Indigenous environmental movements have been important actors in twentieth- and twenty-first-century global environmental politics and environmental justice. Their explicit foci range from the protection of indigenous environmental stewardship systems to upholding and expanding treaty responsibilities to securing indigenous rights in law and policy. This chapter suggests that these movements open important intellectual spaces for thinking about the function of environmental governance institutions in addressing complex environmental issues such as clean water and forest conservation.
