PIB TrackerCAQM's PAVAN centre puts NCR pollution on one screen
The Environment Minister reviewed CAQM's new PAVAN command centre, which pulls more than 30 data streams - 111 monitoring stations, 2,300 industries, 3,200 construction sites - into alert-based enforcement, and said construction and demolition across NCR would halt from 5 to 20 November.
What happened
- Environment Minister Bhupender Yadav visited CAQM's new Integrated Command and Control Centre (I3C), named PAVAN - Platform for Air quality Vigilance and Analytics for NCR, and reviewed its technology and operational readiness.
- PAVAN-I3C integrates more than 30 APIs and data streams, with data from 111 CAAQMS, over 2,300 industries, more than 3,200 active construction sites and traffic congestion hotspots.
- Its modules include OCEMS stack data (PM, SO2, NOx, CO); crop-residue burning data from IARI, ISRO and FIRMS compared with the previous six years; landfill feeds from Okhla, Bhalswa, Ghazipur, Greater Noida and Bhandwari; VAHAN; Green Delhi and SAMEER complaints; and brick-kiln biomass-fuel compliance in Haryana and Punjab.
- Working on 'Detect, Analyse, Act', it raises alerts and escalation when norms or statutory directions are breached; a State Action Plan module tracks pending actions in Delhi, Haryana, Punjab, Rajasthan and Uttar Pradesh.
- The Minister said agencies must act on alerts in real time, that non-compliant industries and congestion hotspots would be acted upon swiftly, and that construction and demolition across NCR would be halted from 5 to 20 November.
For Prelims
- CAQM: the Commission for Air Quality Management in National Capital Region and Adjoining Areas, a statutory body under the CAQM Act, 2021 (assent 12 August 2021), set up to coordinate, research and resolve air-quality problems in NCR; on air quality its directions take precedence over those of State authorities.
- GRAP: the Graded Response Action Plan, first notified in 2017, is implemented by CAQM; a revised GRAP has applied across NCR since 1 October 2023, with stage-wise curbs triggered using air-quality forecasts from IMD and IITM.
- CAAQMS: Continuous Ambient Air Quality Monitoring Stations - automatic stations run by CPCB, IMD and State Pollution Control Boards; PAVAN draws on 111 of them in Delhi-NCR.
- OCEMS: Online Continuous Emission Monitoring Systems on industrial stacks, reporting particulate matter, SO2, NOx and CO in real time - here fed directly into CAQM's alert system.
- FIRMS: NASA's Fire Information for Resource Management System, which maps active fires from satellite data; with ISRO and IARI data it is used to count crop-residue burning events in Punjab and Haryana.
- SAMEER and Green Delhi: SAMEER is CPCB's app for AQI information and pollution complaints; Green Delhi is the Delhi government's complaint app. Both feed citizen grievances into PAVAN.
- Construction and demolition dust: a recognised source of PM10 in NCR, which is why C&D curbs are a standard winter measure. The Minister announced a halt across NCR from 5 to 20 November.
- Earlier CAQM steps: web-camera monitoring of 2,013 registered construction sites in Haryana (carded 9 September, PRID 2308163) and PTZ cameras over industrial fuel stores (6 October, PRID 2319694). PAVAN brings such feeds onto one platform.
For UPSC: PAVAN-I3C = CAQM command centre for NCR air quality: 30+ data streams, 111 CAAQMS, 2,300+ industries, 3,200+ C&D sites; 'Detect, Analyse, Act'; NCR C&D halt 5-20 Nov.
What it is NOT: The release gives no cost, vendor or launch date, and no evidence yet of what the alerts have produced - no count of violations flagged, notices issued or units closed. It does not say whether the 5-20 November construction halt is a GRAP stage order or a separate direction, what exemptions apply, or what air quality levels prompted it. It also does not say whether PAVAN's data or alerts will be made public.

Anchor
Delhi's winter pollution has never lacked data; it has lacked enforcement that moves as fast as a smoke plume. CAQM's PAVAN centre is an attempt to close that gap.
Substantiation (data)
PAVAN-I3C integrates more than 30 data streams - 111 monitoring stations, 2,300 industries, 3,200 construction sites, satellite fire counts, landfills, VAHAN and citizen complaints - and turns deviations into alerts escalated to the responsible agency.
Position
Alert-based compliance is the right model for an airshed shared by five States. A single verified data source ends arguments over whose numbers are right and shortens the time between a violation and action on it.
Counterpoint
Dashboards do not enforce. The agencies receiving the alerts are the same under-staffed State boards and municipal bodies whose capacity has always been the constraint, and a construction halt remains a blunt emergency tool.
Way forward
Publish alert and action statistics by agency and State; open PAVAN's data to researchers and citizens; and use its record to move from emergency halts towards year-round, source-specific enforcement.
Conclusion
PAVAN can see the farm fire and the uncovered construction site. Whether the air improves depends on what happens after the alert.
