Comparing satellite maps from 2000 and 2020, the forest around Bima shrank from about 10,900 hectares to 10,500 hectares, a net loss of about 379 hectares (−3.5%). New forest grew on about 291 hectares, but 670 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.

The latest reading for Bima shows an AQI of 58 (Moderate), observed Nov 10, 21:00 local time via Open-Meteo / CAMS, US EPA index. The main pollutant is PM2.5. Unusually sensitive people should consider limiting long outdoor exertion.
Is it safe to exercise outside in Bima today?
At AQI 58 (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 Bima been like this week?
Over the last 7 days, the CAMS air-quality model put Bima's daily AQI at 51 on average, from 38 on Nov 4 to an hourly peak of 83 on Nov 6. No day averaged above 100, the level where the air turns unhealthy for sensitive groups.
Is Bima'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.
How much forest has the area around Bima lost since 2001?
Since 2001, the area within 10 km of Bima has lost about 557 hectares of forest (about 780 football pitches): 7.7% of the forest it had in 2000. Most of it (93%) was deforestation, forest cleared for good, mainly for farms, pasture and plantations. Comparing satellite maps from 2000 and 2020, the forest around Bima shrank from about 10,900 hectares to 10,500 hectares, a net loss of about 379 hectares (−3.5%). New forest grew on about 291 hectares, but 670 hectares were lost.
What is the tree count in Bima?
Bima has an estimated 54,155 trees across the 9.8 km² of land measured — 22.1% tree cover, 8 percentage points short of the 30% tree-cover target set for this area.
How many more trees does Bima need?
Bima needs roughly 19,358 more trees to close a 8-point shortfall against its 30% tree-cover target — about 425.9 t of extra CO₂ absorbed per year once grown.
How are Bima's air quality and tree cover measured?
Air quality comes from ground monitoring stations via OpenAQ where one reports nearby, and otherwise, as here, from the Open-Meteo / CAMS model, which may differ from street-level monitors. 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 Bima; the tree count is an estimate derived from that cover.
