n Urbanization is one of the most important
geographic phenomena in today’s world. The United
Nations Center for Human Settlements (UNCHS)
has concluded that the growth of cities and the
urbanization of rural areas are now irreversible due
to the global shift to technological, industrial, and
service-based economies. The proportion of the
world’s population living in urban settlements is
growing at a rapid rate, and the world's economic,
social, cultural, and political processes are
increasing being played out within and between the
world’s system of cities and towns.
