ジャーナル フリーThe authors intend to develop the environmental education in using the urban heat island as one of very poular phenomena observed in most of the cities in Japan and the world. In this study, they consider that the purpose of the enviroumental education is to bring up ervironmental ethics according to the understanding of physical system. The meaning of bringing up the environmental ethics is recognized as educating the way of thinking for the better environmental creation from the viewpoint of environmental conservation. Learning by the experience is one of the best ways in of education to understand physical environmental system. For this purpose, the urban heat island phenomena can be considered to be a very good example because about three quaters of Japanese people are living in the urbanized area.
The understanding of physical system means the understanding of earth's radiative equilibrium because solar energy is the only one energy that the earth receive within the solar system. In other words, it is to recognize the radiation balance and heat balance (the concept of net radiation) of the earth-atomspheric system. Therefore, in this study, more global physical system, the solar-earh system, is applied for the fundamental system instead of the ecosystem which has been accepted for Japanese environmental problems.
In recent years, the most serious problem for human physical environment, in other words, the disruption of the system, is the thermal pollution because most of the energy used by human activities are released for the space ultimately as the heat. Those activities occur within the urbanized area intensively and develop the urban heat island phenomena as one of the typical thermal pollution.
People intend to keep their active physical environment from the thermal pollution because its system is suitable for them. This means that they intend to continue earth's active radiation equilibrium. Therefore, the authors concluded that the urban heat island phenomena was the one of the best teaching subjects for the environmental education both for the the understanding of the system and for the learning by experience.抄録全体を表示PDF形式でダウンロード (1016K) -

ジャーナル フリーIn the Mayama district of Shimonita-machi, the traditional type of agriculture was a combination of rice, barley, wheat, sweet potatoes, and cocoon production. These crops were grown on the river terraces and gentle slopes. In this type of farm management, Welsh onion growing was only supplementary to cash cropping. This traditional type of farm management have changed into a new and more intensive one due to the decline of sericulture and wheat and barley production, the instability of konjak market price and the acreage allotment of rice production. Farmers have reduced self-support crops, and have introduced commercial crops. Thus a new type of farm management have developed which combines welsh onion with konjak and shiitake production.
Welsh onion growing has been developed with demand for year-end gifts and of major restaurants. Additionaly, the yield of welsh onion is 670 thousand yen per 10 are, about three times as high as yield of konjak and cocoon, and about fourteen times as high as yield of rice. Therefore, welsh onion growing is main commercial farming in the compound management of agriculture in the district. Although welsh onion growing is labor intensive farming, farms can decide the size of welsh onion growing according to available labor force in their family, and they can obtain higher returns from small scale of operation. Furthermore, a distribution network of welsh onion has traditionaly been maintained by each farmer, so that welsh onion has been grown by both full-time farmers and part-time farmers.
Eventually, welsh onion growing promotes not only the viable agriculture in the Mayama district of Shimonita-machi, but also plays an important role in retaining cash crop farming of part-time farmers.抄録全体を表示PDF形式でダウンロード (4006K) -

ジャーナル フリーAccording to the improvement of local airports, transportation capacity by the jumbo jet airplane service has greatly increased. Around local airports, we can find some new high technological factories and also new agricultural regions using air transportation.
The aim of this paper is to examine how the agricultural region of chrysanthemums production using air transport has been formed and what regional conditions exist in this area.
The characteristics of agricultural region as the result of the case study in Kamotocho, Kumamoto Prefecture, are summarized as follows.
1) Before the introduction of chrysanthemums production, the charactor of the agricultural management in Kamoto-cho indicated the combination type of rice and melon in a year. By the implementation of Paddy Field Reorganization Policy, paddy field changed to be used chrysanthemums production instead of rice. So the charactor of agricultural management in Kamoto-cho changed to indicate the production system of melon and chrysanthemum in a year. Recently we can find the diversification of farmers who produce many types of chrysanthemums.
2) Kamoto-cho is located in about one hour distance by car from Kumamoto Airport. In 1975, it began the jumbo jet airplane service to Tokyo and other large cities, so the air transportation of chrysanthmum to Tokyo was increased. During the Period of the depressed production near Tokyo metropolitan area, Kamoto kept the steady supplier of the chrysanthemum in Tokyo market.
3) In order to examine the formation of chrysanthemums production area using air transport, we must consider not only the accessibility of airport and the air transportation system such as market factors, but also the regional conditions and the agricultural managements of the agricultural area. So, its formation process consist of the complex organic factors.抄録全体を表示PDF形式でダウンロード (2349K) -
