摘要

长期以来，各国政府一直面临着经济发展与保护自然之间的潜在权衡。这对于热带和亚热带岛屿来说尤其如此，因为那里的红树林最多。受特立尼达和多巴哥中央政府之前的酒店发展计划的激励，我们采用离散选择实验（DCE）来调查多巴哥邦雅阁泻湖和布库湾居民对红树林生态系统服务（ES）的偏好。在保护红树林和促进经济发展之间的权衡背景下，通过一个假设的研究区域的酒店项目，研究了偏好。我们使用层次贝叶斯Logit模型，探索两个不同的支付期限，5年和25年，独立进行，也合并在模型中，允许选择确定性和个人特征。我们发现，受访者对红树林生态系统有一致的支付意愿（WTP），并且由于酒店开发中红树林的损失所带来的不利影响，他们对支付范围普遍不敏感。DCE和事后（后续）访谈表明，公众强烈支持旨在长期保护红树林的政策。

Mangroves and economic development in Tobago: Incorporating payment horizons, choice certainty and ex-post interviews in discrete choice experiments

Governments have long faced potential trade-offs between economic development and protecting nature. This is particularly true for tropical and sub-tropical islands where most mangroves are found. Motivated by Trinidad and Tobago's central government's prior hotel development plans, we employ a discrete choice experiment (DCE) to investigate residents' preferences for mangrove ecosystem services (ES) in the Bon Accord Lagoon and Buccoo Bay, Tobago. Preferences were investigated in the context of a trade-off between conserving mangroves and promoting economic development through a hypothetical hotel project in the study area. We use a Hierarchical Bayesian Logit Model, exploring two distinct payment horizons, 5 and 25-years, undertaken independently and also merged in models that allow for choice certainty and individual characteristics. We find that respondents have consistent willingness-to-pay (WTP) for mangrove ES and exhibit general insensitivity to the payment horizons due to perceived disbenefits associated with mangrove loss from hotel development. The DCE and ex-post (follow-up) interviews suggest that there is strong public support for policies aimed at long-term protection of mangroves.

期刊介绍： Ecological Economics is concerned with extending and integrating the understanding of the interfaces and interplay between "nature''s household" (ecosystems) and "humanity''s household" (the economy). Ecological economics is an interdisciplinary field defined by a set of concrete problems or challenges related to governing economic activity in a way that promotes human well-being, sustainability, and justice. The journal thus emphasizes critical work that draws on and integrates elements of ecological science, economics, and the analysis of values, behaviors, cultural practices, institutional structures, and societal dynamics. The journal is transdisciplinary in spirit and methodologically open, drawing on the insights offered by a variety of intellectual traditions, and appealing to a diverse readership. Specific research areas covered include: valuation of natural resources, sustainable agriculture and development, ecologically integrated technology, integrated ecologic-economic modelling at scales from local to regional to global, implications of thermodynamics for economics and ecology, renewable resource management and conservation, critical assessments of the basic assumptions underlying current economic and ecological paradigms and the implications of alternative assumptions, economic and ecological consequences of genetically engineered organisms, and gene pool inventory and management, alternative principles for valuing natural wealth, integrating natural resources and environmental services into national income and wealth accounts, methods of implementing efficient environmental policies, case studies of economic-ecologic conflict or harmony, etc. New issues in this area are rapidly emerging and will find a ready forum in Ecological Economics.
