-focused electricity supply preference, but with several implications for electricity sector investment and sustainability, including increased infrastructure requirements and increased cost of electricity. Results also demonstrate a practical approach to the operationalization of sustainability through the application of assessment criteria that are linked to higher level principles. The use of structure in the SEA process provided for replicability, transparency and the ability to quantify issues of uncertainty in Plan, program and policy (PPP) decision-making, while at the same time maintaining flexibility to tailor the SEA framework to the electricity sector context.  相似文献

A number of software packages are available that are designed to facilitate making environmental comparisons between different packaging options, to facilitate ‘green’ packaging design and assessment of the environmental aspect of sustainability. Some of these (e.g. SimaPro and GaBi) are full‐fledged ISO 14040/14044‐compliant programs for life cycle assessment (LCA). Others are more limited, but are designed to be much simpler to use (e.g. COMPASS and Package Modeling). A systematic comparison of the evaluation of several packaging systems using COMPASS, SimaPro, GaBi, and Package Modeling found significant discrepancies in LCA results from different software systems. Availability of common impact categories among the software limited comparisons to four categories: greenhouse gas emissions, fossil fuel/non‐renewable energy, eutrophication, and water depletion. Given a common set of basic packaging containers as input, results from the LCA software systems being studied disagreed on which container had the greatest environmental impact, and in some cases results were more than an order of magnitude different between software. Discrepancies in results occurred in all four impact categories, and all four software systems disagreed with each other at multiple points in the comparisons. If there is to be increasing use of LCA analysis in guiding packaging design, this issue must be fully understood and resolved. Copyright © 2015 John Wiley & Sons, Ltd.  相似文献

This study uses empirical research of 145 projects on environmental impact assessment (EIA). The researchers generated and tested hypotheses based on questions about the effectiveness and quality of EIA. By means of EIA, aspects of proactive thinking have entered into procedural decisions more than previously presumed and modifications in the spatial dimensions of projects have played an especially prominent role. The three most important factors affecting the scale of general project modifications are: the degree to which the subject matter and methodological aspects of a study are prescribed by §5 of the EIA Act (Scoping); the early, intense involvement of authorities, experts, and third parties in the scoping; and the degree to which the project's effects and impacts are analyzed and forecast in the environmental impact study (EIS). EIA and EIS practice has moved beyond the ‘experimental phase’ and routines have now emerged for certain parts of the procedure.  相似文献

In an effort to mainstream environmental sustainability in the national development agenda, the Government of Lebanon is among the pioneers in the Middle East to launch the development of a national strategic environmental assessment (SEA) system that caters to the particularities of the Lebanese planning, regulatory and institutional context. This paper provides a critical overview of the approach followed by the Ministry of Environment for the development of an SEA system and its regulation. It also makes recommendations for facilitating SEA implementation and presents some of the early outcomes resultingfrom awareness raising during consultation on the development of the proposed system  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

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

Plastic or bioplastic? Which is the least impactful flexible packaging solution for the environment? In literature, few works try to answer this question, and most of them are focused on food packaging applications, comparing only polylactic acid (PLA) with polyethylene terephthalate (PET) or other virgin plastics. Besides these lacks in the literature, this work aims at contributing to the scientific knowledge, helping in the meanwhile packaging companies to choose the best solution also for hygienic and sanitary applications as far as the environmental impact is concerned. The study is focused on the life cycle assessment of four solutions made of maize starch, PLA and polybutylene adipate terephthalate (PBAT), low-density polyethylene (LDPE) and a recycled LDPE (R-LDPE). The functional unit was a flexible packaging containing 10 sanitary towels. Primary data were retrieved thanks to an Italian company, whereas secondary data were extracted from the Ecoinvent 3.7 database. The SimaPro 9.4 software has been used to calculate the global warming, water consumption, acidification and abiotic depletion of elements and fossil fuels of each packaging solution. The results show that the raw materials and packaging production are the most impactful phases during the life cycle of plastics and bioplastics packaging, if compared to the distribution phase, the auxiliary materials involved and the final disposal. Great benefits could be gained using recycled plastics, which allow to reduce the extraction of virgin materials and overall appear as the best solution from an environmental point of view to package also sanitary products.  相似文献

In response to the lead article in this edition, we have the following observations made mostly on our professional practice. First, good scoping is essential for effective impact assessment (IA) but is rarely done well. Second, interdisciplinary teams are also essential for effective IA and are often used. Third, the use of sustainability as a tool for doing IA is intellectually attractive but may conflict with IA legislation and so should be used only with care.  相似文献

Sustainable development is a commonly quoted goal for decision making and supports a large number of other discourses. Sustainability appraisal has a stated goal of supporting decision making for sustainable development. We suggest that the inherent flexibility of sustainability appraisal facilitates outcomes that often do not adhere to the three goals enshrined in most definitions of sustainable development: economic growth, environmental protection and enhancement, and the wellbeing of the human population. Current practice is for sustainable development to be disenfranchised through the interpretation of sustainability, whereby the best alternative is good enough even when unsustainable. Practitioners must carefully and transparently review the frameworks applied during sustainability appraisal to ensure that outcomes will meet the three goals, rather than focusing on a discourse that emphasises one or more goals at the expense of the other(s).  相似文献

