Question

What is the role of oasis in deserts?

Answer 1

An oasis is a local area in a desert where underground water reaches the surface (springs, wells or shallow water tables), and its primary role is to provide a reliable water source that permits irrigation and the growth of vegetation, especially date palms and crops like wheat, barley and vegetables, making permanent or seasonal human settlement and farming possible in an otherwise water‑scarce landscape. It also supports local wildlife and livestock by supplying drinking water and forage, so oases act as vital biological and economic hubs within deserts where people, plants, and animals can survive.
