Hunters-Gatherers Africa’s earliest peoples were nomadic hunter-gatherers. Today, some of the San of the Kalahari Desert are still hunter-gatherers. They travel in small bands of a few related families. The men hunt with spears and bows and arrows, and the women and children gather roots and berries.
Pastoralism - Herding
Pastoralism - Herding Other early Africans eventually learned to domesticate and raise a variety of animals for food. Called herders, or pastoralists, these people kept cattle, goats, or sheep. They were nomads who drove their animals to find water and good pastures for grazing during the dry season. Millions of modern Africans are pastoral herders as well.
Rise of Agriculture
Slash and Burn Agriculture Agriculture drastically changed the way Africans lived. Growing their own food enabled them to build permanent shelters in one location. Settlements expanded because reliable food supplies led to longer, healthier lives and an increased birthrate. The increased food supply also freed some members of the community to practice activities such as working metal, making pottery, and crafting jewelry. Slash and Burn agriculture drastically altered the landscape by cutting vegetation and destroying the soil. This has contributed to desertification in some areas.
