Case study to improve air quality in Delhi

1. Case study 1 : to improve the air quality in delhi BY JOE ARYA R, GRADE 7 PRESIDENCY SCHOOL BANGALORE SOUTH

2. Ways to improve air quality index : 1. VEHICULAR AND INDUSTRIAL EMISSIONS Imposing strict emission norms in industries mainly to cut down emissions of particulate matter (PM10 ), Sulphur dioxide (SO2) and oxides of nitrogen (NOx). The concentration of PM emissions should not exceed the prescribed standard of 150 mg/Nm3 according to Central Pollution Control Board. Restricted entry of heavy trucks into Delhi (except essential commodities) Construction works should be restricted. Close brick kilns, hot mix plants, stone crushers.

3. VEHICULAR AND INDUSTRIAL EMISSIONS Maximize power generation from natural gas to reduce generation from coal. To encourage public transport by increasing bus and Metro services with differential rates. Mechanized cleaning of road and sprinkling of water should be done frequently. Stopping the usage of diesel generators. Impose a complete ban on the sale and purchase of firecrackers.

4. 2. GEOGRAPHICAL LOCATION- Landlocked The capital city lies to the north-east of the Thar Desert, to the north-west of the central plains and to the south-west of the Himalayas. The coastal winds are trapped in this region where the air pressure pushes from one direction, and with the inability to escape quickly, the particulate matter accumulates over the northern plains. The accumulation and entrapment affect not only Delhi, but the entire expanse between Punjab in the west to West Bengal in the east. This region acts as a “bowl” that collects pollutants, with only a narrow outlet for it to escape. To avoid this, the governments of neighbouring states like Punjab, Haryana and Uttar Pradesh should work together to make the air clean.

5. 3. Farming- stubble burning Stubble burning can be done by PUSA BIO DECOMPOSER - which is a low cost microbial bio- enzyme that can decompose crop residue, including stubble from crops. Pusa bio Decomposer is prepared with a mix of seven different fungi, which produce several digestive enzymes, including pectin, cellulose, and lignin.  These fungi tend to thrive at a temperature of 30 to 32 degrees Celsius, which is the ideal temperature that prevails at the time when paddy is harvested, and wheat crops are sown in the soil.
