Estimation of actual evapotranspiration (AET) and its spatial distribution are important to understanding of catchment hydrology. The AET is driven by net energy available to evaporate water from soil and vegetation surfaces, and to transpirate water from vegetation. However, estimating AET is di...

The study examines the global pattern and impacts of droughts through mapping several drought-related characteristics - either at a country level or at regular grid scales. It appears that arid and semi-arid areas also tend to have a higher probability of drought occurrence. It is illustrated tha...
