Seaweed production is undergoing a rapid global expansion at a time of accelerating climate change, hence raising new challenges for producers and the environment. Currently, a relevant proportion of seaweed production goes to human consumption and the polysaccharide industry, supporting the livelihood of millions of small-scale farmers and processors, including women. After 2010, a significant expansion of the global seaweed cultivation industry has been driven by the growing commercial demand for higher value seaweed-derived products, such as cosmetics, pharmaceuticals, including agarose used in clinical trials, biostimulants and biomaterials among other uses opening new market opportunities. On the other hand, seaweed production has several challenges related to their global expansion like the consolidation of new market opportunities, productivity sustainability, installation of proper and global biosecurity standards, and risk management such as diseases and grazing outbreaks, offshore cultivation conditions, eutrophication and climate change. In relation to these challenges, R&D&I and novel global and country level policies are required.
