La balade sous le soleil permet d’abord de d\u00e9couvrir une plage qui \u00e9tait de sable fin il y a 50 ans et est aujourd’hui constell\u00e9e de rochers granitiques. Elle montre que les paysages sont fa\u00e7onn\u00e9s par le vivant : l’impermanence perp\u00e9tuelle du littoral nous am\u00e8ne \u00e0 nous r\u00e9concilier avec l’impermanence.<\/p>\n\n\n\n

\"\"<\/a><\/figure>\n\n\n\n

Akira a expliqu\u00e9 que le littoral \u00e9tait une interface de 6 sph\u00e8res: l’atmosph\u00e8re (ciel, temp\u00eate, vents et climat), l’hydrosph\u00e8re (eau sal\u00e9e, eau douce et le cycle de l’eau), la biosph\u00e8re (la v\u00e9g\u00e9tation, les hirondelles des rivages, les hu\u00eetres: des exp\u00e9riences de r\u00e9cifs huitriers permettent de lutter contre la houle…), la lithosph\u00e8re (les rochers, le min\u00e9ral) l’anthroposph\u00e8re (les am\u00e9nagements humains) et la cryosph\u00e8re\u00a0 (les glaciers). Ces 6 sph\u00e8res sont une tresse de c\u00f4te, plut\u00f4t qu’un trait de c\u00f4te, form\u00e9e de ces 6 fils et quand on en fait bouger un, tout bouge.<\/p>\n\n\n\n

\"\"<\/a><\/figure>\n\n\n\n
\"\"<\/a><\/figure>\n\n\n\n

Nous sommes arriv\u00e9.es au vieux village de G\u00e2vres, village blotti, avec des maisons mitoyennes face \u00e0 l’Est, dos au vent, plus r\u00e9silientes finalement que les maisons r\u00e9centes avec de larges baies vitr\u00e9es orient\u00e9es \u00e0 l’Ouest qui peinent en cas de forts vents.<\/p>\n\n\n\n

On ne peut pas lutter \u00e9ternellement contre la mer, les dunes bougent, les digues peuvent s’\u00e9crouler faute d’entretien. Ne faudrait-il pas accepter que G\u00e2vres redeviennent l’\u00eele qu’elle \u00e9tait ?<\/p>\n\n\n\n

Il ne faut pas de mal-adaptation au changement climatique mais une vraie adaptation, avec des solutions fond\u00e9es sur la nature et pens\u00e9es avec les parties prenantes, en redonnant du pouvoir d’agir aux habitant.e.s.\u00a0<\/p>\n\n\n\n

A G\u00e2vres, plut\u00f4t que continuer \u00e0 cr\u00e9er des digues qui ont des impacts n\u00e9gatifs \u00e0 terme sur le sable de la plage, ont \u00e9t\u00e9 cr\u00e9\u00e9es des zones de restauration de la dune (ganivettes). Les racines des plantes aux noms po\u00e9tiques: chiendent des dunes, criste marine, chardon bleu… fixent le sable.<\/p>\n\n\n\n

Ces zones sont surveill\u00e9es et entretenues par des habitant.e.s dans le cadre d’un observatoire citoyen encadr\u00e9 par l’universit\u00e9 de Bretagne Sud.<\/p>\n\n\n\n

Cette balade a \u00e9t\u00e9 tr\u00e8s inspirante, elle nous a montr\u00e9 que nous sommes tress\u00e9.e.s dans un r\u00e9seau d’humains.<\/p>\n\n\n\n

\"\"<\/a><\/figure>\n\n\n\n

Apr\u00e8s un apr\u00e8s-midi riche, selon les altercyclistes, de plage, balades ou exp\u00e9ditions \u00e0 Port-Louis, la vaisselle d’un soir a permis d’exprimer des talents de cr\u00e9ation de chansons: \u00ab\u00a0et tu frottes frottes frottes ce couteau qui te coupe\u00a0\u00bb<\/p>\n\n\n\n
