The Urbanization of the World

The Urbanization of the World
________________________________________
Origin of Cities: Some Introductory Points

The City is a relatively recent form of social organization.
• Homo sapiens, the present human form has existed on earth for about 40,000 years, but cities have existed for less than 10,000 years.
• Jericho in about 7000 B.C. grew from village to a "city" of about 3,000
• 3,500-4,000 B.C. first large cities (population of about 25,000) were established in Mesopotamia.

A "city" refers to a place of relatively dense settlement -- dense enough so that city residents can not grow their own food. A city population, therefore, is always dependent upon its "hinterlands" to provide it with food. Not until agriculture developed could hinterlands provide food for their own populations and enough of a surplus to feed a city population. And in agricultural societies the surplus was so small that only a tiny proportion of an entire population could live in cities. Up until very recently -- about 200 years ago -- that proportion was limited to about 5% of an entire population. So cities existed, but there was no urbanization.
Urbanization refers to a process in which an increasing proportion of an entire population lives in cities and the suburbs of cities. Historically, it has been closely connected with industrialization. When more and more inanimate sources of energy were used to enhance human productivity (industrialization), surpluses increased in both agriculture and industry. Larger and larger proportions of a population could live in cities. Economic forces were such that cities became the ideal places to locate factories and their workers.

Urbanization of First World Societies

In the United States, about 5% of the population lived in cities in 1800, but about 50% of the population lived in cities by 1920. Throughout the 19th century, the US was urbanizing. The same was true for most European societies during the 19th century.

Today about 80% of the US population lives in cities and suburbs. Since no more than 100% of a population can possibly be urban, urbanization as a process is coming to an end.

Urbanization of Third World Societies




Compare Urbanization in the World's More Developed and Less Developed Societies



Notice that at mid-century only 17.8% of the population of Third World societies lived in cities, but in the fifty years since 1950 that percent has increased to over 40%. By the year 2030, almost 60% of Third World populations will live in cities. In just a few years the World will become predominately urban -- about 80-85 years after that happened in the United States.

The World's Population Will be Predominately Urban
by the Year 2005



There is a very big question related to Third World urbanization: Will it prove beneficial for people's lives? Much of Third World urbanization is the result of overpopulation in the countryside. In villages babies have been living and not dying. A husband and wife who farm 15 acres might have three sons and three daughters. All now live and grow up. But there is not land enough for them to have the farms they need to marry and raise a family. This lack of land for burgeoning rural populations forced them to leave the village and migrate to cities. They find a place to live in the favela's and shantytowns -- such as the one pictured below -- but often times they don't find productive employment.



Third World urbanization will be a beneficial social trend only if enough good jobs can be found for the rapidly growing population of Third World cities.

The city of Los Angeles is an example of urbanisation


Urbanization or Urbanisation (see difference in spelling) means the removal of the rural characteristics of a town or area, a process associated with the development of civilisation. Demographically , the term denotes redistribution of populations from rural to urban settlements.
Urbanization Today
The 2005 Revision of the UN World Urbanization Prospects report described the 20th century as witnessing "the rapid urbanization of the world’s population", as the global proportion of urban population rose dramatically from 13% (220 million) in 1900, to 29% (732 million) in 1950, to 49% (3.2 billion) in 2005. The same report projected that the figure is likely to rise to 60% (4.9 billion) by 2030.[1]

Urbanization rates vary across the world. The United States and United Kingdom have a far higher urbanization level than China, India, Swaziland or Niger, but a far slower annual urbanization rate, since much less of the population is living in a rural area.
• Urbanization in the United States has affected the Rocky Mountains in locations such as Jackson Hole, Wyoming, Telluride, Colorado, Taos, New Mexico, Douglas County, Colorado and Aspen, Colorado. The lake district of northern Minnesota has also been affected as has Vermont, the coast of Florida, the Birmingham-Jefferson County, AL area, the Pacific Northwest and the barrier islands of North Carolina.
• In the United Kingdom, two major examples of new urbanization can be seen in Swindon, Wiltshire and Milton Keynes, Buckinghamshire. These two towns show some of the quickest growth rates in Europe.
Urbanization Projections
According to the UN-HABITAT 2006 Annual Report, sometime in the middle of 2007, the majority of people worldwide will be living in towns or cities, for the first time in history; this is referred to as the arrival of the "Urban Millennium". In regard to future trends, it is estimated 93% of urban growth will occur in Asia and Africa, and to a lesser extent in Latin America and the Caribbean. By 2050 over 6 billion people, two thirds of humanity, will be living in towns and cities.
Economic effects

