This paper discusses common organizational problems that cause inadequate planning and implementation processes of endangered
species recovery across biologically dissimilar species. If these problems occur, even proven biological conservation techniques
are jeopardized. We propose a solution that requires accountability in all phases of the restoration process and is based
on cooperative input among government agencies, nongovernmental conservation organizations, and the academic community. The
first step is formation of a task-oriented recovery team that integrates the best expertise into the planning process. This
interdisciplinary team should be composed of people whose skills directly address issues critical for recovery. Once goals
and procedures are established, the responsible agency (for example, in the United States, the US Fish and Wildlife Service)
could divest some or all of its obligation for implementing the plan, yet still maintain oversight by holding implementing
entities contractually accountable. Regular, periodic outside review and public documentation of the recovery team, lead agency,
and the accomplishments of implementing bodies would permit evaluation necessary to improve performance. Increased cooperation
among agency and nongovernmental organizations provided by this model promises a more efficient use of limited resources toward
the conservation of biodiversity. 相似文献

The challenge of making central requirements work at local levels is a common problem for environmental governance throughout
the world. Countries can learn from one another's approaches, but must understand the local context in which they are set.
This paper compares the features of the China and US environmental governance systems that need be understood by those working
between the systems. Key features include: (1) common values which shape the environmental governance choices in both countries,
but which may have different practical meanings in each country; (2) America's common law-based environmental governance system,
and China's civil law system, which involves plan(s) as well as law; (3) America's Federal central-local system, and China's
unitary central local system. This paper concludes by suggesting areas in which further comparative understanding may be of
value, including: (1) better understanding of the role of plan and law in China's governance system; (2) comparing the American
Federal-state agreement system for implementation of environmental law with the China central-local system of target responsibility
agreements for plan implementation; (3) improving understanding of nongovernmental resources needed to assure compliance with
environmental laws and plans; (4) identifying institutions that can coordinate central-local and cross-border environmental
governance. 相似文献

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. 相似文献

风险评价在规划环境影响评价中的应用 总被引:1,自引:0,他引:1
规划环境影响评价(以下简称规划环评)是对规划实施后可能造成的影响进行分析、预测和评价的过程,属于战略影响评价范畴,需要解决区域内项目布局、规模等问题.规划环评中的风险评价应同规划环评的目标相对应,即从源头上对规划中涉及的风险源进行分析并提出预防或减缓风险的方案.比较了规划环评风险评价和建设项目风险评价后指出,规划环评中风险评价的目标主要在于通过对风险源的识别和分析,为整个区域内项目的布局、规模以及土地利用提供合理指导,并对原规划方案进行反馈.总结了风险评价用于规划环评中的特点及其与建设项目风险评价在步骤上的异同,并以平顶山化工城规划环境影响评价中风险评价的内容为例,对风险评价在规划环评中的应用进行了探讨.结果表明,平顶山的风险源对周围地区有一定影响,应考虑部分地区的搬迁工作. 相似文献
