  abstract = {{O}ver recent decades, regions of {W}est and {C}entral {A}frica have experienced different and significant changes in climatic patterns, which have significantly impacted hydrological regimes. {S}uch impacts, however, are not fully understood at the regional scale, largely because of scarce hydroclimatic data. {T}herefore, the aim of this study is to (a) assemble a new, robust, reconstructed streamflow dataset of 152 gauging stations; (b) quantify changes in streamflow over 1950-2005 period, using these newly reconstructed datasets; (c) significantly reveal trends and variability in streamflow over {W}est and {C}entral {A}frica based on new reconstructions; and (d) assess the robustness of this dataset by comparing the results with those identified in key climatic drivers (e.g. precipitation and temperature) over the region. {G}ap filling methods applied to monthly time series (1950-2005) yielded robust results (median {K}ling-{G}upta {E}fficiency > 0.75). {T}he study underlines a good agreement between precipitation and streamflow trends and reveals contrasts between western {A}frica (negative trends) and {C}entral {A}frica (positive trends) in the 1950s and 1960s. {H}omogenous dry conditions of the 1970s and 1980s, characterized by reduced significant negative trends resulting from quasi-decadal modulations of the trend, are replaced by wetter conditions in the recent period (1993-2005). {T}he effect of this rainfall recovery (which extends to {W}est and {C}entral {A}frica) on increased river flows are further amplified by land use change in some {S}ahelian basins. {T}his is partially offset, however, by higher potential evapotranspiration rates over parts of {N}iger and {N}igeria. {C}rucially, the new reconstructed streamflow datasets presented here will be available for both the scientific community and water resource managers.},