One of the last houses of the old Russian village of Lukeryino, most of which has been mostly demolished over the last 30 years to make way for 9-story apartment buildings of the growing city of Kstovo, such as the one in the background
Over the last few years urbanization of rural areas has increased. As agriculture, more traditional local services, and small-scale industry give way to modern industry the urban and related commerce with the city drawing on the resources of an ever-widening area for its own sustenance and goods to be traded or processed into manufactures.

Research in urban ecology finds that larger cities provide more specialized goods and services to the local market and surrounding areas, function as a transportation and wholesale hub for smaller places, and accumulate more capital, financial service provision, and an educated labor force, as well as often concentrating administrative functions for the area in which they lie. This relation among places of different sizes is called the urban hierarchy.

As cities develop, effects can include a dramatic increase in rents, often pricing the local working class out of the market, including such functionaries as employees of the local municipalities. For example, Eric Hobsbawm's book The age of the revolution: 1789–1848 (published 1962 and 2005) chapter 11, stated "Urban development in our period [1789–1848] was a gigantic process of class segregation, which pushed the new labouring poor into great morasses of misery outside the centres of government and business and the newly specialised residential areas of the bourgeoisie. The almost universal European division into a 'good' west end and a 'poor' east end of large cities developed in this period." This is likely due the prevailing south-west wind which carries coal smoke and other airborne pollutants downwind, making the western edges of towns preferable to the eastern ones.
Changing form of urbanization
Traditional urbanization exhibits a concentration of human activities and settlements around the downtown area. When the residential area shifts outward, this is called suburbanization. A number of researchers and writers suggest that suburbanization has gone so far to form new points of concentration outside the downtown. This networked, poly-centric form of concentration is considered by some an emerging pattern of urbanization. It is called variously exurbia, edge city (Garreau, 1991), network city (Batten, 1995), or postmodern city (Dear, 2000). Los Angeles is the best-known example of this type of urbanization.
Planning for urbanization

The construction of new towns by the Housing Development Board of Singapore, is an example of planned urbanization
Urbanization can be planned or organic. Planned urbanization, ie: new town or the garden city movement, is based on an advance plan, which can be prepared for military, aesthetic, economic or urban design reasons. Unplanned (organic) cities are the oldest form of urbanization. Examples can be seen in many ancient cities; although with exploration came the collision of nations, which meant that many invaded cites took on the desired planned characteristics of their occupiers. Many ancient organic cities experienced redevelopment for military and economic purposes, new roads carved through the cities, and new parcels of land were cordoned off serving various planned purposes giving cities distinctive geometric UN agencies prefer to see urban infrastructure installed before urbanization occurs. landscape planners are responsible for landscape infrastructure (public parks, sustainable urban drainage systems, greenways etc) which can be planned before urbanization takes place, or afterward to revitalized an area and create greater livability within a region.
New Urbanism
New Urbanism was a movement which started in the 1980s. New Urbanism believes in shifting design focus from the car-centric development of suburbia and the business park, to concentrated pedestrian and transit-centric, walkable, mixed-use communities. New Urbanism is an amalgamation of old-world design patterns, merged with present day demands. It is a backlash to the age of suburban sprawl, which splintered communities, and isolated people from each other, as well as had severe environmental impacts. Concepts for New Urbanism include people and destinations into dense, vibrant communities, and decreasing dependency on vehicular transportation as the primary mode of transit.

Urban Population
The majority of the human population moved into urban area, separate from nature, soon after the Industrial Revolution. Currently, less than 3 percent of the U.S. population lives or works on a farm while over 80 percent live or work in urban areas (Miller, 1997).
