日本政府は，A.I.やロボット技術，ICTを活用して，省力化や高品質生産を実現するスマート農業を推進している．既往研究においても，スマート農業の導入規定因を明らかにする研究など一定の蓄積があるが，重要な要素の1つである「都道府県単位」の「制度」に着目した研究は見られない．そこで，本研究では，スマート農業に関する都道府県の制度（行政計画と補助金）に着目する．都道府県ごとのスマート農機の導入率（用途の異なる10種類）にもとづくクラスタ分析により都道府県を類型化し，各クラスタの特徴を捉えたうえで，土地利用型技術・管理型技術の先進普及グループに属する福井県・茨城県を選定し，両県の制度的特徴について比較的に整理・考察を行う．それらの知見を統合した結果として，都道府県単位の制度と農業新技術導入における新たな仮説を提示する．

気候変動の農業への影響が危惧される中，適応策のひとつである環境ストレス耐性品種の育成・普及について，南アジアの冠水耐性稲を事例に，近年の研究動向を概説する．また，有用遺伝子の供給源となり得る在来種や多様性の保全について，農業の多様性保全サービス支払い（PACS）を中心に研究動向を説明する．環境ストレス耐性品種の普及は，限界地における貧困層の所得向上に貢献する一方，遺伝資源の多様性喪失につながる．多様性は，グローバル公共財として途上国・先進国を問わず，持続的な農業生産に不可欠と考えられることから，今後，遺伝的多様性を評価するとともに，人的活動が与える影響を分野横断的な研究によって調査・分析していくことが求められる．

Given the recent proposal to promote horticultural crops into rice farming in response to declining rice prices and demand, it is important to understand the factors that contribute to the promotion of these crops. Previous studies suggest that the impact of social capital on farming varies with the managers’ attitude, but the impact of social capital on the introduction of horticultural crops and their sales is not clearly defined. Therefore, we conducted a questionnaire survey to determine the impact of social capital on the introduction and sales of horticultural crops in rice farming and the impact of managers’ attitudes on these impacts. The results indicated that social capital has no effect on the introduction of horticultural crops, but has both direct and managers’ attitude-mediated effects on their sales.

The purpose of this paper is to clarify the reasons why agricultural corporations decide to dissolve and how the succession of management resources and the liquidation of debts are affected. To this end, cases of dissolution of arable corporations were investigated. The results of the study revealed that in the dissolution process of agricultural corporations, it is important for the relatives to approach the manager and that the manager takes action to encourage succession to relatives and others. It was also suggested that if smooth succession of management resources and liquidation of liabilities can be carried out, the awareness of maintaining the management of the corporation will decrease for the managers who go out of business, and there will be more room for them to choose the method of dissolution.

The objective of this study was to investigate the relationship between the re-organization of the agreements and efforts to secure human resources under direct payments to farmers in hilly and mountainous areas (DP-FHMA). In Ojiya City, there were re-organizations of the agreements in DP-FHMA in 2017 and 2020. These agreements not only outsourced administrative work but also realized continuous recruitment of new human resources through the outsourcing organization. The foundation of these activities was the relationships that had been established through the past reconstruction from the earthquake. The agreements effectively utilized DP-FHMA and this relationship to solve their issues.

The objective of this study is to elucidate the features of the agricultural land lease market in the Inner Mongolia Autonomous Region by focusing on social relations and geographical characteristics for farmland transactions. The empirical analysis of the data obtained through the intensive farm management survey for 100 households that curentlly utilize both pastoral and arable land has led to the following results. The arable land lease market is underpinned by social ties based on kinship. However, pastoral land leasing is likely motivated by the efficient use of land through its intensification and consolidation and is not related to social ties. In fact, the contribution of the agricultural land lease market to the intensification and consolidation of farmland was confirmed by a comparison of the Gini coefficients of acreage for institutionally allocated and currently managed farmlands as well as by a GIS-based mapping visualization of the central location of both types of households’ farmlands.

The objective of this study is to clarify the awareness and behavior required of farmers to effectively use labor recruitment apps. The conclusions are as follows. First, farmers are required to set working hours that take into consideration the individual circumstances of job seekers. Second, farmers are required to pay more attention to creating a “friendly workplace,” such as by speaking to each job seeker individually while working or during breaks. Third, to avoid a shortage of job seekers during busy periods, farmers are required to make efforts such as recruiting job seekers in public as much as possible.

The purpose of this study is to consider the dissemination and its factors for the new rice variety “Nijino-Kirameki” in Ibaraki Prefecture. All over Japan not only in Ibaraki, “Koshihikari” is the most famous and cropped rice, but recently that share has been decreasing, In the west part of Ibraki Prefecture, the planted acres of new rice variety “Nijino-Kirameki” are expanding. The first reason is its resistance to the rice stripe virus. That virus is proliferating in the west part and causes a reduction in the rice yield. JA promotes converting the rice variety from “Koshihikari” to “Nijino-kirameki.” JA also tries to buy “Nijino-kirameki” at a high price from farmers, and sells hard not only in domestic but also overseas markets as their sales strategy. For those reasons, farmers are converting their rice variety to “Nijino-Kirameki.”

The objective of this study is to clarify how social farming initiatives contribute to promoting general employment, not limited to people with disabilities, but also including those who are socially withdrawn. Upon categorizing the 10 advanced cases, challenges were identified. For the Participant Burden/Self-Financing model, securing funding due to low profitability was a major issue, while for the Public Support Utilization/Disability Welfare Service model, restrictions imposed by existing system frameworks were highlighted. Furthermore, as factors of success, various innovative aspects were observed, which were found to promote psychological readiness for employment.

This study aims to understand the changes in consumer attitudes toward gene-edited foods from providing information and also to examine the factors affecting the attitudes. We used a generalized ordered logit model to compare the difference in the attitudes before and after watching a video that explains gene-edited foods, and the generalized ordered logit model was estimated. The results indicated that the providing information improved consumers’ evaluation of gene-edited food products. In particular, food values such as naturalness, safety and origin, and knowledge acquisition about the difference between gene-edited technology and genetically modified technology played an important role in determining the improvement of consumers’ evaluation.
