Research on continued agriculture and rebuilding lives at specific recommended evacuation sites, and the spread of a regional regeneration model

Research grant

Project Description

The project aims to conduct demonstrative research in an integrated manner with resident activities in the Ryozen-Oguni district of Date City, Fukushima Prefecture in order to present a regional regeneration model through continued agriculture and rebuilding lives. Through detailed assessment of the state of contamination through radioactive material (creation of air, soil, and crop contamination maps), the reduction of the air dose and the development of agricultural reconstruction technologies based on the level of contamination, and the construction of a safety inspection system for self-sufficiency and regional distribution of agricultural products aimed at rebuilding lives, the project will establish technologies and scientific knowledge for responding to nuclear power disasters and promote regional regeneration through the assessment of the structure of issues between regions and the social implementation of radiation countermeasures. In addition, the structure of damage will be clarified through systematic damage surveys, and a regional regeneration model will be presented.
