构建生态环境技术服务体系的基本定位与主要对策

四个方面的情况表明,我国必须高度重视生态环境技术服务体系建设问题:一是随着污染防治攻坚战在向纵深推进过程中,地方政府"不会管"、企业"不会治"的问题比较普遍,且日益突出;二是目前各级生态环境部门,特别是市、县两级生态环境技术支持力量薄弱、专业化能力不足,难以支撑当地政府和企业治理环境污染的技术需求;三是目前的生态环境技术服务市场尚满足不了实际需求;四是无论是从结构还是从作用看,生态环境技术服务体系已成为生态环境治理体系和治理能力的短板。因此,构建生态环境技术服务体系是推进生态环境治理体系和治理能力现代化的重要内容,其作用是,在要求环境责任主体做什么的同时,帮助和指导他们怎么做,解决"不会管"和"不会治"的问题。现阶段,政府推动构建生态环境技术服务体系的重点任务:一是明确职能,系统谋划,做好顶层设计;二是强化相关能力建设;三是建立和完善生态环境标准和重大规划与行动计划的配套技术方案制度;四是培育、壮大和规范生态环境技术服务市场;五是以生态环境科技成果转化为抓手,牵引技术服务体系建设。     

Beyond accountability: alternative rationales for transparency in global trade politics

ABSTRACT

The conventional view of transparency is that it is a critical tool to combat corruption and ensure the democratic accountability of government. This article argues that the negotiation of mega-regional trade agreements (RTAs) and their content indicates the need distinguish different types of transparency. Trade activists that call for drafts of the text of a mega-RTA to be released while negotiations are ongoing are seeking deliberative transparency, which provides opportunities for meaningful public participation and consultation. The trade advisory systems that could provide opportunities for deliberation instead deliver technocratic transparency; the rationale is to increase the effectiveness of mega-RTAs rather than their democratic legitimacy. Frequent leaks of draft chapters of mega-RTAs provide opportunities for deliberation, but some actors involved in leaking are engaged in disruptive transparency where the aim is to complicate trade negotiations, making a final deal less likely. While these varieties of transparency emerge in the context of the negotiating process, disciplinary transparency – which often becomes a regulatory tool for multinational corporations to influence policy-making – is found in the text of mega-RTAs. Certain forms of transparency increase the likelihood that mega-RTAs will be compatible with strong environmental policy, while others may have a detrimental impact.     

Transparency in global sustainability governance: to what effect?

ABSTRACT

Transparency in environmental governance is no longer an uncontroversial answer to problems of accountability and effectiveness. How to design effective transparency systems and in what policy contexts they are effective remain contested issues. This special section, consisting of this introduction and four research articles, interrogates complex and potentially conflicting links between transparency, accountability, empowerment and effectiveness in environmental governance. Building on existing literature and the four contributions, we discuss persisting diversity in varieties of transparency, the evolving dynamics of commodity chain transparency, and the consequences of emerging novel forms of digitalized transparency. As we show, the contributions to this special section interrogate in novel ways the transformative potential of transparency, through shedding light on the performative effects of transparency in ever more complex environmental governance contexts. These contexts may include, inter alia, the growing ubiquity of traceability in transnational commodity chains, the need for ever more anticipatory (ex-ante) forms of environmental governance, and an ever-broadening quest for digitally monitored environments. In particular, the impacts of the real-time ‘radical’ transparency engendered by use of novel digital technologies remain under-analyzed in the sustainability domain. We conclude by raising several critical concerns that deserve further scientific research and policy debate.     

Diversifying forest expertise: forest journals narrating policy change

ABSTRACT

During policy change, the role of the actors communicating the change to different audiences is accentuated. The media plays an increasing role, either as an actor or by providing a stage for other actors. In particular, specialised journals represent an influential, albeit understudied, sphere of policy studies. We use the narrative policy framework complemented with frame analysis to trace how specialised media can affect policy implementation through implicit suggestions for action. Using this combined approach, we analyse how specialised forest journals, which are the most important forest information source for Finnish forest owners, have conveyed the renewal of forest legislation in Finland. The core message of the journals is that forest owners should, despite their new freedom granted by the reform, rely on experts rather than experimenting when managing their forests. This suggests that the media contributes to a path-dependent continuation of a forest policy that is based on a rationalistic exploitation ethos. The innovative potential, which the policy change aimed at encouraging, is thereby partially undermined. However, the analysis of the narratives also reveals that forest expertise and professionalism are diversifying. This notion is important as diversity can eventually lead to narratives supporting more fundamental change in forests management.     

