Outline of Final Research Achievements

This study considered strategies to enhance compatibility between mitigating groundwater pollution and promoting the agricultural/livestock industry from both scientific and social perspectives. We investigated spatial and temporal changes in groundwater pollution from the beginning of the problem to the present and investigated stakeholder's awareness and responses to the pollution problem. The following two topics were considered: 1) elucidation of the spatiotemporal structure of pollution, and 2) elucidation of the awareness and response to groundwater pollution. We found that although the supply of nitrogen to groundwater is decreasing, the nitrate concentration remains high in areas near the pollution source. Alongside measures to reduce nitrogen load as people's responses to pollution levels changed, the remaining approaches required to solve the pollution problem were clarified.
