Seaweed left an indelible mark during the 2021 UN Food Systems Summit and the 2021 United Nations Climate Change Conference, more commonly referred to as COP26, as an innovative nature-based solution towards achieving sustainable healthy diets as well as building economic and climate resilience. Hailed as a revolutionary superfood, seaweed is also seen as a means to address social and gender disparity in low- and middle-income stakeholders in the supply chain. We spoke to Vincent Doumeizel, advisor to the UN Global Compact and The Seaweed Manifesto, as well as the author of the new book ‘La Revolution des Algues’, for his insights and opinions on this superfood for the future.
