Abstract
We conducted a questionnaire survey and interviews to clarify factors involved in the dumping of garbage at irrigation ponds and possible preventive measures, which involve problems of improvements in the environment for diversified utilization. We surveyed 204 ponds in Kyoto Prefecture; respondents were the farmers in charge of the ponds and the local managers such as representatives of the farmer's association. The main conclusions are as follows:(l) Common preventive measures such as setting up billboards are not effective when this is the only measure taken;(2) Patrol by residents is effective. However, this requires some devices and support to reduce the burden on residents;(3) Principal factors, that encourage the dumping of heavy garbage, are blind spots from residential section, and lack of cleaning and mowing of the area. Dumping might be prevented by removing these factors.
