Comparing satellite maps from 2000 and 2020, the forest around Rantauprapat shrank from about 29,300 hectares to 27,900 hectares, a net loss of about 1,390 hectares (−4.8%). New forest grew on about 790 hectares, but 2,180 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 Rantauprapat

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

The latest reading for Rantauprapat shows an AQI of 26 (Good), observed Nov 11, 06:00 local time via Open-Meteo / CAMS, corrected with 17 ground-station cities within 245 km, US EPA index. The main pollutant is PM2.5. Air quality is satisfactory for everyone.

Is it safe to exercise outside in Rantauprapat today?

At AQI 26 (Good): a good day to be active outside. Windows: open them to air the house. Masks: not needed. The reading changes through the day, so check again before a long run or ride.

What has the air quality in Rantauprapat been like this week?

Over the last 7 days, the CAMS air-quality model put Rantauprapat's daily AQI at 58 on average, from 49 on Nov 11 to an hourly peak of 94 on Nov 6. No day averaged above 100, the level where the air turns unhealthy for sensitive groups.

Is Rantauprapat'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 Rantauprapat lost since 2001?

Since 2001, the area within 10 km of Rantauprapat has lost about 11,200 hectares of forest (about 16,000 football pitches): 40% of the forest it had in 2000. Most of it (99%) was deforestation, forest cleared for good, mainly for farms, pasture and plantations. Forest loss has stayed about the same: about 518 hectares a year in 2021–2025, against 629 hectares a year in 2016–2020. Comparing satellite maps from 2000 and 2020, the forest around Rantauprapat shrank from about 29,300 hectares to 27,900 hectares, a net loss of about 1,390 hectares (−4.8%). New forest grew on about 790 hectares, but 2,180 hectares were lost.

What is the tree count in Rantauprapat?

Rantauprapat has an estimated 145,646 trees across the 12.53 km² of land measured — 46.5% tree cover, already past the 30% tree-cover target set for this area.

How many more trees does Rantauprapat need?

Rantauprapat has already reached its tree-cover target, so no additional trees are needed to close the gap.

How are Rantauprapat'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 South Rantau; the tree count is an estimate derived from that cover.
