Cabeceras Aid Project was founded with a dual purpose: (1) to provide humanitarian aid to groups of indigenous people living in the Amazon Basin of South America. This aid is in the form of materials, such as tools, medical supplies, and teaching/learning materials; and human assistance, such as health education and heritage language support, that will promote the continued health and self-sufficiency of these groups; and (2) to conduct anthropological and linguistic research in collaboration with members of these groups to document their cultures and languages. The purpose of this research is to create written records of history, culture, and language for the future benefit of these groups, and for the education of people outside these groups.
