The perennial and seasonal wetland diversity of the Moroccan Middle Atlas region provides a valuable "test-bed" for understanding the response of different hydrosystems to climatic variations. A multiproxy study, based on sedimentological description

The 4.2 kyrs event, used as a marker of holocene stratigraphy, has been described as a rapid climate change in the northern hemisphere triggering droughts in the Mediterranean region. However, the severity and geographical extent of this event are st
