Indigenous communities use data, information, and knowledge to support climate resilience decision-making; however, the governance of that data raises challenges that have implications for tribal sovereignty. Challenges include the limited availability of environmental data for tribal lands, and the fact that available data may not reflect community values and needs. In response to these challenges, the University of Arizona's CLIMAS (Climate Assessment for the Southwest) program and Native Nations Institute, in collaboration with the U.S. Indigenous Data Sovereignty Network formed the Southwest Indigenous Climate Summit. This event serves as a forum for regional conversations regarding how to strengthen community climate resilience by drawing on the emerging framework of Indigenous data sovereignty, the availability of Indigenous knowledge, and deep place-based knowledge.
