The webinar on “The status and future of seaweed farming in the Mediterranean and the Black Sea” was held online on 15 July 2021 and was organized by the GFCM. The webinar aimed to discuss the state of play of algae production and processing in the region, the potential and benefits of seaweed farming along with its applications and future perspectives. The webinar introduced the seaweed and microalgae sector in the Mediterranean and the Black Sea and discussed its current status in light of its potential for the region and its relevance within the GFCM 2030 Strategy for sustainable fisheries and aquaculture in the Mediterranean and the Black Sea. Panellists reviewed the environmental, economic and health benefits of increased seaweed production and consumption and exchanged information about future development plans and possible applications, including as a source of food and as a climate change mitigation resource. The importance of leveraging the untapped potential of seaweed was recognized throughout the webinar, but it was also acknowledged that doing so would require improved data quality, additional research, cooperation among stakeholders, regulatory frameworks as well as reduced barriers to financing.
