Evolution and assessment on China’s urbanization 1960–2010: Under-urbanization or over-urbanization?
There has been a significant transformation in the urbanization and economic growth in post-reform China. The nature and degree of urbanization is a subject of some controversy. 
URBANIZATION AND STREAM QUALITY IMPAIRMENT
A study was conducted in the Piedmont province of Maryland to determine if a relationship exists between stream quality and the extent of watershed urbanization. During the first phase of the study 27 small watersheds, having similar characteristics but varied according to land use, were investigated. 
Landscape change and the urbanization process in Europe
Urbanization is one of the fundamental characteristics of the European civilization. It gradually spread from Southeast Europe around 700 b.c., across the whole continent. Cities and the urban networks they formed were always an important factor in the development and shaping of their surrounding regions. 
Forced-Urbanization: The Alienation of Urbanization in China

Ecological Consequences of Urbanization of Uyo Capital City, Akwa Ibom State, Nigeria
