Wide parts of the cultivated arid area over the globe are characterized by loamy soils. The combination of climate extremes, soil with high content of fine particles, a hilly topography, intense cultivations, and local farmers that are often unaware of soil conservation practices leads to enhanced soil erosion and incision phenomena (Catt, 2001, Sun et al., 2014). As for climate regimes, they have the strongest correlations in arid or cold regions, and weaker correlations in humid, temperate locations. While remotely sensed soil moisture data are less reliable in dense vegetation, these results confirm that drier, less vegetated climates show a highly linear relationship between soil moisture and rainfall.
