landscape in current new developments.
        
        
          All theseaspects of past andmodern life can
        
        
          be related to food and settlement patterns
        
        
          as well as technological changes which are
        
        
          evidently affected by the environment and
        
        
          climatic conditions through time. Favorable
        
        
          climaticconditionsandincreasedinteraction
        
        
          amongst communities pursuing different
        
        
          but complementary subsistence strategies
        
        
          made possible the sharing and exchange
        
        
          of ideas and systems of knowledge that
        
        
          once held sway within specific ethnic and
        
        
          subsistence groups.

          Forexample, thehunter-gathererwayof life
        
        
          changed due to migration and settlement
        
        
          in their domain of pastoralists and later
        
        
          of agrarian communities, along with the
        
        
          incorporation of knowledge from all the
        
        
          groups. This created a vibrant community
        
        
          that would elevate individuals and
        
        
          personalities from the groups to leadership
        
        
          positions.Certain
        
        
          material
        
        
          indicators
        
        
          combine to support this proposition:
        
        
          material signatures that relate to shifting
        
        
          settlement patterns, fortification, mortuary
        
        
          practices, territoriality, and migration,
        
        
          all of which combine to support warfare
        
        
          and violence hypotheses. The ability to
        
        
          control access to resources or trade routes
        
        
          is an important element of emergent
        
        
          complexity and political centralization.
        
        
          Physical and military power, embedded
        
        
          in this proposition, can restrict access to
        
        
          wealth creating resources and production.
        
        
          For instance, control over iron production
        
        
          was quite important for rulers, and the
        
        
          physical force needed to monopolize
        
        
          access to iron resources that were beyond
        
        
          the political control of the state capital was
        
        
          probably a necessity. Once asymmetries
        
        
          in power had been established, what
        
        
          strategies do leaders use to stay in power
        
        
          and accumulate more wealth, status, and
        
        
          power? The pathways and mechanisms
        
        
          through which power is centralized will
        
        
          differ from case to case. In this case, elites
        
        
          initially accumulated wealth in cattle and
        
        
          later invested in gold and ivory trade with
        
        
          the coast. To do so, they also invested
        
        
          in local and regional infrastructures
        
        
          considered as viable for communities living
        
        
          and exploiting different but complementary
        
        
          resources. Therefore, these communities
        
        
          were willing to comply and be incorporated
        
        
          into the regional political economy.
        
        
          There are lessons to be learnt from these
        
        
          past commitments andwhichcanbeutilized
        
        
          in enhancing Africa’s economy today. For
        
        
          example, systems which allow for sharing
        
        
          and facilitating the movement of goods and
        
        
          knowledge across borders are important in
        
        
          realizing Africa’s economic growth.
