This study in Nature Food claims that widespread efforts to sequester carbon on agricultural land could offer farmers around the world extra income and allow net zero emissions in agriculture by 2050 for a lower cost than other options. To achieve this, the study argues that it requires deploying highly efficient institutions and monitoring systems across the world in the next five years. 

Seaweed is an overlooked, but highly versatile climate solution, says Forbes in its coverage of a new study by investors. The article highlights the numerous co-benefits of seaweed; it’s a low-carbon food crop that requires few inputs, it has the potential to replace fossil fuel-derived plastics, and, the article even touts the crop as “the largest carbon sinks in the world”, although research disputes this claim. 

Seaweed farming is being championed as a magic bullet for food systems and the environment, promising to capture carbon, rehabilitate ecosystems and feed the world. Recent reporting from the Guardian investigates one seaweed enterprise, the Climate Foundation, and its mission to win Elon Musk’s $100m Xprize.
