Turning Desert into a Garden/Food Forest

Written by Zachary Shahan

About two kilometers from the Dead Sea and two from where Jesus was christened, in the country of Jordan, Geoff Lawton of the Permaculture Research Institute and his crew created a near miracle turning desert into a lush permaculture garden.

In August in this location, Lawton says that temperatures could rise above 50 degrees Celsius (122 degrees Fahrenheit). People farming there were farming under plastic strips and using tons of synthetic chemicals and fertilizers. The idea to grow a lush forest or garden of edible plants would probably make people laugh or roll their eyes. Nonetheless, the permaculture crew had exactly this vision in mind and a little funding to help them to do it.

Lawton and his group were given about 10 acres of extremely salty and flat soil 400 meters below sea level. They designed a system to collect as much of the rainwater as possible into swales (”water-harvesting ditches on contour”), bordered the swales with mulch and, on the uphill side, nitrogen-fixing trees that helped to shade the water and prevent evaporation. Underneath the mulch, they put mini-irrigation systems. On the downhill side, they planted fruit trees — date palms, fig trees, pomegranate trees, guava trees, mulberry trees, and some citrus — mixed in with non-fruit trees and more mulch (very non-traditional agriculture).

Within four months, they had figs growing. Local agriculture experts had told them that figs could not grow there, so when the figs started growing they invited these local experts to come determine if they had de-salted the soil or if they were growing things in salty soil which “could not” grow in salty soil. They found the salt levels were dropping, but could not determine why, initially (watch the video to see why, exactly, the soil was “de-salted” — at about minute 6:00).

In December, the locals were shocked to find mushrooms growing underneath the mulch, something they had never seen due to the extreme dryness in the area. The ecosystem itself had created deep, extremely fertile soil, an amazing feat there!
