An excellent tip for a lifestyle that integrates with the environment can find in greenhouse agriculture. Farmers sleep in the greenhouse during their initial training. If the temperature and humidity are uncomfortable for them when they sleep, it is also painful for the vegetables, and they need to adjust their conditions. In other words, a better environment for plants and a better environment for humans. We will create an ark that can n-fold Arktecture (Ark + Technology + Culture). This next-generation ark combines underwater architecture and salt-resistant technology to unite human life, the natural environment, and various living things and create a world where we can live better in the age of climate change. The first step in this process is the prototyping of "Green Ocean," a floating farm.
Salt-resistant architecture technology
The Green Ocean floats on the coast. It creates two greens in the space above and below the sea. A farm produces the green at sea for food production using saline agriculture technology. The other is a green that aims to improve the underwater environment by cultivating algae and other plants under the sea surface. The architectural materials will be designed from thinned wood, and the wood joints will be carbon joints for salt resistance. The floating facilities are to increase buoyancy with a special coating. The characteristic shape of the roof is to capture rainwater efficiently. By mixing rainwater and seawater, ph adjustment and dilution rate adjustment will complete. It will become fertilizer for saline agriculture. Also, the cold seawater controls the indoor temperature by its stable temperature. It uses it as air conditioning on the farm.
Seawater farming technology
CULTIVERA, a partner startup that researches and develops seawater farming technology, runs Pomona Farm spontaneously, an agricultural corporation that has expanded to 10,000 square meters in Mie Prefecture. The core technology is "Moisculture," a humidity-controlled cultivation technology that reproduces the natural soil surface layer of about 15 cm using special fibers of 5 mm in diameter. It is possible to grow vegetables with enhanced sugar content and vitamins. Moisculture requires only one-tenth of the amount of water used in conventional irrigation farming. It is a cultivation technology that can apply even in areas where water is not abundant.
Application to Seawater Agriculture
Seawater agriculture is a new technology based on moisiculture. Alkaline seawater and acidic rainwater are mixed and neutralized, and various types of roots are cultivated according to the variety to absorb water and nutrients from the ground and air. As a result, they grow into functional vegetables that can utilize the minerals and nutrients contained in seawater.
*Joint patent application is proceeding.
Underwater Environment Improvement
Phytoplankton produces primary nutrition by photosynthesis. And seaweed circulates the ecosystem in shallow seas (tidal flats, rocky shores, and beaches). Still, this essential production is decreasing due to environmental deterioration, affecting fisheries. However, this primary production is declining due to environmental degradation, which affects fisheries — conceptual stage.
The expansion of offshore farms will strengthen the autonomous ecosystem, and n-fold it acquires various functions and respond flexibly to challenges.
The agri-tech R&D company of Shohei Toyonaga, which operates Pomona Farm, a 10,000 square meter agricultural corporation in Taki Town, Mie Prefecture. He is in charge of seawater farming technology and vegetable type development.
He was born in Aichi Prefecture in 1989 and worked in the archaeology laboratory at Waseda University. He was dedicated to the excavation of Cambodian ruins and the preservation of landscape and culture. In 2016, he founded Cultivera LLC. While researching and developing various agricultural technologies using his own patented Moisculture technology as a platform, he is also running his agricultural corporation, PomonaFarm, in Taki-cho, Mie Prefecture.
