The Institute for Rural Engineering, NARO (NIRE) aims to promote agricultural innovations with the development of technology that contributes to the achievement of a policy of "rural promotion" through prudent management of agricultural water and soil. Our recent research focuses on the development of technology that contributes to strategic renewal and management of agricultural irrigation facilities, disaster prevention and reduction in rural areas, preservation of regional resources for agricultural production, advanced paddy field management, biomass utilization, measures against the effects of climate change on farmland and water resources, and sophisticated environmental control of agricultural structures as well as many other areas. Moreover, we provide technical assistance with hazard and disaster countermeasures for farmland and agricultural facilities.
Heat exchange efficiency of the heat pump is highly improved by installation of sheet type heat exchanger in a water flow
NARO has revealed that installing a sheet type heat exchanger in a water flow such as agricultural irrigation canals can exchange heat approximately 15 times more efficiently than installing it underground. Agricultural irrigation canals widely used in rural areas can be effectively used as heat sources for heat pumps by this research result. It also helps to reduce the consumption of energy for cooling and heating of greenhouses and its operational costs. Read more
Smartphone version of Disaster prevention support system for irrigation pond
We have developed "Smartphone version of disaster prevention support system for irrigation pond", which is a new user interface of "Disaster prevention support system for irrigation pond" published in September 2018. It is now possible to report damage status while inspecting the risk information on the pond, thereby enabling the rapid sharing of disaster information of irrigation ponds. Currently, user IDs are distributed to prefectures and municipalities nationwide, and they are being used on a trial basis. Read more
Labor saving water sampling method for groundwater dating
NARO has developed a technique to collect groundwater in a labor-saving manner using a commercially available water sampler for wells in order to measure the age of groundwater. In the dating method with the concentration of sulfur hexafluoride (SF6) as an index, which is a dissolved gas in groundwater, the time required for sampling can be reduced by up to 60 to 70%. Also, this method does not use a pump, hence the survey equipment can be simplified and lightened thereby reducing the burden on investigators. Read more
NARO International Symposium 2018
NARO International Symposium 2018:Research and applications of water control and management in agricultural and rural areas was organized by Institute for Rural Engineering, NARO at Tsukuba International Congress Center on October 26, 2018. In this international symposium, prominent researchers from France, Netherlands, Taiwan and Japan gave presentation about the global trends, recent advancements and efforts for practical applications in water management research in rural engineering.
Development of an effective water distribution management control using ICT
The Institute for Rural Engineering, NARO (NIRE) has developed a water management control system that efficiently distributes water based on its usage by linking the pumping stations controlled by the land improvement district and the automatic hydrants in farms managed by farmers using ICT. The Irrigation and Drainage Automation System (iDAS) is expected to contribute in labor saving for facility managers in paddy field irrigation areas, saving in use of agricultural water, and saving in energy consumption of pumps.Read more
