Cities, the engines of economic growth create innovation, provide
employment opportunities, education and health services, while also serving as a market for
industrial and agricultural products. Availability of various social and economic services with a
network of infrastructure is an added incentive of these cities. Here, it is worth mentioning that
authors like Pirenne (1969), Adam (1976), Malthus (1986), and Weber (1958) emphasized
the involvement of factors like commerce, manufacturing and demographic shifts,
necessary for the growth of cities and economic advancement. According to the United Nations
Reports of 1996 and 2002, countries with comparatively lower degree of urbanization, which
was around 40% as in Africa and Asia, will reach to an estimate of 54% by the year
2025. Besides this, in urban areas, economic opportunities for the people appear to be better
as compared to rural areas. Therefore, urban areas have become attractive for people from
less advantageous regions of the country.
Another important factor for the people to move towards urban centers is
industrial modernization, which forces people to shift towards urban localities which have
a comparative advantage in relation to agricultural sector of rural areas. This argument is
easily supported in case of Pakistan by the current Pakistan's Federal Budget 2008-09, which
clearly indicates incentives provided to industries, which is a phenomenon of urban locations.
It is often observed and Fan et al. (2005) also pointed out that government policies
regarding investment, taxation and provision of subsidies are tilted towards urban settlements.
This creates an additional demand for resources for the growing population and
increased level of economic activity in the urban areas. McGranahan et al. (2004), in their work related to the environmental issues, highlighted the fact that demand for land in order to
build residence, transport, industries and disposal of urban waste have risen around the cities. |
