Book excerpt: Earth building is not only one of the oldest, but also one of the most modern construction methods of our time. What economic, environmental, and social conditions are necessary for an upscaling of earth to occur? The authors present a wide scope of built und unbuilt projects as well as strategies that can be implemented to edify processes of building, adapting the use of earth to each unique culture and context. The advantages of this material become manifest: from its worldwide availability to the possibility of comprehensive recycling, from climate-neutral production to socially just implementation, including a focus on emerging economies. This book reveals the incredible potentials of earthen architecture - for people and for the entire planet.
