The purpose of this study was to examine how to coexist with black bears in Ishikawa Prefecture, where a record number of black bears appeared in the autumn of 2020, and to understand the current risk perception and coping behavior of prefectural residents, which could serve as a basis for the formation of a coexisting society. In line with the studyʼs objectives, we conducted a questionnaire survey using LINE, which has a high penetration rate, to conduct efficient sampling in rural areas where it is not easy to collect data according to regional characteristics and resident attributes. The survey was conducted in February 2021, with a sample size of 1,742 valid responses from the entire prefecture. Analysis of the obtained data showed that citizensʼ risk perception of bear encounters was increased by the occurrence of bears in their living areas and their experiences of encountering bears. Residents who had bear encounters in their living areas relied on various information sources, had higher knowledge, and took actual encounter avoidance actions when they had experienced encounters. Information communication is needed to stimulate more encounter avoidance behavior, for example, by communicating standards of real encounters.

We extracted the communities located in the coastal area and clarified the characteristics of them using the 2015 Agriculture and Forestry Census data and the results of the national census, taking Ehime Prefecture as an example. We categorized them used the employment rate data by industry and analyzed the agricultural area types of the communities included in each type. As a result, of the total 3,284 communities, 628 (19%) were coastal communities, and 23% (340,000) of the population lived there. In addition, from the viewpoint of agricultural area type, it was found that the ratio of hilly agricultural areas is high and agricultural land is often used as upland in coastal communities. As a result of cluster analysis using the ratio of employees by occupation as a variable, coastal communities were classified into 6 clusters. As a result, it was found that in the coastal area, mountainous agricultural communities are areas where fishing industry is thriving, and flatland agricultural communities are mostly citrus-cultivated areas using slopes. The high proportion of hilly agricultural communities is due to the development of relatively large orchards and the narrowness of the forests found on the islands and peninsulas. As a result, the number of communities not included in the mountainous agricultural area increases due to the increase in the cultivated land ratio or the decrease in the forest field ratio. Furthermore, it was found that many communities specializing in primary industry are in areas with high geographical isolation, and that the number of workers per community is small in these communities.

We developed and executed a management plan for the extermination of the invasive turtle Trachemys scripta elegans in a closed water body as a case study in the moats of Sasayama Castle, Tanbasasayama City, Hyogo Prefecture. We captured turtles using 150 traps baited with fish during 11 trapping intervals between July 2015 and September 2015, for a total of 1650 trap nights. We used the number of individuals caught per trap (Catch per Unit Effort, CPUE) as a measure of removal effectiveness and found that the CPUE of the baited traps decreased from 1.10 to 0.10 by the end of trapping in 2015. Since 2016, we used two types of traps, baited traps and basking traps, the latter designed to take advantage of basking behavior. The median CPUE of basking trapswas 1.15, whereas the median CPUE of baited traps was 0.15, indicating that the basking traps were more effective even when baited traps were present. We captured significantly more females than males with baited traps (Chi-squared test, p<0.05), while basking traps used in conjunction with baited traps captured more juveniles (plastron length less than 50 mm) than the total number of individuals captured by basking traps. These findings suggest that for the effective removal of T. s. elegans, it is important to use a combination of different trapping methods.

Less developed rural China has been suffering from aging cadres for decades, while college graduates are facing serious employment pressure. Based on this situation, the Shandong provincial government initiated the Selected College Student Village Officials (SCSVO) project, establishing a labour circulation system between rural and urban areas for college students. However, the number of SCSVO students is growing extremely slowly, and there is a demand for more participants. Therefore, this study clarifies the key factors that influence college studentsʼ willingness to be candidates for SCSVO. This research highlights the target characteristics of potential SCSVO candidates and provides a direction for the further development of the current SCSVO project. It applies a binary logistic regression on original data collected through questionnaires and interviews. The results reveal that (1) 37% of the respondents are willing to join the SCSVO. (2) Students with the following objective factors are more likely to join the SCSVO: younger, male, majoring in education/agronomy/medicine, personal positive impression towards rural areas, cultural-difference tolerance, and consideration of parental attitudes; these factors have significant effects on studentsʼ willingness to join. (3) For the further development of the SCSVO project, the government and SCSVO-related organisations should further disseminate the attractiveness of rural locations, such as the low-stress working conditions and natural environment.

Land fragmentation is a major obstacle to agricultural productivity improvement in Japan. Land Consolidation Banks (LCBs), which were established in each prefecture of Japan in 2014, aim to facilitate land consolidation and reduce land fragmentation. Many qualitative studies have been conducted to evaluate the performance of LCBs. However, few papers shed empirical light on the relationship between land fragmentation and LCBs due to the lack of adequate data. In this paper, we have created data from a large sample of farm plots in Hyogo Prefecture, processing these data using GIS software to calculate the degree of land fragmentation and quantitatively clarify the effects of the LCB in the prefecture on the improvement of land consolidation. The farmland plot data was created in the following manner : Data from the “Agricultural Land Information System” was collected using the web scraping method, these data then being attached to cadaster data in the targeted areas. The large sample of farmersʼ plots revealed that farmers who cultivate relatively large areas of farmland in the targeted areas had succeeded in enlarging their average plot size but had not succeeded in reducing the distance between plots. In addition, we applied propensity score matching to evaluate the impacts of the LCB in Hyogo Prefecture on the enlargement of farm size and on the reduction of land fragmentation. The econometric analysis based on community level data showed that the LCB has contributed to the transfer of farmland but has not contributed to the consolidation of spatially dispersed plots.
