    In Delhi toady pollution is one of the most critical problems facing the public and concerned authorities. According to the World Health Organization (WHO), Delhi is the fourth most polluted city in the world in terms of Suspended Particulate Matter (SPM). The growing pollution is responsible for increasing health problems. the deteriorating environment is the result of population pressure and haphazard growth. Industrial development has been haphazard and unplanned. Only about 2-% of the industrial units are in approved industrial areas; the remainder are spread over the city in residential and commercial area Road transport is the sole mode of public transport; there has been a phenomenal increase in the vehicle population, which was increased from2 lackh in 1971 to 2 lakh in 1999. (NCT Fact Sheet Delhi, 1999).

    Pollution levels

    Ambient air quality - Data from continuous monitoring of air quality reveals that suspended particulate matter levels still far exceed stipulated standards, there is a significant downward trend as indicated in the following tables.

    According to a study by Delhi Pollution Control committee, noise levels in Delhi exceeds permissible levels in all areas except industrial areas. since noise is measured on a logarithmic scale, an increase of every 3-5 dBA has twice the effect on humans. Diesel generating sets and vehicles, particularly auto rickshaws, have been identified as major sources of noise pollution in Delhi.

    Air pollution - Due to phenomenal growth in the number of motor vehicles Delhi and power generation based on a fired power stations, total amount on coal fired power stations, total amount of pollutants received by the city is around 3000 tonnes as compared to 100 tonnes a decade ago. Sixty five percent of these pollutants are produced by motor vehicles. Annual average maximum, levels of SPM in Delhi's air has increased from 7.6 times the permissible limit in 1987 to 16.7 time in 1995.

    Industrial air pollution - The air pollution generated from industrial activity in Delhi is about 12% of total air pollution. More than 1,300 industrial units that were not allowed to operate under the MPD - 2001 norms have been closed. The 1991 reports by the National Environmental Engineering Research Institute (NEERI), Nagpur documents the amount of pollution that is contributed by different sectors in Delhi:

    In relative terms, the quantum industrial air pollution has decreased over the years. However, vehicular pollution has increased rapidly. The drop in share of domestic air pollution is due to the increased number of LPG connections in Delhi, which have replaced other forms of fuel.

    Noise levels in Delhi exceed permissible levels in all areas except industrial areas according to a study by the Delhi Pollution Control Committee. Since noise is measured on a logarithmic scale, an increase of every 3-4 dBA has twice the effect on humans. Diesels generating sets and vehicles, particularly auto rickshaws, have been identified as major sources of noise pollution of Delhi.

    Environment development and disasters

    Ecological imbalance created due to abuse and overuse of environmental services in the city has left very thin line between natural and man made disasters. The city is subjected to congestion and high density of population living in poor sanitary conditions. Poverty has mad ea large population live as squatters on the flood plains of the Yamuna, which are vulnerable to hazards like fires, floods and earthquakes. Apart from these, risks of violence, crime and road accidents take a big toll of life in the capital city of the country.

    The topography of the city has two main features - the Ridge and the river Yamuna. Although Delhi was built many times, these two natural boundaries were never transgressed. The Ridge was perceived (incorrectly) as an impenetrable area inhabited by extraordinary plants and fierce animals. The people of Delhi were fortunate to have both river as well as lush green forest. They coexisted with a vast number of beings from wolves to leopards to minute insect in perfect harmony. With the transfer of capital of India from Calcutta to Delhi during British times, developmental activities started in the city. The Ridge and the river started losing their natural state. The degradation of these two worsened when the city started developing across its natural two boundaries.

    Today the development continues defying city planning logics. Areas west of the Ridge have been colonized and the natural drainage pattern ate disturbed. Areas East of Yamuna which have been developed despite being low tying and prone to water logging and inundation, a re toady totally flood prone. The Ridge as lost its topographical continuity, having been blasted in many placed to build new colonies. Today only four small broken patches are left, one near Delhi University, a large one near Dhaula Kuan and two in South Delhi, one of which Sanjay Van is probably still the most pristine lost to artificial gardens and recreational parks, such as Buddha Jayanti Park and Mahavir Jayanti Park. The perfect balance and harmony of nature had been disturbed. Undergrowth which was home to many life-forms has been rampantly cleared.

    However, amazingly, despite all sorts of pressures like tree-falling, urbanization, industrialization, pollution, mining etc, the Ridge forest still services in those small patches. Equally surprising, it still sustains a myriad of life forms. The river Yamuna has turned more or less into a drain and does not carry clear fresh water any more. Why have we destroyed our natural heritage, the ridge and the river, and what are we leaving behind for future generations?

    Nature cannot take more abuse hence the degradation caused to the environment of the city has to respond in terms of its wrath. Floods in Delhi are not natures wrong doing, it is invariably the irresponsibility of the authorities and those who are totally insensitive to human life blinded by the haves and have-nots of economics. This is very clear from the recurring phenomenon of floods in the mighty river Yamuna and flash floods caused by rains due to chocked drains in Delhi.


    2003: Delhi won the US Department of Energy’s first ‘Clean Cities International Partner of the Year’ award for ‘‘bold efforts to curb air pollution and support alternative fuel initiatives’’.

    Figures prove this new freshness: Compared to 1997, carbon monoxide levels are down 32 per cent, sulphur dioxide levels, 39 per cent.

    TODAY, Delhi is a showpiece example of making air quality safe with its entire public transport fleet converted to Compressed Natural Gas (CNG) on a scale unparalleled anywhere else—80,000 CNG vehicles including 9,000 buses. Delhi has banned taxis, buses and auto rickshaws older than 15 years.

    The great vehicle explosion continues in Delhi. Yet, this rush of clean vehicles keeps the air relatively sparkling.

    The initiative was entirely driven by the judiciary pushing and prodding a reluctant government. Every step was a struggle till implementing agencies were threatened with contempt of court for their innovative excuses to not implement the CNG programme.

    Vehicle manufacturers quoted obnoxious figures for changing to a new technology. The Government of India dilly-dallied to modify the Motor Vehicles Act to include CNG in its ambit.

    Today, every Delhi politician claims credit for bringing in CNG.

    It started with a public interest litigation by the Centre of Science and Environment in 1996 that resulted in a series of Supreme Court orders, the major step being introduction of CNG for public transport in 1998.

    Instrumental in exposing government lies and charting a roadmap for the Centre was an independent committee set up by the Supreme Court—the Environment Protection Control Authority (EPCA), headed by Bhure Lal.

    In 2002, at one point, it seemed the CNG programme would be abandoned.

    There was no infrastructure to support court orders. The result was serpentine queues of auto rickshaws and buses at CNG stations, holding up commuters. Today, there are 110 CNG stations in Delhi.

    Autorickshaws were the first to convert once the government offered sales tax exemptions. If the government is willing, the toughest plans can take off even through smog and smoke.

    This question reminds me that I have to do more research into anthropocentric Global Warming hypotheses. Global Warming is a fact, but whether we're making any real impact on it, I'm not sure I know that if we are a significant factor, the only way to reduce our impact involves massive decreases in all aspects of the economy, from factory production to farming to transport. Maybe this would be one area where the fundies are right - we'd need at least 2/3 of the world's population to disappear to make things right.

    well everyone has contributed to global warming- just by doing regular human activities, so delhi like the rest of the world has contributed by over populated pollution, wrong disposal of waste, and whatever we humans do.
