However, desert farming has been practiced by humans for thousands of years. In the Negev, there is evidence to suggest agriculture as far back as 5000 BC. [1]

Extensive farming most commonly means raising sheep and cattle in areas with low agricultural productivity, but includes large-scale growing of wheat, barley, cooking oils and other grain crops in areas like the Murray-Darling Basin in Australia.
For instance, it might be difficult to tell if desertification or desert expansion is the result of climate change or human activity. [19] Desertification in Africa is exacerbated by human factors such as deforestation, overgrazing, and unsustainable farming methods such as monoculture and excessive use of chemical fertilizers.
