本文介绍了一项跨学科的研究，重点是在莫雷亚(法属波利尼西亚)海岸线变化中发挥作用的社会生态机制。在之前一项研究的基础上，综合了1977年至2018年对该岛海岸线监测工作的结果，我们联合分析了科学和地方对海岸变化和沿海装甲在莫雷亚的影响的看法。基于生态和民族志数据(对莫雷亚居民和地方当局代表的111次半结构化访谈)，我们分析了近岸居民修改海岸线的驱动因素，以及海岸人工化对近岸海洋生物多样性和地形的感知影响。我们还讨论了更广泛的经济和政治背景，在这些背景下，该岛的海岸线正在日益改变。总体而言，我们的研究强调了对侵蚀加剧的看法以及执行不力的法规如何通过各种私人开发项目推动海岸线的逐步装甲。我们讨论了后者如何对科学家和居民产生了有争议的社区范围内的经济、社会和生态影响。
This paper presents a transdisciplinary study focusing on the socio-ecological mechanisms at play in the alteration of Moorea's (French Polynesia) coastline. Building on a previous study synthesizing the results from monitoring efforts of the island's coastline from 1977 to 2018, we offer a joint analysis of scientific and local perceptions of coastal changes and of the impacts of coastal armoring in Moorea. Drawing on ecological and ethnographic data (111 semi-structured interviews of Moorea residents and representatives from local authorities), we analyze the drivers invoked by near-shore residents to modify their coastline as well as the perceived effects of coastal artificialization on the near-shore marine biodiversity and topography. We also address the broader economic and political contexts under which the island's coastline is being increasingly transformed. Overall, our study highlights how the perceptions of increased erosion coupled to poorly enforced regulations drive the progressive armoring of the coastline through a diversity of private-based developments. We discuss how the latter have, both for scientists and residents, controversial community-wide economic, social, and ecological impacts.
