South Sudan

South Sudan is structured by the White Nile and the vast Sudd wetlands, surrounded by savannas, floodplains and higher ground toward its borders. The tropical climate alternates strongly between wet and dry seasons, and flooding is a major local condition. Traditional construction uses earth, timber, reeds, grasses and thatch, with lightweight or repairable forms, raised thresholds and steep roofs responding to rainfall, heat and seasonal water.
