浅谈如何开展环境监测类设施公众开放日活动

随着城市工业化的快速发展,突发性环境污染事故逐渐增多,因此,环境公众开放日活动显得尤为重要。本文结合实际情况,探讨如何开展监测类公众开放日活动。     

基于结构方程模型的环境风险接受度影响因素分析

随着社会经济的发展和城市化进程的推进,我国环境风险事故频发。与此同时,公众对于美好环境的需求日益提升,公众与专家和政府之间的风险判断差异是不同规模的群体性事件发生的主要诱因。为识别公众环境风险接受度的影响因素,本研究基于结构方程模型分析了11种环境风险的客观风险水平和公众感知到的风险影响度、场域了解度、政府信任度、社会经济水平等因素对公众风险接受度的影响。研究结果显示,社会经济水平、风险影响度、场域了解度、政府信任度均直接影响公众的风险接受度;客观风险水平则通过风险影响度的中介作用间接影响风险接受度。因此,为在经济发展过程中降低公众风险感知偏差对生产生活的影响,我国除了通过更严格的风险管控手段降低风险事故发生概率和影响范围外,还需要通过信息公开、公众参与和生态科普等方式增强公众对风险场域的了解度和对政府的信任度以提升风险接受能力。     

Fast,cheap, and imperfect? US public opinion about solar geoengineering

ABSTRACT

Solar geoengineering, which seeks to cool the planet by reflecting a small fraction of sunlight back into space, has drawn the attention of scientists and policymakers as climate change remains unabated. Unlike mitigation, solar geoengineering could quickly and cheaply lower global temperatures. It is also imperfect. Its environmental impacts remain unpredictable, and its low cost and immediate effects may result in ‘moral hazard,’ potentially crowding out costly mitigation efforts. There is little understanding about how the public will respond to such tradeoffs. To address this, a 1000-subject nationally representative poll focused on solar geoengineering was conducted as part of the Cooperative Congressional Election Study (CCES) of the US electorate in October–November 2016. The importance that individuals place on solar geoengineering’s speed and cost predicts their support for it, but there is little to no relationship between their concerns about its shortcomings and support for its research and use. Acquiescence bias appears to be an important factor for attitudes around solar geoengineering and moral hazard.     

公众灾害风险可接受性与避灾意愿的初探——以川渝地区旱灾风险为例

在综述前人研究的基础上,以川渝地区旱灾为例,通过实地调查与访谈,从公众可接受的旱灾损失与频率、假定旱灾风险情景下的避险意愿等角度,对公众旱灾风险可接受性进行了初步探讨。结果表明,公众合理可接受的旱灾损失与频率分别在26.5%~52.8%与32.0%~64.3%区间范围内;并以一般旱灾、严重旱灾风险情景为限制线,确定了公众合理可接受风险区域;随着灾害损失风险增加,公众规避风险投资意愿呈现出中间高两头低的趋势,当灾害损失达到约50%~70%时,公众避险投资意愿达到最高,意愿避险投资占可能损失的比重约为62%。鉴于川渝地区的旱灾形势,今后旱灾风险管理的关键,一是加强对旱灾的监测与预警预报;二是完善旱灾风险的常规化管理,发展高效灌溉农业,充分利用客水资源,完善提高现有农田水网建设;三是积极探索公众-企业-政府多方共同参与的高效风险管理模式。     

中国环境影响评价中公众参与存在的问题与对策

公众参与是环境影响评价中的重要内容,在环境影响评价中发挥着特殊作用。针对目前中国环境影响评价中公众参与的实施状况,提出了公众参与意识不强、参与形式单一、信息公开不充分和公众意见未受到足够重视等一系列问题,并从宏观及具体操作上提出加强环保宣传教育、采取多样化的参与形式、建立完善的环境信息公开制度和认真对待公众反馈意见等相关的有效对策。     

Food for Thought: Audience Engagement with Sustainability Messages in Branded Content

Branded platforms are a growing “gray-zone” of marketing and media messages, in which corporations and news journalists partner to create content that supports strategic corporate goals while aligning with a publication’s scope of editorial coverage. As corporations are key influencers of and contributors to environmental communication, this trend has the potential to change environmental dialogue. In this article, we closely examine messages about food and sustainability, created in partnership by Chipotle Mexican Grill and the Huffington Post news site. We illustrate how use of a branded platform expanded the scope of environmental topics, issues, and frames that Chipotle addresses, how frames identified here connect to frames in coverage of science-related issues, as identified by other scholars, and discuss how branded platforms allow corporations to draw attention to polarizing environmental issues while protecting stakeholder relationships and brand reputation.     

