Owe Aku (Norman grantee 2013–2023) was founded in 2012 to engage Native American tribes, Canadian First Nations, and non-Native allies in intergenerational organizing campaigns to preserve Native culture and protect sacred water and land. Through their Moccasins on the Ground program, Owe Aku provided training in non-violent direct action to activists protesting uranium mines and the Dakota Access and Keystone XL pipelines. They achieved a historic victory in 2018 when Cameco, one of the world’s largest uranium providers, closed its mining operations near the Pine Ridge Reservation and withdrew their requests for additional mines; this victory came after a decade of Owe Aku leading direct actions and mobilizing members of the Oglala Lakota tribe to contest mining permits. Owe Aku also built a legal case, providing evidence that Cameco violated waste handling requirements and that regulatory agencies had failed to consult tribal representatives on the environmental and cultural impacts of mining.
