How much forest has Bokāro lost?
There was almost no forest around Bokāro 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 January 2017 of a 5 × 5 km area in the city center.
Forest gained and lost, 2000–2020
- Forest in 2000
- 1,840 ha
- Forest in 2020
- 2,240 ha
- Overall change
- +403 hamore forest than in 2000
Comparing satellite maps from 2000 and 2020, the forest around Bokāro grew from about 1,840 hectares to 2,240 hectares, a net gain of about 403 hectares (+22%). New forest grew on about 440 hectares, while 37 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 Bokāro
What is the air quality (AQI) in Bokāro right now?
The latest reading for Bokāro shows an AQI of 131 (Unhealthy for sensitive groups), observed Nov 11, 12:30 local time via Open-Meteo / CAMS, corrected with 3 ground-station cities within 85 km, US EPA index. The main pollutant is PM2.5. Sensitive groups should limit long or intense outdoor activity.
Is it safe to exercise outside in Bokāro today?
At AQI 131 (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 Bokāro been like this week?
Over the last 7 days, the CAMS air-quality model put Bokāro's daily AQI at 178 on average, from 156 on Nov 9 to an hourly peak of 211 on Nov 10. On 7 of those days the average was above 100, unhealthy for sensitive groups.
Is Bokāro'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 Bokāro lost since 2001?
There was almost no forest around Bokāro 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 Bokāro grew from about 1,840 hectares to 2,240 hectares, a net gain of about 403 hectares (+22%). New forest grew on about 440 hectares, while 37 hectares were lost.
What is the tree count in Bokāro?
Bokāro has an estimated 193,248 trees across the 11.84 km² of land measured — 65.3% tree cover, already past the 35% tree-cover target set for this area.
How many more trees does Bokāro need?
Bokāro has already reached its tree-cover target, so no additional trees are needed to close the gap.
How are Bokāro'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 Sector 4; the tree count is an estimate derived from that cover.
