Sustainable Resource System Sciences

As the world's population continues to increase, humanity will be required to use the planet's limited resources sustainably. Maintaining the sustainability of food production in particular will not be limited to supplying us with fresh, tasty food; it will play a major role in the conservation of the global environment and the reuse of bioresources. In addition, forests contain roughly 90% of terrestrial bioresources, so we need sustainable use of bioresources such as wood and molecular materials produced from forests, as well as the conservation of the biodiversity and habitat of the life within them. In this course, we shall examine sustainable resource system sciences, which have developed from a basis in agrobiology and forest resources and environmental science, from a range of new perspectives. We shall seek out ways to solve global food issues, sustainably use bioresources that include the multifaceted functions of forests, and to help sustain forest ecologies that are formed through a rich, diverse range of life.

Atmosphere and Sustainable Earth System Science

Changes in the earth's environment such as climate changes and abnormal weather work in concert with ecological environmental systems and earth systems that are made up of the atmosphere, the oceans, the soils, plants, the hydrosphere, the ecosphere, and the activities of humans and other animals. We conduct research on the basic structures, change processes, symbiotic relationships, and interactions that make up these systems, such as weather, the water cycle, the ocean cycle, evolution of the earth, climate and terroir, topography, conservation of the global environment, the physiological ecology and ecological harmonization of flora and fauna, and human activities, all with reference to observation, measurement, experimentation, investigation, remote sensing, and numerical analysis. We provide education and research to train people who can use the new scientific knowledge gained from this research and the thinking and practical skills learned through research to give them perspective on the future of the earth and the human race, allowing them to contribute to the creation of the next-generation culture and construct a sustainable society, and be active around the world, tackling them on a global stage.

Applied Biological Chemistry

In this course, we clarify the physiological functions and structures of molecules produced by terrestrial and marine life, including animals, plants, algae, microorganisms, and a wide range of other bioresources using the strategy of bioscience and biotechnology in order to effectively utilize their nutritional component or bioactive substances. Using these results, we aim to establish a new basic and applicable technological system for the development of new functional molecules or foods, or environmental technology. Furthermore, we carry out advanced research and education from the perspectives of chemistry, biochemistry, molecular biology, and bioengineering, with a focus on research into the gene expression mechanisms of animals and microorganisms, the physiological functions of plant and animal cells, bio-information sensing and processing technologies, improvements of food functionality, and the maintenance of health and quality of life, as well as the development of technologies for using unutilized bioresources.

International Sustainable Resource Science

We carry out research and education to use unique local assets appropriately in rural villages around Japan and the world, with the aim of creating sustainable socio-economic development. Specifically, we emphasize fieldwork, providing education and research on socio-economic fields with the aim of constructing a social system to achieve sustainable use of local resources. We also carry out education and research related to practical utilization technology for regional resources targeted at developing nations in particular, on a foundation of biology.

Environmental and Agricultural Engineering

In this course, aiming for the creation and conservation of a rich environment, we use advanced scientific and engineering methods to solve issues regarding the environment and agricultural and fishery industries, with the goal of contributing to regional development with a global perspective. Environment information science uses the measurement, control, and systems engineering of environmental information, with information processing technology at its core, and building on a foundation of knowledge related to bioecology. Regional Conservation Engineering is designed to create a rich, safe, secure regional environment for rural regions. Ecosystem Recycling Systems Engineering covers the material recycling system and food system of the ecosystems, including the natural environment and human society, as well as environmental conservation technology. In addition, we provide research and education to develop people who can contribute to the growth of sustainable societies that are rooted in the region.

Marine Biological Science

In this course, our research field is the hydrosphere, with a focus on the oceans but also including lakes and rivers and other fresh water areas. We also look at everything in them, from plankton to algae, crustaceans, shellfish, fish, and marine mammals. We aim to understand the workings of these diverse life forms at the genetic, cellular, individual, community, and ecosystem levels. The methods we use include genetic analysis, physiological ecological analysis, collective analysis, behavioral analysis, and using marine observation technologies. Moreover, we also carry out research and education on the conservation of marine and freshwater ecosystems and biodiversity, and on methods to sustainably reproduce and effectively utilize marine bioresources such as fish, shellfish, algae and so on. We also aim to enrich human life by the stable use of bioresources through the appropriate management of them as a resource, and effective increase and farming methods for them.
