Caribbean, on the Sargassum road
Since 2011, the daily life of millions of inhabitants of Caribbean coasts has radically changed with the sudden arrival of tons of Sargassum.
From Mexico to Brazil, passing by the Dominican Republic, Guadeloupe, Saint-Barthelemy and Martinique, each country is implementing initiatives to fight against Sargassum.
Whether by trying to detect them, store them, recycle them, transform them or study them, the entire Caribbean is still trying to understand and to battle the phenomenon in order to limit their consequences on the long term economy, the environment and health; to stop the advance of Sargassum.
Brown algae, green ideas
Where does Sargassum come from? What are its connections to global warming? Why is it an issue for the environment, the economy and for health? Once collected, how to value it?
Today, a lot of research is underway and possibilities are emerging. Sargassum could become a fertilizer, a fuel or activated carbon against pesticides. What if this invasive alga was turned into a resource?
We discover three projects for the valorisation and transformation of Sargassum in Martinique and Guadeloupe, through the eyes of Sanand and Max-Manory, two Port-Louis High School (Guadeloupe) members of the Sentinel Club.
