Through research, development, and instruction in earth architecture, Calearth, the California Institute of Earth Art and Architecture, aims to address the human need for shelter. In their ideal future, everyone has the ability to use the resources found in their immediate environment to create a house that is both secure and environmentally friendly. Twenty to forty million refugees and internally displaced people today live in inadequate or slum housing, and hundreds of millions more do as well. This deficit will further worsen over the next few decades as a result of growing environmental problems and an increase in natural and man-made calamities. Calearth creates and informs the public about self-help, environmentally friendly building designs in order to satisfy this urgent need. Houses that anyone can construct with their own two hands, utilizing locally available materials like sandbags and barbed wire, and that adhere to contemporary safety, aesthetic, and comfort requirements.
