'Severe' season in Delhi: GRAP III in force as air quality plummets

Air quality in India's capital has deteriorated to levels that trigger the highest alert under the Graded Response Action Plan. Seasonal factors such as low wind, temperature inversion and the burning of crop residues in neighboring states combine to raise concentrations of fine particulate matter and other pollutants. Health officials warn that prolonged exposure can aggravate respiratory conditions, increase hospital admissions and pose a risk to vulnerable groups such as children and the elderly.

The third level of the Graded Response Action Plan, known as GRAP III, requires a set of strict measures aimed at reducing emissions in the short term. Under this level, construction activities are halted, diesel generators are restricted, and the use of private vehicles that do not meet emission standards is limited. Public transport is encouraged, schools may be closed in the most affected zones, and industrial units are asked to switch to cleaner fuels where possible. These steps are designed to bring pollutant concentrations back within national safety limits.

Residents of Delhi are being advised to limit outdoor activities, especially during early morning and evening periods when pollution peaks. Authorities have set up real‑time monitoring stations and are providing daily alerts through mobile apps and media channels. The government says that the GRAP III activation will be reviewed daily and may be relaxed if air quality improves. Observers note that sustained policy action on waste management, vehicle emissions and regional cooperation will be essential to prevent future severe episodes.
