Contemporary Modifications to the Land Rent Theory
In most contemporary cities, notably in North America, the land rent
theory is still valid, but requires a set of modifications:
- The downtown area is not necessarily to most accessible location.
The rapid extension of metropolitan areas involves new locations
far from the CBD, notably in suburbia (E). This has favored the
emergence of sub-centers (D) having a concentration of retailing,
commercial, distribution and industrial activities, mainly aimed
at servicing a growing population.
- Improvements in transportation and telecommunications
have made several activities far more tolerant to distance, but
still dependent on accessibility. The urban land use pattern thus
tends to be far less coherent, more specialized and dispersed.
- A significant share of the land, notably nearby central areas,
is captured and not available on the real estate markets.
Governments, institutions, parks, industries and transport infrastructures
occupy a large part of most central areas and this ownership can
last for several decades (if not several centuries for historical
landmarks). This caused an imbalance in the price fixing mechanism
in central areas with less land available (thus higher prices) that
has favored urban sprawl.
