Tree cover grew on Afghan farmland—but that does not establish forest recovery
WHAT THE EVIDENCE SAYS
Three-meter satellite imagery and object-based classification tracked agricultural areas in four eastern Afghan districts from 2016 to 2024. Mapped tree cover rose from 369.26 to 502.58 hectares, a 36.1% increase, mainly through cropland-to-tree-cover transitions. Natural forests were excluded from the mapped areas; the paper's wider deforestation discussion draws on earlier regional evidence rather than a new measurement of surrounding forest loss. Classification agreement was 0.80 or higher.
WHY IT MATTERS / OUR READ
Tree-cover gain is a useful signal, but neither its cause nor its ecological value follows automatically. Distinguish deliberate planting from natural regrowth, and farm production from native-forest condition, before crediting a program or calling a landscape restored.
CAVEATS / UNCERTAINTY
These are selected agricultural areas in four districts, not complete district totals or a national forest estimate. Imagery alone could not distinguish deliberate planting from natural regeneration, quantify biodiversity or identify a causal effect of political change. Classification error and image timing remain limitations.

High-resolution satellite comparisons reveal agricultural tree gains that should not be mistaken for recovery of native forest.
