Arcology is Paolo Soleri's concept of cities which embody the fusion of
architecture with ecology. The arcology concept proposes a highly
integrated and compact three-dimensional urban form that is the opposite
of urban sprawl with its inherently wasteful consumption of land,
energy, time and human resources. An arcology would need about two
percent as much land as a typical city of similar population. Arcology
eliminates the automobile from inside the city and reserves it for use
outside the city. Walking would be the main form of transportation
inside an arcology. The miniaturization of the city enables radical
conservation of land, energy and resources. Arcology would rely as much
as possible on the sun, the wind and other renewable energy so as to
reduce pollution and dependence on fossil fuels. Arcology needs less
energy per capita thus making recycling and the use of solar energy more
feasible than in present cities.
