Map of 15 Ecoclimatic Arid and Semi-Arid zones in Africa (6°S-39°N)

Ecoclimatic Arid and Semi-Arid zones in Africa (6°S-39°N) based were derived from  a multiway analysis of the WorldClim database (1950-2000). See details in the paper: Leibovici DG, Quillevere G and Desconnets J-C (2007) A method to Classify Ecoclimatic Arid and Semi-Arid Zones in Circum-Saharan Africa Using Dynamics of Multiple Indicators. IEEE Transaction in Geoscience And Remote Sensing, 45(12), 4000-4007. doi:10.1109/TGRS.2007.908878
