14 LIFE BELOW WATER

Life Below Water

Life Below Water

As one of the United Nations Sustainable Development Goals, SDG 14 aims to conserve and sustainably use the oceans, seas, and marine resources for sustainable development.
This goal underscores the urgent need to protect marine ecosystems, prevent pollution, and manage ocean resources responsibly to sustain biodiversity and human livelihoods. Universities play a crucial role in advancing marine science, developing sustainable fisheries and aquaculture, and fostering public awareness about the importance of healthy oceans.

Guided by this global goal, Hokkaido University promotes the conservation and sustainable use of marine resources through research, education, and collaboration.
Drawing on its long-standing strength in ocean and fisheries sciences, the University advances research on marine ecosystems, sustainable fisheries, and climate-ocean interactions. Through partnerships with governmental bodies, international organizations, and coastal communities, Hokkaido University supports policy development, innovation in marine technology, and capacity building for ocean sustainability. The University also raises public awareness through outreach programs, museum exhibitions, and educational activities that connect people with the ocean and inspire stewardship of marine life.

  • Comprehensive Agreements with Local Governments

    Hokkaido University has signed comprehensive cooperation agreements with several municipalities including Akkeshi, Fukushima, and Monbetsu. In April 2024, a new three-party agreement with Shiriuchi Town, the Faculty/Graduate School of Fisheries Sciences, and the Field Science Center for Northern Biosphere was established. This partnership expands field-based education, co-creation of coastal resources, and community capacity building in marine conservation.

  • Community Seagrass Meadow Co-creation in Shiriuchi (Reiwa Satoumi Model Project)

    Together with the Water Marine Institute and Shiriuchi Elementary School, we initiated a programme on environmentally adaptive seagrass meadow creation and sustainable restoration. Activities included ocean literacy classes, biodegradable clay workshops using food residues, and collaborative field learning at the Sea Urchin Hatchery Center, a local fisheries hub. These initiatives cultivate community stewardship of shared coastal ecosystems.

  • Community Ocean Literacy & Underwater/Aerial Drone Monitoring (Kikonai & Okushiri)

    Through the Hokusui Drone Research Association, the University conducts hands-on drone observation programmes in Kikonai and joint training with Okushiri High School. These activities build local capacity to monitor coastal conditions, empowering communities to take part in maintaining shared aquatic ecosystems and strengthening community-based ecosystem governance.

Impact

By pairing advanced field science with collaborationg with the local community for shared ecosystem management, Hokkaido University has contributed to improved habitat restoration, such as seagrass meadow recovery, enhanced wetland resilience, and sustainable aquaculture practices. These initiatives have strengthened local governance, promoted environmental education, and ensured that shared aquatic environments remain productive and healthy for future generations.

14.5.5: Watershed management strategy

Overview (2024)

Hokkaido University implements plans to preserve specific diversity of aquatic ecosystems through a comprehensive watershed management strategy.
By integrating scientific research, community collaboration, and long-term monitoring, the university promotes the protection of endangered species, the restoration of natural habitats, and the sustainable use of aquatic resources. These efforts are part of a broader strategy to improve and maintain watershed management, ensuring that management practices are continuously refined to reflect the unique ecological characteristics of each river basin.
Together, these initiatives contribute to biodiversity conservation at both local and regional levels.

Key Initiatives
  • Participation in River Basin Management Committees

    Faculty members serve as chairs and committee members in various river basin management and planning committees, such as the Ishikari River Basin Committee.
