Desertification is the process in which fertile land slowly turns into sand-filled deserts. It’s happening all around the world, and increasingly so in the United States. It’s a direct result of poor environmental decisions, livestock grazing, and landowner neglect. The good news is that it’s also reversible and preventable. Allan Savory, a research biologist and President/Co-Founder of the Savory Institute, recently gave an inspirational TED talk about healing our land. His background on the subject is impressive, and should give us pause to heed his words. In the 1960’s while working in Southern Rhodesia (Zimbabwe), he came to understand what… read more

In the desert these challenges are only multiplied by extreme heat and aridity. Furthermore, land that is currently identified as dry land or plains will soon, due to climate change and soil degradation, be… read more
