In the past two centuries, urban growth has
increased at a rapid pace, mainly driven by
the demographic impact of industrialization.
Besides urban growth, effects of
industrialization have likewise intensified
urban shrinkage (decrease).

Cities of the industrial age have:
experienced unprecedented economic
crises followed by waves of out-migration;
suffered from violent destruction, made
possible by the mechanization of war;
they have been drained by
suburbanization driven by an industrialized
building sector and increasing private car
ownership;
they have undergone processes of
deindustrialization followed by losses of
workplaces and population.

With its dependence and traditional center of the automotive industry (companies based General Motors, Ford and Chrysler), the Detroit area is more vulnerable to economic cycles than most large cities.

A rise in car manufacturing using robot technology, inexpensive labor in other parts of the world, and increased competition has led to a transformation of certain types of jobs in the region.
Economy is currently in a prolonged dead spiral: Houses for close, then abandoned, neighbourhoods died.
Accelerated by recession. Deindustrialisation.
Increasing unemployment rate in the metropolitan Detroit
Recently local government seeks to demolish abandoned homes, re-zone land use

reports that a recent landmark survey has found
that a third of Detroit’s residential parcels are
either vacant lots or abandoned homes.
Results portray a city of
contrasts: deep in distress in
many areas, but surprisingly
strong in others.
The survey, found more than
30,000 vacant residential
structures, with more than
10,000 of them open to
trespass and in dangerous
condition.

A mysterious series of
accidents led this would-be
tourist town to go unused
upon its completion.
Further, regional beliefs also
kept the abandoned
settlement from demolished
- for fear of angering spirits
dwelling in the complex.

Despite the scarce population, the town is a reminder of the economic downturn and how easy it is for towns to be abandoned.

Consequencies: As a result, the construction sector, encouraged by the residential-infrastructure tandem, steadily increased its share of the Spanish GDP.

‘Current trends in population growth
and global environmental change will
result coming decades to
◦ population displacements,
◦ forced migrations, and
◦ abandonment of settlements
on scales previously unseen.’
McLeman, 2011:

Development of Artificial LandPotential for environmentally related migration is rising.
Population growth rates are highest in regions where are acute:
• resource depletion,
• land degradation,
• and the expected impacts of
anthropogenic climate
change.
As the number of settlements experiencing a heightened state of vulnerability grows, increasing numbers of people will undertake adaptive migration. In some locations this will lead to population decline
