How did Africa's climate zones affect people ability to raise crops?

Africa's diverse climate zones significantly influenced agricultural practices across the continent. In regions with arid climates, such as the Sahara, limited water availability restricted crop cultivation, leading to pastoralism instead. Conversely, areas with more favorable conditions, like the Nile Valley and the West African savannas, supported the growth of staple crops such as millet, sorghum, and rice, enabling settled agriculture. This variability shaped the diets, economies, and lifestyles of different African communities.
