Abstract
Various kinds of knowledge are hiding in scenes such as farming, daily life, resource management, organizational activities etc. in rural areas. A huge amount of tacit knowledge has been dispersing silently by the retirements of elderly persons. Recently, the importance of local knowledge came to be recognized widely among the people. Because the local knowledge is intangible, it is still a difficult problem to identify it. In this article, we try to grasp the knowledge structure on farm pond management using questionnaire survey data with a clue of the previous researches that structured the tacit knowledge in the field of business management. Based on the difference of knowledge possession among the statuses in irrigation associations, we discuss a problem of intergenerational transfer of the knowledge.
