How much forest has Deoria lost?
There was very little forest around Deoria in 2000, about 80 hectares, and about 13 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.
2017: satellite photo from February 2017 of a 5 × 5 km area in the city center.
The worst year was 2005, when about 3 hectares of forest were lost.

Comparing satellite maps from 2000 and 2020, the forest around Deoria grew from about 608 hectares to 690 hectares, a net gain of about 82 hectares (+13%). New forest grew on about 100 hectares, while 17 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 Deoria
What is the air quality (AQI) in Deoria right now?
The latest reading for Deoria shows an AQI of 193 (Unhealthy), observed Nov 11, 03:30 local time via Open-Meteo / CAMS, corrected with 20 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 Deoria today?
At AQI 193 (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 Deoria been like this week?
Over the last 7 days, the CAMS air-quality model put Deoria's daily AQI at 206 on average, from 174 on Nov 9 to an hourly peak of 298 on Nov 8. On 7 of those days the average was above 100, unhealthy for sensitive groups.
Is Deoria'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 Deoria lost since 2001?
There was very little forest around Deoria in 2000, about 80 hectares, and about 13 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 Deoria grew from about 608 hectares to 690 hectares, a net gain of about 82 hectares (+13%). New forest grew on about 100 hectares, while 17 hectares were lost.
What is the tree count in Deoria?
Deoria has an estimated 74,770 trees across the 12.57 km² measured — 23.8% tree cover, 16 percentage points short of the 40% tree-cover target set for this area.
How many more trees does Deoria need?
Deoria needs roughly 50,894 more trees to close a 16-point shortfall against its 40% tree-cover target — about 1,120 t of extra CO₂ absorbed per year once grown.
How are Deoria'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 Pathar Deva; the tree count is an estimate derived from that cover.
