Faculty of AGRICULTURE
Life, Food, and Environment
Five departments offer opportunities to acquire academic and advanced knowledge and develop broadened perspectives.
Human society coexists with various organisms, such as animals, plants, and microorganisms, on the Earth for our survival. To use these bioresources more sustainably, it is essential to acquire a deep understanding about the mechanisms, by which organisms maintain their life and the ways, in which ecosystems are constructed. Additionally, analysis through technological expertise and social science methodologies is also needed to ensure human activities support vital ecosystems. Students are required to obtain fundamental knowledge offered by the individual department, in which they major and to make active efforts to broaden their vision by extending their interest into related fields.
In next academic year, 5 of 6 Departments, namely the Department of Bioresource Science (Agricultural Biology), Department of Applied Life Sciences (Agricultural Chemistry), Department of Agricultural and Environmental Engineering, Department of Food and Environmental Economics and Department of Forest and Biomaterials Science offer opportunities to study in Faculty of Agriculture.
Year 1 / Introductory learning
In the Faculty of Agriculture, students are enrolled in the individual department upon admission and follow a four-year education program specified by their departments. In addition to knowledge about natural sciences, such as biology, chemistry, and physics, methodologies used in social sciences must also be learned to study the agricultural sciences. The departments have established integrated curricula (lecture programs) that incorporate liberal arts subjects together with specialized subjects. It is important for first-year students not to limit their study within the disciplines selected in their departments in order to expand their base of knowledge. Therefore, first-year students should primarily concentrate on general education subjects, including subjects in natural sciences, humanities/social sciences, and foreign languages. They can also participate in health and physical education courses or add other subjects, including courses in international education, which provide opportunities for social exchanges with international students.
Years 2 and 3 / Enhanced learning
Second-year students take the basic courses in their specialized subjects in the second semester of Year 2 (autumn and winter) and prepare for a more intense specialized education in Year 3. In addition to lectures, the Faculty preferentially offers students opportunities to participate in specialized courses offering experiments, practical exercises, and seminars. In this way, students receive high-quality training in experimental techniques and methods, in preparation for specialized study later in their respective departments. The Faculty is one of the most enthusiastic at Kyoto University in terms of encouraging international exchange activities, sending many undergraduates to international institutions.
In the third year, students only take specialized subjects. Year 3 is an important year as the students take their first significant steps toward becoming researchers. The third year is when students must determine their study fields (laboratories). Third-year students are required to investigate their future career options by visiting laboratories and attending lectures with regularity. The departments have well-designed mechanisms to help assign third-year students to their laboratories.
Year 4 / Finalized learning
In Year 4, students work on research projects and assignments in their research fields throughout the year and prepare graduation theses. This is the first step they take as researchers by working on contemporary topics with graduate students under the supervision and mentorship of academic staff. Therefore, fourth-year students are devoted to their own research, as well as assigned work in their study field seminars. Students intent on pursuing advanced studies also need to prepare for the Graduate School entrance examination. The students who earn the required credits are awarded a bachelor's degree (in agriculture).
Study programs in the five departments
Department of Bioresource Science (Agricultural Biology)
Humans have harnessed a vast diversity of plants, animals, and microorganisms that inhabit and flourish on the land or in the ocean--not just to sustain our livelihoods and activities, but also to support and enrich our daily lives. For centuries, humans have applied a great deal of effort and wisdom to find ways to grow and raise bioresources so as to maximize their potential and to develop environments suited for their habitation and growth, while at the same time improving such precious resources to better serve our purposes at any given time. These efforts have paid off to an extent, and an abundance of food and other necessities are within easy reach in some countries. On a global scale, however, humans are faced with the harsh reality that food production is not likely to keep pace with the population explosion of this century, and the excessive use of bioresources is severely damaging the global environment and destroying ecosystems. As this is the case, the citizens of earth are required to confront the momentous challenge of ensuring the stable production of bioresources and constantly increasing their productivity and quality. At the same time, we must achieve harmony with the environment and reduce negative impacts on ecosystems.
The Department of Bioresource Science offers a broad range of educational opportunities, from foundational knowledge to applied technology, in order to develop individuals who are ready to tackle this immense challenge. The Department covers as many as thirty specialized fields (see below for details) to study a diverse range of organisms, including food crops and other plant resources, livestock and other animal resources, and seafood and microorganisms in the ocean, from multifaceted perspectives on macro and micro levels, i.e., from populations and individuals to cells and molecules. Relatedly, efforts are being made to carry out various research projects, in a bid to protect each bioresource from invasive enemies, maintain preferred growth/habitation environments, and ensure high productivity in adverse environments. Some of those projects even attempt to create new species.
The broad-ranging academic fields covered by this Department can be grouped into four, as shown below. It is thus recommended that students take courses from each course in their first two years to study bioresource science as a whole, focus mainly on subjects from courses in which they have become interested in their third year, and proceed to select a field with which they are affiliated in their fourth year.

