In short
23 mining permits lie in this area.
Mining footprint (satellite)
13.3 ha of the 492,938 ha (0%) shows mining disturbance on satellite images.[3]0.2 ha of it lies outside known permit boundaries (ESDM). This is not a finding of illegality.

The total counts land once where sources overlap (Cheng et al. 2026, then Maus et al. 2022, then ESMI digitised).
Outside known permit boundaries is not a finding of illegality: it can be a gap in the ESDM permit layer, an older or expired permit, or another land use.
Forest loss
Tree-cover loss 2001–2025, where tree cover in 2000 was at least 30 %. Annual satellite data (Hansen / University of Maryland).
Loss means tree cover was removed: clearing, but also plantation harvest or fire. It is not a finding of illegal deforestation, and the data is yearly, not monthly.

Footprint measure
Land inside the mapped mining footprint polygons that is abandoned and still bare or water.
No abandoned bare or water land in this measure here.
The two measures overlap. They are shown side by side and never added together. tn = trillion, bn = billion, m = million (rupiah). The letter after a figure is its grade (A best, D a rough model estimate); the range is P10–P90.
MapBiomas mining-class measure · Every 30 m pixel that MapBiomas ever labelled as a mining pit and that is now abandoned and still bare or water. 2.2 ha still bare and 1.3 ha water (pit lakes).
From value now to net gain
Value now → value after restoration, plus what restoration adds for everyone, minus the costs, gives the net gain.

Land value
Kabupaten Tanjung Jabung Barat · Rp per m², market-equivalent today: P50 with the P10–P90 band
Model: comparable agriculture land Rp 9,108/m² minus expected reclamation ≈ Rp 18,394/m² (coal). Reclamation costs more than the land is worth: net −Rp 10,054/m², so its value is 0 (79% of model runs negative).
NJOP and compensation values are converted to market-equivalent and older years CPI-indexed. A fallback value is borrowed from a wider area and has a wider band and a lower grade. Not an appraisal. · landvalue.v1 · API (observations: Tier 1)

Grade C
Satellite column density, not air at ground level. Sentinel-5P (TROPOMI) measures the amount of NO₂ and SO₂ in the whole air column. The figure is the ENHANCEMENT over the surrounding background, not a ground-level concentration and not a health exposure value. The zone is named by place; this is not a finding about any company.

Monthly NO₂ enhancement (thin), 12-month running mean (bold), ± 1 SE band; 0 = background
SO₂ for this place is not available yet (sampled orbits still being processed).
The ±SE is statistical only; the retrieval (air-mass factor) uncertainty is 25–50 % for NO₂ and larger for small SO₂ columns. No wind data is used yet: the background ring covers all directions.
