Descriptif
A comprehensive review of various definitions of droughts has been presented to develop the basis for analysis of droughts. Using the specific definition of onset of rains in each year as the sowing date, the length of dry spells were calculated from the historical rainfall data for 150 stations located in Burkina Faso, Mali, Niger, and Senegal. Applications of the dry spell analysis for the choice of a crop/variety, supplemental irrigation and crop water requirements are described with examples. The text is supported by 310 tables and 17 graphs.
