A Surprising New Way of Gardening in the Desert
Have you ever heard of a swale? Most people haven’t unless they have been practicing a whole new way of gardening in the desert like they are in the country of Jordan right now. A swale is a long, narrow trench which collects rainwater for irrigation.
On a 10 acre piece of land you could have 1 ½ kilometers of swale to maximize the collection of the scant rainfall. When full, the swale can provide as much as a million liters of water to soak into the landscape. They are about 2 meters wide and ½ a meter deep. When gardening in the desert, you need to get the most out of the little rain as you can.
Then organic mulch is placed on the ridges above the swale to a depth of about ½ meter deep. Micro-irrigation systems are then put under the mulch.
