Delhi's Choking Challenge: GRAP Stage 2 Kicks In as Air Quality Plummets to 'Very Poor'

Delhi finds itself once again battling a familiar foe: rapidly deteriorating air quality. As the city's Air Quality Index (AQI) plunged into the 'very poor' category, authorities swiftly implemented Stage 2 of the Graded Response Action Plan (GRAP) to stem the tide of escalating pollution. This crucial step comes as a stark reminder of the persistent environmental challenges faced by the National Capital Region.

The Central Commission for Air Quality Management (CAQM) confirmed the activation of GRAP Stage 2, urging all relevant agencies to enforce the prescribed restrictions with immediate effect.

The decision was not taken lightly; the AQI had hovered dangerously close to the 300-mark for days, with readings consistently indicating a 'very poor' status – a significant health risk for residents.

Under GRAP Stage 2, a range of stringent measures come into play. One of the primary targets is construction and demolition activities.

While essential infrastructure projects are exempt, a broad prohibition on such work aims to reduce dust and particulate matter. Furthermore, the use of diesel generator sets is largely banned across the NCR, except for emergency services, reflecting a push towards cleaner energy sources.

Transportation also faces significant adjustments.

Parking fees are likely to see an increase to discourage private vehicle use, encouraging a shift towards public transport. To support this, bus and metro services are expected to be augmented, providing more frequent and accessible options for commuters. Authorities are also intensifying efforts to maintain clear roads, with mechanical sweeping and water sprinkling becoming more frequent to suppress road dust.

The 'very poor' air quality is not just a statistical anomaly; it poses tangible health threats.

Medical experts warn of heightened risks for individuals with respiratory ailments, cardiovascular diseases, and even healthy people experiencing symptoms like coughing, shortness of breath, and irritation in the eyes and throat. Children and the elderly are particularly vulnerable during such periods.

Environmental agencies attribute the sudden dip in air quality to a combination of factors.

Unfavorable meteorological conditions, including calm winds and low temperatures, trap pollutants close to the surface, preventing their dispersion. Additionally, local emission sources, vehicular exhaust, industrial output, and agricultural stubble burning in neighboring states continue to contribute significantly to Delhi's toxic air blanket.

The CAQM has called for strict enforcement of existing regulations against open burning of waste and illegal industrial operations, particularly in non-industrial areas.

As Delhi braces for the colder months, which often coincide with peak pollution levels, the implementation of GRAP Stage 2 serves as a critical intervention.

Its effectiveness hinges on widespread public cooperation and rigorous enforcement by government agencies. Residents are advised to take necessary precautions, monitor air quality alerts, and limit outdoor exposure, especially during peak pollution hours, to safeguard their health against the invisible enemy that descends upon the capital each year.
