Indonesia - Deforestation inside concession
Years available: 2015-2024
Data last updated: 5 Dec 2025
This metric represents the total deforestation of natural forests, occurring in a single year, within a specific concession. To calculate this metric, Gaveau et al. (2022) combines natural forests (as defined above) with the annual tree cover loss dataset developed by the University of Maryland (Hansen et al., 2013). The tree cover loss dataset measures the removal of trees (tree height >5 m) if the canopy cover falls below 30%. It does not distinguish between removal of natural forests and planted trees. Collaborators at TreeMap then conduct additional photo interpretation and analysis to filter out errors. The same data sources are used on The TreeMap’s mapping platform The TreeMap’s Nusantara Atlas (2025). The metric is available on Trase Supply Chain’s Sankey diagram for active concessions trading in the target year and for all concessions on the platform’s map tool.
