The role of Blue Carbon in climate change mitigation and adaptation is an emerging research field. As more data becomes available, stakeholders in policy and the private sector can use it to develop sustainable policies and pioneering climate technologies.
“Seaweed farming offers a scalable, nature-based solution for carbon removal while delivering co-benefits such as biodiversity enhancement, economic opportunities and food security,” said Carlos Duarte, the study’s lead author and Oceans 2050’s Chief Scientist.
The number of seaweed farms around the world is increasing. Seaweed is gaining popularity as food, and is also used in medicines, cosmetics and fertilizers. Around 35 countries worldwide carry out commercial harvesting of seaweed, in water ranging from cold, through temperate to tropical.
As the world grapples with the impacts of excess greenhouse gas emissions, scientists are urgently seeking potential solutions. Moving forward, additional studies are needed to determine carbon accumulation rates worldwide. In support of efforts to contribute to a greater understanding of a global Blue Carbon inventory, the IAEA works to transfer knowledge and build capacity in countries around the world.
