Understanding the state of consensus formation regarding the use of coastal sea areas in Iwate prefecture and dividing sea areas by ecosystem

Research grant

Project Description

Marine spatial plans are comprehensive plans for using sea areas that are formulated through discussions between stakeholders that use these areas and are an effective way of conserving seas and making the use of various marine resources sustainable. As of 2017, they had been introduced into 65 countries around the world. However, although they were referenced in Japan's Third Basic Plan on Ocean Policy, they have yet to be introduced in Japan. As a step toward implementing a marine spatial plan, this research aims to understand the status of consensus formation regarding the use of sea areas in Iwate prefecture in light of considerations concerning the installation of offshore wind turbines in coastal areas. It will also compare and analyze the division of sea areas based on methods including scientific surveys of current seas areas in order to contribute to incorporating expert natural science perspectives into the realization of the marine spatial plan.

Research record
  • Working on observational and numerical modeling of the structure and fluctuation mechanisms of oceanic vortices and fronts, as well as their impact on ecosystems.
  • Carrying out quantitative experiments and on-site sampling in order to discern the way ocean currents affect the transportation, growth, and survivability of fish egg hatchings from the perspective of connecting fisheries and oceans.
  • Conducting direct observation of seawater exchange as well as intensive surveying of shelf tides, focusing on the rich and diverse marine environment surrounding Sanriku Coast.
  • Having experience in researching and actualizing responsible appropriation of marine resources, this endeavor will seek to grapple with the issue of connecting literature with solutions for the coastal areas at hand.
