Education and research in the environmental science and infrastructure engineering course aims to make creative contributions to a new environmental and societal infrastructure. For this purpose it aims to clarify the mechanisms underlying the manifold environmental issues arising in various spheres in which humans exist together with other living organism, and, ultimately, to resolve them. It tries to build a suite of techniques, which improve sustainability and allow human society to coexist with the natural ecosystem. The field of environmental science covers circulation, measurement and control of environmental chemicals, and ecology; the field of environmental planning covers regional planning and design, and coastal and river engineering; the field of human environmental infrastructure engineering deals with material and construction systems, seismological engineering and environmental and geotechnical engineering. This course is taught not only by faculty at Saitama University, but also profits from the cooperation of visiting lecturers and researchers from the Center for Environmental Science in Saitama (CESS) and the Geosphere Research Institute (GRIS) at Saitama University. The goal of education in the course is to mold researchers, who are able to use the most advanced scientific and engineering methods and tackle problems from an international point of view in a comprehensive and systematic way, and eventually solve them, thus improving the sustainability of society and the biosphere through environmental preservation and making a contribution to the infrastructure that human society is built on.
