Aperiodic Clustered and Periodic Hexagonal Vegetation Spot Arrays Explained by Inhomogeneous Environments and Climate Trends in Arid Ecosystems

open access: yesGeophysical Research Letters, Volume 52, Issue 21, 16 November 2025.
Abstract Due to climate change, overgrazing, and deforestation, arid ecosystems are vulnerable to desertification and land degradation. As aridity increases, vegetation cover loses spatial homogeneity and self‐organizes into heterogeneous vegetation patterns, a step before a catastrophic shift to bare soil.
