- −363 haless forest than in 2000
Comparing satellite maps from 2000 and 2020, the forest around Cilacap shrank from about 8,600 hectares to 8,240 hectares, a net loss of about 363 hectares (−4.2%). New forest grew on about 171 hectares, but 534 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.

Is it safe to exercise outside in Cilacap today?
At AQI 84 (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 Cilacap been like this week?
Over the last 7 days, the CAMS air-quality model put Cilacap's daily AQI at 123 on average, from 92 on Nov 5 to an hourly peak of 200 on Nov 9. On 6 of those days the average was above 100, unhealthy for sensitive groups.
Is Cilacap'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 Cilacap lost since 2001?
Since 2001, the area within 10 km of Cilacap has lost about 392 hectares of forest (about 550 football pitches): 3.6% of the forest it had in 2000. Most of it (96%) was deforestation, forest cleared for good, mainly for farms, pasture and plantations. Comparing satellite maps from 2000 and 2020, the forest around Cilacap shrank from about 8,600 hectares to 8,240 hectares, a net loss of about 363 hectares (−4.2%). New forest grew on about 171 hectares, but 534 hectares were lost.
What is the tree count in Cilacap?
Cilacap has an estimated 40,702 trees across the 10.79 km² of land measured — 15.1% tree cover, 15 percentage points short of the 30% tree-cover target set for this area.
How many more trees does Cilacap need?
Cilacap needs roughly 40,163 more trees to close a 15-point shortfall against its 30% tree-cover target — about 883.6 t of extra CO₂ absorbed per year once grown.
How are Cilacap'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 Cilacap; the tree count is an estimate derived from that cover.
