9.1 Africa’s Geography and Climate

Africa's diverse landscapes shaped early human societies. From the vast Sahara Desert to lush rainforests and fertile river valleys, each region fostered unique ways of life. These geographical features influenced population movements, trade routes, and cultural exchanges across the continent.

Hunter-gatherer societies like the Baka and San adapted to their environments with deep knowledge and skills. As agriculture emerged, communities in savannas, river valleys, and rainforests developed new techniques and social structures. This shift led to permanent settlements, specialized labor, and complex societies.

1 of 3

• Africa's varied landscapes and climates shaped early human societies
  • Sahara Desert in the north largest hot desert in the world, nomadic lifestyles adapted to arid conditions, oases provided water and supported trade routes (caravans)
  • Savannas and grasslands in central regions covered vast areas, abundant wildlife for hunting and gathering, eventual development of pastoralism (herding) and agriculture
  • Rainforests in central and western regions (Congo Basin), rich biodiversity and resources, hunter-gatherer societies thrived, provided wood, medicinal plants, and game
  • Nile River Valley and East African Rift Valley fertile soils and reliable water sources, supported early agricultural settlements (Egypt) and civilizations, served as migration corridors
• Geographical barriers and features influenced population movements and interactions
  • Sahara Desert acted as a barrier between North and Sub-Saharan Africa, limited cultural exchange and trade
  • Nile River facilitated trade and cultural exchange connected Egypt to Nubia and interior of Africa
  • East African Rift Valley served as a corridor for human migration earliest evidence of human ancestors found here (Lucy)

Hunter-gatherer societies

• Baka people of the Congo Basin rainforests
  • Semi-nomadic lifestyle based on hunting, gathering, and fishing moved seasonally to access resources
  • Deep knowledge of forest resources and medicinal plants used for food, shelter, and health
  • Egalitarian social structure with shared decision-making no formal hierarchy or leaders
  • Animistic beliefs and reverence for the forest spirits believed in spirits inhabiting natural world
• San people of the Kalahari Desert and surrounding areas
  • Nomadic lifestyle adapted to arid conditions moved frequently to find water and game
  • Expert tracking and hunting skills using bows and poisoned arrows able to hunt large game (antelope)
  • Gathering of wild plants, roots, and nuts (mongongo nuts) provided essential nutrients
  • Egalitarian society with fluid leadership based on consensus decisions made through discussion
  • Belief in a supreme being and the importance of ancestor spirits conducted rituals to honor ancestors
• Shared characteristics of hunter-gatherer societies
  • Small, mobile bands with strong social cohesion typically 20-50 individuals, close-knit
  • Intimate knowledge of the environment and its resources knew where to find food, water, shelter
  • Oral traditions and storytelling to pass on knowledge and values no written language, relied on memory
  • Minimal material possessions and emphasis on sharing few personal belongings, shared resources

Agricultural communities

• Savannas and grasslands of the Sahel and East Africa
  • Domestication of crops like sorghum, millet, and cowpeas staple grains and legumes, well-suited to climate
  • Herding of cattle, sheep, and goats provided meat, milk, and hides, mobile lifestyle
  • Gradual transition from nomadic pastoralism to settled agropastoral communities combined farming and herding
• Nile River Valley and Nile Delta
  • Annual flooding deposited fertile silt for agriculture allowed for predictable farming season
  • Irrigation systems developed to control water distribution canals and levees to manage flooding
  • Surplus agricultural production supported population growth and urbanization allowed for specialization and cities
• West African rainforests and coastal regions
  • Cultivation of yams, oil palms, and kola nuts staple crops adapted to humid climate
  • Slash-and-burn agriculture to clear forest patches temporary fields, allowed soil to regenerate
  • Development of iron tools for farming and forest clearing made clearing land and farming easier
• Environmental factors influencing agricultural development
  • Reliable water sources (rivers, lakes) and fertile soils essential for crop growth
  • Suitable climates for crop cultivation adequate rainfall and temperature
  • Presence of indigenous plant and animal species for domestication wild ancestors of crops and livestock
• Social and technological innovations accompanying agriculture
  1. Development of sedentary villages and towns permanent settlements, mud-brick architecture
  2. Specialization of labor and rise of crafts and trade potters, weavers, metalworkers, merchants
  3. Emergence of social hierarchies and centralized leadership chiefdoms, kingdoms, pharaohs (Egypt)
