Stream 3. Healthy Environment

Healthy Environment advances the recognition that human health and environmental health are inseparable. The Stream develops molecular, digital, and field-based tools to monitor biodiversity, assess ecosystem resilience, and anticipate risks to both nature and society. Projects range from pioneering eDNA metabarcoding for coral reefs and eRNA-based biodiversity monitoring of fish, to new approaches for tracking ocean currents, terrestrial ecosystems, and soil microbiomes that link environmental processes to nutrition and human health. These world-first systems not only provide rapid, scalable, and cost-effective monitoring methods but also generate baselines critical for understanding climate impacts on ecosystems. By situating Okinawa as a living laboratory while designing globally transferable protocols, the Stream creates practical pathways for conservation, climate adaptation, and long-term resilience of both ecosystems and communities.
