How much forest has Sambhal lost?
There was very little forest around Sambhal in 2000, about 6 hectares, and about 3 hectares of it has been lost since. Only fairly dense woodland counts as forest in these maps, so scattered street and garden trees don't show up here.

The worst year was 2006, when about 2 hectares of forest were lost.

Causes for 2025 are estimates, based on what caused forest loss in the same places up to 2024.
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 Sambhal
What is the air quality (AQI) in Sambhal right now?
The latest reading for Sambhal shows an AQI of 158 (Unhealthy), observed Nov 10, 20:30 local time via Open-Meteo / CAMS, corrected with 19 ground-station cities within 145 km, US EPA index. The main pollutant is PM2.5. Everyone should limit long outdoor exertion; sensitive groups more so.
Is it safe to exercise outside in Sambhal today?
At AQI 158 (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 Sambhal been like this week?
Over the last 7 days, the CAMS air-quality model put Sambhal's daily AQI at 185 on average, from 145 on Nov 10 to an hourly peak of 252 on Nov 8. On 7 of those days the average was above 100, unhealthy for sensitive groups.
Is Sambhal'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 Sambhal lost since 2001?
There was very little forest around Sambhal in 2000, about 6 hectares, and about 3 hectares of it has been lost since. Only fairly dense woodland counts as forest in these maps, so scattered street and garden trees don't show up here.
What is the tree count in Sambhal?
Sambhal has an estimated 46,622 trees across the 12.52 km² of land measured — 14.9% tree cover, 25 percentage points short of the 40% tree-cover target set for this area.
How many more trees does Sambhal need?
Sambhal needs roughly 78,539 more trees to close a 25-point shortfall against its 40% tree-cover target — about 1,728 t of extra CO₂ absorbed per year once grown.
How are Sambhal'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 Sambhal; the tree count is an estimate derived from that cover.
