In traditional African societies: 1. The main crops grown were grains like millet, sorghum and maize in the savannah grasslands, and cotton and watermelon in the Sahel region between the Sahara desert and savannah. 2. Livestock like sheep, goats and cattle were raised but seldom killed since killing an animal represented a loss of wealth. 3. Large families with many children through polygamy were valued as they provided security, skills and increased wealth and honor for the family and clan.
