Sea level rise (SLR) is posing a great inundation risk to coastal areas. Some coastal nesting species, including sea turtle species, have experienced diminished habitat from SLR. Contingent valuation method (CVM) was used in an effort to assess the economic loss impacts of SLR on sea turtle nesting habitats for Florida coasts; and to elicit values of willingness to pay (WTP) of Central Florida residents to implement certain mitigation strategies, which would protect Florida's east coast sea turtle nesting areas. Using the open-ended and dichotomous choice CVM, we sampled residents of two Florida communities: Cocoa Beach and Oviedo. We estimated the WTP of households from these two cities to protect sea turtle habitat to be between $42 and $57 per year for 5 years. Additionally, we attempted to assess the impact of the both the respondents' demographics and their perception toward various situations on their WTP value. Findings include a negative correlation between the age of a respondent and the probability of an individual willing to pay the hypothetical WTP amount. We found that WTP of an individual was not dependent on prior knowledge of the effects of SLR on sea turtle habitat. The greatest indicators of whether or not an individual was willing to pay to protect sea turtle habitat were the respondents' perception regarding the trustworthiness and efficiency of the party which will implement the conservation measures and their confidence in the conservation methods used. Respondents who perceive sea turtles having an effect on their life were also more likely to pay.
海平面上升(SLR)正对沿海地区构成巨大的淹没风险。一些沿海筑巢物种,包括海龟物种,因海平面上升而栖息地减少。本研究采用条件价值评估法(CVM)来评估海平面上升对佛罗里达海岸海龟筑巢栖息地造成的经济损失影响;并获取佛罗里达中部居民为实施某些缓解策略(这些策略将保护佛罗里达东海岸海龟筑巢区)的支付意愿(WTP)值。我们使用开放式和二分选择CVM,对佛罗里达的两个社区——可可海滩和奥维多的居民进行了抽样调查。我们估计,这两个城市的家庭为保护海龟栖息地,在5年时间里每年的支付意愿在42美元至57美元之间。此外,我们试图评估受访者的人口统计学特征及其对各种情况的认知对其支付意愿值的影响。研究结果包括受访者年龄与个人愿意支付假设支付意愿金额的概率之间呈负相关。我们发现,个人的支付意愿并不取决于其对海平面上升对海龟栖息地影响的先验知识。个人是否愿意支付以保护海龟栖息地的最大指标是受访者对实施保护措施一方的可信度和效率的认知,以及他们对所采用保护方法的信心。认为海龟对其生活有影响的受访者也更有可能支付费用。
