  abstract = {{T}he seasonal snow in the {P}yrenees {M}ountains is an essential source of runoff for hydropower production and crop irrigation in {S}pain and {F}rance. {T}he {P}yrenees are expected to undergo strong environmental perturbations over the 21st century because of climate change (rising temperatures) and the abandonment of agro-pastoral areas (reforestation). {B}oth changes are happening at similar timescales and are expected to have an impact on snow cover. {T}he effect of climate change on snow in the {P}yrenees is well understood, but the effect of land cover changes is much less documented. {H}ere, we analyze the response of snow cover to a combination of climate and land cover change scenarios in a small {P}yrenean catchment ({B}assies, 14.5 km(2), elevation range 940-2651 m a.s.l.) using a distributed snowpack evolution model. {C}limate scenarios were constructed from the output of regional climate model projections, whereas land cover scenarios were generated based on past observed changes and an inductive pattern-based model. {T}he model was validated over a snow season using in situ snow depth measurements and high-resolution snow cover maps derived from {SPOT} ({S}atellite {P}our l'{O}bservation de la {T}erre - {E}arth {O}bservation {S}atellite) satellite images. {M}odel projections indicate that both climate and land cover changes reduce the mean snow depth. {H}owever, the impact on the snow cover duration is moderated in reforested areas by the shading effect of trees on the snow surface radiation balance. {M}ost of the significant changes are expected to occur in the transition zone between 1500 m a.s.l. and 2000 m a.s.l. where (i) the projected increase in air temperatures decreases the snow fraction of the precipitation and (ii) the land cover changes are concentrated. {H}owever, the consequences on the runoff are limited because most of the meltwater originates from high-elevation areas of the catchment, which are less affected by climate change and reforestation.},
