Lead CCASS Contact: 

Tribal nations within the United States are some of the communities most vulnerable to climate change impacts.  The Tohono O’odham Nation, encompassing almost 4,500 square miles in the southwestern portion of Arizona, is taking the pro-active step of developing a climate change adaptation plan in order to help it respond to impacts such as higher and prolonged heat events, the potential for larger flood events, higher wildfire risk, and potential stress on its water resources.  CCASS is coordinating the development of the plan in collaboration with the Tohono O’odham Water Resources Department.