Department of Applied Life Sciences (Agricultural Chemistry)
The 21st century is said to be the era of "bioindustry," and it is thought to be a time of progress for the environment, food, energy, health, and welfare. At the core of this fast-growing sector is biotechnology, a means of utilizing biological functions in advanced applications.
At the Department of Applied Life Sciences, students learn basic and advanced knowledge across a broad range of academic disciplines, giving them the ability to follow the principles of life phenomena. This in turn allows them to analyze various issues that may arise on the frontlines of agricultural production, the fermentation, food processing, and chemical industries, and environmental conservation, and then to apply their research findings to the burgeoning realm of biotechnology.
Our Department encompasses the 13 fields of education and research below, which cover a wide range of organisms--from humans to microbes. The underlying academic purpose here is to elucidate life phenomena on the molecular level. Targeting inorganic compounds, low-molecular organic compounds, and other biomolecules such as nucleic acids, proteins, lipids, and polysaccharides, we set for ourselves the task of bringing to light biofunctions that may be caused by properties of individual molecules as well as interactions among molecules. Another fundamental research topic is the elucidation of how biomolecules work in relation to their cell structures.
To serve these purposes, we offer a four-year integrated curriculum. In the first two years, students take common basic subjects of physical chemistry, organic chemistry, and biochemistry, as well as introductory subjects that cover the entire range of academic disciplines that our Department has to offer, so that they can set their own learning goals. In the last two years, students systematically learn a broad range of disciplines--from basic to applied research--that concern animals, plants, and microorganisms, while performing lab work and practical training carefully prepared for them to understand related theories empirically. In the fourth year, students are assigned to laboratories, where they learn about approaches and attitudes toward creative research as they work on new challenges as budding researchers.
Through this curriculum, we develop self-driven biotechnology researchers and engineers who can respond to societal demands. Successful students must be motivated with a sharp and clear vision and be fully prepared to challenge themselves to attain their educational objectives.
Through its research and education, the Department of Applied Life Sciences aims to develop students who:
- Study organisms and life phenomena deeply at the cellular and molecular levels and understand them in a chemical context;
- Understand the commonality and diversity of biofunctions of microorganisms, plants, and animals;
- Spearhead new discoveries and inventions to applied research; and
- Gain skill with research approaches and logical thinking through the aforementioned research experience and make the most of applied education through lectures by guest speakers from private enterprises and visits to plants.

Department of Agricultural and Environmental Engineering
Food security is the most vital necessity for the survival of humanity. In this respect, agriculture is one of the most sublime and fundamental human activities, playing an integral part in the process of food production. It is believed that agriculture (cultivating plants and livestock) dates back roughly 10,000 years. The "discovery" of agriculture (i.e., a new method of procuring food whose carrying capacity was much higher than that of conventional ways of hunting and gathering) led humankind on to a path of rapid evolution. From that point onward, humans have utilized wisdom and innovation to advance and sustain the art of agriculture while meeting the needs of our times. At the same time, progress in engineering and technology that form the foundations of agricultural production has been instrumental in enhancing the productivity of land and agriculture workers. This is evidenced by the fact that the Faculty of Agriculture, Kyoto University had an engineering department (the Department of Agriculture and Forestry Engineering, later reorganized into an engineering department, the Department of Agriculture Engineering, to specialize in agriculture studies) since its inception in 1923 to conduct pioneering education and research on engineering/technical strategies and methodologies that maximize agricultural productivity. Towards the end of the last century, the emergence of global issues that could threaten the survival of humankind promoted a paradigm shift, and it also became necessary in the engineering field to redesign our basic research approaches to and perspective on the world under the more comprehensive and contemporary framework of "the environment." Based on this background, the Department of Agricultural and Environmental Engineering came to be in 2001.
This Department is devoted to research and education on the use of engineering and technology in "agricultural and farming regions;" namely, rural regions in which people engage in agricultural production activities for a living. Recent years have seen a growing recognition that rural regions have much more distinguishing precious features, compared to urban regions. This renewed recognition is chiefly attributable to the multifunctionality of agriculture, which serves the preservation of national land, the natural environment and ecosystems, on top of its inherent function of food production. Now, for rural regions to develop in a sustainable manner, it is necessary to properly develop and preserve water and soil (land), two key elements of environmental infrastructure in such regions, the production environment, such as production control systems and systems for harvesting, processing, and storing farm products, and the living environment in the regions. At the same time, harmony with the natural environment must be achieved. It is also important to utilize wisely potential resources unique to the rural regions, such as the development of biomass energy. The concept of "achieving harmony with the natural environment" means to stop to think how humankind should produce food and develop energy, both of which are necessary for human survival, while working in harmony with biosystems, ecosystems, and landscapes by respecting their inherent right. "All regions are cells of planet Earth," and maintaining a sound regional environment is vital for the conservation of the global environment. To make this ideal state of rural regions a reality, it is crucial to pursue engineering and technology studies in the realm of applied science based on the solid foundations of interdisciplinary fundamental sciences, with fields ranging from natural science to social science. Studies of agricultural and environmental engineering take scientific approaches to rural regions within such a paradigm. As a body of engineering and technological knowledge, these systematic studies are expected to play a significant role in solving the problems that threaten the survival of humankind, including those concerning agriculture and farming villages, the environment, and food and energy.
