The lab uses maps, AI, and drones to evaluate energy and the benefits that nature provides.
AboutAbout the lab
Evaluating energy and the environment for a society that lives in harmony with nature.
The Hayashi Lab evaluates impacts on energy and the environment, and conducts research to build a sustainable society.
It focuses in particular on spatial evaluation of land use and the natural environment, and works to resolve issues related to renewable energy, ecosystem services, and the economy and society in an integrated way.
The lab evaluates impacts at many scales, from small-scale field surveys to the global scale across countries.
It takes an interdisciplinary approach that combines spatial analysis with GIS (geographic information systems), AI, drones, and field surveys.
Key terms
- Ecosystem services
- The many benefits that nature provides to people, such as forests storing water and supplying timber and food
- GIS
- A system that overlays maps with data tied to locations and analyzes them by computer
- Renewable energy
- Natural energy that is not used up when it is used, such as solar, hydro, and biomass
ResearchResearch themes
The lab conducts research to evaluate impacts on energy and the environment and to build a sustainable society that lives in harmony with nature. It combines satellite data, GIS, drones, field surveys, and AI to carry out evaluations from the local to the global scale.
*Illustrative imageEnergy and Environmental Evaluation with Satellites and GIS
Using satellite data and GIS data, the lab spatially evaluates energy, the environment, and ecosystem services at the scale of cities and prefectures. Alongside analyses of Nagoya City, Toyota City, and other areas in Aichi Prefecture and the Tokai region, it is developing evaluation methods that can be used in developing countries such as Myanmar and Laos.
*Illustrative imageForest Field Surveys and Drone-Based Evaluation
Through forest field surveys, the lab has comprehensively collected information on forest ecosystem services. It studies methods for creating detailed 3D images from forest images and videos taken by drone in different seasons, and for estimating biomass and carbon stock from them.
*Illustrative imageIntegrated Evaluation Models Using AI
The lab uses k.LAB, an integrated assessment platform that uses AI ontologies and semantics and was developed at the Basque Centre for Climate Change (BC3) in Spain. With it, the lab is working toward building a Japanese model for energy and environmental evaluation.
