How much forest has Begusarai lost?
There was almost no forest around Begusarai 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
- 1,620 ha
- Forest in 2020
- 1,750 ha
- Overall change
- +138 hamore forest than in 2000
Comparing satellite maps from 2000 and 2020, the forest around Begusarai grew from about 1,620 hectares to 1,750 hectares, a net gain of about 138 hectares (+8.5%). New forest grew on about 150 hectares, while 12 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 Begusarai
What is the air quality (AQI) in Begusarai right now?
The latest reading for Begusarai shows an AQI of 163 (Unhealthy), measured Nov 11, 20:30 local time by the DRCC Anandpur, Begusarai - BSPCB ground monitoring station, 2.9 km away, via OpenAQ. The main pollutant is PM2.5. Everyone should limit long outdoor exertion; sensitive groups more so.
Is it safe to exercise outside in Begusarai today?
At AQI 163 (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 Begusarai been like this week?
Over the last 7 days, the CAMS air-quality model put Begusarai's daily AQI at 180 on average, from 140 on Nov 9 to an hourly peak of 236 on Nov 8. On 7 of those days the average was above 100, unhealthy for sensitive groups.
Is Begusarai'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 Begusarai lost since 2001?
There was almost no forest around Begusarai 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 Begusarai grew from about 1,620 hectares to 1,750 hectares, a net gain of about 138 hectares (+8.5%). New forest grew on about 150 hectares, while 12 hectares were lost.
What is the tree count in Begusarai?
Begusarai has an estimated 95,556 trees across the 12.49 km² of land measured — 30.6% tree cover, 9 percentage points short of the 40% tree-cover target set for this area.
How many more trees does Begusarai need?
Begusarai needs roughly 29,354 more trees to close a 9-point shortfall against its 40% tree-cover target — about 645.8 t of extra CO₂ absorbed per year once grown.
How are Begusarai's air quality and tree cover measured?
Air quality is measured by ground monitoring stations near Sarvodaya Nagar, 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 Sarvodaya Nagar; the tree count is an estimate derived from that cover.
