Delhi has once again claimed the dubious title of the world's most polluted city, particularly following the recent Diwali celebrations. This year, despite a government ban on firecrackers intended to curb air pollution, the city's Air Quality Index (AQI) soared to alarming levels, peaking at 388 in some areas. The spike in pollution levels has raised serious health concerns for its 33 million residents, many of whom chose to ignore the ban in favour of cultural traditions.
Diwali Celebrations and Pollution Spike
On November 1, just after Diwali, Delhi's AQI was recorded at a hazardous 359, categorizing the air quality as "very poor." Monitoring stations reported PM2.5 levels reaching an astonishing 900 micrograms per cubic meter - far exceeding the safe limit of 60 micrograms. This marked a stark contrast to last year's relatively clearer skies during Diwali, when the AQI was recorded at 218 due to favourable weather conditions.
The combination of firecracker use, adverse weather, and ongoing stubble burning from neighbouring states has created a toxic smog that blankets the city every year during this festive period.
Despite the ban on firecrackers that extends until New Year’s Day, enforcement has proven challenging. Many residents openly defied the restrictions, citing cultural significance as a primary reason for their actions. As one local said, "It's our tradition, and we can't let go of it easily." This sentiment reflects a broader tension between cultural practices and environmental health.
Government Response and Public Health Concerns
In response to the escalating pollution levels, Delhi's government activated Stage II of its Graded Response Action Plan (GRAP), which includes halting construction activities and limiting diesel generator use. Mobile smog guns have been deployed across the city to spray water on roads and mitigate dust. However, these measures seem insufficient against the backdrop of widespread non-compliance with firecracker bans.
Doctors have described Delhi’s air pollution as akin to "slow poison," with significant health implications for vulnerable populations such as children and the elderly. Long-term exposure to such hazardous air quality increases risks for respiratory diseases like asthma and bronchitis. The Air Quality Life Index 2024 report indicates that persistent pollution is reducing life expectancy for Delhi's residents.
The Blame Game
As pollution levels rise, politicians have engaged in a blame game rather than taking collective responsibility for addressing the crisis. Factors contributing to Delhi's air quality issues include vehicular emissions, construction dust, and agricultural stubble burning. Yet leaders often deflect blame onto each other instead of implementing effective solutions or enforcing existing bans rigorously.
Delhi Environment Minister Gopal Rai highlighted that while efforts were made to control firecracker use this year - organizing 377 enforcement teams and collaborating with local organizations - compliance remained low. Reports indicated that neighborhoods across east and west Delhi saw widespread violations of the ban.
A Call for Collective Action
The ongoing air quality crisis in Delhi underscores the need for collective action from both authorities and residents. While cultural practices are important, they must be balanced with urgent public health considerations. The Supreme Court has emphasized that "Delhi cannot be made to go through this hazardous period every year," calling for systemic changes rather than temporary fixes.
As Delhi grapples with its air quality crisis post-Diwali, it is clear that without a concerted effort from all stakeholders - government officials, community leaders, and residents - the city will continue to struggle with its notorious pollution levels. The time has come for meaningful dialogue and action that respects both tradition and health.
