The preparation of strategic environmental assessment (SEA) inclusive sustainability appraisals (SAs) for neighbourhood plans (NPs) in England may be required when significant environmental effects are expected to arise from an NP. In this paper, we report on the result of a Ph.D. project, conducted between 2012 and 2015, in which all 15 NP SEA inclusive SAs that had been completed at the time were evaluated. In this context, the quality of SA practice was found to differ substantially. SAs were prepared either ‘in-house’ (i.e. by neighbourhood planning steering groups) or by consultants. The quality of SAs was found to be associated with their overall perceived degree of influence on the underlying NPs. Whilst the focus of this paper is on practice in England, findings are expected to be of interest to a wider international audience, in particular to those experimenting with voluntary neighbourhood/local level plan SA/SEA.  相似文献

Idiosyncratic deals (i‐deals) research focuses on the emergence of customized work arrangements employees negotiate with their employers. This article provides a critical review and synthesis of i‐deals research, combining a qualitative review of i‐deals theory and research with a supplementary meta‐analysis of 23 empirical studies (k = 27 samples, N = 8110 individuals). The qualitative review examines the conceptualization and measurement of i‐deals and identifies patterns and gaps in i‐deals research, while the quantitative meta‐analysis tests the moderating effect of societal cultures on the predictors and consequences of ideals investigated to date. In each section, attention is given to strengths and weaknesses of current approaches to i‐deals theory and research. Future research directions are identified with particular emphasis on the largely unexamined role of i‐deals from a multilevel perspective. Copyright © 2014 John Wiley & Sons, Ltd.  相似文献

Given many potential obstacles, what types of strategic plans and measures for climate protection and/or energy sustainability are more likely than others to be adopted by cities? What are the key internal and external obstacles to adopting and implementing these plans and measures? Based on data obtained from a survey conducted from 2010 to 2011 and other sources, this paper develops a framework derived from political contracting theory and strategic orientation literature to examine how public management obstacles, socio-economic factors, and political factors influence a city's likelihood of having strategic energy sustainability plans and measures in place. Moreover, this paper finds that many California cities remain reluctant to require residents and businesses to comply with more challenging sustainability measures, such as smart-growth land-use practices, and that those cities with a strategic energy sustainability plan already in place tend to be more willing to adopt smart-growth land-use measures.  相似文献

This study uses framing theory to analyze 38 studies on industry actors' climate change communication between 1990 and 2010. It identifies three consecutive phases, each characterized by one dominant master frame: in the early and mid-1990s the US fossil fuel and coal industry pushed the frame of scientific uncertainty. With the rundown to the Kyoto negotiations in 1997, the strategy shifted toward the socioeconomic consequences of mandatory emission reductions, particularly in the USA and Australia. At the same time, European industry actors started to promote industrial leadership in a climate protection, which today dominates across all the world regions. The study discusses potential triggers for the regional differences as well as the implications for further research.  相似文献

Abstract

The study tries to set up a system to extract strategic environmental assessment (SEA) in exploitation of regional development based on the present situation of environmental assessment in China. First, the article summarizes the emphasis and deficiency of international academic community’s SEA research in the past 10 years. Based on this, the article puts forward the concept and evaluation principles of regional strategic environmental assessment (RSEA). Then the article expounds the necessity of carrying out RSEA. After that, the article discusses in detail the process of RSEA, which includes defining evaluation scope, describing regional background, combing strategic behavior, designing development scenarios, predicting the pressure on environment, assessing environmental impact, screening alternatives and proposing regulation and control schemes.  相似文献

结合黄河中上游能源化工区重点产业发展战略生态风险宏观性、综合性、复杂性的特点,论文以生态风险景观评价方法及3S技术等为研究手段,综合考虑重点产业发展战略人为风险源及自然风险源,以生态风险受体和终点选择、风险源分析、暴露危害分析、生态风险综合评价及生态风险分区为评价步骤,揭示了重点产业发展战略潜在生态风险空间分异特征。研究结果表明:黄河中上游重点产业战略实施区可划分为三类生态风险监控区,生态风险重点监控区自然风险源分布集中,重点产业人为风险源和自然风险源交织在一起,极易发生生态风险放大效应,生态风险次重点监控区自然生态风险源分布较单一,局部重点产业人为风险源强度增强,将增加区域生态风险水平,生态风险监控区自然生态风险源分布范围较小,潜在生态风险水平相对较低。论文探索了战略环评生态风险评价方法和评价思路,为国内重点产业发展战略生态风险评价提供了借鉴。  相似文献

China's EIA Law does not require transboundary proposals to be assessed, despite recognition of this globally, for example in the Espoo Convention and Kiev Protocol, and in the European EIA and SEA Directives. In a transboundary context assessment within a state is unusual, as regulating these effects is primarily about the relationship between states. However where a state has more than one legal system such as in the Pearl River Delta (PRD) Region of southern China, transboundary effects should also be addressed. Yet despite the geographical connections between Guangdong Province in mainland China (where the EIA Law applies) and the Hong Kong and Macau Special Administrative Regions (which have their own provisions, neither of which requires transboundary assessments), EIA and SEA are carried out separately. Coordinated or joint approaches to transboundary assessment are generally absent, with the legal autonomy of Hong Kong and Macau a major constraint. As a result institutional responses at the policy level have developed. The article considers global experiences with regulating transboundary EIA and SEA, and analyses potential application to land use, transport and air and water planning in the PRD Region. If applied, benefits may include prevention or mitigation of cumulative effects, broader public participation, and improvements to environmental governance. The PRD Region experience may encourage China to conduct and coordinate EIA and SEA processes with neighbouring states, which has been non-existent or extremely limited to date.  相似文献

From a conservation perspective, quantifying potential refugial capacity has been predominantly focused on climate refugia, which is critical for maintaining the persistence of species and ecosystems. However, protection from other stressors, such as human-induced changes in fire and hydrology, that cause habitat loss, degradation, and fragmentation is also necessary to ensure that conservation efforts focused on climate are not undermined by other threats. Thus, conceptual and methodological advances for quantifying potential refugia from multiple anthropogenic stressors are important to support conservation efforts. We devised a new conceptual approach, the domains of refugia, for assessing refugial capacity that identifies areas where exposure to multiple stressors is low. In our framework, patterns of environmental variability (e.g., increased frequency of warm summers), thresholds of resilience, and extent and intensity of stressors are used to identify areas of potential refugia from a suite of ongoing anthropogenic stressors (e.g., changes in fire regime). To demonstrate its utility, we applied the framework to a Southern California landscape. Sites with high refugial capacity (super-refugia sites) had on average 30% fewer extremely warm summers, 20% fewer fire events, 10% less exposure to altered river channels and riparian areas, and 50% fewer recreational trails than the surrounding landscape. Our results suggest that super-refugia sites (∼8200 km2) for some natural communities are underrepresented in the existing protected area network, a finding that can inform efforts to expand protected areas. Our case study highlights how considering exposure to multiple stressors can inform planning and practice to conserve biodiversity in a changing world.  相似文献
