Everything about Urban Decay totally explained
Urban decay is a process by which a
city, or a part of a city, falls into a state of disrepair. It is characterized by
depopulation,
economic restructuring, property abandonment, high
unemployment, fragmented families, political
disenfranchisement,
crime, and desolate and unfriendly urban landscapes.
Urban decay was associated with Western cities, especially
North America and parts of
Europe during the 1970s and 1980s. During this time period, major changes in global economies,
transportation, and government policies created conditions that fostered urban decay.
The effects of urban decay run counter to the development patterns found in most cities in Europe and countries outside of North America, where
slums are usually located on the outskirts of major metropolitan areas while the
city center and
inner city retain high
real estate values and a steady or increasing population. In contrast, North American cities often experienced an outflux of population to city
suburbs or
exurbs, as in the case of
white flight. This trend has started to reverse in some cities, where affluent parts of the population have moved back into erstwhile blighted areas (see
gentrification).
There is no single cause of urban decay, though it may be triggered by a combination of interrelated factors, including
urban planning decisions,
poverty, the development of
freeways and railway lines,
suburbanisation,
redlining, immigration restrictions, and
racial discrimination.
Background
infrastructure,
transportation and space. Urban areas offer the widest variety of opportunities for education and financial betterment. They are the meeting places where business is conducted and goods are exchanged. They are the ports of entry for immigrants and the seats of power for governments. Urban places are held together by the human desire to form societies, celebrate culture and establish meaningful social relations. Cities are the essential element of almost all
civilizations. The word
civilization shares the same root as
city.
During the
Industrial Revolution, people moved from the countryside into cities to find employment in the manufacturing sector. Industrial manufacturing was largely responsible for the population boom cities experienced during this time period. However, subsequent economic change left many cities vulnerable. Various studies, including the Urban Task Force (DETR 1999), the Urban White Paper (DETR 2000), and a study of Scottish cities (2003) have argued that areas of industrial decline – with its legacy of high unemployment, poverty, and a decaying physical environment (sometimes including contaminated land and obsolete infrastructure) – prove "highly resistant to improvement".
Changes in transportation (specifically the private motor car) eliminated some of the cities' advantages. With the end of World War II in particular, many political decisions were employed that favored suburban development that further encouraged suburbanisation. Such decisions have drawn the financial resources from the cities in favour of providing infrastructure for remote suburban areas.
Racial discrimination, in this context known as "
white flight" in the
United States, also played a part, as many chose to abandon cities and take part in an
urban sprawl.
After World War Two, Western economies lifted tariffs and
outsourced most
manufacturing. During the change from a manufacturing to a service-based economy, private motor transportation was growing in availability. In the United States, the federal government aided the suburbanization process by mandating
discriminatory lending practices through the FHA in the form of
redlining. Later, under president
Dwight D. Eisenhower, urban centers were drained further through the building of the
Interstate Highway System. In North America this shift has manifested itself in
strip malls, suburban retail and employment centers, and very low-density housing estates. Large areas of many northern cities in the United States have experienced population decreases and a degradation of urban areas. Inner-city property values declined and economically disadvantaged populations moved in. In the U.S., the new inner-city poor were often African-Americans that migrated from the South in the 1920s and 1930s. As they moved into traditional white European-American neighborhoods, ethnic frictions served to accelerate flight to the suburbs. In
Western Europe the experience differs in that the effect was often unknowingly assisted by public sector policies designed to clear 18th and 19th century slum areas and movements of people out into state subsidised lower density suburban housing.
On continental Europe and Oceania the historical core of major cities usually remains relatively affluent; it's generally the inner city districts and the edge of town suburbs made up of single-class state subsidised housing, such as the French "cités" and British "
council estates", which suffer the worst decay and blight. Due to higher population densities in Europe, economics dictates that extremely low-density housing would be impractical.
Examples of decay
The
car manufacturing sector was the base for
Detroit's prosperity and employed the majority of its residents. When this industry began relocating outside of the city, it experienced massive population loss with associated urban decay, particularly after the
1967 riots. In 1950 the city's population was (according to the U.S. census) around 1.85 million; by 2003, this had declined to 911,000, a loss of nearly 940,000 people (52%).
Britain experienced severe urban decay in the 1970s and 1980s. Major cities like
Glasgow in Scotland, the towns of the South
Wales valleys, and the major English cities like
Birmingham,
Manchester,
Liverpool,
Newcastle, and the East of
London all experienced population decreases with very large areas of 19th century housing experiencing market price collapse.
Large
French cities are often surrounded by decayed areas. While the city center tends to be occupied mostly by middle- as well as upper-class residents, the city is often surrounded by very large mid to high-rise housing projects. The concentration of poverty and crime radiating from the developments often cause the entire suburb to fall into a state of urban decay as more affluent citizens seek housing in the city, or further out in semi-rural areas. In early November 2005, the decaying northern suburbs of Paris were the scene of severe
riots sparked in part by the substandard living conditions in public housing projects.
Remedy
The main responses to urban decay have been through positive public intervention and policy, through a plethora of initiatives, funding streams, and agencies, using the principles of
New Urbanism (or through
Urban Renaissance, its UK/European equivalent). The importance of
gentrification shouldn't be underestimated and remains the primary means of a 'natural' remedy.
In the United States, early government policies included "
Urban renewal" and building of large scale housing projects for the poor. Urban renewal demolished entire neighbourhoods in many inner-cities; in many ways it was a cause of urban decay rather than a remedy Housing projects became crime infested mistakes. These government efforts are thought by many now to have been misguided. Some cities have rebounded in spite of these policy mistakes for multiple reasons. Today however with many people interested in moving back to the inner cities,
gentrification has renewed and restored some of these neighborhoods. Meanwhile some of the inner suburbs built in the 1950s and 60s are beginning the process of decay as those who are living in the inner city are pushed out due to gentrification.
In Western Europe, where land is much less in supply and urban areas are generally recognised as the drivers of the new information and service economies,
urban regeneration has become a quasi industry in itself, with hundreds of agencies and charities set up to tackle the issue. European cities have the benefit of historical organic development patterns already concurrent to the New Urbanist model, and although derelict, most cities have attractive historical quarters and buildings ripe for redevelopment. In the suburban estates and cités the solution is often more drastic with 1960/70 state housing projects being totally demolished and rebuilt in a more traditional European urban style, with a mix of housing types, sizes, prices, and tenures, as well as a mix of other uses such as
retail or
commercial. One of the best examples of this is in
Hulme,
Manchester, which was cleared of 19th century housing in the 1950s to make way for a large estate of high-rise flats. During the 1990s it was cleared again to make way for new development built along new urbanist lines. The area is held up as an excellent example of Urban Renaissance.
