The Karoo is a semi-desert natural region of South Africa. There is no exact definition of what constitutes the Karoo and therefore its extent is also not precisely defined.
The Karoo is partly defined by its topography, geology and climate, above all
its low rainfall, arid air and extremes of heat and cold.
It also hosted a
well preserved ecosystem hundreds of millions years ago, which is now represented by many fossils.
The region's name derives from a Khoi word meaning dry.
Human footprint includes roads and dams.