Realising local food policies: a comparison between Toronto and the Brussels-Capital Region’s stories through the lenses of reflexivity and co-learning

ABSTRACT

This paper revisits the development of Toronto and Brussels’ local food policies by analysing reflexivity and co-learning as important dimensions within a Hybrid Governance Approach (HGA); it approaches the interaction between four forms of governance (bottom-up, networked, state, market-led) and the tensions between them as hybrid dynamics. Within this approach, reflexivity refers to the positionality of agents, i.e. to the ways local food actors embody as well as reflect on and reconsider their principles and practices through time. Closely related to reflexivity, co-learning involves agential interactions to co-construct enabling food policy delivery systems. The HGA is mobilised to understand the ways in which reflexive capacities, as well as co-learning, take place in the two cases and how they lay the basis of particular modes of (de)institutionalisation. Learning from the two cases’ trajectories, this paper highlights: (a) the role of key governance tensions as triggers as well as breeding grounds for reflexivity and co-learning outcomes; (b) the challenges of food movement actors to surmount or valorise key tensions in order to build accountable modes of food policy delivery through time; (c) the struggles to build legitimacy and accountability in local food movements through the development of bottom-linked organisations and governance modes.     

A LAND-USE POLICY BASED ON WATER SUPPLY1

ABSTRACT: Santa Fe Country, New Mexico, has adopted a land-use policy in which zoning densities provide a balance between the water use on a parcel of land and the water supply available bencath that land. In two of four mapped hydrologic zones, ground water in storage will be allowed to be mined to exhaustion in 100 years (40 years in urban areas). Elsewhere, the policy is for a steady state with use balanced by recharge. Equations to determine storage or recharge can be solved using site specific data or regional estimates of hydrologic conditions. Substantial reductions in the lot size requirements are allowed if water conservation convenants are adopted. Public acceptance indicates that the policy successfully integrates technical and political concerns. It is simple to administer, yet reflects widely expressed public goals and values.     

UNIVERSITY WATER RESOURCES RESEARCH AND STATE LEGISLATURES1

ABSTRACT: Societal trends indicate an increased need for university water researchers to develop and improve working relationships with state legislatures to help ensure that water related legislation is based on sound water resources information. Recommendations for providing technical support to state legislatures on water resources issues include: the necessity for researchers to take the initiative; the importance of researchers capitalizing on existing linkages; the need to maintain a continuous link between key legislators, legislative staff, and researchers; and the need for researchers to provide comprehensible information in a timely manner.     

EMERGING STATE ROLES IN URBAN STORMWATER MANAGEMENT1

ABSTRACT: The technology of urban stormwater management has far outpaced its actual application in new urban development. This article documents that implementation gap, but shows that state and local governmental measures, particularly storm drainage regulations, can lead to improved performance in the private sector. Although state stormwater management programs are in their infancy, they are already having a measurable effect in stimulating the adoption of local governmental programs to manage urban storm water. Pioneering state programs in Maryland, New Jersey, and Pennsylvania, described in this article, provide models for states contemplating the formulation of stormwater management programs.     

基于ZSI岩溶溶洞对基坑开挖的影响

为了研究大连多岩溶区的复杂地质条件对基坑开挖的影响,运用有限差分软件FLAC3D对不同溶洞位置的基坑进行模拟,得到位移变化规律。同时利用单元安全状态评价指标ZSI(Zone State Index)对不同溶洞位置下基坑周围土体进行评价,针对影响较大区域溶洞提出合理的溶洞处理方案。研究结果表明:溶洞对基坑稳定性影响程度由大到小依次是被动区、过渡区、主动区。针对被动区溶洞采取开挖前注浆处理,通过对大连地区深基坑进行数值模拟确定的不同溶洞位置对基坑影响程度具有一定的指导意义,可为岩溶地区深基坑工程的设计与施工提供参考。
