This book provides a multi-scale reading of the spatial “elements” in which the extensive urbanity in Yangtze River Delta is constructed, and from there an imagination of a new paradigm of urbanization. The urbanization in Yangtze River Delta today is in need of a new interpretation and paradigm. The delta is a territory with city cores but it also has vast dispersed urbanization where the agricultural and non-agricultural activities and spaces are mixed and interlinked, a desakota (McGee, 1991). This book attempts to answer a basic question: what is the desakota in the Yangtze River Delta made of? The research Horizontal Metropolis led by Prof. Paola Viganò at EPFL, Switzerland focuses on the form of the contemporary city – the fragmentary spatial condition and dispersed urbanity all over the world. The study on Yangtze River delta is part of its research frame.
