This paper reports on two very different examples of Holocene sites where “humans and water” coexisted during dry periods, Key words: as observed by stratigraphic, archaeological and palynological evidence. Independent research was palaeoecology carried out on the Jefara Plain (Libya, 32°N) and the Gobero area (Niger, 17°N), at the extreme pollen northern and southern limits of the Sahara, respectively. wet habitats The histories of the Jefara and Gobero areas, as revealed by the archaeological and palaeoenvironmen- archaeology tal reconstructions, suggest that these areas were likely to have been visited and exploited for a long climate change time, acting as anthropic refugia, and therefore they have been profoundly transformed.
