5 years in the past, the American farmed-seaweed trade barely existed. Wild seaweeds had been harvested for hundreds of years by Indigenous peoples on each coasts, for a variety of makes use of together with insulation, treatment, and fertilizer. Later, seaweeds have been then harvested from the wild for agricultural fertilizers and the cosmetics trade. As for kelp farms, although, there have been solely a smattering of them in Maine, promoting merchandise to eating places or natural-foods shops. Most farmed seaweed out there within the U.S.—together with the acquainted sushi nori sheets—got here from Asia.
At this time, shoppers can discover burgers, chips, and even a cannabis gummy comprised of home farmed seaweed, and a current Nielsen report estimated the worth of the edible seaweed trade to be $1.87 billion within the U.S. One explicit kind of seaweed, kelp, has come to the fore: Greater than 2 million pounds have been pulled from coastal U.S. waters through the 2022-2023 season, and specialists predict that the 2023–2024 season will probably be even bigger.
What’s driving this progress? The reply goes past seaweed’s industrial purposes or the truth that Individuals are creating a style for kelp as a nutritious, low-calorie food. Scientists say this seaweed additionally provides a mess of ecosystem benefits. Kelp can pull extra carbon out of the environment—with some estimating that it sequesters a minimum of 10 times more carbon than a terrestrial crop. It reduces ocean acidification, too, and removes the excess nitrogen that feeds large algal blooms, a menace to different marine life.
This scientific proof of kelp as a regenerative crop that would save our seas has helped the trade appeal to fast funding—in keeping with our estimates, greater than $300 million since 2017, from sources together with the federal authorities, companies, enterprise capital funds, coastal state spending, and nonprofits. Kelp may additionally assist local weather efforts on land, in industries starting from textiles to plastics to beef.
We’ll hint the rise of seaweed farming within the U.S. and profile small farmers who’re utilizing kelp to each mitigate local weather change and adapt to its impression.
As Silicon Valley and others flip their sights to this exceptional seaweed, the time is ripe to ask crucial questions on the way forward for an trade that might be quickly increasing. Will smallholder farmers, whose work has been pivotal in organising home seaweed manufacturing, reap the advantages of the trade’s progress? Or will multinationals transfer in, rising seaweed at scale—doubtlessly boosting ecosystem advantages, however maybe additionally introducing the environmental repercussions of monocropping? And can federal cash move to small farms in addition to giant?
Rules are at subject as nicely. Small coastal growers now navigate a tangle of laws, with nobody entity claiming oversight. The country’s first seaweed bills now sit in Congress, with the potential to unleash a brand new spherical of funding in an trade that’s nonetheless not tracked by the U.S. Division of Agriculture or the Nationwide Oceanic and Atmospheric Administration. Might giant traders leapfrog to offshore farms, the place the regulatory setting could also be extra permissible?
On this sequence, we’ll ask these questions and extra. For context, we’ll hint the rise of seaweed farming within the U.S. and profile small farmers who’re utilizing kelp to each mitigate local weather change and adapt to its impression. We’ll discover how scientists are creating extra environment friendly methods of rising kelp whereas additionally defending the way forward for wild kelp forests.
