Metagovernance and policy forum outputs in Swiss environmental politics

Policy forums are lightly institutionalized and stable forms of governance networks that include administrative authorities, interest groups, and scientists. They are said to produce different types of outputs, from simple actor coordination to position papers and implementation documents, but their productivity has also been questioned. Metagovernance strategies can improve the capability of policy forums to produce outputs. To determine how different metagovernance strategies influence the capability of forums to produce joint position papers, 29 policy forums in the Swiss environmental sector are compared through a qualitative comparative analysis. Results indicate that metagovernance strategies such as state actors as forum members or majority decision rules need to be combined with small forum size or low actor heterogeneity. Furthermore, forum foundation by the state complicates the production of position papers.     

Reinventing the bicycle: how calculative practices shape urban environmental governance

The concept of sustainability transitions has become increasingly prominent in academic and policy discourses during recent decades, but the importance of the link between knowledge-producing epistemic practices and urban governance has been underappreciated in this discourse. Based on a case study of cycling in Copenhagen between 1900 and 2015, and drawing upon a governmentality-inspired analytical framework, this research demonstrates that transformative governance may be initiated by epistemic practices that render urban systems visible in other ways. Urban cycling has been reconstructed over time in Copenhagen as a traffic safety ‘problem’, a component of the experiential and liveable city, and a health-producing (and hence economically valuable) regional transport mode. The research findings emphasise that epistemic practices can provide a powerful stimulus for creating changes in urban governance. The results also provide support for initiatives to broaden the terms of academic debate on sustainability transitions.     

开放经济、环保财政支出与污染治理——来自中国省级与行业面板数据的经验证据

首先按照各省环保财政支出占GDP比重与按主成分分析法计算的地方环境污染物排放综合指数的排名情况把中国30个省份分成两个区域,区域1环保财政支出污染治理效应较强,区域2环保财政支出污染治理效应较弱。区域1包括北京、海南等14个省市,区域2包括天津、上海等16个省市。其次基于2007—2014年中国省级和行业面板数据,分析开放经济、环保财政支出对污染治理的影响。最后借鉴门限回归模型检验开放经济是否存在环保财政支出与污染治理的门槛效应。结果显示:(1)环境污染物排放存在区域差异和行业差异,区域1呈现出开放程度和污染物排放双低的特征,而区域2则表现为双高特征。制造业、电力、煤气及水的生产和供应业污染物排放较高,采掘业污染物排放年均增长速度最快。(2)样本期内省级和行业面板数据均表明开放经济与环境污染物排放显著负相关,对外开放不是助推环境污染的原因。(3)中国环保财政支出与环境污染物排放显著负相关,环保财政支出具有显著的污染治理效应。(4)开放经济对环保财政支出的污染治理效应具有门槛效应,当进口和出口贸易总额高于门槛值-1.221、-1.016时环保财政支出的污染治理效应很难发挥。(5)以进、出口贸易总额为门槛变量时,有107个观测值低于门槛值,占总观测值的44.58%,其中有59个位于区域1,占55.14%。鉴于此应继续加大环境保护财政支出,进一步提升环保财政专项支出在GDP中所占比重,保持适度的对外开放,优化能源消费结构和实现产业结构升级,全面改善环境质量,提升开放经济下环保财政支出的污染治理效应。     

特朗普“去气候化”政策对全球气候治理的影响

美国特朗普政府宣布退出《巴黎协定》是当前全球气候治理中最受舆论关注的问题,对事态发展趋势的判断和事件影响的评估是最为亟需的。本文系统分析了特朗普政府上任后推行的一系列"去气候化"政策,以及其退出《巴黎协定》的主要动因和可能形式,同时量化评估了这些内政外交的"倒退"对美国实施国家自主贡献目标以及全球气候治理格局的实质影响,并据此提出了中国应对全球气候治理新形势变化的对策和建议。研究表明,特朗普政府"美国优先"的能源政策根植于复兴制造业和加大基础设施投资的经济利益动机,随着特朗普"去气候化"进程持续发酵,诸多气候政策面临存续风险,美国实施国家自主贡献将面临严峻挑战,"倒行政策"将有可能使美国温室气体排放出现反弹。如果不考虑中、高危气候政策,美国2025年温室气体排放也仅能相对2005年下降11.0%—14.9%,距离下降26%—28%的国家自主贡献目标相去甚远。同时,特朗普政府拒绝继续履行向发展中国家提供气候资金支持的义务,将有可能导致绿色气候基金拖欠资金总额上升117%,并进一步挫伤全球低碳投资的信心。没有美国的全球气候治理3.0时代将呈现出新的复杂特征,并不可避免地造成减排、资金和领导力缺口的持续扩大,也不排除后续会出现消极的跟随者,整体进程将可能进入一个低潮周期。虽然国际社会对中国引领全球气候治理充满期待,但中国仍应审慎对待,长远谋划应对气候变化的内政外交战略,而不应将"气候举旗"看作是一蹴而就的短期策略,对各种要求中国发挥"领导作用"的说法保持清醒头脑。在今后气候谈判中,美国仍有较大可能会二次"要价",中国作为排放大国的压力依然不容小觑,中美气候关系需要再定位。     

Urban sustainable energy development: A case study of the city of Philadelphia

Cities throughout the world are key sites for energy sustainability activities. However, analysis of such efforts to date has focused on a sub-set of atypical cities: early adopters and/or world cities. This article undertakes a case-study analysis for an ordinary city, Philadelphia, PA in order to assess the extent to which prior research provides adequate policy explanation for ordinary cities and to gain empirical insight on two under-researched aspects: policy actors, and the policy-making and implementation sites (action sites) for urban energy sustainability. Overall, the types of policy drivers, modes of governance, and enabling factors and barriers in the Philadelphia case fit with prior studies. Focusing on actors and action sites, however, offers insight on the city’s relative policy-making approach based on “non-controversy”, the key role of third-sector actors in both policy-making and implementation, and the diversification of action sites through external-level policy-making operationalised locally nevertheless at the expense of reduced control by urban actors. These findings lead to recommendations for urban energy sustainability research and practice.     

