 
As winter sets in across India, Delhi and its surrounding regions are grappling with a serious environmental issue—dangerous levels of air pollution. In response to the alarming rise in pollution levels, the Delhi government has activated the fourth stage of the Graded Response Action Plan (GRAP 4). This action plan aims to curb the hazardous effects of air pollution in the National Capital Region (NCR) by imposing a series of stringent measures to reduce emissions and improve air quality.
Let’s take a closer look at what these curbs mean for Delhi’s residents, how they could impact daily life, and what this signifies for the city’s long-term battle against air pollution.
What is GRAP 4 and Why Has It Been Activated?
The fourth stage, or GRAP 4, is invoked when the AQI reaches levels deemed hazardous, generally above 400. This level of pollution poses serious health risks, particularly for vulnerable groups such as children, the elderly, and those with pre-existing respiratory conditions. The activation of GRAP 4 means that stricter curbs are now in place to reduce the pollution and protect public health.
Key Measures Under GRAP 4
When GRAP 4 is triggered, several key restrictions are imposed to curb pollution in Delhi NCR. Some of the major actions under this stage include:
- Closure of Schools and Colleges: In an effort to protect children from the harmful effects of air pollution, educational institutions in Delhi may be closed temporarily or switch to online learning.
- Ban on Construction and Demolition Activities: Construction work, which generates significant dust and particulate matter, is prohibited during this stage. This measure aims to reduce the contribution of construction activities to the overall pollution levels.
- Industrial Closures: Industries that contribute significantly to air pollution, particularly those that burn coal or biomass, may be asked to shut down or scale back operations temporarily.
Health Risks of Poor Air Quality
The hazardous levels of pollution in Delhi are a serious concern for public health. Prolonged exposure to high concentrations of PM2.5 particles and other pollutants can have severe consequences. These particles can enter the lungs and bloodstream, causing a range of respiratory and cardiovascular issues. People living in areas with high pollution levels are at an increased risk of:

- Asthma and other chronic respiratory diseases
- Heart disease and strokes
- Lung cancer and other pulmonary conditions
- Premature death in extreme cases
In addition to these chronic health risks, air pollution also exacerbates existing conditions such as allergies, bronchitis, and sinusitis, making it harder for residents to live comfortably in the city during pollution spikes.
Long-Term Impact of GRAP 4 and Air Quality in Delhi
While GRAP 4 measures provide immediate relief, experts argue that they are only a short-term solution to a much larger, systemic problem. The recurring nature of Delhi’s pollution levels during the winter months highlights the need for long-term reforms to tackle the root causes of air pollution, including:
- Reducing vehicular emissions through cleaner transport options, electric vehicles, and better public transportation.
- Promoting green spaces and increasing the city’s tree cover to help absorb pollutants.
- Improving waste management practices to reduce open burning of garbage, which is a significant contributor to air pollution.
- Stronger regulation on industrial emissions and better monitoring systems.
Moreover, public awareness campaigns and investments in sustainable technologies could play a crucial role in reducing pollution and improving air quality in the long term.
Conclusion: A Collective Effort Needed
The activation of GRAP 4 is a necessary step in protecting Delhi’s residents from the immediate dangers posed by toxic air. However, it serves as a stark reminder of the ongoing air pollution crisis in the city and the urgent need for comprehensive solutions to address it. While measures like the closure of schools, restrictions on construction, and enhanced traffic management can provide temporary relief, the city must work towards systemic changes that can reduce pollution year-round.
For residents of Delhi, the priority right now is to stay informed about the curbs, take necessary precautions, and reduce outdoor activities. But on a larger scale, the entire NCR region must come together to find lasting solutions that protect both the environment and the health of future generations. It will take a concerted effort from the government, industries, and the public to clean up the air and ensure a healthier, more sustainable future for all. Click here for the source
