Explore the use of Traditional Knowledge (TK) in the context of climate change. One definition of Traditional Knowledge (TK) is that TK is “a cumulative body of knowledge, practice, and belief, evolving by adaptive processes and handed down through generations by cultural transmission, about the relationship of living beings (including humans) with one another and with their environment (NCA 2014).” The potential use of TK to inform climate change assessments and adaptation planning has recently received significant attention nationally and internationally. Although the potential benefits of applied TK are widely recognized, it is important that any use of TK be managed to ensure proper protection of tribal cultural resources. As summarized by Dalton et al. (2013), “traditional knowledge can inform tribal and non-tribal understanding of how climate change may impact tribal resources and traditional ways of life. However, its use in climate change initiatives should ensure respect for the values associated with these knowledge systems and protection of sacred knowledge and wisdom, and give tribes decision-making authority over how traditional knowledge is used.” A recent publication, Guidelines for Considering Traditional Knowledges in Climate Change Initiatives (2014), was developed by tribal and non-tribal participants in the Climate and Traditional Knowledges Workgroup (CTKW) as a framework to guide appropriate use of TK in the context of climate change.
