Facing the seamount in Brittany, one treasure declared: “They have a tremendous effort to adapt.”

Coastal residential areas and additional industries are threatened by the mountain, coastal erosion is curbed and submergence is monitored. I urgently need help, details about Alain Hénaff, conference director at the University of Brest.

Human activities, artificial management of the coasts and air conditioning accelerate the rise of sea levels, reducing coastal erosion and the risk of submergence. The sea level is 1.1 meters at 2,100 meters altitude, see GIEC, and sweep over the coasts, according to the Breton notice. Face the danger of submersion in the sea in the south of Finistère, in Treffiagat. The houses are behind the Léhan dune and are destroyed by the residents et les habitants fromt devoir partir. “It is an exceptional situation at the moment, However, this is only effective if there is a risk of the multiplier being submerged“said Alain Hénaff, head of geographical conferences at the European University Institute of the Sea (IUEM) and at the UBO, invited by France Bleu Breizh Izel on December 26th.

Reculer, naturaliser, se barricade or partir

What solutions are available to you? “On peut d’abord Habitat adapterle recculer au fur et à mesure de l’élévation de la sea et l’érosion, Détaille l’enseignant-chercheur. You may imagine that you can use it – until the last day in recent years – nature’s process to recompose the dunes, to reform the shorelines. It is obvious that hoaxes are no longer possible and that they do not necessarily need to be recultivated. You have the appropriate option “se barricader, constructor of the murs, of the enrochements, Digue lever. With this uncertainty: It’s just not possible to do these things to withstand a wall from a storm?” Last chance, “If you retreat, it is that you are on the shore of the coastal land, that is the risk of going perdu.”certain residents leave the Côte. That’s what’s happening to Treffiagat.

In Brittany, Alain Hénaff voit “deux Sectors, commerce and tourism, more touchés for these phenomenal climates. The campsites, the leisure ports and the exchanges in the commercial ports. The souvent ports were constructed à la Nôtre from earlier eras. If you imagine that the level of the sea is stabilized, these infrastructures will no longer function.” Parmi the measures of possible adaptation: barriers against floods, rehabilitation of the dunes, measures of inconstruction, as well as the restoration of natural spaces in Alentours.
