How much forest has Chūru lost?
There was almost no forest around Chūru 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.

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 Chūru
What is the air quality (AQI) in Chūru right now?
The latest reading for Chūru shows an AQI of 343 (Hazardous), measured Nov 11, 20:00 local time by the Subash Chowk, Churu - RSPCB ground monitoring station, 1 km away, via OpenAQ. The main pollutant is PM10. Emergency conditions — avoid outdoor activity.
Is it safe to exercise outside in Chūru today?
At AQI 343 (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 Chūru been like this week?
Over the last 7 days, the CAMS air-quality model put Chūru's daily AQI at 167 on average, from 137 on Nov 8 to an hourly peak of 205 on Nov 10. On 7 of those days the average was above 100, unhealthy for sensitive groups.
Is Chūru'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 Chūru lost since 2001?
There was almost no forest around Chūru 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.

How many more trees does Chūru need?
Chūru needs roughly 113,097 more trees to close a 36-point shortfall against its 45% tree-cover target — about 2,488 t of extra CO₂ absorbed per year once grown.
How are Chūru's air quality and tree cover measured?
Air quality is measured by ground monitoring stations near Prathiba Nagar, 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 Prathiba Nagar; the tree count is an estimate derived from that cover.
