The UNESCO (United Nations Educational, Scientific, and Cultural Organization) World Conference on Science for the Twenty First Century concluded that “Traditional and local knowledge systems, as dynamic expressions of perceiving and understanding the world, can make, and historically have made, a valuable contribution to science and technology.” Productive collaborations exist between Western and native scientists in environmental research, land use, geographic information science, and hydrology, yet too often, research has been done on indigenous communities not with them. Traditional knowledge has not been valued, and science education for indigenous youth has not included the methods and traditions of native sciences. In this symposium, faculty from three tribal colleges will describe how, in their institutions, Western and native sciences are woven together in research and in teaching.
