Farmland and Environmental Engineering Lab
Machine-translated · View original
The lab tackles farmland and environmental problems through the science of soil and water.

AboutAbout the lab
People cannot live apart from the soil.
The Farmland and Environmental Engineering Lab studies farmland and environmental problems based on the science of soil and water.
Farmland around the world faces a range of environmental problems, including salt accumulation in arid regions, groundwater contamination from fertilizer runoff, and overuse of water resources.
In Japan too, the foundations that support agriculture are at a major turning point, due to a shortage of farmers, the introduction of crops to replace rice, and advances in information and communication technology.
The lab addresses these issues with methods suited to each subject, including field measurements, GIS, experiments with physical models, and computer simulations.
Key terms
- Converted paddy field
- Farmland where a paddy field has been switched to an upland field and is used to grow upland crops such as soybeans and wheat
- Waterlogging damage
- Damage in which too much water accumulates in the soil, leaving plant roots short of oxygen and stunting crop growth
- GIS
- Geographic information system. A system that overlays various kinds of information, such as land and water data, on a map for analysis

Based on the science of soil and water, the lab studies water and soil management on farmland, from paddy fields in Japan to arid regions overseas. It combines field measurement and monitoring, GIS, model experiments, and simulations.
*Illustrative imageDrainage and Waterlogging Damage in Converted Paddy Fields
On farmland where paddy fields have been converted to upland fields, the lab investigates how subsurface drainage works. It develops low-cost techniques for evaluating drainage performance, as well as drainage technologies that assess and prevent waterlogging damage to crops.
*Illustrative imageSmart Agriculture and Water Management in Paddy Fields
The lab develops methods that use remote and automated water management to control the water, heat, and nitrogen conditions in paddy fields, and examines how changes in these conditions affect rice yield and quality. It also works on technologies to reduce damage caused by high temperatures.

In oasis communities in Egypt's Western Desert, the lab is building models for the sustainable use of water and land resources.
