The concept of coastal lookouts was born in Australia, since taken over in many countries faced with rising sea levels which inexorably eat away at the coastline. In Saint-Brévin, as elsewhere, you have to choose strategic observation sites, which are constantly changing, depending on currents, swells or storms. All the photos taken by the lookouts feed into monitoring sheets which will allow a better understanding of the phenomena that lead to this erosion.
“These photos are compiled on a site at the town hall, and are observed by scientists, in particular from the University of Nantes, who will be able to assess the coastline. On the other hand, these photos will also be looked at by the technical services to understand the actions necessary to protect the coast.“, explains Jean-François Golhen, municipal councilor of Saint-Brévin-les-Pins, delegate for the Sea and the Coastline.
