In order to realize a decarbonized society, advancements are being made towards developments in CO2 recovery and carbon regeneration cycles. As a part of that process, technological developments have been made in seaweed cultivation, which utilizes seawater with a high concentration of dissolved CO2. Using this technology, the average yearly production of umi-budo, a characteristic seaweed of Okinawa, increased by about 1.5 times. Furthermore, there are efforts towards developing technologies for fully automated aquaculture and the removal of microplastics by harnessing the power of IoT/AI.

The Ramsar Convention adopted on February 2, 1971, in Ramsar, Iran, is a pioneer in international treaties for environmental conservation. As this was a time before the appearance of the word “sustainability”, the expression “the wise use of” was used. Wetlands, which are the focus of the Convention, are vanishing at a rate three times that of forests despite their being essential in the conservation of biodiversity. It is important that many people understand the benefits which wetlands provide.

The Yamato Museum (Kure Maritime Museum) of Kure City, Hiroshima Prefecture, opened in 2005 with the goal of communicating science and technology that focuses on Kure’s history and shipbuilding. The museum collects and preserves those documents related to the Japanese Navy and Kure City that escaped being destroyed by fire or scattered and lost. As we progress in digitalizing the paper-based archives (pictures, blueprints, written documents), I would like here to introduce details about their preservation and how they are being shared over the internet.
