The urban environment where we live is defined as a community of human beings as well as a physical complex made of buildings and civil constructions. At the same time, urban society may not be maintained without any dependency on the natural environment. Environmental problems and creation of the urban environment should be understood in the context of such interrelationships among different components as above described. Department of Socio-Cultural Environmental Studies applies the trans-disciplinary approaches within a department which is a key concept of the whole Graduate School of Frontier Sciences.
