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

Voluntary environmental governance is a widely used policy approach that has been criticized for its lack of effectiveness. This raises fundamental questions about how to design processes that can advance voluntary programmes in a way that makes them more successful. In this paper, we analyse a government-initiated dialogue process to phase out hazardous chemicals through voluntary action by the Swedish textile industry. The analysis shows that information transfer primarily motivated business participation, while consumer pressure, regulatory threats and traditions of government–business cooperation played minor roles. The institutional design of the dialogue ensured close interaction within a homogeneous group, but collective actions were limited by disagreement about the problems to be addressed, prior unilateral environmental commitments by leading companies, and ambivalent engagement. This case provides valuable insights into the effect of institutional design on the actual interplay between business and government and its effects on voluntary governance.  相似文献

日本与我国在历史上同属传统的东亚小农经济国家,在社会、经济、文化等方面的发展历程和存在的问题具有共通性。日本的农村生态环境管理随社会经济发展不断调整适应,政府也数次推动乡村振兴。对比研究中日两国农村环境管理及其背后的社会经济因素,虽然两国在农村环境管理上有相似性,但也有较大不同,我国不能完全照搬日本的农村环境管理体制机制,必须走一条适应我国国情的特色道路,循序渐进推进农业农村污染防治。在开展农村环保工作的具体举措上,日本也有较多可借鉴之处:一是以完善的法规政策体系保障农村环境管理;二是以精准的财政补贴支撑农村环境管理;三是以科学的规划和技术标准体系服务农村环境管理;四是以规范的行业和市场服务体系推动农村环境管理;五是以亲民务实的环境宣传教育助力农村环境管理。  相似文献

在我国生态文明建设大背景下,土壤环境污染问题正受到广泛关注。如何通过规划手段加强土壤污染防控和管治,已成为学术界和管理部门的共同关注点。本文结合《土壤污染防治行动计划》和《土壤污染防治法》,对新时代土壤环境规划的基本概念和编制框架进行了探索,通过对土壤环境规划思路、基本内容、编制步骤等问题的讨论,为新时代土壤环境规划的深入开展提出建议,包括:加快健全土壤环境规划的规范和标准,为规划提供技术支撑;加强土壤环境规划的作用和地位,促进土壤环境规划与水、大气环境规划的融合;进一步完善土壤环境法律法规,构建土壤环境规划保障体系等。  相似文献

本文结合重庆市空气质量限期达标规划编制案例,介绍了城市空气质量达标规划编制中的几个关键技术及其具体应用,包括本地化污染源排放清单编制、污染物来源解析、污染物排放形势预测与减排潜力分析以及大气环境容量核算等。本地化污染源排放清单是城市空气质量达标规划编制的基础,针对现有污染源制定科学合理的减排方案是达标规划的核心内容。分析不同区域的污染物组分浓度特征、污染源贡献以及未来污染排放形势预测,有助于识别出制约未来空气质量达标的关键因素及污染源。基于污染源减排潜力和污染传输矩阵制定的污染源减排方案更具合理性和可行性,应用空气质量模型估算大气环境容量可为规划目标可达性提供依据。  相似文献

"十四五"时期是进一步巩固和提升环境质量改善成果、切实改善人民群众生存环境的关键时期。展望"十四五",应从发展的视角看总量控制与环境质量控制所面临的问题与困难,在考虑历史因素的基础上兼顾地区间的公平与效率,切实发挥环境管理对高质量发展的推动作用,迈向"环境质量导向的总量控制"。要落实改进总量控制和质量控制效果的新举措,进一步推动建立环境质量与总量控制的量化联动关系,推动城市—单元—行业的精细化总量控制管理,丰富总量控制要素,强化服务于总量控制的能力建设,建立总量控制目标下公平的环境责任划分制度。  相似文献

中国的生态环境建设,经历了新中国建立之初生产力低下的农耕文明、改革开放后的工业文明、迈向生态文明的三大阶段,每个阶段都有自身的特质、挑战、应对和成效。从1949年到改革开放前,中国整体上表现为农耕文明特征,自然灾害频发、粮食生产短缺、城市化水平低下。为了跳出"马尔萨斯陷阱",新中国的缔造者带领人民治理水患,兴修水利,拓荒垦殖,问题得到缓解但没有得到解决,贫困落后依然,没能彻底摆脱"马尔萨斯魔咒"。改革开放后,工业化快速推进,城市化加速发展,使农民得以从土地中解放出来,极大地提升了劳动生产力;同时也使土地得以从农民手中部分释放出来,不仅大幅提升了土地资源价值,也使土地得以休养生息自我生态修复。虽然快速的工业化、城市化进程大幅提升了生产力、积累了巨量的物质财富,但是进入21世纪以来,中国的发展逼近工业文明的生态红线、环境底线和资源上线,可持续发展挑战不断凸显。2010年后,中国全面启动生态保护、污染控制和资源节约的转型发展进程,高质量、大力度建设生态文明,推进人与自然的和谐 发展。  相似文献

The present study investigated the fate and transport of two significant anions through soil to explore their potential as groundwater contaminants. The retention properties of chloride and sulfate in soils having several significantly different characteristics (soil‐1 and soil‐2) were determined using adsorption test and adsorption‐diffusion column experiments. The maximum adsorption capacity of chloride was 3.7 and 1.16 mg/g, respectively, in soil‐1 and soil‐2, with organic matter (OM) content of 3.92% and 4.69%, respectively. The sulfate adsorption obtained was 24.09% and 13.83%, respectively, in the two soils. The anions exhibited monolayer adsorption in the soils with replacement of hydroxyl ions from soils as the major mechanism of adsorption. On the other hand, the adsorption capacities obtained from the adsorption‐diffusion column experiment were about 100 times lower compared to that of the column tests of both of the soils. The maximum adsorption capacity of chloride was 0.03 mg/g and 0.01 mg/g, respectively, in soil‐1 and soil‐2, whereas that of sulfate was 0.04 mg/g and 0.03 mg/g. The empirical relation for depth of penetration (d) from a known spillage onto the soil surface was determined as a function of sorption capacity (S) and initial anion concentration (C) as = 0.0073e(?57S)C and = 0.0038e(?35S)C for chloride and sulfate, respectively.  相似文献

There is overwhelming scientific consensus that environmental change is currently having ecological and socioeconomical impacts at the micro and macrolevel. Over the coming decades, the impact of development, climate change, and urbanization on the ecosystem is likely to become even more ruthless in the Sundarbans. Like many other ecologically sensitive areas, the Sundarbans of the Indian state of West Bengal and of Bangladesh are being stressed climatically to the extreme due to their geographical location. This study explores both the ways in which residents of communities in the West Bengal and Bangladesh Sundarbans perceive changes in the environment, as well as intergenerational changes in livelihoods to be driven in a large part by environmental changes. Persons from a total of 368 households were interviewed using a structured interview tool. As an example of differences in perception between residents of the two areas, survey respondents from communities of the Sundarbans of Bangladesh were more likely to perceive that rainfall amounts are changing than did the residents interviewed from the Sundarbans of West Bengal. From the sample data, it is shown that in the Sundarbans of Bangladesh, 59% of the respondents, as compared to 63% of the respondents in West Bengal, reported that they had chosen to enter their parents’ occupations. From the multivariate logistic regression analysis, it was observed that, especially in Bangladesh when compared to West Bengal, the state of the environment plays a vital role in whether respondents adopt occupations other than those of their parents.  相似文献
