Harvard Design School's Project on the City is a graduate thesis program that examines the effects of modernization on the urban condition. Each year the Project on the City studies a specific region or phenomena, & develops a conceptual framework & vocabulary for urban environments that can not be described within the traditional categories of architecture, landscape, or urbanism. In order to understand new forms of urbanization, thesis advisor Rem Koolhaas & students from the fields of architecture, landscape, & urbanism, document & analyze areas of study through a combination of field research, statistical analysis, historical developments, & anecdotal situations. The result of each project is an intensive, specialized study of the effects of modernization on the contemporary city. During the 1996-1997 period, Harvard's graduate students studied China's Pearl River Delta (PRD), a cluster of five cities with a population of twelve million destined to reach thirty-six million by the year 2020. The establishment in the PRD of Special Economic Zones--"laboratories for the contained unleashing of capitalism"--hastened an unprecedented experiment in urbanization on an astonishingly large scale. Great Leap Forward contains essays which explore, in a theoretical & statistical context, the results of this rapid modernization that has produced an entirely new urban substance.