Fourteen years since the implementation of the European SEA Directive, the effectiveness of the English system of Local Plan sustainability appraisals/strategic environmental assessments (SA/SEAs) is analysed, based on 15 case studies, five interviews, and questionnaires of 11 planners. Substantively, SA/SEA leads to fine-tuning of plan policy wording and a more robust choice of development sites, but to only limited wider influence on the plan. Normatively, there seems to be a direct conflict between the requirement that Local Plans must provide enough housing for ‘objectively assessed need’, and environmental protection. From a pluralist perspective SA/SEA reports are very long, and although the statutory consultees often comment on them, the public do so only infrequently. It is in the transactive dimension that the largest changes have taken place: both consultants and planners have had to do more with less. This does not yet seem to have negatively affected the other effectiveness dimensions, but may not be sustainable over time.  相似文献

Monitoring nutritional parameters is an integral part of hemodialysis (HD) patient treatment program. The purpose of this study was to evaluate the impact of the personalized nutritional counseling (PNC) on calcium–phosphorus metabolism, potassium, albumin, protein intake, interdialytic weight gain (IDWG), body composition parameters and fluid overload in HD patients. This was a multicenter longitudinal intervention study with 6 months of follow‐up and 731 patients on maintenance HD from 34 dialysis units in Portugal were enrolled. Biochemical and body composition parameters were measured at baseline, 1, 3 and 6 months after the PNC. Patient's mean age was 64.9 (95% confidence interval [CI]: 63.8–66.0) years and mean HD time was 59.8 (95% CI: 55.3–64.3) months. Regarding data comparison collected before PNC vs. 6 months after, we obtained, respectively, the following results: patients with normalized protein catabolic rate (nPCR) ≥ 1 g/kg/day = 66.5% vs. 73.5% (P = 0.002); potassium > 5.5 mEq/L = 52% vs. 35.8% (P < 0.001); phosphorus between 3.5 and 5.5 mg/dL = 43.2% vs. 52.5% (P < 0.001); calcium/phosphorus (Ca/P) ratio ≤ 50 mg/dL = 73.2 % vs. 81.4% (P < 0.001); albumin ≥ 4.0 g/dL = 54.8% vs. 55% (P = 0.808); presence of relative overhydration = 22.4% vs. 25% (P = 0.283); IDWG > 4.5% = 22.3% vs. 18.2% (P = 0.068). PNC resulted in a significant decrease in the prevalence of hyperkalemia, hypophosphatemia and also showed amelioration in Ca/P ratio, nPCR and an increase in P of hyphosphatemic patients. Our study suggests that dietetic intervention contributes to the improvement of important nutritional parameters in patients receiving hemodialysis treatment.  相似文献

The validity of hemoglobin A1c (HgbA1c) is undergoing increasing scrutiny in the advanced CKD/ESRD (chronic kidney disease/end‐stage renal disease) population, where it appears to be discordant from other glycemic indices. In the Glycemic Indices in Dialysis Evaluation (GIDE) Study, we sought to assess correlation of HgbA1c with casual glucose, glycated albumin, and serum fructosamine in a large group of diabetic patients on dialysis. From 26 dialysis facilities in the United States, 1758 diabetic patients (hemodialysis = 1476, peritoneal dialysis = 282) were enrolled in the first quarter of 2013. The distributions of HgbA1c and the other glycemic indices were analyzed. Intra‐patient coefficients of variation and correlations among the four glycemic indices were determined. Patients with low HgbA1c values were both on higher erythropoietin (ESA) doses and more anemic. Serum glucose exhibited the highest intra‐patient variability over a 3‐month period; variability was modest among the other glycemic indices, and least with HgbA1c. Statistical analyses inclusive of all glycemic markers indicated modest to strong correlations. HgbA1c was more likely to be in the target range than glycated albumin or serum fructosamine, suggesting factors which may or may not be directly related to glycemic control, including anemia, ESA management, and iron administration, in interpreting HgbA1c values. These initial results from the GIDE Study clarify laboratory correlations among glycemic indices and add to concerns about reliance on HgbA1c in patients with diabetes and advanced kidney disease.  相似文献

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

Poverty Reduction Strategy Papers (PRSPs) are a central instrument in international development cooperation and of key importance in guiding donors' policies towards southern recipients. However, many aspects of the PRSP have been criticised by a variety of development stakeholders. A checklist of 85 questions has been developed to analyse the inclusion of aspects of sustainable development in PRSPs and to point to sustainability challenges and opportunities. It thus facilitates targeted advice and quality improvements. The checklist was applied to a selection of 12 PRSPs of developing countries. The results reveal an insufficient integration of the ecosystem services concept, of biodiversity and of climate issues. Property rights, gender issues, water and energy are as a rule well elaborated. PRSPs show significant variation in the integration of environmental sustainability issues. Sustainability assessments can contribute to significant improvements between first and second generation PRSPs provided the assessments are supported by a strong institutional framework and a dedicated political commitment towards sustainability.  相似文献
