Global Cities is a big multi-media exhibition at London's Tate Modern museum. Starting with the premise that "more than 50% of us now live in cities, and, according to the United Nations, this number is set to rise to 75% by 2050.", it examines Cairo, Istanbul, Johannesburg, London, Los Angeles, Mexico City, Mumbai, Sao Paulo, Shanghai and Tokyo. Drawing on comparative data, the exhibition explores these huge sprawling cities using 5 themes: size, speed, form, density and diversity.
The visuals are huge and dynamic, there are videos, old film footage and photographs by artists who come from or have a relationship with the cities. In addition, special projects have been commissioned, using London as their base. Size examines some of the most populous cities--Tokyo, Mexico City and Sao Paulo are expanding their urbanised regions dramatically. Speed looks at the speed of urban change, brought on by immigration and speculative commercial development and how these factors are being managed in Shanghai, Istanbul, London, Cairo and L.A. Form provides an overview of the different urban forms of five cities: Istanbul, Johannesburg, London, Mumbai and Tokyo. Satellite photographs show the diversity and complexity of the cities and the challenges urban planners face. Density compares the number of people living within the boundaries of four cities: Cairo, Mumbai, London and Mexico City. And finally, diversity can affect a city by fostering integration or segregation. Cities that are integrated are designed around shared facilities such as parks and good public transport. Much to think about in a visually stunning and assaulting exhibit. :: Tate Modern
