论我国海岸带立法的核心内容

2018年11月18日发布的《中共中央国务院关于建立更加有效的区域协调发展新机制的意见》明确提出了"推动海岸带管理立法"的工作要求。该工作的重心理应是解决目前我国海岸带管理实践中的突出问题，即陆海之间、部门行业之间和行政辖区之间难以统筹协调的问题。解决该问题的有效途径是通过立法的方式构建统筹协调机制。美国海岸带管理制度中的统筹协调机制颇具特色，由"总协调人"和"联络人"制度、"联邦一致性"制度、州海岸带管理项目与州其他项目的统筹协调制度，以及陆海统筹协调制度等方面组成。我国可以借鉴其成功经验，在海岸带立法中，以构建统筹协调机制为核心内容。该机制以程序性规则为主体，设立"总协调人"和"联络人"制度，组成统筹协调网络，并规定统筹协调的基本"排序规则"。

Utilitarian framings of biodiversity shape environmental impact assessment in development cooperation

Biodiversity is under threat from anthropogenic pressures, in particular in biodiversity-rich developing countries. Development cooperation actors, who traditionally focus on the improvement of socio-economic conditions in the South, are increasingly acknowledging the linkages between poverty and biodiversity, e.g. by referring to the ecosystem services framework. However, there are many different framings which stress the need for biodiversity integration and which influence how biodiversity and development are and/or should be linked. Moreover, there is a gap between the lip service paid to biodiversity integration and the reality of development cooperation interventions. This study analyses how biodiversity framings are reflected in environmental impact assessment (EIA) practice, and how these framings influence EIA and decision-making. The findings, based on an in-depth qualitative analysis of World Bank EIAs undertaken in West Africa, indicate the incoherent quality but also the dominance of the ‘utilitarian’ and ‘corrective’ framings, which respectively stress human use of nature and mitigation of negative unintended development impacts. Identifying and highlighting these discursive trends leads to increased awareness of the importance of biodiversity among all development actors in North and South. However, some framings may lead to an overly narrow human-centred approach which downplays the intrinsic value of biodiversity. This study proposes recommendations for an improved integration of biodiversity in development cooperation, including the need for more systematic baseline studies in EIAs.     

Coalition formation in fisheries with potential regime shift

A system can undergo rapid regime shift in which the growth of natural resources suddenly and permanently declines. We examine how the threat of such a shift alters the strategic management of a common pool renewable resource. We consider exogenous and endogenous threats and examine their effects on both incentives to join a coalition and harvest decisions. We find that an exogenous threat of reduced resource growth may cause the coalition to grow in size, and, perhaps of most interest, we identify conditions under which members of the stable coalition reduce harvest while non-members increase harvest in response to the threat. In contrast, an exogenous threat of total stock collapse may destabilize coalitions, resulting in higher harvest from former members, but reduced harvest by non-members. When the threat of either type of shift is endogenous, the threat of regime shift can induce stable coalitions with more than two members. In particular, we identify cases in which the first best (full cooperation) is sustained as an equilibrium outcome. Finally, we find that the relation between the magnitude of the shift and the size of stable coalitions may be negative.     

混合菌种在发酵法生物产氢中的协同作用

为探讨产氢发酵细菌混合培养时菌种间的协同作用,本研究在间歇试验条件下,分别考察以葡萄糖和复杂有机物(淀粉、牛肉膏、聚乙二醇乙二酸酯和胰蛋白胨)为底物时,5株HPB(B49、H1、LM12、LM11和B51)混合培养,高效HPB(B49)与3株非产氢发酵细菌(L10、拟3-2和芽孢1)分别混合培养,以及B49与活性污泥混合培养对产氢能力的影响.试验结果表明,混合菌种间协同作用发挥是有条件的.当利用葡萄糖发酵产氢时,菌种间对共同底物的竞争使其协同作用无法发挥,从而制约了高效产氢细菌(HPB)的产氢能力;而利用复杂有机物发酵产氯时,菌种间的协同作用得以发挥,并促进了高效HPB产氢能力的提高.同时提出,针对不同底物可以采用不同的培养方式.     

An adapted companion modelling approach for enhancing multi-stakeholder cooperation in complex river basins

The sustainable development agenda 2030 calls for achievement of certain targets to ensure access to water and sanitation for all. Multi-stakeholder partnerships and the use of data and modelling tools are conditioning elements for their achievement. In this article, we demonstrate that participatory modelling supports informed and participatory decision making in complex river basins. An adapted companion modelling approach is presented to support collective action by reducing disputes and enhancing collaboration among stakeholders. The co-development and use of empirical models for understanding the complexity of the physical system is combined with the use of role-playing games to ensure the active involvement of stakeholders. The approach is implemented in a top-down water quality planning process in Turkey. Results show its suitability for managing water quality in complex river basins in an inclusive manner and its substantial benefits in developing stakeholders’ capacities and creating a cooperative environment.

生态环境多中心治理路径探析

生态环境是人类赖以生产和生活不可或缺的一部分,生态资源的开发和使用促进了人类社会的发展,然而伴随人类的开发和使用,生态环境消耗已经超出其自身恢复能力,生态环境治理成为世界各国不容忽视的重要问题。我国生态环境治理取得了一定成果,但总体而言生态环境恶化趋势并未改变,探索生态环境多中心治理路径十分必要。本文从我国生态环境治理现状出发,阐述了以市场为中心和以政府为中心两种传统生态环境治理模式及其局限性,并在此基础上提出构建生态环境多中心治理模式,探析生态环境多中心治理路径。     

跨境水资源分配典型模式特征评述及中国主张思考

跨境河流治理的核心是跨境水资源分配问题。结合案例分析,从流域国利益关系视角概括出四种跨境水资源分配典型模式——“强权”模式、“传承”模式、“绅士”模式和“共享”模式,并从适用条件、磋商履约、运行效率和潜在问题等方面进行特征评述。对跨境河流水资源分配的中国主张提出如下建议：拒绝“强权”模式,依托“一带一路”走出“水霸权”话语困境;主张“共享”模式,倡导构建跨境水资源“命运共同体”;对水资源相对丰沛的跨境流域,主张创新特殊水情下的跨境水资源调控机制;对水资源相对稀缺的跨境流域,通过实施虚拟水贸易战略促进“共享”;排除外界干扰,主张建立独立、权威的跨境水资源协调机构。
