Vincent Doumeizel Champions Seaweed‍ as a Super Solution for global Crises

⁤ ⁣ Updated June 08, 2025

Lesconil,⁣ France – In the⁢ Brittany fishing port of Lesconil, vincent Doumeizel, a ⁤senior advisor to the UN Global⁣ Compact,‍ champions⁣ seaweed as⁣ a pivotal‌ solution to‌ global challenges.⁢ He views this marine algae as a means ⁤to feed the‌ planet, ⁣restore‍ oceans, combat climate change, and ​replace⁢ plastics.

Doumeizel,a leading⁢ figure in the “seaweed revolution,” co-authored The Seaweed Manifesto in 2020,advocating for the use of algae ⁣to address climate,environmental,food,and‍ social crises. He believes seaweed is the world’s greatest untapped resource.

Marine algae, which emerged over a billion years ⁢ago, played a crucial role ⁣in oxygenating the‌ atmosphere. Doumeizel’s interest in seaweed was sparked during‍ a trip to Okinawa,⁣ Japan, where he observed the ‍longevity of residents who ⁤consumed it regularly. ‍Seaweed is rich in vitamins, omega-3 fatty acids, fibers, and ​proteins.

while agriculture contributes considerably to ⁤greenhouse gas ‌emissions, seaweed cultivation requires no land, fertilizers, or freshwater. Research suggests that feeding red seaweed to cows could‌ reduce their methane emissions by up ​to 90 percent. Seaweed also captures more carbon per acre than land vegetation ​and can be transformed ⁤into bioplastics, biofuels, textiles, and pharmaceuticals.

Doumeizel recently launched a⁣ comic ‌book, The Seaweed ​Revolution, which mirrors his real-life advocacy. ‌He showcases various seaweed-based​ products, including ⁢sunglasses made from plankton, biodegradable garbage bags, and T-shirts spun from algae fibers.

The seaweed ‌industry is experiencing growth, with production more than tripling since 2000, reaching 39 million⁤ tonnes annually. The market is valued at $17 billion, with potential⁤ for an additional ⁣$12 billion by ‍2030 through investments in various applications.however, the ⁣industry lacks⁢ comprehensive ‌legislation and guidance.

Seaweed⁤ cultivation is also driving feminist​ change. Approximately 40 percent of seaweed ​start-ups worldwide are led by women. In Tanzania, the seaweed trade has empowered ​women,⁣ who retain nearly​ 80 percent of the profits, ⁢enabling them to build schools‌ and improve their livelihoods.the Global Seaweed Coalition is funding⁤ initiatives ⁢to teach women maritime skills to address challenges posed by ⁤climate change.

Climate change poses a threat to‍ seaweed habitats, with significant losses reported​ in regions like California, Norway, and Tasmania. Doumeizel⁣ emphasizes the importance⁢ of preserving “sea ⁣forests” and will unveil a UN Seaweed Task Force‍ at the ⁣upcoming UN‍ Ocean Conference. This ⁣task force aims to consolidate global efforts in regulation,research,and development.

The task force proposal has ‌garnered support from countries including Madagascar, Indonesia, South‌ Korea, and ⁢France,‍ with a draft resolution expected at the UN General Assembly this fall and a vote ⁤anticipated in 2026.

Doumeizel envisions turning oceanic overgrowth, such as sargassum blooms, into sustainable resources like fertilizers, bricks, and textiles.He advocates for farming​ the ​ocean to heal it, inviting a shift ​from ​Stone Age hunter-gatherer practices to sustainable cultivation.

What’s next

The UN Seaweed Task Force aims to establish global standards and centralize⁣ expertise, fostering responsible and sustainable scaling of the seaweed industry. The initiative seeks to unlock the full potential of ​seaweed as a solution to pressing global challenges.
