An oasis is very important in the desert?? because it is only the water ?? resource in a desert ?? so it is very important in a desert.. And the people live near an oasis for the water ?? resource.. ????

Yogita Ingle 5 years ago

The location of oases has been of critical importance for trade and transportation routes in desert areas; caravans must travel via oases so that supplies of water and food can be replenished. Thus, political or military control of an oasis has in many cases meant control of trade on a particular route.
