Disaster and emergency management research

In Chapter 4, Russo (2021) argues that disaster and emergency management research mostly reflects a pragmatic worldview, meaning that “the most important determinant of research philosophy [or more specifically, research design and approach] stems from the research problem itself, not the methods used” (p. 68). What exactly is Russo talking about here, and how does it relate to the use of mixed-methods in the context of disaster and emergency management research? What are the primary strengths of mixed-methods research when compared against single-method approaches? What are the primary challenges of mix-methods research, and do these challenges outweigh the primary strengths and benefits of the mixed-methods approach?
