Mali

Mali stretches from the Sahara through the Sahel to wetter southern savannas, with the Niger River and its inland delta forming the country’s principal geographic corridor. Climate ranges from hyper-arid in the north to strongly seasonal in the south. Earth and banco architecture is especially important, often reinforced with timber and renewed after seasonal rains; thick walls, shaded courtyards and monumental Sudano-Sahelian forms make climate and maintenance visible in the architecture.
