Deforestation · 2001–2025
Which has lost more forest, Jakarta or Palembang?
Palembang has lost more: about 5,540 ha of forest within 10 km of its center from 2001 to 2025, against 7 ha around Jakarta. 5,180 ha of that was cleared for good, for farms, mines or towns.
Measured within 10 km of each center, from the yearly satellite maps of forest loss: a wider circle than the one for tree cover, because forest is usually lost at a city's edges.
Worst year: 2006, with 3 ha lost.
Worst year: 2012, with 570 ha lost.

Reading these numbers
How this comparison is made
Air quality index
The US EPA index, computed from current pollutant concentrations: ground stations where a place has them nearby, and the CAMS atmospheric model everywhere else. It moves hour to hour, so it is a snapshot rather than a verdict on either place. The guideline marks are from the WHO's 2021 air quality guidelines.
Trees and forest
Tree cover is the share of ground under canopy within 2 km of each center, read from Sentinel-2 satellite imagery at 10 m detail. It measures that circle, not the whole municipality, which is what makes the two comparable. Forest loss comes from the University of Maryland's Global Forest Change maps.

Palembang has more tree cover: 24.6% of the land within 2 km of its center against 17.8% around Jakarta, or about 77,283 trees against 55,697. Both figures describe the same-sized circle of ground around each center, not the whole municipality.
How many more trees do Jakarta and Palembang need?
Jakarta needs about 53,819 more to reach its canopy target of 35%, and Palembang about 48,381 to reach 40%. The target starts at 30% of the land and rises where air quality is poor.
Are Jakarta and Palembang measured the same way?
The method is the same: the US EPA index for air, and Sentinel-2 satellite imagery at 10 m detail over an identical radius for trees. Both readings come from nearby ground stations. Nothing is adjusted for population, city limits or climate.
How often does the Jakarta vs Palembang comparison update?
The air readings refresh about once an hour, and each reading's local time is shown at the top of the page. Tree cover comes from the latest clear satellite image of each area (Sep 5, 2026 and Sep 8, 2026), and the forest figures are published yearly.
