Why Cities are inherently unsustainable

… and why they are a key to sustainabbility. Presentation by William Rees in March 2003. Bille Rees argues that “For all the recent advances in technology and resource productivity,’great cities’ remain ever more materially dependent on a vast (and increasingly global) hinterland. They can produce the’wealth of nations’ only by first consuming the products and services of the ecosphere.” The average ecological footprints of residents of high-income countries range between four and ten hectares. Therefore the ecological footprints of high income cities are typically hundreds of times larger than their political or geographic areas. The key is exploiting the urban sustainability multiplier.
