The Earthen Architecture Initiative (EAI) seeks to further the conservation of earthen architecture through international activities and institutional partnerships. Advancing the discipline of earthen conservation is the organizing principle for all of the EAI’s activities—which include model projects that improve the way conservation interventions are carried out in different parts of the world, pursuing research that addresses unanswered questions in the field of earthen conservation, and disseminating information regarding appropriate conservation interventions on historic buildings, settlements, and archaeological sites composed of earthen materials.
