How much forest has Prayagraj lost?
There was almost no forest around Prayagraj 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
- 242 ha
- Forest in 2020
- 290 ha
- Overall change
- +48 hamore forest than in 2000
Comparing satellite maps from 2000 and 2020, the forest around Prayagraj grew from about 242 hectares to 290 hectares, a net gain of about 48 hectares (+20%). New forest grew on about 55 hectares, while 8 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 Prayagraj
What is the air quality (AQI) in Prayagraj right now?
The latest reading for Prayagraj shows an AQI of 215 (Very unhealthy), observed Nov 11, 06:30 local time via Open-Meteo / CAMS, corrected with 4 ground-station cities within 145 km, US EPA index. The main pollutant is PM2.5. Health alert — everyone should avoid long outdoor exertion.
Is it safe to exercise outside in Prayagraj today?
At AQI 215 (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 Prayagraj been like this week?
Over the last 7 days, the CAMS air-quality model put Prayagraj's daily AQI at 200 on average, from 191 on Nov 8 to an hourly peak of 261 on Nov 7. On 7 of those days the average was above 100, unhealthy for sensitive groups.
Is Prayagraj'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 Prayagraj lost since 2001?
There was almost no forest around Prayagraj 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 Prayagraj grew from about 242 hectares to 290 hectares, a net gain of about 48 hectares (+20%). New forest grew on about 55 hectares, while 8 hectares were lost.
What is the tree count in Prayagraj?
Prayagraj has an estimated 80,739 trees across the 12.57 km² measured — 25.7% tree cover, 19 percentage points short of the 45% tree-cover target set for this area.
How many more trees does Prayagraj need?
Prayagraj needs roughly 60,633 more trees to close a 19-point shortfall against its 45% tree-cover target — about 1,334 t of extra CO₂ absorbed per year once grown.
How are Prayagraj's air quality and tree cover measured?
Air quality comes from ground monitoring stations via OpenAQ where one reports nearby, and otherwise, as here, from the Open-Meteo / CAMS model, which may differ from street-level monitors. 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 North Malaka; the tree count is an estimate derived from that cover.
