Rangelands are types of land within Arid and Semi-Arid Lands (ASALs) dominated by natural or semi-natural vegetation suitable for extensive livestock production and wildlife conservation, but are less appropriate for arable farming due to limitations such as scarce and unreliable rainfall, high evapo-transpiration, and low soil fertility, and very short growing season that hardly reaches 200 growing days. The main economic activity in the rangelands is pastoralism that is characterized by low external input livestock production, which relies mainly on natural vegetation.
