Rolnicze wykorzystanie wód na Saharze

The Sahara has exceptionally unfavourable natural conditions for farming. The extremely low precipitation and the high prevailing temperature allow for plant cultivation only in artificial irrigation conditions. The author discusses the regions' water resources (precipitation, surface and underground waters) and describes various ways of their use for agriculture. He also enumerates the main advantages and limitations of the technologies used, both traditional and modern, while placing special emphasis on the natural conditions of irrigated agriculture.
