Nonlinear response of soil moisture drought persistence to climatic aridity at the global scale

Soil moisture deficit persistence affects drought development, ecosystem resilience, and land–atmosphere feedbacks, but its dependence on climatic aridity is still not well understood at the global scale. We examine whether persistence changes gradually along the aridity gradient...

Machine Learning-Based Assessment of Land-Use Change, Forest Recovery, and Landscape Connectivity in Islamabad

LULCC is a major driver of habitat fragmentation, biodiversity loss, and declining landscape connectivity, particularly in rapidly urbanizing regions. Although Islamabad has experienced substantial urban expansion and forest-cover change, long-term city-scale assessments linking...
