  abstract = {{L}and degradation is intense in tropical regions where it causes for instance a decline in soil fertility and reservoir siltation. {T}wo fingerprinting approaches (i.e. the conventional approach based on radionuclide and geochemical concentrations and the alternative diffuse reflectance infrared {F}ourier transform spectroscopy method) were conducted independently to outline the sources delivering sediment to the river network draining into the {C}ointzio reservoir, in {M}exican tropical highlands. {T}his study was conducted between {M}ay and {O}ctober in 2009 in subcatchments representative of the different environments supplying sediment to the river network. {O}verall, {C}ointzio catchment is characterized by very altered soils and the dominance of {A}ndisols and {A}crisols. {B}oth fingerprinting methods provided very similar results regarding the origin of sediment in {H}uertitas subcatchment (dominated by {A}crisols) where the bulk of sediment was supplied by gullies. {I}n contrast, in {L}a {C}ortina subcatchment dominated by {A}ndisols, the bulk of sediment was supplied by cropland. {S}ediment originating from {P}otrerillos subcatchment characterized by a mix of {A}crisols and {A}ndisols was supplied in variable proportions by both gullies and rangeland/cropland. {I}n this latter subcatchment, results provided by both fingerprinting methods were very variable. {O}ur results outline the need to take the organic carbon content of soils into account and the difficulty to use geochemical properties to fingerprint sediment in very altered volcanic catchments. {H}owever, combining our fingerprinting results with sediment export data provided a way of prioritizing the implementation of erosion control measures to mitigate sediment supply to the {C}ointzio reservoir supplying drinking water to {M}orelia city.},
