Urban life cycle
● Urban systems rise and fall according to
Urbanisation
the spatial behaviour of urban actors, who
are motivated by successive combinations
of changing exogenous variables, such as
demographics, politics, social values and
Reurbanisation Suburbanisation
technology (van den berg et al.1982).
● Studying a sample of functional urban
regions (furs) in the period 1950-1975, the Disurbanisation
authors identify four stages of
development.
Fig: urban life cycle
Urbanisation
● The stage of urbanisation runs parallel to the process of industrialization
● Masses of migrants coming from rural areas in search of jobs to the cities
● High priority for economic growth
● Large-scale industries and development of local public transport
● Urban functions, such as residential, working, shopping and transport, are all concentrated in the core
Suburbanisation
● Suburban municipalities find their population growing fast
● Rise in prosperity due to economic growth, the increasing car- 22 ownership
● Huge commuter flows between suburbs and the core
● Migrants continue to be oriented to the core not only for work, but they also rely on it for the higher-order services
such as hospitals, theatres, cinemas, etc
● Unbalanced traffic flows, congestion in the inner cities
Disurbanisation
● The entire metropolitan area is losing population and employment because of
rapid out-migration
● Higher rents and living costs make the minor towns relatively more attractive.
● Face the problems and consequences of rising unemployment, deteriorating
facilities and services, social disease and exclusion and, particularly in the central
cities, public deficits created by their shrinking tax bases.
● As a result of urban decay, urban regions have been increasingly compelled to
behave in a logic of competition to avoid the reaching of a situation of permanent
decline.
Reurbanisation
● Reurbanisation occurs when the shares of the population and employment in the
core with respect to those in the entire agglomeration increase again.
● Core population and employment will only show modest quantitative growth
● New flows of financial means, new opportunities of employment
● Revitalisation and deconcentration can go side by side, and are not mutually
exclusive
● Revitalisation has accelerated the growth of employment for well-trained
individuals, far outpacing the job opportunities for the unskilled and low-skilled.
Cont.
Mobility
● urban mobility refers to all aspects of
movement in urban settings. It can include
modes of transport, such as walking, cycling,
and public transit, as well as the spatial
arrangement of these modes in a built
environment.
Conclusion
In short an urban policy aimed to let the city be reurbanised has thus to pursuit:
● High economic potential: the creation of a satisfactory amount of jobs and income is of absolute importance;
● Improvements in quality of the living/working environment;
● Better accessibility of the city in terms of market potentials;
● A balanced social distribution of the effects;
● Community participation.
