How much forest has Bhāgalpur lost?
There was almost no forest around Bhāgalpur 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
- 967 ha
- Forest in 2020
- 1,110 ha
- Overall change
- +147 hamore forest than in 2000
Comparing satellite maps from 2000 and 2020, the forest around Bhāgalpur grew from about 967 hectares to 1,110 hectares, a net gain of about 147 hectares (+15%). New forest grew on about 147 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 Bhāgalpur
What is the air quality (AQI) in Bhāgalpur right now?
The latest reading for Bhāgalpur shows an AQI of 160 (Unhealthy), measured Nov 11, 21:30 local time by 2 ground monitoring stations via OpenAQ (the median of their readings; the nearest is Mayaganj, Bhagalpur - BSPCB, 4.7 km away). The main pollutant is PM2.5. Everyone should limit long outdoor exertion; sensitive groups more so.
Is it safe to exercise outside in Bhāgalpur today?
At AQI 160 (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 Bhāgalpur been like this week?
Over the last 7 days, the CAMS air-quality model put Bhāgalpur's daily AQI at 169 on average, from 128 on Nov 9 to an hourly peak of 219 on Nov 8. On 7 of those days the average was above 100, unhealthy for sensitive groups.
Is Bhāgalpur'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 Bhāgalpur lost since 2001?
There was almost no forest around Bhāgalpur 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 Bhāgalpur grew from about 967 hectares to 1,110 hectares, a net gain of about 147 hectares (+15%).

What is the tree count in Bhāgalpur?
Bhāgalpur has an estimated 65,839 trees across the 10.89 km² of land measured — 24.2% tree cover, 16 percentage points short of the 40% tree-cover target set for this area.
How many more trees does Bhāgalpur need?
Bhāgalpur needs roughly 42,986 more trees to close a 16-point shortfall against its 40% tree-cover target — about 945.7 t of extra CO₂ absorbed per year once grown.
How are Bhāgalpur's air quality and tree cover measured?
Air quality is measured by ground monitoring stations near Laheari Tola, 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 Laheari Tola; the tree count is an estimate derived from that cover.
