This study aims to consider the scale differences and impact of land utilization on milk production costs. The main outcomes are as follows. First, the scale expansion of dairy farming in meadow regions increases the level of concentrated feed and milk production costs. Second, the scale expansion of dairy farming in upland regions reduces the milk yield and increases milk production costs.

Producing feed with high corn silage may be an effective method for stable dairy farming. This study examines the economic effect of feeding high corn silage rations by comparing farmers in a double cropping of corn area and a statistical survey on farm management. There are two farmers who fed corn silage at 36kgFM/cow/day and 30kgFM/cow/day, respectively. Inclusion of a higher amount of corn silage feed increased the net income of the farmers by 11.6% and 7.6%, respectively. This demonstrates the importance of corn production and feeding high corn silage rations for enhancing returns from dairy farming with abandoned farmland.

This study aims to compare the operating efficiency between a large forage harvester system (large machine system) and a compact general-purpose harvest machinery system (small machine system) and consider which systems were chosen by contractors under which conditions. The main outcomes are as follows. According to the analysis of GPS logger data, large forage harvesters have a leg up on the compact general-purpose harvesters in operating efficiency under any field scale. When the total operating exceeds 80ha, the cost of harvesting per 10a with a large machine system is lower than that of a small one.

In this study, I seek to clarify the relationship between farmers’ attributes and their intention to maintain Productive Green Land (PGL) in the city with higher land prices by analyzing a questionnaire survey of farmers in Kawasaki City, Kanagawa, Japan. The following are the results of the analysis. The presence of a successor living in the same household and agricultural sales per area positively affect the intention to maintain PGL. However, land prices of farmers’ residences do not necessarily have a positive effect on the intention to maintain PGL.

The purpose of this paper is to formulate a diversified farming model involving paddy field and upland farming for mountainous areas and to verify empirically the compatibility expansion of farm acreage and increase in income by integer programing. The main outcomes are as follows. First, high added value and labor-saving rice production expands farm acreage and agricultural labourer income. Second, cultivation of forage crops in upland areas expands farm acreage dramatically. Third, labor-saving of vegetable production makes additional income more profitable. This model is the future vision drawn by backcasting approach, so the way of realization should be examined separately.

The objective of this study is to verify the impact of structural change and farmer decision-making on crop varieties by individual data analysis. The main outcomes are as follows. First, the number of cultivars tends to increase with the farm-size to spread the work over a longer planting and harvesting season. Second, in the last five years the planting area by large farmers cultivating many varieties increased. On the other hand, many retired farmers were those who cultivated only one major variety. As the result, the crop varieties in 2017 have diversified compared to those in 2012.

This paper investigated the factors that affect the satisfaction of employees who participated in a food education activity implemented as a corporate social responsibility (CSR) initiative of a major food industry company. For this purpose, we conducted a questionnaire survey of the employees who participated in Kewpie Company’s food education program. Applying an ordered probit model to the data yielded the following findings. (1) Food education under the sales-promotion framework is likely to undermine the satisfaction of participants. (2) High job satisfaction improves the satisfaction of participants. (3) It is possible to raise participants’ satisfaction by encouraging employee loyalty through participation in a food education program.

This study described and compared the actual learning participation and process of three individuals in the Beni-Hoppe strawberry farm, namely the owner-farmer, an experienced farm worker and an inexperienced farm worker. Using daily farm records and personal interviews, Legitimate Peripheral Participation by Lave and Wenger revealed that although commonness on the owner’s instruction at the early working stage was prevalent, differences in improvisations during insect-pest outbreaks and crop growing stage were found. In general, this study found individual improvisations on strawberry as a learning medium and interaction among members of the farm as Community of Practice.

The use of local produce in school lunches is encouraged despite supply limitations especially in urban and suburban areas. We conducted a questionnaire-based survey of farms in Hamura City, Mizuho Town and Nerima Ward, Tokyo, where support systems for the use of local produce in school lunches are limited. Our result shows that delivery labor is correlated with sales, while coordination labor arises independently with sales to school lunch. Most farmers recognize that the distribution efforts are relatively small despite non-negligible working time compared to the sales volume. In the suburban areas, farmers are positive toward increasing their sales quantity to schools, despite the lower price level. On the other hand, farmers closer to the city center are not likely to increase this sales channel even though the price is high. Supporting farm household income, hence, will be important in the suburbs, while increasing local supply will be still difficult in the urban areas.

International prices of cereals in 2019 remain high relative to the level of 2005. This paper examines the influence of the increase in international cereal prices on the Hokkaido and Tofuken livestock industry, based on an inter-regional computable general equilibrium model. The primary outcome of the simulation is as follows. First, an increase in international prices decreases all livestock industry’s quantity of output in Hokkaido and Tofuken. Second, it increases the output of livestock industry in Hokkaido, but decreases that in Tofuken. Third, real output of dairy industry in Tofuken decrease more than the simulation result.

This paper analyzes intra-industry trade of the food processing sector in Thailand and Malaysia using Grubel-Lloyd (GL) indices during 2000–2016. The GL indices for Malaysia are found to be higher than the average GL index for East Asian countries in the same period. On the other hand, the indices for Thailand are lower than the average. The reason is that the GL index for BEC 122 (processed food for household consumption) in Malaysia is high and has a larger trade weight.

The purpose of this study is to develop a simulator named LASTS (the Simulator to be Link Agriculture to Secondary and Tertiary Sectors) and to analyse a case of the chestnut pasta made with chestnuts from Massif des Maures and wheat from Montfuron. Based on mathematical grounds, LASTS is extremely precise. Moreover, it is high versatility. As a result of analysis by LASTS, it is clarified that there is a problem in the primary processing sector of chestnuts. On the other hand, LASTS could quantifically evaluate about a storong point of the case.

The objective of this study is to investigate the formation of “the new middle class” in emerging economies (Thailand and Vietnam). We carried out nationally representative surveys in Thailand and Vietnam based on individuals randomly drawn from the adult population from 18 to 75 in each country. We analyzed the formation of the new middle class in both countries using categorical factor analysis. We could confirm the formation of the new middle classes in both countries, but their attributes are different.
