Saint Lucia innovates to address Sargassum seaweed
Sargassum is free-floating brown macro-algae that lives in the temperate and tropical oceans. In the open ocean, the floating seaweed provides important ecosystem services by acting as habitats for a diverse group of marine animals.
Since 2011, excessively large quantities of Sargassum have accumulated in the Caribbean Sea, only to wash ashore in several Caribbean countries. A young entrepreneur in St Lucia recognized an opportunity to capitalize on this freely available resource to create valuable organic agricultural inputs, which could in turn reduce and eventually replace the environmentally harmful synthetic chemicals used to grow food.
