The State of the World’s Seaweeds 2025 presents a global assessment of seaweed biodiversity, production, trade and sustainability, synthesising ecological and socio-economic evidence to inform conservation and responsible industry growth.

It highlights trends in wild harvesting and aquaculture, pressures on coastal ecosystems, governance gaps, and opportunities to strengthen sustainable management and equitable value chains. The analysis supports improved data systems, policy coherence and investment in climate-resilient seaweed sectors.
