  abstract = {{O}ver the past decades, drought has become a major concern in {M}orocco due to the importance of agriculture in the economy of the country. {I}n the present work, the standardized precipitation index ({SPI}) is used to monitor the evolution, frequency, and severity of droughts in the {H}igh {A}tlas basins ({N}'{F}is, {O}urika, {R}heraya, {Z}at, and {R}'dat), located south of {M}arrakech city. {T}he spatiotemporal characterization of drought in these basins is performed by computing the {SPI} with precipitation spatially interpolated over the catchments. {T}he {H}aouz plain, located downstream of these basins, is strongly dependent on water provided by the mountain ranges, as shown by the positive correlations between the normalized difference vegetation index ({NDVI}) in the plain and the 3, 6, and 12-month {SPI} in the {H}igh {A}tlas catchments. {O}n the opposite, no significant correlations are found with piezometric levels of the {H}aouz groundwater due to intensified pumping for irrigation in the recent decades. {A} relative {SPI} index was computed to evaluate the climate change impacts on drought occurrence, based on the projected precipitation (2006-2100) from five high-resolution {CORDEX} regional climate simulations, under two emission scenarios ({RCP} 4.5 and {RCP} 8.5). {T}hese models show a decrease in precipitation towards the future up to -65% compared to the historical period. {I}n terms of drought events, the future projections indicate a strong increase in the frequency of {SPI} events below -2, considered as severe drought condition.},
