These figures cover everything within 10 km of the city center, a wider area than the report above, because forest is usually lost at a city's edges.

The latest reading for Najafgarh shows an AQI of 219 (Very unhealthy), measured Nov 11, 20:00 local time by 4 ground monitoring stations via OpenAQ (the median of their readings; the nearest is NSIT Dwarka, Delhi - CPCB, 5.1 km away). The main pollutant is PM2.5. Health alert — everyone should avoid long outdoor exertion.
Is it safe to exercise outside in Najafgarh today?
At AQI 219 (Very unhealthy): everyone should avoid long or hard exercise outdoors; sensitive groups, all outdoor exertion. Windows: keep them closed. Masks: wear an N95 if you go out. The reading changes through the day, so check again before a long run or ride.
What has the air quality in Najafgarh been like this week?
Over the last 7 days, the CAMS air-quality model put Najafgarh's daily AQI at 202 on average, from 170 on Nov 7 to an hourly peak of 265 on Nov 5. On 7 of those days the average was above 100, unhealthy for sensitive groups.
Is Najafgarh's AQI the same as India's AQI (CPCB)?
No. Airleaf shows the US EPA Air Quality Index (AQI), the scale used by IQAir and most air-quality apps. India's Central Pollution Control Board (CPCB) publishes the National Air Quality Index on its own scale: 0–50 good, 51–100 satisfactory, 101–200 moderate, 201–300 poor, 301–400 very poor and 401–500 severe. The two scales don't line up. At moderate fine-particle levels the US scale reads higher: 55 µg/m³ of PM2.5 is 149 on the US AQI but about 92, "satisfactory", on India's. In heavy smog India's reads higher: 100 µg/m³ is 182 on the US AQI and about 232, "poor", on India's. CPCB also averages particles over 24 hours, so its figure moves more slowly than an hourly reading.
How much forest has the area around Najafgarh lost since 2001?
There was almost no forest around Najafgarh in 2000, so there has been almost nothing to lose since. Only fairly dense woodland counts as forest in these maps, so scattered street and garden trees don't show up here.

How many more trees does Najafgarh need?
Najafgarh needs roughly 111,841 more trees to close a 36-point shortfall against its 45% tree-cover target — about 2,461 t of extra CO₂ absorbed per year once grown.
How are Najafgarh's air quality and tree cover measured?
Air quality is measured by ground monitoring stations near Prem Nagar, via OpenAQ; the 7-day trend is the Open-Meteo / CAMS model's estimate. Tree cover is measured from Sentinel-2 L2A (ESA Copernicus) via Earth Search satellite imagery at 10 m detail across a 2 km radius around Prem Nagar; the tree count is an estimate derived from that cover.
