Hongo Lab
Machine-translated · View original
A lab that diagnoses crop yields and the condition of farmland from satellite images.

AboutAbout the lab
Watching Asia's farmland from space.
The Hongo Lab studies agricultural remote sensing, using satellite images to examine the condition of farmland and crops.
Just as a doctor diagnoses a person's health from medical checkup images, the lab uses satellite images to examine crop yield, nutritional status, soil type, and the occurrence of pests and diseases.
The lab matches yield and quality data measured in the field with satellite images to build estimation equations, making it possible to estimate yield and quality without visiting the site.
The lab also places importance on educating people involved in food production. With research and education as twin pillars, it works with partners in Japan and abroad.
Key terms
- Remote Sensing
- A technology that measures conditions on the Earth's surface from a distance, without touching the target, using satellites and other platforms
- GIS
- A system that overlays location information and various kinds of data on a map to manage and analyze them (Geographic Information System)
- Agricultural Insurance
- An insurance system that compensates farmers for losses when harvests decline due to natural disasters and other causes, helping them to keep farming
ResearchResearch themes
Aiming for the continued improvement and development of food production systems that are mindful of environmental conservation, the lab conducts research and practice using environmental diagnostic information such as satellite images, GIS, weather data, and ground measurements. With research and education as twin pillars, it works with partners in Japan and abroad.
*Illustrative imageWatching Asia's Farmland from Space
From satellite images of green rice and golden wheat, the lab reads that year's harvest and the damage from drought. It uses remote sensing data to diagnose the foundations of food production, and conducts research on putting methods based on spatial information into practical use in society.
*Illustrative imageUse in Damage Assessment for Agricultural Insurance
The lab uses spatial information to assess paddy rice yield and the percentage of yield loss. It is developing new assessment methods that make damage assessment under agricultural insurance schemes more efficient and lower its cost. Implementation in society is moving forward in Japan and Indonesia.
