On November 15th, 2023, Delhi and its surrounding areas were gripped by a severe air pollution crisis, with air quality plummeting into the ‘severe’ category. Drone footage captured from the Anand Vihar area starkly revealed the thick layer of smog enveloping the National Capital Region (NCR), highlighting the gravity of the ongoing environmental challenge.
The Air Quality Index (AQI) in various parts of Delhi soared to hazardous levels, raising serious concerns about public health and safety. According to Swiss air technology company IQAir, AQI readings in some areas reached alarmingly high figures, ranging from 800 to over 1,100. Anand Vihar, Dwarka-Sector 8, and Vasant Vihar’s Block C recorded AQIs of 1,105, 1,057, and 1,041, respectively. These figures were based on data collected from government monitoring stations and IQAir’s own sensors, underscoring the critical state of air quality in the city.
In response to the deteriorating air quality, the Graded Response Action Plan (GRAP) Stage III restrictions were put into effect. GRAP outlines four stages for addressing Delhi’s air pollution: Stage I (‘poor’), Stage II (‘very poor’), Stage III (‘severe’), and Stage IV (‘severe plus’). Stage III restrictions include a ban on non-essential construction and demolition activities, closure of stone crushers, and a prohibition on BS-III petrol and BS-IV diesel vehicles.
The Central Pollution Control Board’s (CPCB) Sameer app also recorded an overall AQI of 413, classifying the air quality as ‘severe.’ This underlined the intensity of the pollution impacting the residents of Delhi and its surrounding areas. If the pollution levels escalate further, Stage IV measures will be implemented, including a ban on inter-state buses (except electric and CNG), suspension of mining activities, and a shift to online classes for younger students. Additionally, daily water sprinkling on major roads will be enforced to reduce dust and pollutants in the air.
The alarming situation in Delhi serves as a stark reminder of the urgency to tackle air pollution. The persistent smog and high AQI readings pose a serious threat to public health, emphasizing the need for robust and comprehensive measures to address the root causes of the crisis. Collaborative efforts from government agencies, industries, and citizens are crucial to mitigate the impact of air pollution and create a healthier environment for all.
