Deforestation · 2001–2025
How much forest has Nellore lost?
Since 2001, the area within 10 km of Nellore has lost about 3 hectares of forest (about 4 football pitches): 2.9% of the forest it had in 2000. The biggest cause was farms, pasture and plantations (23%). Almost none of it was deforestation, meaning forest cleared for good.

Comparing satellite maps from 2000 and 2020, the forest around Nellore grew from about 398 hectares to 546 hectares, a net gain of about 148 hectares (+37%). New forest grew on about 168 hectares, while 20 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 Nellore
What is the air quality (AQI) in Nellore right now?
The latest reading for Nellore shows an AQI of 161 (Unhealthy), measured Nov 11, 21:30 local time by the Ambedkar Nagar, Nellore - APPCB ground monitoring station, 2.5 km away, via OpenAQ. The main pollutant is PM2.5. Everyone should limit long outdoor exertion; sensitive groups more so.
Is it safe to exercise outside in Nellore today?
At AQI 161 (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 Nellore been like this week?
Over the last 7 days, the CAMS air-quality model put Nellore's daily AQI at 98 on average, from 32 on Nov 5 to an hourly peak of 161 on Nov 9. On 4 of those days the average was above 100, unhealthy for sensitive groups.
Is Nellore'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 Nellore lost since 2001?
Since 2001, the area within 10 km of Nellore has lost about 3 hectares of forest (about 4 football pitches): 2.9% of the forest it had in 2000.

Comparing satellite maps from 2000 and 2020, the forest around Nellore grew from about 398 hectares to 546 hectares, a net gain of about 148 hectares (+37%).

What is the tree count in Nellore?
Nellore has an estimated 42,619 trees across the 12.18 km² of land measured — 14.0% tree cover, 26 percentage points short of the 40% tree-cover target set for this area.
How many more trees does Nellore need?
Nellore needs roughly 79,149 more trees to close a 26-point shortfall against its 40% tree-cover target — about 1,741 t of extra CO₂ absorbed per year once grown.
How are Nellore's air quality and tree cover measured?
Air quality is measured by ground monitoring stations near Ramamurthy 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 Ramamurthy Nagar; the tree count is an estimate derived from that cover.
