Department of Forest and Biomaterials Science

Reconizing that excessive and non-sustainable use of resources is the main drivers of global environmental problems, we must move away from a mere emphasis on economic productivity to a new set of social priorities that achieve sustainable and environmentally friendly use of natural resources. In other words, we must seek for a new way that enables harmonious coexistence of the earth and the humankind. Globally, forests cover 31% of the land, and they provide various ecosystem services including production of renewable resources. Hence, conservation and protection of forests, in combination with utilization of forest-based resources, are important for the survival of the human kind. More than ever, we need young people who can develop innovative strategies based on scientific understanding of forests and forest resources, in order to tackle global environmental issues. The Department of Forest and Biomaterials Science promotes research and education on forests and the various forest-based resources. Our unit conducts basic research on forests, including biological and biogeochemical research addressing biodiversity and ecosystem matter cycles. We also analyze chemical and physical properties of wood, cellulose and various organic substances. We also conduct applied research relevant for reduction of greenhouse gas emission. and for achieving a society with sustainable resource cycles. In addition to natural science approaches, we use sociological and economic approaches. Through collaboration of researchers across various fields of specialization, we aim for a transdisciplinary science on forests and biomaterials. In educational activities, we aim to nurture broad perspectives on forest science, as well as to build capacities for investigation through thesis research activities. The Department of Forest and Biomaterials Science has 17 laboratories, covering a wide range of research topics. They can be grouped roughly in three groups. The six laboratories in the first group, including “Forest Biology”, “Forest Ecology”, “Tropical Forest Resources and Environments”, “Forest Hydrology”, “Forest Utilization”, and “Biosphere Informatics”, conduct basic and applied research on forest ecosystem. The eight in the second group, including the laboratories of “Wood Processing”, “Biomaterials Design”, “Fibrous Biomaterials”, “Tree Cell Biology”, “Chemistry of Composite Materials”, “Chemistry of Biomaterials”, “Forest Biochemistry”, and “Energy Ecosystems”, conduct basic and applied studies on biomaterials. The three laboratories in the third group, including “Forest Resources and Society”, “Landscape Architecture”, and “Erosion Control”, study management of forests and landscapes, as well as disaster preventions in forested hills and mountains. In addition these core laboratories, the Field Science Education and Research Center and the Research Institute for Sustainable Humanosphere support our research and education missions through their field research center in Hokkaido and Ashiu, or through their large or advanced experimental facilities. During the first three years of our curriculum, undergraduate students will build foundational and comprehensive knowledge on forest and biomaterilas science through lectures and field and lab courses. The 4th year students belong to one of the 17 laboratories to conduct thesis resaerch. Our goal is to help students obtain specialized knowledge on forests and biomaterials, and build capacity to contribute to research and innovation with high moral standards.
