• Urban integration with nature

Regardless of the environmental, economic, social, health, and political crises of African countries, the traditional built environment of the African continent delivers unique lessons of sustainability. In countries such as Mali and Ethiopia, this sustainability is exhibited in two physical scales: architectural and urban. It varies from utilization of natural materials, indoor spaces of mixed use, and spatial elements such as courtyards, to compact urban form that feature narrow streets, mixed land uses and integration with surrounding natural environment.
