Delhi’s air pollution crisis: Government pushes for artificial rain to save the city
Air quality is primarily measured using the Air Quality Index (AQI), which considers five major pollutants: particulate matter (PM10 and PM2.5), nitrogen dioxide (NO2), sulfur dioxide (SO2), carbon monoxide (CO), and ozone (O3). The AQI scale ranges from 0 to 500, with higher values indicating more polluted air.

Vehicle Emissions
Delhi is home to over 11 million vehicles, contributing significantly to air pollution. Vehicles emit harmful gases like NO2, CO, and particulate matter, which exacerbate Delhi's air quality issues.
To mitigate vehicle emissions, the Delhi government has implemented various measures, such as promoting public transportation, encouraging carpooling, and phasing out older vehicles.
Industrial Activities
Industrial units, particularly those in the National Capital Region (NCR), contribute to air pollution through emissions from power plants, manufacturing units, and construction activities.
Regulations and strict enforcement are crucial to control industrial emissions. Additionally, promoting cleaner technologies and renewable energy sources can help reduce pollution from industrial activities.
Crop Residue Burning
During the winter months, farmers in the neighboring states of Punjab and Haryana burn crop residue to prepare their fields for the next sowing season. This practice releases vast amounts of smoke and particulate matter into the atmosphere, exacerbating Delhi's air quality crisis.
Educating farmers about alternative methods for managing crop residue, such as mechanical straw management and Happy Seeder technology, can help reduce this practice.
Addressing Delhi's air quality issue requires a multi-pronged approach, involving both short-term and long-term strategies. By understanding the air quality levels and their impacts, residents can take necessary precautions to protect their health. Moreover, collective efforts from individuals, industries, and policymakers are essential to improve Delhi's air quality and create a healthier, more sustainable environment for its residents.
