This document provides an overview of participatory rural appraisal (PRA). PRA is a bottom-up approach that involves local communities in the analysis of their situation. It uses flexible and visual tools like mapping, modeling, diagrams and rankings to facilitate discussion. The key principles of PRA are participation, flexibility, optimal ignorance and triangulation of data. Some techniques include semi-structured interviews, participatory mapping, seasonal calendars and wealth rankings. PRA aims to ensure projects address local priorities by learning from rural people's own analysis of problems and solutions.