Emerging dynamics of environmental governance in northern post-productivist regions

The northern, resource-dependent regions of Canada have long faced distinctive social, economic, and environmental challenges and vulnerabilities. However, these regions and communities increasingly find themselves in a transitional and post-productivist context – the implications of which are largely unclear. Therefore, research is needed to identify the current and emerging challenges facing such regions and how environmental governance and planning must adjust to meet these challenges. We utilise the case study of the Northeast Superior region of Ontario to identify and analyse the dynamics developing in post-productivist, resource-dependent regions and what the implications may be for environmental governance. Several key themes and issues that emerged include an increasingly pluralistic context, new regionalism and north–south tensions, First Nation initiatives and power imbalances, and northern identities which are tied to ideas of historical resource-dependence, remoteness, and intimate and complex links to the landscape, all of which inform environmental governance and sustainability debates. As a result, the Northeast Superior case provides insight into these ongoing dynamics which encompass individuals, government, industry, organisations, and the landscape, with the resultant lessons being transferable to initiatives in other northern, remote, and circumpolar regions.

创意产业集聚区外部交往空间规划探索——“心理-行为-空间”互动视角下的实证研究

创意产业集聚区在促进创意产业发展、优化城市空间结构等方面具有重要意义,而以满足创意阶层特征和需求的创意产业集聚区内部公共空间规划的研究相对较少。从创意阶层交往的“心理-行为-空间”这一互动视角出发,选取南京具有代表性的“创意东8区”为研究对象,通过调查问卷、深入访谈和实地观察对创意阶层的“交往心理-交往行为-交往空间”进行了研究。在此基础上,从人口交往空间、中心交往空间、节点交往空间、道路交往空间等方面提出符合创意阶层心理和行为特征,并能促进交往产生的外部交往空间规划设计建议。     

“地球工程”作为减缓气候变化手段的几个关键问题

减缓气候变化可以在大的地理尺度上以工程技术手段来实施。地球工程包括所有能源生产和消费以外的、不涉及工业生产过程管理的,在较大的地球尺度或规模上,去除大气中的CO2或直接控制太阳辐射而降温的各种人为的工程技术手段,主要包括三大类:绿色生物技术手段、碳捕获与埋存技术和太阳光辐射额度控制管理技术。这一类地球工程手段有着一系列经济、技术、环境、伦理、安全和不确定性含义。本文就近年来国际上关于地球工程作为减缓气候变化可能技术选择的几个关键问题开展了分析和讨论,涉及概念界定、技术特点、可能影响、治理构架等。作者认为,对于直接作用于碳的地球工程手段,如绿色生物技术手段和碳捕获与埋存技术,风险小、可操控;太阳光辐管理技术,通过人为排放到大气的SO2和气溶胶等的降温效应,来控制地球气温的上升,尽管使用的经济成本可能不高,具有实际操作可能,但其巨大的不确定性和可能的安全含义,需要引起足够的重视。从伦理上看,当代人是否有权来开展太阳光辐管理技术这类具有巨大科学不确定性的地球工程存在争议,在科学不确定的情况下采取任何行动,就失去了伦理学基础。从法律上看,人工干预太阳辐射,即使是科学实验或研究,由于其影响超出了国界,超出了当代人,也超出了人类社会,如果有人采取行动,也存在法律依据上的质疑。人工干预太阳辐射的研究和实施,需要一个国际治理构架。为了防止其他国家单独行动,需要"相互约束"的治理构架——"自我约束"以换取他国同意"自我约束"。鉴于气候变化和光辐管理在科学上的不确定性,目前不宜实施,短期内也不会提上议事日程。太阳光辐管理技术影响的复杂性和气候变化风险的迫切性,需要我们加大科学研究力度,为科学决策提供依据。中国作为一个新兴经济体,世界第一大CO2排放国,地域空间气候条件存在巨大差异性。从减排成本的角度,从气候影响的空间差异性,开展地球工程的科学研究,有着科学、政策和国际气候外交的积极意义。但是,相关的科学研究需要国际制度构架。由于气候变化框架公约及其谈判尚未涉及,需要开展系统科学、技术、经济、法律和国家安全等方面的相关研究,提高科学认知度,为国际谈判和政策选择提供决策依据。     

Transboundary governance of the Curonian Spit World Heritage Site

This study describes the governance and management structures of the Curonian Spit World Heritage Site, a transboundary protected area shared by Lithuania and the Russian Federation. Focusing on the national park authorities it presents the site from a local administrative perspective. The paper shows that due to strong state level influence and a lack of full stakeholder inclusion, different philosophies and priorities on both sides of the border challenge common management efforts and co-operation. Presenting the existing problems the paper points out the need for increased efforts at the state level as well as for the full inclusion of local communities to remove obstacles and foster co-operation. Hence, by adapting to certain environmental and transboundary governance principles, conflicts can be avoided and better results achieved.
