Шаблон:Infobox landform The Ironstone Plateau (jabal hadid) is a region in the south and west of South Sudan.
Topology and rainfall
The land in the south and west of South Sudan slopes down to the northeast from the Nile-Congo Divide towards the Bahr el Ghazal swamps. The divide is formed by a plateau rising Шаблон:Convert above sea level, with some peaks that rise to Шаблон:Convert. Rainfall is higher on the plateau than in the lower clay floodplains.Шаблон:Sfn The rainy season lasts from May until November. Annual rainfall is Шаблон:Convert.Шаблон:Sfn The plateau drains into the floodplain through rivers that cross an ironstone peneplain and then spread out into deltas and swamps.Шаблон:Sfn The soils of the plateau have little capacity to hold water, so most of the run-off drains into the floodlands.Шаблон:Sfn The many streams draining the plateau have formed steep and narrow valleys.Шаблон:Sfn
Soil and vegetation
The Ironstone Plateau takes its name from the hard red lateritic soil called ironstone that covers almost the entire area. These soils are often thin and may be unsuitable for agriculture, except in the Green Belt in the extreme southwest of Western Equatoria and in a region around the Acholi Mountains in the Torit County of Eastern Equatoria.Шаблон:Sfn The country north and east of the ironstone plateau is covered in clayish black cotton soil, mostly grasslands that are prone to flooding. The black cotton soil cracks when it is dry, but expands and becomes sticky in the rain, making travel difficult. The ironstone plateau has more trees and travel is easier.Шаблон:Sfn The plateau and peneplain are mostly wooded.Шаблон:Sfn
People and economy
The people of the plateau generally speak Ubangian languages while the people of the floodplains are Nilotic.Шаблон:Sfn The plateau population includes Zande in Western Equatoria and Bari speakers in Central Equatoria on either side of the Nile.Шаблон:Sfn They raise some livestock and engage in rain-fed agriculture, growing cereals such as Sorghum and pearl millet, vegetables and cassava in mixed croppings.Шаблон:Sfn Other crops are oil seeds, groundnuts, sesame, cowpeas and okra, and mangoes, citrus and melons.Шаблон:Sfn The best soil for agriculture is beside the streams that drain the plateau.Шаблон:Sfn The forests yield mahogany from the Raga region and plantation teak.Шаблон:Sfn
