Subcommittee Meetings

Of the eight subcommittees, six have so far met at various times for discussions on moving toward the realization of the Kumejima Model.
    • Development Center Improvement and Planning

      The mission of the Development Center Improvement and Planning Subcommittee is to discuss the needs and seeds required for the Kumejima Model to move “from research to empirical study or even commercialization by the creation of comprehensive plans for realization,” the creation of “a center for research and development,” and “positioning Kumejima as model area for subtropical and tropical regions as a place for both human resource and educational development.”
    • Energy / Demonstration Field

      On July 15, 2014, Kumejima Town, Okinawa was selected by the Cabinet Secretariat Comprehensive Ocean Policy Headquarters as a marine energy (OTEC) demonstration field. In FY2016, tests with the assistance of NEDO are planned for this Field. With such a background, the subcommittee is to discuss the function of the Energy Field and share information on marine energies.
    • Aquaculture

      Through the use of deep seawater, prawn fisheries and sea grape cultivation have already become major industries on Kumejima. Thus the subcommittee with work towards three goals, including “expansion of existing industry (sea grapes and prawns),” “commercialization of demonstrated technologies (aquaculture with deep seawater such as shellfish),” and “demonstration and research of development-stage technologies (biomass, etc.).”
    • Agriculture

      In the agriculture sector, spinach is being grown in the warm seasons through chilled soil technology that is near commercialization. The next step is expanding to the Okinawa market and understanding which crops will feasibly meet the needs of current market situations.
    • Industry

      Compared to power generation, fishery, and agriculture, the manufacturing sector does not rely on large volumes of seawater and thus, does not directly benefit from significantly expanded intake. The focus of this subcommittee is on indirect improvements such as reduced shipping costs, brand improvement, value from 100% renewable energy use, etc. Since future expansion is expected, discussion and the sharing of information to that end will be ongoing.
  • Environment

    The Environment Subcommittee is focusing on the “improvement of environmental conditions through deep seawater use” and the “organization of an environmental impact assessment (EIA) for deep seawater use.” For the environmental improvement side, we discuss the balance of CO2 use from pumping up water and its negation of the need for traditional power for cooling and energy production, evaluate, and study the benefits and concerns of industry use. For the EIA we have conducted an initial examination of the necessary evaluation parameters for expanded water use on Kumejima (via the Kumejima Model) based on existing EIA preparations for thermal power plants. In particular, with respect to the discharge of post-use deep seawater, since there may be higher nutrient or CO2 levels there is a risk of effecting the local ecosystem. We have concluded a quantitative environmental impact assessment is needed.
