A typology is a tool of categorization and classification, one that makes complex parts of a process or knowledge base clearer. This session will highlight a new endeavor to create a typology for drought decisions that emphasizes the human and social dimensions of drought preparation, response, and adaptation. The goal is to develop and refine key conceptual categories that influence nonmeteorological factors affecting drought decision-making. Questions to address include the following: What are the types of drought decisions and who makes these decisions? Under which legal and regulatory mechanisms and constraints are they made? What factors determine the decision space in which an individual operates? What is the interaction among drought decisions in a given region or watershed? To what extent do decision-makers enable or constrain one another’s decisions? Are there common explanatory factors that explain these interactions?
