Urbanization over the past 500 years [13] A global map illustrating the first onset and spread of urban centres around the world, based on. [14]From the development of the earliest cities in Indus valley civilization, Mesopotamia and Egypt until the 18th century, an equilibrium existed between the vast majority of the population who were engaged in subsistence agriculture in a rural context ...
Urbanization has many environmental consequences. In all urban areas there are numerous impacts on the environment such as air pollution, water pollution, etc. Excessive urbanization creates risks (fragilization of soils, pollution, plundering of natural resources) [6] Urbanization is one of the causes of the erosion of biodiversity.
Population growth and urbanization were driven by migration from overpopulated rural areas, even though the majority of jobs available were still in the agricultural sector. [7] The 17.2 percent of Korea's population that were urban dwellers in 1949 were attributed largely to the presence of rural migrants. [2]
With the increase in emissions from vehicles, this then can cause air pollution and degrades the air quality of an area. Suburbanization is growing which causes an increase in housing development, that then results in an increase in land consumption and available land. Suburbanization has also been linked to increases in natural resource use ...
Urbanization was fastest in the Northeastern United States, which acquired an urban majority by 1880. [2] Some Northeastern U.S. states had already acquired an urban majority before then, including Massachusetts and Rhode Island (majority-urban by 1850), [ 4 ] [ 5 ] and New York (majority-urban since about 1870).
Urban stream syndrome is a consistently observed trait of urbanization characterized by high nutrient and contaminant concentration, altered stream morphology, increased dominance of dominant species, and decreased biodiversity [29] [52] The two primary causes of urban stream syndrome are storm water runoff and wastewater treatment plant effluent.
A typical suburban development in the United States, located in Chandler, Arizona An urban development in Palma, Mallorca. Urban sprawl (also known as suburban sprawl or urban encroachment [1]) is defined as "the spreading of urban developments (such as houses, dense multi–family apartments, office buildings and shopping centers) on undeveloped land near a more or less densely populated city".
Drivers, processes, and impacts of sinking cities [1]. Sinking cities are urban environments that are in danger of disappearing due to their rapidly changing landscapes.The largest contributors to these cities becoming unlivable are the combined effects of climate change (manifested through sea level rise, intensifying storms, and storm surge), land subsidence, and accelerated urbanization.
