Resumen:
ry subtropical regions (DST), originally hosting woodlands and savannas, are subject to contrasting human pressures
and land uses and different degrees of water limitation. We quantified how this variable context influences
landscape pattern and vegetation functioning, by exploring the associations between three groups of variables
describing (i) human pressures (population density, poverty, and market isolation) and climate (water availability),
(ii) landscape pattern (woody cover, infrastructure, paddock size, etc.), and (iii) vegetation functioning (magnitude
and stability of primary productivity), in regions of Asia, Africa, Australia, and America. We collected data from global
socioeconomic databases and remote sensing products for 4525 samples (representing uncultivated and cultivated
conditions), located along 35 transects spanning semiarid to subhumid conditions. A Reciprocal Averaging ordination
of uncultivated samples revealed a dominant gradient of declining woody c
