A new website focused on Scenario Planning for Climate Adaptation,, has been developed by CCASS and the DOI Southwest Climate Science Center. 

About Us

CCASS/NNCAP welcomes Valerie Small!

Dr. Valerie Small (Apsaalooke'-Crow) has joined the Native Nations Climate Adaptation Program as an Assistant Research Scientist. Dr. Small will be working with Tribes in the Southwest Region in collaboration with CCASS and NNCAP within the Institute of the Environment as well as the Southwest Climate Science Center (SW CSC). She will develop and deliver educational training modules to increase their environmental technical capacity in preparing for, as well as predicting near-term/future effects of climate change.

Prior to joining the UA, Valerie was a training consultant with Colorado State University, Natural Resource Ecology Lab (NREL), working with the North Central Climate Science Center. Her experience includes developing and conducting training and research to support North American Indigenous Tribes adaptation planning efforts to prepare for the effects of a warming climate.

The US Department of Defense has made a highly visible push to incorporate climate change adaptation into all aspects of their mission, from training and housing soldiers and their families, to protecting natural resources on their facilities, to geopolitical strategic planning.  The DoD was recently the first US agency to release a “Climate Change Road Map” outlining the Department’s concerns and plans for climate change adaptation.  Secretary of Defense Chuck Hagel refers to climate change as a “threat multiplier,” echoing the consensus in the climate adaptation community that climate change is not so much of a new risk, but an enhancement and modification of existing risks faced by people and organizations.  We are excited to be part of DoD’s early efforts and climate adaptation planning with our Climate Change on Southwestern DoD Facilities project.

The U.S. Southwest presents an intensified suite of climate change impacts likely to be experienced by many DoD facilities.  In a project funded by the Strategic Environmental Research and Development Program (SERDP), UA researcher Rafe Sagarin is engaging with DoD managers through interviews, workshops and case-study pilots across a range of DoD operations in the Southwest to develop robust approaches to climate change risk assessment, mitigation and adaptation, supported by a set of climate adaptation tools that can be used across DoD operations. The approach combines social and biophysical sciences to determine management needs and then develop tools to help DoD access the most relevant and current climate data available. The process also emphasizes capacity building and network building so DoD personnel can assess new climate threats and make adaptive decisions.
