Comparing satellite maps from 2000 and 2020, the forest around Sampit shrank from about 18,000 hectares to 8,730 hectares, a net loss of about 9,240 hectares (−51%). New forest grew on about 1,580 hectares, but 10,800 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 Sampit

What is the air quality (AQI) in Sampit right now?

The latest reading for Sampit shows an AQI of 77 (Moderate), observed Nov 11, 15:00 local time via Open-Meteo / CAMS, corrected with 3 ground-station cities within 245 km, 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 Sampit today?

At AQI 77 (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 Sampit been like this week?

Over the last 7 days, the CAMS air-quality model put Sampit's daily AQI at 78 on average, from 54 on Nov 11 to an hourly peak of 170 on Nov 6. On 1 of those days the average was above 100, unhealthy for sensitive groups.

Is Sampit'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 Sampit lost since 2001?

Since 2001, the area within 10 km of Sampit has lost about 16,300 hectares of forest (about 23,000 football pitches): 62% of the forest it had in 2000. Most of it (56%) was deforestation, forest cleared for good, mainly for farms, pasture and plantations. Forest loss is slowing down: about 190 hectares a year in 2021–2025, down from 445 hectares a year in 2016–2020. Comparing satellite maps from 2000 and 2020, the forest around Sampit shrank from about 18,000 hectares to 8,730 hectares, a net loss of about 9,240 hectares (−51%). New forest grew on about 1,580 hectares, but 10,800 hectares were lost.

What is the tree count in Sampit?

Sampit has an estimated 70,161 trees across the 12.21 km² of land measured — 23.0% tree cover, 7 percentage points short of the 30% tree-cover target set for this area.

How many more trees does Sampit need?

Sampit needs roughly 21,353 more trees to close a 7-point shortfall against its 30% tree-cover target — about 469.8 t of extra CO₂ absorbed per year once grown.

How are Sampit'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 Sampit; the tree count is an estimate derived from that cover.