Education at the Department of Agricultural and Environmental Engineering is given mainly in seven research fields, which are divided into four fields of the "Rural Environmental Engineering" and three of the "Bioproduction Engineering." The first- and second-year students gain a basic overview of agricultural and environmental engineering, while third-year students mainly take subjects from a family to which the field that they plan to be affiliated with in their fourth year belongs.
In the fields of the "Rural Environmental Engineering" which consists of 4 fields (Agricultural Facilities Engineering, Water Resources Engineering, Hydrological Environment Engineering, and Rural Planning), students learn about theories for creating rich and beautiful regional environments that encompass production, living, and natural spaces. They also go on to learn how to improve and conserve such regional environments with engineering techniques that work on water, soil, and the environment, as well as study the technological approaches needed to achieve this. Students also learn how to utilize water and land in a regional setting with the conservation of national land and the environment in mind, along with how to plan, design, construct, and maintain various structures that give a concrete shape to their learning outcomes.
In the fields of the "Bioproduction Engineering" which consists of 3 fields (Agricultural Systems Engineering, Field Robotics, and Bio-Sensing Engineering), students learn how they should go about controlling production, harvesting, processing, and storing food, and developing biomass energy. They do so while considering not only the local natural environment but also the global environment, resource circulation, labor-saving, and energy-saving, as well as learning their underlying principles. Students are also expected to learn the skills and methodologies needed to realize all of the above. To this end, students study relevant bioresources, information processing, systems design, measurement and sensing technologies for organisms, machine design, mechatronics, physical properties of farm products and their non-destructive quality evaluation, and processing technology.

Department of Food and Environmental Economics
Of the challenges that humankind faces today, those concerning food and environment are particularly relevant to everyday life. Although they are faced differently depending on the context, food issues and environmental problems arise in both developed and developing countries, regardless of political and economic system. Indeed, they are increasingly understood as the consequence of economic policies fixated on growth and rapid development. With growing awareness of our declining natural resources, more emphasis has been placed on the possibilities for sustainable development. To bring about such an alternative development path, governments around the world need to not only adjust their domestic policy, but also to coordinate with their counterparts at the global level to ensure that progress can be achieved collaboratively at the international scale. Unlike manufacturing industries, which rely on inorganic resources and global commodities, agriculture, forestry, and fisheries have a uniquely local character that is rooted in natural ecosystems and communities. Here, sustainable development means achieving harmony between economic output, environmental conservation, and local culture. We strongly believe that since food and environmental problems are the byproducts of human institutions and economic systems that humans can also solve these problems.
The Department of Food and Environmental Economics aims to find solutions to these problems using a diverse social science approach, while at the same time absorbing relevant knowledge and experience from the natural science approach of the departments in the Faculty of Agriculture. This organization allows us to determine how research findings can be applied and accepted in the real world, with the ultimate goal of encouraging more progressive and interdisciplinary scientific approaches in the agricultural sciences.
To this end, we deliberately look at agricultural production in a broader cultural and economic context. While other departments in the Faculty of Agriculture adopt predominantly natural science methods, this Department alone advocates a social science approach, rooted in the belief that this can better clarify the nexus of human and natural activities that comprise agriculture. In more concrete terms, we study the characteristics of people working in agriculture, forestry, fisheries, and livestock businesses as well as the social and economic contexts, such as the farm, mountain, and fishing villages they work in, with an eye toward developing rural industries sustainably and equalizing conditions with urban areas. To balance conservation of local environment and culture at both regional and global levels with the need to encourage economic advancement, we draw insight from international studies of agriculture, rural and urban community development studies, and environmental management as well as relevant industries.
The Department of Food and Environmental Economics is divided into eight fields of education and research, which can be roughly clustered into three groups, as outlined below.
The first group covers two fields, in which students take micro-level approaches to studying problems involving agriculture and farm families. In these fields, students learn agricultural business management and accounting information processing to understand agricultural problems from the perspectives of individual farming families and agricultural organizations. As such, this group relies primarily on field survey methodology. The second group comprises four fields that provide students with a micro- and macroscopic approach to resource and environmental problems on a regional level using rigorous empirical analysis. In these fields, students have opportunities to encounter current food and environmental problems from regional and national perspectives and then learn basic theories about conservation and development of regional environmental resources, policies for agriculture and forestry, and the development of farming communities in developing countries. The third group includes two fields in which students consider issues of food, agriculture and farming communities on the basis of history and philosophy, learn basic techniques to discover how such issues have evolved, and conduct cross-national comparisons. In these fields, students are given opportunities to examine the industrial and post-industrial aspects of agriculture, forestry, and fisheries and food system development, as well as the impact that historical trends have had in shaping farming communities, rural-urban relationships and, more generally, agriculture as a field of science.

Department of Forest and Biomaterials Science
Recognizing 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 biomaterials science through lectures and field and lab courses. The 4th year students belong to one of the 17 laboratories to conduct thesis research. 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.
