How much forest has Ranchi lost?
There was almost no forest around Ranchi 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.
2017: satellite photo from March 2017 of a 5 × 5 km area in the city center.
Forest gained and lost, 2000–2020
- Forest in 2000
- 1,860 ha
- Forest in 2020
- 2,130 ha
- Overall change
- +270 hamore forest than in 2000
Comparing satellite maps from 2000 and 2020, the forest around Ranchi grew from about 1,860 hectares to 2,130 hectares, a net gain of about 270 hectares (+15%). New forest grew on about 281 hectares, while 10 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 Ranchi
What is the air quality (AQI) in Ranchi right now?
The latest reading for Ranchi shows an AQI of 98 (Moderate), observed Nov 11, 12:30 local time via Open-Meteo / CAMS, corrected with 2 ground-station cities within 145 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 Ranchi today?
At AQI 98 (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 Ranchi been like this week?
Over the last 7 days, the CAMS air-quality model put Ranchi's daily AQI at 152 on average, from 130 on Nov 9 to an hourly peak of 178 on Nov 8. On 7 of those days the average was above 100, unhealthy for sensitive groups.
Is Ranchi'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 Ranchi lost since 2001?
There was almost no forest around Ranchi 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 Ranchi grew from about 1,860 hectares to 2,130 hectares, a net gain of about 270 hectares (+15%). New forest grew on about 281 hectares, while 10 hectares were lost.
What is the tree count in Ranchi?
Ranchi has an estimated 116,867 trees across the 12.57 km² measured — 37.2% tree cover, already past the 30% tree-cover target set for this area.
How many more trees does Ranchi need?
Ranchi has already reached its tree-cover target, so no additional trees are needed to close the gap.
How are Ranchi'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 Vodyanagar; the tree count is an estimate derived from that cover.
