Degree Program in Agricultural Sciences

Division of Biosphere Resource Science and Technology

The Division of Biosphere Resource Science and Technology consists of a total number of 20 disciplines (or research fields), including collaborative research fields participating from national research institutes. This division covers following two major fields, Biological Resource Science and Biosphere Environment Science.

Biological Resource Science field focuses on Plant genetics and breeding, Crop science, Olericulture and floriculture, Pomology and postharvest physiology of fruits, Animal science, Crop production system, Plant molecular biology, Metabolic network biology, Disease vector control, Epigenetics, Plant stress biology and International food production and development sciences. The educational goals of the field are to become knowledgeable and acquire research skills of the respective fields on molecular biology, genetics, physiology, and ecology in plants, animals, and insects for practical use, sustainable agriculture production, and environmental conservation in natural ecosystems and agro-ecosystems.

Biosphere Environment Science field focuses on Plant parasitic mycology, Applied entomology and zoology, Environmental soil chemistry, Environmental plant biochemistry, Forest ecotopology, Conservation of regional resources, Climate change impact assessment on vegetation and Forest genetics and ecology for sustainable tropical forest management. The educational goals of the field are to become knowledgeable and acquire research skills of comprehensive analysis of biosphere factors, and development of sustainable control and management systems for those factors.
