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

- +267 hamore forest than in 2000
Comparing satellite maps from 2000 and 2020, the forest around Deoli grew from about 401 hectares to 668 hectares, a net gain of about 267 hectares (+67%). New forest grew on about 272 hectares, while 6 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 Deoli
What is the air quality (AQI) in Deoli right now?
The latest reading for Deoli shows an AQI of 235 (Very unhealthy), measured Nov 11, 22:00 local time by 9 ground monitoring stations via OpenAQ (the median of their readings; the nearest is Dr. Karni Singh Shooting Range, Delhi - DPCC, 3.3 km away). The main pollutant is PM2.5. Health alert — everyone should avoid long outdoor exertion.
Is it safe to exercise outside in Deoli today?
At AQI 235 (Very unhealthy): everyone should avoid long or hard exercise outdoors; sensitive groups, all outdoor exertion. Windows: keep them closed. Masks: wear an N95 if you go out. The reading changes through the day, so check again before a long run or ride.
What has the air quality in Deoli been like this week?
Over the last 7 days, the CAMS air-quality model put Deoli's daily AQI at 213 on average, from 186 on Nov 7 to an hourly peak of 280 on Nov 5. On 7 of those days the average was above 100, unhealthy for sensitive groups.
Is Deoli'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 Deoli lost since 2001?
There was very little forest around Deoli in 2000, about 85 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. Comparing satellite maps from 2000 and 2020, the forest around Deoli grew from about 401 hectares to 668 hectares, a net gain of about 267 hectares (+67%). New forest grew on about 272 hectares, while 6 hectares were lost.
What is the tree count in Deoli?
Deoli has an estimated 114,668 trees across the 12.57 km² measured — 36.5% tree cover, 9 percentage points short of the 45% tree-cover target set for this area.
How many more trees does Deoli need?
Deoli needs roughly 26,704 more trees to close a 9-point shortfall against its 45% tree-cover target — about 587.5 t of extra CO₂ absorbed per year once grown.
How are Deoli's air quality and tree cover measured?
Air quality is measured by ground monitoring stations near Deoli, 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 Deoli; the tree count is an estimate derived from that cover.
