East Africa

East Africa contains some of the continent’s most varied terrain: the Great Rift Valley, the Ethiopian Highlands, the Great Lakes, the Horn of Africa and the Indian Ocean coast and islands. High plateaus, volcanic landscapes and major peaks contrast with arid lowlands and tropical coastal zones. Climate ranges from equatorial and highland conditions to severe aridity in the Horn, with monsoon-influenced coasts and island environments adding further diversity. This geography produces exceptionally varied settlement patterns and ecological zones. Its building traditions are equally diverse: highland and interior regions make extensive use of stone, earth, timber and thatch, while the Swahili coast developed coral-rag and lime construction with mangrove timber, shaded courtyards and verandas shaped by the humid maritime climate and Indian Ocean exchange. In drier areas of the Horn, stone and earth traditions respond to limited timber and strong thermal variation. Across the Great Lakes and other wetter zones, earth, timber and plant-based roofing remain important vernacular materials.
