Title Alternative Geospatial Preference for Asparagus Fields in Thailand
FullText URL fest_022_065_071.pdf

Abstract A questionnaire survey by interview to the farmhouse in Nakhon Pathom Province in Thailand had been carried out, where the asparagus farming as the cash crop have spread rapidly. Valid response from 24 farmers were obtained and Asparagus had been planted in 30 plots within 74 plots (40.5%). As the result of statistical analysis on the geospatial preference for asparagus fields by logit model in which the geospatial characteristics of plots such as elevation, slope, curvature, acreage and distance from farmhouse were adapted as the explanatory variables while the category of the cultivated crops in there was adapted as the independent variable, it became clear that as for the asparagus plots, small lots were more preferred. On the other hand, the geospatial preference for asparagus plots such as elevation, slope, curvature and distance from farmhouse did not became clear.

Title Alternative Evaluation of drop in official air temperature record at Okayama caused by relocation of observation field of Okayama Local Meteorological Observatory - By comparison with records observed at surrounding points -

Abstract Statistical change in official temperature records at Okayama City caused by relocation of meteorological observation field of Meteorological Agency was evaluated. The observation field of Okayama local meteorological observatory was moved to the Tsushima Campus of Okayama University from the downtown area of Okayama City in March, 2015. Comparison between the air temperature records measured at meteorological agency station and the records at Tanjo Pond in Tsushima Campus, showed 0.56 ℃ drop in annual average before and after relocation. Moreover, comparison between the records of Okayama local meteorological observatory and that at the surrounding meteorological observing 9 stations showed 0.55 ℃ drop in annual average. Those results suggest that the relocation dropped annual average of air temperature by about 0.6 ℃.

Title Alternative Method for predicting minimum air temperature in the next morning using local meteorological observation data - Improvement on minimum air temperature forecasting system utilizing the Internet -

Abstract We have developed a minimum air temperature forecasting system using local meteorological observation data in order to prevent or mitigate the frost damage. In this paper, the correlation between the meteorological factors and the decrease in air temperature during the night was shown. Then minimum air temperature was predicted by the multiple regression equation that uses air temperature and humidity at 18:00 as explanatory variables. As the result, the root mean square error (RMSE) was 2.8°C. When the difference of air temperature between 17:00 and 18:00 was used for the prediction instead of humidity, the RMSE was 3.5°C. Next, the prediction was carried out only in clear nights, then the equation that use air temperature and humidity at 18:00 showed that the RMSE was 1.3°C. Although the predictive accuracy of the equations for clear nights is low on cloudy or rainy nights, we can forecast safely on frosty nights by using those equations in combination with the equations for all nights.

Title Alternative Changing Food Production based on Agricultural Enterprises in Tottori Prefecture
FullText URL fest_022_029_054.pdf
Author Ichiminami, Fumikazu|
Abstract The study aims to explain the main features of food production in Tottori prefecture focusing on agricultural enterprises. First, the number of farmers and farm households, the area of cultivated land, and their spatial distribution were analyzed. Then, the production trend on rice, livestock, vegetables such as watermelon and leek, and pears was surveyed. Furthermore, by overlooking the features of each enterprise, food production as a regional agriculture was briefly examined. Farm management in Tottori pref. has long been a small scale selfsufficiency property, but has gradually decayed or specialized. Because agricultural workers are continuously decreasing and aging, farming in Tottori pref. should pay attention to the demand of world food while publicizing a process on food production and farmmanagement carefully.

Abstract At the early stage of this paper, Okayama prefecture was analyzed by the author focusing on the tendency of main sightseeing-areas based on the number of tourists for three decades (Ichiminami, 2002). In this study, the main sightseeing spots in Okayama pref. are also examined and the developments are explained in a more detailed and updated perspective by extending over current features and the number of tourists. One of the important reasons in a significant increase in tourists in Okayama is the opening of the highways, the bullet train and cross-linking of the Seto Ohashi Bridge. At the same time, there are some waves in the increase or decrease of the tourist trends appearing from several vital developments such as environmental, climatic, social, economic and spatial. In this regard, research objectives of the study are mainly based on investigating and making a comprehensive study on main sightseeing spots in Okayama pref. to find new tourism values and to provide a tourism inventory of Okayama pref. by means of information, data and clues from the field in/between the tourist destinations such as hotel guests, gardens and castles. Therefore, Okayama pref. has a rich potential of historical and cultural heritage in terms of spatial planning and growth. The important point is that the structural adaptation between historical and cultural assets and the city life should be provided and protected for domestic and foreign tourism as much as creating better futures in health tourism, gastronomy tourism, cultural tourism, belief tourism, congress tourism, thematic tourism and local tourism.
