In recent decades, drought has become a significant phenomenon attributed to climate change variability. Its long-term repercussions can lead to substantial agricultural, hydrological, social, and economic consequences. This study uses the Standardized Precipitation Index (SPI) to assess drought in Morocco’s SoussMassa watershed, revealing a significant decline in annual precipitation and highlighting the region’s increased drought susceptibility. Specifically, we analyzed data from five weather stations: Amaghouz (1978-2016), Amsoul (1979-2016), Immerguen (1971-2016), Lamded (1982-2016), and Taroudant (1967-2016) using statistical methods recommended by the World Meteorological Organization (WMO) for annual rainfall records. Additionally, we applied the SPI over a 12-month period to identify dry and wet years. Our analysis reveals alternating dry and wet phases, characterized by an overall decline in annual precipitation.
