Résumé : As part of the development of high-resolution studies on past vegetation changes, palynological data allowed the reconstruction of vegetation evolution in Holocene sediments collected around the Sidi Ali el Mekki lagoon (N-E Tunisia). Our results show that over the last two millennia, vegetation changes in northern Tunisia reflect a complex relationship involving both natural forcings and human activity. The study of lagoon sediments highlighted that the maquis with olive and pistachio trees, which constituted the dominant vegetation around the Sidi Ali el Mekki lagoon during the first millennium of our era, have significantly declined in favor of grass and sagebrush steppes over the last 1000 years, indicating an increasing anthropogenic impact in the study area.
