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

- +422 hamore forest than in 2000
Comparing satellite maps from 2000 and 2020, the forest around Tangerang grew from about 4,350 hectares to 4,770 hectares, a net gain of about 422 hectares (+9.7%). New forest grew on about 487 hectares, while 66 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.

What has the air quality in Tangerang been like this week?
Over the last 7 days, the CAMS air-quality model put Tangerang's daily AQI at 132 on average, from 119 on Nov 9 to an hourly peak of 175 on Nov 10. On 7 of those days the average was above 100, unhealthy for sensitive groups.
Is Tangerang's AQI the same as Indonesia's ISPU?
No. Airleaf shows the US EPA Air Quality Index (AQI), the scale used by IQAir and most air-quality apps. Indonesia's official index is the ISPU (Indeks Standar Pencemar Udara), published by the environment ministry from its own monitoring stations. Its bands are 0–50 Baik (good), 51–100 Sedang (moderate), 101–200 Tidak Sehat (unhealthy), 201–300 Sangat Tidak Sehat (very unhealthy) and over 300 Berbahaya (hazardous). The two indexes use different breakpoints and averaging times, so the same air can score differently on each.
