How much forest has Ballari lost?
There was almost no forest around Ballari 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
- 192 ha
- Forest in 2020
- 293 ha
- Overall change
- +101 hamore forest than in 2000
Comparing satellite maps from 2000 and 2020, the forest around Ballari grew from about 192 hectares to 293 hectares, a net gain of about 101 hectares (+53%). New forest grew on about 101 hectares, while under 1 hectare was 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 Ballari
What is the air quality (AQI) in Ballari right now?
The latest reading for Ballari shows an AQI of 78 (Moderate), observed Nov 11, 15:30 local time via Open-Meteo / CAMS, corrected with 3 ground-station cities within 185 km, US EPA index. The main pollutant is PM2.5. Unusually sensitive people should consider limiting long outdoor exertion.
Is it safe to exercise outside in Ballari today?
At AQI 78 (Moderate): fine for most people; unusually sensitive people should take long or hard exercise easier. Windows: fine to open; close them if you are sensitive to pollution. Masks: not needed for most people. The reading changes through the day, so check again before a long run or ride.
What has the air quality in Ballari been like this week?
Over the last 7 days, the CAMS air-quality model put Ballari's daily AQI at 73 on average, from 34 on Nov 6 to an hourly peak of 135 on Nov 10. On 1 of those days the average was above 100, unhealthy for sensitive groups.
Is Ballari'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 Ballari lost since 2001?
There was almost no forest around Ballari 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 Ballari grew from about 192 hectares to 293 hectares, a net gain of about 101 hectares (+53%). New forest grew on about 101 hectares, while under 1 hectare was lost.
What is the tree count in Ballari?
Ballari has an estimated 75,247 trees across the 12.54 km² of land measured — 24.0% tree cover, 6 percentage points short of the 30% tree-cover target set for this area.
How many more trees does Ballari need?
Ballari needs roughly 18,812 more trees to close a 6-point shortfall against its 30% tree-cover target — about 413.9 t of extra CO₂ absorbed per year once grown.
How are Ballari'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 BSNL Colony; the tree count is an estimate derived from that cover.
