useful trees & shrubs in dryland permaculture

Doctor Keller Horton is not a medical doctor. He comes from a background of thirty five years in education and curriculum design. During that time he also completed his Master’s Degree specializing in Environmental Law and Regional Design Methodologies for Development in Lower Income Countries. Dr. Horton has over 50 years of gardening experience. His lessons began early in life with his parents and both sets of grandparents on farms in West Texas. He caught the Permaculture, ＂bug＂ while doing You Tube research on aquaculture greenhouses. While watching a video on aquaculture, a mysterious thumbnail video title appeared on the right side of the screen. The title simply read, ＂Greening the Desert＂. The temptation to click on that video was unbearable. When he watched the video, an entire new world of creating self-sustaining food forests was revealed. Twenty-seven books and 100 videos later he decided to enroll in the fantastic permaculture course offered by the Permaculture Research Institute in Jordan. Yes, Jordan, in the Middle East where the Jordan river separates the nation of Israel from the Hashemite Kingdom of Jordan. The course site was located right within one of the hottest, driest, most rocky, and inhospitable spots you could ever imagine on Planet Earth.
