Framework for the environmental impact assessment of operational shipping

Shipping is an important source of pollution affecting both atmospheric and aquatic environments. To allow for efficient mitigation of environmental degradation, it is essential to know the extent of the impacts of shipping in relation to other sources of pollution. Here, we give a perspective on a holistic approach to studies of the environmental impacts of operational shipping through presentation of an assessment framework developed and applied on a case of shipping in the Baltic Sea. Through transfer of knowledge and concepts, previously used in assessments of air pollution, now applied to assessments of marine pollution and underwater noise, the horizon of understanding of shipping-related impacts is significantly improved. It identifies the main areas of environmental degradation caused by shipping and potential improvements through legislation and technological development. However, as the vast majority of contaminants discharged into the sea are not routinely monitored and assessed, the links between pressure of contaminants from shipping and environmental state and impacts will not be caught in the current environmental regulatory frameworks.     

地震灾后重建规划环境影响评价特点和实施框架初探

5．12汶川特大地震灾害引起了社会和学术界对地震灾后重建规划广泛的关注。地震灾后重建规划几乎包含了当前规划领域中的所有挑战,是速度和质量兼顾、人性与理性权衡、社会经济与环境效益统一、多方博弈的过程,对灾后重建规划环评也从理论到实践层面提出了新的挑战。本文在对灾后重建规划特点进行归纳的基础上提出灾后重建规划环评相应具备的特点,即早期介入、与规划过程融合、增加灾害情景、突出规划协调性分析和应用反规划思路等特点,并进一步以《国家汶川地震灾后重建总体规划》为例说明了与灾后规划融合的环评流程、灾后规划环评的关键内容和评价思路。在对常用规划环评方法从信息成本、工作成本、客观和量化程度等原则进行评价后认为灾后重建规划环境评价中应有效利用比较评价法、GIS叠图法、生态承载力评价法等相对快捷、成熟或客观的方法。     

中国绿色经济战略研究

以联合国"里约+20"会议为背景,在梳理世界主要国家绿色经济发展进程、绿色经济理论研究和实践探索,分析当前绿色经济发展现状和政策的基础上,探讨了我国绿色经济发展战略框架问题。认为:政府层面要加强对绿色产业发展引导、努力完善激励约束政策,保障绿色经济的稳健发展,重视绿色科技人才队伍建设,增强绿色产业自主创新能力。目前要解决的问题,一是通过建立排污权交易市场,实现环境价值的货币化;二是建立健全与绿色经济核算相关的法规制度;三是实施绿色GDP考核制度,从根本上改变经济增长方式。企业层面要重视绿色科技人才队伍建设,增强绿色产业自主创新能力,实现绿色产业的发展与调整。行业层面要着重节能建筑、可再生能源、可持续交通、可持续农业和生态基础设施建设等。消费者层面要加强绿色理念宣传,积极倡导绿色消费。从国际贸易的角度,应积极争取发达国家提供技术支持和技术培训,以帮助环保商品和服务行业的发展。     

Toward an improved legislative framework for China's land degradation control

The Chinese government has recently been attaching increasing importance to the application of effective legal tools to tackle land degradation (LD) issues. Based on the concept of sustainable development, China began developing and reaping the benefits of environmental and natural resources legislation including LD control regulations in the 1990s. In the past three years, some central‐western provinces in China have been implementing a “ People's Republic of China/Global Environment Facility (PRC/GEF ) Partnership on LD Control of Dryland Ecosystems”, which is based on an integrated ecosystem management (IEM) approach. IEM is designed to achieve a balanced, scientific and participatory approach to natural resources management, which creates the potential to improve the quality of Chinese environmental law and policy procedures. The paper studies the existing Chinese national laws and regulations pertinent to LD control within 9 areas covering land, desertification, soil erosion, grassland, forest, water, agriculture, wild animals and plants, and environment protection in detail, against IEM principles and basic legal elements. The main objective is to identify problems and provide feasible solutions and recommendations for the improvement of the existing laws and regulations. The authors conclude that the development of an improved national legislative framework is essential if LD control is to be successfully achieved. The paper is partly based on Component 1 — Improving Policies, Laws and Regulations for Land Degradation Control under PRC/GEF Partnership on Land Degradation in Dryland Ecosystems (TA 4357).

River basin governance enabling pathways for sustainable management: A comparative study between Australia,Brazil, China and France

Successful river basin governance is challenged by actor engagement in the various stages of planning and management. A governance approach for determining priorities for actors for sustainable management was developed, based on a river basin diagnostic framework consisting of four social-institutional and four biophysical indicators. It was applied in river basins in Australia, Brazil, China and France. Actors diagnosed current and target capacity for these indicators, and estimated synergistic influences of interacting indicators. The results reveal different priorities and transformative pathways to achieve basin plan outcomes, specific to each basin and actor groups. Priorities include biodiversity for the Murray-Darling, local water management needs for the São Francisco and Yellow rivers, and improved decision-making for the Adour-Garonne. This novel approach challenges entrenched views about key issues and actor engagement roles in co-implementation of the basin plan under existing prevailing governance models, with implications for engagement and international collaboration on basin governance.Supplementary InformationThe online version contains supplementary material available at 10.1007/s13280-021-01699-4.
