🚨🌊A marine research team led by Professor Yan Qingyun has proposed a method "to assess the net #CarbonSink of marine #macroalgae (Gracilaria) cultivation. Then, they computed net C sink of Gracilaria cultivation in China based on Gracilaria's annual yield in the last 10yr."
🧵

Also, "the net #CarbonSink trend of #Gracilaria cultivation in the next ten years was predicted by the autoregressive integrated moving average model (ARIMA)."

Finally, researchers "explored the potential #CarbonSink increase and methane reduction related to #Gracilaria cultivation in China through a scenario analysis."

Their results suggested that "the net #CarbonSink of #Gracilaria cultivation in China was about 32.1-92.4 kilotons per year from 2011 to 2020, and showed a great annual growth trend."

Specifically, "the predicted average annual net #CarbonSink of Gracilaria cultivation from 2021 to 2030 would double that of the last ten years (i.e., increase to 77.8-191.4 kilotons per year)."
5/9

Thus, "the Gracilaria cultivation could contribute largely to the attainment of China's C peak goal. Moreover, under a scenario of yielding ruminant green feed with extra Gracilaria cultivation, each ton of #macroalgae was implied to lower C emission (CH4) by 0.33-0.68 tons."

IN SUMMARY:
"Marine #macroalgae cultivation (MMC) might form a synergistic chain of "#CarbonSink increase-H2O purification-economy-CH4 reduction." A synergistic new model that operates through MMC, economic aquaculture & green feed production" was proposed in this study.
