Research on area rehabilitation and regeneration from radioactive material by means of recycling-orientated agriculture in areas of Nakadori and Hamadori, Fukushima Prefecture

Research grant

Project Description

Study on radiation dose estimation for safe farming in Nihonmatsu City, Towa-Cho; Iitate Village and Minamisoma City in Fukushima Prefecture. This project is striving for a sustained reconstructive process to aid local recovery and regeneration, with the aim of helping the renewal of farmer's and their desire to return to the area. The research on the recovery of communities is based on safe environmentally friendly recycling agriculture done by independent farmers, and researchers from Niigata, Fukushima, Ibaraki, Yokohama National University, and Tohoku University are working with these local farmers to implement contributions to this recovery. The research includes radioactivity reduction in forests, farm land, water and crops, resource recycling, and resource recycling-orientated agriculture.

Research record
  • Since May 2011, participated in the Yuki no Touwa project, and from April 2012, started reconstruction research as a representative from the Mitsui Environmental Fund (reconstruction research grant) on "A proposal of measures to reduce radiocesium and its movement from undeveloped woodland to water, agricultural soil, produce, and food." In May 2012, began agricultural reconstruction research in Minamisoma City with a discretionary grant from Niigata University's President. After this, began investigatory research into the requests from farmers in outer and inner districts of Iitate village district, which began from August 2013.
