In arid and semi-arid environments, the characterization of the inter-annual variations of the light use efficiency ε due to water stress still relies mostly on meteorological data. Thus the GPP estimation based on procedures exclusively driven by remote sensing data has not found yet a widespread use. In this work, the potential to characterize the water stress in semi-natural vegetation of th...

Present-day climate cannot account for the presence of such lakes in the arid to semi arid area of Jordan. Therefore more intense and wetter Mediterranean cyclones in winter coupled with Arabian monsoon or even ArabianIndian monsoon in summer would have affected major parts of Jordan up to latitude 31° 32 ́ during the warmer periods of the Pleistocene and brought more rain to establish and susta...
