The document discusses and compares two East African pastoralist groups, the Turkana and Masai. The Turkana are semi-nomadic herders who move their livestock in response to changing environmental conditions and divide their herds based on water availability, relying on social networks for flexibility. The Masai are mainly cattle herders in a more moist environment and practice transhumance rather than opportunistic movement; their social organization involves patriarchal households and age sets that determine status. Both groups rely on livestock, especially cattle, for their livelihoods and place high cultural importance on warriorhood, but treat women as marginalized and their status depends on bearing sons.
