1. Introduction Development of human industrial civilization and predatory exploitation of natural resources have in- duced tremendous changes of ecological environment. In recent years, territorial and global environmental problems have increased, such as greenhouse effect, depletion of ozone, global warming, water scarcity, water pollution, acid rain, decrease of biodiversity, soil erosion desertification etc. These changes seriously intimidate the health and security of ecosystems, and dist… 相似文献

A call has been made for conservation planners to include ecosystem services into their assessments of conservation priority areas. The need to develop an integrated approach to meeting different conservation objectives and a shift in focus towards human wellbeing are some of the motivations behind this call. There is currently no widely accepted approach to planning for ecosystem services. This study contributes towards the development of this approach through a review of conservation assessments and the extent to which they include ecosystem services. Of the 476 conservation assessments identified by a set of search terms on the Web of Science, 100 were randomly selected for this review. Of these only seven had included ecosystem services, while another 13 had referred to ecosystem services as a rationale for conservation without including them in the assessment. The majority of assessments were based on biodiversity pattern data while 19 used data on ecological processes. A total of 11 of these 19 assessments used processes, which could be linked to services. Ecosystem services have witnessed an increase in attention received in conservation assessments since the year 2000, however trends were not apparent beyond this date. In order to assess which types of ecosystem services and how they have been accounted for in conservation assessments, we extended our review to include an additional nine conservation assessments which included ecosystem services. The majority included cultural ecosystem services, followed by regulatory, provisioning and supporting services respectively. We conclude with an analysis of the constraints and opportunities for the integration of ecosystem services into conservation assessments and highlight the urgent need for an appropriate framework for planning for ecosystem services. 相似文献

This paper is about stability and change in the policy-making discourse of a traditional neoclassical policy area, the area of car taxation. Stability is here related to the unquestioned continuation of a traditional neoclassical economics perspective in policy-making, whereas change is related to the introduction and impact of environmental concerns. The aim of the paper is to investigate, what makes green discourses matter in traditional policy-making. It is based on an in-depth study of policy-making processes related to car taxation in two environmental front-runner countries, Sweden and Denmark.Making green discourses matter in policy-making is an important contemporary environmental challenge. Therefore, as Tian Shi argues, we need more research into the institutional setting of the policy-making process. Ecological economics as a policy science has to have a broad understanding of the political economic nature of the policy process. Taking this standpoint as the point of departure, the paper seeks to uncover questions such as, what is the policy-making reality in which Swedish and Danish green discourses have to make a difference? How do existing neoclassical regimes react, when green actors attempt to influence policy-making from an environmental point of view? And to what extent can green discourses actually have an impact on the policy world within the area of car taxation?The paper concludes that the traditional neoclassical economic discourse is particularly robust and resistant against alternative green discourses. Stability rather than change is the dominating picture. This does not imply that environmental concerns will not be taken into account in the future. Rather it implies that only the changes, which keep up the existing order, or enhance the narrow power-related interests of the dominating actors, will materialise more or less easily. The rest is a power struggle in which timing, coalition-building, persistence and thorough knowledge about the field in question is of importance. In this struggle change agents will also benefit from the ability to rethink dominating ways of thinking and doing in an environmentally benign way. A rethinking that is based on environmental values while at the same time holding positive visions that are ‘compatible’ with the existing dominating discourse. 相似文献

Willingness to take on risk is influenced by the presence of fair and unfair background risks for decision makers who are risk vulnerable as defined by Gollier and Pratt [1996], for these decision makers are more risk averse when they possess such an uninsurable background risk. We present an alternative derivation of the index of local vulnerability based on Diamond and Stiglitz [1974] compensated increases in risk, such that risk aversion increases with the introduction of any small fair background risk if and only if the index of local vulnerability is positive. We establish that the increase in risk aversion is greater for those who are more vulnerable as measured by the index of local vulnerability. 相似文献