Infrastructure development through PPPs in India: criteria for sustainability assessment

Public private partnerships (PPPs) allow the Indian Government to leverage private capital for meeting the widening demand-supply gap in the provision of infrastructure services. The private sector, however, prefers to limit the participation to financially attractive projects only, thereby resulting in patterns of infrastructure creation impeding the progress towards sustainable development. In order to promote sustainable development, the PPP procurement process should focus on incentivising the private sector for sustainable infrastructure development rather than concentrating on ensuring financial sustainability only. This paper discusses the principles-based PPP-specific framework that has been developed to facilitate assessment of PPP projects' progress towards sustainable development. The framework development was based on a holistic approach to sustainability assessment and subsequently validated through questionnaire survey with key stakeholders in the Indian PPP programme. This framework will provide the decision makers with appropriate decision aid for integration of sustainable development principles in the PPP procurement process.     

Result-oriented approaches to the management of drinking water catchments in agricultural landscapes

Management of water quality in drinking water catchments is of ongoing, high importance as nitrate concentrations are often still very high. We analysed the Augsburg catchment in Germany, a unique example where a result-oriented approach has been implemented. We investigated the historical evolution of the water protection programme, the result-oriented payment contracts with farmers, and farmer satisfaction with the contracts, based on interviews with the water utility and farmers as well as an analysis of the literature. Today, the water protection programme has been successfully implemented, and a significant reduction of nitrate concentration was achieved due to the following factors: (1) investment of non-negligible amounts of money for high compensation and remuneration payments, (2) different contract options, (3) farmers’ participation in the negotiation process for result-oriented payment contracts, (4) involvement of “outside” people and institutions in negotiation processes, (5) anticipation of starting a programme when nitrate levels were still far below legislative thresholds, and (6) a political and legislative framework allowing direct decisions by a water supplier.     

Environmental health in the complex city: a co-evolutionary approach

While public health and urban planning were closely linked in the past, today both domains are institutionally separate. In most cases, health intersects with spatial planning processes only through obligatory evaluations, such as environmental impact assessments, or restrictive environmental legislation. This institutionalisation of health criteria in most western countries has difficulty in dealing with recent environmental health challenges, leading to continual distrust and conflict between citizens and the government. This impasse has recently been discussed by academics who acknowledge the complexity of both city and health issues. It seems, however, that the full extent of the issue has not been covered yet, leading to recommendations and frameworks that are useful but fixed and retrospective. This paper moves beyond those fixed frameworks to develop a better understanding of the complexity of the current disconnect and explores ideas for a future planning approach, grounded on new ideas of co-evolutionary and adaptive planning.     

Supporting Diverse Data Providers in the Open Water Data Initiative: Communicating Water Data Quality and Fitness of Use

Shared, trusted, timely data are essential elements for the cooperation needed to optimize economic, ecologic, and public safety concerns related to water. The Open Water Data Initiative (OWDI) will provide a fully scalable platform that can support a wide variety of data from many diverse providers. Many of these will be larger, well‐established, and trusted agencies with a history of providing well‐documented, standardized, and archive‐ready products. However, some potential partners may be smaller, distributed, and relatively unknown or untested as data providers. The data these partners will provide are valuable and can be used to fill in many data gaps, but can also be variable in quality or supplied in nonstandardized formats. They may also reflect the smaller partners' variable budgets and missions, be intermittent, or of unknown provenance. A challenge for the OWDI will be to convey the quality and the contextual “fitness” of data from providers other than the most trusted brands. This article reviews past and current methods for documenting data quality. Three case studies are provided that describe processes and pathways for effective data‐sharing and publication initiatives. They also illustrate how partners may work together to find a metadata reporting threshold that encourages participation while maintaining high data integrity. And lastly, potential governance is proposed that may assist smaller partners with short‐ and long‐term participation in the OWDI.
