Covering 30% of the earth's surface, forests are a massive collection of biological life that accounts for 90% of all life on land. This is why forests both play a large role in sustaining the global environment and are important as a renewable resource. In addition, not only do they function to adjust the environment through land conservation, water resource cultivation, and climate mitigation, forests contribute a great deal to our lifestyles by, for example, providing us with green spaces to gain mental relaxation. In this course, we seek to understand the features of forests, with their multifaceted functions, and find methods for using these resources and diverse functions sustainably while maintaining harmony with the natural environment. We do this through lectures, seminars, and practical training in the university's forest. Topics covered include ecology, botany, microbiology, soil science, chemistry, physics, and information science.
