Since the implementation of feed in tariffs (FIT: a subsidy policy to promote the spread of renewable energy), the external diseconomies of solar panels installed in excess, to earn income from the sale of electricity from photovoltaic power generation, have become apparent. The purpose of this study, therefore, is to identify the impact of the installation of photovoltaic power generation facilities on the living space of citizens. Using data collected through a web survey of residents living in five prefectures in the north-eastern Kanto region of Japan, a spatial autocorrelation analysis was conducted to identify the spatial distribution of discomfort caused by photovoltaic power generation facilities. The results clearly indicated that the spatial discomfort of these residents living in clusters, increased with the installation of the solar panels in their living space. Some of the residents intend making radical demands for corporate action to alleviate their discomfort; such actions can lead to environmental conflict. The results demonstrate that radical solutions are necessary to reduce the spread of this discomfort. By further utilizing the data obtained in this study, it will be possible to estimate the regions at risk of solar panel-related conflict more objectively.

We examined the possibility that residents who experience severe natural disasters such as typhoons can subsequently develop increased positive feelings toward the place where they live. Accordingly, we surveyed Japanese residents about their place attachment before and after Typhoon No. 19 in 2019 by comparing the perceptions of mandatory evacuation-order area residents with those of other area residents. The data were collected from 11,799 residents from all over Japan via a web-based questionnaire survey conducted in November 2019, immediately after the October 2019 typhoon. The results indicated that place attachment improved significantly among residents of underpopulated mandatory evacuation-order areas. We hypothesized that social capital unique to rural areas was a factor in this improvement, but the exact causal relationship has not been identified. The next task is to test this hypothesis, which may contribute to the development of a disaster resilience theory that is specific to rural areas.

The hypothesis of the beneficial effects of agricultural activities on the maintenance of positive health conditions has been empirically tested using several data sets. However, the association between good health and agricultural activities has not been examined across a wide geographical area, and no convincing census has yet been obtained. This study used big data to test the hypothesis. Medical receipt data, which represent a form of big anonymous data, were used as objective indicators of health conditions. The extent of agricultural activities conducted in particular regions was estimated from the census of agriculture and forestry, and comparisons were then affected by the health conditions of the specified areas. The use of medical receipt data is restricted because such data can directly indicate the health conditions of individual residents. This study set the unit of analysis as multiple neighboring cities and towns to avoid constraints on data use. The analysis results revealed that the reduction of agricultural activity paralleled the deterioration of health conditions in some regions. However, the study did not confirm the overall apparent effects of agricultural activity on the amelioration or deterioration of health conditions. More determinate knowledge may be attained by separately reviewing the data on agricultural activities and health and by extending the period of data collection.

Land consolidation (LC) is implemented as a public project that contributes to the improvement of agricultural productivity, and its effect is evaluated mainly by labour productivity and land productivity. However, to maintain both agricultural production and the social community, understanding the impact on non-farmers in the community as one of the aspects of LC is extremely important. In this study, we surveyed rural areas about eight years after the LC was implemented by posted questionnaire and analysed the difference between farmers' and non-farmers' perceptions of the multifaceted evaluation items on the policy effect. The evaluation points for the LC include the following: [1] Impact on farming and farmland preservation, [2] Impact on community activation, and [3] Impact on collaboration between farmers and non-farmers. Results can be summarized as follows: First, it was confirmed that there is a trend for non-farmers' attachment to the area to be reduced because of LC. Second, non-farmers evaluations that LC attracts young farmers were also low. However, this opinion was much more noticeable in non-farmers who had quit agriculture recently than in the generation that had left agriculture because of LC. In other words, LC is a useful policy for improving agricultural conditions and agricultural structure. However, in some cases, the connections between farmers and non-farmers is weakened. Thus, cooperative activities to actively prevent this weakening are important.
