Stream 3. Healthy Environment

Stream Outline

Healthy Environment directly advances Target 3: Healthy Environment, focusing on the deep interconnections between human well-being and environmental systems. The need for this Stream arises from the recognition that human health and environmental health are mutually reinforcing. It is self-evident that pollution and ecological degradation compromise human health, but less obvious is that broader measures of well-being, including mental resilience and social stability, depend on environmental balance and biodiversity as well. Conversely, environmental health itself relies on resilient communities that are capable of sustaining stewardship, and these communities are in turn built on mentally and phisically healthy individuals.
This circular relationship underpins the importance of the Healthy Environment Stream within the overall program design. While no major restructuring was required compared with the original proposal, several new projects have been added to strengthen the integration of environmental monitoring, ecosystem resilience, and social applications. The Stream thus provides a framework that situates environmental sustainability not as a separate goal but as an integral part of the broader vision of human well-being.

From R&D Leader



Our team measures “environmental health” on land and at sea, contributing to conserving and utilizing ecological resources. Our Environmental DNA (eDNA) technology allows us to understand the corals and fish communities that live there simply by analyzing the DNA present in seawater. So, in the ocean we can monitor changes in the ocean environment. For example, the results can be used to develop policies and guidelines for developing nearby resort hotels. In addition, we will use the scientifically collected data in the terrestrial environment to create educational programs. The program helps understand how natural and human-induced factors affect the environment, and it will promote the conservation and utilization of environmental resources.
