How the exam will ask it
पूर्व
- GRAP is enforced in Delhi-NCR by the Commission for Air Quality Management (CAQM).
- Stage I of GRAP is invoked when the Air Quality Index falls in the 'Poor' category.
- GRAP stages escalate with AQI category: Poor (I), Very Poor (II), Severe (III) and Severe+ (IV).
- GRAP is a graded, AQI-triggered set of emergency curbs rather than a permanent pollution law.
मुख्य
GS-III (Environment, pollution): Delhi-NCR's recurring air pollution is managed through the CAQM-enforced GRAP, whose stages are triggered by AQI categories. Its reactive, trigger-based design curbs peaks but not root causes, so the way forward is year-round source control (vehicles, dust, industry, biomass burning) with coordinated action across NCR states.
