  abstract = {{T}he rainfall erosivity factor ({R} factor in {U}niversal {S}oil {L}oss {E}quation), denoting rain energy, is a key factor for soil loss modeling. {I}ts present and future estimation is thus significant for any action related to soil and water conservation and planning. {T}he extended series of precipitations at high temporal resolution, essential to its evaluation, are not readily available in {M}orocco. {T}he objective of this study is to predict the evolution of rainfall erosivity by 2080 in the {W}estern {R}if, based on predictions of daily rain provided by the {G}eneral {C}limatic {M}odels ({GCM}s). {T}o reflect the seasonal variability of rainfall, and thus of {R} factor, a series of instantaneous rain measured over 35 consecutive years was used to monthly calibrate a model to calculate erosivity based of daily rainfall. {T}he application of this model to the predictions of different {GCM}s and for various scenarios of climate evolution in {W}estern {R}if shows a weak evolution of erosivity on an annual timescale but a very strong evolution of the latter according to seasons with a reduction in {R} factor during winter and spring, and a pronounced increase during summer and autumn. {T}his discernable change of the seasonality of rainfall erosivity is very useful for adjusting the evolution of agricultural practices and for selecting appropriate soil protection measures.},
