How much forest has Rewāri lost?

Comparing satellite maps from 2000 and 2020, the forest around Rewāri grew from about 54 hectares to 137 hectares, a net gain of about 83 hectares. New forest grew on about 83 hectares, while under 1 hectare was 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 Rewāri
What is the air quality (AQI) in Rewāri right now?
The latest reading for Rewāri shows an AQI of 390 (Hazardous), measured Nov 11, 19:45 local time by 3 ground monitoring stations via OpenAQ (the median of their readings; the nearest is Municipal Corporation Office, Dharuhera - HSPCB, 17.8 km away). The main pollutant is PM10. Emergency conditions — avoid outdoor activity.
Is it safe to exercise outside in Rewāri today?
At AQI 390 (Hazardous): everyone should avoid all outdoor exertion. Windows: keep them closed and seal gaps. Masks: wear an N95 if you must go out. The reading changes through the day, so check again before a long run or ride.
What has the air quality in Rewāri been like this week?
Over the last 7 days, the CAMS air-quality model put Rewāri's daily AQI at 196 on average, from 168 on Nov 7 to an hourly peak of 259 on Nov 5. On 7 of those days the average was above 100, unhealthy for sensitive groups.
Is Rewāri'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 Rewāri lost since 2001?
There was very little forest around Rewāri in 2000, about 12 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 Rewāri grew from about 54 hectares to 137 hectares, a net gain of about 83 hectares. New forest grew on about 83 hectares, while under 1 hectare was lost.
What is the tree count in Rewāri?
Rewāri has an estimated 58,061 trees across the 12.56 km² of land measured — 18.5% tree cover, 27 percentage points short of the 45% tree-cover target set for this area.
How many more trees does Rewāri need?
Rewāri needs roughly 83,169 more trees to close a 27-point shortfall against its 45% tree-cover target — about 1,830 t of extra CO₂ absorbed per year once grown.
How are Rewāri's air quality and tree cover measured?
Air quality is measured by ground monitoring stations near Mohalla Madai, 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 Mohalla Madai; the tree count is an estimate derived from that cover.
