My DreamTo reveal the hidden mechanism of the rural ecosystem underpinning the abundant nature in Japan.
ThemeThe study on the relationship between human disturbance related to agricultural activity and the species living in agricultural fields
Instructable research topic for doctoral thesis
|License||Professional Engineer trainee, Land Surveyor trainee|
I was born and raised in Fukuoka prefecture in Japan. Although most of my researches and jobs were related to the eingineering field, my Ph.D thesis was about ecological engineering. With involving in agricultural civil engineering, my research focuses on the species living in the paddy field, rural area, and so on.

Island ecology is known worldwide as a biodiversity hotspot. Naturally, Japan is one of these islands. The number of endemic species that can be seen only in Japan surpasses those of the US or the European continent (e.g., amphibians and reptiles). What supports the richness of the Japanese ecosystem is that what we call “the Land of Abundant Reed Plains and Rice Fields”, the rural and agricultural environment created and protected by our ancestors. It is not a virgin-state-nature, but a fertile ecosystem created by the human hands, where the balance between human activities and the survival of plants and animals existed.
However, the post-WWII energy revolution and the declining birthrate and an aging population have exhausted rural society itself, and at the same time, biodiversity has been rapidly disappearing. The investment in infrastructure aiming to recover the exhausted rural communities has led to a vicious cycle of further deterioration of the species habitat. As a result, the once harmonious relationship between humans and plants has turned hostile.
We will research to clarify the actual conditions of the organisms that live in rural societies and find a way to coexist with us once again.
