On July 11, 2026, researchers at Kyushu University are leveraging local wisdom and scientific methods to manage water resources in Fukuoka Prefecture, Japan. The project aims to restore abandoned rice fields into thriving wetlands and forest habitats, enhancing biodiversity and community engagement.
Community-Centric Water Management Initiatives
The efforts led by Hironori Hayashi and Yuichi Kano focus on integrating education with community participation. Their project, titled "Community-led nature positive restoration at watershed scale in a biodiversity hotspot of Japan," is one of four projects globally recognized by the National Geographic Society's World Freshwater Initiative.
Hayashi recalls how local residents offered their abandoned farmland, excited by the project's potential. "Originally, the residents sympathized with our approach and offered us their abandoned farmland," he said. This collaboration highlights the importance of community involvement in environmental restoration.
Historical Techniques and Modern Science
The region of Akizuki is notable for its traditional river engineering methods, known as Ishidatamizeki, which date back to the Edo period. These stone channels have been quantitatively assessed for their effectiveness in managing flood energy. Hayashi has dedicated nearly 15 years to the conservation of these historic structures, recognizing their value in contemporary water management.
Both researchers have witnessed the challenges facing local ecosystems. They aim to improve groundwater recharge and minimize flooding risks through their restoration efforts. Kano, who specializes in freshwater fish, emphasizes the significance of sustaining river ecosystems that support local agriculture.
Engaging the Next Generation in Environmental Science
A key aspect of the project is engaging local communities, particularly children, in scientific exploration. Hayashi and his team invite residents to participate in fieldwork, fostering a connection between the community and the natural environment. This hands-on approach allows young participants to learn about local biodiversity, such as the Japanese toad, during nighttime surveys.
One notable partner in this initiative is Kyusuke Takaki, a 10th-generation craftsman from Akizuki. His family has lived in the area since 1819, and he expressed surprise at the biodiversity present in the Notori River basin, which supports nine of Kyushu Island's ten frog species. Takaki's involvement underscores the potential for local knowledge to enhance scientific research.
