The perception of climate-related coastal risks and environmental changes on the Rangiroa and Tikehau atolls, French Polynesia: The role of sensitive and intellectual drivers
Abstract : French coastal policies have recently put greater emphasis on the need to better inform coastal populations about
coastal risks in the context of climate change, in particular in French overseas territories that are nationally
recognized as hotspots. It is therefore critical to further assess local populations' knowledge and perceptions of
climate-related coastal risks. In this respect, we ran a social survey among inhabitants of two atolls of French
Polynesia in the Pacific Ocean, using a questionnaire and semi-structured interviews largely based on images of
landscapes. The results show that (1) coastal risks are not considered as a danger but only as a problem, and that
(2) inhabitants have a very clear perception of the changes that have occurred locally over the last 70 years with
respect to weather, climate, corals and beaches. (3) Interviewees generally show some knowledge about the
notion of global climate change and its potential local impacts. (4) However, a multiple correspondence analysis
distinguishes four groups (the ‘informed’, ’poorly informed, ‘uninformed’ and ‘distant’ groups) separated by age
and gender, but also by levels of education and urbanization. The discussion therefore focuses on the most
important drivers of climate change perception, showing a disconnection between atolls and generations: rural
and older inhabitants present more sensitive mechanisms of risk perception and urban and younger interviewees
more intellectual ones. A major challenge consists in bringing these dimensions closer by better integrating, on
an intellectual level, local climate-related coastal risks into school programs, and by defining, on a more sensitive
level, an ambitious cultural and environmental policy to allow young generations to keep contact with their
original living environment. Highlighting the interest of this survey, risk management and adaptation policies
now support the reactivation of local knowledge and practices.
