Other than agriculture and tourism, the primary economic activity in the vast and sparsely settled desert is mining. Owing to the almost complete absence of mountain building and glaciation since the Permian (in many areas since the Cambrian ) ages, the outback is extremely rich in iron, aluminum, manganese and uranium ores, and also contains ...
Inca agriculture was the culmination of thousands of years of farming and herding in the high-elevation Andes mountains of South America, the coastal deserts, and the rainforests of the Amazon basin.

Agriculture in Israel is a highly developed industry. Israel is an exporter of fresh produce and a leader in agricultural technologies. The southern one-half of Israel is desert and irrigation is required for growing crops. The northern one-half is more conducive to rain-fed agriculture.
A desert especially rich in mineral salts is the Atacama Desert, Chile, where sodium nitrate has been mined for explosives and fertilizer since around 1850. [105] Other desert minerals are copper from Chile, Peru, and Iran, and iron and uranium in Australia.
