  abstract = {{B}aseflow is an important water resource because it supplies streamflow between precipitation events and during dry seasons. {W}e report the first continental assessment of baseflow in {A}frica by analyzing the baseflow index, baseflow seasonality, and monthly baseflow trends for three periods (1950-2018, 1950-1980, and 1981-2018). {T}o explain changes in baseflow, we analyze precipitation trends. {R}esults highlight that the baseflow season in west-central {A}frica occurs during {A}ugust-{N}ovember. {I}n southern and northern {A}frica, the baseflow season is similar ({J}anuary-{M}ay and {J}anuary-{A}pril, respectively). {T}rend analysis detected monthly baseflow decreases in west-central {A}frica over the entire record and from 1950 to 1980, with increases after 1980. {A} clear pattern was absent in southern {A}frica for the whole record, but increases were detected earlier and decreases from 1981 to 2018. {I}n northern {A}frica, decreasing baseflow trends were pronounced over the whole record, with no clear shift present. {P}recipitation trends were only consistent with baseflow changes in west-central {A}frica},
