How much forest has Greater Noida lost?
There was almost no forest around Greater Noida 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.

Forest gained and lost, 2000–2020
- Forest in 2000
- 67 ha
- Forest in 2020
- 179 ha
- Overall change
- +112 hamore forest than in 2000
Comparing satellite maps from 2000 and 2020, the forest around Greater Noida grew from about 67 hectares to 179 hectares, a net gain of about 112 hectares. New forest grew on about 112 hectares, while under 1 hectare was lost.
These 2000 and 2020 maps, from the University of Maryland, count any land with trees taller than 5 m as forest, including plantations and orchards. Forest that was cut or burned and had grown back by 2020 counts in both years, so the loss here is smaller than the yearly figures.
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 Greater Noida
What is the air quality (AQI) in Greater Noida right now?
The latest reading for Greater Noida shows an AQI of 196 (Unhealthy), measured Nov 11, 21:45 local time by the Knowledge Park - III, Greater Noida - UPPCB ground monitoring station, 5.9 km away, via OpenAQ. The main pollutant is PM2.5. Everyone should limit long outdoor exertion; sensitive groups more so.
Is it safe to exercise outside in Greater Noida today?
At AQI 196 (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 Greater Noida been like this week?
Over the last 7 days, the CAMS air-quality model put Greater Noida's daily AQI at 202 on average, from 173 on Nov 9 to an hourly peak of 268 on Nov 4. On 7 of those days the average was above 100, unhealthy for sensitive groups.
Is Greater Noida'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 Greater Noida lost since 2001?
There was almost no forest around Greater Noida 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. Comparing satellite maps from 2000 and 2020, the forest around Greater Noida grew from about 67 hectares to 179 hectares, a net gain of about 112 hectares. New forest grew on about 112 hectares, while under 1 hectare was lost.
What is the tree count in Greater Noida?
Greater Noida has an estimated 57,491 trees across the 12.57 km² measured — 18.3% tree cover, 22 percentage points short of the 40% tree-cover target set for this area.
How many more trees does Greater Noida need?
Greater Noida needs roughly 68,173 more trees to close a 22-point shortfall against its 40% tree-cover target — about 1,500 t of extra CO₂ absorbed per year once grown.
How are Greater Noida's air quality and tree cover measured?
Air quality is measured by ground monitoring stations near Eta II, 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 Eta II; the tree count is an estimate derived from that cover.
