What did you create?
Q room is a work that expresses awareness of food production. In recent years, the concept of Social Development Goals (hereinafter referred to as SDGs) announced by the United Nations is spreading in Japan. However, in developed countries such as Japan, it is necessary to increase the food self-efficiency rate due to the declining birthrate and aging population, and a decrease in the labor force. While it is said that the population in the world is expected to reach 10 billion by 2050, no fundamental solution for food production has been proposed. In addition, climate change occurs every year, increasing the damage to farmers. This problem should make us now need to know how and where our foods are coming from. This time, we used a recyclable farming method called Aquaponics to visualize the food production system born in the ecosystem circulation.
Why did you make it?
The reason why we have awareness of food issues that’s difficult to recognize in Japan and communicate through Q room is that we should know how to help each other and survive when an unprecedented situation occurs. This is coming from my experience that I am a refugee who was affected by Hanshin-Awaji Earthquake when I was 2. I spent most of childhood in temporary houses. I had an awareness against natural disaster, but when I was watching the Great East Japan Earthquake on TV, I remembered the word told by my parents and grandparents, “It is important to know how to survive after the disaster”. When I later went to study in the Netherlands, I met a recycling-type food production system that combines aquaculture and hydroponics called aquaponics. I thought I could save myself and others. I think it would be good if I communicate with people through the Q room to raise awareness of food production and make a small step toward the future.
How did you make it?
The base sphere of Aquaponics is all wooden. Each part was cut out with CNC machine from an 18mm thick plywood board, referring to the open source design drawing. Next, the parts were assembled and assembled from the bottom to the top, creating a spherical structure. Q room uses aquaponics to simply express the ecosystem circulation. The system is to break down ammonia into nitrate ions by microorganisms from the fish excrement and organic matter in the middle cylindrical tank. This nutrient water containing nitrate ions can be poured into the planter zone surrounding the sphere to grow vegetables and plants. In order to promote more efficient microbial degradation, a porous stone was installed in the upper stage.
