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 ...
Modifications of the landscape and other abiotic factors contribute to a changed climate in urban areas. The use of impervious dark surfaces which retain and reflect heat, and human generated heat energy lead to an urban heat island in the center of cities, where the temperature is increased significantly. A large urban microclimate does not ...
The increasing population can lead to poor air quality and quality and availability of water. The growth of urbanization can lead to more use of energy which leads to air pollution and can impact human health. Flash flooding is another environmental hazard that can occur due to urban development.
Urban responses to global environmental change (e.g., urban strategies for climate change mitigation and adaptation). Consequences of urban responses to global environmental change. Additionally, the goals of UGEC include: creating multidimensional integrative perspectives; promoting parallel and comparative analysis across regions and themes;
Measures for urban sprawl in Europe: upper left the Dispersion of the built-up area (DIS), upper right the weighted urban proliferation (WUP). The term urban sprawl was often used in the letters between Lewis Mumford and Frederic J. Osborn, [17] firstly by Osborn in his 1941 letter to Mumford and later by Mumford, generally condemning the waste of agricultural land and landscape due to ...
Cities have a significant influence on construction and transportation—two of the key contributors to global warming emissions. [8] Moreover, because of processes that create climate conflict and climate refugees , city areas are expected to grow during the next several decades, stressing infrastructure and concentrating more impoverished ...
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.

As with most examples of rural flight, several factors have led towards China's massive urbanization. Income disparity, family pressure, surplus labor in rural areas due to higher average fertility rates, and improved living conditions all play a role in contributing to the flows of migrants from rural to urban areas.
