EventA study published on 5 August 2026 by Sun Yat‑sen University and collaborators analyzed 21 402 km² of Arctic human‑footprint areas at 30‑m resolution. It shows climate‑driven greening alongside human‑driven browning, with disturbance accounting for 16.1 % of greenness variability and causing an average browning of −109.7×10⁻⁴ NDVI per year versus stable areas greening at 37.8×10⁻⁴ NDVI per year. The results underscore that Arctic vegetation change cannot be described by uniform greening alone.
A multi‑university study quantified the impact of human disturbance on Arctic vegetation. Mapping 21,402 km² of human‑footprint areas with 30‑m resolution, researchers found that anthropogenic activities caused browning that offsets climate‑driven greening trends, urging more nuanced ecosystem management.
