| Abstract |
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. |
