Seaweed farming can sequester carbon and generate income for fragile coastal communities, particularly women
WASHINGTON, August 16, 2023 - A new World Bank report estimates that ten emerging global seaweed markets have a potential growth of up to $11.8 billion by 2030. This monetary value comes with seaweed's ability to sink carbon, sustain marine biodiversity, employ women, and unlock value chains.
The Global Seaweed New and Emerging Markets Report 2023 analyses the commercial opportunities for new high-growth seaweed market applications. The report offers insights for entrepreneurs, investors, and policymakers towards ensuring the seaweed sector fulfils its potential now and into the future.
Today, most farmed seaweed is used for direct human consumption or fresh feed in aquaculture. In the future, seaweed products can displace fossil fuels in sectors such as textiles and plastics, sequester carbon, and generate income for fragile coastal communities. There are huge growth opportunities in many regions, as the current market is dominated by a few Asian countries which produce 98 percent of farmed seaweed.
"Growth in seaweed farming across the world will depend on sharing technology and knowledge between policy makers, financing institutions, the scientific community, the private sector, producers, and processors - leaving no one behind. With women's dominance in seaweed farming, the stage is set for catalyzing a truly global 'she-weed' revolution," said Valerie Hickey, the World Bank Global Director for the Environment, Natural Resources and Blue Economy.
The report focuses on 10 relatively new and emerging seaweed applications that have the greatest market opportunities outside the established sectors. In the short-term, the most promising new markets are projected to reach $4.4 billion by 2030, including biostimulants, animal feed, pet foods, and methane-reducing additives. Medium-term opportunities, include nutritional supplements, alternative proteins, bioplastics, and fabrics could reach a potential value of $6 billion. Long-term emerging markets are projected to reach $1.4 billion, for pharmaceuticals and construction materials, but with significant regulatory challenges and a high cost of product development.
"Seaweed farming demonstrates how development, climate, and nature work together to generate value and uplift communities. Seaweed farming will be a source of nutrition security as well as an alternative to synthetic fertilizer," said Martien van Nieuwkoop, World Bank Global Director for Agriculture and Food. "The World Bank is committed to help countries transform food systems towards better outcomes for people, planet and economies."
To fully realize seaweed market's potential, the industry will need to overcome several key issues. The largest challenge is the availability of seaweed itself, due to limitations in volume, and consistency and quality of the supply. As more applications of seaweed are developed, pricing and regulatory barriers may also emerge.
Despite these challenges, the climate and environment benefits of seaweed farming will help drive growth of potential emerging markets. As interest in "green" products continues to increase, many product developers have expressed a reliance on sustainability premiums to generate profits.
At a time when global resources are increasingly overstretched, it is particularly important that the world makes the most of resources, such as seaweed, that can both be swiftly regenerated and potentially help to regenerate ecosystems.
