Overall change

Comparing satellite maps from 2000 and 2020, the forest around Loa Janan shrank from about 13,100 hectares to 8,380 hectares, a net loss of about 4,740 hectares (−36%). New forest grew on about 559 hectares, but 5,300 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 Loa Janan

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

The latest reading for Loa Janan shows an AQI of 58 (Moderate), measured Nov 11, 21:00 local time by the Samarinda, Indonesia ground monitoring station, 13.1 km away, via OpenAQ. The main pollutant is PM2.5. Unusually sensitive people should consider limiting long outdoor exertion.

Is it safe to exercise outside in Loa Janan 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 Loa Janan been like this week?

Over the last 7 days, the CAMS air-quality model put Loa Janan's daily AQI at 61 on average, from 45 on Nov 9 to an hourly peak of 122 on Nov 5. No day averaged above 100, the level where the air turns unhealthy for sensitive groups.

Is Loa Janan'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 Loa Janan lost since 2001?

Since 2001, the area within 10 km of Loa Janan has lost about 8,290 hectares of forest (about 12,000 football pitches): 44% of the forest it had in 2000. Most of it (over 99%) was deforestation, forest cleared for good, mainly for mining and energy. Forest loss is slowing down: about 193 hectares a year in 2021–2025, down from 527 hectares a year in 2016–2020. Comparing satellite maps from 2000 and 2020, the forest around Loa Janan shrank from about 13,100 hectares to 8,380 hectares, a net loss of about 4,740 hectares (−36%). New forest grew on about 559 hectares, but 5,300 hectares were lost.

What is the tree count in Loa Janan?

Loa Janan has an estimated 106,679 trees across the 11.09 km² of land measured — 38.5% tree cover, already past the 30% tree-cover target set for this area.

How many more trees does Loa Janan need?

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

How are Loa Janan's air quality and tree cover measured?

Air quality is measured by ground monitoring stations near Kecamatan Loa Janan Ilir, via OpenAQ; the 7-day trend is the Open-Meteo / CAMS model's estimate. 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 Kecamatan Loa Janan Ilir; the tree count is an estimate derived from that cover.
