Could a simple circular garden help solve food insecurity in some of the world's harshest climates? In this episode of Roots and All, I'm joined by Sam Evans, whose dissertation took him to Lesotho to explore keyhole gardens — ingenious compost-fed growing systems that help communities grow food sustainably in extreme conditions. We discuss how they work, the wider benefits they bring, and what they could teach us about growing food in a changing climate.
