Hello,
I don’t know which region are you talking about but I have this :
In the middle of immense desert expanses, the oases appear like islands of greenery. To irrigate crops, sedentary peasants use wells or underground galleries called foggaras. They bring the water to the foot of the plants through a network of small earthen channels
Hope it helps a bit!
Byye and don’t forget I’m proud of you!!<333
