How much forest has Bihār Sharīf lost?
There was almost no forest around Bihār Sharīf 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
- 241 ha
- Forest in 2020
- 318 ha
- Overall change
- +77 hamore forest than in 2000
Comparing satellite maps from 2000 and 2020, the forest around Bihār Sharīf grew from about 241 hectares to 318 hectares, a net gain of about 77 hectares (+32%). New forest grew on about 77 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.

At AQI 208 (Very unhealthy): everyone should avoid long or hard exercise outdoors; sensitive groups, all outdoor exertion. Windows: keep them closed. Masks: wear an N95 if you go out. The reading changes through the day, so check again before a long run or ride.
What has the air quality in Bihār Sharīf been like this week?
Over the last 7 days, the CAMS air-quality model put Bihār Sharīf's daily AQI at 188 on average, from 160 on Nov 9 to an hourly peak of 234 on Nov 8. On 7 of those days the average was above 100, unhealthy for sensitive groups.
Is Bihār Sharīf'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 Bihār Sharīf lost since 2001?
