Growing political action by indigenous peoples has led to increased recognition of the importance of their knowledge, and scientists are coming to recognise its value. In the Arctic, where efforts to understand the effects of climate are urgent, traditional knowledge has received increased attention over the past few decades. Sami reindeer herders work with scientists to document snow conditions and study what they suggest about herding practices under future climate conditions. And in 2007, the North Pacific Research Board allocated US$1 million to traditional-knowledge research. Scientists must also work together with indigenous peoples to find new ways of gathering traditional knowledge. A successful example is the use of Global Positioning System units by hunters in Nunavut, Canada, to record their experiences as they travel.
