Deforestation · 2001–2025
How much forest has Dam Dam lost?
Since 2001, the area within 10 km of Dam Dam has lost about 3 hectares of forest (about 5 football pitches): 1.8% of the forest it had in 2000. The biggest cause was towns and roads (2.9%). Almost none of it was deforestation, meaning forest cleared for good.

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

- Forest in 2020

- +6 hamore forest than in 2000
Comparing satellite maps from 2000 and 2020, the forest around Dam Dam stayed about the same size, at about 5,180 hectares: new forest grew on about 137 hectares, and about 130 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 Dam Dam
What is the air quality (AQI) in Dam Dam right now?
The latest reading for Dam Dam shows an AQI of 111 (Unhealthy for sensitive groups), measured Nov 11, 20:30 local time by 4 ground monitoring stations via OpenAQ (the median of their readings; the nearest is Belur Math, Howrah - WBPCB, 7.3 km away). The main pollutant is PM2.5. Sensitive groups should limit long or intense outdoor activity.
Is it safe to exercise outside in Dam Dam today?
At AQI 111 (Unhealthy for sensitive groups): children, older adults and people with asthma or heart disease should cut down long or hard exercise. Windows: close them to keep the outside air out. Masks: sensitive groups: an N95 outdoors. The reading changes through the day, so check again before a long run or ride.
What has the air quality in Dam Dam been like this week?
Over the last 7 days, the CAMS air-quality model put Dam Dam's daily AQI at 178 on average, from 154 on Nov 9 to an hourly peak of 241 on Nov 8. On 7 of those days the average was above 100, unhealthy for sensitive groups.
Is Dam Dam'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 Dam Dam lost since 2001?
Since 2001, the area within 10 km of Dam Dam has lost about 3 hectares of forest (about 5 football pitches): 1.8% of the forest it had in 2000. The biggest cause was towns and roads (2.9%). Almost none of it was deforestation, meaning forest cleared for good. Comparing satellite maps from 2000 and 2020, the forest around Dam Dam stayed about the same size, at about 5,180 hectares: new forest grew on about 137 hectares, and about 130 hectares were lost.
What is the tree count in Dam Dam?
Dam Dam has an estimated 118,352 trees across the 12.49 km² of land measured — 37.9% tree cover, already past the 35% tree-cover target set for this area.
How many more trees does Dam Dam need?
Dam Dam has already reached its tree-cover target, so no additional trees are needed to close the gap.
How are Dam Dam's air quality and tree cover measured?
Air quality is measured by ground monitoring stations near Cantonment, 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 Cantonment; the tree count is an estimate derived from that cover.
