Generally soil-water relations depend upon both the characteristics of retention and the movement of water in soil. Since 1971, the author has done a great deal of research on the theoretical explanation and the experimental testing of the mechanism of water retention and movement in soil. The results are as follows.","PeriodicalId":137099,"journal":{"name":"Journal of irrigation engineering and rural planning","volume":"4 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1900-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128490547","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

{"title":"On International Academic Exchange: In the Spirit of Respect","authors":"T. Sawada","doi":"10.11408/JIERP1982.1982.1","DOIUrl":"https://doi.org/10.11408/JIERP1982.1982.1","url":null,"abstract":"In order to overcome difficulties and keep prospering in the future world, I believe Japan must play a greater international role in the promotion of advancement in scientific and technological fields, and thereby contribute to the welfare of humanity. In particular, much seems to depend on our willingness to cooperate with our fellow countries in Asia and help them in their efforts for economic and scientific development. This cooperation will also be a contribution to the solution of the North-South problem, a problem for all of mankind. Since its foundation fifty-two years ago, the Japanese Society of Irrigation, Drainage and Reclamation Engineering has been making every possible effort to promote international exchange in the appropriate fields of science and technology. During the early decades, this exchange mainly took the form of importing and imitating the achievements of developed countries in Europe and America. During the 1960s, however, Japanese science and technology caught up with those of the developed countries, and since then we have been carrying out original research and have made substantial improvements. Consequently, we are now in a position to offer, in return, as much of our achievements as possible to the countries of the world, so that they may be utilized by all. Since technologies in the field of agricultural engineering are closely related to the natural and social conditions of the regions concerned, special emphasis should be laid on regional studies for successful exchange and improvement of knowledge in this field. Needless to say, regional studies must be conducted in co-operation with the people of the regions concerned. When we engage in cooperative pursuits in foreign countries and endeavor to achieve international understanding in academic and everyday life, I believe the most important thing is to have the spirit of mutual respect for the identity of the various cultural traditions. Customs and traditions differ among different peoples, and indigenous cultures have their own historical backgrounds. There can be no great cultural traditions without the differences characteristic of various races. Therefore, it is to be emphasized again that regional studies should be conducted with the spirit of respect for the cultural identity of different traditions. It is a great pleasure for us all to celebrate the starting of the English magazine of our society, and I personally express my great hope that the Journal will be a forum for significant contributions to the promotion of international academic exchange.","PeriodicalId":137099,"journal":{"name":"Journal of irrigation engineering and rural planning","volume":"93 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1900-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123396792","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

It is very difficult to give a concise definition of rural planning today. The objective of this paper is to provide a realistic interpretation of how rural areas in Japan are changing in order to begin clarifying the future of rural planning. Japan is one of the most densely inhabited countries in the world. The country is mountainous and covered with forested areas which are too steep to develop. Relatively flat lands have been used for agriculture intensively. Japanese agricultural history is very long: rice cultivation started about two thousand years ago.","PeriodicalId":137099,"journal":{"name":"Journal of irrigation engineering and rural planning","volume":"32 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1900-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123523488","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

While total imports of agricultural products reached a total value of approximately 4.05 trillion in 1991, making this country the world's largest net importer of agricultural products, Japan's self-sufficiency in food has been dropping steadily since 1960. In 1991 Japan satisfied only 46% of its people's total calorific intake from domestic production, with self-sufficiency in cereals a mere 29%. Japan is the only country with a population of over 20 million people which has a calorific self-sufficiency of less than 50%, and is well below the average self-sufficiency for both industrially advanced countries (110%) and developing countries (90%). In fact, Japan was ranked 136th in terms of self-sufficiency among the 155 countries listed in FAO statistics for 1980, with Hong Kong, Singapore, Brunei and Macao being the only countries in Asia to rank lower than Japan. The fact that Japan alone has such a low level of self-sufficiency among the industrially advanced countries indicates that industrial growth is not necessarily accompanied by a decline in agriculture under a capitalist economy. The trend in Britain, where the calorific self-sufficiency ratio grew annually from 48% in 1970 to 73% in 1988, when self-sufficiency in cereals was over 100%, has been quite the opposite to that in Japan. Neither is Japan's low level of self-sufficiency a result of low productivity due to lack of suitable farmland and other natural constraints . This is clearly borne out, for example, by the fact that total wheat production was","PeriodicalId":137099,"journal":{"name":"Journal of irrigation engineering and rural planning","volume":"13 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1900-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121648287","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
