Chile strengthens marine conservation with 10-year ban on harvesting giant kelp

Chile has introduced a ten-year protection period for the giant kelp Macrocystis pyrifera in the Magallanes Region, aiming to preserve one of the most important marine ecosystems along the coast of Chilean Patagonia. The initiative focuses on safeguarding underwater forests that support biodiversity and the long-term sustainability of coastal fisheries.

The decision follows collaborative efforts between scientists, authorities and artisanal fishing communities, who emphasised the ecological value of protecting these habitats, according to El Maipo, a partner of TV BRICS.

Giant kelp is one of the largest marine organisms on Earth and can grow to heights of up to 70 metres. Thriving in cold, nutrient-rich waters, it forms dense underwater forests that provide shelter, breeding grounds and feeding areas for more than 300 marine species. One of the most important inhabitants of these ecosystems is the southern king crab, Lithodes santolla.

These kelp ecosystems are also known for their role in regulating the climate. By absorbing significant amounts of carbon dioxide, they act as natural “blue carbon” reservoirs, contributing to global efforts to address climate change.

Scientists note that Patagonia’s kelp forests remain among the most intact in the world, making their protection particularly significant for maintaining marine biodiversity and supporting sustainable coastal livelihoods.
