Tulum I : Algues brunes sur la plage<\/h1>\n\n

Un tapis de sargasses puantes nous g\u00e2che la baignade en mer<\/p>\n\n

Par Renate R\u00fcger, 12 avril 2026<\/p>\n\n

Mexique<\/strong> \u2013 \u00c7a sent l’\u0153uf pourri. Des algues brunes, appel\u00e9es sargasses, s’accumulent sur la plage devant notre h\u00f4tel \u00e0 Tulum. Nous sommes venus ici en taxi, ferry et voiture de location pour voir les ruines mayas sur la c\u00f4te. Le petit h\u00f4tel avec piscine et plage priv\u00e9e nous pla\u00eet beaucoup. Nous ne voulons pas aller dans la mer \u00e0 cause du sargassum qui, en se d\u00e9composant, d\u00e9gage cette odeur d\u00e9sagr\u00e9able de soufre. Hier encore, le sable \u00e9tait propre et l’acc\u00e8s \u00e0 l’eau libre, nous raconte le gar\u00e7on d’h\u00f4tel. Le sargassum est arriv\u00e9 pendant la nuit. Sur la plage d’\u00e0 c\u00f4t\u00e9, il y en a peut-\u00eatre moins, ajoute-t-il en nous montrant le chemin. Non, ici des employ\u00e9s pellettent bien le sargassum sur le c\u00f4t\u00e9, mais leur combat contre les tas bruns ressemble \u00e0 un combat contre des moulins \u00e0 vent. <\/p>\n\n

Sur la plage de l’h\u00f4tel voisin, ce n’est pas mieux. Ici aussi, tout est couvert d’algues brunes. <\/figcaption><\/figure>\n\n

Cette chose puante vient de l’Atlantique. Nous avions d\u00e9j\u00e0 vu d’immenses tapis d\u00e9rivant vers l’ouest lors de notre travers\u00e9e de l’Atlantique. Depuis 2011, les chercheurs observent la formation r\u00e9currente de la \u00ab Grande Ceinture de Sargasses de l’Atlantique \u00bb, qui s’\u00e9tend de l’Afrique de l’Ouest au golfe du Mexique. La surfertilisation, la d\u00e9forestation de l’Amazonie et l’augmentation de la temp\u00e9rature de l’eau due au changement climatique sont cit\u00e9es comme causes. Le moment et l’endroit exacts o\u00f9 les algues s’\u00e9chouent d\u00e9pendent du vent et des vagues, mais le Mexique, la R\u00e9publique dominicaine et la Floride sont les pays les plus touch\u00e9s. Tulum est consid\u00e9r\u00e9 comme un point chaud : d\u00e9but 2026, il y avait d\u00e9j\u00e0 quatre fois plus d’algues brunes que l’ann\u00e9e pr\u00e9c\u00e9dente. Depuis les ruines mayas aussi, on voit des montagnes de sargassum \u2013 et des bateaux de p\u00eache qui y sont \u00e9chou\u00e9s. <\/p>\n\n
