Effective policies to slow the rate of anthropogenic biodiversity loss should reduce socioeconomic pressures on biodiversity, either directly or by modifying their underlying socioeconomic driving forces. The design of such policies is currently hampered by the limited understanding of socioeconomic drivers of and pressures on biodiversity as well as by lacking data, indicators and models. In order to improve understanding of these issues we here propose a conceptual model of socioeconomic biodiversity drivers and pressures. The model is based on the drivers-pressures-impacts-states-responses (DPSIR) scheme and on the socioeconomic metabolism approach. The aim of the model is to guide research aimed at improving our understanding of socioeconomic biodiversity pressures and drivers and to serve as a basis for the development of formal, quantitative models in that field. Based on three European long-term socio-ecological research (LTSER) platforms, we analyze the model's applicability and suitability as well as data availability and research needs. These platforms are the Danube Delta Wetland System in Romania, the Doñana in Spain and the Eisenwurzen in Austria. An empirical analysis of the relationship between the human appropriation of net primary production (HANPP) and breeding bird richness in the Eisenwurzen demonstrates the ability of HANPP to provide a link between socioeconomic pressures/drivers and biodiversity. The analysis of the case studies underlines the potential utility of the conceptual model to guide future research into socioeconomic biodiversity drivers and pressures. However, considerable investments in monitoring and reconstruction of past trajectories as well as in model development will be required before mathematical (computer) models of the interrelation processes between society and ecosystems can be successfully deployed.  相似文献

The current biodiversity loss is dramatic. Over the past 50 years, more than 68% of the mammals, birds, amphibians, reptiles, and fish on Earth have disappeared, putting the planet's survival and its inhabitants—including human beings—at risk. Financialization, or the transformation of nature into financial assets, is increasingly proposed as a solution to the biodiversity crisis. Proponents of financialization believe that assigning a monetary value to nature will incentivize human beings to protect habitats and their species. This article offers a four-mechanism model of nature's financialization, explaining why it is virtually impossible to financialize nature. We collected data through a unique two-stage data collection process, including a single case study and additional interviews with conservationists and conservation finance specialists. We analyzed the development of a calculative device, the “Index,” designed to assess the impact of conservation efforts on the survival of endangered species. Conservationists hoped to use the Index to calculate the financial return of a conservation impact bond, a financial instrument designed to finance conservation projects. However, they did not achieve their goal. We discuss the implications for the financialization and conservation literature and the role of accounting therein. We notably question previous accounts of financialization, including the need for financial numbers or financial actors. We ultimately show that a financialization project can transform practices toward financialization, even if the financialization process is not complete.  相似文献

Targeting Incentives to Reduce Habitat Fragmentation   总被引:2,自引:0,他引:2  
This article develops a theoretical model to analyze the spatial targeting of incentives for the restoration of forested landscapes when wildlife habitat can be enhanced by reducing fragmentation. The key theoretical result is that the marginal net benefits of increasing forest can be convex, in which case corner solutions—converting either none or all of the agricultural land in a section to forest—may be optimal. Corner solutions are directly linked to the spatial process determining habitat benefits and the regulator's incomplete information regarding landowner opportunity costs. We present findings from large-scale empirical landscape simulations that support our key theoretical results.  相似文献

This article evaluates the cost‐effectiveness of the Catchment Care Australian conservation auction. It provides evidence of auction cost effectiveness, and estimates cost savings from two discrete components: (i) the opportunity cost revelation incentive provided by the auction mechanism, and (ii) the improved environmental targeting capacity that results from development of a scientifically based environmental benefits assessment capacity. Results show that there are potentially very large returns associated with the latter component that have been overlooked in the literature. Additionally, transaction costs involved with administering the case study conservation auction and the prior non‐auction payment policy are compared. We find that the administration costs for the auction were greater than or equal to those associated with the prior policy. Estimates of relative cost effectiveness across policies are shown to be sensitive to the methods of comparison. In this case study, there is inelastic supply of the last units of environmental benefit. This inelasticity results in large estimated auction comparative cost advantage when the benefit metric is the estimated cost required to achieve auction aggregate environmental benefit. Estimated benefit of the auction is much less when measured as environmental benefits attainable with alternative payment policies subject to the auction budget constraint.  相似文献

森林生物多样性评价模型的改进   总被引:3,自引:0,他引:3  
针对2002年的评价模型中的不足,提出了新的改进后的森林生物多样性变化的评价模型,并在我国第六次森林资源清查(1999~2003)资料的基础上,对1973~2003年我国森林生物多样性的变化进行了补充评价。评价结果表明:我国森林生物多样性的压力越来越大,压力指数由1973年的100,上升到2003年的199.10,上升了1.99倍;森林物种多样性总体的下降趋势已有一定幅度的改变,森林物种多样性指数增加了31.12%。森林生态系统多样性和森林生物多样性先逐渐上升,尔后又下降,第六次森林资源清查时又有所恢复,并分别上升了4.67个百分点和17.90个百分点。  相似文献

This study of the community's acceptance of biodiversity offsets in Australia provides insights relevant to future revisions of offset policies of both State and Commonwealth Governments. A choice experiment was used to measure preferences for the general acceptability of offsetting, and for a number of attributes that define how an offset can be implemented. Based on a sample of 204 respondents from Perth, WA, we found that the majority of respondents did not object to the practice of biodiversity offsetting in general. A minority of respondents preferred that offset actions be direct, but most accepted a combination of direct and indirect actions. Individuals generally preferred that the offset be located near the site of impact, and it became more unacceptable the further away that it was located. However, there was heterogeneity in preferences for protecting the impacted species or a more endangered one.  相似文献

The aim of this research is to understand the complex and relatively understudied relationship between human and behavioral factors and low-carbon management practices from the perspective of the resource-based view (RBV). Research application is in the “biodiversity sector” and consists of a survey and multiple-case study in Brazil, the richest country globally in terms of biodiversity but a country that also faces challenges in protecting biodiversity. The research problem considers the relationship between human critical success factors and the adoption of low-carbon management practices. Quantitative analysis through structural equation modeling shows the three branches of hypothesis to be accepted—the first with a higher coefficient than the second and the second with a higher coefficient than the third. It was observed that human factors influence low-carbon product management practices the most, followed by process practices and finally logistics practices. Qualitative multiple-case study research shows that companies are at different stages of maturity in relation to low-carbon management organizational practices, ranging from the highest stage to the lowest. It was found that the intensity of the presence of human critical success factors was higher where organizations had greater adoption of low-carbon management practices.  相似文献

This paper presents an empirical examination of the role of employee involvement in the internalization of corporate biodiversity management. A qualitative study in natural resource companies was conducted, based on semi‐directive interviews with managers, consultants, and experts in this area. The findings show that employee involvement is essential to improve biodiversity practices in natural resource companies, which largely rely on organizational citizenship behaviors for the environment. The role of tacit knowledge, voluntary initiatives, and prevention of harmful behaviors in the workplace are highlighted. The main obstacles to the internalization of biodiversity issues include their complexity, the lack of corporate commitment, the externalization of initiatives, and the lack of training for employees. The contributions to the literature on corporate environmental management, internalization of new practices, and organizational citizenship behaviors for the environment are explained. Managerial implications and avenues for future research are also provided.  相似文献
