This volume addresses the complex relations between urban artifacts and urban life. The contributions show how architects, planners, and urban designers describe and give shape to the city, while novelists, humanists, and other scholars examine its operations and performances. The essential question is: How does the physical character of an urban environment influence or enable the events that take place within a specific setting? Contributors from a wide range of fields address the role and life of cities as diverse as Baku, Buenos Aires, Cairo, Detroit, Jakarta, Johannesburg, Mumbai, Paris, Quito, St. Petersburg, Tel Aviv, Tirana, and Toronto. Portfolios of contemporary photography present the layered realities of urban life today. With contributions by Arjun Appadurai, Eve Blau, Svetlana Boym, Lindsay Bremner, Jana Cephas, Felipe Correa, Rahul Mehrotra, Mohsen Mostafavi, Antoine Picon, Gyan Prakash, Nasser Rabbat, Rafi Segal, Jorge Silvetti, AbdouMaliq Simone, and Charles Waldheim. Mohsen Mostafavi , an architect and educator, is dean of the Harvard University Graduate School of Design and the Alexander and Victoria Wiley Professor of Design. He is the editor of Ecological Urbanism (with Gareth Doherty).
