Traditional ecological knowledge

Traditional ecological knowledge (TEK) describes indigenous and other traditional knowledge of local resources. As a field of study in Northern American anthropology, TEK refers to "a cumulative body of knowledge, belief, and practice, evolving by accumulation of TEK and handed down through generations through traditional songs, stories and beliefs. It is concerned with the relationship of living beings (including human) with their traditional groups and with their environment." Indigenous knowledge is not a universal concept among various societies, but is referred to a system of knowledge traditions or practices that are heavily dependent on "place". Such knowledge is used in natural resource management as a substitute for baseline environmental data in cases where there is little recorded scientific data, or may complement Western scientific methods of ecological management. The application of TEK in the field of ecological management and science is still controversial, as methods of acquiring and collecting knowledge—although often including forms of empirical research and experimentation—differ from those used to create and validate scientific ecological knowledge from a Western perspective. Non-tribal government agencies, such as the U.S. EPA, have established integration programs with some tribal governments in order to incorporate TEK in environmental plans and climate change tracking. There is a debate whether Indigenous populations retain an intellectual property right over traditional knowledge and whether use of this knowledge requires prior permission and license. This is especially complicated because TEK is most frequently preserved as oral tradition and as such may lack objectively confirmed documentation. As such, the same methods that could resolve the issue of documentation to meet Western requirements may compromise the very nature of traditional knowledge. Traditional knowledge is used to maintain resources necessary for survival.
