How much forest has Chittoor lost?
There was very little forest around Chittoor in 2000, about 85 hectares, and about 4 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.
2017: satellite photo from February 2017 of a 5 × 5 km area in the city center.
The worst year was 2001, when about 1 hectare of forest were lost.

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

- Overall change
- +835 hamore forest than in 2000
Comparing satellite maps from 2000 and 2020, the forest around Chittoor grew from about 5,290 hectares to 6,120 hectares, a net gain of about 835 hectares (+16%). New forest grew on about 860 hectares, while 25 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 Chittoor
What is the air quality (AQI) in Chittoor right now?
The latest reading for Chittoor shows an AQI of 114 (Unhealthy for sensitive groups), measured Nov 11, 20:45 local time by the Gangineni Cheruvu, Chittoor - APPCB ground monitoring station, 700 m away, via OpenAQ. The main pollutant is PM2.5. Sensitive groups should limit long or intense outdoor activity.
Is it safe to exercise outside in Chittoor today?
At AQI 114 (Unhealthy for sensitive groups): children, older adults and people with asthma or heart disease should cut down long or hard exercise. Windows: close them to keep the outside air out. Masks: sensitive groups: an N95 outdoors. The reading changes through the day, so check again before a long run or ride.
What has the air quality in Chittoor been like this week?
Over the last 7 days, the CAMS air-quality model put Chittoor's daily AQI at 89 on average, from 43 on Nov 6 to an hourly peak of 147 on Nov 9. On 3 of those days the average was above 100, unhealthy for sensitive groups.
Is Chittoor'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 Chittoor lost since 2001?
There was very little forest around Chittoor in 2000, about 85 hectares, and about 4 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 Chittoor grew from about 5,290 hectares to 6,120 hectares, a net gain of about 835 hectares (+16%). New forest grew on about 860 hectares, while 25 hectares were lost.
What is the tree count in Chittoor?
Chittoor has an estimated 129,119 trees across the 12.57 km² measured — 41.1% tree cover, already past the 35% tree-cover target set for this area.
How many more trees does Chittoor need?
Chittoor has already reached its tree-cover target, so no additional trees are needed to close the gap.
How are Chittoor's air quality and tree cover measured?
Air quality is measured by ground monitoring stations near Kondamitta, 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 Kondamitta; the tree count is an estimate derived from that cover.
