A grid cell is labeled as frontier if it experiences 0.5% percentage points loss in 5 consecutive years
Years available: 2000, 2010, 2020, 2025.
The year in the time series when frontier dynamics emerge in a frontier cell,
defined as the year with the highest loss rate in the 5-year window in which a frontier cell was identified.
2000: manually identified centers of assumed agricultural frontiers in 2000 2025: frontier region evolution based on the frontier onset metric, using three sets of rules:
(1) region growing, (2) region merging, (3) new emerging regions
Random Colors visualize the different regions.
Frontier regions 2025 classified into four categories based on
(a) deforestation rates inside the regions
(b) growth rate of the region
See Exemplary categorization ruleset. Can be fully adjusted based on feedback.
