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).

INTRODUCTION

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.

ACTUAL LOCATION: DETROIT-MOTOR CITY FACTOR: DE-INDUSTRIALIZATION ‘Swiss cheese’ pattern of neighbourhood abandonment 800,000 out-migrants since 1950s;

In red colour: Surface parking lots and underutilized demolished building sites shown in red.

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.


14

ACTUAL LOCATION: DETROIT-MOTOR CITY FACTOR: DE-INDUSTRIALIZATION

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

Ruins of civilization – A dying city. Listed as the most dangerous city in USA


15

ACTUAL LOCATION: DETROIT-MOTOR CITY FACTOR: DE-INDUSTRIALIZATION 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.

reports that a recent landmark survey has found that a third of Detroit’s residential parcels are either vacant lots or abandoned homes.

That should give you a taste of what the show is like

to do something about the city’s plan to formally abandon these neighborhoods by turning them into something more fun and constructive http://www.digitaltrends.com/lifestyle/abandoned-parts-of-detroit-may-be-turned-into-a-zombie-theme-park/ 16


ABANDONEMENT BY WAR CONFLICTS AND HISTORICAL MEMORIES

17


ANCIENT LOCATION FACTOR: WAR/BELIC CONFLICTS

But in 2007 came to the town rebels brought violence and destruction against government troops, leaving Birao almost completely burned to the ground.

Only a few years ago Birao served as the capital of Vakaga, one of the 14 prefectures of the Central African Republic.

19

ANCIENT LOCATION FACTOR: WAR MEMORIES LOST

Abandoned Yugoslavia Monuments that look like they're from the Future: These structures were commissioned by former Yugoslavian president in the 1960s and 70s to In the 1980s, these monuments attracted millions of visitors per year. After the Republic dissolved in early 1990s, they were completely abandoned, and their symbolic meanings were forever lost.

MEMORIES FROM THE PAST Commemorate sites where â—Ś WWII battles took place, â—Ś Concentration camps stood.

Convey powerful visual impact to show the confidence and strength of the Socialist Republic.

San Zhi, Taipei (Taiwan)

ANCIENT LOCATION

Abandoned settlement on the outskirts / sububs

FACTOR: SOCIAL FEARFULNESS 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.

HOUSING BUBBLE STILL BURSTING IN SPAIN

VALDELUZ CITY (GUADALAJARA) •

Stop on the high speed rail

Built to house 30,000 people;

only 1,000 people took up residence.

SESEÑA (TOLEDO) Apartments selling: •

2008 - 221,000 €

2013 -65,000 € (markets floors below cost since March 2012)

Due to the economic downturn, never finished


23

PRESENT LOCATION VALDELUZ CITY

Not even entirely populated area Causes: Due to the changes in State Land Legislation: 1996–2008

FACTOR: UNSUSTAINABLE DWELLING SITES Our national currently cause – PRIORITY

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


24

‘YOUR HOPES MEET OUR HOPES MEET OURS EVERY DAY’

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

CONCLUSIONS

‘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:


PRESENT LOCATION FACTOR: POPULATION GROWTH Potential for environmentally related migration is rising.

Development of Artificial Land

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

PROCESS OF ABANDONMENT

‘In the context of the long time-scale, the abandonment of inhabited locations may be seen as just one stage in the ongoing cycle of human settlement and land use.’ Stage 1 Rising vulnerability Stage 2 Population decline

Cameron, 1993:

Stage 3 Abandonment


28

COMMUN FACTORS OF ABANDONEMENT

Overexploitation  Resource Depletion

(i.e. Coal)

Soaring housing prices or artificial land boom  Housing Oversupply OPINION As an architect, I think the old abandoned sites after the hegemony of the industrial age should be preserved as cultural heritage.
