How much forest has Korba lost?
There was very little forest around Korba in 2000, about 31 hectares, and about 2 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.

Causes for 2025 are estimates, based on what caused forest loss in the same places up to 2024.

- Forest in 2000
- 1,690 ha
- Forest in 2020

- Overall change
- +692 hamore forest than in 2000
Comparing satellite maps from 2000 and 2020, the forest around Korba grew from about 1,690 hectares to 2,380 hectares, a net gain of about 692 hectares (+41%). New forest grew on about 719 hectares, while 27 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 Korba
What is the air quality (AQI) in Korba right now?
The latest reading for Korba shows an AQI of 87 (Moderate), measured Nov 11, 20:45 local time by the Rampur, Korba - CECB ground monitoring station, 5.7 km away, via OpenAQ. The main pollutant is PM2.5. Unusually sensitive people should consider limiting long outdoor exertion.
Is it safe to exercise outside in Korba today?
At AQI 87 (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 Korba been like this week?
Over the last 7 days, the CAMS air-quality model put Korba's daily AQI at 163 on average, from 149 on Nov 9 to an hourly peak of 183 on Nov 10. On 7 of those days the average was above 100, unhealthy for sensitive groups.
Is Korba'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 Korba lost since 2001?
There was very little forest around Korba in 2000, about 31 hectares, and about 2 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. Comparing satellite maps from 2000 and 2020, the forest around Korba grew from about 1,690 hectares to 2,380 hectares, a net gain of about 692 hectares (+41%). New forest grew on about 719 hectares, while 27 hectares were lost.
What is the tree count in Korba?
Korba has an estimated 95,907 trees across the 12.03 km² of land measured — 31.9% tree cover, already past the 30% tree-cover target set for this area.
How many more trees does Korba need?
Korba has already reached its tree-cover target, so no additional trees are needed to close the gap.
How are Korba's air quality and tree cover measured?
Air quality is measured by ground monitoring stations near Mohanpur, 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 Mohanpur; the tree count is an estimate derived from that cover.
