小岛屿发展中国家（SIDS）对气候变化的责任最小，尽管它们在易受气候引起的灾害方面承受着不成比例的负担。许多小岛屿发展中国家的经济也高度依赖旅游业，其中许多旅游业发生在潜在危险的沿海地区，并与环境质量密切相关。尽管促进沿海基础设施投资对于降低脆弱性和增强韧性具有重要意义，但探索投资的经济回报以证实这种投资的商业案例的研究却很缺乏。本文解决了这一研究缺口，开发了一个估算岸线稳定经济效益的模型，并通过对巴巴多斯2420万美元沿海基础设施投资的应用说明了该方法。结果表明，投资对游客和居民都产生了显著的效益，并减少了海滩侵蚀和财产损失。面对数据限制，该方法是通用的，为支持扩大现有投资的决策提供证据，并可以为新投资的设计提供支持和信息。
Small Island Developing States (SIDS) are the least responsible for climate change, though they bear a disproportionate burden in terms of vulnerability to climate-induced disasters. The economies of many SIDS are also highly dependent on tourism, much of which occurs in potentially hazardous coastal areas and are closely linked to environmental quality. Despite the importance of catalyzing investment in coastal infrastructure to reduce vulnerability and enhance resilience, there is a paucity of research exploring the economic returns to investment to substantiate a business case for this investment. This paper addresses this research gap and develops a model for estimating the economic benefits of shoreline stabilization and illustrates the approach with an application to a US$24.2 million coastal infrastructure investment in Barbados. Results show that the investment generated significant benefits for both tourists and residents, as well as reduced beach erosion and property damage. The approach is versatile facing data constraints, provides evidence to support decisions to scale-up existing investments, and can support and inform the design of new investments.
