- Overall change
- −1,320 haless forest than in 2000
Comparing satellite maps from 2000 and 2020, the forest around Sungailiat shrank from about 9,910 hectares to 8,590 hectares, a net loss of about 1,320 hectares (−13%). New forest grew on about 637 hectares, but 1,960 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.

Over the last 7 days, the CAMS air-quality model put Sungailiat's daily AQI at 56 on average, from 45 on Nov 11 to an hourly peak of 80 on Nov 6. No day averaged above 100, the level where the air turns unhealthy for sensitive groups.
Is Sungailiat'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 Sungailiat lost since 2001?
Since 2001, the area within 10 km of Sungailiat has lost about 3,060 hectares of forest (about 4,300 football pitches): 38% of the forest it had in 2000. Most of it (over 99%) was deforestation, forest cleared for good, mainly for farms, pasture and plantations. Forest loss is speeding up: about 153 hectares a year in 2021–2025, up from 99 hectares a year in 2016–2020. Comparing satellite maps from 2000 and 2020, the forest around Sungailiat shrank from about 9,910 hectares to 8,590 hectares, a net loss of about 1,320 hectares (−13%). New forest grew on about 637 hectares, but 1,960 hectares were lost.
What is the tree count in Sungailiat?
Sungailiat has an estimated 63,049 trees across the 9.63 km² of land measured — 26.2% tree cover, 4 percentage points short of the 30% tree-cover target set for this area.
How many more trees does Sungailiat need?
Sungailiat needs roughly 9,145 more trees to close a 4-point shortfall against its 30% tree-cover target — about 201.2 t of extra CO₂ absorbed per year once grown.
How are Sungailiat'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 Sungai Liat; the tree count is an estimate derived from that cover.
