How much forest has Rewa lost?
There was almost no forest around Rewa 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
- 402 ha
- Forest in 2020
- 465 ha
- Overall change
- +63 hamore forest than in 2000
Comparing satellite maps from 2000 and 2020, the forest around Rewa grew from about 402 hectares to 465 hectares, a net gain of about 63 hectares (+16%). New forest grew on about 65 hectares, while 2 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 Rewa
What is the air quality (AQI) in Rewa right now?
The latest reading for Rewa shows an AQI of 162 (Unhealthy), observed Nov 10, 20:30 local time via Open-Meteo / CAMS, corrected with 6 ground-station cities within 205 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 Rewa today?
At AQI 162 (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 Rewa been like this week?
Over the last 7 days, the CAMS air-quality model put Rewa's daily AQI at 160 on average, from 155 on Nov 6 to an hourly peak of 182 on Nov 10. On 7 of those days the average was above 100, unhealthy for sensitive groups.
Is Rewa'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 Rewa lost since 2001?
There was almost no forest around Rewa 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 Rewa grew from about 402 hectares to 465 hectares, a net gain of about 63 hectares (+16%). New forest grew on about 65 hectares, while 2 hectares were lost.
What is the tree count in Rewa?
Rewa has an estimated 108,196 trees across the 12.37 km² of land measured — 35.0% tree cover, 5 percentage points short of the 40% tree-cover target set for this area.
How many more trees does Rewa need?
Rewa needs roughly 15,457 more trees to close a 5-point shortfall against its 40% tree-cover target — about 340.1 t of extra CO₂ absorbed per year once grown.
How are Rewa'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 Tarahti; the tree count is an estimate derived from that cover.
