are more complex than the 'wet get wetter, dry get drier'  paradigm. This is also supported by remote sensing data, with ESA CCI data for 1979-2013 showing only 15% of land following the WGWDGD paradigm for soil moisture . Defining arid, humid and transitional areas according to precipitation and temperature regimes, all three classes of regions see more widespread trends of declining soil moisture than increasing soil moisture . In the ESA CCI product, increasing soil moisture trends are mainly seen in humid or transitional areas and are rare in arid regions
