It also discusses the process of data analysis and documentation. Chapter 2 explains the definition and key principles of the PLA methodology and a brief history of its evolution. Chapter 3 details the preparation required before carrying out fieldwork. Chapter 4 describes a number of PLA methods that can be used for participatory appraisals. Each method is accompanied by examples of applications in the field. Chapter 5 discusses documentation in the field, analysis of information generated, and preparation of synthesis reports.
