The GlobalSeaweed Superstar project, funded by the UK’s Global Centre on Biodiversity for Climate (GCBC), will involve some of the world’s most prominent seaweed scientists and industry leaders. It aims to produce a global strategy, called the seaweed breakthrough, to be launched at COP31 in 2026 to urgently protect wild stocks.
Importance of the seaweed industry
The Scottish Association for Marine Science (SAMS) highlighted that seaweeds are vital for the functioning of the marine ecosystem, supporting an immense biodiversity of marine organisms. They also noted that there are also more than six million seaweed farmers in 56 countries worldwide who rely on seaweed for their livelihoods. The vast majority of these farmers are in Asia, which accounts for more than 95 percent of the sector.
SAMS has also emphasised that wild seaweed communities are predicted to lose up to 71 percent of their current distribution by 2100, either through overharvesting or climate-driven impacts, such as pollution, invasive species or pest and disease outbreaks.
Seaweed industry is overlooked
Project leader Prof Elizabeth Cottier-Cook of SAMS, a partner of UHI, said in a press release: “Despite their significant ecological and economic importance, wild seaweeds receive minimal or no protection through policies or legislation globally.”
Cottier-Cook added: “We’re not just looking at a looming biodiversity crisis; there is an entire economy that supports millions of families in developing nations. Women, who are integral to seaweed cultivation, are also able to be economically active in this industry, in areas where few opportunities exist.”
The seaweed cultivation industry is one of the fastest-growing of all aquaculture sectors, with an annual growth rate of 10 percent, a value in excess of $14 billion and a production of 35 million tonnes in 2019.
A superstar collaboration
GlobalSeaweed Superstar will also involve a core research team of Prof Juliet Brodie of the UK’s Natural History Museum and Prof Lim Phaik Eem of the University of Malaya, as well contributions from the United Nations University Comparative Regional Integration Studies (UNU-CRIS). This first round of grants was officially announced this week by the Global Centre on Biodiversity for Climate (GCBC) - a UK Official Development Assistance (ODA) programme that funds research into nature-based solutions to climate change and poverty reduction.
The project is one of 13 successful applicants selected from a total of 155 in this first round of grants. According to the World Economic Forum, nearly half of the global gross domestic product depends on nature, and yet biodiversity is disappearing quicker than at any time throughout history. A 2019 IPBES report found that around one million plant and animal species are currently threatened with extinction.
In the official grant announcement shared on the GCBC website, Professor Gideon Henderson, chief scientific adviser, UK department for environment, food and rural affairs, said: “We are very excited to announce the first round of grant award recipients through the Global Centre on Biodiversity for Climate (GCBC) in partnership with RBG Kew and DAI Global UK. This is a significant milestone and the first step towards delivering climate solutions for vulnerable populations by working in partnership with organisations across the Global South to harness nature’s potential to enhance climate resilience and improve livelihoods.”
