要旨
The basis of Japan's irrigation management system is a representative, multilayered organization based on local communities, or hamlets (mura) like those of the Edo period, in which farmers can participate in the voting process for land improvement districts. This system allows farmers to mutually coordinate regional conflicts over irrigation, and is a social technology and system that enables the realization of national goals. In recent years, farming patterns have become larger and more corporate, and there is a need to reconstruct an efficient irrigation management system in response to changes in the water management entities of agricultural water use facilities. In particular, labor-saving irrigation management by a small number of farmers is an important issue that is essential in considering the next generation water management system. In this study, a low-cost remote monitoring system using security cameras was installed in a trunk canal at a small land improvement district in Fukushima Prefecture, Japan, and the possibility that the land improvement district in charge of maintenance and management could operate and manage the system was examined. As a result, while the remote monitoring system was found to be effective in saving labor for waterway management, it was considered necessary to consider the daily activities of land improvement district staff when introducing the system. In addition, the running cost required to deal with and maintain the system in case of breakdowns is an important item, and it is considered necessary to devise ways to reduce communication fees in the future.
