The Department of Biological and Environmental Engineering (BEE) deals with the creation and preparation of good environments in rural areas and the production control of living things. Technologies in this field are essential for human beings and other life resources to continue to coexist on earth.

This department has four branches of: Rural Environmental Engineering (REE), Biological Systems Engineering (BSE), Biological and Environmental Information Engineering (BEIF), and Ecological Safety Studies (ESS) which was newly established in 2006.

REE seeks to achieve advances in modern technologies associated with the engineering of land foundations, water resources, soil conditions, plants and air resources. It aims to encourage the efficient production of food and to conserve the environment of the earth, especially in rural areas, by harmonizing production with natural ecological systems.

BSE aims to develop advanced techniques and research on bio-engineering, biological process control, biosensing and robotics, bioenergy production, and bio-farming in outer space, by making greater use of life functions themselves.

BEIF applies the latest information technology to strive for the harmonious coexistence of life and the environment, and optimized food production. Information on the effects of changes in condition of both the geosphere and food materials is dealt with.

ESS is an associated branch of the Department of BEE in the National Institute for Agro-Environmental Sciences (NIAES) which is located in the science city of Tsukuba. NIAES is the leading institute on environmental sciences in agriculture. ESS conducts interdisciplinary studies on atmosphere and soil environments, the material cycle in agro-ecosystems, and ecological statistics as the basis for such studies.
