Deforestation · 2001–2025

How much forest has Uluberiya lost?

Since 2001, the area within 10 km of Uluberiya has lost about 3 hectares of forest (about 4 football pitches): under 1% of the forest it had in 2000. The biggest cause was towns and roads (14%). Almost none of it was deforestation, meaning forest cleared for good.

Comparing satellite maps from 2000 and 2020, the forest around Uluberiya grew from about 13,300 hectares to 13,700 hectares, a net gain of about 399 hectares (+3%). New forest grew on about 416 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 Uluberiya

What is the air quality (AQI) in Uluberiya right now?

The latest reading for Uluberiya shows an AQI of 91 (Moderate), measured Nov 11, 19:30 local time by the Padmapukur, Howrah - WBPCB ground monitoring station, 21.3 km away, via OpenAQ. The main pollutant is PM10. Unusually sensitive people should consider limiting long outdoor exertion.

Is it safe to exercise outside in Uluberiya today?

At AQI 91 (Moderate): fine for most people; unusually sensitive people should take long or hard exercise easier. Windows: fine to open; close them if you are sensitive to pollution. Masks: not needed for most people. The reading changes through the day, so check again before a long run or ride.

What has the air quality in Uluberiya been like this week?

Over the last 7 days, the CAMS air-quality model put Uluberiya's daily AQI at 187 on average, from 161 on Nov 9 to an hourly peak of 255 on Nov 8. On 7 of those days the average was above 100, unhealthy for sensitive groups.

Is Uluberiya'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 Uluberiya lost since 2001?

Since 2001, the area within 10 km of Uluberiya has lost about 3 hectares of forest (about 4 football pitches): under 1% of the forest it had in 2000. The biggest cause was towns and roads (14%). Almost none of it was deforestation, meaning forest cleared for good. Comparing satellite maps from 2000 and 2020, the forest around Uluberiya grew from about 13,300 hectares to 13,700 hectares, a net gain of about 399 hectares (+3%). New forest grew on about 416 hectares, while 17 hectares were lost.

What is the tree count in Uluberiya?

Uluberiya has an estimated 237,999 trees across the 12.43 km² of land measured — 76.6% tree cover, already past the 30% tree-cover target set for this area.

How many more trees does Uluberiya need?

Uluberiya has already reached its tree-cover target, so no additional trees are needed to close the gap.

How are Uluberiya's air quality and tree cover measured?

Air quality is measured by ground monitoring stations near Nimdighi, 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 Nimdighi; the tree count is an estimate derived from that cover.
