“…5b) that show high-energy-deposited-sediments occurring at the same time as E1 and E2, suggesting a regional forcing causing these marine transgressions. These on-shore deposits were reported in the form of fine sediments layers at the estuaries of Tahaddart (35.5° N) 10,72 and Loukkos (35.15° N) 4 and at the Moulay-Bousalham (34°N) and Oualidia (32°N) lagoons 38,39,54 , and marine gastropods shells deposited at Moulay Douraïne (31° N) 73 . Biogeographic evidence from the NW African coast (28 -19° N) suggests a transgression event taking place around 3.5 kyrs BP 74 , also recorded by wetlands on the Atlantic coast of Spain in addition to another one around 2.8 kyrs BP [75][76][77] .…”

The paleoenvironmental changes recorded at the Khnifiss Lagoon, on the Saharan Atlantic coast, southern Morocco, during the last 3.5 kyrs BP puts another piece to the puzzle on the intricate relationship between North Atlantic climate patterns and climate variations in Northwest Africa. This study shed light on the hydroclimatic dynamics during a pivotal climatic period: the transition from the mid- to late Holocene and the termination of the African Humid Period. Our research unveils two key periods of salt marsh expansion at the Khnifiss Lagoon, approximately 3.5 and 2.7 kyrs BP when humidity conditions and increased marine influence were recorded. Those conditions paint a scenario of increased storminess and precipitation in NW Africa, compatible with a negative NAO-like climatic configuration. Our data revealed a synchronization between this scenario in NW Africa and cooling events in the North Atlantic during the transition from the mid-to-late Holocene, related to Rapid Climate Changes (RCCs) occurring between 3.5 and 2.5 kyrs BP, also known as the Bond event #2. These findings can potentially enhance climate prediction models, offering opportunities to better prepare for and adapt to the evolving climate patterns in the region. High-resolution paleoenvironmental records are still rare in Northwest Africa and are highly needed. The knowledge gained from these studies represents a critical step towards addressing the climate challenges in Northwest Africa and fortifying the region’s resilience in the face of climate change.

“…Primary lands are heavily folded, tectonized and leveled off (Combe, 1963). Between the first cordon and a line of dead cliffs, there is a gutter or furrow, a depression more or less parallel to the rib line, commonly called « Oulja » (Figure 2) (Guilcher and Joly, 1954;Weisrock, 1980;Weisrock and Fontugne, 1991).…”

the DRASTIC method was chosen because it can be adapted to different environments and because it combines the seven criteria that directly influence groundwater: depth, recharge, geology, soil, slope, unsaturated zone and conductivity. Located in the North West of Morocco, the Temara aquifer is a very important water resource, but it is overexploited and deteriorated as never before. This issue is of concern to decision-makers in the field of water management. The objective of this work is to create a map of vulnerability to pollution by the Bay of Geographic Information Systems (GIS) and the DRASTIC model. Thus, the highest vulnerabilities are located around the drinking water treatment plant of Ain Atiq, at the mouth of the Bouregreg River and scattered in places throughout the study area. The results of the physico-chemical analysis showed compatibility with the results of the DRASTIC model.
