The continuous decline in air quality in Delhi is a major cause for concern, especially during the winter season. Once again, the air quality is expected to fall into the ‘very poor’ category this year, primarily due to stubble burning in neighboring states. Each year, after the harvest, farmers in Punjab, Haryana, and Uttar Pradesh burn crop residue, releasing massive amounts of pollution that spread to Delhi and surrounding areas.
Despite several government efforts to curb stubble burning, the issue persists due to limited resources and lack of awareness. The particles released from stubble burning, such as PM2.5 and PM10, directly enter Delhi’s atmosphere, contributing to the formation of smog. So far, over 3,300 instances of stubble burning have been recorded this year, further deteriorating the air quality in the capital.
Local pollution also contributes to Delhi’s worsening air, with emissions from vehicles, dust from construction activities, and industrial pollution being the main culprits. Additionally, Delhi’s geographical location worsens the situation, as wind speeds slow down during winter, causing the pollution particles to remain suspended in the atmosphere.
The declining air quality has a direct impact on the health of Delhi’s residents, particularly the elderly, children, and those already suffering from respiratory issues. Prolonged exposure to pollution increases the risk of asthma, heart disease, and respiratory infections.
The government has taken various steps to address the problem, such as the odd-even traffic scheme, temporary bans on construction activities, and the use of anti-smog guns. Efforts are also being made to promote electric vehicles and strengthen public transportation. However, unless stubble burning is completely stopped in neighboring states and strict actions are taken against industrial pollution, these measures will only serve as short-term solutions.
A permanent solution to this problem is possible only if governments, farmers, industries, and the public work together. It is also essential to promote new technologies and resources to control pollution effectively.
