'What remains to be said about cities when the planet is completely urbanized? This astonishing new Handbook seeks answers in the megacity-regions of the world, especially in the burgeoning urban constellations of eastern Asia. The book's diverse and topical chapters help planners and decision-makers, and ultimately inhabitants, to ''find their bearings'' in the unmoored vastness of a planet of megacities.'--Roger Keil, York University, Canada'The book fulfills a very timely mission: to reveal just how complex, varied, and multi-scaled the global urban reality has become - and is still becoming. The authors provide an antidote to simplifying notions about cities and megacities, updating our understanding of urban forces and dynamics, so that we might act upon them more effectively.'--Jeb Brugmann, Founder, ICLEI-Local Governments for Sustainability, Germany and author, Welcome to the Urban RevolutionThe Handbook of Megacities and Megacity-Regions provides a much needed assessment of 21st century urbanization, especially with its attention to the scale and density that characterizes todays cities. Its nuanced discussion of how to define megacities and megacity-regions is an important contribution to our understanding of one of the most critical megatrends of our times.'--Eugenie L. Birch, University of Pennsylvania, US
