Outline of Research at the Start

This study will assess the ability of seaweed farms to capture carbon and examine their potential as Blue Carbon ecosystems. The productivity of these farms will be compared to natural seaweed and seagrass ecosystems.

Outline of Final Research Achievements

Carbon dioxide concentrations are steadily increasing and is leading the increase in global temperatures. In turn, seawater temperature is increasing and changes to the seawater temperatures affect the marine ecosystem. On way to minimize the effect of increasing carbon dioxide concentrations is through mitigation, in other words by removing carbon dioxide.

In this study, we assessed the ability of seaweed farms to capture carbon and examined their potential to serve as blue carbon ecosystems. We examined seaweed farms at three sites. One was a mozuku aquaculture farm in Okinawa, and the remaining two were wakame aquaculture farms in Miyagi. We compared these farms to natural ecosystems in Nagasaki. We show that the cultivated species and location of the farms influence the potential of seaweed farms ability to capture carbon, and we show that variations among farms and species were also great. This study has added much insight into how seaweed farms can act as blue carbon ecosystems.

Academic Significance and Societal Importance of the Research Achievements

炭素隔離は、気候変動緩和のための重要なプロセスである。特に、自然を利用した吸収は、環境保全と食料安全保障を促進するために、魅力的な戦略である。本研究の成果は、海藻養殖場や海藻生態系による炭素隔離の能力を明らかにし、海藻生産と生態系保護への取り組みにつながると期待される。
