Abstract

A recent focus of ecosystem services research has been on the definition of biophysical outcomes and measures most closely linked to social welfare. There is a particular need to identify biophysical outcomes corresponding to existence values. (Values associated with existence apart from any current or future use). We review economic and ecological evidence to answer two key questions: First, what are ideal characteristics of linking indicators for existence values? Linking indicators should be: understandable, subject to direct sensory perception, represented at relevant temporal and spatial scales, comprehensive, and quantifiable in a repeatable manner. Second, what types of ecosystem outcomes are most likely to be associated with these values? We distinguish between indicators of taxa and ecological landscapes, and then multiple subcategories within each. Our fundamental conclusion is that while there are general principles informing the specification of linking indicators of existence values, there is no compact set of indicators or measures that applies universally. The case-specific nature of these issues-general guidelines notwithstanding-implies the need for sustained partnerships between social and biophysical scientists to address questions of indicator choice.

支持分析和交流存在价值的生物物理措施。
生态系统服务研究最近的一个重点是定义与社会福利最密切相关的生物物理成果和措施。特别需要确定与存在价值相对应的生物物理成果。(与当前或未来使用之外的存在相关的价值)。我们回顾了经济和生态证据,以回答两个关键问题:首先,存在价值的关联指标有哪些理想特征?关联指标应:可理解、可直接感知、在相关的时间和空间尺度上体现、全面且可重复量化。其次,哪些类型的生态系统结果最有可能与这些价值相关联?我们区分了类群指标和生态景观指标,然后在每种指标中又区分了多个子类别。我们的基本结论是,虽然存在价值关联指标的规范有一般原则可循,但没有一套放之四海而皆准的紧凑型指标或衡量标准。这些问题的具体情况具体分析--尽管有一般性的指导原则--表明社会和生物物理科学家之间需要建立持续的合作关系,以解决指标选择问题。

期刊介绍: Environmental and resource economics has become a broad topic making connections with many other subdisciplines in economics as well as the natural and physical sciences. It has also experience a significant growth in research such that the literature is exploding in terms of the number of topics addressed, the number of methodological approaches being applied and the sheer number of articles being written. Coupled with the high degree of specialization that characterizes modern academic research, this proliferation of topics and methodologies makes it impossible for anyone, even those who specialize in the subject, to keep up with developments in the field.
