Seaweed farming, also known as kelp farming, is the practice of cultivating and harvesting seaweed. This agricultural practice has gained significant attention in recent years due to its potential to mitigate climate change, improve economic conditions, and reduce fishing pressure.
What is Seaweed Farming?
Seaweed farming involves the cultivation of various species of seaweed, including Eucheuma spp., Kappaphycus alvarezii, Gracilaria spp., Saccharina japonica, Undaria pinnatifida, Pyropia spp., and Sargassum fusiforme. These species are used for a variety of purposes, including the production of carrageenan, a gelling agent, and agar, a gel-like substance. Some species are also consumed after limited processing.
History of Seaweed Farming
Seaweed farming has been practiced for centuries in various parts of the world. However, it has gained significant attention in recent years due to its potential to mitigate climate change. The Food and Agriculture Organization (FAO) reported that world production of seaweed in 2019 was over 35 million tonnes.
Why is Seaweed Farming Important?
Seaweed farming is considered a carbon-negative crop, meaning that it absorbs more carbon dioxide from the atmosphere than it produces. This makes it a potential tool for climate change mitigation. The IPCC Special Report on the Ocean and Cryosphere in a Changing Climate recommends further research attention on seaweed farming as a mitigation tactic. World Wildlife Fund, Oceans 2050, and The Nature Conservancy publicly support expanded seaweed cultivation.
Key Facts and Statistics
- The largest seaweed-producing countries as of 2022 are China (58.62%) and Indonesia (28.6%).
- The global seaweed extract market was valued at $16.5 billion in 2023, with strong projected growth.
- Seaweed farming has been developed to improve economic conditions and to reduce fishing pressure.
- World production of seaweed in 2019 was over 35 million tonnes.
- North America produced some 23,000 tonnes of wet seaweed in 2019.
Examples of Successful Seaweed Farming
Seaweed farming has been successfully implemented in various parts of the world. For example, in Alaska, Maine, France, and Norway, seaweed production has more than doubled since 2018. These countries have recognized the potential of seaweed farming to improve their economic conditions and reduce their reliance on traditional fishing industries.
