- Visualization of expertise of expert administrators -

The Institute of Rural Engineering, NARO (NIRE) has developed an "irrigation facility management ledger system" that can record and refer to the management know-how of agricultural water users' facilities such as division gate, open channel etc. on the map. By constructing a database using this system, records of management know-how and aging situation of facilities, as well as natural disasters such as guerrilla rainstorms etc. can be recorded and used for daily management and as reference in the future. The system can be easily operated by recording actual conditions of the site with photos and memos using mobile devices or by input of information in a ledger format, and can be used efficiently in a small scale land improvement district where it is difficult to transfer the know-how in management.


  1. In agricultural irrigation facilities such as irrigation canals, it has become difficult to transfer the management know-how for future use due to the aging of staff members who are responsible for daily maintenance and management, such as observation of water level and adjustment of water distribution.
  2. Therefore, the Institute of Rural Engineering, NARO has developed the "water management facility management ledger system" that records the know-how on management of agricultural irrigation facilities and daily management logs that can be referred to on the map.
  3. In this system, the condition of the agricultural irrigation facility on a specific site is recorded as a photo, voice or memo with location in a mobile device application, which is then sent via e-mail, automatically registered in the office computer, and checked on the map.
  4. In addition, the information received from the mobile device can be organized in a ledger format on the personal computer and compiled into a database. This data can be accessed using commercially available spreadsheet software and can be confirmed on mobile devices.
  5. With this system, it is possible to refer to the establishment year of the facility in order to plan a repair or renewal of the facility, or to transfer the know-how in facility management the land improvement district has to the next generation. It can be used for management of agricultural irrigation facilities essential for agricultural production.
  6. An on-site demonstration is being conducted and this system will be made available at a cost of around 50,000 yen in the current fiscal year.
