Abstract Like many Caribbean coastal ecosystems, the Simpson Bay Lagoon in Saint Martin suffers from heavy development, wastewater pollution, and overexploitation. These pressures have severely degraded its ecological integrity, causing significant environmental impact as well as negative socio-economic consequences. Local livelihoods depend on important ecosystem services provided by the Simpson Bay Lagoon, such as storm protection and water purification. A major cause for the continued degradation of the Simpson Bay Lagoon is that decision-makers undervalue these ecosystem services. This study conducts an economic valuation of the Simpson Bay Lagoon to solve this undervaluation, providing the first economic valuation of a Caribbean island coastal lagoon. To estimate the economic value of the Simpson Bay Lagoon, this paper employs a choice experiment, which is embedded in a larger household survey among residents of Saint Martin. The findings of the choice experiment reveal that the Simpson Bay Lagoon in its current environmental state is worth US$12.1 million per year to the residents of Saint Martin. Besides an economic valuation, this paper also scrutinizes the welfare benefits of improved environmental management. Two environmental management scenarios are evaluated: the installation of a sewage treatment plant and mangrove restoration. The installation of a sewage treatment plant would enhance the annual economic value to US$16.5 million, mangrove restoration to US$23.0 million, and the implementation of both measures to US$26.3 million. Hence, ameliorating the ecological integrity of the Simpson Bay Lagoon through improved environmental management proves to be a promising venture for the environment, society, and economy of Saint Martin.

使用选择实验方法评估加勒比沿海泻湖:以圣马丁辛普森湾泻湖为例

摘要 像许多加勒比海岸生态系统一样,圣马丁的辛普森湾泻湖遭受严重的开发、废水污染和过度开发。这些压力严重破坏了其生态完整性,造成了重大的环境影响以及负面的社会经济后果。当地的生计依赖​​于辛普森湾泻湖提供的重要生态系统服务,例如风暴保护和水净化。辛普森湾泻湖持续退化的一个主要原因是决策者低估了这些生态系统服务的价值。本研究对辛普森湾泻湖进行了经济估值,以解决这种低估的问题,提供加勒比岛屿沿海泻湖的第一个经济估值。为了估算辛普森湾泻湖的经济价值,本文采用了一项选择实验,该实验嵌入在圣马丁居民的更大家庭调查中。选择实验的结果表明,在目前的环境状态下,辛普森湾泻湖每年对圣马丁的居民来说价值 1210 万美元。除了经济评估外,本文还仔细研究了改善环境管理的福利。评估了两种环境管理方案:安装污水处理厂和恢复红树林。污水处理厂的安装将使每年的经济价值增加到 1650 万美元,红树林恢复到 2300 万美元,两项措施的实施将增加到 2630 万美元。因此,
