Botswana

Botswana is largely occupied by the Kalahari Basin, contrasted by the Okavango Delta and seasonal wetlands in the north and harder rocky landscapes in the east. The climate is semi-arid with high temperatures and variable rainfall. Earth and adobe, timber, reeds and thatch underpin many vernacular traditions, often organised in circular or courtyard compounds whose thick walls, shaded thresholds and roof forms respond to heat and scarce water.
