How much forest has Ghāziābād lost?
There was almost no forest around Ghāziābād 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
- 126 ha
- Forest in 2020
- 202 ha
- Overall change
- +76 hamore forest than in 2000
Comparing satellite maps from 2000 and 2020, the forest around Ghāziābād grew from about 126 hectares to 202 hectares, a net gain of about 76 hectares (+60%). New forest grew on about 80 hectares, while 4 hectares were 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 Ghāziābād
What is the air quality (AQI) in Ghāziābād right now?
The latest reading for Ghāziābād shows an AQI of 202 (Very unhealthy), measured Nov 11, 20:00 local time by 4 ground monitoring stations via OpenAQ (the median of their readings; the nearest is Sanjay Nagar, Ghaziabad - UPPCB, 2.6 km away). The main pollutant is PM2.5. Health alert — everyone should avoid long outdoor exertion.
Is it safe to exercise outside in Ghāziābād today?
At AQI 202 (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 Ghāziābād been like this week?
Over the last 7 days, the CAMS air-quality model put Ghāziābād's daily AQI at 189 on average, from 169 on Nov 7 to an hourly peak of 251 on Nov 4. On 7 of those days the average was above 100, unhealthy for sensitive groups.
Is Ghāziābād'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 Ghāziābād lost since 2001?
There was almost no forest around Ghāziābād 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 Ghāziābād grew from about 126 hectares to 202 hectares, a net gain of about 76 hectares (+60%). New forest grew on about 80 hectares, while 4 hectares were lost.
What is the tree count in Ghāziābād?
Ghāziābād has an estimated 54,978 trees across the 12.57 km² measured — 17.5% tree cover, 28 percentage points short of the 45% tree-cover target set for this area.
How many more trees does Ghāziābād need?
Ghāziābād needs roughly 86,394 more trees to close a 28-point shortfall against its 45% tree-cover target — about 1,901 t of extra CO₂ absorbed per year once grown.
How are Ghāziābād's air quality and tree cover measured?
Air quality is measured by ground monitoring stations near Pocket C, 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 Pocket C; the tree count is an estimate derived from that cover.
