Forest gained and lost, 2000–2020
- Forest in 2000
- 9,930 ha
- Forest in 2020
- 10,400 ha
- Overall change
- +453 hamore forest than in 2000
Comparing satellite maps from 2000 and 2020, the forest around Basirhat City grew from about 9,930 hectares to 10,400 hectares, a net gain of about 453 hectares (+4.6%). New forest grew on about 461 hectares, while 9 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.

Questions about Basirhat City
What is the air quality (AQI) in Basirhat City right now?
The latest reading for Basirhat City shows an AQI of 83 (Moderate), observed Nov 11, 03:30 local time via Open-Meteo / CAMS, corrected with 22 ground-station cities within 225 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 Basirhat City today?
At AQI 83 (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 Basirhat City been like this week?
Over the last 7 days, the CAMS air-quality model put Basirhat City's daily AQI at 155 on average, from 104 on Nov 10 to an hourly peak of 204 on Nov 8. On 7 of those days the average was above 100, unhealthy for sensitive groups.
Is Basirhat City'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 Basirhat City lost since 2001?
Almost no forest has been lost around Basirhat City since 2001: less than 1 hectare of the 401 hectares there in 2000. Comparing satellite maps from 2000 and 2020, the forest around Basirhat City grew from about 9,930 hectares to 10,400 hectares, a net gain of about 453 hectares (+4.6%). New forest grew on about 461 hectares, while 9 hectares were lost.
What is the tree count in Basirhat City?
Basirhat City has an estimated 203,569 trees across the 11.38 km² of land measured — 71.6% tree cover, already past the 30% tree-cover target set for this area.
How many more trees does Basirhat City need?
Basirhat City has already reached its tree-cover target, so no additional trees are needed to close the gap.
How are Basirhat City'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 Basirhat; the tree count is an estimate derived from that cover.
