Grasslands and water in a wetter period
During the fifth to third millennia BCE, many Saharan regions still contained usable grasslands, lakes and seasonal water. People herded animals alongside gathering, fishing and hunting. Camps, tools and animal remains preserve varied livelihoods. Rainfall, pasture and herd condition shaped movement, organized by families and communities across seasonal locations. Knowledge of routes passed through experience and continuing relationships among travelers.
Animals and everyday worlds in rock art
Painted and engraved images depict cattle, wild animals and human activities. Livestock supplied food and other resources and entered rituals, wealth and group relationships. Care and the search for pasture required work; illness or inadequate water affected households. Styles and subjects varied across regions. Makers selected poses, scenes and locations, turning rock surfaces into places used repeatedly for representation and activity.
Adapting to diminishing water
As conditions became drier, some lakes and pastures contracted. Communities changed routes, residence patterns and food strategies. Some relied more on valleys or stable water, while others maintained seasonal herding. Movement carried animals, skills and relationships into new environments, with exchanges linking villages and pastoralists. Later desert livelihoods drew on knowledge of water and mobility accumulated during these long environmental adjustments.
