Comparing satellite maps from 2000 and 2020, the forest around Rānipet grew from about 2,270 hectares to 2,560 hectares, a net gain of about 288 hectares (+13%). New forest grew on about 319 hectares, while 31 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 Rānipet
What is the air quality (AQI) in Rānipet right now?
The latest reading for Rānipet shows an AQI of 154 (Unhealthy), observed Nov 10, 19:30 local time via Open-Meteo / CAMS, corrected with 5 ground-station cities within 105 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 Rānipet today?
At AQI 154 (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 Rānipet been like this week?
Over the last 7 days, the CAMS air-quality model put Rānipet's daily AQI at 87 on average, from 54 on Nov 6 to an hourly peak of 143 on Nov 9. On 2 of those days the average was above 100, unhealthy for sensitive groups.
Is Rānipet'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 Rānipet lost since 2001?
Since 2001, the area within 10 km of Rānipet has lost about 63 hectares of forest (about 88 football pitches): 45% of the forest it had in 2000. Most of it (85%) was deforestation, forest cleared for good, mainly for farms, pasture and plantations. Comparing satellite maps from 2000 and 2020, the forest around Rānipet grew from about 2,270 hectares to 2,560 hectares, a net gain of about 288 hectares (+13%). New forest grew on about 319 hectares, while 31 hectares were lost.
What is the tree count in Rānipet?
Rānipet has an estimated 120,951 trees across the 12.57 km² measured — 38.5% tree cover, 2 percentage points short of the 40% tree-cover target set for this area.
How many more trees does Rānipet need?
Rānipet needs roughly 4,712 more trees to close a 2-point shortfall against its 40% tree-cover target — about 103.7 t of extra CO₂ absorbed per year once grown.
How are Rānipet'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 Ranipet; the tree count is an estimate derived from that cover.
