How much forest has Neyveli lost?
There was almost no forest around Neyveli 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
- 8,700 ha
- Forest in 2020
- 8,850 ha
- Overall change
- +154 hamore forest than in 2000
Comparing satellite maps from 2000 and 2020, the forest around Neyveli stayed about the same size, at about 8,850 hectares: new forest grew on about 428 hectares, and about 274 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 Neyveli
What is the air quality (AQI) in Neyveli right now?
The latest reading for Neyveli shows an AQI of 155 (Unhealthy), observed Nov 11, 02:30 local time via Open-Meteo / CAMS, corrected with 6 ground-station cities within 185 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 Neyveli today?
At AQI 155 (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 Neyveli been like this week?
Over the last 7 days, the CAMS air-quality model put Neyveli's daily AQI at 80 on average, from 40 on Nov 7 to an hourly peak of 133 on Nov 10. On 3 of those days the average was above 100, unhealthy for sensitive groups.
Is Neyveli'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 Neyveli lost since 2001?
There was almost no forest around Neyveli 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 Neyveli stayed about the same size, at about 8,850 hectares: new forest grew on about 428 hectares, and about 274 hectares were lost.
What is the tree count in Neyveli?
Neyveli has an estimated 220,540 trees across the 12.57 km² measured — 70.2% tree cover, already past the 40% tree-cover target set for this area.
How many more trees does Neyveli need?
Neyveli has already reached its tree-cover target, so no additional trees are needed to close the gap.
How are Neyveli'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 Neyveli Twp Block-17; the tree count is an estimate derived from that cover.
