At each level of decision-making for water use, a number of factors influence individual and collective decisions to adapt to changing water supplies. Understanding how and why stakeholders make such decisions, including what information they use and what tradeoffs they consider, is crucial for informing future water management interventions. As part of the Collaborative Research Framework (CRF), a stakeholder analysis will be conducted in two case study basins in order to identify key individuals and organizations that represent major stakeholder groups, such as agricultural, tribal, environmental, and municipal and industrial water users. We will analyze the values, needs, and relationships among these stakeholder groups. In addition to soliciting expertise from stakeholders, we will also develop Technical Advisory Groups (TAGs), who will iterate with the project team to co-produce knowledge and understand the applications of research findings in context.
