  abstract = {{S}orghum production system in the semi-arid region of {A}frica is characterized by low yields which are generally attributed to high rainfall variability, poor soil fertility, and biotic factors. {P}roduction constraints must be well understood and quantified to design effective sorghum-system improvements. {T}his study uses the state-of-the-art in silico methods and focuses on characterizing the sorghum production regions in {M}ali for drought occurrence and its effects on sorghum productivity. {F}or this purpose, we adapted the {APSIM}-sorghum module to reproduce two cultivated photoperiod-sensitive sorghum types across a latitude of major sorghum production regions in {W}estern {A}frica. {W}e used the simulation outputs to characterize drought stress scenarios. {W}e identified three main drought scenarios: (i) no-stress; (ii) early pre-flowering drought stress; and (iii) drought stress onset around flowering. {T}he frequency of drought stress scenarios experienced by the two sorghum types across rainfall zones and soil types differed. {A}s expected, the early pre-flowering and flowering drought stress occurred more frequently in isohyets < 600 mm, for the photoperiod-sensitive, late-flowering sorghum type. {I}n isohyets above 600 mm, the frequency of drought stress was very low for both cultivars. {W}e quantified the consequences of these drought scenarios on grain and biomass productivity. {T}he yields of the highly-photoperiod-sensitive sorghum type were quite stable across the higher rainfall zones > 600 mm, but was affected by the drought stress in the lower rainfall zones < 600 mm. {C}omparatively, the less photoperiod-sensitive cultivar had notable yield gain in the driest regions < 600 mm. {T}he results suggest that, at least for the tested crop types, drought stress might not be the major constraint to sorghum production in isohyets > 600 mm. {T}he findings from this study provide the entry point for further quantitative testing of the {G}enotype x {E}nvironment x {M}anagement options required to optimize sorghum production in {M}ali.},
