Humans Have the Potential to Turn Deserts into a Green Oasis

I hope you find this video a source of hope and that it empowers you to be part of the solution. If you'd like to follow my work and keep up-to-date with our current projects, courses, and videos, please join me at the Permaculture Circle (TPC) where members enjoy free access to my curated collection of 100+ videos and animations: https://start.geofflawtononline.com/p.... Today, I'm starting on the Greening the Desert project's rooftop terrace, in the Jordan valley, overlooking Palestine and the city of Jericho—one of the oldest inhabited cities in the world and a region that was once considered part of the 'fertile crescent'. These are some of the most severely damaged regions on earth and I'm going to show you a perennialized Brazilian Spinach, also known as the Alternanthera sissoo. It's an edible green classified as a tropical vegetable from the Amazon, growing here in the desert just because we're using wicking beds, the most efficient watering system in the world. One of the cheapest ways to make a wicking bed is with a bulk liquid container (BLC), cut in half. For those that want to get growing, I've included simple step-by-step instructions within the video. Due to their minimum use of water, and minimal loss of water through evaporation, they’ve proven very successful and are a large part of our project both on the site and as an outreach demonstration in schools, urban backyards, and refugee camps. They're just so straightforward to construct, and within no time anyone can create a garden that soaks up water with capillary action. There are other efficient methods for irrigating in drylands. Greywater from sinks and showers can be cleaned by moving it through a reed bed. Reed beds can be set up to collect domestic water, clean the suspended nutrients from it, and distribute it through a movable output, such as a hose. Here, we see Haadeeyah, one of our wonderful interns, maintaining our kitchen reed bed. It services two of our kitchens and we are re-using the water for fruit trees around the system. Subsurface irrigation is best in drylands and you can use sunken pipes and drip-lines to deliver water to trees at the root level, which we are doing at the project, but I don't cover it here. Swales are the best example of subsurface seepage, as they put hundreds of liters of water beneath the soil, but again that's for another time. If we can do this here, imagine what’s possible in your climate. Desertification is increasing worldwide, but with careful design, we can demonstrate permanent productivity and landscape rehabilitation. #wickingbeds #greeningthedesert #permaculture
