  abstract = {{C}arbon dioxide emissions to the atmosphere from inland waters-streams, rivers, lakes and reservoirs-are nearly equivalent to ocean and land sinks globally. {I}nland waters can be an important source of methane and nitrous oxide emissions as well, but emissions are poorly quantified, especially in {A}frica. {H}ere we report dissolved carbon dioxide, methane and nitrous oxide concentrations from 12 rivers in sub-{S}aharan {A}frica, including seasonally resolved sampling at 39 sites, acquired between 2006 and 2014. {F}luxes were calculated from published gas transfer velocities, and upscaled to the area of all sub-{S}aharan {A}frican rivers using available spatial data sets. {C}arbon dioxide-equivalent emissions from river channels alone were about 0.4 {P}g carbon per year, equivalent to two-thirds of the overall net carbon land sink previously reported for {A}frica. {I}ncluding emissions from wetlands of the {C}ongo river increases the total carbon dioxide-equivalent greenhouse-gas emissions to about 0.9 {P}g carbon per year, equivalent to about one quarter of the global ocean and terrestrial combined carbon sink. {R}iverine carbon dioxide and methane emissions increase with wetland extent and upland biomass. {W}e therefore suggest that future changes in wetland and upland cover could strongly affect greenhouse-gas emissions from {A}frican inland waters.},
