Causes for 2025 are estimates, based on what caused forest loss in the same places up to 2024.

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.

Frequently asked

Questions about Narela

What is the air quality (AQI) in Narela right now?

The latest reading for Narela shows an AQI of 198 (Unhealthy), measured Nov 11, 21:00 local time by 3 ground monitoring stations via OpenAQ (the median of their readings; the nearest is Narela, Delhi - DPCC, 3.4 km away). The main pollutant is PM2.5. Everyone should limit long outdoor exertion; sensitive groups more so.

Is it safe to exercise outside in Narela today?

At AQI 198 (Unhealthy): everyone should cut down long or hard exercise; sensitive groups should avoid it. Windows: keep them closed. Masks: wear an N95 outdoors. The reading changes through the day, so check again before a long run or ride.

What has the air quality in Narela been like this week?

Over the last 7 days, the CAMS air-quality model put Narela's daily AQI at 200 on average, from 173 on Nov 7 to an hourly peak of 257 on Nov 4. On 7 of those days the average was above 100, unhealthy for sensitive groups.

Is Narela'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 Narela lost since 2001?

There was very little forest around Narela in 2000, about 8 hectares, and about 1 hectare of it has been lost since. Only fairly dense woodland counts as forest in these maps, so scattered street and garden trees don't show up here.

What is the tree count in Narela?

Narela has an estimated 56,863 trees across the 12.57 km² measured — 18.1% tree cover, 22 percentage points short of the 40% tree-cover target set for this area.

How many more trees does Narela need?

Narela needs roughly 68,801 more trees to close a 22-point shortfall against its 40% tree-cover target — about 1,514 t of extra CO₂ absorbed per year once grown.

How are Narela's air quality and tree cover measured?

Air quality is measured by ground monitoring stations near Pana Paposia, 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 Pana Paposia; the tree count is an estimate derived from that cover.
