Abstract
The transitions of biodiversity policies in national environmental policies and/or of the influence of national trends on local plans have been clarified by the other previous researches gradually. However, recently many local governments have been discussing local biodiversity strategies based on Japan’s Basic Law on Diversity. In order to consider effectual quantitative information for biological diversity policy at the local government level, this study focused on extracting quantitative information used in basic environmental initiatives by local governments including all of cities designated by government ordinance, which could indicate the natural environment, and examining its characteristics and roles. As a result, it was clarified that many local governments set numerical targets for a large number of policies, and indicated concrete administrative action for the future. On the other hand, the information on the state of the environment for policy evaluation was limited, and the policies had not reached a stage where evaluation was possible on how they contributed to maintaining the environment. Also, it was suggested that the effectual quantitative information could be different by the space scale of each plan for nature conservation.
