How much forest has Kulti lost?
There was almost no forest around Kulti 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.
2017: satellite photo from January 2017 of a 5 × 5 km area in the city center.
Forest gained and lost, 2000–2020
- Forest in 2000
- 1,430 ha
- Forest in 2020
- 1,550 ha
- Overall change
- +116 hamore forest than in 2000
Comparing satellite maps from 2000 and 2020, the forest around Kulti grew from about 1,430 hectares to 1,550 hectares, a net gain of about 116 hectares (+8.1%). New forest grew on about 158 hectares, while 42 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 Kulti
What is the air quality (AQI) in Kulti right now?
The latest reading for Kulti shows an AQI of 158 (Unhealthy), measured Nov 11, 20:45 local time by 2 ground monitoring stations via OpenAQ (the median of their readings; the nearest is Evelyn Lodge, Asansol - WBPCB, 10.9 km away). The main pollutant is PM2.5. Everyone should limit long outdoor exertion; sensitive groups more so.
Is it safe to exercise outside in Kulti today?
At AQI 158 (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 Kulti been like this week?
Over the last 7 days, the CAMS air-quality model put Kulti's daily AQI at 149 on average, from 119 on Nov 9 to an hourly peak of 181 on Nov 6. On 7 of those days the average was above 100, unhealthy for sensitive groups.
Is Kulti'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 Kulti lost since 2001?
There was almost no forest around Kulti 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. Comparing satellite maps from 2000 and 2020, the forest around Kulti grew from about 1,430 hectares to 1,550 hectares, a net gain of about 116 hectares (+8.1%). New forest grew on about 158 hectares, while 42 hectares were lost.
What is the tree count in Kulti?
Kulti has an estimated 141,716 trees across the 12.54 km² of land measured — 45.2% tree cover, already past the 40% tree-cover target set for this area.
How many more trees does Kulti need?
Kulti has already reached its tree-cover target, so no additional trees are needed to close the gap.
How are Kulti's air quality and tree cover measured?
Air quality is measured by ground monitoring stations near Kulti, 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 Kulti; the tree count is an estimate derived from that cover.
