This course presents a range of urban and regional theories which help to conceptualize the activities of people and societies in space, in the physical domain of cities and regions. They serve to enhance understanding of the growth and the development of human communities and assist in the prediction of future trends in the built and the natural environment. Concepts of sustainability and long term viability are featured. The theories are drawn broadly from the disciplines of architecture, urban planning, geography, landscape architecture, sociology, economics and political science. They are presented so as to be useful in application and action in the spatial realm. They address a range of scales from the neighborhood and community, through urban, metropolitan, national/sub-national, and global, environmental/economic regions.
