The Case for Diminishing Marginal Existence Values 总被引:3,自引:0,他引:3
Kimberly Rollins Audrey Lyke Database Analyst 《Journal of Environmental Economics and Management》1998,36(3):324-344
This study addresses the debate over sensitivity of existence values measured by contingent valuation to scope tests. We reconcile much of the debate within one theoretical model. If marginal WTP for existence goods is diminishing, then a study that tested for sensitivity to scope over a range for which marginal WTP is high would be more likely to detect sensitivity to scope than a study that focused on a range for which marginal WTP is much lower. An empirical model demonstrates this point for existence value of remote wilderness parks. These results have significant implications for future contingent valuation work. 相似文献

Developing countries are often most impacted by climate change. While the work of international environmental organizations has received considerable public and academic attention, local environmental non-governmental organizations (ENGOs) also play a key role in assisting local populations adapt to the changing environment and develop in a sustainable manner. Drawing on data from semi-structured interviews with rural Malians, and using a local ENGO [the Mali-Folkecenter Nyetaa (MFC)] as a case study, this paper begins by describing how rural Malians perceive climate change is impacting their lives, and how the MFC attempts to address these impacts with their programs in the communities. The paper then illustrates the unique advantages of local ENGOs, both in their holistic approach and their integration in the communities, to working with the local population, relative to the approach taken by larger NGOs in this field. It concludes by proposing that a key new avenue for the international community to meet its developmental and environmental goals could be to support the work of local ENGOs through, for example, existing carbon markets. 相似文献

In public debate GMPs are oftenreferred to as being unnatural or a violationof nature. Some people have serious moralconcerns about departures from what is natural.Others are concerned about potential risks tothe environment arising from the combination ofhereditary material moving across naturalboundaries and the limits of scientificforesight of long-term consequences. To addresssome of these concerns we propose that anadditional element in risk assessment based onthe concept of familiarity should beintroduced. The objective is to facilitatetransparency about uncertainties inherent inthe risk assessment of the GMP. Familiarityconventionally involves data and experiencerelating to the plant species and the ecosystemin question. We would like to extend thisconcept to the molecular level of plantbreeding and suggest that GMP characteristicsshould be compared to a reference baselinedetermined by conventional breeding techniques.Three GMPs are ranked according to familiarityat the plant and ecosystem level and themolecular level. The approach may help tointegrate discussion of the scientificarguments and moral questions raised in thedebate about GMOs by providing an operationalscheme within which moral concerns are broughtwithin the framework of science-based riskassessment. 相似文献
