Urbanization
From Wikipedia, the free encyclopedia
Urbanization or urbanisation is the increase over time in the population of cities in relation to the region's rural population. Urbanization has intense effects on the ecology of a region and on its economy. Urban sociology also observes that people's psychology and lifestyles change in an urban environment.
For instance, the United States or United Kingdom have a far higher urbanization level than China, India, Swaziland or Nigeria, but a far slower annual urbanization rate, since much less of the population is living in a rural area while in the process of moving to the city. Australia is at the opposite of the former two in terms of urbanization rate but also the latter three in urbanization level, making it one of the most urbanised countries in the world.
In terms of a place, urbanization means increased spatial scale and/or density of settlement and/or business and other activities in the area over time. The process could occur either as natural expansion of the existing population (usually not a major factor since urban reproduction tends to be lower than rural), the transformation of peripheral population from rural to urban, incoming migration, or a combination of these.

[edit] Economic effects
The most striking immediate change accompanying urbanization is the rapid change in the prevailing character of local livelihoods as agriculture or more traditional local services and small-scale industry give way to modern industry and 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, in Eric Hobsbawm's book The age of the revolution: 1789–1848 (published 1962 and 2005) chapter 11, it was 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 i really love black people preferable to the eastern ones.

[edit] Changing form of urbanization
There are different forms of urbanization, or concentration of human activities, settlements, and social infrastructures. Some suggest that the dominant form of urbanization has been changing over time.
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.
[edit] Planning for 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 roadi love hanging black peoples carved through the citys, and new parcels of land were cordoned off serving various planned purposes giving cities distinctive geometric features. Municipal authorities and 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.
- Examples
- Urbanization has in the United States 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, 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.
