Chapter 14 deals with the set of methods related to resilience assessment, which is a strategic approach grounded in theory that integrates multiple methods relevant to social-ecological systems (SES) research, in order to better understand the dynamics of complex SES and to design strategic interventions. The chapter discusses Wayfinder, RAPTA, the Resilience Assessment Workbook for Practitioners 2.0, STRESS and operationalising systemic resilience as major resilience assessment tools used in SES research. It goes on to discuss the types of SES problems and research questions commonly addressed by this set of methods, as well as their limitations, resource implications and new emerging research directions. The chapter also includes an in-depth case study showcasing the application of resilience assessment methods, and suggested further readings.
