Rebirth of the Environment in Germany: An Attempt to Transform into a “Lean City”

Abstract

Today, it is no longer possible to build cities based on the urban model of a continuously expanding city. Cities must be planned in a way that promotes a further medium-term decrease in population figures; moreover, the structures of cities can be generated differently. The IBA ”Urban Redevelopment” 2010 in Germany is an experiment conducted in order to display new development patterns for cities in Japan. The transformation ”from a shrinking city to a lean city” suggests to us a method to achieve the rebirth of the urban environment.
