  abstract = {{A} volcanic tuff rock known as cangahua ({E}cuador) or tepetate ({M}exico) is found throughout the {A}ndes. {P}roblems have arisen as the layers of light but fragile soil that once covered the tuff have been lost for both natural (environmental) reasons and because of over-cultivation. {W}hen the soil is gone, the tuff is impermeable and sterile. {N}ow, a project in {E}cuador has determined that the tuff itself can be reclaimed and is supporting a programme that sends bulldozers to the tuff regions to break up the rock and create a new fertile soil.},
