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

Forest gained and lost, 2000–2020
- Forest in 2000
- 2,490 ha
- Forest in 2020
- 2,720 ha
- Overall change
- +234 hamore forest than in 2000
Comparing satellite maps from 2000 and 2020, the forest around Mumbai grew from about 2,490 hectares to 2,720 hectares, a net gain of about 234 hectares (+9.4%). New forest grew on about 274 hectares, while 40 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 Mumbai
What is the air quality (AQI) in Mumbai right now?
The latest reading for Mumbai shows an AQI of 129 (Unhealthy for sensitive groups), measured Nov 11, 20:00 local time by 11 ground monitoring stations via OpenAQ (the median of their readings; the nearest is Bandra Kurla Complex, Mumbai - MPCB, 2 km away). The main pollutant is PM2.5. Sensitive groups should limit long or intense outdoor activity.
Is it safe to exercise outside in Mumbai today?
At AQI 129 (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 Mumbai been like this week?
Over the last 7 days, the CAMS air-quality model put Mumbai's daily AQI at 136 on average, from 130 on Nov 11 to an hourly peak of 174 on Nov 9. On 7 of those days the average was above 100, unhealthy for sensitive groups.
Is Mumbai'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 Mumbai lost since 2001?
There was almost no forest around Mumbai 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 Mumbai grew from about 2,490 hectares to 2,720 hectares, a net gain of about 234 hectares (+9.4%). New forest grew on about 274 hectares, while 40 hectares were lost.
What is the tree count in Mumbai?
Mumbai has an estimated 45,874 trees across the 12.32 km² of land measured — 14.9% tree cover, 20 percentage points short of the 35% tree-cover target set for this area.
How many more trees does Mumbai need?
Mumbai needs roughly 61,883 more trees to close a 20-point shortfall against its 35% tree-cover target — about 1,361 t of extra CO₂ absorbed per year once grown.
How are Mumbai's air quality and tree cover measured?
Air quality is measured by ground monitoring stations near Lower Parel, 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 Lower Parel; the tree count is an estimate derived from that cover.
