How much forest has Sītāpur lost?
There was very little forest around Sītāpur in 2000, about 99 hectares, and about 15 hectares 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.

The worst year was 2012, when about 3 hectares of forest were lost.

Comparing satellite maps from 2000 and 2020, the forest around Sītāpur grew from about 1,670 hectares to 2,100 hectares, a net gain of about 432 hectares (+26%). New forest grew on about 467 hectares, while 35 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.

Questions about Sītāpur
What is the air quality (AQI) in Sītāpur right now?
The latest reading for Sītāpur shows an AQI of 168 (Unhealthy), observed Nov 11, 03:30 local time via Open-Meteo / CAMS, corrected with 7 ground-station cities within 165 km, US EPA index. The main pollutant is PM2.5. Everyone should limit long outdoor exertion; sensitive groups more so.
Is it safe to exercise outside in Sītāpur today?
At AQI 168 (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 Sītāpur been like this week?
Over the last 7 days, the CAMS air-quality model put Sītāpur's daily AQI at 174 on average, from 111 on Nov 10 to an hourly peak of 261 on Nov 8. On 7 of those days the average was above 100, unhealthy for sensitive groups.
Is Sītāpur'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 Sītāpur lost since 2001?
There was very little forest around Sītāpur in 2000, about 99 hectares, and about 15 hectares 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. Comparing satellite maps from 2000 and 2020, the forest around Sītāpur grew from about 1,670 hectares to 2,100 hectares, a net gain of about 432 hectares (+26%). New forest grew on about 467 hectares, while 35 hectares were lost.
What is the tree count in Sītāpur?
Sītāpur has an estimated 129,119 trees across the 12.57 km² measured — 41.1% tree cover, already past the 40% tree-cover target set for this area.
How many more trees does Sītāpur need?
Sītāpur has already reached its tree-cover target, so no additional trees are needed to close the gap.
How are Sītāpur'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 Arya Nagar; the tree count is an estimate derived from that cover.
