  • 摘要:

    本报告通过梳理环境治理体系中各主体间的关系,从明确各环境主体的责、权、利及定位出发,对照中国和美国在环境治理阶段上的差异,集中于大气、水和土壤三个重点议题,为实现多元共治的环境治理体系提供了分析和建议。

    中国“十三五”环境治理的目标为“改善环境质量”,其前提要“提升环境治理能力,构建政府、企业、社会共治的环境治理体系”,而目前的重点是打好“大气、水、土壤污染防治三大战役”。因此,由政府主导的环境管理转向多元共治的环境治理,是中国环境治理的转型方向。环境治理涉及到立法、行政、司法、企业、环保团体等多元主体,各主体在环境治理中有着各自的责、权、利。明确环境治理各主体的作用和定位,特别是明晰各自的责权利,是构建现代化的环境治理体系的基础。

    通过梳理环境治理体系中各主体间的关系,对照中国和美国在环境治理阶段上的差异,报告将重点集中到中国环境治理关键主体之间的责、权、利复杂多样或不清的三个问题上:

    一是中央与地方关系问题。

    二是政府与企业关系问题。

    三是多元参与环境治理费用的筹集问题

  • 摘要:

    Corrosive groundwater, if untreated, can dissolve lead and other metals from pipes and other components in water distribution systems. Two indicators of potential corrosivity—the Langelier Saturation Index (LSI) and the Potential to Promote Galvanic Corrosion (PPGC)—were used to identify which areas in the United States might be more susceptible to elevated concentrations of metals in household drinking water and which areas might be less susceptible. On the basis of the LSI, about one-third of the samples collected from about 21,000 groundwater sites are classified as potentially corrosive. On the basis of the PPGC, about two-thirds of the samples collected from about 27,000 groundwater sites are classified as moderate PPGC, and about one-tenth as high PPGC. Potentially corrosive groundwater occurs in all 50 states and the District of Columbia.

    National maps have been prepared to identify the occurrence of potentially corrosive groundwater in the 50 states and the District of Columbia. Eleven states and the District of Columbia were classified as having a very high prevalence of potentially corrosive groundwater, 14 states as having a high prevalence of potentially corrosive groundwater, 19 states as having a moderate prevalence of potentially corrosive groundwater, and 6 states as having a low prevalence of potentially corrosive groundwater. These findings have the greatest implication for people dependent on untreated groundwater for drinking water, such as the 44 million people that are self-supplied and depend on domestic wells or springs for their water supply.

  • 摘要:

    The Natural Resource Damage Assessment (NRDA) Trustee Council, the Gulf Coast Ecosystem Restoration Council (RESTORE Council), and the National Fish and Wildlife Foundation (NFWF) are the largest restoration programs working toward the Gulf’s recovery after the 2010 offshore oil spill that led to a 20 percent reduction in commercial fisheries and damaged about 1,100 miles of coastal salt marsh wetlands. These programs administer a majority of the $16 billion available in restoration funds, supporting projects that range from coastal and offshore habitat restoration to recovery of certain species, water quality improvement, and land acquisition.

    The report finds that the majority of past U.S. restoration efforts have not been adequately monitored to assess or improve restoration efficacy. To date, monitoring activities have been dramatically underfunded, and very few programs monitor environmental and social results. To ensure that progress of the efforts can be evaluated, the committee that conducted the study and wrote the report recommended that all restoration activities funded by these programs define specific, measurable objectives and adopt a rigorous statistical monitoring effort and a well-designed data management plan.

    The report also provides more specific restoration monitoring guidelines for six habitats and species groups in the Gulf: oyster reefs, tidal wetlands, seagrasses, birds, sea turtles, and marine mammals. For example, when corrals are constructed to protect sea turtle eggs, their monitoring might entail measuring the amount of beach protected after construction, the location of the corrals relative to the high tide line, and the density of vegetation in the corrals to ensure the project’s success.

    The study was sponsored by the Academies’ Gulf Research Program, which was established at the request of the U.S. government as part of legal settlements in the aftermath of the Deepwater Horizon oil spill. The National Academies of Sciences, Engineering, and Medicine are private, nonprofit institutions that provide independent, objective analysis and advice to the nation to solve complex problems and inform public policy decisions related to science, technology, and medicine. They operate under an 1863 congressional charter to the National Academy of Sciences, signed by President Lincoln. For more information, visit http://national-academies.org.

  • 摘要:

    Over the past 10 years, UNEP has endeavoured to identify and highlight emerging issues of global concern through the UNEP Year Book series. This new UNEP Frontiers report advances this work, signalling environmental issues and solutions for effective and timely responses. Some issues may emerge as a result of new scientific findings and understanding of interactions between environmental, social and economic systems; others may be persistent issues for which new approaches and technologies have emerged to equip decision-makers and managers with more practical solutions and tools. Some issues may be local, relatively small-scale issues today, with a potential to become an issue of regional or global concern if not addressed early.

    The UNEP Frontiers 2016 edition presents six emerging issues. It highlights, for example, that the global significance of the financial sector should not confine itself only to enhancing global economic growth, but also to advancing environmental sustainability. The financial sector has a crucial role to play in investing in new low-carbon, resource efficient and environmentally sound assets, and shifting capital away from traditional assets that have high impacts on the environment. The report presents a number of emerging financial initiatives led by the financial sector as innovative solutions to sustainability challenges.

    The UNEP Frontiers report also highlights two critical issues associated with climate change. The issue of loss and damage to ecosystems due to changing climate has risen to global attention in recent years, and has led to the establishment of the Warsaw international mechanism for loss and damage associated with climate change impacts. The report introduces a number of case

    studies on recent sudden- and slow-onset events that have caused losses and damages to ecosystems and human systems, and presents a range of risk management tools needed to avoid harm.

  • 摘要:

    The publication is the result of a new effort on portfolio review in the GEF Secretariat. This effort is intended to promote learning and knowledge synthesis from GEF projects under implementation. This particular portfolio review was focused on projects designed to combat land degradation through application of integrated approaches. It was financed under the two operational programs that preceded the current Land Degradation focal area: Integrated Ecosystem Management (OP 12) and Sustainable Land Management (OP 15). The emphasis was on understanding the catalytic nature of GEF financing to advance integrated approaches in countries affected by land degradation, including processes, practices, tools, and knowledge innovations that were embodied in the projects.
