The environmental aspect of cities is nowadays well recognized as a cri- cal element of urban development, management and regeneration. There are various environmental issues related to cities, and they have been a- lyzed in an individualized manner. Many types of technologies, such as wastewater treatment, have been developed to solve particular envir- mental problems. However, many of these problems are related to each other, and social and economic aspects are also important for urban reg- eration. A holistic view combining knowledge of various urban environmental f- tors such as water, heat, energy, air, materials and waste, and a practical approach based on such understandings are essential to manage contem- rary urban environmental issues, from a local scale to a global scale. The University of Tokyo has been conducting the 21st Century COE (C- ters of Excellence) Program on Sustainable Urban Regeneration. Transd- ciplinary courses have been offered for graduate students from the depa- ments of Urban Engineering, Civil Engineering and Architecture to present a holistic view of urban regeneration. This book is based on the contents of the transdisciplinary course on en- ronmental management and technology. I hope that its content will be u- ful for undergraduate and graduate students and for experts and policy makers in developed and developing countries.
