Ecological Environmental Physics Lab
Machine-translated · View original
A lab that protects ecosystems by using sensors to measure the weather and wildlife of farmland and wetlands.
AboutAbout the lab
Measuring and protecting the environment of farmland and wetlands.
The Ecological Environmental Physics Lab studies the weather and ecological environments of farmland, forests, rivers, lakes, and wetlands through field observation.
The lab works on evaluating the environmental functions of terrestrial ecosystems, crop responses to climate change, and phenomena related to agricultural meteorology.
Lecturer Yamada's team uses robotic technologies such as cameras, sensors, and UAVs to develop systems that automatically monitor animal populations from a distance.
Key terms
- UAV
- An aircraft that flies without a person on board, either by remote control or automatically. Also called a drone.
- GIS
- A system that overlays location information and data on a map for analysis and display.
- Adaptive management
- A way of managing nature in which measures are tried and the approach is revised while observing the results.

ResearchResearch themes
The lab observes the weather and ecological environments at various scales in farmland, forests, rivers, lakes, and wetlands, aiming to contribute to ecosystem conservation, environmental planning, and stable agricultural production. The themes below are those pursued by Lecturer Yamada's team within the lab.
*Illustrative imageSystems That Automatically Monitor Wildlife
The lab combines sensors such as cameras, sonar, and water quality meters with IoT, UAV, image processing, and AI technologies to develop systems that automatically monitor animal populations in remote places.
*Illustrative imageConserving and Restoring Nature
Data collected through wide-area observation are analyzed with GIS and statistical models to identify when, where, and why the environment has deteriorated. The lab proposes measures to remove the causes, and when a fundamental solution is difficult, it explores ecosystem recovery through adaptive management, in which approaches are tried and then revised.
*Illustrative imageSmart Countermeasures Against Wildlife Damage
The lab develops devices that use sensors and AI to automatically detect wild animals and drive them away without harming them. Recent work includes a laser deterrent device for crows and a deterrent device for greater white-fronted geese.
*Illustrative imageWetland Conservation Activities
The lab carries out conservation activities on the Hokkaido University campus and in wetlands and lakes in Hokkaido. It also holds seminars on wetland research and conservation activities.
