26.1 Introduction
Indian firms/industries have expanded very
rapidly in the last 30years, especially in
urban areas. Rapid growth in industrialisa-
tion is leading to many environmental issues,
including emission of uncontrolled pollut-
ants (CPCB, 2010). The emissions of vehi-
cles, municipal solid waste dumping sites,
real estate development, e‐waste processing
sites, destruction of forests, and land degra-
dation due to urbanisation are other sources
of pollution. Several industries established
near or in urban areas are polluting the envi-
ronment heavily. These are aluminium (Al)
and zinc (Zn) smelter industries, cement,
chlorine (Cl), copper (Cu) smelters, fertiliser,
iron and steel industries, distillery indus-
tries, oil refineries, pharmaceuticals and pet-
rochemicals, and pulp and paper industries.
In India, urbanisation has witnessed un-
precedented growth over the past 40 years.
During the last 50 years, the urban popula-
tion of India has grown nearly five times
(around 400 million people live in cities, in
sharp contrast to 60 million in 1947). About
140 million people will move to the cities by
2020 in India, and another 700 million by
2050. The number of Indian megacities will
increase from the current three (Mumbai,
Delhi, and Kolkata) to six (including Bangalore,
Chennai, and Hyderabad) by 2021. That
increasing population results in rapid con-
sumption of energy and other resources,
which is contributing to urban pollution.
Indian urban areas contain high levels of cri-
teria pollutants (e.g. particulate matter, SO
2
,
and NO
x
), greenhouse gases, ozone precur-
sors, and aerosols. The State of World Cities
Report (2012) shows that Mumbai and
New Delhi perform weakly on economic and
environmental dimensions. Thus, Indian cit-
ies are growing in an unsustainable manner
compared to other global cities, like Vienna
and Tokyo (Table 26.1).
26.2 Issues Related
to Urban Pollution in India
The environmental issues are unplanned
settlements, waste management, natural dis-
aster preparedness, traffic management, and
degradation and pollution of water and land
resources and air quality. Vegetation clear-
ance, drainage channel modifications, and
inappropriate agricultural practices cause
increased water erosion, which often creates
increased pollutant transport (Arora and
Reddy, 2013). Alarming levels of particu-
late matter are reported in urban areas of
India due to ever‐increasing traffic, growing
energy consumption, unplanned urban and
industrial development, and the high influx
